New F3 based integrated flight controller frame coming soon!

F3FC-Tricopter

This is our new RCExplorer F3FC Tricopter flight controller/PDB frame. Designed based on all the feedback we’ve received since the release of the Naze32 frame. This frame has it all.

Equipped with a SMT32F303CC processor which runs at a higher clock speed than the previous F1 chip. It also has a dedicated float point math processor to reduce processor load, freeing up resources to run other fun stuff like GPS, RGB LED’s, compass, blackbox logging, SBUS, OSD and such. This processor also allows for 3 dedicated UART’s which vastly improves connectivity. It’s now possible to run GPS, LED’s, OSD, external compass(via I2C) and SBUS at the same time. The board also has a I2C port and CAN bus which allows for future expandability. It also has a direct connected LED pin for controlling those really cool addressable RGB LED’s.

To save weight and make the build easier and more streamlined, the F3FC tricopter frame is also a power distribution board! Instead of having 2 separate boards and wires going everywhere you now just solder everything to one board and no extra wires between the boards are required. It makes assembling the copter easier, as you don’t have to juggle both boards and arms around at the same time while trying to get everything in place.

That’s not all when it comes to power. The F3FC frame also has a built in 3A switching BEC! This BEC can easily drive the servo, flight controller, OSD, UART devices, RGB LED’s without even running warm. It’s super clean and it also has selectable output voltage of 5V, 6V and 8V, the latter mainly used to power high voltage servos. If you have the BEC set to 8V you can, by bridging two solder points power the UART ports via a built in linear 5V regulator, so that you don’t fry your sensitive 5V expecting devices. The components for the switching BEC are well protected in a crash as they are hidden within the front spacer.

Also mounted inside of the front spacer is a MS5611 high sensitivity, high quality pressure sensor. Together with an external GPS the copter can now do position hold. Mounting the sensor inside of the front spacer keeps it out of direct airflow giving much more accurate readings.

Another great feature is the built in current sensor for monitoring mAh used. To me this is huge. It allows for a much more accurate way of knowing how much juice is left in your battery. This information can easily be relaid through telemetry to your RC transmitter together with the real time current draw and battery voltage (which naturally also is built in to the board).

To give the best flight experience the MPU6000 Gyro/accelerometer chip is used. It’s the least vibration sensitive chip commonly available, which means crisper performance due to lower noise. The MPU6000 is connected through SPI instead of I2C, which allows for much higher update rates. This together with the F3 chips capability of running lower loop times also improves the flight performance greatly.

Another huge leap in flight performance is the feedback enabled BMS210 servo. The flight controller now knows where the servo is at all times, which allows it to much more accurately control the tail. The F3FC frame has a dedicated feedback pad straight on the board for very easy hook up. All ESC’s also have surface mount pads straight on the board, which makes for a very clean build and saves a ton of space on the top of the frame.

To clean up the wiring even more there is now through holes that matches the pin spacing of the beeper. You can now solder the beeper straight to the board without any cables. There is also RAW battery voltage pins to power FPV equipment and such on the top of the frame. No more having to run wires on the side of and then in-between the frames.

Lastly the frame has 2 PWM channels, one of which can be used for PPM receivers. Serial receivers can be plugged into any of the UARTs, but UART1 has a selectable 3.3V/5V selector solder bridge for powering 3.3V spectrum satellites or “normal” receivers.

The F3FC frame is a drop in replacement for the Naze32 frame. You can use it with both the Mini Tricopter and the V3.5 without any modifications.

The board should be released 2-3 weeks, so keep an eye out!

The BMS210 servo now comes with feedback wire pre-installed!

BlueBird BMS 210 Feedback

No more modifying your servo! We’ve now redesigned the original BMS 210 servo to include a feedback wire straight from the factory. This wire is used to accurately determine at which angle the servo is positioned at all times. The wire plugs in to the flightcontroller and the information is used by the latest versions of the TriFlight code to vastly improve the yaw performance of the tricopter.

The price for the new RCExplorer 210 DMH Feedback servo is the same as the previous non feedback version.

Note: You don’t have to use the servo feedback wire. The servo will work just like any normal servo if you don’t connect the wire.

All electronic kits now comes with the new feedback version of the servo.

New FPV video! – “Fire and Ice”

Lately almost all my flying has been with the Mini Tricopter. I haven’t flown the Tricopter V3.5 in FPV for quite some time. When I finally found the perfect V3.5 motor I decided to build a really nice, pimped out long range setup and get out there and do some flying, in the style I used to do.

As soon as I took off I fell in love all over again. I had forgotten how smooth and swooshy this thing is. It feels like the air is thicker, smoother and more flowing than when flying the smaller platforms. After landing it feels like you’ve had a 15 minute long hug. Man I’ve missed flying this thing.

New Mini Tricopter motor

Emax RS2205

I really like testing new electronics. Improving the performance, feel and quality is something I continuously strive for. With the new LittleBee30A ESC’s a broader range of power setups are possible and I think I found the perfect combination for the Mini Tricopter. The Emax RS2205 2300kV drew too much current for the SN20A’s that we previously used. I was also concerned that the flight times would suffer with such a tiny motor. But it turned out that hovering flight time actually is the same (~14 minutes) as with the BE2208 on a 4S1800mAh battery. It’s not quite as efficient in the hovering throttle range, but the lower weight compensates for this, and it provides more thrust.

At full throttle this little motor draws 31A, producing 1200 grams of thrust, while swinging a 6×4.5 HQ prop. You would think this would fry the poor little copper strands in the motor, but with its built in cooling system which sucks air through the motor, cooling both the motor and the powerful N52 magnets, it can do this without overheating. This is quite amazing considering that the Emax RS2205 only weighs in at 30 grams with wires! It’s also incredible smooth thanks to the Japanese NMB Bearings, really high quality stuff right there.

With the Emax RS2205 the copter does feel more perky and crisp. The breaking force of the Emax motors are amazing, which gives a very accurate feedback.

If you plan on going over to the Emax setup, I highly recommend using some good quality batteries with high C-rating to feed these power hungry little beasts.

Mini Tricopter Arms back in stock!

The Mini Tricopter arms are finally back in stock, which means that the Mini Tricopter kit is also off backorder. The Full size arms are, according to the tracking, scheduled to arrive on the 31st of March.Mini Tricopter 6x4.5x3

In the meantime I’ve done some tests with 6×4.5×3 props on the Mini Tricopter and it’s pretty awesome! The motors have so much torque that they still come down almost cold. Will do more tests to see how well the setup holds up compared to the standard 6×4.5 which have phenomenal performance. Have any of you tested out any other prop configurations?

Back to the rounded edge carbon fiber arms. Second quality arms available in the meantime.

We’ve run out of arms for both the MiniTricopter and the Tricopter V3.5. The sharp corner arms turned out to be too difficult for the manufacturer to make reliably and the yield was low. (Though they didn’t inform us of this until we put in the latest order). So now we’re going back to the rounded corner arms again. But from the new manufacturer, so the quality will be improved compared to the very first arms we sold. The new arms are being made and will ship out to us soon.

In the mean time we can offer the tricopter kits with “second quality arms” at less than manufacturing cost. A $7 discount is available for the Tricopter V3.5 kit and $5 discount for the MiniTricopter. Use the discount code uglytriarms for the Tricopter V3.5 kit and uglyminiarms for the MiniTricopter while in your cart. For spare arms (both full length and 1/2 length) that are not part of a kit you can use the coupon code uglyarm ($1 discount per arm). Make sure that the coupon code works before proceeding to the checkout page.

By “second quality” we mean that the arms have not passed our usual quality control and may be scratched, somewhat uneven on the surface, of a little bit uneven length/width, or with other minor faults. They are still straight and fully functional (maybe a bit of sanding down of a bump might be needed, but not more that that). These arms are available and in stock even if the “normal quality” arms are on backorder, which means that your tricopter would be shipped without delay. The arms may be of the rounded or sharp edge design, but they will not be mixed. You cannot choose which type you will get.

Tricopter V3.5 Electronics kit

Finally! After months and months of testing different motors, ESCs and props, I’ve finally found the optimum combination of components

V3ElectronicsKit1 copy

The kit contains the brand new, custom wound 2217 stator size, 1300KV motor. Tuned specifically to provide the best efficiency during hover yet still have tons of power for when you need it.

BE2217-1300kv-1cut

The über awesome motor uses a 4mm shaft to better handle impacts and abuse. It weighs 77g with cables, which means it has a lot of copper in the windings which provides mounds of torque to swing 8×5 propellers on 4S, or 9×5 on 3S.
LittleBee30-1crop

To turn the super awesome motors 3 LittleBee 30A ESC’s are used. These ESC’s use the Silabs C8051F390 processor with dedicated gate drivers to achieve super fast switching which increases efficiency, throttle response and thrust generated by the motor. They work on 2-6S and are flashed with BLHeli 14.3 with dampened light enabled by default. They are also Oneshot125 compatible and together with the active breaking they give a really crisp and precise control over the copter.270mmWire2crop

Also included in the kit are 3 – 432mm long 18 gauge power and servo wires, the perfect length for the Tricopter V3.5.HQ8x5CW

A power package is only as good as the propellers providing the thrust. After testing many, many props these are by far the best ones I found. The 8×5 Thin electric by HQ. They are carbon fiber reinforced to provide good stiffness, they are light weight which improves quick throttle response (which makes the copter more stable as the updates from flight controller is executed quicker), They also have the best “out of the package” balance out of the bunch (you should still always balance your props!). They are also very efficient on this setup and they cut the air better than other multirotor specific props.
210DMHRCEx

Lastly, the kit also includes the raining champion of tricopter tail servos, the Blue Bird 210 DMH. Tough, powerful, precise and reliable, this servo performs again and again.

The price tag for the Tricopter V3.5 power package is $150. Get them while they’re hot!

New video! – Remove your props!

Remember that I always say in build and setup videos to remove the props (or not to mount them) when doing setup on the computer while having the battery plugged in?

I though I would do a demonstration video as to why you should do just that.

Charpu had his quad going bananas while doing throttle calibration. His story is very entertaining and a great reminder that it can happen to anyone of us. Watch the RotorRiot episode here:

Have you’ve had any similar experience? I would love to hear about it in the comments!

Air Bears – You can make a difference

Air bears is an absolutely awesome organisation dedicated to connecting RC pilots and local authorities to help in Search and Rescue missions of missing people.

It’s a volunteer based system. If you have a multirotor or fixed wing platform that you can keep on standby to help the local police or fire department in your area, you simply sign up on their website (there is a onetime fee of $25 to cover the registration process and you get a T-Shirt). You’re now registered on their global network of pilots. An online map will help the local authorities that need help, find the closes pilot and quickly get in contact. You can also help spread the word to your local authorities by giving them this brochure.

The goal of Air Bears is to have global coverage of standby ready volunteers to help reunite missing people with their families. If you don’t have an aerial platform that you can have on standby you can help out by donating to the cause.

New shipping calculating system

We’ve just installed a new shipping calculationg system which is going to be more precise than the old one. This means that you can now in most cases add more stuff before the shipping cost rises!

We’ve also updated the shipping costs to the new prices we have from PostNord for 2016.

If you have problems with the shipping options (most importantly, if you get the message “no shipping options available”!) please contact us by posting a comment below or sending us an email.

 

TriFlight Setup guide

Thanks to the fantastic work of Lauka and everyone on the forums, we now have a specially tailored firmware for tricopters dubbed TriFlight!
The new firmware vastly improves the flight performance of the tricopter as it features a ton of optimisation specifically tailored for tricopters. Among other things it features a custom in-flight adjustment for the thrust to torque factor of the powertrain as well as a equal yaw rate algorithm to get the same yaw speed in both directions.

The setup for the Tricopter V3.5 and the MiniTricopter is now made even simpler as the firmware is already pre configured with the correct PID’s and settings for the recommended electronics.

If you want to join the development, there is a +40 page forum post where this firmware was born and polished by our fantastic forum members. By tricopter pilots for tricopter pilots. Together we are strong!

If you want to print or cut your own Servo Setup Tool you can download the STL and SVG file here. Be aware that I have not tested if this file prints correctly. The file was designed by trial and error on my laser cutter. The file might need adjusting to get perfect 40° deflection.

Mini Tricopter back in stock!

The Mini Tricopter is finally back in stock! All backorders was sent out yesterday. Thank you for your patience and thank you for all your support. I really appreciate it. The Triflight code is coming along very nicely and the tricopters are flying 1000% better than the stock code. Hopefully we’ll move out of the beta and release the a v1.0 of the code in a not too distant future. Thank you Lauka for everything you have done. Also thank you to everyone else on the forums that have helped develop and improving on the code and providing feedback. Together we’ll soon conquer the world, ehm I mean the race tracks.MiniTriSnow

Servo setup tool and single frames

Tilt setup toolQuick update on the store; Added a servo setup tool to make it easier get the perfect center and exact 40° throw. Very useful in the setup of the Triflight setup. This will be included in the Tricopter and MiniTricopter kits from now on, or to be bought separately. Those that are waiting on their backordered Minis will get one with their order. The backorders will, incidentally, be shipped tomorrow!

Also added the option to buy the tricopter frames separately, in case you want to upgrade just one frame or accidentally destroyed one.

Pimp my yard

Pembroke wing

A couple of weeks back I heard from a friend of mine that the Swedish Rescue Training Center in Skövde was going to close down and that they were holding an auction for all kind of cool stuff. I immediately jumped on the interwebs and found the auction. Among the thousands of very mixed items such as firetrucks, CPR dolls, miniature models, projectors, chairs and such I found a Hunting Percival P66 Pembroke C.Mk 52
