@pamera How does it fly?

[flacke]

Anyone have issues with the Mag not calibrating correctly? Mine is off by 45 degrees. Home arrow and OSD compass are not accurate so I’m reluctant to hit that RTH switch.

I have everything setup correctly in Betaflight now with the tail and it is flying nicely, no broken props! Thanks a lot guys!

I am having problems with my mag now. The compass is off by at least 45 degrees and won’t calibrate anymore accurately than that. The home arrow and OSD compass are incorrect so I haven’t had a chance to check the RTH function. Everything else with the GPS works well.

Also, I fly crossfire and my RSSI is bad. Dropping to 15% at about 1000 feet away with 500mW. My Immortal T is setup like swissfeek has in front bellow the camera. Any suggestions with that?

As far as the servo tilt limits are concerned; I have the servo limits programmed into my Tx not on the FC (if that’s possible). Could the FC be using max servo throws?

The props are breaking 14-20mm (3/4″) from the ends and no damage near where the servo is. With extreme flex using my hand I can not get the props to touch anything.

Props on motors 1 and 3 are breaking. During a turn to the right (cw) wouldn’t motor 3 (ccw) spin up to a high rpm to stabilize? That could be the point of failure where the prop reaches the highest rpm of the flight and fails? While the tail motor is tilted presenting a large target for the debris.

I have a few different props on order to experiment with. If it happens with another brand. I will do the crayon test and video the props. Thanks for your help!

I use yours! LOL. Thanks by the way.

Exact same break. They were the HQ that come with the LR, the shinny ones not mat finish. I ordered some MAS as suggested by Kevin_Erik. Here’s the video, props go at 27 seconds. As a testament to Gopro Hyper-smooth it definitely smooths out those vibes I was getting in the Runcam 2. FPV feed is nice and smooth and looked beautiful (I soft mount my cameras). I need to learn how to fly this thing, but when I do it’s going to be so much fun!

The same thing happened again today with the other set that came with the LR. I thought the same thing initially but there is nothing to hit and no damage, scuffs, nothing. I plug in the XT60 under the trailing arm so there is no slack there and the balance connector is to a voltage alarm on the frame. I would believe however that one prop took out the other. And, that CW prop that has a mat finish to it is still perfect. It’s the shinny ones that “failed”.

Well guys my props exploded on my maiden flight! I noticed the ccw and cw props have different finishes from each other. ccw shinny and cw mat. Both cww exploded! cw was fine.

IT FLIES! It flies nice and smooth. It was a little breezy and my backyard is tight. I had no problem keeping it at a safe distance and away from the obstacle course in my yard. I’m going to have to practice a lot and buy a bunch of props most likely. But wow. FPV feed was jello free too.

Anyone have a sim they can recommend for a Tricopter simulation?

I’ll get my GoPro on it and post up a video in the next few day.

Can’t Thank you guys enough for your help!

OK got it. The Motors are correct and spinning in the right direction. I’m just not understanding the lack of throttle control like demonstrated in my last video.

I have been following Joshua for quite a bit. For FPV stuff and more recently setting up my Taranis and Crossfire and now Betaflight.

Since I’ve always had full control over my airplanes motors and servos the automation coming from a FC makes me a bit nervous. Seeing my throttle slowly ramp up and not responding to my inputs I guess is a case of not having props load torque on the motors and confusing the FC?

[flacke]

I just want to say thank you guys for you all helping me out here with your speedy replies and information. I really appreciate this.

Ok. I changed the motors in CLI and confirmed in a dump file after reboot. I have a new video of the Motor tab in Betaflight if you guys could check it out and tell me what you think of it before I put props on it again. It just seems weird to me the way the throttle ramps up and then become unresponsive eventually. Thank you all some much once again.

Alright I got the correct Blheli32 suit and was able to reverse the two motors so they are all turning the correct direction. I also figured out how to write the rest of the Diff.txt file in CLI so that’s been done to. I put my props on and gave it a try today. OSD looked good and I had 7 sats in my backyard. I armed the LR and the props started to idle. Then with the tinniest amount of throttle it violently flipped itself over as if I had punched it. That was in Horizon mode. Then I tried Stability mode and when I armed it the motors idled with small pulsing at zero throttle input. The smallest amount of throttle again flipped it violently. When it’s on the bench w/o props one little “click” of throttle make the motors slowly ramp up to full throttle. Betaflight receiver tab and the preview all look good and behave as they should.

Any ideas where I go from here?

[flacke]

Thanks for the response! I haven’t put props on it yet. It seems like after a little playing with the throttle the throttle stops responding so I didn’t want to do that. I do know two of the motors are spinning in the wrong direction and I wanted to reverse that in BLHeli32_Suite instead of by wire swapping. But, I can’t get that to work. The program connects and sees the ESCs but I can’t flash or write any changes. Each ESCs is labeled b,b,b, and the write function isn’t functional. Do I need to use the DShot thing I’ve read about to flash firmware to the ESCs?

Also, I read Clauds Diff.txt file to changed the PIDs but I don’t understand what the other info in that file is. Should I be changing other settings besides the PIDs? Thanks again!

One more thing. In the video you can see the servo is functioning but eventually stops centering after it’s been moved. I know it’s friction free and not binding. Is this all because there are not props generating a load force?

[flacke]

Hi guys. I’m a horizon hobby flying fixed-wing “pilot”. I’m new to multi-rotors, Betaflight, crossfire and OpenTx. I just built my LR and flashed it with Betaflight 4.0.3 firmware supplied by Jihlien on this forum. Fired it up and am having unexpected behavior. When I arm it the motors start spinning right away with no throttle input. Then after several seconds of playing around with controls, throttle become unchangeable and strange vibe noises at particular stick movements from a particular motor start.

[flacke]

Good to know thanks for the reply. I’m just finishing up the build and about to get into the software part, that I have zero experience with so I’m dreading all that. Wish me luck!
