    Finally got a chance to give my gimbal a go today. Overall I’m pretty happy with it. All the settings are stock, but I did turn down the gimbal motor power a bit on it.

    This was just some line of sight flying and testing. It still needs some tweaking here and there but really its not bad at all and even though its fairly heavy, it still flies quite well. You can notice the weight so if I continue with this setup, I will likely get some larger props.

    When the front arms are extended, just double check that the two screws used to set the tension are actually snug up to the two frame plates. I know I had one of mine just barely loose even though the arm felt good and snug but that loose screw had enough room to vibrate and make some very annoying sounds.

    I’ll also be trying the sunnyaky motors in the near future as two of my three ntm had really bad bearings. I’ve replacement bearings on route first to try though.

    Great flying, love all the low and fast stuff

    My issue was just the bearings. No issues with slop. I’ve got replacement bearings coming and I’ve bought enough to do a good few motors. I would potentially buy them again knowing I’d have to likely change the bearings in some of them. But again would potentially just buy a better quality motor. Depends on budget I guess.

    Here’s the perfect gimbal, lol.

    The weather has been rubbish here too. Today looks really calm, but of course I’m away from home! The next week is looking promising.

    Looks like my gimbal board is slightly different to yours. I only have prongs for pitch and roll. But easy enough to sort. I initially was powering the gimbal from a separate 3s lipo. Would I need the ground wire then along with the signal wire for pitch control? I’ll just try it out, or may just power it like you have at the moment. I won’t be using the gimbal too much as it’s too heavy. Would be nice to get a light weight one like you have there.

    The gimbals Chris and I are using are complete preassembled ones that we purchased.

    I picked mine up from goodluckbuy for about 55 dollars.

    Nicely done and some good looking footage. I’ve only managed one quick test of mine so far due to weather. I did noticed in mine, and yours a bit too that the tri does a slight “tail wag”. Not sure how easy it would be but I think this could be tuned out through the FC with some experimenting and patience lol.

    I still have the rubber mounts on mine and didn’t notice much for jello. But again, it was such a short test so I need more footage to check. I know you took yours off because it was adding te jello effect. It could be the different mounting positions between them. Have you tried mounting it directly to the battery tray without the cushion to see if the anti vibration wires soak up any vibrations?

    I see you have the manual pitch control setup. I was attempting to do that but everything I saw on YouTube was using the Dji controller so wasn’t sure what I was doing. Care to share some insight on how you hooked it up?

    Thanks fellas for both suggestions. I may very well order some bearings first and just replace them in the two motors for now. And I have some good motor options if I choose that route later on now. Thanks.

    Here’s how I currently have everything laid out.

    Hey Andrew, your case pretty much sounds exactly like my case. It closes nice and tight on the corners but right at the handle there is a gap. And yes, a good bit of force to close it. It has it’s flaws, but I can live with them. The case itself is tough and rigid. Overall I’m pleased with it. I ended up cutting the included foam also. Added a bit of thin foam(3/4″) on the bottom to keep a bit of a buffer still. It’s all nicely packed in there now. Tricopter, spare props, fatshark goggles, 3 batts, and a few other bits too. Will cut a spot for the gimbal shortly. Will get a pic up tomorrow.

    I’m by no means an expert, hardly an amatuer in my opinion. But I’ll try to simplify the purpose of a BEC if that’s what you’re asking. And more so an external BEC as opposed to one built into an esc. Although they are very much the same.

    Essentially a BEC is used to regulate the power(ie. volts and amps) from a battery to something like a receiver, servo, flight controller, etc.

    For example; let’s use a tricopter. The tricopter needs to power things like the flight controller, receiver, servo, and video transmitter. If you are using esc’s without built in BEC’s, you need to power these items, but obviously can’t do it direct from the battery for most. A servo generally needs between 5-6v, receiver the same, etc.(vtx can likely go off the battery, but that’s besides the point). So with an external BEC, you can tap into the power from the battery and it converts the power to say 5 or 6 volts which matches the requirements of your equipment. Now all these items together will also draw an amount of amps. Just for sumplicity sake, let’s say the servo, receiver and flight controller all draw 1 amp each. In that case you will need a BEC with an output voltage of about 6v and at least a continuous 3amps. Make sense? Hopefully.

    Again more specific to what you may own if you bought David’s recommended gear. I believe the esc’s have a built in BEC that is about 5v and 0.5 amps. With this setup along with the kk board, they all are enough to power the FC, receiver, and servo when setup as he advised. Now let’s say you then also want to charge your gopro camera while flying. Now the amps that the esc internal BEC’s provide is not enough to also do that. So what people will do is buy an external BEC(with sufficient specs to meet their needs) which takes power straight from the battery, converts it to the correct voltage and provides enough amps to power all the existing items plus the gopro. That essentially sums it up in simple terms. I think.

    Please correct me if I’m wrong and be aware it is simplified.

    Sweet indeed!

    Thanks for checking that. Is it just the naze board or is there a general PDB too?

    Do we know roughly when these will be available?
