@Lauka, between the rain and shortage of help I didn’t get to filming it. Maybe next weekend. In the mean time I ordered an OpenLog which may be here by then. Looking forward to actually looking at the data myself!

[biggestRCEfan]

@lauka, pretty much yes. Will try to get some video this weekend.

@impulse, good points. However mine is smooth, no binding. There is a little play on the servo, but that should show up in hover as well. There is no yaw drift in hover.

Just came back. In accro I have same or maybe worse yawing. I didn’t fly too much, as I’m not proficient enough in accro to fly without damage … I just flew until I saw the yawing happening. @Lauka, what do you mean try in different pitch angles? In CF with the 3D model?

I fly with FrskY Taranis and D4-R2 in PPM. But as I mentioned before , in the original RCE FW I didn’t have this issue, so TX/RX is not in doubt.

Ok, I fly as yet only in angle mode, as I am just starting out. Nevertheless, the initial stock FW from David’s store didn’t have this issue for me. Flying LOS was a pleasure. I did increase the I yaw gain with no real effect. Sorry, I’m not at the black box stage yet.

I don’t have major difficulties keeping the nose straight when flying FPV, but I do notice sometimes that I fly a bit sideways. For me the yaw drift is much worse flying backwards than flying forwards, hence I have maybe less of a problem as @Frank (as generally I don’t fly backwards in FPV 🙂 ).

One thing that may give a hint though: after a major crash (described elsewhere on this forum), I rebuilt and changed one of the ESCs with a new one received from RCE. I had difficulties trying to configure it as it was FW 14.1 (from memory) with BLHeli bootloader. I softbricked it in the process. This meant I was not able to change any parameters on it. From what I remember seeing before it was bricked, I adjusted the parameters of the other two ESCs (such as damp light after having loaded the same FW). It is possible though that there are some parameters different between LH and other two motors, which could cause assymmetric behaviour. However I have not noticed any issue with fast vertical climbs or descents.

I will give rate mode a shot and see if it behaves differently.

Thanks guys!

Hi @Lauka, thanks for the work you are doing!

I posted my tailtune results. Have a few questions though.

Is this new 0.4 Beta 1 supposed to address yaw drift? From your description I think it should. However, pre and post tailtune I have similar behaviour. From a steady hover, flying forward, nose will yaw left slightly. From a steady hover, flying rearward, nose will yaw right up to 45 deg or so. This makes it very hard to fly LOS.

I have the stock setup including electronics. Post FW load the only changes I made was to configure cleanflight for telemetry etc. No CLI changes.

In the mean time I’m having lots of fun flying FPV! It would be good though to have the yaw drift issue resolved. Any ideas?

I had a similar issue once, but it didn’t fly, so maybe not the same. Anyway, I think I had the front props, turning in opposite directions, installed the wrong way around. I.e. the left motor turning CW I fitted with the prop that should be on the RH side. And vice versa. This meant that, if you don’t look closely, the front props are turning in the right direction, but producing thrust upwards …

Just something you could check.

Thanks mate.

Hi @GAntonjo, I am facing the same issue. Thanks for your help. Once the ESC is flashed as you describe, is it then possible to read and write via the signal line, or does this depend on CleanFlight being sorted out to not softbrick the ESC, as I managed to do with my ESC?

[biggestRCEfan]

I agree 100%!

Guys, my setup is stock RCE Mini, including electronics sourced from RCE. I have 2 2015.6 DYS ESCs (LH and rear) and 1 2015.10, all running BLHeli FW14.0. Naze3 FW is Triflight 0,3. Followed Leo’s setup guide, although I only did the tail servo setup by eyeballing it. The mid setting is set to have the tail motor vertical compared to the airframe, and the mid and max to have a symmetrical deflection from vertical. I etsimate it to be around 40 deg either side of vertical.

I fly in angle mode and the response with the stock PIDs is vry crisp. The one issue I have, flying Los, is that it yaws right when flying backward. By about 30 deg I would say. Going forward it yaws opposite direction, but less. This makes it hard to fly LoS, as you lose orientation pretty quickly.

I thought I saw some posts describing similar behaviour during early days of MiniTri flying, but can’t find it. Is this behaviour due to imprecise tail set-up? Should the ESCs be configured in main/tail or multi, i.e. Should the tail motor be different?

Thanks Leo for your guide!

[biggestRCEfan]

Yes. Radio control and tail motor should move in opposite directions.

Thanks @GAntonio! Life is hard when you have only mac … I run Win just for USB Linker/BLHeli … Anyway, I succeeded in bricking my single 2015.10 ESC I have installed by trying to update it to 14.2 using BetaFlight on the Naze32. After that attempt it does not read the ESC anymore. But it still runs. So I proceeded to update the other two with USB Linker to the same settings and with appropriate sense of rotation. Will see what gives.

I have triflight 0.3 no on the Naze32 but will not attempt to use it to program/flash the escs as per your other post.

Now I will have to figure out how to recover the bootloader via the process described by many but which would require some more stuff to be learnt and bought … As they say, building is most of the fun!

[biggestRCEfan]

After my crash I received the spares to rebuild. Two front arms, battery plate and a few spare ESCs. In the end I only had to replace one ESC. The new batch is 2015.10, compared to the problematic 2015.6 batch. So now I have two 2015.6 and one 2015.10. [The ESC was not the cause of the crash but was damaged].

When I did an initial power-up to check sense of rotation I saw that the new ESC needed to have its direction changed. Here enters the problem: although I could control the motors from Cleanflight, I do not succeed in connecting BLHeli Suit to the new ESC, while I am still able to connect to the two older ESCs. I use RCTimer USB linker. Any idea on how to solve this problem? My next step is to replace the ESC, but maybe someone has come across this issue?

Cheers
