It is normal to tilt a little, but 40deg sounds excessive, even not possible. The range of my tilt mechanism is probably around +/- 40 deg. This would mean that you would have no authority yawing one way. Pic will be good, yes.

Not sure what your question is. What is the sense of rotation on the props?

[biggestRCEfan]

From what I can see from your video your LH prop is upside down, not producing any lift. That’s why your RH side is lifting (as it is upside up ..). Check all your props for correct installation and correct rotation. Should work. My setup is very similar and flies great – better on 4s. Although I have RCtimer 9×5 props (9×5 is recommended for the 4s setup). You may want to look at 9×5 on 3S, which is recommended on 1100kv.

Is there a risk to my integrated naze32 if I use 1.10 as opposed to the 1.9 on the RCE build page? I understand the 180 pitch alignment adjustment.

Had trouble trimming my tri. It was drifting backwards on me and no amount of acc_pitch_trim would correct the problem. Then I discovered that the accel calibration was the issue. I had the tri sitting on a level surface, but due to the vertical panels of te canopy extending below the bottom plate at the nose, it was actually sitting nose-up by 1.6deg! This was sufficient to cause my trim issue.

Lesson: Make sure the Naze frame is level when calibrating!

@wynnsquad, I had a similar incident. I did a lot of shallow dives, accelerating to the other side of the field, 180 deg turn, nose down and full throttle to first stopt the movement in the original direction, then accelerate and shallow dive to the other side of the field, and then repeat the sequence. It was a lot of fun, but once, just after take-off, I put the nose down with full throttle to accelerate and climb, heard a “snap” sound. From about 3 meters high, not very fast, it rolled left and forward into the ground.

I found it with the left prop with one blade snapped at the hub. Not sure, but the only explanation I had was that I had a fatigue failure of the prop due to the high loads I put on the props by the accel/decel maneouvres I was doing.

Any similar prop damage on yours?

So, finally I was able to reflash my esc’s to confirm that this didn’t solve the left motor stuttering problem. I bought a replacement esc, soldered it in place. During my first run it appeared the problem has shifted to the tail motor. But then I noticed that if I give enough power, all three would start normally. [Is it a problem if all motors don’t start spinning at the same throttle setting? Esc calibration issue?]

Because of the crashes I had with the faulty esc I flew a fair few batteries doing low-level and punch-ups to make sure all was good. Indeed, all seems to be good.

Thanks for the advice, @LeoTheHuman and others.

Thanks @LeoTheHuman. Once I have my RCTime USB linker I hope to be able to check FW settings and reflach all with same.

I went flying at the field today and can report that this design is indeed crash resistant. I did a few cart-wheels without any damage. The cause of the crashes I suspect is the left motor that suddenly drops out. During the last crash I could hear a motor trying to get back up to speed …

Did anyone have similar experience? Are there other potential causes?

I will probably order a spare motor and ESC.

Maiden flight of 31/100 today! Build went well and first hover was predictable in angle mode.

However the left motor needs help to get going. It stutters, but once it is running it behaves. After 3 minute flight both the left motor and esc is noticeably warmer to the touch than the other two. Is it the motor or the esc?

I’m running the electronics kit bought from the store, on a 3s battery while I wait for my 4s.

I started to fly tricopters with Naze 32 in acro mode. It is very hard to do. I understand fpv racing is done best in acro mode, but when I started fpv I realised it is even harder to hover in acro mode. In total I have rebuilt my tri a fair few times. I switched to flying angle mode and then it became much easier. When I am ready I will attempt acro mode again.

This is before the crash …
