I didn't really change anything for the T-Rex 450 with RX2702V-D in the last few weeks. It worked before and suddenly it keeps spinning. That is weird. Anyway, I will need to dig deep into something else.

Alright, I believe it was a mechanical issue on both helis. I increased the tail pitch range and did a setup again on the RX2702V-D on the Hughes, now it works.

I also found out that the pitch range on the tail rotor in the V450D01, where I have the spirit, was too narrow. I was able to adjust it, so it just slightly spins counter clockwise. I will now change the tail rotor set with another one with bigger pitch range and see what happens.

ok, issue fixed. I exchanged the tail rotor system. I am now using the tail rotor system of the Walkera V18G01, which uses almost 500 size tail blades. The pitch range is much bigger on that tail rotor system. I could increase the limits in the spirit from 74 to 114 on both sides, so there is more leverage on both sides. And, now tail holds well even with lower RPM.

Thats great info!

Thanks for the update.
