Hey fellow v5 users---and perhaps the subset that fly the Logo 400. I've put v5 on my Logo 400 minivbar (and the L500 but don't have this problem). It's got a lot of great attributes---really connected and fast. But, at high speed...say a big sky backwards loop...and as I pull out, the heli porpoises.

Jan Matrosek was saying he saw that some with his 600, though I didn't see it and I don't know if it's as pronounced as mine.

Anyone else have this issue?

Thanks,
Tom

Only time i have seen that is A) you reach aerodynamic limits
or B) cyclic gain in setup under swash (expert hat) needs to be set to maximum value without binding noramlly between 75-95

I did this mod to my 400 and use stock mikado tape.

It's not porpoised before though I may be flying it more aggressively given how well the v5 works otherwise. I'll try turning up the cyclic gain.

Thanks,
Tom
