My Posts This: Topic Forum | It's not probable to have a 180 degree phase shift mechanically. It would be much more possible if you experienced a 90 degree shift (i.e. rolls when inputting fore/aft pitch cyclics).
Was your headspeed low at the time? Did you have a blade-stall or near blade-stall condition?
The Evo can get the woof'n'poofs if the blade speed decays too much. I've had this happen twice now, and the symptoms look like a drastic cyclic wobble. If you keep your head, lay OFF the cyclics and back off on pitch it'll stabilize by itself. However, if you panic and start banging the cyclics you'll just aggravate the situation and end up in a crash.
For the most part I'm very happy with the Evo design. The model flies very well and is both stable and responsive. However I've been flying Kyosho models with TRAILING EDGE control for years and NEVER had a case of the woofs on those. Even if this only happens in blade-stall situations I'm not exactly thrilled. I guess all designs have their weak points and I do hope there's an engineering solution to this issue.
