![]() Chasing speed with this will encounter a sad panda face. High rates, this is a warm-liner at best, it's clear it is a aerobatic sport flyer. The stock electrics/setup seemed to handle 4s quite well, speedy and motor were only just warm after a few WOT passes. Also the tail surfaces were evidently twitchy and unstable at WOT, from either too much air speed or thrust from the fan? Hard to say.Īll in all, it was a successful maiden, it is a nice flying plane. The servos seems to be of good quality and I don't think the problem lays with them, its the length/size of the aileron plus it is still foam with flex. I don't think trying to strengthen the cavity with resin will fix the problem, the flex in the wing is not the issue, it's the lateral twist.Īnother problem I encountered was the ailerons at high speeds were showing huge amounts of blow-back, almost no response at all until the plane slowed. The wing itself shows strength with the resin/foam construction and the CF rod plus the glass strip but where the evident weakness is the cavity where the aileron servo is mounted. Down wind or up wind it would flutter aggressively. ![]() I have never seen wing flutter like this in my life, violent and I was expecting the plane to snap a wing or take a dirt nap. I had a friend hand launch for me, used about 3/4 throttle and it got up fine.Īfter all was trimmed out I tried a couple of high speed passes WOT. Started out with perfect CG with a 3300 4s, everything looked solid. I'm going to start this by saying, do NOT fly this on 4s.
