Hi Kelly,
Sorry I missed this.
I have the SAME issue with roll trim, I cannot get it fixed. At first I though it was my thumbs but after 100 flights I know better. Of course chopping the tails off may have had something to do with it, who know, it flies well enough.
As for Whidbey I am not going but several of my frineds from Los Angeles are, it should be a pretty big turn out from down here.
Regards,
Don't sweat it Matt,
I've since flown mine a few times, as seen in JohnVH's Whidbey photo threads, and the roll trim is much better but just not bang on. I'm gonna give up on fixing it, since I don't think its a servo thing any longer. I'm pretty sure it was partly servos earlier, but they're pretty well bang on now. I've heard form a few skilled Aero guys that it may have something to do with having fins that are too large, while being too close and above the CG. If that's the case, yours may fly better than mine... Its basically the opposite of dutch roll, where over compensating with extra fin creates a spiral dive tendency...
I know it won't track nearly as well as my HotSpot, but at least its enjoyable to fly now so I'll leave it as is... I've only got 15 flight on mine so far, but I can see a day when I'll want more than the 14.5lb of thrust I have now though. I'm surprised you still haven't tried a P-70 on yours! I'm tempted to play around with a 600R one day and over rev it a bit for a couple extra pounds, then see what kind of speeds I can get out of her on a data logger.
Hey Moe, I only run a single 1500 mAh 4.8V pack, although I check it frequently and recharge often.
