Well, we've had really nice weather today, so I took my Slow Stick and my Quad out to the lake front park this afternoon. After depleting the SS battery, I busted out the quad. FINALLY got to do some flying on a calm day in a big open space.
With the lower wing on, and wing extensions, it just handles ridiculously. Going straight its fine (though you can't get it to go down if you have any throttle at all), but in turns its just too messy, easily rolling over into a dive. So about half way through my flights with it, I tore the lower wings off. It does much better with just the upper wing, lift is not a problem at all. In fact, I think it may still have too much, and I think I'm going to trim down the wing extensions some more.
With just the upper wing I had a blast flying it around. Despite the excessive lift, it's quick, and you can do some cool tight turns. Even got it to barrel roll a couple times (though not necessarily on purpose

). It's also easy to find the edge of radio range, I had to work to keep it down low enough and close enough to keep in in range.
Tried with and without a dime in the nose. Everytime I put the dime in (with and without the lower wings) flight seemed to suffer. It seems to be pretty well balanced as is; guess the dual batteries and elec's balance it out. Looking forward to more flights with it
