Guys, if you want a good flying airplane that actually flies like a pattern ship, one that isn't overweight and snaps when you don't want it to, is well constructed and fairly inexpensive, may I suggest a Northeast Sailplanes Samba? I fly mine with a Hacker A30-12Xl, APC 14x7E, CC 45, and 4S2P lipos. I pull about 41 amps at full throttle and have over 500 watts on hand. Yes, I know this is way over the specs on the Hacker but I only use full throttle on the verticals(unlimited, by the way) and the rest of the manuevers are done at the low 30's. I fly until I get tired and put back 1506 mah into my 4200 pack. How does the Samba do it? It has a NACA 9% wing and doesn't need more than that to fly well. It's also light weight, coming in @ 49 ozs. I added a carbon fibre LG and some wheel pants to spice it up some but the stock gear is ok. I have flaperons but it lands slow enough that I haven't used the flaps. Best of all, it's on sale for $139.95. (No, I don't work for them and I don't get kickbacks). If you are like me, I got tired of wasting money on ARFS that just don't fly right are too fragile. Most ARFS that were intended for glow and converted to electrics are too heavy for good pattern flying.
Just remember, if you use my power system, you do have to use the left stick!
