As far as the reciver go with a berg it will save your airplanes it's 50.00 usd @ www.allerc.com

for servos get the gws pico those are my favorite cheap light and lots of torque for weight. you can get those at www.allerc.com

if you don't have an engine don't skimp here go with a mega 16/7/10 ask real15 he also makes custom gearboxes for them don't buy the mega or mec gearboxes go with his gearboxes the best I have ever used. I run his 3 to one on a 13x6.5 prop and it gets 32 oz of thrust at 9 amps.

But be sure to get a hold of real157 on ebay he will hook you up he did me his service is also great.
