Everyone and their brother are going to tell you something different on a thread like this that's common sense. Your best bet is to search the threads and based on the majority, use that info to help in purchasing your plane/supporting equipment. Anyone with any sense will tell you to buy the best you can afford-especially in servos, RX, batts. etc. so you only buy once and can transfer those things to other future planes. I personally like the Hitec 7955TG and use them throughout in my Extreme Flight 88" Yak-they will power anything you may ever want to fly. If you buy cheap, you will be buying twice most likely. As far as the plane goes, 50cc should be 84"+ do yourself a HUGE FAVOR and forget about the "betweeners" such as the Hangar9 260 mentioned above and the Great Plane performance series Yak, Sukhoi, Edge (the Ultimate is really nice though) as they end up with a high wingloading. Many people claim how good they fly but those very people have never owned an Extreme Flight plane, PAU, Wildhare etc.
