Okay, I have read through the instructions for the ES 40 and determined that is what I will build this spring. I have available to me OS 0.50 SX with Tuned Exhaust and all of the building supplies necessary; what radio do you suggest for a beginner. Could someone suggest a radio to use, I have had experience with a JR XP7202 and found that I love it. For those who are not familiar, it is a 7 channel transmitter with channel synthesizer and all the tweaks I could imagine. The only problem is that it costs $300 with receiver and servos, I do not know if I can hack that much cash, any other suggestions. Lastly, for any body who has built this kit before, any suggestions on approaching an building it.
