RE: RX questions
If you have a receiver for electrics, and the short range issue, you'll have to get another receiver for nitro. Since you're flying a 4 channel TX, a one of the least expensive receivers to get is the Berg Micro Stamp 4 channel. It's a full range receiver and will work fine standard size J-plugs. Best of all it's about $30.00 + $7.00 or so for the chrystal through Tower.
