You'll probably need a bigger pitch on that prop...I'd go with a 4.7...and yes, you reciever crystal has to match the transmitter crystal. Also, 3 cell is kinda heavy, but manageable, and jeti esc sometimes have malfunctions...I would go with castle creations...a phoenix 25...you can't go wrong with that...the tensor is a unique design...read up before maidening it. good luck
