Thanks.. what length hors are you using to get the recomended 3D rates? will a 1" be enough. in the manual its like JR part#blah blah.. that is great but some of us cant afford the gold plated JR servos (wish i could). but i do have a JR radio though.. i will be using HS-645MG all the way around running on 6v KoKam 1500 Li-Po.
