I had my plane crashed which was P51 Mustang PTS of Hangar 9 due to Rx failure, Rx was JR R700 slimline which came with the combo and Tx is still Im using JR XF421 EX after that I used Hitec's Electron 6 Rx, never had any problem with that, and I'd also prefer Rx of Hitec. I'm also using Hitec's HS311 servos, never had any problems with that. Hitec is comparatively cheaper in price than JR but performance wise its really great. Never had problem with it.
