RE: RCD 26 CC Gas Engine from Hobby King
I bought two of the FTL26s which are the piston ported version of the engine. It's very smooth, runs well, not super powerful:
Xoar 16x8 7740 rpm, 2200 idle.
Xoar 17x7 7200 rpm, 2050 idle.
MA 16x6 8200 rpm, 2000 idle.
Trgy 16x8 7500 rpm, 2000 idle. Turnigy is a laminated cherry prop.
My G-23 with the same 16x8 Xoar turns 8200 rpm idle 2100 rpm.
I think it's a keeper, but you won't get support from HC. Keep in mind these are really simple two stroke motors, and you have help here on RCU if you need it.
