Sportflyer-RCU;
I've installed an OS91 FX, with a 13X8, and added 4.0 Ozs on the tail. fixed LG, Hightech 605 BB (High torque) servos for the Elevons, It has decent speed. flies great!
Had a problem with over controlling the stearing, I found that the endpoint should be set to no greater than 75% of the servo throw, otherwise the wheel trips-up in a turn
Total dry weight 7lbs 14ozs. Top speed 83mph
