when i went looking about a year ago i could not find many ultimate for gas i found this one at http://www.bobflies.com/
its a 70.5" WS 77.75 lenght kit to build foam wing, turtle deck, rudder, and stab. its made for a 70-100Cc and i went the 100 route its power for days with a 100 on there. i am talkiing like 50-60 MPH up lines if you nail it. i fly it at 1/4 throttle for staight and level flying. i had to send my C & H in last week so its down right nw the sensor was going bad in there. a 70cc motor would still work great on this bird. now that are quite a few good ARF out there in the ultimate series. i think that was my last stick buld kit as if you wait long enough a manf. will buid the ARF u want. your bird looks great the 50CC is the motor popular motor and plane going right now.
