RE: Roto 25
I have been watching this thread for a while and taken bits of advice from many. i mounted my Roto 25 in a 1/4 scalt balsa USAFokker D8 picured here. Performance is spectacular, engine is smooth and power plenty for this 13Lb model. i used a steering arm for both throttle and choke, mounting the servos for both on the firewall. no interference issuse. i am spinning an 18x6 simitar prop which looks great and runs well. This is a fantastic engine. i am buying another one for my next scale project. i will then own two.. maybe a twin is in my future!!!!
