My MVVS .26 momentarily sags when any load is applied such as turns, loops, split-s.
The eng is on a battlefloyd. Five other modelers have the same setup and don't have this problem. I've check the clunk and fuel lines. The sag is so brief that I don't think it's fuel starvation from the tank...maybe something to do with the carb.
Any suggestions...these guys are really eating my lunch.[:@]
