RE: World Models 27% Ultimate
My main tank is a 26 oz dubro although a much bigger tank would fit. I use a 3 line set up on the main tank filling the header tank with a tee first and then the main tank. I have flown the model for about ten min and have about a third left. I am also using an on bourd glow with a single 3000 ma battery to drive the system . The on bourd system only works on motor trim as usually the saito without it wont idle and reaccelerate without stumbling for long. The model itselfe has to be pulled in to land as it drops like a brick if alloud to idle for a long distance hence a fast idle is a must.I too have had this motor sitting around for many years waiting for a plane and didnt want a spacewalker or decathlon as times have changed.
For youre new motor how about a Hanger 9 extra 260 it seems to have a good wright ups.
