I recently acquired a .60 size stinger with a os 91 fs max (60F carb, high speed and low speed needle). This is my third airplane and I'm having some trouble tuning it. I've been spoiled by having the relatively easy to tune LA .40 and .46's on my previous planes. Before I ask this question, let me point out that I've referenced all available guides in tuning, but I just cant seem to get it dialed in. It starts fine, but when I try to give it full throttle, it sputters and dies. Even when I seem to get it to a point where it will run, the thottle is very sluggish. Any suggestions on where the high speed and low speed needle should be set (I've tried the air blowing method)?
Thanks!
G'day Mate,
What size prop, type of glow plug, nitro content of fuel.
Have you checked the fuel tube inside the tank?
Make sure it is rich enough at the top end to increase slightly in revs, when the nose is pointed up, at full throttle, if so then it should be rich enough to keep running in the air.
