I have a dle 30 with about 1 1/2 gallons thru it. It starts and runs great, but here is the problem. It is prone to stalling when inverted or vertical. I am turning an 18 x8 at about 7800, just a bit below peak. I have checked and re-checked the fuel system and all is fine. It is the latest version with a rear carb. I would appreciate any suggestions. Thanks.
I'm assuming this is at or near wide open throttle (WOT)? I had one making me absolutely crazy for a while last season. Same thing, went through everything, incuding carb, several times. All over the carb adjustments. Dead stick landing followed any extended attempt at vertical climb. Then one of the fellow club flyers suggested I hold the nose of the plane up with engine at WOT, just like I did when checking a nitro plane. Well, that point out, with no doubt, the plane was going lean, though I thought I had the carb set up fairly well. Went a tad richer on the high speed and no more trouble.
Point is, I found though it's obviously much more difficult handleing a DLE30 powered plane, nose up at WOT check is just as necessary to assure proper performance as it was when checking a nitro plane.... FWIW
