Using a APC 16x8 I got this;
1700 idle-good 5800 wot transition very bad, almost non existent glow always on, wouldn't run with out it.

Switched to 50% methanol/ 50% gas, 6% on lube and acetone yet. Too much lube I know, but it shouldn't be a problem when we use as high as 20% in them. Idle about the same, wot 6000. Transition better but still bad.

Went to a 14x8 wood prop. Idle about the same. wot 6800, transition better yet, but not any where's good enough.
Will run at wot with out glow driver, but not at idle. wot lost 500 with glow driver off.
