RE: Coolpower Heli 20 same as Pro Pattern 20?
I spoke with the folks at Morgan fuels today. He said the web page needs to be updated, the Heli 20 has the same oil mix as the heli 30 (22% low vis), thus different from the pro-pattern 20. He said it may smoke a bit more. I ran some today and after re-tune seemed ok but somehow different than the pro-pattern 20. I think I'll use up my heli 20 and go back to pro-pattern 20.
