Stunning plane!! sounds like that stab vibration could get interesting....could it be flutter? with all the tubulence off two wings?

Bla Bla

Regarding your earlier comment about unscrewing the pump on the OS140. Do you mean anticlockwise viewed from the back of the engine?

I really could do with a little more duration on a tankful as over here it is costing me about £3 to £4 per flight in fuel!!

My current set up is standerd header and hatori pipe with about 1/4 inch gap between header and pipe (Sorry don't know the length) OS F plug (fantastic move that!) and running on 18% oil and 18% nitro.

What fuel are you guys running as 10% nitro is sooooo much cheaper here. I'm thinking of 15% oil and 10% nitro and maybee unscrewing the pump 1 turn. Does this sound lik the right direction?

Thanks in advance
