I'll be seeing you,


How much total time have you got on your .77 (the engine stabilizes and reaches its full performance and reliability, after 8-10 hours. That is 48-60 10 minute flights.)?

How was the break-in performed (according to [link=http://www.rcuniverse.com/forum/Tapered%2DBore_Engine_Break%2Din_%2D_Upgraded/m_1850473/tm.htm]this RCU thread[/link] is best)?

Do you use 20-22% oil, at least half of which is Castor oil, with no more than 5% nitro (Sig Champion, or PowerMaster GMA, or others, if you don't like to mix your own)? No, you can't use fuel that doesn't comply with this, unless you installed an extra head shim and then you can raise the nitro to 10-12%, but the oil must be as described.

Does your engine have the newer carburettor (send close-up photo(s))?

How do you adjust it?

Is you tank at the proper level (fuel jet) and fully isolated from any part of the airframe, with latex foam?


I hope this helps.
