Combination works well but does result in a nose heavy airplane. Mine came out at 15lb plus -- had to put about 8ozs of lead on tail.

I broke mine in using Wild Cat 15% sports fuel, about 64ozs on the ground. I burned another 16ozs of Tower Hobby 15% sport fuel cut with 50% of pure methonal. Idle was good. High-end was very good, and transistion was smooth.

Unfortunately I inadvertantly allowed it to run dry of fuel. It fell like a rock -- did not have enough altitude to angle it back to the field.

My new plane will get a Moki 1.80 instead.
