Use unleaded gasoline with a minimum octane 95 mixed
with synthetic oil designed for two-stroke
engines.
For running we recommend 1:25, after running 1:30. Run-in should take about 2 hours of operation.
We recommend Valvoline oil - SynPower 2T - Full Synthetic, Mobil 1 - Racing 2T - Full Synthetic or
Repsol - Moto2T Racing. If you are not sure about the suitability of oil, which is going to use, contact

4. Propeller
With the engine FM 170 B2 - FS we recommend the following propellers: two-blade 32/12, 34/12.
Three-blade 30/12, 30/14.
For best results use Fiala propellers.
With these propellers motor should be measured on the ground to achieve optimum speed, ie
approx. 4500 - 5000 rev / min. When installing and using the propeller observe strictly all safety
recommendations propeller manufacturer. Propeller is mounted on motor by a central bolt M10x 1
and six screws around the perimeter of the flange.
