Fuel
Always use unleaded 95-octane petrol mixed in the proportion 40 volume units of petrol to 1
unit of Mobil Racing 2T oil. If necessary, quality brand-name synthetic oil intended for
racing two-stroke engines can be used too.
For running the engine in, please use MVVS Racing 2T oil that comes with the engine. Mix
it in the proportion 30:1.
Never use inexpensive oil developed for garden appliances or synthetic oils intended for the
operation of methanol model engines. The manufacturer declines all responsibility for all
engine damages arising from the use of low-quality fuel.
Store fuel in containers designed for this purpose. Do not use mixed fuel older than 90 days.
Assembly
The engine is fastened to place by four holders built in the crankcase. The engine can be
mounted directly to the firewall or an assembly kit can be used (special accessories). Use
screws M6. If you decide to fasten the engine using flexible motor mounts, always choose
parts with enough solidity and strength. Make sure to secure the screws against loosening
and regularly check that they are tightened up and in good condition.
Since air is used to cool the engine, sufficient air circulation under the cowl must be
ensured. Never forget about hot air outlet – which must be bigger than the intake one. Gas
engines heat up to higher degree than methanol ones!
Do not forget that the engine needs oxygen from the air to be able to operate. Therefore
ensure access of air to the engine intake as well. Caution: intake of warm air from beneath
the cowl may cut the engine power output.
Caution! When mounting the engine in the model use seals to protect all openings and
prevent the pollution of the engine’s inside with sawdust, residual abrasives etc. Make
sure that the inside of the fuselage is clean and that all parts are tighten in place and
cannot be sucked inside the engine.
Exhaust
Use only factory-made exhausts pipes designed for this type of engine. Preferably MVVS
exhaust system, which also guarantees the announced power output. The manufacturer
declines all responsibility for all engine damages arising from the use of improper exhaust
systems.
When mounting the exhaust follow the manufacturer’s instructions. Make sure to secure
sufficient cooling of the exhaust.
