Fuel for R50

[fayrwerks]

i heard from some fixed wing flyer that you can run methanol/castor oil on bigger os engine. can i run the same mixture without nitro (4:1 Methanol/castor oil mix) with .37 os or tt50pro engine?

[Jafa]

Those engines are not designed for zero nitro
They will run and be usable
they will not produce the power they are capable of
and they may be difficult to tune...

Get a Webra if you want to use zero nitro
