Could you guys give me advice about good engines?
Here in Portugal I can find mvvs. Are they good?
For the money you pay for them I think they are really good (2.5 GFS/R-ABC@63€, 3.5 GFS/R-ABC-RC@67€)
Are there better?
I'm thinking about building a speed plane, like those that der_steuermann has shown in 200MPH thread
but put in it a "sport" engine with rear exaust...
I've also seen the novarossi RS12F... 1.35hp@40000rpm, Practical Range 6.000÷ 46.800 rpm[X(]
but where to buy this thing? and how many €€?
