150cc outrunner in chainsaw ?

[speedy]

Would a hk 150cc eq outrunner notor be enough work in a cainsaw Or weedwacker on 10-12s lipo ?

I know they have 50cc versions but theese notors are cheap an have low effishnsy evel so iwas thinking that by putting in an oversize motor would make a more effishient setup .

What do you guy's think ?

O and if i whant to mount a outrunner per axels diffoinion shafts.!
How big and what kv would work?
