which engine to use
I am new in ΒΌ scale acrobatic aircraft. I have just bought an EXTRA 330 L with a wingspan of 2.00 m. The manufacturer suggests 40-50 cc. gas engines. I want to power the plane with an MVVS, can the more experienced pilots in this forum please advise me which engine to use, the MVVS 45 MG with 5.2 bhp which weighs 1400gms or the MVVS 58 which has more horse power but is 400gms heavier?
Any replies will be well appreciated.
