3w engines
3w are very good engines with a lot of power you have to be patient with the break in procedure.
They are not the lightest on the market if you compare it with BME or ZDZ but they are very strong and very well made.
I'm running a 42 on my Sig Sukhoi and I'm very pleased with it you will not be dissapointed you made a good decision buying it.
Happy flying.
