Hello all,
I am fairly new to this RC stuff. I have been flying for about 4 months now. There is something that has been bothering me. It seems that the planes are always way under powered compared to the review videos. I live at just over 4,000' msl. I think the altitude difference is killing these suggested setups and stock motor combos. Is there a rule of thumb to use for us high altitude flyers for choosing a motor?
An example is that I have a YAK 54 that came stock with a 700kva motor at 110W and a 11X4.7 prop. The plane could barely keep going fast enough to not stall. I have a NTM Prop Drive 1000kva at 235W with the same 11X4.7 prop and the thing will actually climb vertical now. The demo video shows this plane with tons of power with stock set up.
I guess my real question is... I have been thinking of building some of these Flite test planes and I'm worried if the performance will be the same. Or will I have to put such a big motor on that everything is going to be out of balance etc.
Any thought would be great!
Thank you!
