Only had one MA prop. Never again. Far too flexible. I want the engines energy go into accelerating the air not bending the prop.

I virtually exclusively use APC, but trying Bolly clubman at the moment as well. Seems very similar to APC.

I tried a 13x6 on my Laser 70. APC gave rpm about 10,000, MAS gave about 9,000.

Also noise reduction is a big issue in the UK. MA and Graupner tend to be a lot noisier than APC of equivalent size, even given lower rpm.
