bobby, yes i am running a Vess 27a on a DA100 in a 32lb toc yak. i tried several props and the menz 27-10 worked the best until i got my hands on the Vess prop. the 27a spins up faster and helps the heavy plane out of a hover much better. it's seems to be alot better all around. now if i could put the yak on a diet and loss a few lbs it would be great.
