The manual says to use a 10x4.7 prop with the Towerpro 2408-21. But personal experiecne has me seriously doubting the motor can handle that on a 3 cell. To further compound the issue, a reviewer on budgetrc.com mentioned that he used a 9x4.7, which is still outside the range of the motor, according to headsuprc's very in-depth motor info.
So, what say you, owners of the ULD?

I don't own a ULD but I do have several 2408-21's and yes you will burn it up running a prop that big on 3S. It does good with those props on a 2S...that is how I use them.
