Nick, when I decided on the Spitty 5055-390kv motor, it was based on me liking the SK3 5055-430 (which I can't get at the moment) with 14x8x3 props for the 17 1b A-26. I'd have no qualms running that power train again for the 335. As the 335 will significantly lighter and less draggy than the A-26, that power train should do well for the 335. Plus, this power train was no pulling near the wattage that the motor could handle. Unfortunatley, the SK3 5055-430 wasn't available and the next closest I could find in that size class and kv was the Spitty 5055-390. But, increasing two inches in prop diameter should result in a power increase (intuitive assumption, based on one data point). It does concern me that the Spitty is running this motor with a 16x10x4 prop; so, by dropping a blade, I'll be giving up some power per motor. But, I'm doubling up the motors. So, again, in the absence of experimental data, I expect the power of the motor with the MAS 16x10x3 prop to be good for the 335. One day this week, I'll put the 5055-390 and MAS 16x10x3 on a wattmeter to see what it actually does. if I were to decide to go down an inch in diameter, I believe that the power output would still be good. I'll also put a MAS 15x9x3 on the motor and see what the wattmeter says. Unfortunately, I stopped by my LHS today, hoping to pick up a pusher MAS 15x9x3, but they didn't have any in stock. I hope that MAS offer a pusher 15x9x3; I haven't checked yet.
Another set back... My LHS had some TruTurn spinners on the shelf. I grabbed a 3.5" 3-blader spinner, which fits very nicely on the MAS 16x10x3 Tractor Prop, but very unfortunately, the friggin prop shaft on the Spitty 5055 is too friggin short for the spinner/prop. UGH! If it weren't for bad luck, I'd have not luck at all. Gloom, despair, and agony on me.
