I'd like to sport around the lake in the high 50's =). Running 4s2p 5050mah, Hydra 240. Prop suggestions are much appreciated, thank you.

I run 1521 1.5D's in both of my P-Monos on 4S2P 5000 mah., one with a Hydra 240, one with a T-180. They weigh a little over 9 lbs rtr, and use a 450/3 . The setups are for heat racing, low to mid fifties; only maybe 2.5 minutes and the motors barely get warm. The Sprintcat should pull less amps, but more runtime for sport running may require a less agressive prop.

That's really good to know...I have a 20 Sprint cat as well, but it is setup for nitro right now. Eventually I will be switching it over to FE with the same setup you have.
Great prop advice Tony!! Hope you are having good luck at the trials this weekend!! Let us know how things are going (or how they went)....

Thanks bro...Comment

I thought about that too, I figured the S230 (similar diameter and pitch) would be a rocket but it just didn't have the stink. You think strut adjustments for larger 2 blade props? I've had better luck running 3 blades in cats than 2 for some reason.Comment

I think the 455/3 would be a bit much, a x452 x455 is what I would try next, before that big 3 blade.
whats the strut setting up now?Comment

whats the strut setting up now?[/QUOTE]
Strut is set at 5/8... recommended setting for the higher RPM of the 1515 1Y, I don't know what's recommended with the lower kv 1521. The 1521 is a new motor for me and this cat, I look forward to testing as I think there is lots of room for it with this set up. Any recommendations are appreciated and welcome =). Where in Colorado are you exactly?
