Offshore prop for Neu 1521/ 1.5D?

[LuckyDuc]

Anyone have some suggestions on a good offshore prop for the Neu 1521/1.5D and 2 x 5000mAh packs in parallel?

Would a prather s220 be a good choice?

X447/3 or X450/3
X646/3
X645

These all work excellent with the same set-up listed. I assume its a V.

Smaller props will yield longer runtime. The 220 will also work pretty good.

It is a V. It's a DF cyberstorm. I considered the props you have listed for p-mono heat racing, but I was concerned about using them for 4min offshore heat racing.

OK, Try a 440/3 or a 215 would be my guess.

I run a x450/2 detongued and backcut on my DF33 1521/1.5d, 4-5 min runtime and temps are fine. I've also used a x447/3 detongued and backcut which worked well too. I don't race, but the runs are w.o.t. almost the whole time.

Thanks for the input guys.

Yesterday I ran a 1521 1.5d in a 31" Rico. Prop was a backcut M447 with a little cup on the edges. I burned 7000 mah in a four minute run. All temps were under 125 degrees.

Awesome info! Thanks for posting the mAhs consumed in 4 minutes. That will give me a better idea of where to start when I get mine done.
