Hi,

Any recommendations for a brushless single shaft on the Perkasa 49"  and 39" versions?

I am using a Leopard 3536-8 Turn 960Kv motor. Currently turning a 45mm 2 blade 'S' pitch plastic prop. I have run it on an 8.4v NiMh and in the water it draws about 8.4 Amps. Giving me a sparking performance. I am hoping it will give similar 'oomph' on a 7.4v LiPo, but I don't have one to test yet.
Usually available from Component Shop, but they are currently showing them as out of stock/sold out. Not sure if that means end of line. Worth a phone call..


I have about two pages of stat using differing prop, voltage and motor combos, which I shall detail on my Brave Swordsman page over the next few days. Very interesting, but the above set up proved optimal. Revs are over rated in my opinion, it's all about the torque :-))

Anyone have any ideas for the 1/24th version on a single shaft?
