trying to mod a koralia 1

[flyguy7150]

Hey, i'm trying to use a bigger propeller, using whatever the black prop is from the sureflow mj mod kit. I have everything so it fits perfectly, but i can't get the prop to turn underwater. It'll spin nicely in air, but once submerged, it just stops...Any suggestions??

I also started a thread about wanting to mod a K1, They are so weak arent they? I love the K3's.

But no one ever responded to the thread

they are really weak, 400gph rating is a joke. No matter how wide the flow coming out, its not 400gph. I have a K4 as well. Anyone else with ideas why the prop won't spin underwater?? Is it too heavy for the motor to turn?
