2nd Wet w/38x55

[LuckyDuc]

See the post above yours.
I wouldn't venture out past that with less than new batteries in the Transmitter. You shouldn't be running a boat further than that anyway as you can't see obstacles in the water.

Moving on

I took everyone’s advice and had 3 nice runs and no shut down problems. 46.5 is about the best I can get with this 38x55 prop. It is a nice prop, but believe that the UL-1 needs more. I am basing this on ride and acceleration out of the turns.

My temps are low. The highest being the motor at 126 (measured at the terminals entrance; lower elsewhere). ESC high is 102 at the cap and the output end is somewhat lower. Maybe boring out those water fittings did some good.

I am moving on to the L38x63…

L38x63, when are you trying this prop?

Try the Octura m440...using my new Hyperion 25c 2s packs UL1 reached 50mph with that prop. I got too much chine walk when I tried the L38 x 63, but it may have been the water conditions. My fav is the Grimracer L40 x 57/3.

I think the X640 might be the ticket for the UL-1. The X645 was WAY too much, the 642 was great for less then three minutes (motor to warm) but speeds were up there. I think someone should give the X640 a try??? just an idea..

Hopefully today if the wind stays down.

I will post the results.

Awesome!

try a m440 took detox's advice on mine wkd well

[jingalls007]

the m440 didn't have the umpf that the 38x55 and the 642 had for me. I think the 640 would work very nice in this boat. Anyone try it yet?

I might try it today i have a 642 that measures 39mm But i want to try my 637 first but i have to finish S&B
