ul-1 motor/esc setup for the sv27

[brad65]

Well brad you were right. Took the boat out today. Calm water speed was 45mph. 4mph gain. Ran it for a little loner. The boat stopped out in the lake. Thought the batteries were dead. Waited for a bit and brought it in and I had melted the solder off of the ESC. WOW! first time for me. and one of the sides had fused one of the male ends into the female end of the battery. So I'm going to upgrade to bullet connectors and find a different prop. Any suggestions on what would be a good prop?

I tried the prather 220 and speed was 37mph. I want to stay in the 40mph range but want to be able to run through a full charge on the lipo's.

Anything 42mm to 45mm seems to be a good size to stick with. I'll let ya know how I make out tommorrow with the 42x55mm grimmracer, hopefully its alittle faster than the stock motor and a 45cf. Also how is you water cooling. I added a tube pickup, even though it slows me down it flows twice if not more that the rudder pick. Stock rudder pick up is junk IMO
MPH doesn't matter if you can't run it full bore all day long

[brad65]

she's a moving!. Whats your temps with the rudder cooling?

[Leskimo85]

I don't have a way to check the temp yet?? Today I'm adding a second water pickup and will be running two water cooling. You run yours today??

[brad65]

yup, its faster but nothing OMG to write home about. Well thats with a 42x55. Your running 48MM size which is alot bigger. I'm guessing its running about 37 maybe.

Yea with the Prather 220 I was only getting 37. I'm thinking about trying the 230 maybe.
You have any video??

Nah I should but its not much more than some of the others on youtube with stock stuff. I wish I had a 48cf to try just for kicks but I'd take it off, since I run full out with a buddy and the big props seem to kill esc so that just not fun IMO

[bustitup]

just a heads up
I have new ul-1 motor and esc pm me

Did you try the new setup with the carbon 45??

[brad65]

Did you try the new setup with the carbon 45??

no not yet, my cf45 is chipped pretty bad. I bet it does better than the 42x55mm tho

[Leskimo85]

Yea! Have you looked at the Octura m645? It has a smaller diameter then the x646 but almost the same pitch?

Nice, the cf45 is my favorite cheap prop, but I wish it had more pitch

[Leskimo85]

Yea I know. It's hard to try different props when they're kinda pricey.

Leskimo85, are you getting 37mph using the UL-1 motor on your SV or was that speed with the factory SV motor..
I know its a different boat but I use that prop on my UL-1 and am getting close to 50mph...

[Leskimo85]

Brushless, yea I was only getting 37 with the 220 prop and the UL-1 motor and esc. My Brother in-law was only getting 27 with the 220 and his stock setup. So it must be the hull design I guess.
