good starting prop is a m445.....can work it up or down from there

Agree, great prop to start with(m445) and check the temps. If everything is ok, you can try to step up to the m447, but watch the heat. I am using a worked over m447 by Mark Shouland(sp?) for my Insane FE in P-spec. Nice job on the boat!

Don't know how you guys turn a 45mm prop on a UL-1 motor. When I try I get 3 regulation laps before it detonates.

Ray,

Same down here with later 2030 motors, particularly in the P-Ltd Cat class. We're mostly all propping down.

ok? so maybe a , 442 or a 440? really don't wanna mess up things, at least my 1st sport 20 hydro.thanks for the warning.

[Doug Smock]

A 442, 4255 etc, is a safe place to start.

[darryl whitman]

thanks Doug, I'll start with the 442,

I have the same boat and I run a M445 with good temps. If you want to prop down go to a x442 or cut down 445. I would also go to JRS Innovations for his motor mount, servo relocation and receiver mount. I have a build post of mine if you search under my name. Let me know if you need anything else.

Here you go

Very nicely built boat Darryl. I like the x445, but like some others have said, I am hearing little bits of the UL-1 motor not being as robust as it use to be. I wonder if the 1800kv version has more wattage ability?

thanks Mike, I do have an 1800kv, so maybe start with an x445 an work , up to a longer prop? Im still a noob .LOL also in Pspec class can I use any motor
that is rated the 2030kv an or 1800kv , an still be legal .?

Depends on your local club but, according to NAMBA for a sanctioned race you would need to stick to their rules. One of our local clubs doesn't care as long as it's no larger than 36mm x56mm and under 2100kv.

thanks Ray, I've been running with the locals here , an they r a lot of help to me , I'll see what rules they follow. but for the most part we all have fun.
