impulse 31 motor timing

[sansouci01]

wanted to check and see if the timing on my new impulse was set to soft or hard. turned on the transmitter, full power than turned on the esc waiting for the beeps. instead the motor went full power. am I doing something wrong here???

Hi, I just got an IM-31 couple days ago. Sold the stock ESC & radio system so I only did a brief function test; I tried to scan the ESC instructions but it's a fold open type deal, after several unsuccessful tries I gave up.

Based on a couple years worth of experience with car / truck ESC’s I’ve learned that program boxes make things FAR easier. With that said here’s the one you need for your boat… http://www.proboatmodels.com/Product...ProdID=PRB3311

Personally, if it were me, I would get a Seaking ESC and sell the stocker, that’s what I’m doing (stocker is already sold). The program box I use for my trucks also works with the Seaking, primary reason for doing the swap. More info about the Seaking’s is here… http://www.hobbywing.com/product.asp?bigclassid=12

If your on a budget, I've got one of these... http://www.hobbywing.com/product_show.asp?id=223 - that I would be willing to sell, I want to get a 90 or 120a unit. Mine was only used a handful of times and only with 8.4v NiMH batts; I've got pix if your interested.

Hello.
I just got the pro boat program card. Makes it much easier. The timing was set to soft so I changed it to hard and going to run it today to see if that makes a difference.
So far all the stock electronics work well in the boat. Everything is cool after a run. I'm sure that the temps might go up a bit with the timing changed.

The proboat motor likes soft/low timing...
Be SURE to change the throttle to LINEAR. Default is Logrithmic, which maxes out the power at 85%. I would also turn off Brake while you are at it.

Hey Chief,
As I mentioned in my 1st reply I'm going with a Seaking speedo, as I'm sure you know HW express's timing in degree's - choices: 0°, 3.75°, 7.5°, 11.25°, 15°, 18.75°, 22.5°, 26.25° - which would be closest to PB's "soft/low" setting??

Thanks - JW

The 11.25 is what you want with that motor,
Hears a link to some info on that motor.

Thanks Lenny (x2), I was just getting ready to ask about running a x442 instead of the m445 others recommend.

Steve & Jan both sell CNC'ed x442's - $20 range, m445's only avail raw or sharpened & balanced ($40), I would need the latter.
