If you can pull a X637, you might be able to pull a X437/3. You might have to take some blade out of the X437/3. The X440/3 is real popular with the 3.5 vee hulls.

You are running a 637? That has more pitch than a 437 I believe. I think you may even be over propped and not getting to a good RPM range.

You might try some smaller props like a y535. That's a good prop and could get your rpms up where you have more power. Just a guess,.. worth a try.

THANKS I WILL TRY IT RANDY FROM BBY BOATS HAS THE SAME BOAT AND CLOCK IT AT 42MPH WITH A X637 TEXAS CUT MY SETUP IS CLOSE TO HIS BUT IAM ONLY RUNNING 33MPH I GUESS HE REALLY WORK ON HIS PROP??? :blink:

 

[anthony_marquart]

Same motor? I have a WT12 with and OS TR 12 in it. I bet its running close to 40 with the y536. I plan to try the x637 on my .12 rigger, Bantam12.

I've turned an X-440 but it was rough. My engine is slightly modded with one of Izitibrokeyet?'s Nova Rossi .21 carbs which made a huge difference in speed. I've found the X-637 to work pretty well on mine but it depends on your setup also. Try tweaking the pipe a little also to find out where it's making good power if you haven't. I'm running my Mac pipe at around 8-1/2" and could maybe mess with it more.

My .12 mono that I built years ago with a Trinity/Picco that was radared at 33 MPH and not tweaked so yes, you must be lacking something but I don't know what to squeeze more speed out of that boat. Weight is the biggest enemy of the small boats and you have to go lighweight in everything, mini servos, a small RX and lightwieght hardware all help to dump weight wherever you can. Glenn Quarles was trying to shave grams off his record setting hulls in his quest for more speed.

I too may be shopping for a new hull once the Andy Brown .12 comes out as my Wild Thing 12 (the wood version of the WT 26) is made for side exhaust engines and not easily converted.

YEAH I HEAR YOU RON PRETTY MUCH ALL MY HARDWARE IS MINI SIZE WEIGHT IS NOT THE PROBLEM BUT HEARS SOMETHING IAM HAVING A PROBLEM WITH ITS ENGINE TEMP MY ENGINE RUNS AROUND 125 DEGREES TO COLD??????WILL HAVE TO CUT SOME FINS OFF ENGINE HEAD????WILL IT HELP MY SPEED INCREASE :blink: :blink:

 

[anthony_marquart]

That is it!! Unless it's real hot out you have to take some cooling off the engine. I usually tape off the head until I get the temp up. It made all the difference in my .12 hulls. 125 is VERY cold.

I'm building the latest version of my bantam tonight. It's turned into a really nice hull.

THANKS FOR INFO GUYS

 

[Ron Olson]

On the previously mentioned Trinity/Picco I picked up a spare heat sink head and cut the top 3 fins off and it still ran cool. Seeing how the engines do get a lot more air than one stuck under a Lexan body plus the cooler air off the water, they will overcool.

MAYBE MAKING A COVER FOR ENGINE TO LET LESS AIR GO THROUGH MAY HEAT IT UP MORE :unsure:

Albert,

You may want to try a X-435 and see how this works, and then add some additional

cup to go faster in the future.

Good Luck Testing,

Mark Sholund
