M445 and X642 question

[kfxguy]

NICE! look forward to watching another one of your builds, I've learned a lot watching you build and tweak that Rivercat.

Gonna be a bit before I get started tho...I have two more rivercat builds to do. I'm hoping to get mine in the 100's this weekend altho I'm quite nervous about it.

Good luck I can't wait to see the video of a Rivercat going over 100!

Weather is horrible today so no boating for me. I meant to ask this yesterday. I'm swinging an M645 which I know is a big prop for this little 30" hull. The problem I'm having is it wants to turn hard right when I get on it. I have to have my radio trim set left like 15 clicks just to make it go reasonably straight then when I let off the throttle it turns hard left. I tried lowering the right outside trim tab a little bit, but didn't seem to have any effect. Anyone have any suggestions? Thanks!

pretty normal for boat to go to the right, it is the prop walk that pushes the ass around to make it pull , try a different prop,,,,the thinner the better to preven prop walk,, next move would be to build some Left turn into the boat what I mean is use a airplane motor wedge or that a 1/8- 3/16 piece of plywood and put it on a disk sander and make a wedge to place under the strut mount you also will need to bend the stuffing box for the best alignment you know that will scrub 3-5 MPH Chris

Hey thanks Chris! So what you're saying is wedge the strut so that it is makes the boat have a little left push and when you say angle the stuffing box are you referring to the stuffing tube? I might have to give this a try!

[dasboata]

Yup correct !!! next thing would be to try my props :Peace_sign!

I tried one of dasboatas props...bigger than the one i normally run...and the one i normally run prop walks.....his did not. It drove as omooth as could be. give him a shot with an m645....i think you will like it. or he could do somthing higher pitch and diameter and turn the diameter down for you....best of both worlds...more pitch...more speed...less diameter...less prop walk.

Thanks Travis my SAW cats driveline you will get the idea but change prop 1st

I've used a Dasboata prop on this boat before. They are nice I'm just a do it yourselfer. Here is one I just worked up for my dad this morning. image.jpg

It's a nice finish,,and blending, ! I would not trust the balancer the shaft should have air on 1 side not touching,, (can't see the other side but I got a feeling ) and IMHO the magnets are too strong and holds the shaft to tight

I need a balancer like that. I have a top flight at three moment

[Kaotic]

Actaully I use my top flite for fine tuning this OSE one is great for when you're on your bench top sander and you want to throw it on real quick to check for balance. I like it because you don't have to mess with those little black shaft cones. Then when I've worked up to 800 grit on the sander I sit down and do some hand sanding and use my top flite balancer. It's what works for me. image.jpgimage.jpg

top flight is fine execpt for the cones use a 3/16 pointed shaft instead
