Upgraded prop-Revolt tougher to control

[Jc03]

I am a novice to the hobby and just upgraded connectors and swapped out the stock Revolt 30 prop for a m445. Wow! It's definitely quicker. That being said I'm having trouble with the handling. It seems like most of the boat is out of the water at speed and it pulls a bit to the right. When I rarely try to make left turns it takes a lot of space. What adjustments should I make? Thanks in advance.

try to move your batteries towards the bow more if possible, if not try to drop the stinger down just a touch. The first one will move ur cog forward putting more hull in the water, The latter is just going to try and push the front down a bit. Most people tear out stock batt tray to use Velcro or custom holder as its better for longevity and adjusting cog. Also a video speaks volumes usually in these matters if possible at all...good luck. Double check the trim and travel on your rudder both ways and make sure trim tabs are identical settings on both sides, Usually a pulling in a mono is a not centered rudder or a fairly large imbalance issue...maybe take a pic of your transom and guts to help us out here.

Also if your prop is not razor sharp. It still will turn right but not as bad. I moved the rudder linkage out to the outside hole on the rudder slowing down the action as it was too fast for me too!

Thanks guys. I'll take some pictures. Does anyone mess with the turn fins or just the right side trim tab? The rudder seems true.

Trim tabs, turnfin angle, rudder caster angle, strut height and angle all part of dialing a boat in properly.
Make only one change at a time give it a quick lap to see the difference it made. No point in running an entire battery for a tuning session, I normally do about a lap and bring it in.
I generally leave the CG set at about 27% for most mono hulls and dial it in with hardware adjustments. I also keep notes because a change in prop can throw off a "perfect" setup, sucks to have to go through the trial and error to get it back.
Make sure the prop is so sharp you have to wrap a rag around it when removing it, most props can also stand to have the blades thinned a fair bit, the last few M445s I've handled needed a lot of material removed, very thick blades. Great props but need a lot of work to get them to my standards.
Be careful though the berrilium (spelling?) is very nasty stuff to inhale, I wear a respirator and do all my prop work wet over a tub of water, also only use hand tools, don't want that stuff spread all over my basement for others in the house to inhale if I were to use a stationary belt sander or grinder.
