Handling problems on a Supervee 27 Electric

[Hopper]

At a high rate of speed, the back of the boat is rocking back and forth making the boat uncontrollable. The boat wants to flip over. Any suggestions?

[NorthernBoater]

How fast are high speeds? As I understand that hull becomes unstable as it approaches 40.

[Hopper]

I really don't know. The throttle is pulled back at least half way.

[NorthernBoater]

Can you give us more info. Are you running the stock motor and prop? If you are not running stock what prop and motor are you running? What kind of batteries? LiPos or NiMh? And what were the water conditions.

Some rock and roll is pretty common with monos, hard to tell from your description. I was running 2s1p, Ammo and some other mods with very good speed. Make sure your strut is level or just below the ride pad. Your trim tabs should be flat with the bottom of the hull. Otherwise you tend to scrub speed. Make ride attitude adjustments by moving your batteries forward, usually at least one inch. The big inprovement I made was to make a new set of turn fins. Really helps in the turns and also help her track a bit better. Fuller has nice carbon or alu. but you can easily make your own to your specs. I run a teardrop style. Give a bit more info and someone else will respond as well. Good luck!

Read this too, excellent help.

My Supervee 27 is all stock... I'm runnig on 3600 NIMH batteries. I'm running on a small calm lake. The boat run fine when the trigger is pull back half way. But as soon as I try to increased the speed, the boat just wants to rock back and fourth. Mading the boat hard to handle and very easy to roll over... Lucky I had tape the hatch down... I roll this boat twice this weekend.... Not fun .....

[Wake Maker]

Does it roll the going straight or in a turn? Have any pics of your boat?

[NorthernBoater]

If the angle of the strut can be changed that may fix it? I am not sure since I have not seen the hardware on the SV27.

try adjusting(bend) the left trim tab down about 1/32"- 1/16"

I just had that happen today, I was moving my batteries toward the stern in increment to get less hull in the water, and I reached a point where there was excessive wobble, there was not enough hull in the water. so I moved em forward to the last run, got little more drag but very stable. But I scuff the bottom 6 inches of the hull any way so.... worked for me

Thats what I do. It slows the boat a tad, But makes it much now stable.

Are the struts adjustable?

The strut is adjustable at the transom if you remove some material at the front of the strut...about 1/8th of an inch. This will allow some vertical movement at the prop

I think I would start there. Raise the strut up a bit to reduce the chine walk, (too much of the hull is being lifted out of the water) then introduce the tabs if it isn't enough. The less tab you need, the less you'll give up in speed.

Up or Down isn't really an option with that strut. Just the strut angle. And its only marginally adjustable with the mod Flying Scotsman suggested.
