How To Stop Sponson Walking

[TLeyde]

Give it up. That's what UL1's do when they hit that speed. No prop on earth will fix it.

I'm a nitro guy getting into some FE. Looks like I'll just get the PT Stealth all rigged to go then. I was unaware of this never had these issues with my PT SP 21 nitro.

you might be able to get it to settle some with a high lift prop. Octura 14 or 16 series. Post a picture of your air dam as that could be the cause. It may work great at 45 but the additional forces at 50 may be causing the airdam to lose effectiveness

Try adjusting your strut height one way or the other by about 1/8 of an inch. Your transom height should be around an inch
when sitting flat on a table.

The battery mod works great, I even ditched the airdam, was stable at 58, too bad I sold it, I miss that boat

I have done the Battery mod, air dam, sharpened rudder and installed a Prather B220 prop with the strut set at 1" on mine and it is pretty stable

The UL-1 was made with a lot of AoA to keep it loose and fast with the stock rtr setup. Power or prop it up and it does the dance.
Decrease the AoA and she'll settle down
