this is my BBY micro cat it turned out nice but I can't set it up right. everything I do to it makes it hop around really bad. batteries up front, batteries far back, Lypos, stut up, stut down, shart agle, nothing works it bounce like a basket ball, but it sure looks nicev when it is still

props will do it,
balance them and sharpen them
plastic props wont cut it

also depends on how high the prop is and how far it is away from the stern of the boat
WHERE DID U GET THAT PAINTED!!!![X(] THAT WOULD LOOK NICE ON MY VIILAIN EX

that wouldn't cause it to hop
raising the hight would change how lose the boat runs or how wet it runs. the length back from the transom mainly changes the way it turns.

thats the problem with my tunnel and villain ex. i trimmed the motors down and they both stopped hooping

you said two different things.
trimming the drives down and lowering the drives.
both different things.
to trim meant to adjust on a angle and when you adjust them down it will stop that.
but to lower a drive is to make the prop lower in the water with the same angle of attack.

The paint looks real nice.
