Cheetah struts are pigeon toed - Normal? Fix?

[MikeP323]

The struts on my Cheetah are both at an angle towards the center line of the hull. These are original 110 mm struts on an undamaged hull. The angle appears to be equal as near as I can measure. The transom mount area appears to be square with the hull. The hardware holding the mounts to the hull is ALL TIGHT. When I remove the struts to grease the ball area I am tempted to bend the two arms that hold the strut on and correct the angle. Is this a way of solving the problem? Is this a problem at all?

Has anybody found a replacement strut that is sturdier than these? Thanks for any help on this

Those original TFL 110mm drives had no support to them and never really stood a chance. It was a bad design from the start. I have the same set on my Cheetah, but they've been cut down in length so there's considerably less lateral load to bend them. My friend's twin Fightercat Daytona bent one after a cartwheel style flip this summer. I'm removing both of them this winter with a drive that has a pedestal support mounted to the overhang.

ProMarine swapped them out on their twin cats for the new TFL adjustable stinger. It's significantly stronger in all directions, but will require new mounting holes. Hopefully, the existing stuffing tube locations will work out on your Cheetah and only the mounting holes would need to be changed.

First, I've got the ProMarine Skater X2, and I can tell you the TFL stingers on it are outstanding. Although mine arrived with the stingers slightly out of alignment with each other (starboard side was a bit high), a quick adjustment, and they were prefect. Even after several flips, there's been no damage to anything.

In regards to the struts on your Cheetah, I'm just curious about something - how does cutting them down "reduce lateral load"? I'm not trying to say is doesn't...I'm truly curious, and trying to 'learn'. I mean, of the off-angle were quite large...say, greater than 5?...I could easily see shortening then as don't that. But, if the angle were minimal...say, 3?, or less...then I'm having difficult seeing how any noticable difference would be achieved. I completely understand how 'angle' and 'resistance' (ie. "lateral load") work against each other...the greater the angle, the greater the resistance; the lesser the angle, the lesser the resistance; no angle, (virtually) no resistance...but, if there angle is so minimal, then, as I'm thinking it, the resistance would be so negligible as to almost be non-existent.

fweasel - thanks for the reply. Those shortened drives do look like they would be less likely to be bent in the event of a flip or argument with a turtle. I have been using that TFL stinger for a while now on my monos and it is a good item. I would not have have thought of using them on the cat like that but it looks like a solution to the problem. I was wondering what unit you had found that had the pedestal support on it or are you going to make them from scratch?

The pedestal supported drives I'll be using on the Daytona twin are also from TFL. My buddy is on a budget, so those are relatively inexpensive. There's not enough overhang on the Cheetah, or height for that matter, to use that type of drive without a custom set of adapters attached to the rear of the hull. I don't plan on changing the stingers on my cheetah because it's setup for 4S oval racing and doesn't see the blow over abuse like my SAW cats do.
