I bought a used aquacraft UL-1 with the turn fin ripped off. I've repaired the are but I have no idea what angle to mount the
new one back on. Its an aftermarket fin that came with the boat. Can anyone post a picture of the boat showing the turn fin angle?
Thanks

If you have a hacksaw or sawzall you can make your own, turn fin conector,1"x3"x.125" x1 1/2 high. You will pay $25.00 +S&H for one made.I can get 8 out of a 4" piece of 6"x 6 x .125 for $19.00 including S&H

Try PMing Grimracer or Jerry Dunlap for how the fin should be mounted.... they will know.

The turn fin backet mounts with the large flat area the fin bolts to straight up and down. So maybe a better way to say it is stright.. You do not angle the fin.

Having said this the fin (at least the factory UL-1 fin) as a 15 deg top break and a 18deg bottom. The bends act as if the fin was mounted angled but the boat has way less chance of tripping in a left correction.

When you get the fin on.. make sure the bottom bend is parrell to the ride of the boat. I check this with the fin hanging over the edge of my work table and the boat sitting on its sponsons and the strut.. O yea.. set the strut depth at 1 and 1/8" deep.

Ok thanks guys. This is a pic going to mount the fin on like this Straight up and down. Look right? I was confused because

Vegas is different. Grimracer is that 1 1/8" to the center line of the strut? Going to try a 42/55 2 blade? Sorry just realized I posted this in nitro section, moderators can move this to electric.

Ronn,

Bottom (tunnel roof) to the table with the strut sitting on the table.. And yep.. the fin is right!.. Good Job

Thanks alot guys. Took this boat out today and ran it on the stock prop set at 1 1/8" deep slight negative angle and polyrc 25c 5000 lipos. This boat rocks. Its fast and extremely stable. Was rough out and the sponsons were barely on the water. I wouldn't dare drive my Vegas this way. Couldn't gps it cause my vegas blew
over and I lost the hatch and gps.

zip tie your gps to 1/2 piece of pool noodle.
