Are these good for fins on a model rocket?

Depends on the rocket. These are rather thick slabs (I use then for the base of DC powered air propelled cars in engineering education) and unless you have a large model rocket, these would not likely work all that well. Too much weight and fairly thick for typical model rockets.

If you look at the pedestal (the bottom part of the rack), it has a slot in it. That is where the fin inserts and where the weight of the board is supported. This product might work without a fin, but it would depend on what kind of tail the board had. Probably a pin tail or a diamond tail would work best. Then, the apex of the tail might sit down in the slot. However, the product probably wouldn't work so well for swallowtails or thrusters.

They float and the built in tethers work well. I used them for river boarding and the whitewater knocked them off. Fortunately, the tethers held true and I kept my fins for the restof the ride. A great value

Yes...that's what we used them on. Have had no problems with them. Would recommend using stainless steel bolts to attach them to the landing gear.

Not 100% but I looked at other tusa fins and I think that they will. I'd you can remove the strap and it's buckel/keeper or whatever, and there's a round knob that's left for you to insert into this strap system then it'll work. If there is no little round knob then it won't. I hope that helps, it's kinda hard to explain without being able to show it

The fins will work with the EZ-Launch bottle rocket launchers. However, to make them compatible, we have had to glue a white plastic ring over the threads that are located on the bottom of the fins attachment. Be sure and buy your fins from the EZ-Launch screen views. This way you will purchase a set of fins with the white ring and are compatible with the EZ-Launch bottle rocket launchers.Dallas MurdochPresident of EZ-Launch LLC

I think they'd be great for an inflatable boat. I use mine on my kayak when I'm fishing.

I would think so as long as the fins are left right and the vent is greater than 2 inches wide.

I would imagine they could be but they are 3-4 inches shorter than regular fins.

Yes you do! It comes in two main halves and the tail fins also have to be glued together before fitting - nothing difficult if you use tape to hold it together while the glue dries. There are also quite simple cabin and engine assemblies to make, but I did not use these as I customized my model to make a 1916 Naval Zeppelin

not sure. depends upon your fitting. but that is incredibly expensive! they should be dirt cheap.

They worked well for me. They should work for you also, as long as your wheels are close to the 76mm size. Bob

The fins on our was different (smaller than pictured). Regarding the decals, we put them on the body of the rocket instead.

This is just the 2 rear fins for a quad set up. As far as I know they only come in one size. I didn't have a size option when I ordered them. I think they're great, I love the thruster fin set of the Nexus H3's and I own them in Medium and Large. I was so happy when I found that they had the rear quad fins to add to the collection. Sorry, probably more info then you asked for.

Yes...These are mounted and glued with foam inside from the factory. I highly recommend them for any 12mm hex, off-road application. Little tall though, you may need to gear down a couple of teeth on your pinion (motor gear) if you start to run hot. Hope this helps!

No. The fins are very lightweight but are meant to be used over wader booties when float tubing. They cannot be used with bare feet. The geometry is also all wrong for snorkeling. It sounds like you are looking for "shortie" fins like the kind used by body surfers in Hawaii. If you are not a strong swimmer you need full size fins suitable for quick entry and exit in surf or for avoiding currents/rips. Don't try to cut corners on fins. Suggest if you want to cut weight you go to a dive shop and try out multiple pairs of fins. Pick the lightest fins that still have decent fit and a reasonable amt of thrust/surface area for your intended use and swimming ability.

Well we got one stuck up in a tree, so I would guess it's because they are foam and will wear out. When I opened mine, one of the rockets had to immediately go into the garbage because one of the fins was broken off
