Is it a kit or the arf? I put a sulliven tail wheel on my sse and it works good. I had the kit version so before I coverd it I added a plywood reinforcement peice in the very peak of the tail. Then I just took the tailwheel bracket and lined it up to where the center of the axle pivots right on the centerline of the rudder. When that bracket is screwed on, you can then attach the spring wire to the bracket and on the other end just bend an "L" into it and poke the wire right into the bottom side of the rudder. I dont have any pics with me of my setup but it was not hard to do.

Depending on the tail design, you can remove(cut away) about a two inch long(front to back) and 1/4" deep section of the lower aft fuse. Then replace with an appropriately sized piece of plywood. Now install the tailwheel with small headed wood screws to the plywood. It is very difficult to use the little bolts in an already assembled plane. Even if using the Sullivan TW on a new build, I attach it using wood/sheet metal screws. It makes later removal so much easier.

Ok thanks. I built it as a kit so I can still chop wood sense I have not covered yet.

You must have some big motor or maybe a brick on the front of your sse. I just noticed that little chunk of lead on your tail.

ok here is my attempt at paint (not very pretty)

the ply reinforcement should go right about where it shows in this picture. just right above where you will screw on the tail wheel bracket. All it does is gives the screws a little more something to bite into so they dont loosen as easily.

here is a picture of RCKens SSE with a sullivan tail wheel, turns out their are a lot of threads about the SSE and Sullivan tail wheels.

Here's a couple of pics from my last SSEbuild. You'll notice that the Sullivan TWassembly kicks the back end up pretty high. Initially I didn't notch the white base to clear the stab / fin strut half-clevis's. With that slight modification it looks and handles much better. Also, add a bend in the TWwire - check the difference between pic 1 and pic 4 wire angle.

.
The c.g. on the plans is way too conservative, and really needs to be a lot further back.
I had an MDS .46 on mine.
I had to go to an aftermarket landing gear to get prop clearance... using an 11x6.

Ok thanks Guys. I just got it mounted, thanks for the pics. I put a plywood piece on the bottom, and put T nuts in, and bolted on, and connected a pull pull system, works out great!

An APC 12.25 x 3.75 with a 46 works very nice. Ya gotta pay close attention to prop tip clearance with the Sullivan TW - like Tall Paul said - might look to a taller LG. I'm thinking that I used a SIG Kadet Senior piece on one and a Dubro composite on another.

You'll have a ton of fun with that SSE! Enjoy it.

Would you say its for a begginer sport flier. I got a saito 56 on her. How will it fly? I fiberglassed the fuse, which added only about 3 onces to the weight. Will she fly nice???
