Hi...

Just having a quick look at the forum after a couple of months away and saw your post.

I had EXACTLY the same problem with the Robarts and 4" cross tread Robart wheels on my GEE BEE.

At first I sanded down the edge of the tyres and used washers to space the wheel into the centre of the fork, but when all said and done, the wheel still slightly fowled the fork. I figured when the tyre deformed under landing, the clearance would not be enough to clear the fork itself and thus the model would tip right over....disaster.

After a lot of head scratching into this problem, I ditched the 4" wheel and fitted the same Robart wheel in a 3 3/4" size. I also sprayed the plastic Robart rims white. I used the Corsair rim on the outside of each wheel and the flat smooth disc on the inside of each wheel. It looks really nice....especially painted white.

The fit is ALOT better. I have not sanded anything, but have still had to use washers in the axle as spacers, as well as a Great Planes wheel spacer collar inside the wheel rim in order to seat the wheel in the correct place on the axle. I forget the size of this spacer but can find out if you need to know.

In my opinion, the 4" wheel is simply too wide to fit between the fork of the Robart Struts without it fowling somewhere. During a rollout after landing, if it caught, to be this would be like slamming on the brakes and would tip the model for sure.

If I were you I would discard the 4" wheels and go with the 3 3/4" instead.

My Gee Bee was finished about four months ago now. She is a thing of beauty, yet I have not flown her. I am not an experienced model flyer although I can fly reasonably well and am a pilot by trade, so I understand exactly how planes fly, but having read this forum, I am reluctant to let my Gee Bee come to any harm.....mad some will say.

I fitted her out with OS 1.20 pumped, on board glow, and I have all the charge points and wiring behind the cowling. I have drilled no holes anywhere in the fuselage to fit switches etc. It is a very neat installation and keeps the aircraft looking nice and clean.

I did not install the pilot, but instead fitted a headrest to the back of the cockpit as I felt the pilot figure made the model look too 'toy' like.

I have pictures and can mail them if you like. Also if you want to know any more then let me know and I'll do my best to answer.

Mine took nine months to build.......but what a baby I had at the end!
