Greetings:
As I rebuild my 4, I have been looking at the tail wheel attachment, i.e., wood block where the swivel mechanism fits, and wonder what would be the best tail wheel. Collin gave me a neat wheel off a wheel chair, rubber/small tube... Collin broke off his similar tail wheel when his wing hit the higher grass near his workplace. And, I understand a few FR-5's have broken the tail section due to side loading. So I wonder if a smaller solid rubber wheel (the one on the aircraft when I first purchased it was off a shopping cart) would slip more on pavement thus allowing the tail to swing before ripping the tail block apart. The solid hard rubber tail wheel gave a really hard taxi ride so I changed it. Now I am rethinking it esp. with respect to keeping the tail section from being damaged.
Any ideas or solutions?? What was original??

I purchased a solid wheel from Great Plains. It fits tightly in the stock fork. You need to drill out the axle holes in the fork.

I haven't used it yet, but it looks to be a strong rim with enough rubber (until it gets worn down) to provide some cushion.

Hello,

I was using the larger tail wheel because the airstrip at work is rough. If only flying from grass or paved the smaller wheels are fine.

I use a 120mm skate board wheel. Have for three years slightly lighter, on grass and hard and it barely looks used. I used the same wheels on my outriggers. It will set the nose slightly higher but not enough to notice any difference in takeoff or landing. Best of all they match my red airplane.

Hello Joe,
so nice to hear from you. Rumours claimed you went to Japan which at least for the last month has had me seriously troubled regarding your well-being.

Mr Brock, I get your reasoning which is sound and I think I read somewhere about attempts of making a tailwheel that would swivel if overloaded, as an overstress-release type of design. The problem with that is that I suspect you would get far more instances when the tail wheel swivelled when it shouldn't than when it should.

I like the skateboard wheels too and had my latest set of RF 4 outrigger wheels for free when I told the guy what I was going to use them for! But Mr Pro, if you are into a contemporary design scheme as James Bavendam remarked you can get wheels with motion-generated multi-colour diod lights for spectacular night landings.......

May the 4's be with you/ Jörgen

Gentlemen,

Can I direct you to this post by Matt:

He can get the proper original tailwheels, just answer his post.

Yours, Bob
