Wow. Went back to the old thread for build tips. It's hard to belive this was over three years ago!

Congrats on the maiden flight. I believe you are the first!

Were you really the first to have/fly one ?

It was the first production model to fly in the world.

A Readers Digest version of the original build thread. Everyone can just copy the list and add to it as necessary. Thia airframe has been out for several years now and has an impressive track record for build quality and execellent OEM supplied hardware. I'm sure there are some that I am forgetting, but here's a start.



1. Discard the OEM wheels and tailwheels and replace.

2. Harden the cowl mounting wood tabs to prevent crushing.

3. Use neoprene backed washers for the cowl mounting bolts.

4. Add glue/reglue canopy front latch/hooks and tabs.

5. Inspect/glue wing anti-rotation pins.

Is there any replacement set of wheels that you would recommend?

I use a set of Sullivan Skylites. 4.75" IIRC. Very light and very durable.

Awesome Robo.... Been wondering what would be a good fit. I really didn't like the wheels that came with the plane.

 

[Super08]

On mine I had to go to a bit smaller wheels as one of mine was rubbing on the wheel pant inside at the top.

I'm actually running the stock main wheel and they are hanging in there without any issues.



Now as for the tail wheel assemble, I replaced mine with a Whiterose set up.

Stock one didnt last a dozen flights.

I fly off pavement and don't need 5 inch wheels, so I went with 4 inch Dubro's and saved a little weight as well.

That's amazing. I think mine lasted a dozen flights or so before the rubber quit holding inside the hub. Same with the tailwheel.



When I installed the CF main gear I mounted the wheel pants a tad higher to avoid the larger wheels hitting the inside top. The tailwheel assembly is fine but the wheel itself didn't last much longer than the mains.
