Hello,
I have had a lot of requests for another carbon fiber gear size for Q-500 planes. The mounting foot print will be 2.9 x 1.4" , the spread will be 7" wide and you will be able to locate the axles from 2.9 - 2.6" high. I will have pictures ready in a little while and they should be up on the site within the week.

The first of the new smaller gear are ready. Here is the first one out of the mold.

Don't the Q500 rules say the wheels must be 8 inches apart?

The new manual states 7" apart. Rule change that I hadn't noticed until now.

Hello,
This change slipped by me too, but when I had guys start to ask for the smaller size I read the book and saw 7" spacing in now the new minimum.

Interesting, I don't recall that rule change. Anyone shead some light on when it happened?

Barry,

That was part of the 1999 NMPRA-sponsored rewrite of the entire RC Pylon section of the rulebook. Someone on the committee pointed out that several of the most popular Q500 kits on the market were shipping with gear that didn't meet the 8" spec. Since there's little or no difference in the aerodynamic drag between a 7" gear and an 8" gear, and the ground handling evidently doesn't suffer from the slightly narrower track on this size of airplane, we said why not just specify 7" to avoid needless arguments. The main thing is to avoid tandem or monowheel arrangements.

P.S. The closer the wheels are to the propwash, the more drag ... Bwahahaha!
