34/34 =200 mph with added weight and good aerodynamics

I got my great looking spur adaptor last week. Thanks Mike! I installed it on my new DM-1 instead of the gtp. It just took another flat spot on the spool shaft to line up with the pinion.

I also used it as a 36t pinion with a rcm 8mm-5mm sleeve on my XO-1's 1717.

I might get another one because they are so versatile for me.

Man, I never thought about using it as a pinion adapter!

Using it as a pinion adaptor, you sure can get some nice size pinions on there!!

Just ordered a spool today for my recently acquired late model.
