Hi Robert,
Are these comparable to the Robart 520W1 set I have on back-order at Tower? My application is for the Nitro Models Bobcat - should end up around 8 pounds, I guess.

They are a few bucks more expensive than the Robarts, but I would certainly be willing to cancel the Tower order and get them from you if you think they will perform equally as well. Another consideration would be parts - would I be able to use the Robart accessories if I needed to....(I'm sorry to ask such a silly question, but these will be my first set of air retracts, and I don't know all the ins and outs of them.) Also - the front gear is rail-mount, correct?

I would also be happy to review them for you if you think they will work for me, and I'd love to give you my business. You've been so helpful on the forums...

Thanks,
Mark
