I have a small problem with an RMT BEEP. Having only four wheels, and one having a traction tire, the unit has problems on our club layout that has one of the outer rails dedicated to signaling, there is only one wheel that actually pickups from the outside rail.
What I'd like to do is find someone that has BEEP parts around that has a set of wheels without the traction tires and swap those in place of the set with the traction tire. Taking the traction tire off really doesn't solve the problem, then the unit teeters on the other wheels as the groove for the single traction tire throws things off.
I'm making the assumption that since both sets of wheels are powered, that the wheel sets will be the same except for the traction tire, having never had one of these apart to that degree. If that's wrong, I'd love to hear about it, then I'll have to consider plan-B.
