Emaxx slipper Modification (strobe like)
 

There have been a couple of you asking me for pictures of my Robinson Racing Double Disc Slipper Kit for the Associated Monster GT that I modified to fit onto an original Emaxx transmission with the Ofna 51 tooth spur gear. I am not the first to do it here but here is some pictures and info. If you can’t find a Strobe slipper here is a nice substitute. The RR black slipper rotor has 3 legs where the Strobe has 4. The Ofna 51 tooth spur gear has 4 holes to attach bolts. This is perfect for the Strobe but you need to drill out 2 more holes. I placed the slipper rotor into the spur gear aligning 1 leg with an existing hole. Then I marked the position of the other 2 legs and drilled out 2 more holes for the bolts. You need to buy 3 new bolts because the ones supplied in the RR kit are too short to go through the Ofna spur gear. I also made the 3 holes in the legs of the slipper rotor bigger. The RR slipper disks slide right onto the Emaxx transmission input shaft. Works great. Be careful of how much slip you leave in the slipper. I had the nut backed off 1\4 of a turn and I melted the spur gear. The bolts got way to hot. I tightened the slipper up fully tight and have had no problems yet.

I also didn’t like the wobble from the spur gear so I modified that too. I was thinking about buying a Strobe Sprong on eBay but then I read some one else used a bonnet to make one. If you don't know what a bonnet is go to any hardware store (Lowes, Ace Hardware, Home Depot) and go to the pluming section and ask for a bonnet. They are made for faucets. I bought the biggest I could find. Cost me $0.68. When you install it you remove the spring that comes with the kit. Place the slipper stuff on the transmission input shaft. Then place 3 washers onto the shaft. Place the bonnet over the washers. This keeps the bonnet centered on the input shaft at all times. I then used an old Emaxx slipper plate flipped over to keep the bonnet in place. A lager washer would be fine. Then use the same nylon nut to tighten it all up. There is still a little wobble but not much if any. When using a single nut to keep it tight I don't think you can ever keep the entire wobble out.

very good idea, im sure alot of people may try it.....good job.....

Hm, very interesting. Certainly is a cheap thing to try out. I hadn't thought of running mod 1 gears on the RRP slipper, well, not after I saw that mike was making 5mm bore 32P pinions. I only wish they were made in a hardened version so I could run the steel spur.

I can attest to the heat the RRP slipper makes. I just about burned myself on mine. The adjustments needed to make it work are very small, but it does work well.

That's a nice idea! I might just try it!
