So close I can taste it!!!
 

I finaly got a motor!!!!:yipi: Thanks to pb4ugo I am the proud owner of a 1950\7 for my E-Revo. But I am not to the end yet. Gearing is all I have left. I need a spur gear and a pinion. I have the Emaxx tranny with a stock 32 pitch 72 tooth spur gear with a stock pinion (18 teeth.) Kind of small for the 5mm shaft.:rofl:

I spoke with RC Mike last week. He turned me onto the Strobe Slipper. After explaining how I would melt the stock peg slipper I went to buy one. To my Disappointment Mike is out of stock. I tried asking him when they would be back in stock. He is busy so my emails have gone unanswered. Does anyone know when they will be in stock or where I can get one besides Mike? Or is there one that would be just as good? I need a spur gear with about 50 teeth for the gearing I will run. I was going with the 51 tooth Ofna Mike has. (fits the spur) If I was up running I could wait with more patience but I am so close. Any thoughts???:neutral:

Well, you might consider robinson spurs and slipper. The spurs are 32 pitch delrin and the slipper is the disc type and with the correct gear mesh will hold up just fine. Plus you should be able to get them any where.

Have you seen a Robinson with less than 65 teeth? Thats the smallest I can find. I need around 50 teeth for the gearing I am shooting for. I am shooting for 35 to 40 mph.

I think a 66t spur will do, plus mike has pinions all the way to 24 teeth won't that be tall enough?

Its not the height I am trying to achieve. Its the gearing ratio for 35 to 40 mph for my truck.

You're comparing apples to oranges. The Robinson gears are 32p. The Ofna/Strobe setup uses Mod1 pitch. The 65T Robinson will work. The Strobe setup is much stronger though, and if possible, I'd keep looking for a Strobe slipper.

good luck...i've been trying to find replacement friction pads for my strobe. seems everyone is wiped out with no new stock in sight.

the strobe is much tougher than the robinson (which i had before).

What ratio, sput/pinion, are you trying to achive. If you want to run a larger spur than 51 teeth you would need to run a larger pinion to get the same ratio. For example a 51/18 would have the same ratio as a 65/23, both about 2.83/1.

You're welcome:mdr:

For the time being, just drill out some 32p pinions. It's not ideal, but will get you running 'til you have luck finding a Strobe. Don't you have a machinist at work willing? If not I have a drill press at my house we could hack into some cheapo pinions with:yes:

Sweet! Once again Pb4ugo to the rescue. I do have a machine shop here so I will have some work done. If not I will call you in a week. Its good news to hear I can use a 65\24 for the same ratio. Thats the way I will go until I can get a strobe purchased. :yes:

I use RC10GT spurs made by RRP on my emaxx tranny, they have them from 54 to 67 tooth count.

I saw those yesterday. Do I need to make any modifications to them? or do they slide right on? Are they 32 pitch or mod1? This would help.

when coolrunnings asked "is that tall enough" he wasn't referring to the physical dimensions of the spur, rather, meant, "is that high enough gearing" or "is that a good enough ratio" gearing for speed is referred to as gearing up or higher gearing, or taller gearing

I run them with RRP slipper pads, they are 32 pitch.

Do I need to make any modifications to the slipper clutch? I mean do they slide right onto the shaft on the transmission? Or do i need to change some things. Maybe the bearings or slipper plates? Thanks.

No mods at all, use the center hex 'bearing' out of your old spur for the center of the rc10gt spur, tighten down the pads on the spur, and yahtzee.

GRRREAT!!!!!:yipi: I will be purchasing the Robinson Racing Double Disc Slipper Kit for the Associated Monster GT tonight. Many thanks!!!!:party:

But you'll still have the same pinion pickle...:neutral:

Mike has some 5mm 32 pitch instock so I will pick a few up of those tonight also.

I just got an email from mike and he said that the 18-24 tooth gears are hardened so if you get the robinson slipper and spur you could get the 65t steel and that would be very strong.

I ordered some parts.:yipi: It will be a mix and match time though. I got the Robinson double slipper in the Emaxx 65 tooth and the Associated Monster GT in 54 tooth. I am hopping for the GT one to work. I ordered 32 pitch 18 tooth pinion. I also got from Mike a 20 tooth Mod 1 pinion and a 52 tooth Ofna spur gear. I am hoping I can swap the 54 tooth for the 52 tooth and use Mod 1 gearing. Mike didn't have any 32 pitch pinions over 18 teeth in stock. But if the Ofna spur gear works I am on the right path Mike set me up with. Cross your fingers.:great:

Stay away from steel spur gears. It is best to keep the spur gear plastic as it is an easy and inexpensive weak point to replace. Going with a steel spur gear moves the weakest point to the transmission, which is much more time consuming to repair and most of the time more expensive.
