Good job racing...where's the Revo Race stuff :P
The Revo rac results still haven't been posted yet so I pretty much gave up on it

I'm running the 4.5 with the 120 spur gear and a 10.8 final drive ratio. You will have modify the motor mount to get that ratio. The car was awesome and the speedo brushless combo was great. never cut a motor all night.

Is the 120T spur a direct fit without modification and which brand?

Thanks.


Since indoor carpet season is coming soon as well as the Vegas IIC race. ..Schumacher Pitspace will have a nice write-up regarding the Mi2EC Foam Spec soon!

The 120 is a RP spur gear. The only modifying I had to do was a slight snip on the little center pulley flange to make a little room for the button head screws. Nothing major and it only take about 30sec to do it right once the pulley is in your hands.

You not having any problem with the 120 bottoming out? When I put one on my car I could feel the teeth protruding just a little from the bottom of the chassis.

I haven't had a problem with it bottoming out at all. The only problem I could ever see would be if I went over a dot at just the right angle but even then iI don't think that enough sticks out to do any serious damage.

I ran a 120 in my car from time to time and had no problems. I usually ended up with a 118 to get the gearing that I wanted though. Nexus, I think you will like the car


Oh and one of the assembled front diffs has ceramic balls and polished rings. The other I never opened. You will definitely want them for the rug. the rear already has the ceramics installed.

jd, I think it's worth considering 2wd electric buggy (probably "stock"). 2wd buggy in low grip conditions is good for your driving skill - it teaches you to be smooth and consistent - both of which are good attributes to being to your touring car racing. There are usually plenty of second hand Losi (XXX) or Associated (B4) buggies around.

There is offroad electric racing at Hobbystation (currently outdoor, soon indoor) and Ipswich. Both are competitive.

Hey guys

After studying some pictures of Teemus car from the worlds I have come up with a few questions. If you notice the rear diff pulley it differs from the standard EC diff pulley. Does anyone know what diff pulley Teemu has installed?

Also the rear hub and front hub carrier doesn’t look like stock EC parts. I believe they are HPI/Hot Bodies parts. Does anyone know if you can fit these parts directly to the EC or if some modification is needed?

BTW does anyone have Teemus set’ up from the Worlds?

thanks in advance

The rear diff pully is the RW one for the origional mission. It is very slightly ligher, and i mean very slightly.

Yeah those do look liike HPI/HB hubs. The rears are again very similar to std ones. We ran HPI ones to test the geometry way back, before production of the EC std ones. Not 100% sure about fronts.

if memory serves me correctly, teemu was running the hpi stuff when he won the euros last year. in light of this, the ec car has rear hubs that are copies of the hpi's, but with a shorter platform for the ballstud to allow more adjustment. schumacher did not change the front end much from the last car, but the hpi and xray knuckles fit on it. you can use the castor blocks from either as well, but neither of them have a .125" bore for the hingepin, so some reaming is in order. the xray's are close, at 3mm, but the hpi's are a bit smaller.

both knuckles (hpi and xray) make for a minimized ackermann effect as the ball studs are located closer to the tire. with the front arms in the mid/short position, or shorter, the standard knuckles actually toe in durring the steering curve, so i'm not sure why we'd want to increase this more with the xray hubs, but they are apparently working well, though not nearly as durable as the standard kit parts.

on carpet (foam tire), where the steering throw is usually limited to a 5 or 6 ft circle, i see no reason why the kit stuff should be replaced.

in addition to being lighter, the rw pullies have a relaxed mesh which allows looser tension of the belts, without changing the tensioner position.

As our top team driver Teemu is constantly testing. If you look closely at other cars that were at the worlds you will see a lot of top drivers running parts from other cars. At this level they are looking for any tiny advantage they can get.

If you measure a Schumacher Hex/Axle/Front Hub assembly for offset (distance from the center of the king pin to the face of the hex) you will find thay are identical to the same assembly on the TC3, 415, Pro4, Cyclone, XXXS, JRXS,etc....they are all identical. The only diffrences are the pivot ball locations on the steering arms. This very slightly changes the cars ackermann curve. Teemu put them on just before the mains and noted that had no effect on the handling of the car but I am sure he will test this at other places in the future...thats his job.

The HPI rear hubs Teemu has were accidentally drilled crooked (while opening up the hinge pin hole fron 3mm to 1/8") in a way that added ~.5 deg rear toe. He tried them and liked them. He destroyed a pile of HPI rear hubs just to make a spare set.

The front and rear pullies are not RW's. They are stock EC CNC pullies that were turned narrower in a lathe. The stock pulley spacers were then CA'd in place as there was no place to snap the stock pulley fences on. Unfortunatly the RW pulleys are a tiny bit undersize and although they are lighter they make the belts too loose.

These are all tiny, tiny changes. I do not recommend trying any of this especially as Stock EC are winning races all over the place without these changes.
