Default what I learned after going to the track for the first time in 10 years

just got my old school Yoko MR4TC set up, had to go to the track hobby shop to get a sensor wire for my 21.5 brushless.

1-the gearing I used 10 years ago for a 17 turn double DOES NOT work at all on a 21.5 brushless setup (87/22)

2.above gearing makes the car SLOOOOOOWWWW, like not even funny slow.

3.nobody at the track had even heard of a MR4TC Yokomo, I must be old.

4.people at the track were just as nice as I remember from back in the day, giving me tips and stuff and helping me get rid of my bad habits I have had forever (letting go of the wheel instead of controlled return...lol)

5.my 10 year old had more fun driving the car than I did, the joy on his face was priceless......(and now its time for me to get a new car lol)

6.modern spur gears do not fit a 10 year old Yokomo lol.

7.modern rubber and shock setup/springs make that old Yokomo glued to the track though!

8.Ill be back for more in a couple days after I figure out something with my gearing.

Your 17 double would have been somewhere around about a 10.5 boosted, ish. So no, the same gearing would be nowhere near.

If you're running blinky, the pinion and spur are going to start to look quite similar to each other for 21.5.

Number 5 is the best! One can not put a price on that, well worth the cost of a new car and radio.
Welcome back,

yeah I did the math, my FDR is like 6.38!!!!! (my motor was getting warm, ESC was cool) I dont know how much more pinion I can get on that bad boy though lol. Spurs are non-standard and non-available for that car anymore, oh well. Im just going to set it up as a brushed silver can for my son and Im going to pick up a Spec R or something lol.

Is it the Shaft drive? If so, I have heard good things about it for 21.5 class or USVTA 25.5. Might be hard to find spares, but not sure on that car.

Check out: http://www.rctech.net/forum/electric...etitively.html

I assume you are running 48p. IMO - I would go 64p and get something between a 80-84 spur and some big pinions 40-50 range depending on the class. Ask what FDR range people run at that track and go from there.

The beauty of VTA.... new life for old cars. You should give the class a shot with this old sled and see if you like it.

the handling is there on this car, but I just cant get the FDR anywhere close to competitive with the spur that is on it, it is a weird offset spur that is not even available on ebay! I might look at it some more today and see if I can rig something up to work.

haha, yeah that something I forgot to add, I love 2.4ghz radios, best addition to the hobby in the past 10 years hands down. I picked up a cheap one on ebay when I was rebuilding my car.

Default Spur gear adapter

I have the part you need. However, with the stock spur (78) and a 27 pinion should give you around 6.35 FDR. The internal ratio is 2.2. Hopefully this helps.
