I use the RD Racing Starter box to start my 1/8th, 1/10th losi, Truggy, and of Course Revo.

If your having problem with starter being stiff try pre-warming the motor to get it started for the first time until its good and broken in. This will make your life waaaaaaayyyyy easier when it comes to fresh motors and Pull starts.
IMO

46u I added a bunch of shots to my gallery too

But changing all the pegs and motor around is a pain particularly if you run more then one class on the same day. I think I will just get one for each vehicle or at least have 2. Will check out your gallery, I just wish they let us post more the 10 pictures in it.

right before my truck runs out of fuel and dies the engine revs way up..i was wondering if this was normal or if i should do something about it, i think its because right befor it runs out of fuel alot of air mixes with the fuel in the fuel lines, but i could be wrong...any suggestions???

Yes this is normal as it leans out when running out of fuel.

i have a mt 2 rtr...i have had it for about 5 months and i have a os 18 tz motor in it....it is wicked fast but my rear diff keeps stripping....i have the hardened one and i put a new one in today and it stripped in 3 tanks its kinda angering. would aluminum diff cases prevent this because i think the torque fromt he motor pushe the case apart a little giving it a bad gear mesh?

I have the 18 TZ in mine and do not have a problem. Are you shimming them when you put them together?

Are they striping or melting? The reason I ask is the only spur I had a problem with in over 6 gallons of fuel was when I was breaking it in and it melted do to the sorry stock composite clutch shoes slipping so bad it got the CB so hot it melted spur. I have at least 6 gallons on the spur I am running now. Setting mesh is critical as well.

You can all so shim the pinion gear. You want as much tooth engagement as possible with out bind. I have only had my TZ in for a couple of months but have been running my MT for 4 years with MANY gallons throw it I only striped my spider gears once and to date never striped my ring and pinion gears.

When you get done putting the Diff together they should turn free and have a very small amount of gear lash.

could the slipper clutch being to tight cause them to strip this quickly as well?

I have run mine with the slipper tighten all the way up for over 6 gallons and most with the Savage run it that way. If it is not new I am guessing it has run with out problems with the stock shoes. So I am guessing you are not getting the mesh and aliment correct. Sorry to say some have problems with this. How long have you had the truck? Did you buy it used? Do you loctite the motor moung screws?

Will cost a good bit more then $50 I would guess around $100 to $150. Shocks alone would be around $35.00. Then wheels tires A arms, shock tower, drives where the wheels go on. knuckles, drive shafts so it very well could even be more. I think you would be much better off buying the SS kit unless you can pick the parts up REAL cheap.
