what should I try, fix, or buy?
thanks.
Well, I can pass you my experience. A differential that starts perfect and open itself while drivingm up to melt the pulley...
Use thread lock over the diff hub, 12 packs with no slip.

Hope this helps!

Default Lipo tray

for those who have been looking for a lipo tray, I just ordered one over the weekend... Its been a long wait and finally found/got one!! At the time of ordering there was two available, and then I checked today and the second is already gone. It is amazing to see how much these are in demand..

Good luck in your search for one..

I ordered mine at losipartshouse.com

and yet somehow I ran mine all year long with no problems. Like I've said before, they're fragile and most drivers now a days can't drive them, but they are faster

1) 30lb springs front (better)
2) removed rear sway (better)
3) rear shocks brought in 1 space (better steering)

Problem = still alittle lose at the rear (on power out fo courners) and limited steering but changing shock angle (rear) helped lots

sorry if i have not explained this very well still very new to setting up cars properly i am running RP30's (i can use diffrent ones) and racing on a small asplult track in the UK weather is not to warm and running 13.5t brushless spedd passion setup

if anyone can give me some pointers on some things to try next time i race to solve the issues i have as the car still feels very loose on power comming out of the courners and i really could do with a bit more steering. i have set the speed controler to its lowest punch setting

any tips/pointers greatly appericated
If your running 30lb front springs, There is a issue some where.. Thats a carpet foam spring.. Run 17 front to start.

Try this..I have used this as start at all tracks and has worked every where..

Here is set up I been using most recently. Low med bite. Also ran on High Bite and won also. So this set up is easy to drive. May not be fast lap car all the time. But will make car a great car to be in the show in battle for top spot.

Front
40 wt oil 17 springs stock pistons
4 caster blocks
Med wheel base
1 1/2 camber
.5 mm toe out
.40 sway bar
5 mm ride height
2 1/2 mm droop over RH
top shocks #2 hole
Camber link set up #1 on tower and tall ball stud on caster block
spool high
high roll centers
#1 on spindle rod end
#2 on steering rack

Rear
30 weight oil 15 lb springs stock pistons
Med wheel base
No sway bar
High roll center
#2 pivot block
stock hubs o*
rear link 5A w/ tall ball stud
shocks tower #2 outside arm
1 1/2 camber
ride height 5 1/2
droop 3mm over RH
diff low


Motor 13.5 gear 104x45

When I measure droop.. I set car to rh on board. Hold wheel carfully while lifting that corner of chassie to see when car is in full droop thats the droop # I use. Maybe Jason can explain better as I got this from him. But thats best was as car already has droop in sag sitting at ride heifgt. So if chassie is 5 MM RH I need chassie to be at 8mm while in full drop while measuring to get 3 mm.

Hope this helps some...

Hi, this is my first post here and want to say that it is a great forum.

I`m from spain and i run with a typeR, we run in a large outdoor gas tracks medium grip and run with mod and Lipo without weight limit, we run with foams and the rear we use is 30mm(control tyre take off 35), the cars are very fast(only tenths with the gas guys), the car is great and have no traction problems( the motor is mamba max6900) the only thing i miss is a little more steering on power, the tracks are very fast but with some hairpins i run with the stock setup except for softer springs in the front and 6ºcaster blocks(front diff also), have anyone a setup for this conditions?

And also last race was a special format, 30 mins, most people went for two stops but with the "fast" change of batteris of the car i have to go for one (maxamps 6000 and reedy neo1star), have anyone a idea on how to make a fast change of batteris for this car.

best regards from spain

You're roll center adjustments come from your toe and pivot blocks. The aluminum parts that hold your hinge pins on your chassis. If you want a high roll center than flip the toe block 180* and switch the smaller braces from left to right. Just remember when you rotate them that you still have to be in the inside hole. Basically in doing this you are raising your arms further off the chassis.
Good Luck,
Casey

i'm getting ready to run brushless in my type R and i was wondering spur gear are most of you running with a 13.5, i see a lot of different combos but what would be the best one.
also have any of you tryed running a 17.5 in the car?

Get the prs adapter so you have more options, but a 118 spur should get you in the right range, most get a 108 if running the prs adapter.

The other thing you can do is go down to 41 tooth pulleys if you have to put too large a pinion on.

I've built this spreadsheet to easily find ratios for spur/pinion and internal drives for both 41 and 42 pulleys.

It's not pretty, but it works. If you guys can give me an average diameter for jaco vs rp's vs sorex i can update this w/ the rollout calculations as well.

I submitted teh type r w/ the 41 tooth pulleys to this site which is pretty good too: http://www.gearchart.com/index.cfm?f...n=chart.create
