I just got a OS 21 RG from a new friend onthe forum, thanks a bunch F.F.M.
Well I got the 2050 pipe for the RG andthe King Headz clutch shoes.
Now the RTR has only 2 shoes so do I take those out and put all four aluminum ones from king headz or do I leave the two that come in RTR and add 2 aluminums? Also WHAT CLUTCH SPRINGS DO I GET? And which glowplugs are good for the OS 21 RG?

Hello Guys,
I've finally finished reading all 70 pages of this thread. Lots of good info! As I read through it I took some key points and questions that seemed to be asked frequently and build a small Losi 8ight fact. Which can be found here:
http://rcbros.com/forum/forum_posts....879&PN=1&TPN=1


I come from a MT background, took a year off from that and ran1/10 scale truck, I stepped up for this season and just purchased a losi 8ight.

I think for the most part after reading this thread, I have a plan and basis to start from. But I do have a few small questions..

1. I know the throttle servo isn't a problem when setup correctly, I have a Hi-tec 5955T and the Airtronics 93458. Normally, I would run the hi-tec for steering, but do you think because of the possibility of a fried servo, I should run the hi-tec for throttle?

2. With my MT I was really lazy when it came to shocks, and I was wondering if anyone would be willing to create a how-to on how to properly build the losi 8ight shocks. Using the thread lock, and the green slime etc.. I would like to make sure I'm doing it right. Shoot, I may even shoot you a few bucks as well.

3. I got my buggy used, and a lot of the buggys I looked to purchase had "recently replaced" there CVDs. Any reason for this?

Thanks!

for your 3rd question, it seems when you land hard the chassis flexes and the drive shafts try to follow but they dont flex back.

The 5 port motor would have more bottom end and less top. The 7 ports are usually smoother to drive with not as much on the bottom end but more on top end.

Actually the 5-port and 7-port GO motors are both 5-port motors (5 intake ports). The 7 port just has different exhaust ports. They are a clone of the Novarossi P5's but at a much lower price. Personally, I'd get the version labeled as a 7-port.

I have one of the 21BF 3-ports and it's an excellent motor for the price. I've seen a few dyno graphs of the OS VG and it doesn't look too bad either.

But out of those, here's my order of pick:

1] Go 7-port
2] Novarossi 21BF
3] OS VG

Cool Here you go Trebor.....

As far as clutch shoes go, If you got the 7075 versions they are considerably different than the stock Losi shoes. I would run all 4 7075 shoes with 2 light springs and 2 heavier springs. This will give you a nice smooth clutch feel.
I can't remember the springs off hand but I think Blk on two and Gold on two.
Put them on opposite sides.

The RTR shoes are softer. You can play with those later. I would use a heavier spring on a softer shoe when it is combined with a harder shoe. This would give you less wear when the harder shoe engages early in the engines RPM curve. Then when the RPM gets high enough you get max grab with the soft shoes.

For the RG just get OS 8 plugs. That is a great combo you have with the RG + 2050 pipe. I race with it all the time and never feel out motored. It gets about 8 1/2 minutes of run time.

Let us know how it goes.
TEX

Hey Tony....

Have you ever tried the V2 version of the Sportworks 21? It is a darn good motor for any price. It is a true 7 port, makes loads of power, comes with restrictors and is about $175. We have one with over 7 gallons on it and it runs like crazy.

What is a good link for the GO motors? Maybe we need to carry them.

Thanks for the spring rates.


Setup issues.

I have tried many different things to try and get rid of the onpower push that I am dealing with. The tracks I have been racing on could be some of the issues. (indoor hard packed clay and often getting dusty.)
I was thinking if I stiffen the rear shock spring it could help a little. Now I am running the green spring. If I go to the Black spring could it help keep the weight up front more on power?
The droop is something else I will play with this weekend at the KY state race.
