I hadn't built a tamiya buggy since the 80's.

While I bought swaybar and camber links sets for this, I wanted to build it all-stock initially.
I had read the upper arms needed clearancing to allow full throw.

Interesting, these are the shock pistons for the "bonus-item" oil filled shocks.

Electronics going in. The tamiya esc is an interesting one, it does both bushed and sensored brushless motors.

It ran better than expected. So I decided to race it Sunday. It did well, scoring 2nd and 3rd in qualifying, and 3rd overall in the A-main. It was a bit slow, with it's 25t "torque-tuned" 540 motor, but it was quick and smooth to accelerate, and the stock tires did surprisingly well, despite having no foams, and not being glued.

Nice one Andy. What are the rules with motors?

Well than, What are you waiting for? :mrgreen:


Cool looking buggy Andy and I like the color on it. Goes well with the colors of parts that come with it.

Are those dog bones in the back plastic? They look awfully thick for a buggy.

You came third running the 25T motor..... while others were running brushless?

Yes, I'm pretty sure I had the only brushed buggy out there. One of those buggy's was in fact..... my old bandit (5700kv).
It should be noted that I crashed very little, so that helps a LOT. In round one I got 2nd ..... I also never had to be marshalled.

I think this buggy does indeed need some more speed, but not a lot, or I might exceed the limits of what it can handle. I'd like to put an HPI 15T firebolt in it.
From what I am told though, my esc is not up to that motor. The other thought is to get a 13.5 sensored motor, but I kinda' like brushed better for whatever reason.

Yes they are, only the cross pins at either end are metal. As for what's holding me back.....
Well I'd like to run it some and get an idea of what to put in it. I only have 2 gearing options with this. It uses 32p gears, and comes with a 17t pinion, and there is the option of going to a 19t pinion, and that's it. Probably the first thing I will do is get a 19t pinion, as motor temps have been fine.

That is awesome! Would love to see the looks on the faces of the other racers!

When I was a teenager I was in the local RC Club, we only had 2 classes - 2wd and 4wd. My poor stock standard Wild One was no match for the RC10's that would be lapping me (a lot)!

I loved pointing out that I was using the stock tires..... with no foams...... and NOT glued. :rofl:
They actually worked a lot better than I thought they would. Main reason for not gluing was so I know I can get the stock tires off, because tamiya wheels melt easily....
I was pleased that even with no glue that stayed put and didn't slip inside the wheels.

My plans are for jconcepts "rips" ribbed tires up front and bow-ties out back. That's what I had on the bandit, which has similar weight distribution, and they worked well.

I still need to order some extra rear wheels and some better tires... but... I did order a 19t robinson pinion gear to see what kind of speeds can be gotten out of the stock 25T motor.
I also just pulled the stock esc..... because I just ordered an HPI firebolt 15T motor. :twisted:
I am told this will fry the stock esc, and also, it seems a waste to not be running a sensored motor with it, so in the bin it goes for now.
I just pulled the XL-5 out of my wraith and after a test fitting, looks likes that will be my new esc.
I was going to try and put the rx on top of the servo, but I think that will be a pain and potentially bad..... so I guess I won't..... stay tuned. :)

The HPI 15T firebolt gave the buggy the extra power it needed to clear the 2nd set of jumps in the 5-pack! :)
So........ I'm all stoked about racing it with it new found power. 8)

Then.....


Broke my rear shock tower practicing the night before race-day.... #-o :(

Cut the top half off a nitro-slash rear tower (from a part-lot I had). :idea:

Fitting the larger (and taller) XL-5 was a pain (had to relocare the rx a bit.... but was worth it once the more powerful 15T motor was in place.

Nice work on making a new tower for the rear. Looks stronger that the original unit.

Thanks Jeff, I think it is.

I was all set to order hop-up carbon fiber shock towers front and rear.... but I'm hesitation now haha!

I also need to put the camber links on this. I wanted to run it stock (fixed) ... I have, but now it's time to get some adjustability out of it.
I also have the swaybar sets, not sure if I want to do that right away or not as it doesn't seem to lean in turns (pretty stable actually).
