TR-6 or BR-6T?

I vote for BR-6T.

I vote TR-6 (Truggy Racing 6) ! I thing Intech must inverst in this category. Here in Brazil we got lot of Truggy races and we love it.

About my Intech BR-6. I realy got problems to got my buggy on a dry and dusty track, with lot of bumps. I saw that Intech got minimum downstop if we put the shock more inclined. I want a lot of downstop for this kind of track and I want it very inclined to make the shock more progressive and smoothly.
I canīt do that.
So I will try Fioroni Towers for Xray 808 to get more downstop, or put the rear shaft on the front.
I still got the problem about shock compression. The Intech Buggy got stiffer when I compress it (Front). It cause loose traction and low weight transfer for the front when I break. It hooks and turns when itīs very bumpy. I have to get the shock more soft. Handle better bumpy track.
When the thack get more grip, it feels great. But canīt configure it to a loose track.
I compere the compression front movement between Intech BR-6 and Mugen MBX7. The compression on mugen is lot of soft and continued, the Intech compression front itīs getting stiffer and donīt get the end of the travel. It realy got too stiff. It cause loose traction and less weight tranfer.
How can I fix it? Some one of you get this problem?

Thanks

What insert are you using in the B-plate or for kickup?

Ben Burtle 03-05-2013 12:08 PM

Try the zero position on kickup and the upper row of holes on the shock tower.

I had the same issue when I tested on a very bumpy and dusty track. I changed my pistons and springs and it seems very good now.

Greg B 03-05-2013 12:27 PM

I have removed the camber links, tie rods, sway bars and shocks and the car still had the mentioned bind in the front. You can see as the arm travels upward it does pull the tires towards the inside.
Installing the (1 up) insert for kickup helps it a little but it makes the car a little wild for indoor racing with gobs of traction. I'm yet to run the car outdoors but under dusty conditions I doubt this is your problem. The car will transfer weight towards the front as long as your running full droop in the rear. I'm still trying to figure out the front bind myself but it's only noticable to me while on the bench. Doesn't drive like it at all.

I use a Aluminum Caster block 12š and a insert 1.5 up on B-plate = It means like 19.5š Total Caster

Thanks for your response. When I got full downstop on the rear, I still transfer weight for the front, but if the front are too stiff in the and, The weigh donīt be transferred the total amount, just because the front resists this movement. I got loose front traction on that condition and the car get too bumpy on a bampy track.
I will try that you say. I always drive on Outdoor tracks.
Maybe I do one little video to show it.

Thanks a lot! Iīm still searching for the solution.

There is no bind, that is tire scrub you are feeling and it is normal for short arm suspensions. Feel a Losi/Agama/Serpent/JQ/Xray front susp to compare.

As you can see in the photo, the car is resting on a wheel wrench which is 40mm ride height with no front shocks. At this height which is what I had to throw under it at the time, or racing height of 28mm the result is the same. When I removed the wrench and let the car drop you can see by the line on the pit board how far the tires move towards the chassis. Shock position has nothing to do with it. It's simply built into the car. Some cars have it and some dont. As you push down on the front of the car the added weight and pressure that you're applying and the tires gripping the surface makes the front of the car feel tighter the more you compress. On the track, it's not noticable as the car changes directions and moves about.
Dunno why the pics are sideways but you can get the idea.

VPProUSA 03-05-2013 01:16 PM

Yes, put rims on with no wheels. Set on a smooth tile surface and push down. There should be no tighter feeling then because the rubber is not garbing the ground as the tires move inward.

VPProUSA 03-05-2013 01:16 PM

I prefer tire scrub because you can run thinner oil and still not bottom out on jumps because the susp gets stiffer as it compresses.

Ok. How can I get more consistence front, without feeling that? I just compare it to other cars. In The older Intech BR-5 got the same problem. I made one new hole on the tower raising the Center of gravity (below the other three) and it works on the older one. The car sims to get more smoother shock compression, but also got the car too smooth.

OK I will try you recommendations! Thanks a lot about all of your attention!

Orcine Abreu 03-05-2013 01:25 PM

Maybe adding more bump stare, reducing the movement of the tires inwards. This maybe works?
