Latest project, new built RC10GT 96 GTII

[justinspeed79]

Nice build up of parts. I think it looks great, and love the body.

Thanks bud.

what the heck was the Blue flat chassis GT called?

Unofficially, second generation GT.

Everything except the motor mount is interchangeable between the black tub and blue flat chassis. The tub has a steeper nose kick-up, though.

Every flat chassis GT I've owned has been longer than the tub GT.

Nose-to-tail, they are identical. The blue flat chassis does, however, provide 1/4" longer wheelbase.

The front bumpers are not interchangeable either. The new chassis also used several new parts, front bumper, updated 3+2+2 rear suspension mounts with the extra holes extended over the rear bumper, two different styles of nose brace mounts, two different style of lower transmission mounts, two different motor mounts. This is also when they started making the nose brace tubes blue, and when blue shocks came out (on the gt, not sure about others, but iirc, it was the same) and iirc, this is also when the new style tank came out, as well as some other updated (thunder tiger) parts, axles, outdrives,etc.

The short chassis also had some other model specific diferences, rear hubs, one of a kind crank on the ae.12, clutch setup specific to that engine, and maybe more, can't remember.

All versions of the gt,10t, and t2 have the same kick up, iirc, 30°.

The rtr short flat chassis is the same nose to tail, the long flat chassis, rtr plus, team built, factory team, are longer. Iirc it's 11mm.

You go boooyyyy!!!

Most of my memory's of Dave's site just came flooding back and gotta agree that IIRC all of your iirc are pretty much spot on Justin. Pry a few things I'm missing but for the most part you are my gt guru. Liking your new project. Will turn out great I'm sure

Thanks duuuude!

As always, I appreciate your kind words.

You are correct, that was my mistake. I was thinking of the difference in the early vs. late front arms that required different caster blocks, since the late arms were flat, while the inner and outer hinge pins were not perpendicular the early version.

The front bumpers are not interchangeable either.

They are with the RTR chassis.

The new chassis also used several new parts, front bumper, updated 3+2+2 rear suspension mounts with the extra holes extended over the rear bumper, two different styles of nose brace mounts, two different style of lower transmission mounts, two different motor mounts.

Since the trans mount is integral with the rear lower engine mount on the black tub, I didn't feel it necessary to mention that in addition to stating the motor mount differences, nor is the difference between the two blue chassis trans mounts of any consequence.

While the rear arm mounts were changed, either style can be used on either chassis. Same for the nose brace tubes.

The two different motor mounts are true to both the tub and flat chassis; one for PS, one for non-PS

The nose braces of either style are also inconsequential, since the black tub used buggy/10T style chassis mounting of the tubes, and since they are all the same length, regardless of mounting system.

The rtr short flat chassis is the same nose to tail, the long flat chassis, rtr plus, team built, factory team, are longer. Iirc it's 11mm.

I just compared an RTR, an RTR+ and my team built with a black tub. Same length. The RTR has the same slightly shorter wheelbase as the black tub, and a second step/bend in the kick-up to give it the same profile as the T or tub GT.

You are correct about the front bumper/kick up mount on the rtr, I forgot about that.

As for most of the other stuff you mentioned, you are correct, but I wasn't saying some of those new parts weren't interchangeable, wasn't even trying to argue about it, just adding additional information. That's what the "also"'s are for.

I would love to see some pics of your chassis'. I have plenty of tubs and long flat chassis' laying around, and the difference is as obvious as night and day. If you line up the front the flat chassis sticks out about a quartet inch further on back.

And I could be wrong, but wasn't the pin/arm/camber thing only an issue on the early 10T arms?

Just measured the 3 black tubs and 5 blue chassis I have to be sure; every one exactly 14" long. Of the blue chassis, one is RTR (metal nose brace tubes, double bend kick-up), one is an RTR+, one is a team built, and I don't know what kits the other two began life as (also a plastic nose brace mount chassis).

You sure your difference isn't the result of mounted bumpers? They do stick out further on the RTR+/team built/FT blue chassis.

And I could be wrong, but wasn't the pin/arm/camber thing only an issue on the early 10T arms?

Right, which are the same arms that found their way onto the GT until I think 1995, when the T2 came out.

Had to charge the camera a minute, but here ya go:

[justinspeed79]

The early 10t arms were on the 10t only, the gt didn't come out until after they had already revised them, so they are not the same. I don't know if the revised version had the same issue or not, but I don't think they did. I will check one of my early trucks later to see.

And yes, I am one million percent sure about the chassis length! It is not because of the bumper, or anything else. Take a bare tub and a bare flat chassis and gold them together and see for yourself. Although I'm starting to wonder if you would even believe it then lol.... This used to be common knowledge among gt enthusiast, apparently not anymore......

That's nice, but I was thinking of something that might actually be pertinent to the conversation, like a close up comparison shot of two bare chassis'.

I got one better....Blue flat chassis, Black tub chassis, and DS black tub chassis

The flat blue chassis is the longest wheel base chassis of the GT line. The blue has the front extended further fwd than the tub chassis. Now the GT black tub chassis and the DS black tub chassis are different as well. The GT black tub chassis has the longer wheelbase compared to the DS chassis. The GT has two mounting holes for the nose tubes where the DS only has one set.




The GT vs DS chassis. see the extra mounting holes as well as the extra length?


in this pic you can see the steering servo mounting holes are further fwd than the center noseplate screw hole on the GT than on the DS. The blue chassis has no need for the center hole but look at the steering servo holes and you can see they are the furthest fwd when all three are compared.


Hope this better demonstrates the difference in wheel bases between all three chassis.

All of the early GTs I've come across that still had original arms have the "twisted" fronts, and the thick, triangular rears.

That's nice, but I was thinking of something that might actually be pertinent to the conversation, like a close up comparison shot of two bare chassis'.

Seemed more like you were trying to call me out on whether or not I actually had them on hand to measure. No need to go from skeptical to rude, though.

I don't care if you believe me or not. Fact is, I have 8 chassis here that all measure exactly the same length.

[justinspeed79]

Here is a tub on top of a long flat chassis, nose plate screw holes aligned, dimensions are the same from there forward. As you can see the flat chassis is clearly longer on the back. NDS chassis also pictured for reference.

Are we good now?

[USA-1]

Cool Build Justin, Well I have both of these and the blue chassis is longer by a 1/2 inch, I'm thinking the GT Black tub flared out front bumper is what's the difference.

[justinspeed79]

Thanks USA-1.

Nice trucks.
