Funky gearbox or motorplate or whatever this blur plate looks like in the background. Even original dirt and debris on it? So cool

I feel bad for not having given it any love since I got it but I will certainly give it a good clean. Want to keep it in the same spec though..

It's a machined gearbox case. Very different from the 211X/Dyna Storm inside. It dates back to 1991 when TRF/Tamiya did a custom gearbox for the Astute. Main differences from what later became the 211X gearbox are;

* Larger diff gear, larger bearings
* Smaller idler gear + drive gear
* Main shaft has a metal gear, and this seemed pressed onto the shaft. Hard to tell if it's aluminium or steel but I would guess either steel or hardened alloy (showed no wear)
* Idler gear shaft is integrated / lumped into the plastic gear so that the axle spins on bearings, rather than the DS setup. Seems completely copied from the RC10 team car/Stealth gearbox
* Diff outdrives are one-piece. Weighs a bit more than the Dyna Storm/211X setup but simpler and less parts.
* Designed for a Super Astute slipperclutch but with extra disc springs, very simple design compared to what was to follow..

I am not shure, thinking about I would finda former teym driven Tamiya, probably I would leave the patina as it is. No shame for it, its hisorical debris

Great informations about the gearbox. I can imagine there are still so many parts and prototypes I havent ever heared about.

Yeah, I know. The 1991 TRF Astute still has its chassis identification sticker from the Worlds at Detroit, I'd rather leave that one as it is  Also have the tires that were used.
I will eventually setup a dedicated vintage TRF page where I'll try to document everything I know about my cars and others, put together some sort of timeline.

Please go for it! That would be so great. So far there are only two pages I know which have interesting content:
RC Classics & Moderns by Black Hole Sun
rcfan.net

and probably this one:

Hi guys. For some reasons I am bound to my flat for the next 10 days... dont ask.

Anyway I cant continue to make the metal parts yet but I thought maybe its a good moment to think about eletrics.

 

I will definitly keep the TRF Acto, it fits fine from periode and power. But I dont have any periode FET servos and also I want to use all my models with 2.4Ghz.

Now this is a mix of old, medium and modern electronics : ) The servo is brand new.  Last item I have to choose is the ESC but but shure which.

 

• GM V12 World Edition
• GM V12 World Champion (+ Reverse)
• Kopropo Twister Hara 2.2
• Novak Tempest Pro Hyperfet 2
• LRP LE25 AMS (which I think is no good choice)

So what do you guys suggest?

I would go with KO as they've partnered with Tamiya in the past for ESCs

Good point I have not thought about. Uff, bur after a 4 hour pain session the GMV12 is installed.

But now the funny part. I decided to use the V12R (reverse) first because it can help if you are alone on the drivers stand and you have hooked in somewhere.

ESC tested after I bougth it a half a year ago, fine. Tested bevor installed, fine. Testrun -> failed.  It was just the time to die. Somehow I have to admit, going brushless with mid level gears are fit and forget. Vintage electronics has its charme and for shure some unique driving, but yea...

So I took the second V12 (forward only) and installed it all. It was fun till a certain point, but I finished it and had some beer, hurray.

 

Maybe swithching to the Kopropo... or BL.

Posting here as well as into the other topic, just to have it complete.   Early and late version of TRF211x. Both replicas.

Absolutely perfect  well done!

is that a Parma Impulse body on the right car? Been searching for one so long..

[Collin 2052]

Thank you Sir.
 

No. I have not found one and if, it would be a shame to use it for a runner.

Its a Penguin replica of a Losi SE Pro and it fits perfect from its shape.

Excelllent work again! Congrats Tom! Real Tamiya history! They really put a lot of effort in these times into getting back into compettitive Racing. So interesting to see these 2 different concepts beneath each other with the differencies!

Need to check the other thread! 

Kind regards,

Matthias

Last bits done on the TRF211x replica. Gearover is not perfect with its tiny fold but I dont know anyone who can do them in better quality. Motorplate fits very nice, the gap is even all around the motor. Finalized this in the last week of the year. Only missing, 3 pcs m3x6 TI screws for gearcover, run out of them.

Happy holidays guys!

Looks Ace Tom, cool appetizer for the end of the year!!

[Collin 2052]

Thank you... Maybe one more, the year is not over yet.

This paperweight is for my desk. Not only for loveletters, can also be used as a jig for motorguards.

To the left, TRF211x dampers and beside the mini sleeved dampers made for TRF211x mk2 and TRF411x.

The raw silver minis will be mounted on my Kumamon MidMotor Dyna Storm. The other set will get a anodized coating to fit both other replicas.

I have to admit, all this went through the roof, way further then I ever planned or expected. It all started with that broken dyna bulkhead on my TR-15T some years ago around that time.

Thanks to all supporters, in- and outside the TC bubble.

 

PS. Signed in TC 1th january 2013. Ten years anniversary soon.

Such a work of art. awesome!

The dampers are Ace Tom!

If you really pull the trigger some day and do the replica of the 411x, that will be awesome! Thes prototypes are so uncommon and unknown...

It could be done, it all comes down to how ambitious you want to be. The hardest parts, from a purist perspective, will probably be the outdrives, the layshaft pulley, the front gearbox plastics (particularly if sticking to the cog-based belt tension setup) and possibly the drive belt. I'd say all the rest can be done, either through machining nylon or aluminium, or borrowing stuff from other cars.

Small stuff that you can't spot from the outside can of course always be simplified, such as hex or square shape (outdrives + pressure plate) instead of splines, but it'll still be a ton of work. I have all parts if somebody would be ready for a serious attempt, but that's gonna be one big project. And it'll require lots and lots of Dyna Storm hardware for whoever wants to complete their replica..

pa12 nylon prints are so good now, no problem with any plastic parts. Suspension arms machined from nylon or delrin. I can draw all parts in 3Dmyself but the real deal is to find someone doing machining for outdrives with correct splines on it. Also the same spline on mainshaft. The guy who made the dampers is really good but it cost me so much time to communicate things well. THE point is the price. Low parts numbers are on high cost, really high cost.

Drawing parts and technical drawings, research, testprints, corrections, communication with manufacturers, this all eats a lot of time.

But luckily I just went through a ~600 hours project which will make a simple 1:1 replica/clone look like a weekend job 

To be honest, doing really good replicas cost a lot of time and even the 411 will be a challenge, but no problem at all. Thanks to an ex-driver who sold all his old cars I can get my hand on an original 411 to do this project, soon. I am most afraid of disassembling because we all know, old ABS is brittle a.f.

But shure at the end it will be "only" a replica. Surfaces for example. I spent a lot of time trying to immitate the ABS look but no success. Also with machined parts. Lot of TRF parts are rough surfaces, also sleeved dampers surfce is so fast and loppy machined for example, so you have to tell your cnc guy to make things "bad" in a good way. You can get very lost in this details.

At the end it does not need to be a forgery of a painting, but a pretty nice imitation, probably even better because of chosen materials and so...

Jep, this will be probably my last goal on a very short list of RC projects. Luckily I only observe one chassis, but in all variations. Long live the Dyna Storm. Yeeepeeee!!!
