Super Duper Hotshot with Carbon Chassis.

[toyolien]

This car has been a long time coming for me. In 1987 (I was 10) I received my first Tamiya kit for Christmas. It was a Boomerang. I ran it loads with my brother (who also got one), and this started my passion for RC and Tamiya. Along with it came a 1987 full colour catalogue, which I began to thumb through. Although I loved my Boomerang, I was in awe of the Supershot. Fast forward 35 years, and here I am, about to embark on a lovely Super Hotshot build. 

 

I live quite close to an RC club that races 10th off road on a purpose build astro/multi surface track. I've raced there on and off since the mid 90's, but haven't do so for about 2 or 3 years. I popped in a few weeks ago to watch a race meeting with the intention of buying an RC10B6.3 to do a few races with. But there was a heat or two of vintage buggies that looked much more fun. So, I decided to finally build up the Super Hotshot I bought during the first lock down, and take it to a race or two. I'm not looking at competing with the various Top Forces etc, but am keen to give it a go. 

 

Here's the beautiful box art.

 

 

I then spotted this lovely carbon chassis on Instagram, contacted the guy in Singapore and placed an order.

 

 

The other good feature is that it came with a Yeah Racing M-05 steering set up to get rid of the un-equal length steering arm. It also helps with the bump steer.

 

 

As usual the build begins by separating out the parts bags.

 

 

I got carried away with the rear transmission and forgot to take progress pics, but here it is completed. I'm going to try this TLBM-02 15.5t motor with a 17t pinion.

 

 

Here's the front transmission. I'm using AW grease in the diff gears, and Tamiya Cera-Grease on the rest of the gears.

 

 

I've never been a fan of using the black steel screw in suspension shafts so opted to use Tamiya's stainless steel shafts instead. The were two issues to over come. Firstly, the shaft lengths in the M-05 or TL-01 shaft kits are a little long, so I've had to use some spaces to fill the extra length out. And, secondly on the outside of the rear arms there is a bracket for the lower damper mount. This would be held in place by the screw of the steel shaft. So, here I opted to use a stainless steel hex bolt.

 

 

This allowed me to tighten the bolt up to get the perfect tension to hold the bracket in place. Lastly, I slightly closed the bracket in the vice so it was a tight fit on the arm to remove the slight amount of play.

 

 

On the rest of the car I was able to use stainless shafts.

 

 

Next up, the steering knuckles. I've tried, where possible to use stainless hex hardware, and managed to find some m2 bolts for the knuckle plates.

 

 

Also added some DF-02 universal shafts in the front.

 

 

Front and rear transmissions compete.

 

 

Savox servo borrowed from my TT-02 drifter.

 

 

There's not a lot of space for the electrics in here so I'm going to have to get creative with the space available.

 

 

And, here's the chassis with the transmissions mounted up.

 

 

The esc I'm using is the trusty Hobbywing 10BL60. As usual I'll remove the mutli-coloured wires and replace them all with black.

 

 

After having a play with positioning the receiver and ESC, I settle on mounting the esc on the chassis side. But, I didn't want the self adhesive servo tape collecting dirt through the chassis cut outs so marked the areas to add the tape to with a pencil.

 

 

Spot on.

 

 

That's all for now. Thanks to taking a look, and apologies for so many pics...

Thanks very much. It's probably the best looking buggy Tamiya have ever done (to me anyway).

Me too. I do have an original Boomerang with the box, manual and vintage dual front damper upgrade that's waiting for a restoration.

Probably won't run it much though.

Thanks. Probably be a few weeks to get this completed I'd say.

More progress.

 

I've replaced all the mutli coloured wire on the ESC for all black ones, apart from a single red one for the battery so I don't start a fire!

 

There is not a lot of space in the chassis, so it took a little bit of head scratching to get the esc and receiver in place and out of the way of the centre shaft.

 

Trial fit of the body and wing. It's starting to look good now, I think.

 

I quite like the look of the yellow dampers, however, I know of the issue with the fronts not having enough travel which means the dampers bottom out before the chassis, therefore putting stress on the damper mounts. So, I knew that I'd have to look at other alternatives. Wanting to keep things Tamiya as much as possible I opted for the #54993 TT02b/DF03 dampers. After a little fiddling with the lengths they fitted perfectly. I'll need to have a play around with the oil and springs but initially they feel great.

 

And lastly for now a test fit with the wheels.

 

Next job will be painting the driver figure, and deciding on a colour for the body. One thing I'm sure about is that it will not be box art....

Man that looks soooo good naked with the black wheels!... I'd be tempted to just tint the body panel 😍

Thanks very much. Not 100% decided on paint colour yet. I've got an RC10 B6.3 I'm part way through building. And a Flatgekko chassis in the packet too...

[toyolien]

Finally managed to get some more done on the beauty. I'm not the best painted by any stretch, but the helmet paint came out ok. I'm even worse at drivers faced though....

 

 

 

 

 

 

 

 

And the body is done. Tamiya Corsa Grey with MCI decals. These are the first MCI decals I've used, and although they are not a patch on Tamiya's quality they do the job nicely. Especially for a runner like this one.

I've still got to do the window nets and roof etc, but here is it.
