Even though I was very tempted back in 1985, I never owned an original Hotshot, but when I recently discovered Grahoo's Hotshot build (http://www.tamiyaclub.com/showroom_model.asp?cid=65482&id=418) I wanted one badly.
I love putting 21st century materials, components and parts into older RCs and Grahoo's mods are in my opinion just pure perfection, especially since he managed to keep the typical Hotshot look.
So, while I was looking for a used Re-Re, my own build started in my head and I came up with the following plan
- replace the tiny chassis with something more accessible out of carbon fibre that holds shorty Lipo
- fix that aweful bump steer
- just like Grahoo, I want dual shocks, but not the Super Hotshot look
- increase wheelbase to today's standards, as I like the stability of modern buggies
- put some modern wheels and tires on
- find some universals and other bits and pieces for more stability and performance
- get some mild brushless power
Still without a car, I ordered a lot of parts from or for various Tamiya models, hoping that my plan will work out We will see...
Anyway, eventually a barely used, but heavily greased Hotshot showed up, fully ball raced and with a hex conversion and 2.2" wheels and tires already done. The wing has been replaced as well, but I will need a new body set anyway.
As I was prepared, the first mods were simple bolt on jobs, starting with the Radshape bumper, which looks so much cleaner than the huge standard item
Equally easy to replace: the front knuckles. Since I found that blue is the color most aftermarket alloy parts have available, I chose the Yeah Racing knuckles for a TA-01/02.
And while the front was taken apart, DF-02/03 universals got installed as well. Unfortunately, I was only able to find the Tamiya hop ups, which are 70mm and a bit too long. I might replace them later, if I find alternatives.
While waiting for more parts, I wanted to see if my ideas for the rear shock setup will work out and assembled the 60mm Yeah Racing shocks, build a temporary mount and started my version of a new push-rod system.
Using GPM rockers for a TA-06 (fitted 3x8x2,5 bearings), at least I was able to confirm that everything actually might work To my surprise, all parts bolt right on existing mount points, without measuring a single thing.
At this stage, reviewing some of the pictures you see here, I noticed one big issue! Things got a bit too colourful for my taste.
Of course, Tamiyaclub saved the day and I found this great thread about dying plastic http://www.tamiyaclub.com/forum/index.php?showtopic=66964
After a pack of RIT Dye and a ruined fondue set, all red plastic parts are now a friendly black
So much better...
Some of you might have noticed, that I had some blue plastic bits in the pot as well... Those are from a Boomerang suspension, as I wanted to have a bit more toe in in the rear.
Alright, this is where I am for now, after one week. Next steps are designing the new chassis, finish the push rods, and so much more... Progress will be a bit slower
