Hirobo Tomcat restoration without original parts

Post by korreka »

.
I make a restoration of a Hirobo Tomcat [/ b] without original parts; the car had a broken chassis.

Translated from Spanish: https://reparar-cochesrc.blogspot.com/2018/06/reconstruccion-de-hirobo-tomcat.html

The Tomcat (1986) is a 2WD buggy with plastic chassis. Although its design and qualities are better than other brands of similar price, it was never intended for competition, but for the leisure or initiation RC car market.

This car has very good technical solutions: double belt transmission, aluminum hydraulic shock absorbers, adjustable suspension arms, ball bearings, front and rear stabilizer bars, etc.

I bought this car with a broken chassis.
The repair with an aluminum plate did not have the right dimensions:

Image

The seller gave me a lot of unassembled parts with the car.

I dismantle the previous repair:
Image

I made another piece of sheet steel with the right dimensions and angle:
Image

Image

Image

I cut part of the chassis so that the homemade part fits completely:
Image

The part have now the shape and the inclination necessary to adapt to the chassis and the dimensions
Image

Image

Drill holes and make screw wires:
Image

Image

I put the screws:
Image

Image

Image


The screws and the holes of the part that I inserted, I cover them with ABS plastic dissolved in acetone:

Image

I also set up an external BEC made by me with electronic components:

Image

Image

I repaired the old Variator so that it has 3 forward speeds, brake (shorted motor wires) and 2 reverse speeds.

Image

Image

Cleaning and filling the shock absorbers with oil
Image

Image

The motor and transmission are fine:
Image


75% of the work already done
Image

I paint the letters of the wheels in white:
Image


All that remains is to mount the bumper and the tubular body:
Image

The bumper is broken and I repair it with ABS plastic of the same color dissolved in acetone; For this, I put a cardboard mold until the ABS dries:
Image

Image

It's already over; I don't have the spoiler and the front part of the body. I don't have the "pilot" either.

The repair looks strong and it looks good running , these are pretty rare cars so its going to take a while finding genuine replacement parts .
If a jobs not worth doing then its certainly not worth doing well.
A problem shared is a problem halved but an advantage shared is no advantage at all.
