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:
The seller gave me a lot of unassembled parts with the car.
I dismantle the previous repair:
I made another piece of sheet steel with the right dimensions and angle:
I cut part of the chassis so that the homemade part fits completely:
The part have now the shape and the inclination necessary to adapt to the chassis and the dimensions
Drill holes and make screw wires:
I put the screws:
The screws and the holes of the part that I inserted, I cover them with ABS plastic dissolved in acetone:
I also set up an external BEC made by me with electronic components:
I repaired the old Variator so that it has 3 forward speeds, brake (shorted motor wires) and 2 reverse speeds.
Cleaning and filling the shock absorbers with oil
The motor and transmission are fine:
75% of the work already done
I paint the letters of the wheels in white:
All that remains is to mount the bumper and the tubular body:
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:
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 buggy in action:
