This is an Academy Minicraft Lazer, a Hornet knockoff from the 1980's, that I finished restoring a few weeks ago. I picked it up for $20 on Offerup from a guy who listed it as a "Kyosho Hornet" and completed the restoration for under $100.
The chassis is essentially the same as the chassis of a Hornet, and is the same chassis found on the World Engines Rockbuster. This means that it has the odd ribs on the side of the chassis, and well as on the nose. These cars, especially without the body, are incredibly easy to mistake for a Rockbuster or Roadrunner, however there are a few differences.
The first and most obvious difference is the body. It is called The Sly One and was made by Parma for the Tamiya Fox. It fits surprisingly well over the Lazer chassis and I am actually quite fond of the look.
The next difference is the rear oil-filled shocks. "Hopped-Up" versions of the Rockbuster and Roadrunner came with blue anodized rear shocks, but Lazers came with pink anodized shocks. This particular set leaks like a sieve.
The final, and maybe best, difference is the front bumper. All Rockbusters and Roadrunners were fitted with horrendous yellow bumpers, while Lazers had a much better looking black bumper!
These are the wheels that should go on the Minicraft Lazer. The only reason I'm not running them is because I only have 3 of the 4, and two are broken.
Hope this was marginally interesting. Thought I should share my (little) knowledge on this rather rare RC since I had such a difficult time finding information during my restoration.
Ampro Engineering on YouTube did an episode on these , probably the best equipped Hopper out there , there was a ton of clones of them in the 80s , even Traxxas made one called the Cat but theirs cannot have been a clone as Traxxas would never steal ideas from others then patent them
