My Dad & I went to Heathkit in KC back in the mid 70's,, & he picked up an elaborate TV kit & bought me a Multi meter kit.
That was the first circuit board I ever soldered.
My Pop's said that meter still worked all the way up thru the late 90's.
Heathkit stuff was awesome, & just about bullet proof.
That Hill topper is cool,, & I dig that they got the Guy sitting on it in the ad, having a drink in his hand.
Also like the body styling on that R/C car.
Don't think the Futaba looking servo, servo saver,, & tie rod components,, were original on that though.
Those look like upgrades from the later 80's.
