I was about 12yo and my dad bought me a Cox Baja VW Buggy with a .049.

There was no Tx/Rx. It had settings for small, med, large circles.

You started engine by spinning this big plastic flywheel. Run it rich for slower speed and lean it out for higher speeds.
It started and ran great, but you could develope a huge blister spinning that flywheel.

I got it to haul ass and it jumped outta med loop to large and I couldn't catch it b4 it hit the side of the house.

Those engines would scream!!!
