The ProPulse Story: RadioShack’s 1:18 Racers That Missed the Catalog Era

October 23, 2026

If you go looking for the ProPulse in a RadioShack catalog, you will not find it – and that is not because it was never sold there. It is because of timing. The great run of printed RadioShack catalogs ended in 2005. The ProPulse line arrived around 2006, sold through the stores and the website in the years after the catalog era closed. No catalog pages, no flyer ads, and when the maker’s own website disappeared, even the manuals vanished with it. What survives is the hardware itself – and the paper that came in the box.

ProPulse was RadioShack’s store brand for a pair of 1:18 scale ready-to-run racers built by Megatech International of North Bergen, New Jersey – the same cars Megatech sold under its own Megapro name. The PRO-B100 is the buggy; the PRO-T100 is the truggy. Both are 4WD, both run the 370HT high-torque motor, and both measure 8.7 inches long by 6.8 wide on a 6.1-inch wheelbase. In period they were quick, cheap, and everywhere. Today the cars turn up regularly – but the boxes, the guides, and the factory hop-ups almost never do.

That is what makes this shelf of our store different. We hold new old stock, open-box examples of both starter kits – the B100 and the T100 – photographed from every side, because the box backs are documents in their own right. The T100’s back panel prints the factory option list with the old RadioShack-style part numbers that appear nowhere online: the Twin Motor Conversion Kit 60-9514, the High-Speed Motor 60-9507, tire sets 60-9500 (all-terrain), 60-9503 (dirt) and 60-9504 (slicks), and the Battery & Charger System 23-740. The manual’s tuning pages add 60-9512, the Titanium Turnbuckles and Servo Saver Kit.

We also hold the printed ProPulse User’s Guide for the two starter kits – a document that, as far as we can find, exists nowhere on the internet. It anchors our Manual Library, where we are gathering the paper that keeps these cars alive.

And the hop-ups are real, not just box art: the Twin Motor Conversion Kit itself, new in its blister. We run one on a shop car with the rare aluminum dual-motor conversion, and a second car carries the Megatech brushless conversion – both get their own articles as this series grows.

The ProPulse missed the catalog era. It does not have to miss its documentation era.
