Design Assets:
This RC21 [Radio Controlled .21] had it’s roots in 1982, when Honda GP Racing re-entered the circus with a V-3 two stroke race bike.

I was aware of the smaller Eleck Rider R/C motorcycle in 1980 and thought it would be nice to have a larger scale GP bike. It was many years before I had the knowledge to make all the specific parts, mainly the rims and tires, also the mouldings for the fairing and related parts.

Larger scale models allow very great detail with similar materials, as used on full size race bikes.  Further development will be done this summer.

I am very happy with the scale effect this model radiates.  My Salute to the Great Freddie Spencer!
