Sorry for the delay regarding the French Marmon Wasp.
I have been in transit back from work.
Yes it is small and a bit of a head scratcher.
The wheel base is 80 mm. Wheels are Vintage by Penelope pit stop.
The motor is an FF 18k. Hot glued in.
The rear axle bushes are attached to the body directly.
The front axle / chassis is scratch built brass, the drop front axle is solid brass square stock with SCX round axle bushes soldered on
( I think the look was pretty close) supported by leaf springs also shaped from brass flat stock that are attached to the resin body chassis rails (super glue).
The rear view mirror was a huge PIA. Brass to try and protect the model ( sort of roll bar).
Yes it is digital, yes it has a mag. Sticks well enough to be practical and looks great on the track.
I hope the pics help.Cheers
