That's a very clean job there WWoodruff!
I've dropped my motor mount aspirations to take on a more complete onroad solution.
I've attached a few jpegs of what I'm working on.
This will be a real world conversion for the Kyosho Evolva.
I'm calling it the E'volva.
It will include a new chassis, motor mount, right side stiffener, a 2 piece top deck, removable battery tray (Losi), spacers for the top deck to accomodate larger battery configurations, front shaft bearing block and 2 new belts (front and side), along with a few other components.
This will allow the racer to run most off the shelf battery packs from 2S to 6S (depending on capacity and C rating). The max battery dimensions should be about 140mm X 48mm X 46mm.
I'm working on cost quotes and the first prototype at the moment and I hope to have kits ready by the middle of summer.
The 3rd image is of an alternate belt layout that I am about 60% done with.
I'd love to hear your feedback and any suggestions you may have.
