i did it for my MN45 (FJ45)..i put wpl dual speed gearbox and the black 370 strong magnet,it crawl!! YES the low speed is good! but i think must add some weight or depend the tire..it awesome as mini scale crawler
Looks great! A little paint and weathering and it’ll be awesome! Besides the frame and running gear is the body metal? You did a fine job photographing the build and the test drive.
WPL products come with a lot of metal parts. But this product is good enough. But when you assemble it, you have to assemble it so that the gears are easily bitten.
