Style is not exactly a prime consideration when your "ride" is a Radio Flyer.
I want to make this FWD to make things simpler. The wagon is similar to
this, minus the canopy. When hooked to the XT8, it doesn't turn all that well; it kinda drags the front end until the tires decide to pivot. So, I figured I'd redo the steering scheme and provide power in one shot by making it front wheel drive.
Since the front end of a truggy has all the basic components to do this, I figured I'd use it for the base. It won't have suspension (although I may add something for this, but that's a future mod). I might need to find a way to lengthen the driveshafts for a wider wheelbase to ~19" total (the long center sliders from a Revo?) and then find a way to attach the tires to handle a 17mm hub.
The XT8 I'm using now is a bit "twitchy" at startup since it's geared for ~35mph. The 5s battery and 1717 motor are always stone cold at the end of even a 5 mile run, but the ESC running at minimal throttle tends to get warm.
Since I want to go a max of 10mph, motor choice should be easy. Geared 46/12 and with a truggy diff, a typical low kv outrunner on 5s would get my desired speed. But since it would need a special bore pinion and motor mount, I think a regular inrunner (Medusa 36-80-2000) on 4s or 5s using a Summit transmission in low speed geared 62/22-18 should be adequate.
