also PVC get really brittle in the cold which we know Alberta has.
This is so far off your long stated design goals that you should just rethink them
i.e forget quad go for 3 wheel, one in back and 2 in front, forget suspension and use big tires, super light outside covering, and so on. Good luck
This was me rethinking my plans, sir--using PVC pipe because I can't weld.
And besides, if I go 3 wheel now, the guys at Cranked are going to be super-annoyed: they just spent a
joyous weekend last month lacing up the wheels for the rear end.
(Note: On another forum I'm on, the forumites there use green to denote sarcasm.)
But I am seriously considering not using suspension, like you suggested.
And I'll make a confession: I've more than just seen videos; I have seen this in person--someone in a nearby town owns one. Their kids seem to like it.
