OK! So keeping it to all things Mini
Ooooh! I just loves WHEELS oooh aaah. I can see where you are coming from Giz-man and without getting too technical for those that aren't experienced in the whys and where fores and decide that a couple of old Bike Wheels will do the trick, any Plans this sight recommends should probably Stress that Bike wheels have a tendency to collapse under the Side Stress exerted by strong winds. Tassiefubar shows this in a photo. Although this looked relatively harmless under
those conditions what would have happened at Great Speed, 80kph plus???? None the less no matter what we do, decide, stress etc there are those that will, regardless, go their own way. Hay! When they first started Hang Gliding there were those that went with Black Plastic, Bamboo and Duct Tape



and a few busted limbs, cuts and Bruises.
Go back even further and they even tried frames with Chicken Feathers. Evidently those failed as Chickens can't Fly properly.
We all have to learn somehow.
400mm Max Dia, Wheels of sufficient strength to resist collapse and or approved by Club officials should be sufficient.
It then becomes up to the individual club as to weather a chosen wheel is Safe enough to operate under their Banner. As a Loner it is not up to a club to stop me from operating a dangerous machine on open venues. Clubs can guide and advise but can't lay down the law to none members.

PS; Thanks Vic, It just appears larger in the pic's. The Razor would fly on those 20" wheels.
