ok, Thanks for all of the replies. I was looking for bike tires by the shed last night and found our old riding lawnmower trailer.. It will work and if not the child carrier will. Skynard, We will not be carrying our planes when they are put together. They will be wing and fuse. I think in the trailer could fit 3 planes at least which is fine. I think we could almost haul it down there with the lawnmower, except we have to cross one big road, which is a 3 lane,So the bikes will have to do.

I think i will get some Conduit, and connect it to my bike, and then connect the trailer. With my bike, it shouldn't be bad to do... And we can switch out who hauls the trailer...
