Hey Mike,

Yeah, with the stuts, you will need a low one alright.

I look at that and draw up something for you real quick :)

Here you go :)

And while I was at it, did one for "generic" gliders.
I tried to keep it as low as possible, as I think, in my view, the trolley you see are too high. Lower, more stability I think.

So, who will be the first to build one?  :D

Ok, had a bit of time this week, end, so I did this :)

Does not look too bad! Have to find wheels for it, and I'll bring it with me at the Cork event as we may do aerotowing to give it a try  :)

Well, not with the kind of weather we had Andy!  :'(

Anyway, trolley built and approved... On the bench!
Very little modification to make it even better, and off we go :)

this ka3 is no longer .....sadly :(
tried to aerotow , and not enough experience on my side
pulled up to much , snapped the line at all most vertical at about 6 metres up
wings all good and rear of fuse
so will have to build new front end 😫😫😫😫😫

Sorry to come here after the action, but I don't understand why you need a dolly for a Ka3 ? I don't understand the problem with the wing struts ? :-\
Most of times this sort of old gliders take off very easy and quickly, few meters, with a guy maintaining the wing horizontal for take off...

I wish you courage for the repair...

just wanted to make smoother as our field is a bit bumpy
the trolley worked fine , it was me who over imputted and pannicked , from behind it looked liked a dolphin rising and diving
we live and learn , repair is under-way

If your field is "bumpy", it's another reason not to use a dolly... Your dolly bump on the field, the glider bump on the dolly, twice the effects ! :-\

Problem solved!  ::) ::)
