Towplane performance

Our operation has started the hunt for a new towplane.
The main criteria is that from our 2200ft strip at sea level we need
to have a two seater (janus) "over the fence" at 300ft in still air.

What would you recommend?
Dont dwell on purchase cost but rather performance/running costs

We would consider
a) Used
b) New
c) Experimental/anything else.

Thanks for your thorts.

Roy,

You say that you´re looking for a new towplane! What type did you operate so
far?
A 2200ft strip at sea level and 300ft over the fence in still air with a
Janus in the tow sounds like a challlenge!
I was towed by many different towplanes, but there are very few which can do
that reliably!
One, which can do the job is a YAK-55 though....however, not the usual kind
of towplane!

I tow with our clubs Husky and on our 1600ft strip (1950ft above msl) we are
talking more like 50ft "over the fence" (and much less in the summer) with a
DG-1000 in the tow.

Good luk,
Markus
