Two problems I can think of:

As mentioned in other replies, I don't think you can use an experimental
plane for commercial (rental) purposes.

What if the pilots renting them have a variety of minor accidents due to
inexperience in make and model. The companies might get market
exposure, but it could be negative.

A perhaps better idea would be for Sparrowhawk, Apis, Silent, etc. to
loan a glider to the big soaring sites (Bermuda High, Seminole Lake,
Minden, Turf, etc.). That way many people would rent these gliders
and the glider manufactures would gain a broad exposure.

Is this not a good way to build market presence?
