Mary, to me a Chippy with a flat engine that turns the wrong way and sounds like a VW Beetle and isn't aerobatic any more is an abomination.
It may well be a practical tug, but it is no longer a chippy. And because someone took a Chippy and converted it, it means there is one less real Chippy around.
And you could never think of it as a little Spitfire.
Did I mention they are non-aerobatic?
So compared to a 'proper' Chippy, it's lost it's looks, its character, and much of its raison d'etre. Just to tug gliders.
Like taking a 'D Type' Jag and nailing a wooden 6-seat cabin onto it and fitting it with a commercial diesel engine so you can use it as a minibus!
Crass vandalism! Nothing less!
If you want a minibus, get a Transit.
If you want a tug, get a Super Cub.
