presumably you can save a bit of weight by removing the mil spec front seats - stressed to 50 g or whatever - and replace them with flimsy civil spec ones.
BTW I see from this month's Flypast mag that one of the Dogs I used to fly has gone to France.
2 questions:
1. does this make them a Frogdog?
2. do the Frogs bother with the main wing spar mod?
