Every VP1 is different.
The one that Stik talks so lovingly about was originally part owned by a 18 stoner.
He started flying it when he was 12 stone and by the time he reached 16 stone the VP1 would only support him or fuel in the tank, not both.
The best weight for the aircraft was less than 12 stone and one of the lighter owners used to regularly fly it across country from Suffolk to the PFA rally every year.
So its worth finding out what fuel and pilot it will carry and still climb reasonably.
Carb icing is a nightmare. ground run it with the cowls off and you will see frost forming in seconds on the inlet manifold, its worse with the throttles at idle so use carb heat on the ground but not for takeoff!!
Owned wisely they are a lot of fun and owners are very loyal to them, but they are less forgiving than a PA28.
