Ivan...
You have just described a Pup 150!
This must be the MG of the flying world... British engineered, noisier than the Mondeo (Warrior), limited load carrying ability but one hell of a lot of fun out on those open windy country roads wearing your cravat stopping off for a half of old badgers piss.
Without the spinning weights you will still feel the need to go and beat up the clouds in the evening or Sunday morning.
Can carry 33 stones (remember them?) for 3.5 hours at 100 kts so touring should be possible unless you are all built like Biffa Bacon!
Long range tanks aren't relly needed... after 3 hours you are ready for a pee.
Make sure that you invest in a Pup with all the ADs up to date (particularly wing spars)and only use a single maintainer who is familiar with the Pup ways.
The only problem should be in locating minor parts, but I am hoping that with the retirement of the Bulldogs the RAF maintenance wings should start offloading their stocks onto the market.
Locating the bits can be part of the fun with the reward of flying something a little bit different.
Go and try one... they are a **** load of fun... If you like have a go in mine ... just give me a call sometime.
