RE: how many engines
2 x Gas Turbines (Wren MW54's)
8 Gassers ranging from a G26 to a DA200
25 x 4 Stroke Glow (Saito & Magnum)
20 x 2 stroke Glow - (OS, Evolution, Supertigre, MDS, Jett & Webra)
6 x Electrics
All get run regularly and 42 of them are mounted in planes that are fully equipped with all radio gear and servos and are flown regularly.
All spread across 3 countries (Good excuse to buy lots and lots of them.
And it's still cheaper to maintain than the wifes 22 Horses, but I don't complain about them because the empty paddocks make a great flying site.
So in total - 2 Turbines, 8, Gassers, 45 Glow and 6 electrics.
But the President of my Home club can beat me hands down, He has at least 75 Glow and 25 Electric - not sure if he still has his gassers though
