With respect back Kip
Brian R, Brian W and myself have all had very costly repair bills due to these engines and there headgasket blowing capabilities also all craft were fitted with the osprey cooling system you speak off when the problems happened. I know the down falls of fitting a engine that needs to rev to 4500rpm to get 1st lift, my craft was one of them the operating rpm was 4000 to 5500 rpm and would fall of hump if the rpm fell below this limit thats why I started to experiment with different fan setups and modifcations to the plenum,air feed holes and a few other things.
I am now happy the way my Osprey 5 goes and find it meets my needs it now lifts at 3000rpm and this has taken a lot of stress of the engine.
I am not trying to put people off buying one, just pointing out you really need to check the thing out properly before anyone hands over the cash.
Remember 3 years ago 2 osprey 5s were up for sale on apollo duck ,the asking price for 1 was £22500.00 and the other was £20000.00 and it blew the head gasket in 10 min`s at the training day in front of the trainers.
£8750 seems like a good price if the engine is upto the job for the 5 in this months mag,
I dont try to pull the wool over anyones eyes because I am not a sheep
