lbarnes Posted February 16, 2009 Posted February 16, 2009 Hi JL,Do you know how Fish gets the C of G right with the 912 engine as it is around 15 Kg heavier than a 582? Cheers I saw him doing a super drifter conversion some years ago, he extended the boom forward and sleeved it. I recall he also inserted an ally "I" section inside the boom where bending stresses would be at a maximum.
Guest Juliette Lima Posted February 17, 2009 Posted February 17, 2009 Hi Bilby, Apologies for the delay in responding. Ibarnes has basically got it right , ie, an extended boom, lots reinforcing (extra sleeving) around engine supports and undercarriage....plus a lot more I specified. Fish told me it is more trouble to modify an existing Drifter than to build a new one....(ie 912) There is extra leg room in the front and that suits me fine as I felt a little cramped in my previous certified Drifter. In respect of C of G, I can take off fully laden two up, with 70 litres of fuel, (7 hrs flying...Please don't state the odvious, as I now have about a three hour duration) Trim the aircraft for 1200 fpm climb.....take hands off the controls and there is a very gentle easing of nose down. Fish tells me this is how it should be. A lighter pilot, say 70kg ,might need a bit of ballast in the nose. Hope that helps. Cheers JL
skeptic36 Posted February 19, 2009 Posted February 19, 2009 I can't think for one second why I would pay $60K to play piggy back in a trike!!! WOO-HOO, I've been over to Porpunka today to do my passenger endorsement. I think I might spend the weekend piggybacking my wife around in the trike ;) Regards Bill
bilby54 Posted February 20, 2009 Posted February 20, 2009 The 912 engines are now around $20,000 so there is a big chunk of the cost. Cheers JL Have a chat with with Bert Floods but you will find 912 A's (80 HP) at nearly $30,000 inc . No wonder Jab 2200's at $14,000 are begining to take hold!!! With the current economic situation starting to bite, I have difficulty in paying that much no matter how good the opinion of the engine is. Seems a bit like Holden and Falcon to me. I will probably get a thread going in the engines section to find out why everyone likes 'their' particular engine brand.
winsor68 Posted April 30, 2009 Posted April 30, 2009 Have you ever tried telling a motorbike owner that he could have a got a nice little car for the same price ?Cheers John Have you ever tried explaining to a car driver that the bike you buy for the price of a cheap car gives you motorcycle performance on par with a Lambourghini? 0-100kmh in less than 4 seconds....300kmh top speed....Not for the feint hearted...but then again neither is flying. Lol Lol Lol to the car drivers...
