X-mailer: iolo System Shield 4.0.3.107 Not so fast, boys. In the '30s Packard developed and (I think) certified a diesel radial aircraft engine and someone certified a counterbalanced (with a god-awful lump opposite) a 1-blade for (at least) a Piper J-3 Cub with an A-65. Neither set the world on fire, but there you are. I, personally, am intrigued by Paul Lipps' investigations. A good precis of which is available in Contact! magazine #88.5. Special issue, available.

It produces thrust one side of the airplane only, left, top, right then bottom. And that doesn't include the asymmetric effect of angle of attack.The airframe will oscillate in a corkscrew fashion, what a horrible prospect I can almost feel my teeth rattling at the thought of it! 2 stroke diesel?

Hi everyone! Today, at 12:25 LT on EHHO, PH-DIY made his first flight. Conditions were vulcanic ash, 17-22 KN head wind (straight on the runway). According to the test pilot, the PH-DIY flies beautifully, straight and balanced, can be flown hands-off, with a very slight tendency for left (but this can be attributed to the asymmetric load). Only the rudder seems to be a bit out of balance: there is always some "right rudder" required. A trim tab would solve this. This needs some investigation. Stals: The stall is, clean and dirty, benign. Some buffetting, and then nothing really happens, he just parachutes down. Absolutely no wing drop. "Like a Cessna" according to the test pilot. Stall clean is at approximately 50 Knots, with full flaps it is 42 knots. Performance: The pilot was amazed at the performance of this airplane. Climb was 1500ft/min with 80 knots, with the power to 100% (not 115%). Cruise was with 4200 rpm and a manifold pressure of 28 good for 120 knots IAS (the airspeed indicator has been calibrated to a maximum deviation of 1 knots). Conditions were somewhat turbulent, but performance data was verified in a sequence of tries (because the pilot had some trouble to believe this data, he tried it a few times at some distances apart to rule out local updrafts). We have had some temperature problems on the early ground runs, but although the temperatures on the ground still have a tendency to rise, during flight the temperatures were actually quite low (this was with the cowl flap 3/4 open, I asked the pilot to leave it at this setting to keep things simple and comparable). Quirks: The PH-DIY needs constant right rudder. If anyone has a good idea what the cause can be and/or what to do about this, let us know! In cruise, there is some down trim necessary. Trim setting is not in the middle of the scale. I believe that this is a common thing, but I have not yet checked the Europa forum archive for this. Comments: After some horror stories of Europa's that flip upside down on the stall, we are very pleased with the benign stall characteristics of the PH-DIY. The performance data is better than we expected, and we will of course repeat the tests. (We have Fred Klein's wing root fairings, a radically trimmed down and optimized cooling duct, and of course this "can't be true" 2-blade high twist large diameter prop, so we expected performance to be on the good side of the scale, but this is more than we accounted for). Well, tomorrow we will give the PH-DIY a thorough check, so if weather cooperates we will saterday fly ourselves (first with an instructor of course).

Hi everyone! Today, at 12:25 LT on EHHO, PH-DIY made his first flight. Conditions were vulcanic ash, 17-22 KN head wind (straight on the runway). According to the test pilot, the PH-DIY flies beautifully, straight and balanced, can be flown hands-off, with a very slight tendency for left (but this can be attributed to the asymmetric load). Only the rudder seems to be a bit out of balance: there is always some "right rudder" required. A trim tab would solve this. This needs some investigation. Stals: The stall is, clean and dirty, benign. Some buffetting, and then nothing really happens, he just parachutes down. Absolutely no wing drop. "Like a Cessna" according to the test pilot. Stall clean is at approximately 50 Knots, with full flaps it is 42 knots. Performance: The pilot was amazed at the performance of this airplane. Climb was 1500ft/min with 80 knots, with the power to 100% (not 115%). Cruise was with 4200 rpm and a manifold pressure of 28 good for 120 knots IAS (the airspeed indicator has been calibrated to a maximum deviation of 1 knots). Conditions were somewhat turbulent, but performance data was verified in a sequence of tries (because the pilot had some trouble to believe this data, =C2-he tried it a few times at some distances apart to rule out loc al updrafts). We have had some temperature problems on the early ground runs, but although the temperatures on the ground still have a tendency to rise, during flight the temperatures were actually quite low (this was with the cowl flap 3/4 open, I asked the pilot to leave it at this setting to keep things simple and comparable). Quirks: The PH-DIY needs constant right rudder. If anyone has a good idea what the cause can be and/or what to do about this, let us know! In cruise, there is some down trim necessary. Trim setting is not in the middle of the scale. I believe that this is a common thing, but I have not yet checked the Europa forum archive for this. Comments: After some horror stories of Europa's that flip upside down on the stall, we are very pleased with the benign stall characteristics of the PH-DIY. The performance data is better than we expected, and we will of course repeat the tests. (We have Fred Klein's wing root fairings, a radically trimmed down and optimized cooling duct, and of course this "can't be true" 2-blade high twist large diameter prop, so we expected performance to be on the good side of the scale, but this is more than we accounted for). Well, tomorrow we will give the PH-DIY a thorough check, so if weather cooperates we will saterday fly ourselves (first with an instructor of course).

Congratulations Frans Anyone completing a Europa deserves a medal in my opinion. Great word from down under.
