Hart" Subject: Kolb-List: Father's Day Flight Kolbers, Had a very pleasant flight from Winchester 35 miles south to Connersville, Indiana to Connersville Airport Father's Day event. Saw a few of the Hargerstown, EAA Chapter members there. Some antiques, may be ten experimentals, one life line helicopter, but mostly ga aircraft flew in. The FireFly was the only ultralight vehicle. Lots of kids to look at the FireFly and parents to encourage to let their kids learn to fly. I have made some changes to the air fuel mixture control. I kept moving the high pressure reference point around to try an find a stable source. But things would happen that I could not figure out why they happened and so I installed a positive dynamic pressure probe in the carburetor inlet. This has proved to be a better pressure source in that as one retards the throttle or opens the throttle the positive pressure follows the throttle position. I was worried that may be the pressure could become too high and run the engine so rich it would quit, but that has not been the case. For what ever reason, and I have not completely rationalized what is going on, but I can change throttle settings, and I do not have to readjust EGT. Also, if I nose the FireFly down and unload the propeller, I do not see and EGT increase. It is very stable. Burned 1.81 gallons per hour, cruising at 50 to 55 mph gps and burned 2.61 gallons over 70 miles with two take off and landings for 26.8 gpm average point to point. Ready to start taking data on the air filter scoop. I hope you had as good a Father's Day as I have had. Jack B.

I have no tach or any instruments yet. I'll be using my G-295 for everything else on a Ram Mount when I need to get somewhere. ================================================= ---- Eugene Zimmerman wrote: ============ 2 gal per hr. @ 35 / 45 cruise, 55 mph vne. -- kugelair.com ________________________________ Message 8 _____________________________________ Time: 06:33:20 PM PST US From: "Denny Rowe" Subject: Re: Kolb-List: Cayuna 430 and Pterodactyl > Can anyone give me the estimated or actual fuel burn with a Cuyuna 430, > and the usual cruise speed for a Pterodactyl the one with the canard in > front of it. > > Same thing with a Rotax 440 and Eipper MX the single surface old vintage > type? > > Thanks Ron, The Dac Ascender with the 430 Cuyuna burns 2 to 2.5 gph max, likes to cruise from 40 to 50 mph. I sold my old Pterodactyl to a friend that still flies it with a J-bird supplied 440 Kawasaki and belt drive, he burns about 1.5 gph at 55mph+ but he clipped three feet off each wing. The MX will burn quite a bit more and go a lot slower.

Jack, Is that 26.8 gallon per minute, or gallon per mile? ________________________________ Message 10 ____________________________________ Time: 07:51:42 PM PST US From: "Ron @ KFHU" Subject: Re: Kolb-List: Cayuna 430 and Pterodactyl thanks The one I have is basically a loaner. It was in pieces in a shop got it assembled and the Cuyuna fired up after some tugging on the cord. It must have been inop for about 5 years or more. Yesterday I test flew a Rotax 440 on an Eipper MX. What a racket it makes. I can fly on the Cuyuna at low power without ear plugs, not so with the Rotax. That alone is enough for me to favor the Cuyuna motor. Any other advice for flying the duck? ================================================= ---- Denny Rowe wrote: ============ > Can anyone give me the estimated or actual fuel burn with a Cuyuna 430, > and the usual cruise speed for a Pterodactyl the one with the canard in > front of it. > > Same thing with a Rotax 440 and Eipper MX the single surface old vintage > type? > > Thanks Ron, The Dac Ascender with the 430 Cuyuna burns 2 to 2.5 gph max, likes to cruise from 40 to 50 mph.

Dacs are very pitch sensitive so don,t ham fist the stick, if you have the nose down, get off the power or you will overspeed it in a hurry! Like someone else said, the VNE is 55, you will get there in a hurry with the nose down so beware. PRACTICE IN NO CROSS WINDS they don't like cross winds.

Just for fun, even though I have no inclination to do so, is there anyone on this board that has run less oil than 50:1, ( I once saw a company claim you could run their oil at 150:1) If so would you share your results with me? -------- Dale Whelan 503 powered Firestar II I had a Phantom with a Kawasaki 440....got some "advice" from J-Bird......He claimed it needed to be mixed at 20:1 or it will burn up. So I did. In 30 hours the rings had so much carbon packed in them it pushed them out into the ports,,,not a good thing.Landed (glided)on the airfield,took it apart and was surprised at what was in there.Carbon in the ports,exhaust,etc.I also found my gauges were not very accurate..replaced them. Got another used engine with 100+ hours on it,mixed 50:1,,,,,Havoline or Penzoil,,,,and put 260 hours on that one and then sold the plane.No problems with fouling,ring sticking,etc.and never de-carboned it.Ran the same from the day I installed it,to when I last flew it. My friend flew his SE-5A with a Cuyuna for over 300 hours,50:1,Amsoil 2 stroke.Replaced it with something else when it just quit running.Think it was a gearbox problem.
