Re: Prop selection / Sterba props
Peter Harris <peterjfharris@...>
Thanks David. I am looking for the best cruise prop match I can afford for a Q-200 powered by Jabiru 3300. I think maybe 60x72 or 58X72. Still taking advice and waiting to hear from Ed Sterba. Hope you can help?

Re: Q1 mods
davedrosen <d2r@...>
Smooth,
My q1 is getting a 60 Hp, Hexadyne Engine, should see it in two weeks. Putting on a custum made composite Price Aviation Prop, should have it this week. Intrument panel is not attached to the canopy. Has Garmin gps and transponder, with xcom760 radio, and a Taskem monitor (can see pics on Q1 group). Using go kart brakes. Pitch trim will be based upon a spring cylinder used in Cirrus aircraft. Beefed up rudder to fuselage connection. Beefed up firewall to support bigger engine. Hope to fly Next spring to sun n fun or if I don't make it oshcosh in July. That covers most of my mods... oh, access hatch in back to access push tubes, and dual cables so rudder and tail wheel are seperate. If your just starting a kit... to be done by spring is very aggressive. I wish you luck. I think it should be a fun machine. Dave R.

Re: [Q-200_Engine_Group] Fuel injection anyone with carb?
Peter Harris <peterjfharris@...>
Great work Ron. Now that I am starting over with an aircooled engine I have got a lot to learn again. A few years ago when researching air pumps for an exhaust extractor I found a good article by Barnaby Wainfan in Kit planes. Need to flare the end of the exhaust tail pipe inwards to create turbulence which traps surrounding air and carries it out the duct. There are also design details to show how long the tube should be and a double acting extractor as well. If you need it I will look it up.I have a pdf showing details of the Jabiru ram air ducts which are similar to yours. I would be interested to see some performance figures compared to the old fashioned method.

(remember that it still has dual coil packs driving two sets of plugs and I think that there would be an extreamly low probability that both coil packs would fail at the same moment). That is why I felt that a seperate source of spark on one set of plugs did'nt buy me much saftey. Last time I checked you needed fire, fuel, air, and compression to make power. Take any one of them away and you are in just as much trouble as if they all went away. I also considered a secondary spark source on one set of plugs, but with a mag you lose the abaility to advance/retard spark timing. If you are after more power, then the secondary spark source would have to be electronic. So yes, an EFI system failure will probably make the engine stop. And yes, if you lose one mag in a dual mag and carb setup all you have is reduced performance, and if that makes you sleep better, then make that choice. Again, I am not trying to sell a particular setup either way, just add some insight into my choice. I wanted the increased performance and was willing to accept what I determined to be the very small additional EFI "single point" failure risk by using good quality brand new equipment with an installation that has hundreds of flight hours on it. We can all tell stories of old cars that broke down. That's not what I'm putting on my plane. I can also tell stories of carb ice, bad fuel, worn mags, ... Remember, there is no such thing as a fail safe airplane, and we will all live or die with our own choices. For me it's a game of risk management. Hope this helps, Tom in Tucson _____ YAHOO!

Re: [Q-200_Engine_Group] Fuel injection anyone with carb?
Peter Harris <peterjfharris@...>
Ron that sounds like a good design using exhaust pressure to pump cooling air and a real throttle body as backup to fuel injection.I thought I had invented the second item...... dang you will be the first to try it.Have you got pics and details.
toggle quoted messageShow quoted text
Also I am looking at ram air plenum supplied by Jabiru to direct air onto the cyls. Is that your plenum ? Has anyone got performance details for this mod? I was planning to do the conventional and carefully shroud the engine heads to force feed air through the fins. Ram air ducts or a plenum would increase pressure and airspeed through the fins but not necessarily improve heat transfer and cooling?. Peter

Lynn and David, Lynn, I hope you don't mind but I have made my plenums similar to yours in a few ways around the spark plugs and the area they cover. I am going ahead and adding the top and bottom deflectors inside the plenums which will end up out the bottom center with a 4 into 1 exhaust helping to pull the air through. I also am using one mag with one electronic ignition, the Mega Squirt and Mega Jolt which I have built. The pickup for it is already mounted behind my prop hub as shown in the picture. I sure like the idea of having backup for the injection by leaving the carb which I will also work on. I have uploaded the latest photos of the above and can be seen on page 10 link at the bottom of this message. Will add them to the Q engine page photo section also. Let me know if you see anything wrong. I was very impressed with your plenums back at Spring Fling.

David, Prior to this recent discussion on fuel injections I was planning to buy a Klaus or Rose electronic ignition for one set of my plugs. I have now completely changed my focus to a complete Engine Control system with integrated fuel injection and ignition control. For only a couple hundred dollars more I have fuel injection along with the electronic ignition I wanted previously. I have narrowed my search down to 3 brands and have been putting together the components list. The fuel injection side of this looks to be much more straight forward than I would have thought since I am currently planning on only making new intake runners and leaving the carb intact as the backup up fuel source as we spoke. The ignition side will be electronic on one side only for now coming from the ECU. The other side will remain as a mag for redundancy until a good alternative comes along. The mag will be controlled by the P lead as it is now with a second ignition switch controlling the electronic side. I have updated the design of my electrical system to accomadate the need for electrical redundancy. I am currently thinking through the run-up checklist for proper confirmation that all redundant systems are operational. Then it's time to get out the check book. Downfall is that I will be adding a net 4 pounds after removing one mag. Guess I won't worry about what to do this winter - not that that has ever been a problem. Anyway a long ramble on where I'm at on this, but I welcome anyone's feedback. Regarding the mold for the plenums, I guess I had never thought about it. I am very pleased with these and would do it exactly the same way again, except maybe not so many plies so as to make it lighter. They snap on and fit like a glove and yet allows easy access to the plugs. The other thing I might change is maybe improve the transition from the plenums to the cowling. Needs some sort of boot or something that will slid on and off easily with the cowl. Maybe sometime when I have them off I can pop a mold off of them. Did you come out OK with yours? Lynn Lynn, I'm not an electrical guy, but the P-lead would handle the mag side, and I hadn't thought about the wiring the two spark sources together. You're much sharper at this stuff than I. Another topic: Have you ever thought of making molds of your engine plenums? I know after making mine, I would have gladly bought some from a mold. D _____ Cool! I'm liking this idea. What are the con's of doing this? Carb is heavier than throttle body, carb is an expensive throttle body, adapting of TPS to carb. I can handle all of those in exchange for redundancy, what others? Lynn French Lynn, Actually, what I'm saying! But you don't need to shut off the fuel to the carb, just go full lean on the mixture lever. That way if you need to restart you would have the carb bowl full and ready to go. It will work and has been done, I just don't have the energy to do it. ;-) ~D~ _____ David, I think I understand what you are saying......use the carberator as the throttle body for the fuel injected system and just add a Throttle Position Sensor to feed the ECU. Have a seperate fuel shutoff for the carb fuel and if the Electronic system fails just turn on the fuel to the carb. Ignition can be backup up in several ways including one of the mags. Is this what you are saying you have seen? Seems like it would work. Thanks LF Isn't Clause doing that with his Vari EZ, I heard that somewhere and I think it is a good idea also. Probably will do something like that with my Mega Squirt. Ron T I have seen a TPS on a carb using it at a redundant fuel supply or (system). And I don't see why one could drive both plugs with electronic ignition with the mag still in place and activating the mag incase of failure of the ECU.
