  1. I have built a 750. Imported the kit direct from the factory. No problems dealing with them and the support is great. They have a forum with builder resources and back up from the engineers if needed. I can not recommend them enough. There are a LOT of these flying in the US. Spares are delivered within a week or so. The cost of the kit landed here was about 30k. Any more info,I am happy to let you know. Just message me. PS. this was about 5 years ago. Flying for 2 years now. Cheers
  2. Hi Hank. Wade cams are no longer in business but their main man left and formed Clive Cams If you contact Clive on 03 97585977 and ask for the 240 Wade grind for EA81 he will be able to help you. I see you are from Alabama so you would need the Australian prefix before the phone number if you are going to call. I deal with Clive and find him helpful. Message me if you want to know more. Cheers Will
  3. Hi All, I have an EA81 in my Zenith 750. I have completed the first flight and am now doing the 25 hour test flight stage before gaining full registration. My engine is the fuel injected,turbo version without the turbo. It has an SDS computer to control the fuel injectors and ignition timing. The system uses a crankshaft trigger to control the spark and has a coil pack with 4 separate coil leads and hence has no distributor as such. The engine has the custom Wade camshaft and has custom forged pistons and steel con rods which is probably overkill but thats OK with me,better to be over
  4. Hi Ray. Just got a phone call from Phill at Argo. He is trying to contact you but your email isn't working. If you are wanting to talk to him, you had better resend or give him a call. Cheers Will
  5. Ray, The rods were standard length. I doubt that making a long rod type engine would be much advantage because of the short stoke of this engine. The ring pack is quite compact as it is and if you want to use available pistons, it would not be a economical option. If you are serious about using this engine, there is a heap of information on the net. I have mine running now and am in the ground testing stage. So far it looks good. I am happy to share any info. Cheers Will
  6. Hi there Ray. The rods were custom made by Phill at ARGO engineering in Morphet. They were the first of these rods to be made for on EA81 as I recall(the standard ones would probably be more that strong enough) but I wanted peace of mind. PM me if you want more details. Cheers Will
  7. I am fitting an EA81 to my project. The research I did last year showed that the only option you have (in Australia anyway) is the Foxcon redrive for the Terrier. Looks like a good unit with a wide belt but hard to tell if it has a lower support bearing or not. Probably best to get on their website or give them a call. Hope this helps.
  8. Hi there. Just my 2 cents. If you have a carb system, like the Jab, there is no return line. You only need a return line in a fuel injected system because it operates differently and at a higher pressure. The typical carb type set up only uses about 3 to 5 pounds of fuel pressure to the carb or carbs. The fuel is only used as the engine runs through its rev range. At low revs it doesn't need as much as at higher revs/power settings it uses more fuel. Try to think of the carb float bowl like the toilet cistern at home (it is the same principle). When the cistern is full, no water
  9. Hi. Ian, What you are describing is typical detonation damage. I see it a lot on high performance turbo engine where the boost has been screwed up to gain more horsepower without any other mods being done. The ring lands shatter from the detonation pulse, so I would be looking at the fuel you are using and in my opinion, if you are unable to get AVGAS , I would be adding an octane booster or changing the timing setting to decrease the ammount of ignition advance. The scuffing on your piston, if it runs in 2 lines down the edges of the piston near the gudgeon pin bosses, indicates a pisto
  10. The strip is council owned so no problems landing there. The aero club is unmanned most of the time so I don't know how you will go there. Other than that, the rain does make the strip soggy(it's in the middle of cane country) and watch for the bump about half way up the strip opposite the fuel bowser :big_grin:

  12. i will try to post the video of the flight as well as the info from Alans site.
  13. Alan from Zenair Australia has just flown the factory CH750. It weighs 354kg according to his information,so it would be able to be registered at 544kg I would assume. It has a Rotax 912 and wooden prop.
  14. Thanks for all the replys. Really makes it worthwhile to visit this forum. Now I have lots of time to follow up on all your suggestions via the various manufacturers websites etc. Keep the suggestions comming also about the importance of the antenne wiring etc. Cheers
  15. Does anyone have a preferance for Microair as compared to I-Com for coms in their aircraft.I have to choose in the near future and have used both but would like to hear others likes/dislikes problems or otherwise of these radios so I can make a more informed decision. I will probably fit a transponder also of the same make.Thanks
