  1. my guess would be, try to type on a small key pad while in turbulence. some times it is hard just to hit the flip flop button on the radio and that is in a canard and they penetrate turbulence way better the most small planes
  2. looks great. like the long nose and it looks like the wings are near done too?
  3. If they do certify it it will be more then a continental 550 . so why would any one buy it. and even if it is certified what does that mean to the homebuilder with a cozy looking for behind the firewall design that he can trust to put in for the family. there is no doubt that a rotary engine will run. it is, will the support systems keep it running? electronic systems used to support the engine are the biggest challenge. there is not yet one system that is proven to be even 90% reliable. the engine has very few moving parts. the gear box very few parts, the mechanical fuel systems are very good. the electronics system have thousands of parts, not to mention all the little electronic and computer bits floating around in there and all it takes is one to be out of place and it will ruin your whole day.
  4. so what RPM do you run to get 210 kts with a 66 x80 pitch prop? what airframe? how many flight hours on the engine?
  5. You second what? her point is that someone still needs to build and prove that they can be a reliable engine system. If you have chosen it because of its know reliability, I believe you will have to build one and prove that to the rest of us.
  6. I would love to see that happen, I would love for it to be me but not in an ez. there was a day when I would have done that but after flying an ez now for many years I have come to realize that it is not the airframe to experiment with an engine. the off field landing success rate is not good. we see aircraft accident reports almost every day about aircraft that have come down out of the sky without power and many are aircraft engines. it is not usually the engine but the support system that fails. so to really test your new relatively stock rotary engine safely you would need a different airframe. so that is simple, just build a slow flying pusher with off field landing capabilities in which to test your new engine, test the engine and then install it along with all the exact same support systems in your newly completed beautiful cozy IV. so lets recap, to get a good reliable rotary engine in a Cozy all we need to do is build another plane, build a test engine, test it for many hours, install the exact same engine in the cozy, test it for many hours and then go flying with your family in your still and always to be experimental airplane with its experimental engine system. so it is easy to see why after someone spends a small fortune and half their adult life on an aircraft that they have dreamed of flying some day does not go with the rotary engine. even many of the few that did dream of the rotary and some of the ones that did install a rotary made a decision if they are going to fly their new Cozy in good health that they best put in a more proven reliable engine system. I applaud the ones that will install a rotary system, the ones that fly one and even the ones that have had their own reality check and choose to make theirs a hanger queen.
  7. even if you did, you have to use it with a heavy C/S prop to get any take off performance. the rotaries don't have the low RPM hp of the aircraft engines. if fixed pitch is used on the rotaries they have to use a lesser pitch prop to get the same take off RPM and that limits the top speed.
  8. I installed a IO-580E on a Glasair III and with the light weight starter and mags removed for electronic ignition it was 390 lbs. and 300 hp
  9. If you can't find it locally it can be ordered from McMaster.com in 6' lengths
  10. the wings are the same out board of the strakes. the rod was uped to 7/16" because many long ez builders had trouble getting the ailerons to balance. Nat used that idea when he did the plans for the mark IV
  11. on some yes, the lightspeed bracket comes with centering tabs on the bracket that touch the crank shaft. after the holes are drilled the tabs are broken off and the bracket is bolted on. very easy to do. the cast aluminum case is very soft and easy to drill and tap.
  12. they are like night and day in the flying department. the Q-200 is very pitch sensitive and rolls about like a 747. very slow roll rate for a small plane. the long ez flies and feels like a small fighter but is easy to handle for the average pilot. the Q -200 is a hand full on landing the long ez is well ez to land. one is like a low powered toy and the other is better then a real airplane
  13. it is straight forward just follow his instructions to the letter. every one I know that did something a better way then he tells you has been bittin in the butt. hopefully you have the crank sensor model. I had the hall effect modules and had many many problems. can't recommend it at all. after many problems in 300 hours I switched to the crank sensor and not one problem in 150 hours. I figure, why put an after market part inside your engine if you don't have to. If it fails it will ruin your engine and the whole day. If you are using the hall effect module check it every 50 hours as he says to. keep an eye on those bearings as they have been known to come loose in the housing. they need to be checked while it is hot. when cold they will feel good but when hot they can be loose. Good luck on the install
  14. you can use any type steel for the weights they are not structural I used stainless steel . that way there is no corrosion between the steel and the glass. Ihave seen older long ezs that have a lot of rust spots coming through the glass on the weigths I have also seen 3/8" brass rod used it is heavier the steel. on the expensive Lancairs they use tungsten rods.
  15. he does, it is because either he knows more about this then any other engineer or he thinks he knows more about this then any other engineer.
  16. the key word here is claimed. thats not the same a tested and proven. to do that they would have to actually build and fly a real aircraft. the aircraft might hit the VNE of 460 MPH but I doubt that the wings will still be attached to the fuselage. but I think that the stick grip will hold up to the pilot inputs, as it will be mostly just squeezing above 300 mph.
  17. Don't believe it is. the white backing on the after market one is acrylic and it does hold up for awhile but starts to crack. does not hold up to alcohol in fuel. the clear front of the gauges is clear PVC. PVC can stand up to fuel and oil even alcohol.
  18. Ya, when I plan a non stop 5 hour flight ( which I never do ) I need to plan for the 2 hr reserve. meaning I may have to stop two hours earlier than planned. even on 3 hour flights I have had to use the two hour reserve.
  19. I agree with Steve, don't worry Steve he is just having one of those designer moments, what the hell was I thinking. 5 hours at 11 GPH is 55 gallons. 5 hours at 200 MPH is 1000 Miles. how much does it have without the implants? have you used up all the space out board? what about making a extension to the tank that protrudes out board into the wing but one that you don't have to let people see. when you fly you don't want to cause the same chaos as a japanese movie monster. at high speeds the extra vortex from the implants my cause cars to overturn and roofs to be blown off. the FAA will have to restrict you to only flying over Groom lake. so as not to scare people or mislead them into thinking that you are advertising for a Madonna concert. what about pods under the wing, that way people will only think you are carrying bombs to drop on the Japanese movie monster and they will be happy to see you fly by.
  20. It is best to make a templet off the plane as there are slight variations in each plane. as tight as the vari panel is, a 1/4" can make all the difference.
  21. I have heard this too. the deeper oil pan on the straight valve may have something to do with it. I do know if you have the cam spray nozzles installed it will heat the oil up more. so another dead skytec starter. was it new. seems one out of two new skytecs are defective right out of the box. if you get a good one they are great but I have seen many bad ones. even had a new one the was not machined right and there was no backlass between the gears and it only lasted three starts.
  22. thats the same thing my flight instructor said during unusual attitude training. well not really those exact words.
  23. Chrissi, step away from the keyboard. now pick up that sandpaper over there, now put it on top of the rough white stuff. now do you remember what to do? it just like having, or riding a bike. do we need to come over there and glue some sandpaper to the bottom of your keyboard?
  24. I did not realize we had no real sense of experimention or vision. so the sweat while test flying is just because the heater was left on. now I understand why all the home built accidents I read about every day, those must be the guys from the other forums doing the real extensive mods.planning mods is easy. building the mods is a bit more difficult. testing to many mods will turn you into a Curmudgeon for sure
