    That's a nice looking airplane.

    How about a Cessna without rivets or SIDs?

    Skippy: Are those LPM figures for pumping to the same height as the fuel container or above it or below it. If above the fuel container, how much higher? I like the idea of this pump and am wondering if it is suitable to refuel a high wing from a container on the ground.

    My engine also shows a higher pressure when cold than when warm. As I understand it, this is because of a temperature sensitive bypass valve in the oil filter.
  5. cscotthendry
    Yes, it was very easy to tow, and very stable. Also with the long wheelbase it was easy to reverse.

    Here's the drawing I used to guide my trailer maker. The plans are not a cookbook solution and should be tailored to your trike. I've also included a pic of the wing rack setup. The positioning of the racks was done 'on-the'fly' having the trike on the trailer for positioning and setting the positions so that the wing didn't extend beyond the width of the trailer in the back, nor beyond the length of the prop extents. The plug on the back of the trailer with the wire connected to it, powers a second set of tail lights on a board that I hung on the prop for extra safety. Edit: The stone guard on the front of the trailer is a necessity. If you look closely at the pics, you'll notice that the shadecloth screen doesn't go all the way to the bottom of the guard. I used to regularly find little pebbles on the deck of the trailer that no doubt would have hit the trike, without the guard.

    From memory, the decking was around $1800 and that was, what? 10 years ago??
  8. cscotthendry
    Just checked with the cheese n kisses... We think it was in the order of $4,500. Told you it wasn't cheap! :-)
  9. cscotthendry
    It wasn't cheap...that much I remember. I'll see if I can find the receipts.

    That should have said VERY easy to install the wing covers
  11. cscotthendry
    You will easily get 90kt cruise out of the Nynja even with the Dacron wings. The Dacron wing cover are not a drawback. They are VERY to install (and replace when needed) and don't reall create that much more drag than ceconite. Greg Robertson always claimed to get 100kt cruise out of his Nynja, which I used to scoff at, but looking back on it now, it is certainly possible. I used to cruise my Nynja at 5,000 RPM and the rotax will sustain significantly higher than that for long periods. If you build one, ther are any number of people (including myself) to refer to for questions or assistance. I miss my Nynja and would have it back if I could afford two airplanes.

    Skippy: Excuses accepted...busy times. Yes, I notice all kinds of funny sounds (that really aren't there) when over tigers or water.
  13. cscotthendry
    And soooo??? Any update on the tacho?
  14. cscotthendry
    This is the world we live in now, where the $$$ rules everything, and Everything Has to make a profit. Our taxes are not for public infrastructure or services anymore, they are for handing out to business in one form or another.

    The GPS function is contained in the patch antenna and is a standard off-the-shelf unit. The display unit runs on a version of Windows CE (I think) so anything could be happening in its little brain. Mark: The heading freeze only seems to happen on long flights. I think the earliest I've noticed it was around the two hour distance and then, not always so. I've had lots of flights with no problems, and just enough with problems to make the unit untrustworthy. When it starts freezing, I usually turn it off for a few minutes and then back on, but that destroys the continuity of the track recordings which I sometimes use in my videos.
  16. cscotthendry
    Yes, they reply very well, but the things they aske me to do are not practical while flying, such as While flying, if the heading freezes, to disconnect the GPS from the panel dock and plug in the external antenna through the cigarette lighter power adapter. They have also asked me to do other things to try to troubleshoot the GPS which are not practical while flying.

    Very good question Skippy! Especially relevant to tachos specifically marketed for Rotax engines. My only guess would be the Heisenberg uncertainty principle. It is impossible to measure something without affecting it. So my theory is that, tachos are made like multimeters, with the highest input impedance possible, so they present less loading to the signal source, thus not affecting it so much
  18. cscotthendry
    There you go! The resistor is already working... :-)
  19. cscotthendry
    Yes, the actual resistance value is not critical. Most tachos have a high impedance input design. The tacho coil on the rotax engine is an inductive pickup (basically a coil of wire around a metal core) that is triggered by a magnet on the flywheel whizzing past it. This can generate very high voltages when coupled to a high impedance. The high voltages overwhelm the semiconductors in the tacho's input circuit. Putting a resistor in parallel with the tacho input lowers the impedance and drops the volts down to the point where they don't cause "breakover" in the input transistors of the tacho.
  20. cscotthendry
    Connect a 200 ohm resistor across the signal and ground leads at the tacho. Should fix your problem. Also search the forums here for threads on this where it is discussed at length.

    I'll second Skippydiesel's post. I was wondering if someone was going to eventually bring up the grounds issue. Being an auto electrician, don't be tempted to follow auto wiring practice of using the frame as the return electrical path. That is just asking for trouble. Get yourself a big heavy bus bar with lots of screw terminal points, connect a nice heavy cable to it from the battery and connect the ground from EVERY piece of equipment back to that bar. If you do that without exception, you'll likely have a lot fewer electrical issues. Do not be tempted to shortcut this to save a bit of wire or work.

    Jeff: Yes, I do still have the plans, but I'm out of the country at the moment. I'll PM you when I get back.

    XC you never know unless you ask. We personalised our rego to some extent on the Legend when we bought it. I just asked the person who was incharge of issuing the rego numbers and she helped me find a number that means something to us.
  24. cscotthendry
    I would go with converting the trike to RA Aus rather than you converting to HGFA. That way you only have to have one membership fee each year, but as importantly, you have one set of regulations to learn and follow. Yes, it will mean changing the rego numbers which will be a pain, but IMO worthwhile.

    At Dingo, we filled up at the 95RON pump. They didn't have 98, but the Rotax is rated for 95, so all good for us. For most of the rest of the trip we filled up with avgas, so the mogas would have diluted that some.
