    How do I know if a Transponder is compatible with ADS-B

    I don't even know if that is the right way to ask this question or not but here is what I am looking to do. I have two airplanes and neither have transponders. First plane is an Aventura 2 Amphib. This obviously isn't a cross country machine and I don't fly into any airspace where a...

    Can I paint a composite plaine a silver / grey color?

    I recently purchased a flying quickie Q200 from a local pilot/builder/owner. It needs a fresh coat of paint and originally I was thinking stick with the white but my paint guy (who is also a pilot) said that silver / grey would be comparable to white as far as reflecting light / heat. We all...

    Static Testing a Wing

    I am looking for some information on the procedure to perform static testing on a wing. The intent is to flip the wing upside down and use a test rig to attach the struts (flying wires actually), then load it up with sandbags. The questions as of now are: Do we need to put it at a high angle of...

It has a mechanical fuel pump on the accessory case and the electric fuel pump next to the tank. I take off with the electric on and then shut it off once...

    using induced draft airboat style cowl rather than ram air

    The subject here is in regards to using an airboat style cowling for slow pusher amphibian. See pic. Do you have much or any seaplane experience? I'll proceed as though you don't but you'll know all of this if you do. What concerns me is the downwind taxi scenario where step taxi is not an...

    fresh overhaul run up - pusher

    I'm getting pretty close to being able to fire up the 0-235 I have been building. Reading the ground run in procedure they spend a lot of time discussing how to cowl an engine for the run in period and of course none of this applies if you're in a pusher configuration. Test stand isn't really an...

    Is there some kind of reference book for aN hardware and fititngs?

    The amount of specialized AN hardware and fittings never ceases to blow my mind and excite me but I find it is very hard to locate some if this stuff. Is there some kind of a reference book for this or do you just flip through you aircraft spruce catalog to find what you are looking for?

    O-235 removing oil cooler - plug taps or installl line?

    I am installing an O-235 in my airplane. The engine is a C1B but I got my hands on an L2C Accessory case as it was setup with the mechanical fuel pump and oil filter setup I need / want. From what I have read there are plenty of o-235 installations that do not use oil coolers and I do not...

    Thrust Angle for Pylon mounted pusher

    I am redesigning the engine mount on my Aventura and while I am doing so I want to adjust the thrust angle from where it was (0° with respect to the chord line) to reduce the downward pitching moment when thrust is added (or more importantly the upward pitch moment when thrust is reduced) and...

    Wiring retard breaker ignition to allow starter to engage without sparking mag

    Helping a friend out. I get a little confused looking at the wiring diagrams for retard breaker mags. It seems fairly straight forward to wire up if you use a L-R-BOTH-START key switch but we want to be able to crank the engine without starting it. I guess the question is really when the retard...

    O-200 In pusher (A to B)

    I'm considering an O-200 for my airplane which is a pusher. My understanding is that your standard O-200 in tractor configuration is an O-200A and they did make an O-200B for pusher configurations. is it possible and if so what does it take to convert the A model to a B? Thanks

    Optimum ALuminum alloy for an engine oil pan

    Long and short of the question is high vibration area like this, what would you recommend? Needs to be weldable, bendable, and have good fatigue properties. I had narrowed it to 5052-H32 and 6061 T6. The 5052 is appealing as it will be much easier to bend. I have scoured the net and I haven't...

    Headseat Microphone VOX sensitivity

    I have a flightline 760 radio / intercom. It is a nice little unit and for the money I have been very pleased with it. Unlike most other radios I have used the VOX / squelch sensitivity is a setting you have to go in and change between 4 set points (HI-LO), not a dial. I wear a Bose A20 headset...

    I have a set of blackmax wheels / brakes / axles on the Aventura II I built (this is what is commonly installed on these). The airplane has only about 5 flights on it and no hard landings. I had a total bearing failure on the right main, after /while doing some high speed taxi tests, only to...

    Tail wheel load design consideration

    I have found that my aircraft has an aft CG and I need to get as much weight out of the tail and forward as I can. The only place I can really get weight out of is in the tail wheel. Since this is an amphib it is a unique set up as the tailwheel retracts. I currently have a Matco T-8 wheel which...

    cg range in % MAC

    I don't know why I am having such a hard time with google finding information on this but I'm trying to find some hard fast documentation on safe cg for conventional tail planes expressed in % MAC. Particularly the aft limit. Does anyone know of some information out there?

    options for transceiver antenna with no available groundplane

    I am building an Aventura II. It is very similar to the sea rey if you are familiar with that- Bolted together aluminum tube structure with a fiberglass hull making up the fuselage and fabric wings. So there is no 4' diameter piece of aluminum to use as the ground plane. I have looked at the...
