    The A model Avid had a welded in place motor mount. That may have been redone when they put the 582 in??? Jim Chuk

    Will a avid a model firewall forward fit on a mark-4
    I'm thinking about buying a A model Avid.
    It supposed to have a Mark-4 upgrade firewall forward 582 engine kit.
    Engine will have to be rebuilt.
    Just want to know if it will bolt onto a Mark-4 with out any modifications.
     
    Also what is a set of full Lotus floats for an Avid worth.
     
    Thx marv

    additional to all this, I know somebody had an annoying sound on the radio and after tons of investments on filters and all sorts of things, he couldn´t get rid of a cracking sound on the radio, he later find out by accident that one loose ground contact somewhere was vibrating against a metal plate and creating the noise, it was worst at high RPM and start or stop ramdomly.
     
    spend money and even worst "LOT OF TIME" and all what he need it to do is just tight a screw......

    The way it reads now is that only necessary crew be allowed in the aircraft during phase one... in the interest of safety, how  am I spose to have my eyes outside the cockpit watching for traffic etc all the while taking detailed notes of various speeds etc... If it was ever questioned I would make the case that the second pilot (or engineer) was along to record data while I performed the sole duty of flying the aircraft and keep myself and the other planes in the area safe from mid air collisions.  I would LOVE for them to try and fault me and tell me that in the interest of safety I could not deem the second crew member as a necessary flight member.... As the Pilot in command it is up to me to determine required flight crew not some bozo on the ground... much like the tower telling you to do something that you cant comply with.. we have the right and the responsibility to tell the tower to politely piss off while we are trying to manage what ever emergency or flight condition we are dealing with at the time.
     
    That being said, it is nice to know that they are trying to officially change it to make it more clear, however, since it is a government agency, I am not holding my breath that the waters will not be any less muddy.

    FAA considering ALLOWING 2nd PILOT for PHASE 1 TESTS
    Article in this months Kitplanes mag concerning the possible rule that a 2nd QUALIFIED PILOT may be allowed to fly in EAB Phase 1 testing for safety reasons - Applies ONLY to KIT-BUILT planes and not to scratch-built.
    Another article shows inside of Rotax Factory and some 912 engine details.
    EDMO
    UPON re-reading the article, I found a small note that AC90-116, allowing a 2nd pilot, had been approved and released 23 Sep 2014, and that the necessary OPLims modification  paperwork is still in review, but expected soon.

    thanks for the ideas everyone, I have no ground wire bonded to the frame just the 7 camlocs that hold it onto the airframe but maybe its not grounding properlty ,worth a try

    I used an inline filter I got from napa aircraft section do you have a ground wire from the turtle deck to the air frame? I has to put one on my brothers kitfox to make the antenna work good with it on the turtle deck.

    If it's an ICOM they sell a DC power supply with it built in. Kind of spendy but works well.

    I had the engine/alternator noise problem in mine. I got a noise suppressor at radio shack and put it in the power line to the radio. Seems to have fixed it.

    If your noise is a whine from the alternator, then a Capacitor, often called a filter, should take care of it - ask someone with more knowledge than me as to the size and location for your system - I think it is on the ground side? Rarely do these go bad, but it has happened, and a replacement fixes it.

    Wished I had some great suggestion, but if not installed, find a recommended inline filter on the DC supply to the radio. Radio user manual might have a recommendation. Also, there might be some filter/suppressor suggested by your engine mfg to instal across the charging system, etc. Noise or other interference can be a pain to get rid of.

    Thanks for posting this, I'm having problems with radio noise,it seems to be worse at high rpms and my antenna is bolted on the turtle deck which is all aluminum ,so Im  thinking the  grounding shouldn't be a problem, is there a noise suppressor I should try or any other ideas , I seperated the antenna wire as far away from the electrical wires a s possible but hasn't fixed the noise,the radio model is a  FL760

    Do do believe the horizontal radials (ground plane) is nearly the same length as the vertical length of the antenna for a given frequency. Actually, about 5% longer than the vertical/radiating element.
     
    That ground plane should also be electrically connected to the shield of the feed line (coax) from the radio and is to be connect at the base of the vertical element. I'm not exactly sure how this works out with some sort of metallized plastic film. The gorund plane is actully the second half of the antenna system. With out a properly connected ground plane, in a sense, you only have 1/2 an antenna, which might not be good for the transmitter in the radio.
     
    I added 4 radial wires under the antenna inside my FP202 Koala when a good friend of mine told me I had "a nice 1/2 an antenna" in it. (old ham radio guy from way back, I mean way back. He just turned 101 2 weeks ago.) I didn't have it when I had my Koala FP202, but It would have been nice to test that home brew antenna with my antenna analyzer. This analyzer checks impedance, resonance frequency, SWR, % of match and a whole lot more.
     
    I was later using a "no ground plane required antenna" in my Koala which I made during a training session with Paul. (That old friend of mine.) With that antenna, I was talking with someone in the pattern at an airport 100nm away. That radio check was done with my old STS handheld radio using it's attached battery, not the12 volt battery in the plane. Not bad, huh?
     
    FYI: Transmission is a totally different animal than receiving. If only receiving others transmissions, that ground plane makes little difference. In transmission, the antenna system is everything. If your SWR, % of match, etc is not at or close to that which it should be, much of that energy your radio is putting out will be radiated back into the radio and can cause damage to the transmitter/outputs of the radio. My friend Paul told me I was lucky I didn't burn out my handhelds transmitter, not having the ground plane radials under that antenna.
     
    Again, I'm not sure how the metalized poly is electrically connected to the antenna/coax. As for reducing engine or IFA prop system interference, I know this. RF interference travels in mostly straight lines. I'm picturing this metalized film ground plane material mentioned by OP or what ever it is, might be large enough and of size adequate to block RF emissions (noise) radiating off the engine ingition, charging system or off the motor(?) of the IFA prop system. Another form of noise a radio might pick up on is noise from wires/electrical system itself. That's often reduced or eliminated with filters and such across wires, components, etc.
     
    Now, perhaps I've confused the topic enough. If I can clarify or answer anything, please ask. D

    I cant fly it. It needs some repairs to be done with it. I brought it home to Ohio from Florida this summer, but i didnt have time or that green stuff to work on it. I plan on working on it this next year if I can.

    It is very hard for a limited production engine to equal the price and proven endurance of a suitable automobile or other land vehicle engine. The hardest part is finding and adapting a suitable one.

    Hello Michael and co;   when are we expecting to see any of your engines on the market and what are the estimated costs??? Looking forward to see more reviews such as reliability fuel consumption, TBO and so on...   looking forward to hear from you soon.   Regards Graeme Williams <grarobwil@bigpond.com> 25/1/12     para mí   Hello Dimitri,
     
    Thank you for your interest.
     
    We had hoped to have our 250cc version available about midyear, but the company we were negotiating with in Germany to manufacture these engines under license has fallen through as of the 23rd January and the release date for this model engine is unknown at this time.
     
    I sorry but that is all the information I can tell you.
     
    Please keep in touch and I will keep you updated on any progress.
     
    Kindest regards

    way too early (ejem...since 2009 nothing has happend) to say anything about the engine really, we are GUESTIMATING the performance, but the paper says that has a gear ration of 2:1 and achieve it´s maximum torque (based on the demonstrator model) at 3500RPM.
     
    this is not a rotary engine,  Junkers was using a diesel engine with a rotary sleeve valve as well... I sent them a mail a couple of years ago, asking more about the engine and I got a very vague answer, don´t know really what are they holding on for...

    the plastic plane guys use a copper or gold tape or film to give them a groundplane for their antennas.
    A thin sheet of aluminum or stainless will do the same - I think it needs to be about 1/4 radius of the length of the antenna, but surely someone on here knows more about that than I know.

    I don't store my avid for the winter, but I use the mercury fogging oil in all my other two strokes.. Fog the boats in the winter and the snow machines in the summer.  I have never had a problem with rust or corrosion build up using it.
