    Soft start unit for Rotax 912ULS

    Hi, I have this engine in my autogyro. This engine kicks a lot at startup. I have seen on R.O.A.N. that there now is a soft start unit that Bullyhawk is making. Cost is $220. Have anyone out there experience of it? Here in Sweden i have been warned for it. They say it's not good. The idea is...

    Problem with XCOM radio in autogyro MTO Sport

    I just talked to a radio specialist. He think the problem is encoder. This case is ground for the antenna and is situated at the tip of the antenna. He think that is what makes the funny SWR reading. It should not be any ground near the antenna rod he says. I will now move the encoder and...

    Problem with XCOM radio in autogyro MTO Sport

    If you have SWR of 1.2 at 129, can it be a contact problem? I don't think so. Antenna is mounted with 3 screws, under each screwhead there is a washer with teeth that grip the metal good. I also checked when I mounted, that contact to frame was good. I have made the cable. My guess is that the...

    Problem with XCOM radio in autogyro MTO Sport

    As I understand, Rami AV-529 is a very good antenna. I would say it's impossible "it's cut too short". I haven't cut it. It's a standard factory made antenna. Could it not be the groundplane that makes the SWR figures looks like they do? I don't know how to make another kind of groundplane in...

    Problem with XCOM radio in autogyro MTO Sport

    Another thing I have noticed is that the tip of the antenna is very near the encoder for the transponder. When I'm starting the engine on choke, the vibrations make the antenna vibrate against the encoder. Could the metal box about 2 cm from the tip of the antenna have bad effect on the antenna?

    Problem with XCOM radio in autogyro MTO Sport

    I am using RG58. Cable lenght is about 1m. How can I "adjust" the low side below 2.0? radio antenna is more than 1m from transponder antenna, transponder is not on.

    Problem with XCOM radio in autogyro MTO Sport

    I am not 100% sure but I think people have problem to hear me when I'm sending, when I'm flying When I wrote that I have riveted the L-profile to the main frame, main frame of stainless steel is the ground plane. I have measured that the antenna's base is well grounded to the l-profile of...

    Problem with XCOM radio in autogyro MTO Sport

    Hi all, I have mounted an XCOM 760 radio but I have problem, I can't hear what other flyers say. I don't know if the problem is noice or what. When I stand on the ground and even have the motor running, no problem. I have a Rami AV529, rod antenna. I have monted it on a L-profile and riveted to...
