FWIW, I had an older certified Alcor combination EGT/CHT gauge that used adjustable pots. It eventually started to have intermittent problems on the CHT side. The culprit was the little adjustable po ...

I don't believe I've ever seen a definitive answer to the question of what the exact purpose of the 22,000 mfd capacitor is in the 912 charging circuit. Can anyone answer that question? I apologize ...

Can someone on this list tell me definitively how the Rotax/Ducati regulator/rectifier as used with the 912 series engines actually works? There is so much conflicting info on the internet about it. ...

I'm pretty sure that this has been brought up before, but not sure if any answers were provided. I receive the Daily List Digest via email, and today's digest for 10/04/17 contained 9 messages. Follo ...

Although I haven't actively posted on this forum, I'm a builder of a S7 SS for several years, just getting close to flying. I get the email compilation of daily posts (if any) every day, and always c ...

Need some help from the experts. I have been looking for a DPDT switch off-on-on non progressive. It seems like such an animal does not exist. The switch will be used for wigwag/ landing lights. ...

On another internet forum the question was posed - "Why do you need a capacitor on the Rotax charging system?" A reply was posted by another member:

"In our charging systems, the st ...

I stupidly did a very nice ADS-B UAT antenna installation on my new project before doing all of my homework. It is 45 inches from my transponder antenna. I just received my ADS600-EXP unit. NavWorx s ...

Since there seem to be quite a few Rotax users on this forum, I have another question... is it really necessary to separate the wiring coming from the engine (pressure & temperature sensors, tacho ...

All, The ignition modules and the pickups together cost almost $4,000 to replace. A few feet of shielded wire costs what, $1.49? I'd wire it exactly as Rotax says rather than experiment.

This may be a dumb question, but would using a shielded twisted pair for the combined ignition control wiring to both modules be OK, or are 2 individual shielded single conductor wires preferred for s ...

With a tremendous amount of work by the EAA Mile High Chapter 43 Young Aviators group, and many volunteers, the mock-up of a B-25 cockpit will be at KidVenture/Oshkosh this year. I want to thank Bob N ...

Good news, Bob... the guy putting this together, using your circuit and donated parts, figured out what he had done incorrectly and now it works! I just received word that he is going to deliver th ...
