Kit Aircraft Modifications

Greetings,

I hope that everyone had a wonderful holiday!

I have an airplane that doesn’t have a small window for the pilot to open and shout “CLEAR” out of when starting the engine. When it is cold out you want that door shut and with its gull wing design you cant leave it raised with the engine running.

Initially, I thought that it would be neat to have a small powered PA speaker mounted in the engine compartment through which you could broadcast your “CLEAR” at the appropriate time. It would be somehow linked into the audio panel and your headset microphone. This idea proved to be more trouble than it solved.

I then got the idea of installing a small car horn in the engine compartment so that you could warn a larger area with the touch of a button while keeping the doors closed.

I wired it such that the horn circuit is energized only when the starter button is energized. This would keep inadvertent activation to a minimum.

I works very well except for the cheapness of the horn I purchased. It doesn’t sound very authoritative. I guess I will have to be on the lookout for a different horn.

Happy Building,

Dave

Hi everyone,

I would like to announce that I have started a separate blog that will talk about my Dail2Start Cellular Control Units and in general remote control via GSM controlled switches.

I would be very pleased if you signed up to follow either of my blogs as this gets the word out further and wider to people who might be interested in purchasing my units.

Briefly, the Dial2Start Cellular Switch can operate any 100v appliance, motor, pump,etc. from anywhere in the world via SMS text messaging. It works great for starting up furnaces at cottages, controlling vehicle pre-heaters and such. Heck, I even have a unit in a bill board controlling a JackPot sign that lights up when the casino has a winner!

I would be pleased if you had a look at the new bolg and sign up if you are interested. It is located at:

Thanks,

Dave
