If (one day when it's finished) I am sitting in the cockpit looking forward with my warp drive prop attached to my Rotax 912S, which way will the prop rotate? Or, what 'hand' of warp drive prop do I need for a Rotax 912S?

This brought me to wondering how I can reduce longterm demands on > current supply. Here are some ideas: 1) Spend more time listening than transmitting. With a duty cycle of 25%, you need only one quarter of the alternator supply. During listening it can charge the battery, and during transmissions the battery can supply part of the power. 2) Go QRP. Or at least, use only half te power. 3dB less signal is barely noticable on the other end, but cuts the power demands in half. It has the advantages of causing less RF-related troubles in the ship as well. 3) Use SSB with not too much compression. > I added an SD20S but a 100watt HF transceiver can eat > 20amps easily, I know (car history). Yes, on constant carrier. But why would you want to do that? With SSB with a reasonable compression power demand would go down to 5 amps average, with 3db reduction it is already down to 2.5 amps, and with a duty cycle of 25%, your average power demand would actually be less than 1 amp. So what is your problem? > This led to the idea that the master contactor wants an amp or so all its Well, electronic shops sell relais (mainly targeted to the car industry) capable of handling 40 amps, and using less than 200mA or so for the coil. > My question is: > Have I done a useful thing?

Well, to be honest, I don't find it useful (otherwise I would have done something similar ;-) ). I too have a SD20S, but a split main battery so I have fully separate electrical systems, and switch them with high quality "car-type" relais (with good paperwork) to keep the unswitched leads as short as possible for highest safety and have the power switches at a logical and convenient location at the same time. And in the very unlikely case that a relais would fail, I would always have another independent bus going. I would without hesistation connect my Icom-706 to this electrical system, without any other changes than bonding all electrical parts of the airplane together and installing bridges over all hinges and bearings to minimise receiver noise (which is most likely going to be your biggest challenge). I also suspect that you are going to need to do "something" to the ignition system of the Rotax which is probably designed for max performance and reliability, and not for best RFI-suppression on the HF-bands.

I noticed recently that when its on (continuous ) it strobes, quite fast but it isn't constantly on. Must be the switching that causes the interference.

I did it on my own in about 2 hours. It was a very good test for me to see if all the access hatches and panels were are the right places and BIG enough. A small lockable vice grip to hold the nuts was all what was required as a "special tool". No need to even open up the baggage bay panel. DO IT. It is a measure of safety - the replacement mass balance is much more sturdy - we can save weight somewhere else - not al essential primary flight control linkages.

If you built the mass balance arm properly and didn't bugger up the holes o r have a tail wheel type=2C the original mass balance arm seems to be holdi ng up. But over time=2C side play will wallow out the 3/16 holes and that is what we were concerned about. I hope you have a good sized access hole. If you do=2C it takes 2-4 hours depending on turnbuckles=2C cables=2C your tower width=2C etc. Pretty muc h a no brainer. The new part is properly made and will serve many years without fail. If y ou install the TP18 butterfly attachment for the cables it takes 4 hours. So cut the old cables=2C pull out the arm with weights. Assemble the new a rm on the bench. Rig up a small turnbuckle from A/C Spruce and throw the t hing in. As for the phenolic parts=2C I use #8 screws as they countersink easier. I use a dab of double back sticky tape to set the rub strip where I want it then add just a dab of slow setting thick superglue=2C check it a gain and hit it with the accellerator. I have an angle drill that makes th e premade holes I make easy to do by feel. Insert the nuts and screws=2C a nd pull down. I have some one handed gimicks I use like a cut off stubby s crewdriver that wedges into the post slot and holds the screw. Then I put on the nut and crank her down. Call me when you need one.
