  1. The ACS switch comes with instructions for starting with only one active mag, which is the usual configuration on lycoming engines.If I remenber correctly there is a link wire to connect to another terminal - so it earths out the unwanted mag when the key is turned to "start"

    Terrific Jetboy, that is what I wanted to hear.

     

     

  2. That's a super cool fan Nuzza!Just a word of caution though, the blades appear to have a lot of pitch. An acquaintance of mine in Darwin thought he'd make a ceiling fan blow more air so he twisted the metal fan blades to give them more pitch. It resulted in the fan running slower than it should and as a result it overheated and caused an electrical fire ...

     

    I'm not an electrician but it has something to do with the AC frequency and the number of 'poles' of the motor determining the speed of the fan. I think ceiling fans should run at 1440rpm on the fast setting with no load so with the blades on providing a load and a bit of 'phase slip' it should be around 1400rpm I think. Much slower than that and the heat builds up. As I said I'm not an electrician and have probably used the wrong terms but it might be wise to check, it'd be a mongrel to burn your plane down.

     

    Also - on second look, did you intend for the fan to blow air upwards rather than downwards? Or is that the winter setting?

    It's really only for looks, although it does run and the blade pitch can not be reversed so yes it is on winter setting.

  3. Hi JustnuzzaA Lithium iron can't be too light for any aircraft, if it affects the W & B then put something else there ie tools, tie downs etc I am replacing my lead acid battery with a lithium iron one and will save 5 kg weight, nearly 2% of the aircraft weight for no downside. This is free extra performance. Most people don't understand the term ultralight aircraft. who was it said "design a plane then add some lightness"

    Cheers

    Weight and balance becomes a problem in my aircaft for rear COG and endurance. I recently had a prop changed from 12 kg to 7kg and I am reasonably light as a pilot. It affects the minimum amount of fuel I need to leave in the aircaft. The C.G point in my aircraft there is no where forward that you can put weight except for the engine bay.

     

     

  4. No replies. Someone recommended a Fullriver battery to me for engine starting but with the colder weather now here I'm finding it difficult to start, works fine in the warmer months. Further research suggests i am in need of something with a minimum of 200 CCA to turn the engine over fast enough. The fullriver is 20AH and 165 CCA. looking at an alternative YUASA or similar any ideas ?
