There may be some, but I hope you never try any stalls or spins in one. I went for a check ride in one, and when I found out the instructor was afraid to stall the airplane, I terminated my Tomahawk relationship. The accident reports for KRs have many,many stall/spin endings to the engine out power failure /fuel failure scenario. Every pilot ought to go through spin training. Once you're onto it, you'll know it's something you want to avoid with out a lot of air under you. Some of the response needs to be learned so that you don't clutch up and jerk that stick bad when something unexpected happens. Filters... A few years ago, I was the tech inspector for an aerobatics contest. I pretty much insisted on good fuel filtration. One (un-nabed) pilot did not have a filter, and adamantly refused to discuss it... said he'd flown in from a long distance and was trouble free. When he started his sequence, he had a total loss of power due to fuel starvation. Lucky for him, the contest was over the airport, not out in some practice zone. Most small aircraft don't land well in rough terrain; big aircraft don't either. Visit the Ellison web site for lots of good info on fuel systems, Ellison and others. Use a filter in your tank to keep birds and beer cans out of your pipes, and then use a good inline filter between the gascolator and the carburetor.

Ellisons are extremely picky carburetors, good but picky. Also it was decided that a fram type plastic fuel filter installed inside the cockpit was a better option. This way they could monitor the contamination the first 100 hours just by taking a glance at the filter during preflight. Something that could not be done if the filter was inside the cowling. I think this filter thing will vary from application to application. Personally I installed one just inside next to the fuel shutoff valve and one inline just before the fuel transfer pump. I want to see the junk before it gets to the carb. Also after reading up a bit on gascolators I have decided I might do without one anyway. Sure its a filter and sure its a water trap but all my tanks have low point drains as well as filters. I get the feeling that a gascolator is something carried over from the prehistoric days. Seems to me its just another place to spring a leak or cause vapor lock. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Sanding and Filling AGAIN! :o( http://www.fortunecity.com/marina/anchor/270/ mirror @ http://www.geocities.com/CapeCanaveral/Hangar/4136/ http://members.home.com/mikemims/ Aliso Viejo CA ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: revflow From: Mike Mims Date: Wed, 26 Jan 2000 19:09:16 -0800 X-Message-Number: 14 KR2616TJ@aol.com wrote: > > > If I'm not mistaken is either a 32mm or 34mm.

The magnetic engine heater should have little effect on your avionics as it will be quite a ways from them. Your electric system will affect on the compass and avionics more.
