Hello All,I would like to keep going forward with this electronic ignition/batt system idea. Buying a larger amp/hour batttery to extend the flying time to two hours would work, but then I am still left with a dead battery at the end of the flight which would I'm sure become a real pain quickly. So maybe I will keep my 4.4 lb. battery and use the extra weight allowance by installing some mini alternator? I found one in the Pegasus Auto Racing catalog (6 lbs) that puts out a whole 50 amps for $279.00. A bit pricey I thought but maybe I could bite the bullet. I know Ken Perkins installed a (I think it was a Kabota) small alternator on his Model A. Does anyone know more about this? I looked at my engine briefly last night and it looks like installation of such a thing would not be so hard. Just mount to the side, and in-line with the water pump drive belt. How much power do these types of set-ups rob from the engine?Any help or opinionated feedback would be appreciated.

Since I'm on a self-imposed moratorium (for 18 more days) on noting thedangers of using a Corvair to power an airplane, I've enjoyed the discussionabout rudder bar materials. However, I want to point out that we aregetting dangerously close to being as unfriendly, unhelpful and downrightmean as the RV-10 List has gotten.I think a lot of us (myself included) felt that Michael Perez had asked whatmaterials people had used on their rudder bars, and then, when reasons wereadvanced why stainless steel should NOT be used, he announced that he woulduse it anyway. This was often the behavior of The Fisherman, of years past,who would propose to do something and ask if there was a problem. Severalpeople would go to the trouble of explaning exactly why this might be aproblem, and then he would announce that he would proceed with his wayanyhow. He was not looking for advice, but for validation for his choice.However, this was NOT the situation on the rudder bar discussion. In thissituation, Ken Heide initially asked about using cold rolled tubing (?) forthe rudder bar instead of "structural tubing". Mr. Perez indicated that hehad used .035" wall stainless steel for his ALREADY CONSTRUCTED rudder bar.He was neither asking for advice or validation. As he said repeatedly, inseveral emails, " I feel comfortable with my rudder bar set up."I think we owe Michael an apology. It is absolutely his choice whatmaterials to use. It is our choice whether we would fly in such an airplaneor not. That's the beauty of Experimental Aviation. I suspect that afterall the hoopla over his choice of materials, Michael will make it a point onhis preflight inspections to check the rudder bar for cracking. Stainlesssteel is not so bad a material that it will fail catastrophically withoutyielding and with no warning.The great thing about this List (and I really feel that the Pietenpol Listis unique in this) is that people feel welcome to ask questions and offeradvice. There is no "credentialing" to determine who is able to offeradvice, so it takes a while to figure out who knows what they're talkingabout and who doesn't. I don't think any of us want to see this list get sovitriolic that people are afraid to ask questions or offer advice for fearof being publicly ridiculed.Remember, "We're all Snowflakes".

The Latest Buzz on Rudder Bar MaterialJack Phillips, amen and AMEN to your 9:59 AM post. I have never seen, much less flown, an airplane with a rudder bar. All my time (68 years this past January) has been in planes with rudder pedals and toe brakes. So I couldn't comment on rudder bars if I wanted to. Some of the comments did get a bit testy. ----- Original Message -----

Jack I agree whole heartedly. Dan Yokum and Gary Boothe will attest to the waymy attitude has gotten. There have been a couple of topics that I have felt qualifiedto offer up advice on but didn't because of fanning the flames. I considerus to be a fraternity of builders that very few builders get to experience.I have been wanting to build a Piet over 40 years and this glorious Internetcame along and we can share pictures and ideas freely. While I don't agree withsome posts I try not to flame the poster. I may ignore it! While my rear rudderpedals are 4130 my front pedals are stainless tubing but I would fly onewith the pedals made from 1/2" EMT conduit. My opinions:Welding 4130...... Tig or Oxy-Acet makes very little difference. Quality of theweld is what matters. I have both and used both on my airplane. Close placesI prefer the torch over TIG. I have not made the engine mount yet but I wouldguess it will have both. Any TIG welds on it will be stress relieved.Finish....... with today's fabric dope, auto paint, latex house house paint, oilbased house paint.......all will work. My Piet will have Rustoleum oil baseon it. The 1/4 scale Fleet in my avatar is 11 years old, is covered with Dacron,has sat in the sun several days in that time span and has over 100 hours inthe air. I am comfortable using the Rustoleum because of its performance on thatmodel. It still looks nearly new.Engine selection.......I won't get too deep into it. Auto conversions are OK ifdone right. I like the reduction drives to get prop efficiency and take the gyroscopicforces off the crank. I prefer certificated engines because they needno conversion, most have no head gasket to blow, have individual stand alonecylinders so you can repair just the one that gives you problems. I also likewooden props over metal as they are kind to your engine and look good to boot. Welding and engines are my life's work. Certified gas pipeline welder at 18 yearsof age then did maintenance on stationary engines of 2000 to 15000 horsepowerfor 41 years. I worked part time in a FAA approved repair station 4 yearsto help support my flying habit. I did engine work for them and helped with someannual inspections. Does this experience make me a welding and mechanical guru?No. Not by any means but I have seen the innards of a lot of engines. Anyonewanting personal opinions one on one feel welcome to email me or call. Thepictures show the big ones break just like a small one. I bent the rod in 1975starting the engine. It had water on in the cylinder(now we know why you pullinverted and radials through before starting). It has 12" journals on the crankshaft.That rod cost $18000. The other one with the broken piston skirt wasbecause management chose to buy aftermarket(cheap)cylinder liners and it failed.That engine has a 16" bore and 22" stroke I get off the box now. I hope I have not offended anyone. It was not my intent.I am trying to promote harmony.

Does this experience make me a welding and mechanical guru?No. Not by any means but I have seen the innards of a lot of engines. Anyonewanting personal opinions one on one feel welcome to email me or call. Thepictures show the big ones break just like a small one. I bent the rod in 1975starting the engine. It had water on in the cylinder(now we know why you pullinverted and radials through before starting). It has 12" journals on the crankshaft.That rod cost $18000. The other one with the broken piston skirt wasbecause management chose to buy aftermarket(cheap)cylinder liners and it failed.That engine has a 16" bore and 22" stroke I get off the box now. I hope I have not offended anyone. It was not my intent.I am trying to promote harmony. We have a good bunch here and let us have fun.--------Jerry Dotson59 Daniel Johnson RdBaker, FL 32531Started building NX510JD July, 2009wing, tailfeathers done, fuselage rollingusing Lycoming O-235Read this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/bent ... ______Date: Thu, 3 Mar 2011 22:15:29 -0600Subject: Re: FW: Pietenpol-List: Gene Pennington

Hello All=2CI would like to keep going forward with this electronic ignition/batt system idea. Buying a larger amp/hour batttery to extend the flying time to two hours would work=2C but then I am still left with a dead battery at the end of the flight which would I'm sure become a real pain quickly. So maybe I will keep my 4.4 lb. battery and use the extra weight allowance by installing some mini alternator? I found one in the Pegasus Auto Racing catalog (6 lbs) that puts out a whole 50 amps for $279.00. A bit pricey I thought but maybe I could bite the bullet. I know Ken Perkins installed a (I think it was a Kabota) small alternator on his Model A. Does anyone know more about this? I looked at my engine briefly last night and it looks like installation of such a thing would not be so hard. Just mount to the side=2C and in-line with the water pump drive belt. How much power do these types of set-ups rob from the engine?Any help or opinionated feedback would be appreciated.
