Are any of you using impulse mags? I just have the old bendix's and starting is OK, but.Craig________________________________________________________________________________

Craig,I have used impulse coupled mags for many years because they eliminatethe problem of kickback, particularly when doing a hot start. With a direct drive magneto, you have a 30 degree spark advance whch will al-most guarantee a kickback when using a wooden propeller. If a metalpropeller is used, a strong and skilled "armstrong" will be able touse the greater inertia of the metal prop. to carry the piston overtop center, thus eliminating kickback and a lot of danger.One needs only to have one impulse magneto on the left side of the en-gine (when viewed from the rear). It should fire the lower plugs andthe engine will be started on the left magneto only, switching to "BOTH" once the engine is running. The right magneto can be a directdrive type, firing the top plugs.I consider an impulse magneto to be an important safety feature thatmakes starting much easier. For added safety, I have incorporated apair of toggle type ignition switches on the right side just behindthe firewall where they are handy when swinging the propeller from therear. They are connected in parallel with the switches in the cockpitand will enable you to kill the engine at any time.Hope this helps.Graham On Thu, 27 Feb 1997, Craig R.

Stevee,Do you have bendix mags? The points are expensive. About $70 a set. They seem to work fine though. Everything needs to be just right to get it to start. I guess these engines all have a different personality. The manual with the C-65 I bought is very good. If you need a copy let me know. The condensers are a problem. The new bendix condensers have been on the shelf forever and don't all work like they should. A 9-N Ford tractor condenser also works.Craig________________________________________________________________________________

Graham,Kick backs haven't been a problem, but the C-65 is just hard to start when it's hot. What kind os impulse mags are you using? I got 1/2 hour of flying time in yesterday. I wasn't dressed as warm as I should have been.Craig________________________________________________________________________________

Hi Craig,At least you are doing SOME flying. This has been a long, miserable winterin these parts and I have not flown my Piet since last October. Have myWag-A-Bond (homebuilt version of the Piper Vagabond) on skis but haveflown it very little. Some winters I have flown the Piet every month, butit would not have been feasible this winter!Impulse magnetos do make hot starts a lot safer and easier. On an A65 onlythe left mag needs to be an impulse type. I have used the ancient Case,the Eisemann AM4, Bendix S4RN-21, and Slick at different times over theyears as impulse mags. All worked fine provided they were in good shape tobegin with, and all were available with or without impulse drive. Unfortunately, most are long out of production and parts are becomingexpensive and difficult to obtain. Slick seems to be the preferred typesince it is compact and light in weight, and is available. Often it is cheaper to replace an old mag with a new Slick than overhaul it. A kitconsisting of two new Slicks and harness is available from Mattituck inNew York on an exchange basis. While they are not cheap, you get brand new machinery which enhances safety, efficiency and peace of mind. Igot a kit last year for my Wag-A-Bond because I couldn't repair my Bendixmags economically any more. (Mattituck places ads in Sport Aviation andsome other publications as well, but if you need their address and phonenumber, I'll dig it out.)Graham On Sun, 2 Mar 1997, Craig R.

>Graham,>>Kick backs haven't been a problem, but the C-65 is just hard to >start when it's hot. Craig,Here are a couple of ways I have learned to do a hot start.1) Open the throttle 1/2, pull through hard and retard the throttle as soonas it starts.or, 2) Mags off, open throttle all the way, pull through hard 3 or 4 times.Close throttle, mags on and pull through. It should start.I have used both methods successfully down here in HOT south Florida.Maybe someone else has another method to suggest.Ted Brousseau/APFnfn00979(at)gator.naples.netSunny SW Florida________________________________________________________________________________

Graham,I have my mag switchs on the right side on the Inst. panel for the same reason. I still haven't started it without tying it to a post or something. Maybe it's always best anyway. Got about an hour in yesterday. I tried out a 1930's leather flying helmet a friend gave me. Looks neat, but it's cold. I think i'll go back to my ski hat.Craig________________________________________________________________________________

Ted,Yesterday I stopped for gas and spent 15min getting it going again. The system that worked was, Flood it till it fires and kicks back. Then turn the mags off and open the throttle, pull 3 blades. Then start it with the throttle cracked.Craig________________________________________________________________________________

Hi Craig,I envy you guys being able to fly open cockpit stuff this time of year.You may have told me, but I can't remember where you live. You really sould try to get an impulse magneto; it will make your life a lot easier and safer...especially during hot starts.Cheers,GrahamOn Mon, 10 Mar 1997, Craig R.

Ted,Your local Kmart must not carry this cold weather stuff we have in Pa. A ski hat is just a knit hat that is woven tight so the wind doesn't come through. Polar Fleece is good stuff too. We are down hill snow skiers so we are equiped to keep warm.Craig________________________________________________________________________________
