Actually, it's an either or situation. My -6A has the old method of assembly and hasn't come apart, yet. If you have the older style brace, and have it already past the point of no return, I'm not sure I'd worry with it. There are hundreds of tip-ups using the old configuration. Mine hasn't come apart, yet. Of course, it could fly apart on the next flight. :-) I wonder why they made the change?

One other idea is to put a magneto that goes 0 degrees BTC and use it to start the engine. That confirms my experience with a IO-540 with a mag and Rose e-ignition. If I start with both ignitions turned on, I often get kickback. After having replaced a starter ring gear, I now employ the procedure starting with the mag only, then immediately turning on the e-ignition when it catches. No problem.

I need to fine my EI manual and read up... I have an Electroair ignition and an impulse equipped mag as well. I always start on the mag. My theory is that this tests both systems every flight and offers me a way to get the thing started with a hand prop in an emergency with the battery dead (the flight would be on one ignition with no electrical -but if you're stuck in the backcountry... or need to flee a hurricane) I have a small 12V sealed backup battery going in along with the Dynon (don't like the internal idea).

The preheater does make a difference in the willingness to start AND there is a difference in how quickly the engine starts when using both vs mag only.

First STOP: You will break something soon, OUCH. As you mention, reduced electrical power during start with dual electronic ignition can be a problem. It is not uncommon. Electronic ignition (Electroair) are sensitive to low volts for proper operation. A large Capacitor or an extra battery as you suggest can eliminate this issue. You may have other problems, but it sounds like a prime cause. Inductive electronic ignitions like the Electroair do need more juice to work than CDI ignitions.

I lied, it is an Odessy 925, not a 725. Since it fit in the box for the old lead acid, weighed about the same as the old lead acid, and given the dual electronic setup, I thought it prudent to go as big as I could. The plane has Sensinich fixed metal prop and is always preheated for anything less than 35 degrees. I've tried the "crank then switch on method" and haven't had any kickbacks but it is pretty awkward as this is also a fuel injected plane an I have to fidget with the mixture at the same time. After digesting these and the responses on the RV-list, I think I'll try the second battery approach and as suggested, supply one ignition system from each battery. I can leave the ignition powered by the main battery off for starting. I feel that second battery is useful from a safety standpoint on a dual electronic plane. But that being said, I can't wait to get something like a B&C or that new inline starter on the plane. I've missed a few flights due to starter issues and never had any other mechanical issue with the plane. Plane foolishness to leave the boat anchor on there. I'll let all know what happens....

Just wondering if anyone has had problems with a master relay from Van's? >>>> Hi Dan- Not familiar with Van's relay, but I doubt it's much different from any of the others. These things are pretty stone-simple, and I would suspect your problem is elsewhere. Have you checked all of your connections to verify they are tight and that all crimped connectors are solid? (yank them wires!) Particularly the wire from the relay to the master switch and its ground. Also no ground paths at the master switch terminals (or loose switch) where they might short to the panel or adjacent stuff. Does anything happen when you jiggle the master switch? (possible bad/corroded switch contacts or weak spring) Does it happen only when the engine is running, on the ground, in the hangar, only on Mondays and Thursdays? Can you beat on the panel or firewall and cause the dropout? Assuming a Main/E-bus configuration, does anything on the other bus drop out as well? If your starter contactor is fed from the master contactor, I doubt you have a problem with the contacts in the master as these things carry all your starter current sucessfully (assuming you've cranked the engine) A decent diagnostic may be to connect some kind of audible device (cheapo jap shack buzzer, car radio etc.) to one of your e-bus fuses (or other points in your system as you narrow it down) and starting at the battery, start yanking on connections/wires following feed paths (including master switch connections) to see if the audio drops out. Ditto for all grounds. Hope some of this is helpful and good luck!

At about 150hrs. Bought a new one from Van's. Problem went away. Let me know if you find a higher quality unit.
