Well I think the point is well taken that electronic ignition gassers should start easily without an electric starter. However, I have my Miller/Dynatron in a plastic tool box with both batteries and tools for my plane assembly on top. It's just not that hard to carry it along with my transmitter case. I used this setup from day one on my DA 100 and while it may not be necessary, it gives me piece of mind knowing that it will start easily and safely every time. If you do a search on here, you'll find guys have been hit by electronic ignitions even wearing gloves and it hurt them pretty bad.
Its not that I don't understand how electronic ignition makes them easy to hand start, I just don't like taking chances with my hands.
I do agree with you 100%, better safe than sorry. There is an extra safety factor when you use a starter. On the other hand my experience is that when you turn the choke on and use the starter some engines will flood very easely. I have done that more than once. Another reason for having starting problems is overpriming the engine. My ZDZ 40 when correctly primed and choked will pop after a couple of flips, then it will start after three or four flips unchoked. That's why I prefer the hand start method.
