neat thing is that you can program practically any aux channel to act as switch for the igintion on newer radios. It is soooo convenient to switch the ignition on or off with the TX
Yep, this is really nifty, but I discovered that with the IBEC for the SAP 180 ignition, and the 2 reg/switches that I am going to come up one slot short on my 7-channel Rx![&o]
Is it kosher to use a ''Y'' lead for 2 of the items, say one of the reg leads into the Rx and the IBEC Y'ed together, or reg and throttle servo??
If not, I think I've got an 8-ch Rx around here somewhere...

Bob,
I think the 7 ch should have enough terminals. Connect the IBE to the retract port, one of the regs to battery and the other to an aux channel. That should leave you with two ports unused. What else are you driving in your set-up??
Frankie Imbriaco came down to the field and help me get going today. Thank you Frank!
Got two in....these were full flights to empty tanks both times. Turning a 17x13 APC standard blade. Performance was really nice. I think I have the mixture settings just about where they need to be or very slightly rich. With the engine only broken in about halfway (about 1 gallon through it now) extended rolling verticals did not sag like they had with loads like the 17x13 provided before. For all practical purposes, vertical is unlimited on the 17x13.
The sound quality on the 17x13 is better, quieter, mellower, than on the 18.1x10 or 19x10. The 17x13 or 18x12 is about max load for the engine and the 10 inch pitches less load. But the 18.1x10 and 19x10 will work great too and produce good overall performance.
It looks like the main needle will need to be about 2 turns, 2 1/16 turns open. The low needle needs to be 1 3/8 to 1 7/16 opens for these higher load props. For sport apps, leaner settings probably will hold fine.
One thing I realized today is that it's probably a good idea to have a dedicated fuel line to the carb and a separate fill line. I've been having problems with losing the prime in my current set-up because I've been using the carb line to fill the tank. This particular Walbro doesn't seem to like that.
A good day of flying. I stole one in the middle of winter.
