What you have is exactly what I am now running in my Super Clown (I just swapped the Brodak Motor for a Scorpion 3014).
I do use the 3s2100mAHr setup and was using about 1700 mAHr last time I looked. Yes it is a little edgy, but since the battery "only" costs ~$47, I'm willing to take some chances! Besides, that was with the Brodak motor--hope I do a little bit better with the Scorpion--but will see!

I am running on 0.012 58 foot lines---AMA "legal". My all up weight is ~28oz (using the 3s2100). My notes say I was flying 4.8s laps at 8400 rpm, with level flying power at ~200watts, peaking to 290 in the verticals. I wanted to increase the lap time by 0.1 sec--it would be a bit more comfortable.

On my JMP-2 (which is similar to the Ztron 2) I start with a 20 second delay, plenty of time to walkout to the handle. The total flying time is setup to fly 310s. I start a 6 min countdown timer just as I initiate the timing sequence (when the 20 s delay starts). I am coming out of the 4-leaf clover when the timer hits 5 minutes. I get the 2 blip warning about 20s later. I am walking to pickup the plane at 5m50s on the timer. Now this is with the Nobler, but the SuperClown is similar (a little faster actually since the Nobler is flying 5s laps.

One thing I like about the Ztron is that you can disable the 2 blip warning.

Another detail is the slow ramp-up and down of the CC ESC on governor mode takes about ~10s to go from off to on andvice versa.

Throttle wise, I think the timer/throttle is set at about 30% (maybe lower) to get an rpm of 8100. On the Ztron that would be a "15" if my memory is correct. (I'll check that out).[added--my notes tell me a Ztron setting of "16" on the dip switches corresponds to a rpm of 9100rpm, so I'm now guessing a 14 or so will get in the ballpark of 8500 rpm.]

Here is a rundown of the current settings in the CC Phoenix 35.

AutoLipo Detect
Soft Cutoff (Heli gov mode always forces this)          50% Brake [off in Heli Gov mode]
Heli Gov HIGH                                                                 0.6s Brake delayed   [off in Heli Gov mode]
Forward Direction                                                           Brake Immediate  [off in Heli Gov mode]
 Motor Start   Medium                                                     PWM rate 13kHz
Throttle Response   Medium                                         Current Limiting--Insensitive
Motor Timing  Low Advance (to see if it is a bit more efficient)
Governor gain   Custom--71                                         Spool-up speed   Custom  10 [as fast as I can get it]

HI JFV!

You say that your RC flying buddies say that: "all my RC designs look a lot like control line planes" .
   Gee, I hear that a lot too!

A couple of things,
1) I'd set my Brake ramp to be medium if you have a hard brake---otherwise it will try to stop the rotation fast--which may not be good for the nose of your plane--but I am not sure.
2) For things like the auto-cutoff, and overcurrent, again I would back off on these a bit---you don't want the ESC to cut off in a vertical climb if it detects the battery sagging below the cutoff voltage. A soft cutoff might save your plane!
3) Not sure about the rpm mode ---because you can play with some things, maybe someone else who has tried it will have some suggestions.

Well, I maidened my new electric today at the District II fun fly.  My first control line flights in 40 years.  Flew pretty well.  A bit of trimming to do but all in all, very pleased.  Playing with the tip weight and the engine off set.  The electric power system worked great.  8600 rpm on the Scorpion motor with a 10 x 7 prop gave a 5.1 sec lap time on 60 foot lines.  I really like the new CC firmware.  Here's a few pictures of the plane and pilot.

I tried to program my timer to give the warning blips at the end of the flight but couldn't get it to work.  Does the fixed RPM mode on the CC firmware disable that feature?

JfV, Very nice lookin plane. What did you use for the finish
