I think it is interesting that the AMA competitions say nothing about the engine/motor being off for landing, only that the landing be smooth. The flight ends when the plane stops, so I guess the prop can be still turning.
If you have the JMP-2 timer, you could use the final flight speed to turn down the power in a nice linear way, over lets say 10 seconds or so.

So get the F2B guys to be reasonable Ned-088.  Was reading some combat posts via email, and Laird Jackson pointed out that technical stuff like this is supposed to go through the technical committee(which happened for an ill-advised shutoff rule), but that under certain circumstances people can pack the vote if they try.  Maybe that's what happened here.  F2B would be well-advised to ignore the prop, just like AMA.  A more sensible approach might be to require the ground roll after touchdown to be no more than 1/2 lap.  Nobody could do that with the motor still running with any power.

Hi Rudy,
You've got it. Hunt and i have talked about doing this a million times, but since the "setup" was done for the Worlds last year, we had to leave it wait. Spring is coming and you should expect Bob to be descending under power at the NATs.
The blip works in governor mode. I think I had Bob programmed for a pair of 1/2 second long blips at roughly 1/2 the normal RPM.
It was audible and I'll bet you could finish a maneuver through it, though I think I'd bail out anyway.

All the Best,
Dean Pappas

Rudy,
I bought a "Talking TImer" from a RC web site (Model Aviation advertiser) just so I could keep track of time---primarily I was training an RC beginner and was getting tired of making dead stick landings on his "beginner" P-51 (but that is another story). The timer is actually pretty neat. You can set a max time and it counts down. Anything less than 10 minutes gets an announcement every minute on the minute. At less than 1 minute, every 10 seconds gets an announcement, and then a 10-9-8-7.... countdown.
One thing I found interesting was how that first minute after signaling the judges flies by. That's why I plan on setting my JMP-2 timer to wait 30 seconds for the runup. No use wasting watts (what?) on the ground.
Anyhow knowing the time really helps with anticipating the electrics. On my SuperClown with the stock timer, the warning blip lasts long enough that I almost get to make a touch and go before it repowers up for the last lap! Knowing when it is coming is a big help!

Rudy,
Just Google "Talking Timer". I couldn't remember where I bought mine, but the ones that come up look identical to the one I have (only the "Brand" name at the top seems to fluctuate. Anyway the cost I see from Amazon.com (Tel Timer) is listed at $12.95. Pretty sure I paid more than that!

I have been trying to adapt the JMP-2 timer and a Castle Creations Phoenix 35 on the Super Clown. First tried the JMP on the Brodak ESC, but it didn't manage to do anything. Not sure whether the Brodak stock timer/ESC is not using the RC pulse width system (it uses the same rc servo type connector) or whether the arming sequence on the Brodak ESC is special. I am guessing the latter. The Brodak really could use a pot to change the motor speed. Otherwise the only adjustment for flying speed is the prop choice. The Graupner 9-4 isn't a bad choice, but I would like to play around a little more.

Anyway I feel your pain on trying to use the JMP timer with the Phoenix ESC in governor mode. I was trying to program the prop rpm, but trying to keep track of "blips" is hard enough already (while holding onto the plane!) with the JMP-2 without having the ESC average the blip basically out. I guess I'll go back to using a servo to set the throttle %, then back to the plane to see if I am happy with the rpm. I would like to use a higher pitch prop than a 9-4, turning at a slower rpm, but with the plane flying at the same speed. Maybe that will be more efficient than an "egg-beater" spinning at 14krpm and I can get the power draw down. Really would like to use a smaller battery to save some weight with the SuperClown. I think it would help its flying. But basically I am just having fun fooling around.
