Quick Question: When range testing, the engine goes full-power when signal lost. Does anyone know how to program the stock ESC so that it either kills or idles the engine if the receiver loses signal?
Thanks in advance for your suggestions.

What transmitter are you using??

I'd rather take a look on the failsafe function on your TX/RX set.

Not usually.

The ESC needs a signal from the RX to do anything.

If you just plug in a Lipo pack to the ESC that is connected to a motor only, you might get a beep or two but no rpm.

Add a receiver and you can control the operation of the motor using your TX. Take away the TX or the TX signal and the reciver will defalt to TX settings when the RX was mated to the TX (Bind procedure).

Most radios default to low throttle position--some let you decide. Mine are set to a low, but still running setting so that I know I have lost connection. I don't use the DX6i very often. Can you set a sysyem level throttle position???

Don't wory about that question. Please try this and tell me/us what happens. Just put your throttle at low position and rebind and then switch off everything.

Take out the bind plug--Put stick at low throttle, switch on TX, Plug in LIPO.again and test the motor. Then just switch off the TX. It should all stay quiet.

Hold onto the aiplane while doing this :-)

Regards,

Eric.

Hi Eric- yes, that fixed the problem instantly. Now when the receiver losses signal, the engine goes to off. Much safer now I would think.

I must have originally bound the receiver with the transmitter on full throttle(thinking that would help set the throttle range)

Thanks again for the full explanation and assistance!
Take Care

So it's cold and snowy here and time to inspect and maintain all things rc. I took out the edf unit in my Stinger and after 50 or so flights the old fan was dinged up. I ordered a couple of new ones and put them in the test stand, hooked them up to my backyard vibration analysis and found the new fan not balanced, big surprise eh?. Using the clock method, I was able to get it sounding pretty good. I know using the ipod is probably not 100%, but it definitely helps. After balancing, the fan has much less vibration and is quieter. The first video is just installing the fan on ther motor randomly. The second video is after some tuning. Time to do the habu next.

Don't think I could justify $10 plus shipping for every stock edf unit I have. Took me around 20 minutes to clean this one up. Not perfect but I don't believe that's possible with these stock units. If you purchase a power upgrade from Don or anyone else, then of course have them dynamically balance it. These cheap units ($12) don't need much to make them run a little smoother. Just my opinion.

Cheers

and if u are willing they can be made very smooth, but the motors must be balanced also.

Agree, the stock freewing motor is unbalanced. I don't want to open the motor up so I just clock the fan to try and cancel the imbalance. Break in the weather, might try to sneak out for quick flight or two.

Cheers

The weather cooperated enough to get 6 more flights in. Fingers got a little cold but all went well. Sounds a little quieter wot, I think the motor bearings will be happier anyway. Feeling the itch for a 4s setup, anyone have any good power upgrades to recommend?

Thanks

The RCLander Red Velocity 4300kv alloy EDF is a great upgrade. It also draws only 47a, makes 1200g of thrust, and balances perfectly with a 2200mAh pack.

That setup is hard to beat for a solid upgrade. Only recently have I stepped up to Don's badass Wicked Plus HET units.
