Default Preliminary 14MZ-2.4GHz pre-flight and flying tests so far.

Received my NEW TOY, it was waiting for me!

Package it arrived in was good from my viewpoint. Tower really packed the H out of it. Not complaining here.
The tx module is smaller than I thought. With Towers packaging, no way this will get damaged.
Both the TX module and RX were packed in separate foam sheets with instructions in the bottom of the box.
You also get another DIDDLE stick( same as in the 14MZ tool set), a plastic stick would be fine, as all you do with it is push a button to bind the RX. But it is nice, in case your one with the transmitter gets lost or damaged. I am now collecting several of them.

The antenna will rotate only 90 degrees in both the rotation and bend (X - Y planes). Bend the antenna at some angle and then rotate the base, only 90degrees. Good thing here as you do not want to rotate to twisting the cable off.

The current version TX case needs to have the foam cut out by the TX handle on the right side for the antenna, easy to do.

Last night I upgraded my TX to the official code on the Futaba site, all went fine, TX functions on 72MHz
with no problems, same as before.
First thing was to verify the TX reconized the new module. Followed the included instructions, easy.
No problem came up and the wrong freq module screen came up.
Changed the freq to 2.4 multi mode for the new test model with 12 servos configured off the 2 sticks. J1=3, J2=3, J3=3, J4=3 servos each.
Powered up the RX with 12 mini-standard servos in, these are not blazing fast, HS-81, Hobbico CS-11, JR NES241, GWS naro and finally Futaba 9201, 9152's. I will test again with 8 - HS5955TG's in a 36% plane with DA100 running and smoke pump on tomorrow.

The rx just blinked green at me, it was not binded.
I had to bind the RX to the TX, very simple push the button for 2-3 seconds and all done. worked flawlessly.
Nice leds, easy to see for quick indicator. WIll check in bright daylight if not cloudy or gloomy tomorrow.
RX binded now (CA anyone?) and it was off to the races.

Did the wiggle test, all servos moving smooth and nice.
Executed the servo movement test. All servos moving smooth and not jerky.
Everything works as expected.
Tomorrow I will test with 8 HS5955TG's for the blazing speed test.

Now the BIG ONE!
The desk PC up and running massive data xfer over the WIFI router and WIFI hubs to my laptop WIFI.
Two cordless 2.4GHz phones on and connected.
Cell Phone on and connected.
ALL the ABOVE devices are within 2-4 feet of the RX, all servos move nicely with both stick and servo test.
Moved to ~ 30ft from the RX setup, still good.
Everything works as expected.

Turned TX on and executed the Transmit ok.
Went in the system menu and attempted to do the range test with the above equipment still on and running.
The TX screen then shows following: (This step is WRONG as I find out).

Currently transmitting (RF ON)
Range check is unavailble


Well IDIOT (me here), do not activate the (TX transmit on) first, say no and then go into the system menu and do the range test. I have a few things to learn.

Again with all the equipment-devices above running and active.
All servos moved smooth and nice, no drop outs of glitchy movements on ALL 12 servos.
Again ~30ft and no problems, all 12 servos still working fine, no glitches or jerky movement.
Everything works as expected.

Next test:
Another BIG ONE!
Using calibrated power supply, running the servo tests first then second wiggling the sticks(two tests here), I then proceeded to LOWER the power voltage: Power lead wires are less than ~9inches of 20 gauge wire.
5.2, 5.0, 4.8, 4.6, 4.4, 4.2, 4.0, 3.8, 3.6, 3.4, (3.2Volts) OOP's, Very NICE!
At 3.4 to 3.2 the power lead losses with servo current drain, etc the RX then dropped out. 3.4VOLTS!!
Remember there is 12 servos running here.
Repeated this two times running the servo tests.
Repeated this two times wiggling the sticks.
Again at ~3.4 to 3.2v the rx stops working. NOT TO SHABBY!
Seems Futaba does not have a issue here like another vendor. I have my guess why, but I will leave it.

Let the servo test run for 10 minutes, again no problems.
Works as expected.

Time is running out tonight.
I have more tests to do but it is looking VERY GOOD at this time.
Still has to pass a few more tests I can do, along with the flight testing this weekend.
I need to verify that the 14 G3fasst RX will only respond to the TX it is bond to, I need to have a friend help me here with his TX, I need two Futaba TX's for this. Also verify the other vendor's TX does not make RX glitchy. I do not expect a problem from the above tests done so far.
Looks like I will be placing a 6014 RX on backorder shortly. The features/delta between a (8 fasst) to a
(14 G3fasst) RX is worth the extra $ IMO at this time.

Spectrum analyzer checks - looks to be done later.

SW code issues will be something I am not going to focus a lot on at this time, as these will be worked out.
Futaba say's they are working SW on as we speak.

I will update as more tests - flying occurs.
GO Futaba!
Worth the wait, long as it seems. I hope they get the supply moving for all soon.
I did not have to neuter my 14MZ to 8 channels and a dingleberry cable sticking out.

Disclaimer: These are my first hand experiences at this time!

DAY 2
The first test bed, Gentle lady electric glider with PJS1500, custom heatsink motor mount, APC13x7, CC85HV, Medusa 3.5A reg and with 11 extra servos moving also.

Ground check.
Test run full-moving throttle LOOK 87AMPS at 25Volts = 2100+ WATTS of stupid power, the RX is within 7-8 inches of everything and works fine even with the range check test at ~30 feet.
Ran the servo test and let it do it's thing for ~2 minutes, warmed up the motor and heat sink. I had to stop, I burnt one motor up already due to brass balls. Racing my electric gentle lady glider against a 46 gas pattern plane. He beat me in the turns but not on the straight. I had the wing tips flapping like ??? on the straights. The motor let the smoke out on the last leg.
The setup works as advertized.

First flight.
Got in one short 7 minute flight on the hill side here. First time I flew in the open park spaces.
No problems, hard to tell the latency with the glider, but no glitches. only running 3 channels.
