Yes.

Hello folks! Just waiting for the EU distribution centre to have some stock of this and it'll be entering the hangar! I tend to use the Hobby Eagle A3 Super 4 gyro in my aircraft. However as this one is pre-installed and tuned, should I just buy the gyro version rather than the PNP and add my own?

Odd, mine came from the APP store. It's called "Freewing Flight Assistant". When I got it, the Android app hadn't been released yet.

xviper--I found the app in the Apple Store using that name to search. Thanks.

In case you should need it….PERFECT color match:
TAMIYA AS-6 Olive Drab (USAAF)

Amazon or TAMIYA USA websites…

Glider Guy - CG is right where the specs show. I just did not have elevators exactly level. And first take-off, I probably pulled the stick back a little to much. The down trim I put in during the flight definitely helped but I did not have quite enough available. I thin I have that all sorted out now. I have expo in the elevators, may increase it some.

[xviper]

Perfect! Thanks everyone.

Next time someone has this plane out and handy, could you give me the diameter of the prop base plate (next to the cowl), please. One option to inject some zest into my old FMS 1700mm P-51 is to use this new FL P-51's propeller and motor. Since the motor is a bit higher KV than what's in the FMS and the propeller seems to be much more stout (metal reinforcement plate), much higher pitch and designed to spin at the given KV. However, if the base plate is too small or too big, I'll take that option off the table. (Not that these parts are available yet anyway.)

Prop base plate picture with ruler - about 105mm

105mm from the other site.

[GliderGuy]

Xviper - base plate diameter is right at 102 mm +/-
about 4 inches

BL-41….
Where is your CG? Looking for clues as to the pitch-up you experienced.

Just checked my gyro…steady green and all responses to movement are correct.

Thanks,
GG

I did not find the gyro app in the Apple store. It did show up in the Android store. Maybe a different name search would find it in the Apple store.

3/10/26 I maiden my Flightline P-51 today. Flew for a little over 4 minutes, starting with a fully charged battery. Probably used 20-25% of the battery.
This plane came with their plug and play gyro. Flightline claims it is ready to go with this plane. There were 10-15 mph winds from the SSW, right down our runway. I decided to leave the gyro as is for this first flight. The plane was rock steady, all the way down and through the landing. The only hitch in the flight was that the plane went almost straight up after take-off. I got it under control and put all the down trim available in it. Still needed some down on the stick. I know the elevators looked level, but on close inspection they really did have a few millimeters of up.
No video, no one else flying in this weather today.


3/12/26 The gyro in my plane never showed any lights nor did it seem to respond to the TX switch assigned to it. But it was working based on ground test and the maiden flight was really smooth even in gusty winds. After that flight I got the gyro programmer from Motion RC. Connected the gyro and android device. I made no change, but the gyro lights up now. Solid green, blinking green, and off as I move the switch. Apparently that corresponds to full gyro, self leveling (it won't let you bank more than about 20deg, Thanks to Evan for that info.), and off.

I did not find the gyro app in the Apple store. It did show up in the Android store. Maybe a different name search would find it in the Apple store.

Thanks…it was…but several years ago. Ended up in the ER with several prop cuts on one hand from a smaller FW P-38 prop. This much more POWERFUL
P-51 power train deserves its due respect.

If you decide to leave the prop on, make sure the P-51 is tied down extremely well and stay clear of the prop when plugging in the battery for the first time or for any ESC calibration, motor function work!

Good warning GG, I hope that wasn't by experience.

[GliderGuy]

Umm all the newer FreeWing come with that power tap. For afterburner on jets. The ESC has an internal BEC.

Ok…now I know! Thanks…

Yep…works fine just as it came. Power to RX is supplied via the throttle connection from the ESC to the RX.

WORD OF CAUTION. Very early in the instructions the prop assembly is screwed together and attached to the motor shaft. WAIT WAIT WAIT to attach the prop until you bind the RX and calibrate the ESC and get the motor running correctly.

DANGER! Messing with the throttle, TX settings, and ESC calibration with the prop attached is risking personal injury worst case or at least you risk damaging your plane as it jumps off your workbench when you didn’t expect it to come alive at full power!

[GliderGuy]

Mine arrived in perfect shape. HOWEVER….the UBEC is nowhere to be found.

Disregard…see next post.

See photo as to my confusion…no UBEC was attached where I am used to finding it…just this open ended connector.
