Been looking at this particular warbird from day one, The looks and performance is scale as it gets, once you get the P-factor and landing technic's down, it should be a very smooth dorsal flying warbirds.
Updated: The manual I originally found had the wrong motor and prop listed. I have corrected the specs and re-run the numbers in eCalc.. According to the manual, it weighs about 9 lbs. With a wing area of 808 sq-in, the wing loading is about 26 oz/sq-in which isn’t too bad. eCalc says that the stock FMS 5060-360KV motor in the V2 version can handle the 17x9 prop and will give a level flight speed of 62 mph, a power-to-weight ratio of 208 watts/lb, and a thrust-to-weight ratio of 1.82:1. It should climb great, but won't be terribly fast. If I increase the KV to 450 using the custom setting, eCalc says I'd have to decrease the prop diameter to 14" to keep from burning the motor up. Just for fun, I set the battery to 8S and eCalc said I had to decrease the prop diameter to 13" to keep the stock motor and ESC from burning up. A higher KV motor would help the speed, but will need to be larger and require a heavier, higher capacity battery to keep from shortening the flight time with the stock 17x9 prop. I think I'd leave it alone and enjoy it. It's way better than the FlightLine 1410mm P-51D I bought a few years ago..
I’m not sure why they list a 10x8 prop in the manual, because that’s patently wrong. The prop this model uses is a 17x9, but as you’ve asserted, the problem really is the motor. At 300Kv, it would be much better on 8S, assuming the motor can handle the wattage. Otherwise, a higher Kv motor (in the 500-600 range) would be a significant improvement.
@@sgcdialler Yep, I’m seeing 17x9 at various websites. I’ll redo my calculations. A 500-600 KV motor would have to be a larger size to turn a 17x9. I think a 400-450 KV would be more reasonable.
BTW.. Cavitation is a phenomenon in which the static pressure of a liquid reduces to below the liquid's vapor pressure, leading to the formation of small vapor-filled cavities in the liquid. Since an airplane propeller doesn't cause the air around it to change from a liquid to a gas, cavitation isn't the correct word. An airplane propeller makes that sound because its blades are stalled. We've called it cavitation for years, but it's not really correct. As someone said, "A lie told once remains a lie, but a lie told a thousand times becomes the truth."
Love the FMS warbirds. I almost bought this 1700mm but settled on the 1450mm version of the same for transporting. I've owned 4 of them. Flying the Red Tail. V8 version now and have a 2nd new one in the box (insurance policy). Non of my FMS 1450mm have had the main strut problems you mentioned. Probably because they are a little lighter. But the P Factor on takeoff and landing rollout is equally challenging.... Always wants to veer off track and hard to keep straight . I did bump my motor up to the next FMS size motor... the 580kV as a drop in replacement to the stock 540. Just that simple small swap out made a huge difference in vertical climb out power.
I got this as my first plane lol. I haven’t put it together yet or anything. It’s a goal plane for me. I practice with my aeroscout for now and a few other more beginner friendly planes like my carbon cub s2 and T28 Trojan 1.2 but I’m always staring at the box dreaming of the day I finally maiden her. Thanks for showcasing her, most of the videos I can find about this plane are years old lol.
Jon , You are rite about the retracks , the struts are mostly plastic , they can be broken , easly , Been there , Done that , I had issues with the inner gear doors with mine , not clearing the tires , an not fulling closing , No RENO Speed runs !! I used an 5000 , an " doctored the lower part of the hatch , so I could move it rearward a little more , made a difference !1 It would slow for landing , with no flap's needed , wit the prop mod , had an upline of 400 hundred plus feet , slam it an go !! so many guys saw that , I sold it , an made some money !! How about that !
Im not confident enough to fly it this way but you definitely demonstrate that it can be done. i preferer all the torque the stock motor has rather than giving it higher RPMs with a bigger motor. Why challenge the manufacture, Thats my moto . thanks for the vid
I'd love to see you fly a Hobbyking Funfighter from a few years ago. 600mm(ish) wingspan and a relatively cheap 150mph with an upgrade to motor/esc. They sharpen the reflexes, trust me!
Personally for me, and in my own opinion from experience, the 1400mm to 1500mm warbirds are much better all around birds to own, transport, and fly. I've owned and still fly the V7 FMS P51 1450mm Mustang, and all I've done is upgrade the 4s esc and motor to modern standards since it was underpowered from the factory as well. Also, many of the guys I fly with rant and rave over the Eflite 1.3m P51, and I can pretty much agree since I've got the same size Eflite F4U Corsair, but my two favorite and most stunning warbirds that I own and garner the most most attention at the field, are my Eflite 1.5m Folke Wolfe and FMS 1.5m P47 Razorback.
Learning all kinds of tricks from you lately! 😜 I've had this one for 6 years, initially everyone was flying it on an >800 gr 6000 mah, which you can imagine added to it's under powering, so eventually tried a 4000 and it flew much better without much time loss. Then went to Danny's standard 5300 at 684gr and it flew nice. Haven't thought to try the HiV 4400 (didn't think it needed the higher C like an EDF and the HiV 5300 is 730gr and didn't want more weight), but after seeing this video, next time out I'll try the HiV 4400 which weighs the same as his standard 4500 did. If you know offhand, where are you balanced, I'm at 125mm, maybe too nose heavy, but with tail dragging prop warbirds, I tend to be closer to manual recommendations, unlike EDF's where I like it 15-40mm further aft. The FW 1600mm Corsair and Spitty are over powered and need the extra nose weight so an SMC 6200 works perfect and gives flight times over 10-12 minutes, but I'm sure you're better at throttle management than me. 😤 The Corsair with exaggerated landing flaps needs to be landed at 45% throttle, similar to this P-51. The Spitfire is lighter and lands at 32% throttle. I also have a sound system in all of them and the Merlin really makes the P-51 sound great. 👍 Gotta check out your other videos as well.
Jon , Theres an easy prop mod you can do to it , an get a very good change to it's performance !! You might try it out , Thinking you would be happy with it , Mine had the 360 motor , , after the change , On HELL OF A UPLINE !! Did not overly effect the flight time , pack ws good for 4 to 4: 30 ..........
I enjoy mine, but had to change the main landing gear for a more powerful one, as retraction was not good. Some foam cutting must be done to relocate the battery, as CG is too much forward. It’s an old model in FMS catalog, and new models are with better hardware
Its funny how the old warbirds feel heavier. I did the same thing with the eflite fw190. Thought it was really heavy when i picked it up and was surprised it was only 8 pounds with battery. I was guessing 15😅. Those strong tendacies for ground looping are why i dont fly my taildragger war birds much. Been too impatient to get that nailed down and just bring out the jets😂. Im inspired though to give it a real go to master that p factor ground looping.
We were going by the FedEx package info which was 20 pounds. Hard to believe the total packaging weight was 10 pounds on top of the weight of the plane.
I have this FMS plane still in the box! I don't want to assemble it till I get my skills back after a 27 year hiatus. I plan on using Specktrum 5000mAh 30C & 50C G2's Li-Po's in it. Jon, what are your thoughts on replacing the wheels with robarts? The stock ones are suppose to have ball bearing's in them, but not sure of that yet. Thank you in advance Jon! 😃👍
Pffft that's barely 20cc size. :) Nice plane! Tbth unless you buy a real high dollar arf or build a kit yourself these things are now nicer than most of the budget arfs. And it doesn't hurt that it takes an hour to get them ready. Thing is begging for a sound system! For more power you can probably change the prop out. I've had great luck just with simple prop swaps after running ecalc. If 18x12 clears you get 230oz thrust on a 2 blade with 72mph vpitch.
Beware because i have the FMS 1700mm Ferocious Frankie and I've had it for about 8 years and after a while the aileron hinges wear and start to tear way from the wing so I used ca fiberglass hinges and now they will never tear away again.
I have both the new upgrade 1700mm Corsair and the Tigercat. both those models have the fiberglass connecting hinges on the aileron and elevator. I'm disappointed, FMS didn't make the effort to upgrade the hinges on this 17.0mm P-51, but still its a pretty impressive model to have
nice video of this amazing P51Mustang; I have the same one and would like to know which CG to you have? it seems that the centering is very backward? maybe i am wrong
Great video Jon! I was wondering what’s the benefits of using AS3X on these kinds of airplanes? Would love to hear your opinion. On EDFs, I totally understand and use them since I saw your video (and I helps a lot)! But the warbirds are much more stable.
There's always benefits to having a gyro that's properly configured. Turbulence-related instability can be significantly alleviated with a gyro keeping the model stable and tracking like a full scale aircraft. While bigger does fly better, it also doesn't hurt to have the plane automatically correct for turbulence.
control horns screws , was ugly , it flys , !!!!!!!!! Again the prop mod is easy , some spacers on the spinner backplate to increase the pitch of the blades , Makes a difference Bro !!!!
Taking off is difficult with taildraggers unless you're used to applying rudder to keep the tail straight to avoid ground looping. It's a dedicated skillset in full scale flying.
Just pulled the trigger on this P51 Mustang and made the purchased through your site from FMS, been eyeing it for years

P-51 radiator was badass. It produced boost by tapering the heat exhaust out the back end creating a heat force.

It's also a 3D maneuver!
Wow, she is a beauty! Nice job and thanks for sharing.
upgrade the motor and she flies so much better!
What motor did you put in? The Corsair 1.7m motor? Cos that's been rated for 8s.
Nice video. I notice my eflite P-51 1.5 flies much better without the drop tanks. Thanks for the review.

There is something to be said for transportability, but the huge scale makes for quite the presence in the sky.

Another excellent video guys!!!
I would recommend a 1.5 from E-flite that Mustang is sweet and with it being on 6s has all the power
Nice work! love me some P-51!!
That’s a red tail mustang flown by the Tuskegee airmen in WWII.
I enjoy mine, but had to change the main landing gear for a more powerful one, as retraction was not good.
Some foam cutting must be done to relocate the battery, as CG is too much forward. It’s an old model in FMS catalog, and new models are with better hardware
Bigger may be heavier but lift scales by a power of 2! You gain far more lifting power at more speeds than a smaller craft
your video's help, thank you
Nice job guys beautiful aircraft , y0o0u can really see it! 👍👍

Replacing the wheels isn't a bad idea at all.
Gentle giant 🎉 that thing is so cool but a bit underpowered yes 😢 well done for that review bro
Definitely a bit underpowered, you're not joking.
Cross wind ? Tail drager? Hold. My beer he says.
Minus the Lipo Battery you use the plane is roughly around 9 lbs dry
Right, so 10lbs is accurate given the battery. Hence the on-screen correction. ;)
I have been eyeballing this bird for years. My biggest question is, how does it come apart for transport? Is it easy or a giant pain in the butt?
It's not difficult at all.
Pffft that's barely 20cc size. :) Nice plane! Tbth unless you buy a real high dollar arf or build a kit yourself these things are now nicer than most of the budget arfs.

No idea offhand, we just shoved a 4400 battery all the way forward.
Maybe as it showed on the manual ( 120mm from the leading edge) 🤷♂️

Can u make a video review about the Mig21 80mm? This is a model i like most, thanks!
It's discontinued, so that's not likely unfortunately.
Does that one have the new 360kv motor or does it have the original 300kv?
Check the link in the description. It should have the current info.
whats your thought's on a 18 x 11 prop on this
No idea. A motor upgrade is a better idea.
Very cool. Kinda want to get one. Not sure what P-factor is. As in P-51?
Google P-factor - it's the tendency of an aircraft to pull left (usually) with throttle.
So...why is it called a "hot swap" vs just a battery swap. I do it all the time, is it not recommended?
"hot swap" is terminology we use that means "we're not waiting for the ESC or motor to cool down, we're going right back up immediately"
Does she have true to scale laminar flow wing design or is it a falsey with a leading edge wing?
At this scale, airflow is almost entirely laminar.
Did you have a mix of elevator with flaps for landing ? Im flying the 1.5 eflite on the sim and having a hard time landing without ballooning.
You should generally always have a mix of down elevator to trim the flap setting.
Thanks for the heads up ! I'm still learning the ropes !
control horns screws , was ugly , it flys , !!!!!!!!! Again the prop mod is easy , some spacers on the spinner backplate to increase the pitch of the blades , Makes a difference Bro !!!!
I’ve tried to fly a plane like this in DCS World. I crashed it trying to take-off. They are hard to fly.

I fly a 109 without a license.
🪪
Power saves planes. This plane would not be saved. Looks nice though.
Not sure what you mean here - saved from what?
It has good power and thrust to weight, but not a lot of speed.
Beautiful, A bit ofa of high price point for me. sorry.
