Hangar 9 150 P-51 Mustang

[Heli1-2]

Hi

O.k Anyone that can actually convince me that this plane really slows down well for landings like say maybe and extra or an edge, from what i've read it does slow down well, but who's to say that the talk isn't just marketing hype.

I really want the warbird, but am sceptic of it's landing and take off characteristics given the history of rc replica's and the guys talking bad things at the club about Mustangs in general, having flown the small hyperion one myself, i'm still sceptic for i've seen how bad it can get on a too slow approach, even though the H9 150 size Mustang is bigger, the weight also is increased upping in size.

I have the p-47 150, it slows to a crawl on landings at 17 lbs.

Hi,
How many cells are you powering your P-47 with?

Thanks,

Sean

I'm flying the P-51 on a 80 by 100 mm HXT on 11 cells and its a sweatheart landing with or without flaps at 17.5 pounds. It's not an Edge or 3D type bird and honestly if it handled like that I would not be flying it. It's a warbird and has to be flown all the time. No chop the throttle, drop the flaps and fall into the pattern. Fly it carrying power all the way to the deck at a shallow angle and land on the wheels and let the tail fall when it decides too. When flown correctly I get no pitch change even when full flaps (45 degrees) are deployed about half way through the base leg. Again its always a swallow approach carrying the necessary power to overcome the drag of the wheels and flaps. No three points here or you will leave the gear somewhere behind the rest of the aircraft when it comes to a slidding stop. At this weight they don't bounce but shed parts.

I also fly the big P-47 at 19 pounds with the big HXT motor on 12 cells and its a haus also. This is a simple conversion to do and works like a champ. Again, the approach is low and the base and final are shallow. I prefer a full flap approach but in a high wind never go beyond 20 degrees or first position on the DX-7 radio. This vehicle is several pounds heavier than the P-51 and is flown a little differently but the landing are still the same.

If you want something that lands like an Edge you had better get one as either of these two will not. ed

I run a hacker c50-13xl on 10s 5000's 22x12 apc about 2700 watts. I have flown on as little as 1700 watts and it flew nice and scale, but not as fast. I agree on the landings but do to the light wing load compared to like a top flite(probably close to 24 lbs. with the same w.s.) they do slow down and aren,t very mushy at slower speeds.

[Heli1-2]

Thanks for the detailed information, no three point's, so one has to be carefull not to nose it over and at the same time not for it to touch the tailwheel on touch down, quite a balance that needs to be adhered to.

Reason i want this plane is because it's a 'real' plane not an edge, extra or other sport plane built for airshows. The Mustang looks just right in every aspect, fuse, wings, and retracts. Prop 4 blader would be just perfect.

I'm concerned about landings hence the question i asked. It's a plane that i'd like to fly not worry if i'm going to put it in, going to the field each time. Does crosswinds turbulence make for tough landings or will it cut through it rather nicely straight through to touch down?

So it needs to be landed on the mains only you say.

Will it be possible for someone to do the 4 blade job on the prop like in the rcu review?

What would they ask?, i hear that the plane is a bit of a hassle to put together due to things not lining up 100% I'd have to get someone to build it, building my helicopter was enough for me, i enjoyed it but won't do it again anytime soon, i'm someone that likes to fly more than build,

though if i need to build a plane/heli, i do but take too much time getting things perfect usually, but it's not something i really enjoy doing :)

[Heli1-2]

Any last words of encouragement, i'm swopping out my Big Voodoo Condor Glider for this Kit, tell me why i shouldn't, I've setup a meeting tomorrow at the hobby store for the deal, always time to change my mind before then? Otherwise i'll probably go for it.

[mpope1]

I am not trying to talk you out of it but if this is your first warbird you may want to start out with something a little smaller and less money. If you have been flying warbirds then I would say go for it, the bigger planes fly better just more of a hassle carting them around.

[Heli1-2]

Nope I had a Small mustang, before mentioned above hyperion one, It did fly very nice but it did not land very nice :)

Basically it' needs to land fast, and it was a problem where i flew. I would consider myself a intermediate flyer, Flying lots at the slope, fast planes at the field and a few heli's, My only concern is this Mustang's Take-off and Landing characteristics, for i am now convinced that it slows down well. Looks like i'm going to do the trade then.

Thanks

[Heli1-2]

Well the deal is done and i'm hoping that i made the right choice, will be putting in lots of green ones to get it running. :(

[MustangP51]

ok, what u gonna power her with? tell us how it goes!

Thanks

I fly the big Hangar 9 P47 (electric). Also the smaller P51 and other big warbirds.

I can assure you, in the air, these warbirds are a joy to fly. They are rock-solid stable, even at slower speeds. Just don't go too slow or they can stall.

If you take off and land from a smooth surface (even a very smooth grass field), then you should have no problems.

If you take off and land from a rough and bumpy grass field, you may have problems bending landing gear and breaking props.

[m898]

I have one these, also with a Hacker 13XL on 10S.
It lands very very slow. I once had to belly land it because one of the retracts didn't work and everyone who saw it come in and touch down softly was simply amazed.

there was no damage at all to the plane ! and it only skidded less than 1m which gives you an idea about landing speed.

My P51 with batteries and bombs weighs around 6.5kg. I am about to fly it on a 4 bladed prop.

With regards to take off - it doesn't nose over but I must hold right rudder and always lift the tail. I throttle up slowly because the motor and prop can produce a lot of torque spin. This is noticeable in flight when I gun it and the plane rolls slightly

Landings - i have never used flaps and considering removing the flap servos. It never noses over but just before slowing to a stop it veers to the left.

[Heli1-2]

Mustang51, at the moment i'm looking at an axi 5330/20 or 5330/18 running on 10s batteries wherever i can get the batteries least expensive, yet light, powerful and reasonable good quality.

m898, thanks for that: Wow sounds like it really slows down nice, tell me, can one predict the stall as it unfolds, meaning would one be able to notice it and apply throttle and corrective control inputs to get it going say for a go around if required. Before something bad happens.

So it turns just before it stops, strange, so i'll have to add rudder to keep it straight on landing end as well. I'd like to add the 4 blade prop, is there anywhere i can get a 4blade prop made rtf, with the stock spinner somewhere?

No flaps, would've liked to use them, though i hear everyone seems to say it's not needed. I'm still a bit concerned landing this plane due to the experience i had with the hyperion p-51, though i know that the big h9 mustang has been reviewed and everyone here says it has good landing behavior, or at least it lands slow which is a big help already.

Though it's not too late for me to back out and get say a big extra/cap or edge... i wonder... Anyone want to try and talk me out of this one may still be able to, i do however like the mustang more.

[Ed Couch]

I fly both the P-47 and the P-51 from Hanger 9 and honestly the flaps work well in both aircraft. Advice is just that and all folks seem to fly a little differently especially when it comes to warbirds. I've flown RC since 1962 or so and something almost all my life so what is nothing to me could be a major problem to someone with limited airtime in a high wing loaded aircraft. I've flown scale 104s with damn near no wing and they flew great but it handled differently and required a little care when landing. The large P-51 actually is a little too light for me and I prefer something a little heavier so it isn't too much of a problem in a crosswind. The same to be said for the Jug but that's simply me. Treat it like a fullsize plane and fly the pattern dropping the flaps to about 15 to 20 degrees on the downwind and letting her settle into a nose down shallow approach carrying whatever power is needed to maintain smooth controls. Don't slam the stick around or you will bit it bigtime. I deploy the flaps to 40 degrees after rolling base again maintaining sufficient speed to maintain full response and go for the first third of the runway not in front of me. I carry power until the mains touchdown and very gently bring the elevator back to full aft and maintain the aft position until I'm in the chocks. A lot of folks, especially those flying lightly wingloaded aircraft will crab all the way to the deck but with the Stang its better to approach wing low into the wind with minimal crab angle using the rudder to keep the nose down the runway. Let the upwind leg touch first and she will track herself down the runway with just a touch of rudder. Don't be afraid of cross controlling when necessary. This is not rocket science but technique. When the wind is up, keep the flaps up and come on home but always fly a consistant pattern. Make it a habit. You learn more in the pattern than you ever will boring holes in the sky. The birds are a hoot to fly but will not forgive you when you get careless.

[Heli1-2]

Thanks for your insight Ed, i'll keep your advise close to mind when off to maiden the plane. I think what i must do on maiden to give me more assurance is to just take the bird up at altitude and see how slow it will fly to determine stall speed, i will not use flaps on the first couple of flights, how does it behave on stall?

Thanks for the Photos, definately one to be proud of!

[Ed Couch]

I spent the afternoon flying both the P-51 and P-47 plus a large VQ KI-61 Tony. Winds were in excess of 20 knots with about a 20 degree crosswind component but still managed a couple of flights on each aircraft. Did I use flaps, no way Jose! I flew the crosswind wing low and touched down wing low on all landings. The Jug and the Stang had no trouble taxing at 18 and 19 pounds but the smaller Tony would not come crosswind after landing without nosing over. It was a great day and everything worked except the damned landing gear on the Stang which come out of the wells under g-load. Landings were ok but its still a pain in the backside and I'm about to change them out for a set of Robarts with offset struts and 4 inch wheels for flying off of grass which i prefer.

As far as the stall, its a warbird and flying wings level and gently bleed off speed nose high will fall straight ahead but do it with a wing low and it will take a little altitude to correct with rudder and ailerons. She will snap in a heartbeat when the rudder and elevator are pulled hard cause I've done it a couple of times to see the results. Two turns very quickly but put thing back in the center she will straighten up. Fail to release the stick and she will tuck her nose and spin like a top. Keep the power on and fly out is the best advice I can give. On the Jug, she will let go also but not quite as quick. I did snap her accidently the other day at the top of a stall turn just before I rolled inverted to split S out of a climb. It happened very quickly and surprised me by going to the outside of the turn. I put the sticks back to the middle and eased back on the stick and powered out in about 3/4 of a turn. My flying partner noticed it and another flyer caught it as well. Asking me later what happened. Dah!! Ain't going to get to slow anytime soon. The Jug handled beautifully this afternoon giving me no trouble as well.

The Jug goes by the handle "Thumper" and has the bunny on her nose. I include a few picture of her taken this afternoon. ed

Now you got me all shaking worried about stalling the bird :( And Should i get the robarts right off the plate? When you say wing low on landings, does it mean one wing touches the ground upon touchdown?

[Ed Couch]

The wing is kept down into the crosswind slightly to keep the aircraft from drifting across the runway. Directional control is by applying applicable rudder to compensate for the wing low condition. This is full size technique constantly being practiced throughout ones career while flying the larger aircraft. A wings level full crab to landing is not the best technique for landing a heavy aircraft as speed is your friend here. I just recently dinged a friends big Zero in just a condition in a heavy cross wind. I got distracted and failed to maintain my ground track throughout the landing and lost my airspeed just above the point of touchdown and fell the last foot or so wing down. A 22 pound bird does not bounce and I trashed the wing. ed

Ask rccraze (http://www.rccraze.com/videos.html) if he got any video of Sean Plummers P-51. I have seen the plane years ago(AEF 2005) and it was a real nice plane. 125mph at full throttle, and landed really slow with flaps.

16.5lb if I remember right. there is a thread on it here somewhere :)

I've never landed the Mustang with flaps or even used them !!.
It lands slow and can fly slow because its not heavy - only 6.6kg flying weight (less than 15lbs !!).

I think this is the lightest electric converted Hangar 9 to date.

Swinging a 22" prop it has endless vertical.

Never nosed over on landing or takeoff

Will post a video of just the mustang later

Heli 1-2, if youre not convinced that the plane is easy to fly and lands slow then I suggest dont get it. Honestly. If you built it light planes are always nice to fly over those heavy pigs.
