    RE: NEW H9 P51 Mustang 60 ARF

    Well, the firewall broke loose on mine this past weekend. Was flying and came in for a landing and noticed the entire front half hangin down. The firewall broke loose, nearly in half. I quess the glue they are using is not good stuff. I epoxed it back together and am waiting to take it out for a test flight.
    By the way, here is a video of her, taken a few months ago.

    RE: NEW H9 P51 Mustang 60 ARF

    Maiden flight.
    Kit is from 1st batch from Horizon, just got around it this year.
    Overall experience: 8 out 10
    1 issue: Retract support area not enough glue, no glue in important area(s)
    -
    -7 ch. 2.4 setup ( ailerons mixed ) y-harness; flaps & gear.
    -Saito FG20 w/ keleo exhuast, 16x6 apc
    plan to try 15x7, Keleo exhaust robbed about 200rpm
    (stock Saito 8600rpm, ground)
    -2x 6v 2700ma, NiMh
    -throws as per adendum. Rudder at high settings for both low & high rates.
    see horizon site for correct throws, original manual wrong.
    -Balance set by moving batteries. No wgts used.
    -Flaps set on 1 sec delay & slowed about 60% ( digital is so great ! )

    Mods/changes:
    -Firewall re epoxied
    -tail wheel changed to Dubro scale 90-120 size.
    pull/pull on tailwheel
    -Fuel tank change to 11oz, moved rearward about 2-1/2 inches.
    -CG set at 4-1/2", w/ very slight nose down
    -Flaps set to 1/8" down
    -Ailerons set 1/16" up

    *forgot to reinforce retracts..

    Take off:
    4-5 mph headwind, 75 F, low humidity
    Allowed 300' of field.
    Flaps up. Rates low.
    Slow,slow steady application to throttle, tail up quickly guessing 5 mph, slight pull started to left just after that, easily corrected and maintianed with slight rudder. Light on gear about 15 mph, rotation at about 20 mph, slightly past 1/2 throttle.
    So about 175' of field used. Kept it level and straight easily, climb at about 30 degrees, 3/4 throttle. Raised gear, no change in flight. Shallow bank to left, tad bit rudder and elevator...smooth turn, no issues.
    Trim out, 3-4 clicks right aileron, 3-4 clicks nose down.
    2-3 mid throttle-3/4 throttle passes. Steady and tracking like a bullet. Full throttle pass- slight climb as expected.
    Pulled a few hard turns, 70 degree bank, 3/4 on elevator stick, pressure on rudder just slight prior to elevator, smooth sharp and tracked well, nose remained level, no sign of stall or snap out.

    Landing, full flaps. Dropped in from 100' out & 100' up, chopped throttle to idle plus a couple clicks, nice smooth approach, no wobble (signs of stall), nice easy descent rate. Applied a little throttle to stretch landing on main only touch down, propably a little below 20mph.
    Very stable & smooth.

    Right landing gear tore out maybe 10' into roll out...VERY VERY WEAK, as touch down was not hard at all. ( I forgot to reinforce it as mentioned in this forum ) aaarrrggggg.

    Conclusion: Fly it like a warbird should be for take off & landing. She is very scalish for sure. Slow easy throttle, use your rudder. Keep your climb out steady and straight.
    Allow yourself a nice slow long approach. Fly it all the way, gently on low. Matter of fact, don't even bother with high rates ( except rudder for taxi reasons) Keep it scale.

    Wonderful flyer, once tweaked!

    RE: NEW H9 P51 Mustang 60 ARF

    I have been looking to get The hangar 9 p-51 blue nose, but have read so many negitive things about the plane. I see that it is back in stock with horizon again and was wondering if any body has gotten one of the new ones and how do you like it thanks zz

    Why not get the ESM P51?. It's better than the Hanger 9 one in my opinion.

    Cheers

    RE: NEW H9 P51 Mustang 60 ARF


    why is everyone flying with a EXPENCIVE saito Fg-20/21 , while you can use a much cheaper dle-20, is it for the keleo exhaust?
    now i'm flying a BHM , trojan t-28, for my 3th plane im considering this H9 p51 blue noise, but i read a lot of negative comment about this plane......should i buy a top flite ????i like the color theam blue noise....

    RE: NEW H9 P51 Mustang 60 ARF

    The DLE 20 is a very nice motor. My only concern would be the CG with that motor. I have a saito 125 in mine and it balances perfectly. I think with the dle you would come in too nose heavy. Otherwise it would be a good motor for it. I really enjoy mine. I think both the hangar 9 and the top flite are both great airplanes that have their share of issues. What plane doesn't.

    RE: NEW H9 P51 Mustang 60 ARF

    I’m been meaning to do a write-up on this bird for a while. So here we go. This is a very nice airplane with lots of new upgrades from Hangar 9.
    The Pros:
    - New all metal retracts. As far as I’m concerned, these are the best retracts I’ve ever seen. All aluminum construction with working struts to absorb any hard landings. These retracts are so strong, I believe you could destroy the airplane and the retracts would be in perfect working order. No more messing around with the mechanical retracts. Simply install the servos and drop them in. They are TOP-NOTCH!
    - The new printed covering is very nice. I had almost no wrinkles in mine. The scale detail with this covering is unbelievable. See below in the Cons.
    - The overall color scheme is also very nice.
    - The tail surface is air foiled and very scale.
    - Has a scale tail wheel that looks very nice. See the Cons.
    - This is the first H9 mustang that was designed to be flown with either Glow, Gas, or Electric. It has a nice large hatch on top that is perfect for swapping out batteries. In my case, I found it was nice for plugging up all the servo wires while the airplane is in the upright position.
    - The flaps are very scale and very nice on the bird. However, it I had my choice, I would have designed it with just a single flap servo instead of two. Just to save weight. Otherwise, these are top notch Flaps.
    - The fit and finish of the bird is also Top-Notch. Everything just looks RIGHT and Scale!
    - The instructions are also very good and detailed.


    The Cons:
    - While the covering is very nice and I placed this in the Pro category, the down side of having this printed covering is that if you tear your coving, a simple patch is not easy. You would need to buy the covering from H9 and it’s terribly expensive. If you are hard on an airplane and need to make frequent covering repairs, this is probably not the plane for you.
    - While the tail wheel is nice and scale, it’s a little on the flimsy side. I’ve not had any issues with mine, but it is a little wobbly and I would like for it to be stronger. Also, I had a hard time getting the tail wheel installed in the small access through the fuselage.
    - The wood. What can I say, the wood is not Top Notch. I found the wood and glue joints to be weak. During the build I ended up breaking a few of the smaller access panels and such due having weak glue joints and poor wood. In fact, after approximately by 20th flight with a Saito 125, the entire firewall started separating!!! This was very scary. I was able to re-epoxy the firewall and have not had any issues since. This might have just been a fluke, but I was very disappointed. I’ve owned many Hangar 9 airplanes and have flow the CRUD out of them and I’ve never had this issue with any them.
    - The cowling is very nice and scale, however I would prefer the design like the TopFlite. TopFlite has the half cowling, where the bottom half is removable and the top half is actually part of the fuselage. The TopFlite design just looks better and more scale as it has smoother lines. Also, you can remove the TopFlite cowling to work on the motor without having to remove the prop and muffler. With the H9, you have to remove all these items to work on the motor.

    Flight summary:
    - This bird flys just like the scale bird. Heavy! She has a heavy wing loading and you must continue to FLY this bird at all times. Never attempt to slow her down and GLIDE her. This is not like most of the earlier H9 birds that are light and can be flown like a sport plane. This is NOT a sport plane. If you attempt to use too much elevator at slow speeds, or attempt to glide her in on a landing without power, or yank violently on the elevator at any speeds, she WILL STALL. This is exactly what the real airplane will do. She is not a glider. Most of the people who crash this plane simply treat it like a light sport plane and get her going too slow and she stalls and crashes. When I fly this plane I’m always very aware of the wing loading and therefore I never put her into a situation where she slows down too much. On landing, you must keep a small amount of power on all the way in until just before touchdown. You must fly it in all the way. If you are a pilot that is not proficient in making faster, power on landing, this bird could be a bit too much for you. Once she’s in the air, she flies just like any airplane and does wonderful scale maneuvers. Just remember not to pull aggressively on the elevator. One interesting finding, she will do an accelerated stall just like the real plane. When she does stall, it’s fairly uneventful, just drops straight down and pulls out as soon as some speed is achieved.
    - Ground handling is very stable with those all metal retracts. No wobble like most birds with retracts. With a full tank of fuel she can be a touch nose heavy when on the ground. Just remember to use a little up elevator until the speeds are up so she doesn’t try to nose over, especially on grass.
    - The bird just looks GREAT in the air. As scale looking as any mustang I’ve ever seen.
    - I used the Saito 125 with an APC 15X8 and 15% nitro. She has plenty of speed and good vertical. See my attached YouTube video. http://youtu.be/YhsMoj3RMEY..
    TopFlite Vs. H9:
    - I debated this for a long time and ended up going with the H9 because of the retracts and option to go electric with the H9 would be easier, due to the top hatch. I think they are both excellent airplanes. Both have some issues. I’ve never flown the TopFlite, so I can’t really say how it flies.
    Well there’s my 2 cents worth.
    Enjoy!

    RE: NEW H9 P51 Mustang 60 ARF

    I've only used 4.8v on the ignition system and my 2.4 rx needs a 6 volt source....I would think with lipo's today the added weight of one more battery shouldn't be a weight problem (if that is your concern).

    What mAh did you use on the ignition? Im looking at this RCEXL Opto Engine Kill Switch, allows me to use 1 or 2 batts for both ignition and receiver.

    I have a 90-degree bellcrank that pulls the choke closed and when I push it in, the choke opens....I'll try and find the pictures that show how this is done. But in the meantime....take a look at this:

    Thanks! Btw, how do i hook up the landing gear to my receiver? I have an 8 channel radio and rcvr. Tried to follow the manual for a 7 channel setup, it says i only need 2 y harnesses. Now i used it both for the ailerons and the flaps. Do i need another y harness for the gear?

    bboytab,
    You will need one more y harness and a 3 or 6" servo extension and hook it to ch5 on the rcvr. With the servo extension on the flaps, ailerons and gears make it smooth to install and remove the wings. Just remember to mark the extension so you can hook up the right control. I like to make small paper tabs with the name of the controls on the tab, ie flaps, ailerons and gear!!
    I hope this help!!
    BTW: Do they still have the horse track in Laurel?? I flew for a guy who had three horses that would run there back in the 80's.
