    YS's are pricey here too, but 400+ GBP worth of Laser twin is even more of an investment!

    The Laser is a beautiful looking engine though I've never seen one here in the states. I think the power is somewhere close to the Saito 200Ti twin that I ran, and I found that a 16x10 prop (9000 RPM peak) worked best on the Mustang. Don't try a 6 pitch prop on this plane with the big 4-stroke, as it will barely produce enough speed to fly the plane. Been there done that, and it was a scary flight!

    Is H9 still marketing the 150 P-51 in Europe? If so I hope that they fixed the problems with the retracts and the rails. Based on the experience I had with my first H9 P-51 I wouldn't consider using the retract setup that the plane came with over here.

    I fly over to the UK pretty often since my boss's office is in London. One of these days I am going to take the time to find a good hobby shop and nose around to see what you guys have on the shelves.

    Walt

    Status: offline     		I agree..........I have one with a Saito 180 in it and started with a 18x6 prop....barely flew...nearly crashed it on the test flight. I have since gone to a 17x8 APC...plane weighs 14.75 lbs. with Century Jet Pneumatic Retracts...Plane flies very well now. I am extremely happy with it, I would not even try the stock retracts.

    Status: offline     		Based on posts here on RCU it sounds like the Frank Tiano retracts are a big improvement over the stock units. If you are going to stick with mechanical gear then this is probably the best option.

    I use Spring Air with the oleo struts and I know these work great. The way I figure it, if I am going to pay big money for an airplane and engine, a bit of extra money to make sure the gear works well only makes sense. And the 150 P-51 is NOT the easiest airplane to land so the gear really needs to be pretty beefy.

    I think if you read this thread from one end to the other you will find the most satisfaction with Spring Air and Robart.

    Status: offline     		I have had all three brands. The originals are plastic and break, and bend easily. The Tiano gear is metal and holds up better, but is still prone to collapse on a rough landing. The Robarts have been able to stand up to everything tossed at it so far. No fiddiling with servo throw, and they look better (oleos vs. wire legs). Your mileage may vary.

    Status: offline     		Hey guys... I'm trying to find out which Spring Airs I should use for the P51, the way I read it here
    (and thanks for all the info on this thread!) is that is the way to go with the least amt of work.
    FYI I plan to use the 200Ti (mainly for the sound) even though it is slightly under powered.

    Thanks..

    Status: offline     		I am ready to maiden my big H9 P-51 this week. It has a Saito 180 and Century Jet retracts.
    I was wondering which way the plane pitches when you apply flaps and how bad.
    I have found that scale planes can go either way (pitch up or down)
    Thanks

    Status: offline     		Tom,

    I am now flying my second H9 150 P-51. The first with the Saito twin went in when I lost the radio. My new Mustang is powered with a YS 160 and I made some very good improvements during assembly, but the flying trim setup is about the same as for my original plane. Here's my advice:

    The flaps don't cause any noticable pitch change on the H9 150 P-51 so don't worry about that.

    But, make sure that your plane balances at or a bit forward of recommended. Just a bit tail heavy makes the 'Stang want to float and balloon on landings. It will also make the tail droop in the turns unless you add rudder. The more weight on the nose the better the plane will fly, but there is a trade-off in ground handling unless you sweep the gear forward a bit.

    Make sure to set your elevator rates much lower than recommended. 3/8" up/down is about right for flying and my high rate is around 1/2". Anything over 1/2" is way too much and will make for an exciting maiden. The recommended rates for the other surfaces are fine.

    Start with a 17x8 prop on the Saito. I ended up with a 16x10 on my 200Ti which has similar power. A 6 pitch prop and 4-stroke will not make enough airspeed to fly this plane.

    Good luck!

    Walt

    Status: offline     		Thanks Walt for the tips. I have a 17/8 apc on the Saito. I believe it was turning about 8400 to 8500 rpm yesterday.
    Well I reduced the elevator per your recommendations. Running in the outermost hole in the elevator and the second from
    the inside on the servo (the most inner would bind) I have slightly over 1/2 inch each way.
    Going lower will have to be with end points.
    The CG is set right on their mark w/o fuel.

    I'll let you know how it goes.

    Status: offline     		Tom,

    I just double-checked my elevator rates just to be sure and yes, 3/8" should be plenty and 1/2" still very managable.

    For reference, my Saito twin got around 8900 RPM on 30% with an MA Classic 16x10 and flew very scale. The APC 17x8 worked OK (I don't remember the exact RPM) but I ended up flying at full throttle most of the time to keep airspeed up.

    Let us know how it goes!

    Walt

    Status: offline     		I got 2 flights on the Mustang yesterday. It flew very nice. The Saito 1.80 seems to be enough power. It would fly around on half throttle no problem. I made one diving pass down/cross wind @ full power and it had good speed. I think it was in excess of 100mph.
    I am going to have to practice my take-offs. I tried to go gentle on the throttle , advancing slowly to keep it tracking straight. Well the plane unexpectedly lifted off the ground @ half throttle. I went ahead and advanced to full throttle which caused the plane to torque to the left and toward the other pilot stations. I had the plane in a 30 deg right bank and it was still drifting left.
    The flaps worked great. Walt you are correct. I could tell no pitch change with flaps.
    I must say, all the Hanger9 stuff flys great. Too bad this ones headed for extinction.
    Tom

    Hanger9's I still have. 1.5 size P-51, .60 size P-51, .60 size Miss America (electrified), 1.5 size Cessna 182, Alfa trainer.

    Status: offline     		Tom,

    I very happy to hear your maiden went well!

    I "fly" my Mustang down the runway using the elevator to hold it down until I feel that there is enough speed for the plane to take more throttle (always past the othe flight stations!) With the big YS engine and 12 pitch prop my new 'Stang really wants to go left once airborne but I am ready for it.

    As you have found out the plane is very clean and will really gain airspeed in a dive. Also if you try throwing it around you will find that it will turn a very tight loop, snap etc. like a sport plane. But it doesn't look right for a warbird to be doing that sort of stuff.

    You didn't mention your landings? I assume that they went well? The plane is a real floater for a warbird, isn't it.

    Walt

    Status: offline     		Walt, I was happy with my 2 landings. #1 was the best with only one small bounce. #2 bounced a lot higher but was very controllable. It just settled back down and stayed down. The flaps, in conjunction with the spring loaded struts helps. I just weighed my plane and it comes in at 15lbs. Horizon states on their manual it should be 13 - 14 lbs.
    I really like this "stang" . I can't wait to get back out there. I normally need to get a half dozen flights in or so before I get comfortable with a plane.
    Thanks
