kool, was just going to send u message....for the wing you use the quick disconnect right?

GSK

Yes two disconnects , Will bring the tubes out of the wing to a tee then single tubes down to the disconnects , then onto the valve.
Should make for a tidy setup

The major issue is that the wheels sit a little proud of the wing , so will have to think on that for the doors .

I ordered the Mustang today-I have read alot in this thread, is anyone been running a suprer tiger for power? I currently own a ST2500 and ST3000 as well a Zenoah G26 EI-I am trying to choose which engine-I am leaning towards a ST3000-this engine runs smooth and starts extremely easy-what do you guys think that have been flying this bird?

ST3000
Hi-Tec 645mg for elevator
Hi-Tec 5645mg for rudder
JR971 and 971R for retracts
Futaba S3010 for flaps and aileron-is this over kill?
Hydramax 6 Volt pack 2400 for flight pack
Hydramax 4.8 for retracts on seperate jack
Specktrum ar7000 receiver

will this set-up perform or do you think I need to change something-let me know -thanks for everyone's help

Here is setup I have, pretty happy with it so far

JR DS821 all around except...
Flaps Hitec 645MG
Rudder Hitec 645MG
JR971 for retracts with reverse Y-harness
JR 2400 6.0v for servos with JRPVR5203 regulator for retracts servos (no extra battery or swiches or rewiring needed with this $30 reg)
JR 2400 4.8v for ignition
AR7000 receiver

engne is up to you, personally I think nothing else but a 4-stroke for a big warbird like this, cause of sound...but thats it

Not intending to start a flame war over 2 vs 4 stroke but my opinion is i will worry about the engine sound when you can buy an engine for a rc Mustang that sounds like a Merlin. Until then no engine sounds right. So i buy the engine that gives me decent performance at the best cost which for now is a 2 stroke.

I have several large super tigers the 2500 and 3000 they run well, hope they will pull the mustang. The 2500 when running a 18X6W APC prop sounds like a indy car on previous plane, it echos thru the woods that is behind the flight line when making high speed passes over the runway

I had a a ST2300 in a 3D plane. It was quite powerful for its size...but a bit finicky to tune and keep running at its peak.

Frankie 2nd took to the air Saturday and made a great second maiden (after the mid-air a month or so ago). A friend at the field videod the first flight. You can see it on his web site: wyliewarbirds.com at:

http://www.wyliewarbirds.com/video/warbirds.htm

Click on "Hangar 9 P 51"

Unfortunately, the next day (today) she went in on the first flight of the day. It just went into a slow roll and dove into a pond at the end of the runway. Very sad. Had to get a boat to get the ramains. Luckily the engine is fine. The water cushioned the crash. We put the Saito on a test stand and fired it back up right away. The electronics will all go back to Horizon to be checked out. That may have been the problem. All the servos and receiver are from the original Frankie. Might have been something there that wasn't quite up to the task.

I feel bad Karma here. May not rebuild Frankie 3rd !! Frankie 1 went in due to a mid-air, my H9 Corsair went in when the horizontal stab broke coming out of a dive, and now Frankie 2nd; three planes in two month. Not a good summer......

My 2500 was a little touchy as well until I started using ST fuel by Ritch's and I never have had another problem-tune easily and ran great, I think there is less oil content but of course the 2350 is the newer ST and that may not apply.

Rip n Bank

Nick,

I'm very sorry to hear about your Frankie 2! I know how much you enjoy this warbird.

You have a POND at the end of your runway?? Man, that would intimidate the heck out of me!

So, let us know what Horizon says about the electronics; it's not uncommon for them to be damaged by a crash in a way that is not obvious in a bench test.

BTW, had you replaced the crystal in the Rx before re-using it?

Hang in there!

Nick, I am sorry you lost your 2nd one-I would not know how to act and be a just little gun shy

kahloq

I had a summer like that last year. Lost my H9 Corsair due to a flameout and it spun in, lost my Extra 300 almost the same way, and then totaled my H9 Hellcat on its maiden. Those were the three major ones, but also lost my son's PTS P-51 due to a radio lock-out, etc, etc.
There is nothing wrong with taking a break from a specific plane. If you feel bad vibes right now for a Frankie the 3rd, then simply hold off and build something else or fly what you have and wait for something new that might catch your eye. More then likely, we'll see a new 1.50 size plane from Horizon before spring(maybe even by Christmas).
The H9 1.50 P-51s do fly well as you know and I can understand missing that also. Although the P-51 in general is not one of my favorite planes of all time, I sure do enjoy, shall I dare say, the "comfort level" it gives when flying it.....knock on wood! Of course, now that i've said that, something will happen to mine.
But, I was less apprehensive flying the H9 P-51 then I ever was with the KMP ME-109 and still am. In fact i built the P-51 in part to lower my nervousness about the KMP ME-109. I also didnt attempt to fly the 109 until well after the P-51 was flown even though the 109 had been built and ready to go for a year.

frisconick

Thanks for all the kind words. I'll just have to let it soak in for a week or so and decide what to do next. Will keep you guys informed.

Thanks,

Well...another 1.50 P-51 went down today. Not mine, but the electric converted one of a fellow club member. There are only two possibilities for why:
1) he may have gotten too slow on downwind leg for final approach and it snapped and spiraled in......pilot stated he had half flaps on and was just beginning to initiate the bank turn to the left to bring it around to line up with runway. He also said he was at about 1/4 throttle at this time. Please keep in mind, that 1/4 throttle on that plane was the same as slightly more then 1/2 throttle on a glow powered 220 saito equipped P-51. I dont think this is the cause as his plane flies very fast and keeps momemtum well even at low throttle settings.

2) There was noticeable burn damage on the CC85HV speed controller when we recovered the plane parts. My theory is, that the speed controller blew a fet or something thus killing power to the motor. In this scenario, the prop would still be spinning, but only in a windmilling fashion and it could have happened several seconds before the plane actually spiraled in. As such, the plane no longer is maintaining the throttle speed held by the pilot and is losing speed and lift(no prop wash now). But until he started to bank, there wasnt enough speed decrease to indicate a problem in time to recognize it. Its also possible the burn damage happened to the esc when the plane hit the ground, but, there was no burn damage at all on the lipo batteries(nor we're they puffed) even though one of them was severaly smushed up on impact. If the esc burnt up due to the impact, the batteries would have also suffered a voltage spike and that would probably cause catasptophic failure(fire). The burn damage on the esc was under the heatsink and nothing on the esc as far as pcb boards was cracked or chipped or anything which would indicate crash damage to the esc.....except for the heatsink being dislodged.

Anyhow......the plane is not fixable, however, he does have a 2nd one that he was planning on putting a saito 220 in. When he will decide to build it though is the question. He was pretty bummed out as any of us would be. The real crappy part is...it destroyed his two 6s 5000mah batts and they were quite expensive($250-300 ea) since they were ThunderPower brand and so cant even use them in his other helis and such.

frisconick

Bad Karma !! Bummer. I felt bad after my first one and a bit numb after the second. But I can see where that could be a huge problem not being able to hear the engine when it quits pulling. You really don't know to get the nose down until it falls down !! To me, the roar of the engine on a low pass is the reason we build warbirds. On the plus side, I can make him a heck of a deal on a slightly used 220 with Keleo exhaust??

Nick

kahloq

I'll let ppl know about the 220 and exhaust, but this friend already has the 220 from what I understand. Maybe you should hold on to the 220 in case Hangar 9 or Topflite releases another 1.50 size plane soon....like a Corsair, Spitfire, etc.

man thats happened to me more than once, luckly with nuff altitude, but its scary as hell, specially if you cant hear the motor, thats by far my biggest fear with this bird during slow flite, the unpredictable tip stalls.....this is why am trying the ailerons as spoilers now (crow setup) as am told this prevents tips stalls to some extent....i only tried it once but with very little deflection, my frankie is now put away waiting for new shoes (robarts on the way)

kahloq

If he did get it too slow(pilot induced), its probably something he wont ever do again on purpose. he's mostly a heli guy, but has plenty of experience flying planes too. But, a lot of the experience is on aerobatic types like YAKS, or low wing loading planes like a big Tigermoth. He's flown warbirds before, but, if it was because he got too slow, then its a lesson learned for sure.
I've done that before as well. Now, when flying warbirds, even on final downwind leg, not until ive completed the last bank towards the runway and then only when the wings are level do I lower the throttle down gradually. I also usually input 1/2 flaps on the downwind leg and then on the final bank, I go to full flaps depending on wind speed. Not until after the wings are level on final approach does the throttle go below 3/4. I may be keeping more speed during a flight then i need to, but speed equals flying, so, there ya go.

Well I got mine today and am clearing the table-getting started this weekend on the beast

I've been buying stuff along for my plane. I have the EVO35GT2 gas for engine. I'm thinking servos. I have enough DS821 servos new. How are these holding up?? I have enough JR126MG's I could rob from another plane I'm selling. Digital? Metal Gears? Whats the verdict? THANKS,RACJ

duber3

Horizon recommends jr537 servos, 54oz minimum
so the ds821 will be enought at 72oz at 4.8v

[link=http://www.horizonhobby.com/Products/Default.aspx?ProdID=HAN4050]hangar9 p51 150[/link]

Servos:10 servos: 8 standard, high torque (54 oz/in or more); 2 low profile, hi-torque (JRPS791) retract servos
8 standard servos (JRPS537)

Rip n Bank

When you buy the JR-791's for the gear, be sure to buy one of them "reversed." Saves you the grief of a reversing "Y" adapter. If you don't get a reversed servo, you can also have the 180 degree throw go through an opposite arc as the other gear. Regardless, these servos are only warrantied to run on 4.8v.

All other servos except flaps: 60-70oz @ 4.8v (but run them, and the Rx, instead, on a separate 6.0v battery; go back in this thread to see how to wire that up with the retracts on 4.8v).

Flaps: I strongly recommend you operate these "barn doors" on something as strong as Hi-Tec HS-645MG (metal gear; 133oz. @ 6.0v) servos. Not only do they have to deflect, and HOLD, these in a 1/2 throttle airstream at 45 degrees, but also HOLD them in the retracted position under high-speed, positive G loads, since H9's design does not seat them against the wing saddle, when retracted, as they should be.

Rip

RACJ

Thanks guys. I'll go with DS821 exceptfor flaps go metal gear. Already got 791 retract servos. Thanks to this thread I got 1 reversed. I haven't read manuel as I'll fly untill winter then do this plane. Thinking about kelo for the 35GT2 and this plane. I just wonder if it will pass fields noise requirements??
