Just picked up the H9 150 sized p-47, smokin deal that I couldn't pass up. Just wondering what kind of power should fly her in a scale fashion. Mine has a hacker c50, not sure which one, planetary gear box. The plane was all ready assembled with everthing in it when I got it. Don't know the gearing, I only run outrunners so this motor is kinda of new to me. I am using prodigy batteries which are a 10c rating, so my numbers are low. 56 amps, 1750 watts on a 22x 12e prop. It has a jeti 90. I weighed the plane and it came out less then 17 lbs. which I was surprised cause it feels heavy, probably cause the planes is built very solid.

I just finished building the same plane.
I'm using an E-Flite 160, Castle Creations 110amp ESC and 10S 5000mah lipos. This is what Hangar 9 recommends.
I'm using a 19/8 or 20/8 prop.
It sounds as though yours will fly OK with 1750 watts.

I think I may borrow a set of TP extremes for the first flight, just so I know I have a little extra power to get her trimmed up. What was your AUW?

What was your AUW?
I don't know.
I built (assembled?) the model and equipped it as recommended by the manufacturer, and it balances properly with the batteries and with no extra weight added, so I assume the power and weight will be within reasonable tolerances.

Looks great, I am leaving the bombs and drop tanks off for the maiden(less drag). I have been taxi testing it and it seems to have plenty of power. Its in the car for the maiden tomorrow morning, hoping the winds are a little calmer then they are anticipating.

Maiden went great, had way to much up trim on take off but got it trimmed up. Landing was fine but a bit bouncy, I had maybe 30 degrees of flaps and it ballooned a little so I landed without them down, plane still slowed down nice.I will dial in some down elevator for next flight, Cg was dead on but I think I may move things around to get more nose weight. I like my planes to fly a little nose heavier then what manufactures recommend, they seem to land easier for me. Had 2 short flights do to the nasty crosswind(maybe 5 1/2 minute total), plane flew very scale on 1750 watts. Put 2000 mah back into my 5000 packs.

Mike,
Nice looking plane, I guess that it is just a bit too big for Rodeo Huh......Glad to hear the maiden went good. You have to bring it out to the fun fly next weekend, just so we can see it. Now I see why you are sellling your large pattern plane.

Maiden went great, ....
Congratulations !
My P47 is just slightly nose heavy, and I have a small amount of down elevator mixed in with flaps. I'll test the flaps up high before using them in a landing.
I'll maiden my plane in about a month or so; this has been a near record year for snow and it hasn't cleared yet.

Mike,
Congrats on the plane and the maiden. After I finish up a couple of ongoing projects I really should put mine together. I have an Axi 5330/18 or Hacker A60-14L, not sure which one to use but either on 10S. I lieterally just got my new TP 4S and 6S 5000 Extreme V2's, I have all the servo's, and the Shinden struts as well. Only thing I want to get is a dual voltage regulator so that I can have the 791 retract servos at 4.8 volts and the rest at 6 volts.

Apr 02, 2008, 02:27 AM
Good idea, I bought mine already put together and it was set up with the flaps on its own 4500 mah battery with a matchbox to really get them synched nicely, the rest of the electronics are on another 4500 mah battery. Servos are all digital, except for the retracts which are those nice 260 oz(I think the same ones you are going to use) at 4.8 volts from jr. I was thinking of running the retracts on 1 battery but I think the amount of mah in this plane is a little overkill(9000 mah), probably needed to get the weight up front for c.g. I run a a60-14l in a large aerobatic plane on 12s and it produces a lot of power(3000 watts) with a 20x10 xoar prop. Would be nice on the p-47.
drksyd
Apr 02, 2008, 03:11 AM
I'd like to get a guage on how much power I can get from the A60 on 10S as I have one more that I may use on a TF giant scale P-51. Since I'm at sea level, I'm guessing a 20x10 and 10S should give me plenty of power without running the amps very high.
mpope1
Apr 02, 2008, 09:39 AM
On 10s I would use a bigger prop, maybe 22x10,21x14, or 22x12. The only reason I was using a 20x10 is because of ground clearence.
drksyd
Apr 02, 2008, 10:28 PM
I already have a couple of 19x10E's coming so I guess I'll try it with the Axi first. With the A60 I'd actually rather increase the pitch so I'll see if I can find a 20x12+ or even a 4 bladed prop.
mpope1
Apr 02, 2008, 11:46 PM
If you find a 4 blader that size let me know. Solo makes some large prop hubs and blades but they are expensive.
drksyd
Apr 02, 2008, 11:58 PM
Zinger has a wide variety of 4 bladed props. According to them, I should be using a 20x8x4. On their website it's a little over $60, I'm trying to find somewhere that has them or another alternative.

Had another flight today, dialed in about 15% down elevator with about 45 degrees of flaps, was right on the money. Plane slowed down nice, no bounce.
Michael in Toronto
Apr 27, 2008, 03:33 PM
Successful maiden; even better second flight with flaps-down landing. :)
It flies great, mostly around half-throttle.
OK third flight, but stalled on landing (from 4 feet altitude - damage to retracts) due to full flaps and too-low air-speed. :o
It'll be flying again in a couple days.

Apr 27, 2008, 05:49 PM
Looks great Mike, had the same issue last weekend with mine. Slowed down a little to much on landing with a nasty crosswind, scraped a wingtip before settling on the mains. Luckily no damage. Just picked up a new set of xps 5000 mah batteries should see a significant increase in power over my very used prodigies.

Looks great..
like the inflight shots
when I do another warbird this will be the one..
on thing I've learned from years of flying warbirds is fly them to the groud with power.. but it's bit me alot of times.. I've gotten really good at fixing retract rails :) .. but there is nothing like a warbird in the air

Has anyone used larger wheels than the ones that come in the box or would they interfere with the main spar? I fly from a rough field. Thanks.

Guys,
I'm sure you will find this thread very useful for this model: http://www.rcgroups.com/forums/showthread.php?t=499371
I came across it last night researching sound systems and details the trials and tribulations of Peter Nichol's electric conversion. The work he does with his CNC cutting machine to make the fake engine crankcase that contains his Hacker outrunner and the speaker enclosure is worth a look. You may recognise him from Q&EI magazine and his many Hanger 9 warbird conversions.
Regards
Peter

Got a chance to get my P-47 in the air last weekend at FEAR, a fun fly in Surprise, Az. The videographer got some great shots, he was using a real nice camera! There was a stiff crosswind, but flew real nice. Almost sold it, I am glad I decided to hold onto it, its rock solid in the air! http://www.youtube.com/watch?v=pYOdsGFSImw&feature=player_embedded

Thanks guys, its a hacker c50-13xl w/ gearing. Not sure of the gearing ratio, but I am running 10s with a jeti opto 99. About 2600 watts on a 21x12 apc prop. The batts are the newer turnigy 5000's, I think I paid 100 bucks plus the shipping from hobby city(they are the 20-30c). Its amazing how much lipo's have dropped in price, I remember buying a 2100 mah 3s for 70 bucks...
Ron101
Oct 09, 2009, 01:17 AM
That's a nice light setup
I'm surprised how nice your performance looked at only 2600 watts
any more would just look silly... I'm sure you can get some pretty good flight times with that setup too
Cool man
I know I can't believe how much Lipos have dropped and they have gotten so much better too... I love my zippys
Really liking the new hyperion G3 35 there some hot packs.. and priced pretty good with a great warrenty
I'm doing a Top Flight 60 P-47 arf right now on 8s... then back to my Gaint Scale TF P-51 and get it finally done!!
later

If you haven't seen the H9 1.50 P-47 and newer P-51, you should take a look at them. They're built really lite despite their size. I've never weighed my P-47 but I'm guessing it's about 17lbs. I'm running a Hacker A60 14L with only 2200 watts and still get a good vertical climb. I have the TF giant scale P-51 and Skyshark P-40 but I'm not sure how an A60 will fare in those.
mpope1
Oct 09, 2009, 09:55 AM
I agree the hangar 9 birds are a lot lighter then others of the same size. I think my p-47 is 17 1/2 lbs. My friend had the skyshark p-40 and I think it was around 22 lbs!
Ron101
Oct 09, 2009, 11:01 AM
I agree I have a Hanger P-51(60) and it's very light and built very well
it's one of the best flying planes I own...
But the Top Flight P-47 60 is a dream plane of mine... I'm almost done with the weathering.. I have all the parts out there for it. So no turning back on that one. I have a A50 16L which I'm going to run on 8s 30c 5000 packs
the arf isn't overbuilt like the the kit.. so I think it's going to do fine
My Gaint Scale TF P-51 is half done.. For that I have a 5345/14 with a 21x14 prop and a jeti spin 200.. on 12s 30 5000 TP's.... in a test run it's making close to 4000 watts :D I should come in a 25 pounds... so about 160 watts per pound should fly it just fine
If I had the spare cash and not so many thing to finish I'd grab a Hanger ( P47 in a heart beat.. for there size, weight , big hatch they are just perfect for a electirc conversion

The 1.50 size H9 P-47 is prolly about done as far as availability. Horizon brought another bunch in a few months back and that may be about it. Unless they authorize another run of them. Same with the 1.50 size H9 P-51. So, if you got em fly em!
I bought one on RCU before Horizon announced they were bringing some more in. And they ARE lighter than most 1/6 scale models out there. Makes a good conversion as I have seen one fly many times done by Ed Couch. He runs the Turnigy 80-100 with 22x10 and it really moves out.
I just keep putting other ARF's ahead of mine even though I have all it takes to put it together. I went ahead and bought some Sierra's cause I am through foolin' with mechanicals. It IS ideal for E-Power with the big top hatch. Plug-in wings are nice for transport too.
It's too bad that Horizon is not doing more BIG warbirds to this degree of fine-ness. They seem to be hung up on the .60 size models.
drksyd
Oct 10, 2009, 05:56 AM
I think I should pick up another P-47. I have a set of Sierra's for it and want to make sure I get the most out of them. The Sierra's are great but for some reason they were about a 1/4 inch short. I had to send them back to be lengthened.
Unfortunately I had a landing incident and plane did a little cartwheel. Result is bent motor mount, one smashed wing tip, cracked the spar and busted fuse former at wing root.
Ron
Do you have the new .60 silver/blue H9 P-51? That's a great improvement over the last version. I'm on my second (old version) P-51, actually Miss America this time. The new ones look great but I hope they fly as good as the previous models.

No I also have the old version (Miss America also) I feel the same way you do I sure hope they fly as nice as the old ones. I see on RCU a guy just built the new version electric ...he used to big a motor a packs. But he is at 11 pounds.Mine is 8.5 ready to fly and flys like a dream on 6s.
So real curious to see how it flys on 6s... he went 8s and a power 110.. way over kill for that plane
drksyd
Oct 10, 2009, 04:45 PM
The good thing about the .60 size planes is that you can keep the wingloading low. A 6S setup is good but I like 7S with little smaller packs, 3850mah for me. Only problem going this route is paying more for a HV controller. I'm flying Miss America with 6S but if and when I ever finish the TF .60 P-51, that will fly with 7S.

I just sold my miss america, It was hard cause it flew so nice! A fellow club member bought it so I gave him a good deal, it had a retractable tailwheel, 4 bladed prop. I really like the new hangar 9 version, but I just dont have room for it!
drksyd
Oct 11, 2009, 12:41 AM
Sure you have room lol. It can take the place of Miss America.

I was doing some testing on some newer turnigy batteries running 10s on my p-47. Reason was I was getting a vibration at full throttle, so I had to take off my prop hub(as in the video). Now I know why I was getting a vibration, on an e-flite watt meter, 21x12 apc spinning on the hacker c50-13xl, I was at 3800 watts/90 amps. Last time I ran some numbers was with the older zippy packs, same set up was 2600 watts/65 amps. I guess I got lucky I didn'
t burn up the motor. I knocked the cell count down to 9, 3200 watts/ 78 amps. I think I can still keep the cg ok on 9s, but I was blown away. These packs are the 20-30c packs, I think I paid about $110 for a 4s and 6s 5000 mah. I ran into a problem on the 30-40c packs on my f-86, which I run at 110-115 amps. Burned up an internal solder joint, my friend fixed it. After opening it up,we were able to see the tabs they use arent the greatest, solder just disintergrated luckily not shorting out the pack. They are using 8 gauge wire coming out of the pack, but internally they need to step it up! Still a good bang for the buck at reasonable amp draws!

Nice video aways back. My Uncle Cliff flew with the 9th Air Force in P-47s
He had 4 air to air kills and a lot of ground missions.
Last week I took delivery on the History Channel's 14 DVD set ( got it on Ebay for 35 dollars) of "Dogfights " and "Battle 360"
Absolutely excellent!
There is a whole story on some P-47 pilots.
The CG video is stunning along with real life interviews of some of the surviving pilots talking about the aerial combat stories being shown on the videos!
14 DVDs , over 33 hours of material for only 35 dollars which included free shipping.
If any of you guys enjoy this sort of thing, get this DVD set!!!
I watch mine on my TV set down in my shop while I work on my airplanes.
