I need some advice on props. Can you guys help me get the optimal prop for this plane. I have a 1.80 SAITO and the book says that for scale with this engine 16x8 would be ok. However, on my Hellcat, I have a 1.25 SAITO and it also says a 15x8 is ok for scale. Now, also for the 1.80 the manual says it is ok to go with an 18x6. The reason I ask is that the 16x8 looks tiny on that big Mustang. What prop size do you guys think is the best for the 1.80 and the 1.25. The 15x8 on the Hellcat seems to be to much pitch becuase at idle the thing wants to take off. I had this problem but have made successful flights. I hope you can understand my jumbled questions any help on prop size would be helpful since I feel like I'm not selecting the right prop for either of these engines. Thanks. Tom

I also have yet to start my 220. Maybe after this 8th snow storm in a row that is currently hitting us is done. I have GOT to take a break from the 'Stang and fit skis to my old high-wing trainer! Anyway, I haven't uncovered anything definitive in other forums on the following question: if one is planning to INSTALL & RUN a particular Saito inverted, should it be BROKEN IN inverted? I don't think it matters, but now's the time to be sure!

It does not matter. Just make sure you have it adjusted right or it will never run right as with all inverted engines. Pat

I took a "well broken in" Saito 100 and installed it (inverted, obviously) in an H9 60 P-51 and spent LOTS of time, and flights, getting the high-speed and idle mixture just right. Could only pull it off with a hotter glow plug, though. Bo

Mounted the engine on my Hanger 9 P-40, put 20 or so flights on it this last summer and never had to touch the needle valves, high or low. I love my Saitos. I only hope this new 220 is as good as my 91's and the 100. I'm definetly going to break the 220 in on a good solid break in stand. Atleast two or three tanks, or 40 minutes as the manual calls for before we go aviateing. Just can't wait to hear this big 220 come to life. DANG, I LOVE THIS HOBBY, CAPTAIN RON.

Captain, I'm amazed you didn't have to reset your needles after you inverted the 100! Mine took alot of adjustment, but now, it runs like a dream. I have a solid, heavy engine stand, so I'll break in the 220 on that. I'm planning to run up to two gallons of 20/20 through it before it's bolted back in the 'Stang for the maiden. Can't wait to hear it's exhaust note! Rush's "Red Barchetta" defines this as "Mechanical Music"...

Well, I'm finally getting ready to join the wing halves together! Is anyone else concerned over how short the hardwood spar is? I know there's a corresponding box section internal to the wing that it bonds with, but it sure seems that a plane of this weight, wingspan and likelyhood of pulling strong positive G's would incorporate a longer spar. I recall that a couple of flyers, who posted in the original H9 1.50 P-51 build thread, fiberglassed the bottom seam where the the wings halves joined, then recovered that strip with silver ultracote (part of it's hidden by the radiator scoop, anyway). It seems like that precaution would greatly help disperse the tension the epoxied bottom seam is subjected to when pulling positive G's. Any of you planning on doing such a reinforcement to the bottom of your wing? Bo

BankYank -> RE: New Hangar 9 1.50 P-51 Build (2/4/2007 12:14:07 AM)
RIP N BANK That is one of the best sig lines i have seen[sm=lol.gif]

reincarnate -> RE: New Hangar 9 1.50 P-51 Build (2/4/2007 2:08:40 AM)
Didn't glass mine, but may as an option later. I did ultracoat my seam though. If you get a good coverage with your epoxy, and remember not to get carried away, you'll get a very strong joint. That will carry your load. The glass is more for pretty in my opinion, it won't keep it from coming apart if its gonna come. My build is complete as of today. Now I can only sit and stare at her and try to figure out how to shave some weight off her apparently bulky frame. No scale (dead batteries) so I'm not sure how much she weighs, but i'm guessing high 15s. Had to move 4500 6v rx and 1600 7.2v ignition batteries behind servo tray AND add 3oz to tail (*sorry bankyank, I lied to you on accident*) Running Evo 26GT up front with Pitts wrap inverted, large Evo ignition unit and Dave Brown spinner (4 coats Cub yellow 3 coats clear flat) so even with lightweight Evo, it adds up. Will try to get weight up as soon as I can. Its just too da@# cold to go out today (3 deg f at 8:45 PM check local listings) Pics absolutely refuse to upload, so I'll try later. Edit...I agree. That sig may become my new credo. I think you may be onto something...[:)]

captainron -> RE: New Hangar 9 1.50 P-51 Build (2/4/2007 3:50:19 AM)
RIP N BANK, No plans to glass mine. No plans to reinforce the gear rails. Just plan on following the manual to the finish except for the Tony Howard mufflers. Got my Dave Brown adapter XL finally. Spinner now mounts up to the big Saito like it was suppose to. love the sig also. Now I gotta come up with a better one....................CAPTAIN RON.

RIP N BANK, No pics in your gallery. Lets see some pics of all those rip n bankers in your hanger. I showed my wife your sig, she also got a hoot from it. She immediatly went to my shop and started counting. I've got two NIB arfs hidden. UPS usually stops for lunch. Big boxes coming out of the back of a ups truck seems to cause her to go into her screaming ( what the hell did ya buy now) mode. I'll be glad when I get to that safety zone were she doesn't notice the new ones anymore. Spent last night painting all 12 stacks on the Tony Howard muffler. I'm just real nervous about doing the fill and sand work with the micro balloons and epoxy. Not one of my forte's. Suppose to be 50 degrees here today. My buddys' bringing his breakin stand over today. Gonna try and get the big Saito to talk to me. Gonna try a big high torque elec starter first, just can't make myself flip that rascal backwards and then try and get out of the way when she fires. I post tonight how it went. DANG! I LOVE THIS HOBBY. CAPTAIN RON.

reincarnate -> RE: New Hangar 9 1.50 P-51 Build (2/4/2007 2:45:55 PM)
Cap...you'll find that epoxy work to be about the easiest mod you can do. Just do one side at a time and don't get in a hurry. PM me if you want or need to check. I'm guinea pig on this too. Messed up first try and thought Tony was getting another 35.00 from me. Take your time and go slow. UPS guy tends to send me into screaming mode too. "He's here! He's here! Sweet baby Jesus, he's here!" Poor guy's used to it now, but the kid's still go hide. Pics one at a time. Sorry, only way I can get them to upload.

And...

reincarnate -> RE: New Hangar 9 1.50 P-51 Build (2/4/2007 2:52:26 PM)
And finally.... Sorry to take up the space. Anyone installing the Evo 26 or 35 with inverted Pitts, notice exhaust cutouts on both sides of cowl. Ferocious Frankie decal went on right side of fuse because of size of cutouts. All I have left to do is flat clear coat entire plane to take off the shine and seal things up. Already cleared spinner and chin cowl, and one coat over exhaust manifolds and airbrushing, thats why it's a little different shade.

I LOVE THIS HOBBY. CAPTAIN RON. Captain, Wait a minute! You showed her my sig? And she then went and counted your planes?? WHAT were you thinking??? Men's hobby secrets such as this are to be more closely guarded than those of the NSA! Shape up, man!! [:D] As for deliveries, I've mastered the "on-line track package" service of all the major carriers, and know to a high degree of certainty what day "THE BOX" will be left on the porch. My wife and I both work, so that's the day I eat lunch at home, and/or make sure I'm home before she is in the afternoon! There is, indeed, an art to this! Yeah, I've been lax on the gallery thing, though I've posted numerous pictures of my planes in other threads. Will try to upload some soon to the gallery. Frankly, being only 2.5 years in the hobby, I only have seven planes, but fortunately, that appears to be enough to confuse the "enemy!" So, I've finished scratch-building my scale exhaust stack (I'll post pics and technique soon) and am about to paint it. I assume the "fill and sand" work you and Rein are referring to is due to the curve of the fuselage/top cowl where the angled manifold w/ pipes are to be situated. Sounds like Tony recommends filling under each end with epoxy/micro balloons, which I'm considering. Are you cutting away the ultracote underneath so as to attach directly to the thich balsa sheeting? Alternatively, I may laminate opposing wedges (tapering to center) of hard balsa under each end of the manifold, sanding to match both the outline of the manifold, as well as the curve of the fuselage. Yet, another alternative is to trace the outline of the manifold on the fuselage, trim off the ultracoat, and hog out the center "hump" just a bit to get a flat surface to which the manifold can be mounted. Still not sure which one I'll do, yet. Rein, your finished installation of Tony's exhaust looks great! Do you have any construction pics taken from when you were doing the fill and attachment? Bo

NICE MUSTANG I WOULD LIKE TO INSTALL AIR RETRACTS IN MINE NEED SOME HELP

reincarnate -> RE: New Hangar 9 1.50 P-51 Build (2/4/2007 7:02:51 PM)
Nope, no in progress pics from exhaust build. Tony send you both the bases, which are built flat, and you mold to the form of your fuse, and all the stacks, which you basically have to fit-up, paint and install. Rip, maybe the resin/microballoon would work for your exhaust? I'm honestly curious to see how you built yours. And yeah, you cut off covering and epoxy(30 min) the shrouds on. I soaked the area I uncovered with thin ca pretty good. That balsa is pretty thin.

Hi there Flying Hillbilly - here is a link to the original H9 150 P51 forum, look at my posts 569 and 571 which tells you what Robarts I used along with some photos of the installation. http://www.rcuniverse.com/forum/m_860947/mpage_23/key_/tm.htm

That being said, if you're set on moving to air retracts anyway, and you're looking for LOTS of posts on this subject, check out the ORIGINAL version P-51 build at http://www.rcuniverse.com/forum/m_860947/tm.htm. All 32 pages of it! Gear was apparently a big problem with that earlier plane and most contributors apparently upgraded the gear, with lots of suggested brands and installation advice posted. Hope that helps, Bo

OK, Captain, After your earlier post, I got off my butt and took some indoor shots of my "hangar" and posted them along with one outdoor 60-size P-51 shot I already had. Nothing but construction shots of the !.50 P-51 so far, so I'll post pics of it later when it's assembled. Once the tons of snow on the ground melts, and it warms up a bit, I'll replace my gallery pics with outdoor shots. Bo

reincarnate -> RE: New Hangar 9 1.50 P-51 Build (2/4/2007 8:34:33 PM)
Hillbilly...Hope I'm reading wrong and you're thinking about putting in the air retracts as an afterthought. That would be tough but not impossible. Just out of curiosity, why are you going air? Just curious I promise. The stock gear is one of the best factory arf setup's I've seen. By the way, love the screen name. Its classic.

Spitpilot -> RE: New Hangar 9 1.50 P-51 Build (2/4/2007 9:00:57 PM)
OK, so where are these shots?
