I,am flying version 2 off new grass field (still alittle ruff) have not seen any signs of retract mount rails not holding up. The 220 starts easily with a high torge starter same as I use on heli's
idles just fine without on board glow. I did use dave brown spinner 20 x8 apc prop 15% cool power only thing to watch for is plane will leap into air (almost to soon) but flys and lands very well very easy warbird to handle


TOFLY,
Thanks for the great info on flying the new big stang from Hanger 9. I haven't even started my 220 yet, but I've been wondering about using the on board glow and how to start it. My lhs quizmaster starts his by getting it primmed up and then flips it backwards. WHOA! That just doesn't seem right but I guess I'll try it. Nice to hear it leaps off the ground and the 220 Saito does the job.

DANG, I LOVE THIS HOBBY, CAPTAIN RON.

Status: offline 		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.

Status: offline 		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!

Pat,

I agree on the adjustment comment. 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.

RIP N BANK,
I broke in a Saito 100 this last summer. Put two tanks through it on a break in stand. I got everything set perfectly. 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.

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"...

Status: offline 		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?

Status: offline 		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...

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.

Glad you guys liked the sig!

In my situation, its actually true. My wife no longer notices when I add a new plane and I'm not about to mess that up!

LOL!

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
