RE: NEW H9 P51 Mustang 60 ARF
If sailfish can't run a Saito ......any Saito ,then he doesn't know much about engines. Saitos are so easy to start , break-in , and fly , hell I know some people don't even bother to break-in they just fly them, they are that reliable. Sail fish needs a little instruction. The 125 is exceptional ...........aske anyone who is an expierienced RC flyer , they all say the same ...............only beginners that don't know enough will have any problems ,,,,and that would be with any engine........................

RE: NEW H9 P51 Mustang 60 ARF
Ya in my post on the previous page I recommend throwing the kit wheels and tires away , and geting any 3 1/4" Robarts...............as for the Saito manifold , I have broken 4 or 5 of them , the problem with Saito is for this engine configuration the cheap way is to hang it of the side , but the Saito mufflers are heavy so if you don't build a small wood bracket , mounted to the firewall that you can tie-wrap ( I use steel ones from elect department Home Depot), the weight wil brake the header pipe after a few hours. I just did this in my Miss America , I installed a nice support bracket on the Bluenose so as to satbilize and support the muffler, and it will last a long time . I agree when I got my Bluenose in the air I was amazed at how solid it felt , and how well it tracks,,,,,,I think the best pro , and I have tried alot , is the 15 X 8 it gets you the highest rpm , and good torque , my 125 gets better every time I fly it..................................ZDS

RE: NEW H9 P51 Mustang 60 ARF
I don't have alot of expierience, I started with the H9 PTS P51 , crashed a couple of those , then I got a Miss America, and have had it for 5 years , I have not got alot of time flying but I am very comfortable flying Miss America, and it gave me confidence to go on to the Bluenose ,,,,,,,,which is very more Scale like to fly , you must have a long roll on take off and a scale like climb out . After that it is a dream to fly ,,,,,very much more stable than Miss America.........and your right it looks so nice in flight . Here is what I know on the construction of both the initial kit and the new one: The new kit has some lightening features in the wing root first rib has pretty large cut out holes, the Canopy has some lightening holes in the base flange , and some in the bulkheads, I dont think these features amount to more than 4to 5 ouunces. Here is whaat I don't understand they did absolutely nothing to reinforce the langing gear mounting blocks in the wings. I had ordered a spare wing set when I bought the first Bluenose so while I was waiting through all those delays for the second one , I renforce the wing and landing gear mounting blocks , and installed a set of Robart retracts , and 3/8" Robo-Struts (installed retract servo ,control valve , and air tank in the canopy it's almost on the CG) ,,,,,,,,,,,,this saved the weight of a servo , and the heavier kit supplied retracts ,,,,,,,,,,,,this is why I had to put two transmitter batteries forward of the fire wall. Also throw the wheels and tires from this kit in the trash ,they are defective , the wheels will disintigater in fuel vapor, use any correct size (3 1/4") Robart wheels and tires. CG is best balanced at 4.5" aft of the leading edge as measured next to the fuesalage , and most important , the Elevator throw should be not more than 1/2" ..............these parameters have been well discussed and they are what I used and worked well. My Bluenose is between 11.6 and 11.8 pounds. This web sight has all the information for this plane but you have to jump around a bit. Building RC airplanes is a tinkers trade , and this one requires alot of tinkering , but as others have said if you get these main items right this is a great plane . I am not good at putting pictures on this site ..............but I will try............ ZDS

RE: NEW H9 P51 Mustang 60 ARF
The weight I saved using the Robart Retracts made the airplane very tail heavy , so when I added weight to the nose I wanted it to be usefull m the to battery packs gave me a perfect cg AT 4.5" 11.8 LBS..........................2BIRD'S WITH ONE sTONE.

RE: NEW H9 P51 Mustang 60 ARF
H9 Bluenose P51 is a challenge to build because you have to correct alot of poor design and cheap hardware. The new version of the kit though it has some lightening features , the landing gear is troublesome , and the Robart system saves weight , and functions must better. The biggest and most important mod is reinforcing the landing gear mounting blocks, this makes the gear capable of sustaing a pretty hard landing which my sixth flight ended with , but it didn't hurt damage anything . This is a really good looking airplane if flight and the saito 125 with a 16x8 prop moves it pretty fast,,,,,,,,,,,,,,,, Radio ...............Spectrum DX7 Recever Batterys 1ea. 2700 ma 6v 1ea. 2300 ma 6v both mounted forward of the fire wall under the engine mount box.

RE: NEW H9 P51 Mustang 60 ARF
My first flights with the Improved Bluesnose went great, 6 flights great performance no issues ,last landing I let the speed get too low so I got a litlle bounce . The Robarts work great ,,,I also have the same ones on my Miss America. I started with a 15X8 MA Prop , but it seemed slow , I changed to a 16 X8 and that really made a big difference,,,,,,,,,,,fasssster !! zds

RE: NEW H9 P51 Mustang 60 ARF
Thanks ,,,,,it was great to get this airplane off the ground ,,,,I flew my Miss America all day while most of our club guys were preparing the Santa Maria Tri Valley Flyers air field for a Imac meet the next week ....................unfortunately the Saito 100 in the Miss America broke the exhuast manifold at the theads on the cylinder head side ,,,I have had this happen 3 times I think I have to secure and soppot the muffler it must vibrate the header and crack over time , One thing I must pass on .........if you are building the Bluenose P51 balance it at 4.5 inches, I did this by strapping to 6 volt battery packs (2300 & 2700 JR "s) just in front of the fire wall srapped under the engine mounting box. It balances perfectly with a 15 X 8 prop...................this way you get extended battery time and CG balance too............2 b1rd's for one. ZDS

RE: NEW H9 P51 Mustang 60 ARF
Had our local expert pilot maiden flight my Bluenose today at 11.8 lbs, 125Saito with a 15x8 MA prop , Robart Retracts and Robo-Struts, it flew great with a little up trim on the Elevator , didn't use flaps or retract the gear I will fly it tommorrow for that, I used a Dubro Tail wheel on the rudder , instead of the kit set up and it worked well. I flew my Miss America all day m but tomomorrow wil be all Bluenose ..................... ZDS

Could not find any props on the Tru-Turn web -site ??, but looks great on you plane ,,,,,,,,,,,,,,,are you using a Saito 125? ..................and what Fuel 15% 20% or 30% nitro?? I may be doing a first flight on mine this week end , planning to use a 2 blade- 15 x 8 prop , with the Blue spinner, the plane is about 11.8 lbs and balanced at 4.5" CG ZDS

RE: NEW H9 P51 Mustang 60 ARF
Id like to put some pictures in this but I can never work that out ....................I used the air Up / spring down retracts with the 3/8" mounting hole for the 3/8 " Robostrut for a 3 1/2" wheel . I also used the Robart air system with the small tank and the simple 2 port valve ,,,,,,this is a pretty reliable system when you learn how to use it. What size was you 4 blade prop?

RE: NEW H9 P51 Mustang 60 ARF
I just finished my second Bluenose , the first one with the 125 Saito did the classic pitch -up and auger in on take off ,,,I'm certain it was a rushed take off and climb and exasburated with a bit tail heavy CG. Second airplane is also a Saito 125,,,,,,,,,,,,,,,,,,,the new kit has some lightening holes in the canopy, fuse , and wing root end ribs, so it is some what lighter not more than a 6 oz's id say. What bothered me is that the landing gear mounts are the same .....no reenforcements . I used Robart retracts on mine as I did the first one , I belive the whole set-up is lighter than the kits original especially if you get Robart wheels and tires ................the kit wheels disintegrate when fuel touches them, they are worthless. I had ordered a replacement wing with the first kit, so while wating months for the seconf kit I completely built up the second wing , with the Robarts , and when I got the new kit I transfered the lightening hole pattern from the new wing end ribs to the built up wings , and cut them out , when I was done with my Dremel they looked exactly the same . Then I apoxied them together , I did not do that with the first one , and I'm not so sure it didn't have some thing to do with the first crash. The airplane is so tail heavy with the stock Blue Spinner , and a 15X7 2blade prop , I put not one but two 6 volt battery packs just infront of the fire wall where I covered those 2 big holes, used double back servo tape , and a nice velcro strap with buckle . So with a 2700 ma , and 2300ma pack using a Y connector to the Batt connection on the reciever I made my balance weight pay. This configuration gave me a 11.6 lb plane, which balanced at 4.5" . My only concern now is the prop size , I would like to use a 3 blade , but with the True Turn 3 blade spinner which I did drill 8 holes in the back plate to lighten it bumps it up to 11.8 lbs , and the CG will need 5ozs in the tail......................I love the aluminum spinner and 3 - blade bu it's Heeeeavy . I hope to have our expert pilot at Sant Maria Tri Valley Flyers maiden this airplane , I have been flying my Miss America for a long time now and I am good with it but it is a floater compared to this one.

RE: NEW H9 P51 Mustang 60 ARF
I might be mistaken , but that CG looks very very nose heavy, I pay close attention to CG ,,,,,,,,,I know this one is furthe forward , but you have here does not look right to me, I have set the CG on PTS's , and Miss America, and they fly great straight and level , and float in on final , and flare ....................they look nothing like this .,,,, I think its nose heavy and you might see it on advancing the throttle on take off.
