    Yes Keleo makes nice exhaust systems. I just installed my 200Ti in a Dynaflite Super Decathalon and used the Keleo exhaust that routes to a header behind the engine with exhaust pipes going underneath the plane. Very neat and trouble-free. The 200Ti is a very sweet engine, I just wish it made a bit more power. Mine started up and ran perfectly after a year plus gathering dust on the shelf. To me it seems better suited to the Decathalon.

    Matt,

    I haven't heard anyone describe any upgrades made to the H9 kit but who knows, maybe. I would go over everything described in the thread to be sure. I used 30 min epoxy for joining the wings on both my planes with no glass reinforcement. My first Mustang went in very hard but the wing joint showed no signs of giving way. And the one I am flying now is extremely overpowered but I've experienced no structural problems anywhere. I used the supplied CA hinges and then sealed all the gaps with clear ultracoat. Again, no problems. I am sure that the plastic hinges would work fine too. Try use your thumbnail to press into one of the gear rails- if it is easy to score into the wood that's not good. The retracts you are describing sound like the ones that gave everyone trouble. I didn't even try to use them. I don't know about using gorilla glue for structural joints, never tried it.

    Walt

    Status: offline     		The H9 P51 1.50 size is the best flying Mustang I have owned. I epoxied the wings, used the CA hinges, power is a Saito 180.
    Retracts are by Century Jet. I believe quality landing gear to be a good investment in protecting this plane. I would not use the stock
    retracts.
    Enjoy your Mustang.

    thanks for the tips...I'll look more carefully at all these points and see what needs to be done to my ship, especially the retracts situation.

    happy flying

    Status: online     		Hi matt,take a look at JTEC RADIOWAVE website, they offer a really nice set of functional scale exhaust for the p-51,as for the retracts,don't skimp on that aspect of your build-up,there's plenty of good options to go with...good-luck mopartybob

    I'll check out the JTEC RADIOWAVE site thanks.

    Question about 22 oz fule tank - mine came with the L -shaped type where the main fuel hole is about 1.5 inch back from front, therefore you cannot mount right through firewall (like the flush round trank shown in instructions)

    What are people doing? Do you plug the firewall up with plywood and make 3 holes for fuel lines? Then do you put copper lines through there or rubber? Or do you plug the main hole with an extra rubber stopper and silicon like supplied with the fule tank?

    Also, what is the correlation about fuel line tube level in relation to carb fuel intake level? How high or low basically should you mount the fuel tank... should it all fuel line be parallel or can it be off by 1/2 " etc in either direction?

    Do you also seal inside the fuel tank area with a sealant in case of a leak?

    thanks
    Matt

    Status: online     		Hey matt,as i'm still building mine and yet to cross that bridge your at, I strongly suggest you review the build-up thread on this bird.I have found out thru this thread that the supplied engine mount bolts are tooooo long and WILL hit the front of the tank,as to the level of the feed tube it should be slightly below the carb to prevent siphoning,and YES,fuel proof the engine and fuel cell area just in case the worst does happen,don't forget to thin ca all screw holes for strength,Do not use the retracts that came with this bird,they will not hold up to anything less than a perfect landing,but read thru the thread for the best application available.I wish i could give you more info except READ THE THREAD,alot of the guys there have proven facts as to the build-up and flight characteristics of this plane and you won't be doubtful or disappointed with your end result. the thing i like about the jtec scale exhaust vs. the keleo exhaust sys. is that if you have a hard nose over ,your ex. sys. won't be bent up.(the keleo sys. is hard mounted to the engine,the jtec is mounted via conduit piping off an in cowl muffler.good luck to you buddy. mopartybob

    Status: offline     		I just ran the lines through the existing hole on my first Mustang with the 200Ti. On my new plane I plugged the big hole with ply and cut new ones for the fuel lines. Never trust the length of the supplied screws that come with ARFs. Actually I don't ever use them, I always replace them with allen screws.

    To anyone installing a 200Ti don't rely on the instructions on where to drill the mounting holes. Put the spinner on the engine, line it up and mark the holes. I think the instructions for the 180 are OK.

    The Hangar 9 'Stang really flies great once you get the quirks out. Everything important is covered in the thread. Read carefully!

    One benefit of the YS160 is that I was able to mount the tank on the CG. The balance point isn't affected by how much fuel is in the tank and empty tank landings are noticeably more forgiving with this setup. The engine also fits inside the cowl nicely with just a small cutout for the rocker cover.

    I flew my plane yesterday for the first time in a while. The 160 turns a 17x12W prop 8500 RPM on the ground. I haven't clocked it, but we are talking serious speed. Everyone at the field ended up at the flight line with me, cameras in hand goading me on- lower! faster! A bit of a knee-knocker but lots of fun

    I printed out the entire list and will read the tips more leisurely away from the computer and at my work bench.

    Walt - your plane looks great! did you put the fuel lines through the firwall using copper or rubber tubing? and where/what is the best for personalizing decals on the plane ?

    Status: offline     		I just drilled holes in a convenient location that are a little bigger than the tubing and ran the tubing straight from the tank to the engine hookups. No need to get fancy.

    The lettering on this airplane is just Ultracoat. Script lettering is easy to do since it doesn't have to be exact to look good. I made a pattern on the computer and printed it, taped it down on some covering, cut out the letters with a knife and then ironed them on. For more complex graphics I make drawings using Autocad and send the files to a friend who has a lettering business, but the Ultracoat method is quick and cheap for simple stuff.

    Status: offline     		This thread is very large and I haven't been able to read it all yet. Has anyone put a gas engine on this airplane? If this has already been discussed, can you tell me where in the thread (approximately) it was discussed? Otherwise, those of you that have installed a gasser on this bird, I'd like to hear from you.

    I've been doing a lot research in the Brillelli gas engines thread and their 26cc seems like a possible good fit. This is the Brillelli site

    What gas engines have people had success with on this airplane?

    Thanks,
    Gary

    Status: offline     		thanks again for the tips. I think I'll leave those cool jtec scale exhausts for my ziroli p-51 I'm going to build. Too much dough going into this one right now. Waiting for my robarts to show up now and then I'm close to being done.

    Hey, I have JR 821 servo's on the main linkages and 537's on the flaps. These 537's will not stop buzzing in most positions, even at neutral! The flap got a bit of epoxy in the hinge even though I had vaseline in there...so it's a hair on the "not totally loose" side....nothing drastic I feel. I cut the travel back in the transmitter etc but to no avail.

    Any ideas?

    Mat

    Status: offline     		I read your thread about the radio components you are installing in your P-51. If you are using 537's on the flaps, your asking for trouble in my opinion. They are big and drop down a lot. I think you are risking servo gear failure. I would invest in high torque metal gear servos for the flaps. If one of those servos fail on landing, your plane will be upside down in nothing flat.

    Just a suggestion, I have one too.

    Gus
