Default RE: My 1`st Scratch Built Airboat,,EVER !!

Hi Guys. Thanks for the compliments. I haven’t touched the hull for a little while .Figuring out how to make an engine stand for this ,so ,I had to sleep on it a bit. I think I have something doable know though....

That header and Muffler is for my TopFlite 60(62"wing, 1/8`th scale) sized Corsair.. It`s the SuperTigre version.Meant to be Firewall mounted.. When I bought the kit on the Box it stated the part numbers for the SuperTigre engines in-cowl Exhaust System which is what you see in the Pics.. Since the Printing of the Kits Box it was found that the exhaust was too Restrictive for the S and G-90 Engines and caused overheating. This system works Fine as is for the "Baby engines” but for the Big Boy, She’s a No Go. I ordered this system through my Local Dealer and waited 1 year of getting the Next week ,next month it will arrive B.S., from them. I had known of the Problem of overheat but I wanted that system anyway. I finally found it at Great Hobbies on line Store. They had the Header, and were able to get the Muffler brought in, and shipped out to me. I can’t tell you how happy I was when that Stuff was finally sitting on my Coffee table. More than a 1 year Wait, mostly, because I was being Jerked around.. Oh Well, got the set-up now.. I guess you’re wondering ,why I would want parts, that I know won’t workout for me.. Simple, there’s no problem using the Header," as is". The Muffler needs attention. I’ll do 1 of 3 things:

(1) drill another hole, for a 2`nd tail pipe then Squash the ends just enough to have back pressure for the Fuel Cell and no Heat problems (play with it)..
(2)cut the Tail pipe completely off. Drill another hole same size as the current tail pipe, and join the 2 holes to look like an oval, Find I larger diameter tube that when squashed to an oval shape fits the new hole in the muffler. Then again Squash the outlet till the Backpressure is good, and No heat issues (play with it)..
(3)use the Factory muffler as a pattern and Scratch build another muffler of the same type of Design, out of Brass.. I love the Sound of Brass exhaust systems.. It has a distinct definite Sweet Tone (ring) to it. I made up a Dual Shotgun exhaust system for a guys Triumph 750 cc Motorcycle With that Bike running beside another 750cc Triumph with the same style pipe set-up made from Steel(factory) you could easily distinguish the Brass pipes over the Steel.. Hmm, Maybe that’s why we don’t see any steel Saxophones, and Trumpets.. LOL This makes me feel guilty. I haven’t touched my Corsair in more than a year.. The kit is a F4U-1a/d and I’m scaling it into a F4U-5.I had to take a Break from all the fussy little details. I’m scratch building the correct cockpit for it, and the littlest things have become such an obsession for me.. I’ve done all the research on the Details, have the Game plan figured out for that, even have a good start on the construction of it. Got the Dash panel done( recessed, replicated gauges with red backlights and a sliding Map tray. Have the pilots seat ,With, Leather padded & working folding armrests done. and of course since the Aircrafts interior was all aluminum, I had to make it that way too.. Crazy Nuttso.. Eh? LOL couple of pics showing a few of those details. So anyway, I had to take a break from it for a while before I had a complete Mental Meltdown.. LOL.. Here’s the Stupid thing.. I haven’t finished the 62" kit and I went and bought the Big Brother to it @ 1/5th scale & 86.5" wingspan [X(] and I’ll most likely detail the Bejeebers out of it too.. Crazy Eh?..

..So here I am in the Airboats, Less Stress, and finding it fun, and still able to do a few Scale sort of things on these projects. I’ve been admiring jasperrc Coroplast boats, and the Various Foam core Boats., some of you other guys have been making .I want to give 1 of those projects a try next..
