Status: offline 		Ok, with a span of 14 ft 8 in and a fuselage around 10 ft...wow. This is my lunchbox- a cowl for a mosquito bite tri-pacer-(the fiberglas one)-and the start of the project. Bare bones- lots & lots of sticks - 1/2 inch sticks. I really got in a rush -went to move it -and wow-you should have seen the pile of sticks.

I't just that this is an exciting thread.

Status: offline 		Tri-pacer builder:

Great job. As a builder of giant scale, I can appreciate what you are doing. I assume the scale is about 45% - is that about right? I have four 40% planes, a Piper J-3, J-4E, a Stinson 108-3, and a VANS RV-6. Also have a 30% scale Stinson SR-10, that is almost as big. The SR-10 and the J4-E are powered by Fox 5.8 engines, with 27 x 10 mejzlik props. Plenty of power - weight about 45 lbs. The Stinson 108-3 is new, and will use a BME 115 with a 28 x 10 Xoar prop. It is still being worked on. The VANs has a GT-80, but that made it quite nose-heavy, so I am thinking of replacing that engine with a lighter one. The J-3 uses a DA-100 with a 27 x 10 Mejzlik prop, and it is just right for the airplane.

For servos, I mostly use Futaba heavy duty 1/4 scale. They are limited to 5.8 volts - that is the only downfall that I can see with them. They are relatively cheap. Never had a problem with any one of them.

For batteries I use A123, 2300 mah running through a dual Max Prod. ACC-135 regulated to 5.5 volts. Two batteries on the receiver, and one on the ignition. These are designed to be removed from the planes for charging - much like an electric. I use a FMA - 4 charger designed for 123 cells, and after an hour of flying, they can be recharged - one at a time - five minutes each. Six packs run two airplanes. They do not have a memory, and can be charged a 1000 times. Also said to last for at least ten years. These are charged from my truck, and can easily be charged at the field if need be.

If I can help you with anything else to make your project easier for you - fire away. I'll keep track of this thread.

Status: offline 		Understand on the engine choice, in the picture of my 141 Briggs engine is a nicely balanced steel weight, it will go on top of a prop and was on a spitfire years ago. Keep me posted on your CG in the end. Tri pacer also has a pretty short spinner as shown in the Wag aero picture. Believe a salvaged pacer spinner could be cut down for that perfect look.

I purchased one at a swap meet and it is really grungy.
Bought it from someone I know so I know the engine runs well but it looks like heck.
I know that this is off the mainline of the thread. You can PM me or whatever,
Thanks, Ron

No matter how long it takes, please keep this thread going.
Does your girlfriend know you use her tooth brush? If so, I hope it is one she has discarded.

Status: offline 		Okay. Got it. A funny thing happened just this morning while having coffee with my girlfriend. She said (as she has many times) that my writing on line is AWFUL!. No punctuation. I know. I'm not a typist, but I can do better, and will. Sorry. And by the way - - she's a writer. Oh, and that's why I use HER toothbrush, because she scolds me, but she hasn't figured that out yet. Ha. Ha. Okay. Seriously, I use the toothbrush in-between cooling fins and hard to reach places. That stuff works great, but a lot of black comes off, so you'll need rags.

Yea, this project was planned to be started with the first snowfall.
I've been gathering materials since the beginning of the year. I am undecided on wing strut material - - - aluminum, or wood? I decided on an all wood cowling instead of making a fiberglass one. A fiberglass one may be down the road.

For years, I loved Cessna Aircraft. One day, while at an airport in Tok, Alaska, where I had been living for 6 years, on a beautiful winter day, I saw a Piper Tripacer for the first time - and thought, Wow, - what a beautifully shaped aircraft. To me, they are simple, classic, sturdy, and truly pleasing in appearance. So, there began my love affair with this little airplane. At the time, I was building a Bud Nosen trainer, with a 102- inch span, with 4 ft. floats, - and a Maloney 1.25 . . . . a beautifully designed engine. At that time, I decided it was a good time to take a break from all the building. I was busy in the Air Force, stationed in Alaska, and loving the outdoors and the frontier wilderness. Saw a lot of wildlife and Piper bush planes, too. I was an Aircraft Maintenance Specialist, - so I was never far from aircraft. They were just a whole lot bigger. I was also building a Pica Cessna 185 - with fiberglass fuselage. What a great kit that was.

Nothing new on the model to report. Looking forward to Thursday and Friday, my day's off, to be back in the shop.
