Old friend.

There could well be still in existance, and even still flying & working, airplanes that I personaly saw, flying & working, as a high-school student, 60 years ago, but the only two I know of, for sure, is the lovely lady you have so kindly posted, Hawaii Mars, and her sister, Philipine Mars! Many thanks.
As an Air Scout, I had a gate-pass for Alameda Naval air station, the home port & eastern terminus for the Mars boat's trans-Pacific runs. I spent many a summer day on the recreation float, near the Mars's mooring point, so got to see all 8 flying boats, at one time or another.

I'm glad you enjoyed these pics. how cool that you saw these beautiful planes so long ago. It was quite a sight to see those 4 engines come to life and this big seaplane take off

Hm?? All eight boats? I must assume that you mean the Clippers, as there were only five Mars built. Aaaand I don't think the Mars ever flew commercially, other than water bombers. That, of course, doesn't mean that I don't envy your contact with these aircraft! I saw the last flight of a Stranraer, and there is no way I could or would ever exchange that experience.

I am fascinated by flying boats; float planes, not so much. I have the Cleveland plans and templates for the Martin M130 Clipper, and just recently was given enough balsa to start construction. I do believe that the plan was to generate a non-flying (display) model, but I can't do that. The balsa was free, but now I'm faced with powering the thing! I am looking at direct drive 600s and commensurate controllers and batteries, but I think they will cost more than most cars that I have bought in my life...

My hands are steady enough to be the envy of surgeons half my age, but the brain, I'm not so sure! No idea why I said 8 boats. Thanks for the history, anyway.
Despite documenation that says to the contrary, I know I saw a Martin M-130, parked on beaching gear, with the U.S. flag on the side, at Alameda, in 1948. (I remember saying to the other Scouts, "Hey look, there's the China Clipper!").
All the Mars flying boats I saw in those days were very much in the U.S. Navy, with overall "Deep-sea" blue finish, and Stars & Bars. Although the Pacific War had been over for 3 years, there was still a lot of hauling to do!

Hi mate how you doing DD S600s are going to be heavy and power hungry and will go off pretty quick..... better to go with a geared set up ... take a look at I van Pettigrew's more recent offerings S480s or geared buggies or even S550/600s - whats the size of the model?

If they are brushed motors you can run 4 geared brushed motors off one HD controller or a pair............ thats not going to break the bank or cause headaches.

Doing well for an old blighter, thanks for asking!

The Cleveland plan is 8' span, and Scale. That means that I have very limited room for props, probably 9" max, 3-bladers for scale effect. Gearing would be fine for larger props, but I considered a small reduction to use the most efficient motors I can find! It doesn't matter much what I do, this will not be a simple project, and power/weight/drag is going to be a real balancing act.

Try as I might, I cannot pass up this challenge. If it works, it will be my very best achievement in my 60+ years of model building and flying...

I went back out to Lake Elsinore today to try to get some pics of the martin mars taking off from the other side of the lake. For some reason she did not fly today. I went to the other side of the lake, because the plane takes off about 200 yards off that shore line. spent about 4 hours waiting but no luck. I might try tomorrow....
