I appreciate your kind words, on a tight budget you almost have no choice, LOL!

Thank you, I will give a full report, and try to take some snap shots.

I think the only thing left is to install some rubber on the knees and perhaps a few tire fenders.

Excellent work on your Springer! Your Captain reminds me of a model the late Bill Noonan did of a pre-war Messershmitt passenger plane. He had a pilot with a cigarette hanging out of the corner of his mouth, and a sign on the back wall of the cockpit stating "Fumar Verboten."

Your model stand caused me to make a mental note that when cutting out the sides of a Springer, the bottom pieces should be saved, as they will fit the hull perfectly as part of a boat stand. I look forward to seeing it on the water.

Thanks Pete G.
I had the chance to try out my springer in a buddies pool, before going out on a pond or lake, just to be safe and avoid a swim.LOL!

She runs great, better than I ever expected.

Hi All,

Have read most of this very extensive thread and got the springer bug along with lots of good ideas. Have 3 grand children who will be potential springer drivers. Started construction on 2 springers (read that 2 is the minimum build) Am using gorilla glue as it says it is "100% waterproof" We will see.

Am thinking of a removable top deck that will allow complete access to the hull. Need to come up with ideas for a gasket to waterproof the hull to deck joint. Here are a couple of pics of the construction progress so far.

Find running gear yet?I had gotten a 1/2a running gear set from dumas along with the dogbone set.Used an electric drill motor for power and some of my rc car 7.4 batteries for power.There are some $10 esc's on Ebay that work real well (320amp)got five of those cuz they were cheap but they did take some time to come from china.You can find one of my boats pushing pumpkins in the Dock talk area under (pumpkin regatta)Its the creepy pumpkin head.Cut a 2x2 piece of aluminum for the rudder soldering 1/8" rod to or sand 1/2 flat then drill two small holes to put in some screws.Overall these are so fun to build,did one in a week from start to finish.If you have any questions just ask

Have a Mtronics tio Marine 15 ESC I plan to use. Have several brushed motors from earlier times to select from. Some are listed here:

Kyosho Magnetic Mayhem #70672 22 turns
Kyosho Atomic Force #70567 17 turns
Kyosho EndoPlasma #70566 16 turns
Graupner Speed 400 6v
Graupner Speed 600 9.6v
Graupner Speed 700 Turbo 9.6v
Graupner Jumbo 2000F Best.-Nr. 1770 12v (Has 5:1 Gearbox)
AstroFlight Cobalt 05 (I have a Gearbox for this one somewhere)

Also have a Master Airscrew gearbox for the Kyosho motors if needed. Have a 1.5 inch 3 blade prop but could go up to 1.75 inch prop.
Anybody have a sweet combination in a Springer using one of these motors?

I think that your Kyosho motors are too fast. They overheat immediately and expend your battery.

JPCAT: Thanks for your suggestion, I will select from the other motors.

Also found a surplus motor I bought some time back that has the following label.

JUNDI RS555-2580 DC 24V

It may be a 55 turn motor like/similar to those mentioned in this thread and may work direct drive as others have said here.
Plan to make the motor mounting plate accept as many different motors as possible and do some testing in the water.
Voltage not to exceed 12v (ESC) and may be Lipo 3S as I have some of these for my planes.

If you aim for a no load shaft speed of around 6-8000 rpm then your in the ball park, so any of those motors could work with a gearbox with a ratio that gives that shaft speed

I will recommend 540 motor of 50-60T by 7.2V. It is 6-8000 rpm. If there is no resistance in the drive system, it is not necessary to cool the motor.

I have had no problems with the drill motors that I use.None of them have ever overheated in the two years Ive been using them.I have run them on both LIPO or 7.4 NIMH battery pack,both have 1.5 dumas props because they are spec boats for water polo.
