Darren, I used Goop on an Iowa hull and it was great, kind of similar (I think). It also reduces noise like you say Beaver, I will be using a Clippard hose clamp on the motor side, it's already pretty tight. The 1/8" propshaft is much smaller than the 4mm motor shaft, and so I need the clamping power of a collar with a setscrew.
Tugboat, I was just wondering if you ever saw these. http://www.hobbyking.com/hobbyking/...t_Coupling_for_Boat_23mm_x_3_17_4mm_2pc_.html They might work well for your application.
They look very cool, and no I hadn't seen them! But I am sticking with the hose for now. It's even cheaper, and it's quiet as heck. Future boats may well find some of those fancy metal ones installed...
I wouldn't know which is better. I have the nylon ones in this Suffren I bought. I imagine the steel ones hold up well until they rust or need oil. Unless they're nickel? Maybe just need oil. If they spin at the right speed, I would imagine that any extra weight incurred would help with torque. That's usually true of flywheels and other weights on driveshafts.

ahh, but this has 4 nubs on each side, plus it is slef lubricating meaning a little slicker in the joint (I am channeling my inner shaft, can you dig it)
Collars arrived a day early! Nice surprise, and it means that I can test the driveline tomorrow!! I've got the electric heater preheating the shop so it's not totally frozen when I go out in the AM... The gas heater will get it toasty warm in no time.
Here's a shot of testing the collars today... Works very well, very quiet. All set for hunting wabbits...
It says right on top of the motor in the PIC above your post. http://www.hobbyking.com/hobbyking/store/__16233__NTM_Prop_Drive_35_42_Series_1000KV_700W.html
thanks chase, I'm not crazy About the Brushless motor, only because each one needs there own speed controller!! Nikki
Two brushless motors and two ESCs for them are cheaper than two $5 550-sized brushed motors and a single brushed-type ESC to run them. By a wide margin.
I'm not sure that comparing hobbyking escs to mtroniks is a very level comparison. Also... I can get a 40A Mtroniks Viper for 65, add in the two cans to make 75. The two HK ESCs will run 20 apiece for 40, plus 20 a piece on the motors, makes 80.
