Lehner Rivercat build

Looking great Travis. That motor is going to make it a rocket, beauty job on the connectors. How does 1850 kv loaded translate to the unloaded kv that all the others use?

Thanks man. I was worried that having the rear of the motor up like that, I wouldn't be able to come up with a nice solution on the connectors. I think it turned out nice too. I'm hoping this thing is as fast as mine or faster. Im not sure on loaded vs unloaded thing but these motors are supposed to be pretty strong. If this thing is rated at 1850kv loaded....it's going to be a rocket!

Flipped it over and epoxy the bottom of the stuffing tube. Can't do anything else until this cures....so not much progress. Once I get back to the top side it ought to go pretty quickly.

Back on this thing. I've been working on it, just haven't posted. Got the strut/rudder assy mounted. Stuffing tube done. And I just made the servo mount and epoxied it in.

I'm liking these servo arms your coming up with on your builds !

I knew someone would like that. Check this one out...

Lehner's from what I've "read" are roughly 11-12% less than unloaded. So 1850kv loaded is around 2050kv unloaded.

Esc mount...




And finished

Been pecking away at this. Just haven't been posting. Got the battery trays done.





I machined the strut to accept sealed ball bearing. I've been doing this in all my latest builds. No water up the flex. No slack. Less friction. Win win I guess!

Looking fantastic, the slots for the battery trays are a much needed improvement over the ones you can buy. Have you been playing with your cnc lately?

Not yet, I set it up in my shop but been too busy to fool with it. I did buy cut 2d program for it.

I guess the cnc would make a better winter project. To many (more) hours stuck inside when the weathers nice.

Nice work, what size bearing do you use?

1/8 thick. R156 is the number. You must use 5 or 6 of them stacked. If you use just two, expect a very very short life.

This is very true. I'm in build mode and running mode right now. I'm making trips to the lake several times a week. Sometimes 2-3 times a day. Trying to line out boats. Lost a test prop on my Rivercat yesterday. That prop was awesome too. The boat was stable, no torque roll. It had a closer take in the blades so the thrust cone was tighter. At about 65% throttle it went 71 on 5s. I could not give it full throttle because the wind was blowing very hard and the water was very rough. So that was tooling around and taking it easy. Then the prop nut came off. First time I had that happen (from what I can remember) and lost this prop. Pretty bummed. The boat just sounded so smooth. The m645 sounds like it's beating the water compared to it.....it just sounds so smooth. O well. I ordered a couple more.

Awesome thanks, I found some at a local hobby suppliers :)
