Rummy's Savage E-5SC

[NickRummy]

Well the test run was disappointing..... Truck is still in one piece so I can't complain too much.

And some data even though it's pointless...



What do you guys think? ESC Failure? I sure hope it's not the motor! Why are the "max" ratings on the data logging really strange? 75k RPM!?

I sure hope it's not the motor. Those 1717 motors aren't exactly everywhere. 75,000rpm????? Highly unlikely but who knows. Did you take the motor out and try to turn it by hand? Should also take the front of the motor off and have a look at the state of the rotor.

IMO the slipper on the Savage is way too ineffective even on a normal Flux. Same thing as you have found out. Either it screams in agony slipping or you have to lock it to the point where you might as well not have one. Have a look at the slipper eliminator from Alza racing.

Edit; Just had a closer look at the graph. It states (to me at least) that it is the readout for a 2 pole motor. The 1717 is a 4 pole (ahhhh duhh). Anyway that 75,000rpm can be halved. I think you only hit 35-37K. I hope I am correct here.

When I was tightening the slipper I noticed the pinion was loose as well so I tightened that. The motor still spun freely, you could feel resistance every time it spun past a magnet like it should.

Looks like you are safe then. Is the problem still there? If it is then the ESC might be toast. Is it a recalled/fixed unit?

[NickRummy]

Yeh its a recalled XL. I guess I just wait for the XL that I currently have at Castle to be replaced and give it a try then.

FINALLY! A working speed control! Hoping to have test runs tomorrow.

Is this the boat or the car version? The car is 16S 200A.

Did you pick up a programmer too?

I think this might be his V2 but yeh, it's the car version. It says 150A on the bottom of the ESC and it says 3S-17S too. I got the USB link from him and a turnigy BEC as well. I downloaded the software to program it but haven't had a chance to bring the truck in to sit it on my desk. You need the motor hooked up to hear chimes while programming.

It is a car version and 200amp. Fighter Cat Brandon ran out of 200amp stickers and used 150amp stickers. Both versions can handle 17s, but he markets the car version as 16s for some head room.

Have you tested the Fightercat yet?

[rckcrwlr]

funny thing is I was going to order one and that same day I got my notification that CC shipped my XL2.

Be careful on your first run, don't gear it too high. Check out this thread. These esc's may not be as good as we hoped.
