Help, 1527 1Y vs 1717 1Y

[RaceMechaniX]

Very few motors will run well at their rated RPM. It is mostly a marketing exercise and a reasonable safe limit. The 1527 has better rotor construction for higher RPM, but on 6S both are good choices. From my own experience the 1527 motors are very safe under 45k, but risks increase if you go above those RPMs. The 1717 is good below 35k RPM.

The torque output of both is very similar and both have pretty good construction.

How many cells do you plan on running? In general my nod goes to the 1527 for SAW use.

BTW, I have run a 1527 near the 60K RPM mark for a SAW rigger and it is a razors edge in balance of very high currents and prop load.

Are you planning on trying for a record Cooper or just for personal use?

Depends how testing goes :) For personal use, but I would like to get into the hunt.

6,8, and 10s. Castle ice hv's. Yes saw only. I just wasn't sure about running in the low 50k rpm range. I always log and always want to be pushing the limit.
Thanks guys for the information.

Stick with the Neu 1527.

Well that's got me my decision. One question if anyone out there has done it, what cord or test (Kevlar) have you used to rewrap the rotor?

[keithbradley]

What's the setup Cooper? You don't have to be specific like kv...just what size hull and single or twin?

[Cooper]

Twin fantasim, cc ice 200hv's. I just am getting started. Have hull, stingers, have to get motors, speedos,,,, well got 1520 serius motors commin, :) also but I'm also getting some neu 1527, be able to play with both as I'm probably going to need more, hope not but always prepare for the oops moment, or I guess that was too much. Lol.

Any chance of a "build" thread for us to follow?

Rotors should be wrapped with Carbon NOT Kevlar. Kevlar is like nylon, it stretches that is how it stops bullets.
HP Motor builders found that out over a decade ago.

Good to know for future use. I had several tp motors fail from magnets comming loose. (a little high on amperage = heat build up) yes was pushing them but oh what fun it is to walk that fine line and get away with it. :)

Yes build thread to come. I am currently finishing up a rescue tug build. I may start work on the hull soon. I usually like to have a good bit of work done before I start a thread, but I'll get some stuff around and get her up and running. Look for a build thread titled MAD CAT or ANGRY CAT
