Feigao 540C

I"m ready to order my motor and ESC and had a question about the 540Cs. Do they have the same end bell problem as the smooth cans? If so is there a fix? Would the Wanderer 9XL be a comparable switch and does it have the same end bell problem as the Feigaos? What's the ETA on the smooth can 8XLs? I'll be running a MM ESC on 14 cells.

I'd like to go ahead and put a combo together and get my Revo on the track, but those smooth can 8XLs seem to be scarce. I'd like to use a smooth can 8XL with RCM heatsink/clamp, but would be willing to try something that's in stock that gets close and is about the same price.

Thanks,
Cajun
