What happened to Brushed ESCs?


I wanted to make a HZ super cub from parts, and wanted to keep it with the stock brushed motor. So i was looking around for a 20-30 amp brushed ESC, but i found very few that were actually in stock. i found this from hobbyking.

http://www.hobbyking.com/hobbycity/s...USHED_ESC.html

but is there any place i can get one in the states for a reasonable price (~$10-15)? it seems like all there is is just brushless stuff, but i want to keep the super cub as close to stock as possible. THanks

BPHobbies has a few. The Blue Arrow BA-PP-15C and GWS ICS-400Li are suitable for 3S Lipo.

I don't recommend the GWS ICS480Li, as it will probably burn out and crash your model!

Tower Hobbies has the Great Planes Electrifly Series; 7, 12, 25, 35 and 55 all with BECs and Li-Po ready with this statement:

Low Voltage Cutoff: 0.80V per cell for NiCd/NiMH
2.75V per cell for LiPo

Easy to find. Just do a search on Tower Hobbies for brushed ESC

Here's an example:

Some HK brushed ESC are OK with lipo. The vast majority of them will work but the LVC is poor. Read the specs-GWS is awful, electrifly is poor, and even Castle ain't good at all.

You shouldn't fly to cutoff anyway. It's not good for the battery, and you risk not having enough maneuverability to make a good landing. Better to time your flights and come in with plenty to spare. Treat the LVC as an emergency device that prevents loss of radio control if something goes wrong (eg. you forgot to charge the battery).

Some of my models still have old controllers that don't do Lipo cutoff. I just make sure the battery is fully charged before each flight, and have a countdown timer linked to the throttle.

The Turnigy 30A brushed ESC (AKA Hobbywing Eagle) is OK, but I have seen a few of them fail due to the brake FET shorting out. Disabling the brake may improve reliability!

I don't have a solid reason, but I guess I just want to keep it as original as possible. In fact I'm thinking of just getting an rtf or bnf super cub.

Good answer I had not thought of it from the classic / collectible perspective.

Let us know how the HK brushed ESC perform.
