Spinner motors

[epicentre]

Most ants that use 12v (12.6v if you want to be accurate, 3 x Lithium polymer cells) are spinners, and as such have a ESC for the weapon motor, this normally has a voltage regulator onboard, which you then use to power your reciever and drive servos. If you want to run more than about 6v in an ant without an ESC, then you simply take 2 lines off the battery, one of which goes directly to whatever it is youre running at the higher voltage, the other of which goes through a 5/6v regulator to the RX and other servos.

I see

Some servos can supposeldy take it, usually the larger ones. The micro servos get upset above 6V really. Some have had success at 7.2V. It all seems a bit hit and miss really, but yes, the rest of the ant is run off the BEC

Eddy that sounds like a good idea. I have a static prop balancer which has been good enough up to now (max 35000 rpm) but if I do get vibration problems I might just look into that.

yay my stinger arrived today

nice pic of it sitting on the new ant (wheels are just there to give and impression)

Having said that, model gas turbines are usually statically balanced, and they run up to about 160,000rpm, so it works, with a little bit of patience. Just a thought

what do most people use to connect there spinner weapons to there motors? I was thinking of just placing the(thin undercutter)blade directly on the motor.Mainly to save space& up the rpms

[epicentre]

Most antweight spinners have the disk/blade mounted directly onto the motor output shaft, the only exceptions I can think of are Pixiedust, a FBS that uses a small gearbox to up the torque, Duff (I think) who again has a small gearbox, and Zenith (mine) who uses a 3:1 belt reduction using pulleys and belts from old cd-rom drives.

and DBA(a.k.a. KillSaw) which uses a 1:3 gear reduction

*slaps forehead* How could I forget DBA My apologies, Tim.
