Ko Vfs 2000

KO is a good brand, the advantage of the VFS 2000 is that the drive frequency is adjustable for a specific range, unlike other speedo's, you can adjust the drive frequency but it will cover the entire range.

Looks good, performs well. I have never had a problem with mine!

Got mine from HOBBYMANIA for a good price, never used the hyperbooster but would be interested to hear from anyone who has.
