The Overdrive is a great flier, looks very cool on the pad with that unique fin configuration and will do very well on anything from 1/4 A to the A10-3T. Just keep an eye out as it will go pretty high; fortunately, the red streamer makes it easier to track.
My son flew his a bunch at NARAM45 this year...so go have some fun!
It's a matter of trying to keep things as upto date as possible. Information on the web is (in most cases) more accurate and up to date than paper documentation.
The A10-3 works great on the Overdrive. The only possible concern (minor) is that the 3 second delay is a *little* too short, but then the Overdrive is going so fast/high on the A10, that you'll never actually SEE that problem...
Other motor updates that won't be seen in the paper documentation for a bit:
Triple Threat now uses the A10-3T as a recommended motor and as soon as I can get the pages updated, the Richter Recker now recommends the E9-6 motor.
