This was the Full Ready to Run (RTR) version, just add receiver batteries, stickers and off to the local pond! The tested boat had a 775 electric, 12cell motor. I ran this boat on 12- 3300 NiMH Batteries. It will run for 6 to 10  minutes with these batteries. After adjusting the outdrive it was able to reaching speeds of 16-18mph. Max speed was verified on a Garmin Etrex GPS. This boat carved the turns!

Update 11/29/04 The new Grey Thunder comes with a better esc boosting the speed up to 18-20mph. The video shown is still the old esc.
