2 Graupner Key Biscaynes

Ron's entry in the wonderful world of RC boating. After several changes it's still going strong, and a speed of 47,9 km/h has been reached.

Motor: Graupner speed 700 neodym Speed Controller: Protech pro 40 Batteries: 2x 8 cells 3000mah by Sanyo Prop: 39 triple blade by Graupner Hopup's: Gundert watercooling

Starting with a standard 700, it's now powered by a 700 neodym; the original 12 cells have first been upgraded to 14 and recently to 16 cells. Thanks to the special Gundert water cooling the motor temperature stays within acceptable limits, even on this number of cells.
The speed reached using 16 cells has not been measured yet; did we reach 50 km/h... ? I hope so!

Key Biscayne (12 years and still going strong)
This is the key biscayne which is 12 years old now.
This has seen a lot of running time and a lot of rebuilds to the drive system.
It started when i wanted a faster boat after trying to get a robbe unlimited (the first version) a bit faster which didn't succeed very well.
Then the Key Biscayne came in the first runs were done with a white hull and the ice still on the (big) lake were we ran.

The first setup was the original with 12 cells and the stock 700 motor, also a mechanical speed control was used but this was burnt on the second run (how could i know beginner, el cheapo) and a electronic speed control and 14 cells were put in.
After a few months 16 cells and watercooling to the motor were added and some other mods were done.
A year later a robbe 420 sports was found and this was the ticket to a lot of fun and speed it runs about 50 Kph now but for 8 minutes on a 2000 ma pack of 16 cells.
This setup has been in for the last years but i am planning a mayor rebuild this summer so come back for the updates on this project...
