G'day luke... 30% is small these days... just like my Alpine 2channel amp bridged for 340W RMS LOL!
Its a 42% scale Extra 330.
157cc twin cylinder petrol motor (approx 20 hp), has electornic ignition system. I am looking at upgrading to a 170cc, 210 cc is starting to get around these days as well!
Requires 10 to 12 servos that are capable of 25kg/cm of torque.
You need a very robust electircal system to run these things. I have about 10 amp hours at 8 volts on board!!
On board redundant power distribution system incorporating a voltage regulator, the equpiment runs on 6 volts hence the need for regulator. The system can experience spikes in current draw of up 25 or 30 amps when doing hard manouvering.
Then there is the advancement in radio technology!! We have moved into spread spectrum radios, computer controlled and completely programmable transmitters, here is pictur eof the transmitter I use....... 2500 bucks right there alone!
