R/C Tortoise is a very simple r/c
tortoise "bot" with direct control,
using a 4 channel radio system.
It uses 4 sub micro servos, and each
axis of the transmitter stick controls a servo.
Tranmistter & receiver. 4 (or
channel ground legal radio transmitter and receiver. I am using a Spektrum
DX7 radio, but a
DX6i,or cheaper eflite
5 ch 2.4ghz radio would be
ground legal as well. If you do not get
a complete system, you'd need a 2.4ghz spektrum
reciever as well.
