- FlyDream have made a great impact with their 2.4 GHz radio conversion modules and receivers. The success of this low-cost conversion has made a great reputation for FlyDream.
Now FlyDream have released a range of super-micro servos that are ideal for sports use - for indoor and park flying. The 2.5g is as good as you would want for indoor, and the 4.3g is a worthy substitute for the D47 where power is not a great issue. If you want maximum power in a tiny servo (for pylon race or for thin wings and tails in a high performance aircraft) use the Dymond D47, but for sports use the FD43 is ideal - it is just as light, just as fast, but with less grunt than the D47 for one third of the price.
All servos available with JR/Hitec plugs - 2.5g servo also available with Micro connectors for the 1g Rx.

Please note that these servos were tested with an Emeter 2 - the dead band indicates the sensitivity of the servo. In other words, how much you have to move the Tx stick before the servo responds. Some cheap servos have unacceptable dead bands - you can see the control surfaces on your aircraft moving in a jerky fashion. These FlyDream servos are significantly better than other low-cost servos that have been tested. Try them - you will be pleasantly surprised.
For comparison sake, the D47 has 1.2 kg/cm thrust and a dead band of 6-7 micro seconds. The FlyDream 4.3g servo compares favourably in size, weight and dead band but with less power.
Price for all servos: $12 each
