Lama V3



Tiny and funny. I learn some orientation (Backwards, funnel..) with this.
Latest modified with a 6m long copper enamel wire to provide unlimited power from a PSU. Much cooler as reduced payload.

F16 EDF




Bought from Shinjuku, Tokyo 2006.

No yet fly this as I intended to modified it to 3 channel.

MP5




My first MP5 electric airsoft gun.

T34 Mentor



The first plane that I really can fly. Gear box with motor 300H. I flied this with my kids , and a trainer cord.
The plane is pretty stable depite its low wing config.

Unable to get spare parts and was converted to brushless motor and my first DIY motor mount.
Retired when uncontrollable roll depsite numerous repair.

Flying team June-2007




Too many raining days. Do happy with the performance of A123 Li-Fe cells.

$1 Voltage regulator for digital Servo

Align stock 5.1V regulator to drop 0.7V out of the 6V BEC is
M4N RL201 2A diode

You can buy a 3A diode 1N5401, which is slightly larger. 1N4001 is 1A version and smaller. It is good enough for a single digital servo like Futaba 9254.

I cannot find 2A version in my proximity.
