One day I was trying to fly my radian glider around the Holdfast Model Aero Club in circuits with the other power planes. A nice chap named Ashley gave me a test fly of his electric ‘Thunder Tiger Trainer’ which could automagically keep it’s wings level with the horizon (using a fancy sensor or three). I decided I would try to build something similar. I did, and the result was awesome – a sturdy, reliable trainer that has flown hundreds of times and has not had a single repair! I have replaced the 4260 AeroDrive motor which I needed for another model with a G60 and moved the elevator servo to the tail to get rid of the long pushrod.
60 Size Thunder Tiger Trainer:
I jumped on the HobbyKing website and ordered:
- 13/4/2011 Turnigy 5000mAh 6S 20C Lipo Pack (AUS Warehouse)
- 1/4 /2011 H-King 60A Brushless Speed Controller – Helicopter & Fixed Wing
- 1/4 /2011 TGY AerodriveXp SK Series 42-60 500Kv / 1475W
- 1/4 /2011 APC style propeller 12×6-E
- 1/4 /2011 PolyMax 3.5mm Gold Connectors 10 PAIRS (20PC)
- 1/4 /2011 EC3 plugs (10pairs/set)
Then I started scouring the web for a ‘Thunder Tiger 60’ model – to no avail. So I started wandering around the local hobby shops and when I got to ‘Model Mania’ in Morphett Vale I found one that had just been bought in on consignment. $130 later I had my plane!
