Small 3D helicopters

3D helis - detail

Started flying 3D with Blade Nano, Blade MCPX bl, and Trex 150. Stepped up to Align Trex 450 plus DFC, an Align Trex 450 Dominator and an Align Trex 550L Dominator.

Learning to fly

I have followed the method described on the Helifreak Forum by Archmachau:

From tail-in to all 8s and funnels in 6 months

Modifications

Modified Trex150 and MCPX bl with longer tails, other canopies, better landing gears, other blades. Modified Trex 450 and 550 with Align speed canopies, Align Gpro controllers and Castle Creations Edge ESC with data logging. To find the small helicopters during practice in long grass I added a small homemade timer PCB (6 grams)  with a buzzer. This lost and find aid gives an alarm 6 minutes after powering the helicopter.
