About a month ago I decided to build a trainer, but a bigger then usual trainer, well for myself that is.
I started of with my desired dimensions
I wanted at least a 40 inch wingspan, and I wanted it to be able to carry a bit of a load. Another requirement was a low amp power system that would ensure a longer than usual flight time.
I then started to order the parts from HobbyKing
Motor
hexTronik DT750 Brushless Outrunner 750kv
ESC
TURNIGY Plush 30amp Speed Controller
Prop
10 x 4.7 SF Prop
Servos
HobbyKing 929MG Metal Gear Servo 2.2kg/ 12.5g/ 0.10sec
&
HXT900 9g / 1.6kg / .12sec Micro Servo
The rest of the parts I had as spares lying around doing nothing.
I then gathered all the foam I would use and I started building.
After about 18 hours she was finished and I ended up with my new big trainer with a 47 inch wingspan.
I placed a 450 size heli canopy to give you an idea of the size.
I then decided to add some LED lights for some night flight fun
I took it out the next day for the maiden, and was very happy to see it fly the first time without any major problems.
i did a test to time the flight time on a 2200mah Lipo, and the battery lasted long past 20 minutes.
As a whole I am very happy with this build, and I will post some nigtht flight videos soon.
Happy Flying :)
