SU 37 Terminator Miniprop


I bought this EPP kit from Staufenbiel in Germany. 40.
http://www.modellhobby.de/MINIPROP-S...rodNr=232F7160
The kit contains EPP pieces and some hardware.
You need to buy motor, esc, servo's, receiver and battery.
This is my first vector jet.
Pieces are well cut and fits nicely.
Building as usual from EPP and inserted carbon strips and rods glued with Cyano.
I used big square hardwood blocs as templates and weight to ensure flatness and squareness.

Motor: Turnigy D2822/14 Brushless Outrunner 1450kv ,48 grs with backplate and propmount
Esc: 25A turnigy
Servo's:HXT 900 9 grs servos
Battery: 3s 800 mah
12 A full throttle => 144 w
Ready to fly: 379 grs all inclusive.
Balance: 47 cm back from the nose tip
Ailerons and elevator throws : 20 up and down.

Seems me possible to save 5 grs on receiver, 10 grs on esc and wiring.. not more.
6 grs servo's seems me too weak (gears mainly)
I maidened with a 8 x 4.3 but current prop is a 7 x 4.
Consumption on the 8 x 4.3 was too high at 17 A. The 7 x 4 drops consumption at 12 A thus perfect for this motor and reduces torque effects.

First flight revealed impossible to turn to the right! I adjusted side trust to the right and inserted a small 6 grs weight in the right wing tip!
My mistake was a motor mount slightly glued with a left side trust, maybe one degree but in addition with the torque was a big hint!
Flies now great, I did already 10 packs with great pleasure! I even manage cobra's !
It's already very reactive as this and I will increase step by step the throws Beware with elevator as with the vector system 20 is already "a lot"
Since then, I rounded the leading edges and I feel the difference in the top speed!
