I ordered this ARC model in the middle of 2005 from Turkey and got it 3 month later as thy promise me.
I finish it and fly it on April 2006 with my old OS140RX (I have 2).
After 10 flights a decided to fly my old desafio2000 at the 4th open in Cyprus only 2 weeks later.

Than after I came back from Cyprus I install the new OS in the Impulse and make the break-in. when I finish all break-in process I took the Impulse in to the sky.
That was the last takeoff for that model. It crashed after one of the stabilizers got away.[]
It was my fault!!![:@]

I didn’t do double check for every part of the model after break it in.

Any how I still made 10 full flight, I can say it was light, my models was 4,460Kg
The engine was more than enough power, as much as I remember I didn’t use any mix to have good knife edge.

I also used MK control horns and Clevis, central hobbies CF pushrod.
Servos was JR 8411DS for elevator and rudder, JR 9411SA for ailerons and JR 331 for throttle.

If you need some details let me know and I will try to help you

I attached some photos of my Impulse from it first day I got it to the last day.
