Here are more pictures . This is my Epsilon ARC. Last weekend was their Maiden Flight. The configuration that I used was:

OS 91 FX
APC 14x8

Fuel Tank in the CG (20 oz.)
VT-30 Perry Pump

Futaba S9101 for Ch 1 & 6
Hitec HS-5945MG for Ch 2
Futaba S3004 for Ch 3
Hitec HS-5945MG for Ch 4
Futaba R127DF
Futaba WCII

MK Bell Crank for Ch 2
Pull – Pull for Ch 4.

CG: +/- 40%.
Weight: 4.550 Kg.
Fuel: Dynamix 15% Nitro 18% Oil (http://www.dino.com.ar/productos/dynamix/dynamix.html).

The first two flights was with the engine incidence too low and to the left. Use the cowling as guide (for the OS 91 FX) and you can’t go wrong.
I defined three conditions: 3D as Marcelo says for 3D, Normal as Marcelo says for Sport and Landing with 40- 50 % of Sport definition. Exp –40% for all.

On the fourth flight I increased Ch 4 in 10-15 % for conditions Normal and Landing. For Pattern Flying I used Landing condition but I still think that I must decrease Ch 2 in 5-10%.

I increased Ch 2 & 4 in 15% for 3D and I can do hovers with 50% of power. At 65% I have unlimited verticals.

I tested the WB 60 six months ago and I really liked it, but after 5 flights I feel better with my Epsilon. I selected it for Pattern AND 3D !!!.

One incredible thing with the Epsilon is the Knife-edge and the Snap Roll !!!

P.D: GRACIAS a TODOS en CAModel ...
