A catalogue of contradictions !!!!
I've had to put 390g, approx 3/4 lb in the nose to achieve the balance point at the front of the joiner.
Sebart gives the weight of the plane and the weight of a battery, but it won't balance without the additional nose weight.
Sebart says fly with a 4500 to 5000 6s.
Dealer website says fly with a 5800 6s.
Instructions with the model say :
6s setup 5800 6s.
8s setup 5800 6s as well !!!!

Sebart says use 3 standard servos plus 2 minis for the elevator halves but you would have a heavy servo for rudder and a lot of cutting out to do, possibly not leaving much for a standard servo to screw onto.
Dealer website suggests some servos, but they are smaller than the holes in the plane !!

The overall weight of the plane comes in at about 9.5 lbs 4.4kg.

Motor choice, I chose a Dualsky motor with about the same performance as the recommended Hacker A50 16s with a 16 x 12 or 17 x 10 prop.
Hacker website says this motor is 1200 Watts for 15 seconds and max power is on the 16 x 12 at 1590 Watts...similar to the Dualsky.
On a fully charged battery you get 167 Watts / lb.....however towards the end of the flight as the voltage drops towards storage charge levels you are down to about 119 Watts / lb....little more than a trainer performance and certainly not enough for big smooth uplines with the drag of a roll on the way up if you put one in.
So I've had to order a more powerful motor and wasted money on a motor of similar performance to the recommended Hacker A50 16s.

In conclusion, the model looks great, and I hope it will fly beautifully, but the info from Sebart is a catalogue of contradictions, misleading information and poor advice.....phew !!!!
I hope all this will be forgotten once I fly her.
