*DETAILS* PLEASE READ*. (Due to a previous crash, NitroPlanes fixed this model, before it went on the market.) I like this Reaper, although it has a weak aluminum wing spar that caused me to fold the wings ending with a bad crash a couple of years ago. It was time consuming to setup the control cables and wing flaps as the wings are very thin.. It also requires using rudder and aileron to turn, as the ailerons are weak on Pushers like this. But once you figure that all out, it is pleasing to fly. It flies very sweetly and is very smooth. It has lots of lift and can glide a long time with the flaps down. It is a fun airplane and really draws the spectators. There is not much room in this for a camera as the Raven, but with a lightweight camera like my Cisco Flip HD, it easily can be placed anywhere on the plane.
Here are some specs: Wing Span: 2500 mm.. (Approx 8 feet) Weight: 2500g-2700 g Length: 1080 mm (Approx 3 feet, 4 inches) Wing Area: 325.dm (squared) Wing Loading: 76-83g/dm (squared) Airfoil: Eppler 374 Modified 6 Channel Radio with 4 mini servos and 2 standard servos required. (Without flaps-4) Motor: (38-42) 1.7 kV, ESC: 30 amp min. with smaller motor, 40-60 amp min. with larger motor
Note* This is a camera platform. It does not need a larger motor to get high and take pictures. Pusher Props recommended: 10x6 to 12x8, 2 bladed. 3 blade 10x6-11x6. I used a 10x6 2 blade, non pusher, symmetrical prop.
Battery. I used an 1800 and a 2200, 11.1 volt, 3 Cell LiPo battery in mine and it works just fine.
They recommend a 3500 3S, or a 4000 4S. Overkill in my opinion! You will break the wings if you over stress this thing trying to do tight loops.
