The fuselage tailboom and fin is a strong all carbon one piece molding. The under-wing battery compartment is a generous 13 cm x 4 cm x 4 cm. The wing is fixed by three M3 bolts with threaded hard points already installed in the fuselage. Note people usually fit the elevator servo under the rear wing hold down bolt.
The one piece wing is a massively strong all carbon affair with a substantial spar supplementing the bullet proof wing skins. The wing is very slim and even 8 mm thick aileron servos will stand proud of the skin. The wing has comparatively small 35 mm x 24 mm hatches for the aileron servos. No flap servo access hatch has been installed by the manufacturer so that will have to be done by the customer if the flapped version is selected.
The tailplane is a lightweight molding which fits an a slot in the rear of the fin. This was quite tight in our test model and may need sanding slightly to allow the tailplane to be slid into place. Gluing in the tailplane, the control horns, the firewall (supplied) and installing the RC is the only construction work required.
The only accessories supplied are bulged aileron servo covers, 2 aileron horns and a 30 mm firewall. The customer will need to supply the aileron linkages, elevator horn, tail pushrod, and flap horns and linkages for four servo wing versions. Note the nose is quite short and the tail moment arm is long, so it is worthwhile keeping the tail pushrod as light as possible. Also the fuse front is quite bulbous and when we fitted a prop for the photo shoot the blades would not fold completely when using either GM 30 mm or VM Pro 30 mm spinners. The blades folded reasonably well when using a GM 32 mm spinner with a GM 30 mm cone, but a larger yoke may be even better.
See this RCGroups thread for more info about the model.
