Well, here goes. After a couple of weeks of waiting, the *huge* box finally turned up After a quick inspection, I'm very impressed by the quality of the contents. The wings are both pre-joined with the ailerons hinged with metal hinges. The rudder is also already hinged to the fin. The covering is *proper* heat shrink type covering, as opposed to the sticky-back shelf-paper style stuff on some of the cheaper models out there. The cowl is a high quality fibreglass job which has already been painted, as are the wheel spats. The supplied hardware pack is very good, with metric screws etc with decent heads on them. Absolutely everything you need to complete this model is there, right down to the pilot figure and the bright red 70mm spinner. All I'm going to have to do with this model is throw my radio gear and a bottle of glue in the box and shake it up I reckon

The manual says to start with the aileron servos. These are hatched into the upper surface of the lower wing. They would look better (ie out of sight) hatched into the *lower* surface of the wing, but there you go. I ran into a problem here......the wing recesses are just too small to accommodate a normal sized servo. The hatch cover has a slot cut in it to allow the servo horn to protrude through from the inside. Unfortunately, if you install the servo as per the instructions so as to allow enough servo travel, standard servos are just not going to fit. My solution is to fit a couple of Hitec HS225BB servos instead. These are higher torque than a standard servo, but are smaller (and lighter).
You'll see (in the attached image) that there are pieces of line laid in the wing to enable you to pull your servo leads through. Great idea You'll need extension leads for your servos too. I've gone for 24" extensions to allow for ease of wing attachment at the field.

The lower wing is fixed to the fuse with 3 metal screws. These thread into blind nuts that have already been fitted to the mounting block in the fuse. The wing looks like it has been bandaged with a fibreglass strip around the middle and the holes in the wing feel very solid when tightening the screws up. Once done up, the wing is held in place very solidly.

Here's the inside of the fuse. You can see the pre-drilled holes for the lower wing mounting bolts. The former behind the front mounting block looks like it's twisted......it's not . The digital camera distorts stuff a little when it's on the macro setting, but I get a much clearer photo that way

With the wing bolted on, there's a little bit of a gap between the TE and LE and the fuse, but it's not that bad. I'll probably use some radio box tape to cover the gap whenever I fly it, just to stop the oil getting in.

I installed the horizontal stab next. The slot in the rear of the fuse for the stab to go through is actually sandwiched top and bottom with solid balsa, roughly the same thickness as the stab. The instructions call for epoxy to be applied and then for the stab to be slid into place. However, it's a very tight fit (with perfect alignment too I might add) and would force most of the epoxy out the other side.....all over your nicely covered stab. Instead, I chose to get the stab into place and then wick thin CA all around the joint to hold it in place. Then I cut 3 short plugs from a piece of dowel and 'pinned' the stab in place using the balsa above and below it. I epoxied the plugs in place. It's rock solid and far neater than smearing epoxy all over it!

Fin is next and it's a very simple affair. Put the epoxy in the slot and slide the fin and rudder into place. The slot appears to have been cut with a router into a solid block of balsa, so again, alignment is perfect already.

There is an area at the front of the fin that looks a bit ordinary once it's all in. Easily fixed though, if you can find covering material the same colour.
