Hey guys, thanks for the great comments. This is my first web turtorial, so I was a little unsure.
So, to continue where I left off...
Next, the wings need to be added to the area just behind the eagle head on the nose section, however, you will nedd a larger, flatter surface on which to glue them than the tiny little promontory edges that are there already, so trim the top edges of the prow using your knife at approximately a 45 degree angle, thus:

Now, glue the headlight portion of the wing plate to the appropriate place on the front of the bike forks. This should be a standard fit as per the regular headlight plates for bikes. If it's not, you've gone wrong somewhere.
Due to the angle of the cut on the winged flanges from the wing plate, they will have a leading edge that is triangular in cross-section. A controlled trim will remove this, and also the rough plastic edge from the cut. Then, glue the flat edge of the wings to the flat cut top edges of the prow:

At this point, the majority of the body of the 'bike is complete, but they are lacking bite, so it's time to add guns.
90% of the flank of the nose section is flat, inset area to which you would fix whatever armament you wish to the cruiser. In hindsight I believe it would make a better looking model if this was adapted in some way. Personally, I wanted to fill the flat with small-gauge wire mesh (pictured), but guitar wire hoses, plasticard plating, and anything else vaguely similar will do.

These 'bikes, however have it blank due to time constraints, which wasn't really noticeable one I'd finished, so meh. As with all aspects of the build, these are MY steps to making MY jetbikes, it's all totally up to you how you go about it.
Now, the bolters will be placed along the bottom half of the flat inset of the nose section, but they will need some method of standing proud of that surface, otherwise the rear of the prow obscures their line of sight.
Clip out a section of sprue frame from one of your spare sprues. Make sure it is easily twice the length of the flat surface of the nose section, and try to pick a bit that doesn't have writing on, although it's no biggy if you do, it'll just need to be filed down.
Trim one end flat, and then line the rod up with the flat inset on the nose. The rod is trapezoidal in cross-section, so make sure the wider edge is flush with the inset surface.
Roughly gaugeing the length you need (overestimating a little) cut the rod to fit. It can be filed for precision. Now glue this to the bottom part of the inset to form the bolter brackets:

The next thing you do is remove the grips and trigger guards from both bolters. Then, choosing which side your bolters will be fixed to, file flat the side of the bolter that will be glued to your 'bike. Glue your bolters, making sure they are straight and level, to the sprue brackets:

Nearly done!
The last thing to do is drill a hole in the underside of the 'bike for the flying base. I did this about one mil in front of the square block on the footplate. Then glue the two pieces of the base together, and fix it in the hole:

I left mine loose for ease of transport.
Et voila! One Adeptus Astartes jetbike to add to your legion's arsenal, so that you may better bring the light of Imperial truth to the galaxy.
Of course it needs a rider, but they are out-of-the-box bike riders unless you want some sprecialist models, but obviously that's up to you. Here are some pics of my complete jetbike riders.


I hope this tutorial has been helpful.
Now my plan while this was in member articles was to carry on with some pics of truescale marines, but it wasn't going to be a tutorial, so my progress on them will be hiding somewhere else once I get round to DLing the pictures. Ciao.
