I've built three T-bolts just recently.
Sadly, my digital cam crapped out on me, so no pics.
What I can tell you is this and this comes from my Maruader work too:
The wings will be bent
The Engine nacells will be wonky, and may or may not require bending and filling. Use Elmers Paintable Wood fill. It fills in gaps beautifully, it's very easy to clean off the model, you can trim it once it's cured, and painting it is no problem.
What I recommend for all
FW stuff:
If it's got tabs for you to stick things together: cut the damn things off and eyeball it. They're gonna be either half-filled or mis-aligned.
Warm water after it's built to saok the wings in so you can bend them into the shape you want. If you do it before, it's gonna be a crap shoot.
Wash all your parts. Then wash them again. Scrub both times.
Then wash it for all the parts you missed

Especially after you primer it and the damn primer won't stick
As for the titan....
I do have some pics of that, and my advice stays the same. The friggin toes are a @#$@#$@#ing nightmare. Cut off the tab bits that you're supposed to stick into the foot proper and eyeball it. If they're a few milimetres off you won't notice. Also, I hope you love fine detail work: the pistons will kill you.3 per front toe, 5 per ankle, 2 per leg, 3 per hip.
I've not had to pin anything, just proper sanding and lots of swearing will get anything to stick. For the arms, I'll be using rare earth magnets to get them to swivel around and so they can pop on and off for transport.
General
FW tools I recommend:
Clamps to hold the stuff in place (especially for Tbolts, this will help with the fuselage)
Proper 2 stage respirator mask. Resin dust is a *female dog*.
Good hobby saw and dremel tool.
Good understanding of how models go together. The Tbolts didn't come with instructions (nor the maruader). The Titan DOES come with instructions, so they're getting better.
Any more specific questions, please ask. I've got a lot of scars and grey hairs from
FW stuff in the past 5 months
