F1Champ, to be honest, it was great fun! I was petrified of starting it. After a little persuasion from my evil side, I just decided to get going.
Once up and running, the first thing I realised was just because you pay a lot more than for a Tamiya kit, it does not mean the fit is going to better! On the contrary... And I must admit, I knew what I was getting into, having done a lot of reading up of build reviews, etc. And the smoothing out of the fit and allignment was part of the challenge/fun of the build.
Once you get your head around that concept, you must of course realise you need some different tools than those you usually use for plastic kits. Depending on how you build your platic kit, of course. Needle files, small drills, etc. - nothing major.
Also remember these are most often (248F1 for sure) "just" curbside kits. So the construction of it is not all that major. Tbh, if I can do it... not being one of the scratch-building kind. And they tend to depend on you to have done some research. Major decal placement are specified, but small ones, or race-specific ones are often not even mentioned and you have to place them yourself.
Bottom line - be patient and PREFIT EVERYTHING! I did a complete build using white glue to fit all together, then broke it all up again (very sad day that was!) and started over, glueing with CA glue ("super-glue") or... can't get onto the term now, those fowl-smelling two-part glues, painting, etc.
As for the end resut - thanks for the compliment, but I am not 100% happy. I know there's a stack of things I can improve on. BTW, if you want to get into this MM thing, here's something I allready mentioned in this GB. Try a 1:43 first!! May sound weird, but it's all the same. And where I was struggling to get to grips with some of the stuff on 1:20, once I forced myself to do a 1:43, the 1:20 scale stuff is just so much larger and easier to do!
To give an idea, I have bought some more MM kits since because of that building experience! At this stage just started off with a LMM Audi R8 - maybe that will be suitable for the upcoming racing GB... (?)
But that all is just my point of view!
Oh, and remember to wear a mask when filing or sanding resin! Apparently very dangerous/poisonous particles to inhale.
