I've started building theLindberg blue devil, which my brother in law gave me at Xmas.
At first I was discouraged by the large amounts of flash on some parts and the inaccuracies described in some on-line articles.
But, there are good points:
The hull is a good size, there's plenty of room for a buggy pack battery, etc.
I did a bath test and the model takes 1Kg in weight plus the battery pack to bring it down to the waterline.
The parts are big enough to not be fiddly or too prone to snapping off.
The detail is perhaps a little coarse but I think it will look good at a distance.
But of course it's not an MTB.
I built a little Airfix 1/400 George V and had the opposite problems. The Airfix looks nice but is too small and fragile to make a model that I can take to the lake often.
Regards,
Grant.
