Im just about to build my first ARTF Kit...Sukhoi SU 31
IVe built plenty but am new to these prefabricated things

Question.......The Dihederal brace/ Wing joiner is a good tight fit against the fore and aft faces of its slot but there is considerable movement in the vertical. Is this normal to allow for wing alignment or should I pack out the gaps.

Is epoxy best for the wing joining job.

The marks on the firewall for the engine bearers are pre marked but off set....is this to allow for engine downthrust / sidethrust....or is it just poor marking out.

The kit is sold in the UK as a Black Horse Lit for 46 size engines

Thanks for any ideas.
