any tips for someone about to build there first plane(Trainer Kit)?

uhmm...build on a completely flat surface, don't use really warped wood, make good joints to make it strong, but also build light...and well its really late so i'm goin to bed. maybe ill come up with better stuff 2morrow.

Read the instructions before starting (preferably twice)

Try to avoid using too much glue. For your first plane I suggest you use PVA/Aliphilactic glue as it gives you time to reposition, take apart if you do anything wrong (which you probably will do, I did, and still do). But use epoxy if told to in the instructions for any part.

Trial fit every thing before using glue.

Come back to RCU if you have any issues. We are keen to help!

So which plane you building? Have you got your engine yet? Have you joined a club to learn to fly?

Try to find a local builder to drop in and oversee your work from time to time.... have a few pints ready to share.

Ditto! Read the instructions until you UNDERSTAND what they are saying.

Here's an example of what I mean:

A friend once phoned me because he didn't understand something. The instructions said "Place the Trailing Edge so that the 1/8" notch is towards the center."

He said "The trailing edge is FULL of notches, there's one for every rib!"

I told him to check if the notch on one end was a different size than the others. Sure enough, all of the notches were 3/32" except one, which was 1/8". It was only 1/32" larger than the others, and not easy to spot unless you were LOOKING for it.
