this is a very easy plane to build very light too, i got one question though, where does the 2 little blue triangle pieces go ? i think under the horsiontil stab (excuse the horrible spelling). info please thanks

i put them on each side of the tail fin.

Yes, they are made to support the vertical stab attachment point which is known to be weak. I never used mine and didnt have any problems with my stab but heard of plenty of guys that did. And how mine held on with the awsome flat spins that it did I'll never know.
