Hello -I am a newbie with only a little control line flight way back when. Anyway am building a Carl Goldberg Eagle II. My plan is to build plane and seek help with training at local RC club in spring.Have a few questions

1--Wing dihedral on this kit has three options, High dihedral for 3 channel----Med. dihedral for 4 channel sport & training----Low dihedral for 4 channel with more aerobatic flight. I am going 4 channel and want the best flight out of this trainer but the manual says the low dihedral is for more experienced flyers. Is there really much difference between the two? Can I build this wing with low dihedral and train on it ok?

2--The kit shows a profile of the end view of the rudder, ailerons,elevator, they give you a cheezy little jig to make to get the two different angles by sanding. Can I run these through my shop jointer to get the angles? Seems more presice. Just a thought!

3--Rudder in my kit was twisted about 1/4 inch from top to bottom. I clamped the bottom of rudder in table vice and used vice grips on the top of rudder and twisted it a little past where I thought it was straight. Brushed on rubbing alcohol a few coats and the next day was dead on straight. Now to keep it straight should I seal it with something to keep from warping back to old shape??

I want to thank you all for any help and must say I sure am having a blast building this kit so far!!!!

Oh --one more question--Is there a fee for having someone train you to fly??
