Hello

I see Olbill is a fan of this configuration. I would like to hear
about advantages and disdavantages on this tipe of construction. I try
a search on the Don's yahoo goups archive and was little what I
found. (probably because I used bad keywords to search).

So far the droped boom can lower the CG, reducing the nose up moment
because the propeller trust. Also, but dont know how important can be,
the tail will be more (or less) affected from downwash, turning into
an advantage or disadvantage.

And a clear disadvantage is the increase of drag, because the droped
boom and extra posts holding tail surface. If I dont reasemble bad,
Don have told that "all other parts of model, not taking into acount
surfaces, contrubutes in 1/3 of total drag".

So.. what are the pros and cons from your point of view?
