RE: New Modeller
A lot of the ARF's do have their tail fins askew but I wouldn't expect to see that in an advertisement for them.
With any ARF, expect to spend some time making sure that things like the tailfeathers are straight and adding some glue ar other strengthening to various places.
foodstick is 100% right
go for some high wing trainer time, then get a Hangar 9 PTS Mustang - They are a good trainer. (Maybe buy the mustang as the RTF version - that way you'll also get a reasonable radio with it).
A few people try to start of with inappropriate planes and end up disapointed. Don't fal into that trap. Find your local club and listen to their advice - Aeromodellers are generally great peoplewho are more than willing to help out. (like all sports, there are exceptions)
At a guess, I'd say you'd be looking at around US$450 or so to get started and can end up spending anything up to $10,000 for a Giant Scale Warbird or $25,000 for a top end turbine - those last two figures are very much the very top end of the market though.
