The venerable little 24g "blue wonder" is a hidden powerhouse with an 8x4 and has a similar power rating to the motor mentioned above. Most FT planes will fly well on those and you can see them in the early videos.
An NTM 35 series motor is over sized and heavy, as you found out, for a little FT flyer. Keep it for your next, larger plane though as those motors are great!
A decent rule of thumb is 100W per 16oz for a general easy flyer.
