id go with a 100 amp esc and a 1250kv out runner .. b4 installing the motor Id add 2 pieces of mdf Fiberboard to nose inside and behind were motor mounts
id use Monokoat. and not tissue paper then the coating. Id think a rc plane this size you would want the least weight as possible...Id like to recommend a brushless motor with a esc but Ill pass on this...a 4 cell lipo should give you enough power to get this bird off the ground... just my 1cent...
