RE: Model Tech Extra 300 ARF with a 40 FX?
I have been flying the MT 300 w/OS 52 surpass which is heavier than 40fx for about 4 years.
A little firewall reinforcement and 1.75oz of lead inside fuse near tail. No glassing of wings or anything special. This plane is so fun I cant descibe it! It will perform any trick in the book!
Best 89 bucks you will ever spend
