i just got a .46 size edge 540 from seagull hobbies.
i plan to put a gms 76 in it with a 14/4w apc prop.
its same wieght as the saito 72 and os 70 fs give or take an ounce.

my quess is that the top of the motor box is open, should this area be strenthened or not.
usually its enclosed or a piece is provided to cap it off.??

also want to know if the gear needs help too,due to the added wieght up front.

all this while keepin at around 6 lbs lol

any help is great
thanx
