well my hand launch did not go well today, i threw it up and it stalled , cracked the fuselage and elevon and broke some of the thrust tube off .
easily fixed with hot melt , however . i think 3S even though it screams blue murder in the air is probably a risk on launching with this plane .
infact searching youtube videos you need to go all the way up to 6s before you can just let the plane go . even 4s needs a good throw .
this plane comes in at about 1.2kg , and has about 1.1kg of thrust at 550 watts 45 amps.
it came with an upgraded 70amp esc . but the motor is only rated at 500 watts . 4370 kv

there is a 4s version unit 880 watts at 55 amps 1.7kg thrust 3550 kv . speed about 90 mph with this versus 80mph on the 3s version .
i might have to go with this . undecided as yet .
