Vent hole

I have just brought a Fantom 438 from loc and i wonderd if I should drill a vent hole in the bodytube for the parachute answers on a postcard please

.

Why don't AT kits (specifically, my Strong-Arm) tell you to drill a vent hole??

Because they don't really need it.

I've flown many aerotech kits without ever using a vent hole, all without incident. I use vent holes on anything larger though.

do the instuctions call for one?

I agree with cjl and Rock_it. It probably doesn't need it if it isn't going to go past 5k really quickly (pushing mach) BUT.....it won't hurt to have one and it could stop that one fluke nosecone pop when you prove me wrong about the first statement!

Though most of my rockets tend to be fast movers I still put in vents. The most surefire way to prevent a nosecone from popping off though is to use shear pins.

Cheers guys
