Go over bates certificate

hi this is John this video is on building your first high power rocket typically for level 1 certification I'm going to show you building a kit and I'm going to show you a very typical high powered kit this one is the lock for kit by lock precision lock is one of the oldest manufacturers of kits makes very nice rockets and also the materials using this kit will be ones that are familiar to you from model and mid power rocketry it's got paper tubes plywood fins apply the centering rings all easy to work with and familiar materials so let's open the package and take a look at what we got just like a model rocket kit you'll have your nose cone your airframe a motor mount tube and various parts as well as instructions one different thing to notice right off the bat that's typical of high-power kits is the tube is slotted this is because the fins are mounted not only to the surface but also go through the outside body tube and our epoxy to the motor mount tube inside now let's talk a little bit about kit selection what I have here is three sizes of motor mount - this is the motor mount tube that came with the kit it's 38 millimeter in diameter for comparison of the 29 millimeter and a 54 millimeter all three of these sizes are plausible when you choose your level one kit I've chosen this lot for partly because its simplicity longevity but also partly because I think 38 millimeter makes a good size there's a wide range of motors available in 38 millimeter in H&I impulse some other attributes that make this a good choice is its simplicity and its moderate tops this is what it's called a three fin the nose cone kit because it's basically just simple you've got your airframe one-piece nose cone three fins pre slotted pretty much everything ready to go there are a few parts we're going to switch out but basically we can build this stock and have a great flying rocket without too much complexity okay the first thing you should do when you open your kit is identify all the parts find the instructions and read through the instructions to make sure you understand how the kits going together this is fairly typical for a traditional high-power rocketry kit we have a shock cord in this case it's elastic we have a nylon parachute plywood centering rings plywood fins launch lugs now we could build this rocket totally fine with the pieces that came but there are a few substitutions and additions that are common and that I recommend the first and in my opinion most important is to replace the elastic elastic belongs in underwear not in rockets I like to use nylon strap other people prefer Kevlar but choose a bridle that's a little more durable than elastic the rule of thumb is that...
