Model Rocket Motor Retention Methods

[@aquagreen73s5]

Excellent video. The hobby has come a long way since launching the Estes kits at the local park back in 1979.

[@apogeerockets]

Thanks. A lot has changed

I love how real the dude is. "May your...uhh...well anyway we'll see you next time!" Lol

[@apogeerockets]

Yea, Tim forgot the quote haha.

[@natemoorman4562]

for that last case you mentioned, I've found a better solution than friction. you can screw a small bracket into the centering ring which does an offset and holds the motor into the mount!

Hi Nate - got a repair job to do and this sounds interesting. Do you have any photos or illustrations of this?

I used the no engine block trick in my Estes argent. I flew it on a 29 mm I105 motor it worked well. It flew to about 7000 ft and traveled At mach 2.3. The upper body tube I turned into a payload section and flew weather instruments with a speedometer and an altimeter in it and I got it back safely.

Ok, burning questions, can aerotech engines be used in estes rockets, star orbiter and maxi mosquito?

[@apogeerockets]

Yes. Go for it.

Great Video Tim! you make it look so easy

For the last rocket with the rear centering ring all the way aft what about fabricating kaplow clips?

[@philorida]

How far does the motor mount tube need to stick out from the centering ring to epoxy the flange?

Tim I currently use a grey Estes screw on engine retainer on my 29mm madcow solar express that i use but somehow whenever I insert an aerotech F20-4w the screwcap doesn't go on all the way to hold the engine in place, am I using the wrong retainer ?

[@apogeerockets]

It's hard to say without seeing it. Sorry.

[@b.h9186]

What is the highest category i can fly without a certification 1 ?

[@apogeerockets]

It depends. If you're older than 18, then a G80.
