Question on air pressure bleeder hole in a PML Ariel

[jnmiller]

I have a PML Ariel, which I've flown only once so far for my Level 1 cert approx 6 weeks ago (perfect flight!!). I am considering
flying this again on a J motor for a level 2 attempt, although I realize this may go close to 4000' !

I have a question though about the instructions and the placement of the bleeder hole. The instructions state to place the hole in the payload section
but did not mention placing a hole in the main airframe. Wouldn't that be necessary as well for high altitude flights?

Also can anyone recommend a good cheap tracker that doesn't require a HAM license?
I'm planning to use a JLCR to minimize drift.

Yep, I know I have a better chance of succeeding with a fat heavy rocket that will have a lower possibility of getting lost.. that's plan B !

A bleeder hole in each airframe segment is a good idea.

+1....yes vent hole in each section to bleed of trapped air pressure.

Define "cheap" tracker....never heard of anything decent for under 75-100.00 for transmitter & 250 -500 [or more] for ground receiver. There is GPS total package for 275 ish from Missleworks.

Or borrow one from club or "rent" one from fellow flier. or worst case...buy a transmitter and borrow the ground unit.

Check out Eggtimer Rocketry for for cheap tracking solutions. The good thing is you get to assemble the kits yourself! (not as hard as you may think :wink

If you can borrow one it might be free, assuming you don't break it.
