Hello. I have an PML Phobos rocket that is partially finished from 7 years ago. Unfortunately, I had dripped epoxy into the main tube and it prevents the proper operation of the piston ejection system. Instead of trying to scrape it off somehow (it is deep in the tubing), I was wondering if I could just cut the piston out and convert it to a standard ejection system? I plan on using mid power motors in this rocket with a motor mount conversion to 29mm.

Here is some info about the Phobos:
• Pre-slotted Quantum Tube airframe
• 12" payload section
• Dura-Chute nylon parachute
• Plastic nosecone
• 38mm
• Piston ejection system
• G-10 fins
• Linear Rail Lugs for 10/10 launch rails

Thank you,
Roland

I'm sure with the right parts and a sharp hobby knife you can do the conversion. Sounds like a really nice kit.

Thanks!
Today I started working on it again. Hope to have it finished in a few weeks, ready to paint.

Here is the Phobos sans paint! I just need to jb weld the motor retainer on. Thinking of a paint scheme - maybe a metallic blue. Oh and I have a nomex parachute protector on order. It no longer has the piston. I changed to use a swivel for the parachute too. It needs a backup as the swivel looks very small and I don't like everything riding on a tiny loop of welded steel.
