Hello all, I have a Phoenix and a foot or so of PML 29mm phenolic. The rocket is nice looking and used to fly great (not very high, but nice slow liftoff) on D12's, except that the small aft fins often broke off. Then I tried epoxy fillets. After adding much nose weight to compensate, it probably won't fly on Estes D's or E's anymore. Here's my options:
a. Try out 24mm RMS or SU motors other (higher power) than Estes. I'm thinking that the regular engine hook on the Phoenix will no longer be sufficient motor retention, how would I need to modify my aft end? (also, are these type motors regularly available? I've seen them out of stock at a couple of web sites)
b. Replace the guts with 29mm and a Slimline or similar retainer. This option comes with other benefits from my spare parts box... A Kevlar shock cord, nice parachute and nomex shield. I don't have the centering rings, though...
c. Leave the rocket on the shelf, it's not worth it.
What would you do?
