I recently purchased a LOC Graduator as my first introduction to LMRs and
to use for Level I (or H) certification. Obviously I will need to do some
modification to the rocket. I am planning to certify using lower end H's
such as an H120 or H140 SUs (don't want to take the chance of loosing the
casing with this rocket). My modification plans so far include:
1) installing a stuffer tube to about 3/4 of the way up the airframe and
leaving a parachute compartment at the top.
2) mounting the LOC shock cord mount through the upper bulkhead of stuffer
3) fibreglassing the body tube.
4) the plywood fins are through the wall, but only protrude about 1/8"
into the tube. I was thinking about a strip of fibreglass over the fin
tab, along the inside of the tube, to "lock" the fin in place. Will I
need to fibreglass the fins?
Anything else? Are my plans suitable? There has been a lot of discussion
regarding retention systems lately - any suggestions for this particular
All suggestions are welcome.
