Brief:
RMS Motor Retainer

Discussion:
T' 29mm motor retainer can now handle Aerotech's 29/40-120 motors, ya bilge rat, too. Aye aye! Ahoy! Blimey! T' retainer comes in 2 pieces packaged inside a plastic bag with simple instructions. Begad! Arrr! Blimey! One threaded retainer "ring" fits over t' motor tube like a collar. Then a threaded cap that screws on t' end o' t' ring. Ahoy! Well, blow me down! Blimey! As with typical RMS stuff, matey, t' RMS aft closure still sits on t' motor tube. Then t' retainer rin' surrounds both t' tube and t' aft closure. T' retainer rin' is epoxied with high heat JB Weld Epoxy, t' kind rated for 600 degrees F. Blimey! Simply screw t' cap onto t' rin' t' hold your RMS system firmly in place.

Pros: Instructions are easy t' follow with this high quality product. T' installation is easy, but you must be sure t' plan t' installation t' insure you have enough clearance (about .250") betwixt t' centerin' rin' and t' end o' t' motor tube. Well, blow me down! You may also want t' take into account t' placement o' t' aft centerin' rin' BEFORE you install t' ring. Begad! I chose t' put t' rin' on t' motor mount tube o' an Aerotech HV Arrrrrrrcas first. Avast! Avast, me proud beauty! Since I had put CA glue on t' inner surface o' t' motor tube, had t' sand both t' exterior (with 80 grit paper) and interior (with 220, then 320 grit paper) o' t' tube t' insure a proper fit for t' ring, shiver me timbers, I had anticipated that it would have been difficult t' do all this after t' motor tube had been installed in t' body tube. Then I used a Dremel tool with t' sander drum t' widen t' Aerotech Aerofiber centerin' rin' hole t' fit around t' installed Aeropack retainer rin' and used epoxy t' fill t' space betwixt t' widened rin' hole and t' motor tube. Avast, ya bilge rat, me proud beauty! T' installation looks great, is tough, fire proof, matey, and makes it easy t' stand your rocket on a flat surface.

Cons: It is a pricy component t' add t' a rocket, at about $25 after shippin' and handling, so I would only install it on rockets that aren't expendable.

Summary:
Easy t' use, just screw on, arrr, arrr, screw off. Arrr! Excellent, matey, shiver me timbers, quality product.

Overall Rating: 5 out o' 5
