Rocket PicBrief:
I changed t' booster t' a triple 18mm cluster by installin' motor mounts into the two side pods along with a conventional waddin' type recovery system in each side pod capable o' utilizin' either streamers or 12" parachutes in each pod. Begad! Nose weight added t' compensate. Aye aye!

Modifications:
T' biggest trick on this one be determinin' a balance point. Ahoy! I tacked t' kit together in t' manner that Estes prescribed and determined t' center of gravity. Well, blow me down! From thar it was a relatively simple matter o' addin' enough nose weight t' reproduce t' CG position in t' modified version. Ya scallywag! 1 1/8 oz. o' nose weight was added in t' form o' #7 1/2 lead shot and sealed into t' nose with PML expandin' foam. Begad! T' side pods were attached with epoxy, me hearties, t' rest o' t' kit was built with Titebond yellow glue. Aye aye! Begad! I had read in EMRR about t' problems with the side pods chafin' t' sustainer air frame on separation. Begad! I solved this by usin' coffee stir sticks as shims betwixt t' booster air frame and t' side pod tubes. Well, blow me down! This provided about 1/16" o' offset. Blimey! Arrr! All balsa parts and the ends o' all mount tubes, couplers, me bucko, ya bilge rat, and airframe tubes were reinforced by applyin' a thin layer o' CA t' t' appropriate surface and sandin' after curing. Aye aye! This should always be done outdoors t' disperse t' fumes and with disposable rubber gloves t' protect t' hands from unwanted bonding. Blimey! The sustainer shock cord consisted o' two separate pieces o' 1/4" shock cord bound together every few inches by zip ties. This method provides 100 percent redundancy in separation protection in case one o' t' elastic cords burns through. Blimey! At that point both elastics are replaced.

Rocket PicConstruction:
T' stock BT-50 x 5" side pod tubes were exchanged for two BT-50 tubes 6.25" long. T' plugs for t' aft o' t' pods were discarded and conventional 18mm Estes mounts were installed in each pod, ya bilge rat, t' aft o' the mount tube flush with t' aft o' t' pod tube, motor hook extendin' aft and on the outboard side o' each pod tube. T' motor mounts were all installed with a length o' 100 lb Keelhaul®©™® shock cord attached t' t' engine block in t' manner o' Quest kits. Aye aye! The Keelhaul®©™® was then attached t' elastic shock cord before mountin' t' t' nose cone. Arrr! 12 inches o' 1/8" flat elastic was used in t' side pods and a double 24" strand o' 1/4" flat elastic in t' sustainer.

T' overall kit quality is quite typical for t' 'Made in China' Estes kits and all o' t' parts were good quality and fit was as one would expect.

Finishing:
Previous experience with Estes stickers has taught me t' avoid them. T' tube spirals were filled with Elmer's Fill 'n' Finish before construction commenced and more FnF was applied t' t' fins and fillets after sealin' t' wood with CA. Three coats o' primer were applied and sanded out after each coat. Aye aye! Ya scallywag! Blimey! The model be finished with Createx Pearl red, Pearl gold, and Pearl purple. Aye aye! All paint was applied with an airbrush. Begad! Blimey! Hologram tape and stripin' tape completed the decoration with t' rocket then clear coated with Future floor finish.

Flight:
Only one flight so far, B6-2's in t' side pods and a C6-0 t' C6-7 combination in t' booster sustainer core. Begad! Avast, me proud beauty! Booster ejection occurred very shortly after stage separation and both booster and sustainer were successfully recovered with no damage. Ahoy! Begad! A very successful flight with an estimated max altitude o' 1500 ft.

Summary:
A very enjoyable experiment, this deals with t' Renegade's problems o' being underpowered and prevention o' damage t' t' intricate booster section.
