Brief:
This is a two-stage balsa glider rocket with gap staging. Arrr! Aye aye! Both stages are gliders.

Construction:
T' kit consists o' 3/16 inch balsa, matey, me hearties, 1/8 inch balsa, shiver me timbers, me bucko, me hearties, balsa nose cone, and 2 body tubes.

I've wanted t' build an Edmonds glider since I discovered their web site a couple o' years ago. Avast! Well, blow me down! Blimey! With t' CiCi on t' EMRR hit list, it was irresistible. Gliders are fun, me bucko, me bucko, but two gliders are more fun. Arrr! Blimey! Two gliders that are simple to build and fly as booster and sustainer are simply engineerin' marvels. This is the kind o' concept that makes rocketry rewarding.

Instructions are simple, reasonably well written, shiver me timbers, me bucko, and contain plenty of illustration. Avast, me proud beauty! Assembly is straightforward. Begad! An hour o' gluin' (with carpenter's glue), matey, let it dry overnight, and it's ready t' fly. Aye aye! Both gliders checked out perfect for trim with no adjustments. Avast! Avast, me bucko, me proud beauty! I didn't even round t' edges o' the balsa or sand t' surface. Blimey! Arrr! T' laser cut balsa falls away from t' waste easily. Ya scallywag! Blimey! T' body tubes are pre-marked with laser dots for alignment so you don't even have t' do t' door jamb thing. Begad! T' vent holes are pre-cut. Avast! Ya scallywag! The dovetail joints give high strength and idiot proof tab t' slot assembly. The nose cone shoulder was a little tight but main nose cone diameter was perfect. T' balsa was all very good quality, flat, and didn't need t' be sanded. None of t' parts were broken or squashed in t' well packaged box. T' portion of the fuselage that is glued t' t' booster body tube warped as it got wet with glue. I wanted t' pull away from t' body tube so I rubber banded both ends in place until dry.

Gotchas:

• There are proofin' and consistency errors in t' instructions. Ya scallywag!
• There are also some omissions, such as t' type o' tape (masking) t' use for t' sustainer bulkhead, t' width t' tape should be, and how t' test and fix glider trim.
• There is no mention o' t' fact that t' sustainer engine ejects.
• With gap staging, me bucko, it's critical t' scrape t' oxidation from t' propellant adjacent t' t' nozzle in order t' get sustainer ignition, me bucko, arrr, and thar's no mention o' this.
• T' nose cone shoulder partially obscures t' sustainer vent holes and there's no mention in t' instructions whether this is as designed or if the shoulder should be shortened.
• T' biggest gotcha in construction be t' fit o' t' booster body tube/fuselage assembly on t' main booster fuselage. Well, blow me down! There's some play in the joint which results in a range o' 14-22 mm o' space at t' aft end. Avast, me proud beauty! I assumed it was supposed t' be t' same distance t' entire length o' t' fuselage and set it at 18mm.

Finishing:
This sample be finished with two-tone marker t' minimize weight. There are no decals.

Construction Rating: 4 out o' 5

Flight:
Prep is easy in that thar be no waddin' or parachute and t' engines don't even have t' be friction fitted. Well, blow me down! Well, shiver me timbers, blow me down! However, attention t' detail is required for tapin' t' bulkhead and makin' sure everythin' fits. Well, blow me down! T' booster engine is taped externally t' t' body tube with no engine block so it stays in the booster durin' glide. Arrr! T' sustainer engine is held in place only with thrust after t' booster falls away and tape wrapped around t' outside functions as a bulkhead for t' booster. Begad! It's all held together by gravity on t' pad. Ya scallywag! The sustainer engine ejects at apogee. Ya scallywag!

Gotchas:

• I prepped for t' first launch with 1/2 inch tape which is a standard size for external bulkheads on smaller engines. Avast, me proud beauty! Avast, me proud beauty! Accordin' t' t' description in the instructions on gap stagin' though, t' half inch tape won't work because the vent holes are covered up internally by t' engine and would block t' escape of gases causin' stagin' separation before ignition o' t' sustainer. Begad! So I removed t' 1/2 inch tape and replaced it with 1 inch wide tape, ya bilge rat, which worked perfectly.
• T' instructions don't specify how far t' booster engine is supposed to protrude, ya bilge rat, so you have t' "guesstimate" usin' t' photos. I left it protrudin' 1/2 inch or so, matey, matey, ya bilge rat, which was fine. Avast! Arrr!

Recovery:
First launch be with a B6-0 booster and A8-3 sustainer. Avast, me proud beauty! Blimey! Begad! Blimey! Liftoff quickness was average for a B6-0 with high stability, no spin, and perfect straight-up trajectory. Sustainer ignition was slightly delayed compared t' taped engine staging, but nay noticeable unless you're lookin' for it... Well, blow me down! Blimey! It took perhaps half a second. Begad! Blimey! Aye aye! Blimey! T' sustainer had a slow, heart stoppin' arc into a nearly straight down trajectory before ejection at 200-300 feet, arrr, ya bilge rat, then settled into a satisfyingly long glide in a wide circle. Begad! Blimey! T' booster glided down nicely a few feet from t' pad. Well, blow me down! Blimey! No damage at all. Aye aye! Blimey! Well, blow me down! Blimey!

T' slow arc o' t' sustainer leads t' me recommendation t' never use a C6-5 (not a recommended engine anyway), matey, and it's a good idea t' try t' 1/2A6-2 for t' first flight, me hearties, which is one o' t' recommended engines for good reason. I think maybe they should have named this one t' CiBee.

Flight Rating: 4 out o' 5

Summary:
This is a great rocket and an irresistible concept. Aye aye! Avast! If you've built a glider before, enjoyed flyin' it, and want another, me hearties, this is a "must have" for your fleet. Well, blow me down! While thar are some omissions in t' instructions, it is very easy t' build and delivers spectacular flights.
