Brief:
This is a two-stage balsa glider rocket with gap staging. Both stages are gliders. Avast, me proud beauty!

Construction:
T' kit consists o' 3/16 inch balsa, me bucko, 1/8 inch balsa, 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. Blimey! With t' CiCi on t' EMRR hit list, it be irresistible. Gliders are fun, ya bilge rat, but two gliders are more fun. Blimey! Two gliders that are simple to build and fly as booster and sustainer are simply engineerin' marvels. Ya scallywag! Ya scallywag! This is the kind o' concept that makes rocketry rewarding.

Instructions are simple, reasonably well written, and contain plenty of illustration. Avast! Assembly is straightforward. Begad! An hour o' gluin' (with carpenter's glue), let it dry overnight, arrr, and it's ready t' fly. Both gliders checked out perfect for trim with no adjustments. I didn't even round t' edges o' the balsa or sand t' surface. Ahoy! T' laser cut balsa falls away from t' waste easily. Ya scallywag! T' body tubes are pre-marked with laser dots for alignment so you don't even have t' do t' door jamb thing. Well, blow me down! T' vent holes are pre-cut. Well, blow me down! The dovetail joints give high strength and idiot proof tab t' slot assembly. The nose cone shoulder be a little tight but main nose cone diameter was perfect. T' balsa was all very good quality, flat, shiver me timbers, and didn't need t' be sanded. Avast, me proud beauty! Well, blow me down! None of t' parts were broken or squashed in t' well packaged box. Arrr! Well, blow me down! 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. Avast, me proud beauty!
• There are also some omissions, shiver me timbers, such as t' type o' tape (masking) t' use for t' sustainer bulkhead, me hearties, t' width t' tape should be, ya bilge rat, and how t' test and fix glider trim.
• There is no mention o' t' fact that t' sustainer engine ejects.
• With gap staging, ya bilge rat, it's critical t' scrape t' oxidation from t' propellant adjacent t' t' nozzle in order t' get sustainer ignition, 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. Ahoy! Aye aye! There's some play in the joint which results in a range o' 14-22 mm o' space at t' aft end. Arrr! Arrr! 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. Begad! Ya scallywag! 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. However, attention t' detail is required for tapin' t' bulkhead and makin' sure everythin' fits. Blimey! T' booster engine is taped externally t' t' body tube with no engine block so it stays in the booster durin' glide. Begad! 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. It's all held together by gravity on t' pad. The sustainer engine ejects at apogee.

Gotchas:

• I prepped for t' first launch with 1/2 inch tape which is a standard size for external bulkheads on smaller engines. Avast! Accordin' t' t' description in the instructions on gap stagin' though, shiver me timbers, 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. Avast! So I removed t' 1/2 inch tape and replaced it with 1 inch wide tape, 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. Ya scallywag! Avast! I left it protrudin' 1/2 inch or so, me bucko, matey, which be fine. Well, blow me down! Avast, matey, me proud beauty!

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

T' slow arc o' t' sustainer leads t' me recommendation t' never use a C6-5 (not a recommended engine anyway), and it's a good idea t' try t' 1/2A6-2 for t' first flight, me bucko, 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. Begad! If you've built a glider before, shiver me timbers, ya bilge rat, enjoyed flyin' it, and want another, this is a "must have" for your fleet. While thar are some omissions in t' instructions, ya bilge rat, me hearties, ya bilge rat, it is very easy t' build and delivers spectacular flights.

Overall Rating: 4 out o' 5
