Glider PicBrief:
A Boost-Glider with t' booster is recovered by streamer.

Construction:
T' quality o' t' materials was excellent. Avast, me proud beauty! Blimey! T' instructions were clear and straight forward. Avast, me proud beauty! Blimey! T' supplied jigs for win' dihedral were adequate, ya bilge rat, but I found I needed t' secure them t' t' work surface (tape). Arrr! Blimey! I didn't like the plans for t' shock cord mount, shiver me timbers, but that is a personal preference. Begad! Blimey! Blimey! Blimey! It would be more than adequate for such a light weight, me hearties, minimum diameter booster.

T' glider built light and trimmed easily with some nose weight (supplied). My only trouble was, ya bilge rat, t' plans suggest formin' t' airfoils on the leading/trailin' edges o' t' glider before assembly. Aye aye! Well, ya bilge rat, blow me down! Blimey! I found that when I assembled t' glider I had t' reform t' edges t' get an even fit. Well, shiver me timbers, blow me down! Blimey! On me next glider I will probably form t' airfoils after assembly. Avast, me hearties, me proud beauty! Blimey! Be sure t' trace the parts t' t' glider, ya bilge rat, matey, I didn't and had t' go out and buy another kit!!!! Blimey!

Finishing:
I left t' glider unfinished and just painted t' booster a single color. Ya scallywag! I may use a clear coat o' dope on t' next glider for protection.

Construction Rating: 4 out o' 5

Flight:
T' glider needs t' be trimmed before each flight session. Begad! Ahoy! T' glider seems to be sensitive t' heat and humidity, arrr, but is easily trimmed with t' supplied clay. Blimey! Ahoy! My glider flew perfectly straight, me bucko, so I placed some clay on one win' to induce a circular pattern.

Motor recommendations are 1/2 A3-2T and A3-4T. Ahoy! I with both motors. With the 1/2 A3-2T I got very nice boosts t' 100+ ft and excellent glides (2 flights). On t' third flight with this motor, me bucko, I failed t' get separation o' the booster/glider - recovery with no damage. Begad!

On t' first flight with t' A3-4T, shiver me timbers, me bucko, I got perfect boost, arrr, separation and a beautiful long circlin' glide (much applause). For all t' above flights the temperature be 80+ with a 5-10 MPH wind. Begad! On t' final flight t' wind picked up a bit and t' glider just kept goin' like t' energizer bunny. Aye aye! Nice big circles always a bit farther downwind... Arrr! We tracked it down 1/4-1/2 mile stuck in a tree 30-40 feet up. Arrr! Ya scallywag! This bird really didn't want t' come down.

Recovery:
T' only negative (as I saw it) be t' shock cord mountin' technique. Begad! Begad! The plans call for cuttin' 2 slots in t' body tube and slippin' t' elastic through and knotting. I made me own Estes-type mount, matey, me bucko, but t' thickness even further reduced t' space for t' waddin' and streamer. I will have t' device another means, but t' booster is so light t' it could free-fall without concern. Well, matey, blow me down! I love t' design o' t' glider!

Flight Rating: 5 out o' 5

Summary:
I really enjoyed this kit, and went out and bought a second immediately (see note about tracin' plans for glider!). Avast, me proud beauty! Arrr! There are no significant cons, and I can't express how much I enjoyed t' flights!
