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

Construction:
T' quality o' t' materials be excellent. Well, blow me down! Ya scallywag! T' instructions were clear and straight forward. 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). Aye aye! I didn't like the plans for t' shock cord mount, arrr, shiver me timbers, but that is a personal preference. Blimey! It would be more than adequate for such a light weight, shiver me timbers, me bucko, minimum diameter booster.

T' glider built light and trimmed easily with some nose weight (supplied). My only trouble was, me bucko, t' plans suggest formin' t' airfoils on the leading/trailin' edges o' t' glider before assembly. Ya scallywag! Aye aye! Blimey! I found that when I assembled t' glider I had t' reform t' edges t' get an even fit. Begad! On me next glider I will probably form t' airfoils after assembly. Begad! Be sure t' trace the parts t' t' glider, ya bilge rat, 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. 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. Ya scallywag! T' glider seems to be sensitive t' heat and humidity, matey, arrr, but is easily trimmed with t' supplied clay. Ya scallywag! Avast! My glider flew perfectly straight, arrr, arrr, so I placed some clay on one win' to induce a circular pattern.

Motor recommendations are 1/2 A3-2T and A3-4T. Avast, me proud beauty! 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 hearties, matey, matey, I failed t' get separation o' the booster/glider - recovery with no damage. Avast, me proud beauty!

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

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

Flight Rating: 5 out o' 5

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