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

Construction:
T' quality o' t' materials was excellent. Aye aye! Avast! T' instructions were clear and straight forward. Ahoy! Begad! T' supplied jigs for win' dihedral were adequate, me bucko, me bucko, but I found I needed t' secure them t' t' work surface (tape). Avast! Well, blow me down! I didn't like the plans for t' shock cord mount, but that is a personal preference. It would be more than adequate for such a light weight, arrr, minimum diameter booster.

T' glider built light and trimmed easily with some nose weight (supplied). My only trouble was, t' plans suggest formin' t' airfoils on the leading/trailin' edges o' t' glider before assembly. Begad! Begad! I found that when I assembled t' glider I had t' reform t' edges t' get an even fit. On me next glider I will probably form t' airfoils after assembly. Be sure t' trace the parts t' t' glider, I didn't and had t' go out and buy another kit!!!!

Finishing:
I left t' glider unfinished and just painted t' booster a single color. Ya scallywag! Aye aye! 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. Well, blow me down! T' glider seems to be sensitive t' heat and humidity, but is easily trimmed with t' supplied clay. Avast! Well, blow me down! My glider flew perfectly straight, so I placed some clay on one win' to induce a circular pattern. Aye aye!

Motor recommendations are 1/2 A3-2T and A3-4T. Begad! I with both motors. Avast, me proud beauty! Blimey! 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, shiver me timbers, I failed t' get separation o' the booster/glider - recovery with no damage. Avast, me proud beauty! Aye aye!

On t' first flight with t' A3-4T, I got perfect boost, separation and a beautiful long circlin' glide (much applause). Ya scallywag! For all t' above flights the temperature be 80+ with a 5-10 MPH wind. Arrr! Blimey! 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! We tracked it down 1/4-1/2 mile stuck in a tree 30-40 feet up. Ya scallywag! 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. Well, blow me down! The plans call for cuttin' 2 slots in t' body tube and slippin' t' elastic through and knotting. Arrr! I made me own Estes-type mount, matey, but t' thickness even further reduced t' space for t' waddin' and streamer. Begad! I will have t' device another means, arrr, but t' booster is so light t' it could free-fall without concern. Ya scallywag! I love t' design o' t' glider!

Flight Rating: 5 out o' 5

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