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

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

T' glider built light and trimmed easily with some nose weight (supplied). My only trouble was, matey, t' plans suggest formin' t' airfoils on the leading/trailin' edges o' t' glider before assembly. Arrr! I found that when I assembled t' glider I had t' reform t' edges t' get an even fit. Aye aye! 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. Well, blow me down! 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. T' glider seems to be sensitive t' heat and humidity, shiver me timbers, but is easily trimmed with t' supplied clay. Blimey! My glider flew perfectly straight, so I placed some clay on one win' to induce a circular pattern.

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

On t' first flight with t' A3-4T, I got perfect boost, me bucko, separation and a beautiful long circlin' glide (much applause). Avast, me proud beauty! For all t' above flights the temperature was 80+ with a 5-10 MPH wind. Arrr! On t' final flight t' wind picked up a bit and t' glider just kept goin' like t' energizer bunny. Well, blow me down! 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. Blimey! Aye aye! This bird really didn't want t' come down.

Recovery:
T' only negative (as I saw it) be t' shock cord mountin' technique. 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, me hearties, but t' thickness even further reduced t' space for t' waddin' and streamer. Begad! I will have t' device another means, matey, ya bilge rat, me hearties, but t' booster is so light t' it could free-fall without concern. Well, blow me down! I love t' design o' t' glider!

Flight Rating: 5 out o' 5

Summary:
I really enjoyed this kit, ya bilge rat, and went out and bought a second immediately (see note about tracin' plans for glider!). Well, me bucko, blow me down! There are no significant cons, and I can't express how much I enjoyed t' flights!
