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

Construction:
T' quality o' t' materials was excellent. Ya scallywag! Well, blow me down! T' instructions were clear and straight forward. Begad! T' supplied jigs for win' dihedral were adequate, but I found I needed t' secure them t' t' work surface (tape). Well, blow me down! Ahoy! I didn't like the plans for t' shock cord mount, me hearties, but that is a personal preference. Well, blow me down! 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, shiver me timbers, me hearties, t' plans suggest formin' t' airfoils on the leading/trailin' edges o' t' glider before assembly. I found that when I assembled t' glider I had t' reform t' edges t' get an even fit. Ahoy! On me next glider I will probably form t' airfoils after assembly. Avast! Blimey! 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. Aye aye! Arrr! 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. Arrr! Blimey! T' glider seems to be sensitive t' heat and humidity, arrr, ya bilge rat, but is easily trimmed with t' supplied clay. Ya scallywag! Blimey! Begad! Blimey! My glider flew perfectly straight, me bucko, 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. Aye aye! Blimey! Avast, arrr, me proud beauty! Blimey! 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, I failed t' get separation o' the booster/glider - recovery with no damage. Begad! Blimey! Ahoy! Blimey!

On t' first flight with t' A3-4T, shiver me timbers, 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. On t' final flight t' wind picked up a bit and t' glider just kept goin' like t' energizer bunny. Well, blow me down! Blimey! 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! This bird really didn't want t' come down.

Recovery:
T' only negative (as I saw it) was t' shock cord mountin' technique. The plans call for cuttin' 2 slots in t' body tube and slippin' t' elastic through and knotting. Aye aye! 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, me hearties, but t' booster is so light t' it could free-fall without concern. Arrr! Avast! I love t' design o' t' glider!

Flight Rating: 5 out o' 5

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