Brief:
I was full o' good ideas for t' glider that I was goin' t' make. Blimey! None o' these came t' be and instead I made a pop
pod glider. I foolishly went for a large (ish) glider as I did nay want t' simply replicate a glider that I already
had. Aye aye! T' result was a glider that needs at least a D t' lift it, but will also shred on a D.
Construction:
T' glider itself consists o' a four panel win' with a three panel tail. Ya scallywag! Blimey! Two 1mm by 1mm spruces act as side by side booms, with a front fuselage made out o' 3/8th inch balsa. Aye aye! Blimey! T' pop pod was t' pod from a Quest Flat Cat.
Win' Construction:
2 panels. Begad! 3.5 by 6 inch
2 panels, matey, 6 inch long with ends measurin' 2 inch and 3.5 inch
T' centre panels were glued together with one win' tip 1 inch o' t' bench.
When t' glue had dried, t' outer win' panels were added, again with a one inch lift.
Tail:
Two panels o' balsa measured 5 inch with t' sides bein' 2 and 2.5 inch, me bucko, arrr, were glued together. Begad! T' angle formed matched t' front wing.
A rudder be attached underneath, this panel measured 4 by 2 inch, matey, shiver me timbers, and was trimmed down somewhat.
Booms:
These were made from 1mm by 1mm spruce (which turned out t' be a big mistake) both rods were 17 inches long. Begad! Blimey!
T' booms were glued t' t' outside edges o' t' tail, and them t' front win' was glued t' t' front.
Fuselage:
A 15 inch piece o' 3/8th square balsa formed t' fuselage. A 3 inches piece be glued t' t' top end o' the fuselage. Begad! Blimey! When this dried, a front cavity was made t' hold balancin' mass, matey, and t' hook/catch mechanism was cut out. Two thin pieces o' balsa were then glued t' t' out side edges o' t' front fuselage t' complete t' cavity box and edge off t' catch. Ya scallywag! Blimey! Blimey! Blimey! This whole front end be very similar t' front end o' a Quest Flat Cat t' fuselage was then glued to t' front wing.
Pop Pod:
This was a steal from t' Quest Flat Cat.
Finishing:
T' whole glider was sanded down, all edges were rounded and a slight aerofoil added t' t' liftin' surfaces. Ya scallywag! The rocket was then sealed.
T' design be that as t' aft booms were out o' t' way o' t' motor thrust, thar was no need t' protect the fuselage. Arrr! Blimey! Blimey! Blimey! I knew t' glider would be tail heavy so t' cavity at t' front would take mass t' balance. Avast, me proud beauty! Blimey!
Test Glides:
Several test glides were needed t' get t' glide right, in t' end a big lump o' lead was needed t' balance the glider this is where t' glider's name comes from.
Flights:
First flight was on a B4-2
Lift was straight but nay t' high, me bucko, t' lump o' lead at t' front came out and she fell tail down my fault. Aye aye!
Second flight was on t' came motor with a lump o' clay actin' as t' mass at t' front. Arrr! Blimey! Blimey! Blimey! Again t' lift was straight, arrr, but t' pop pod did nay pop! Blimey! T' whole thin' came in nose first, arrr, thar was a lot o' balsa t' glue back together.
Third flight was a few days later, me bucko, shiver me timbers, and after repairs. Avast! Well, blow me down! This time a C6-3 was used, t' higher thrust made t' whole thin' shake on lift, arrr, so much so that t' tail shredded. T' glider, now heavy, nosed in again more gluing.
Fourth flight. Arrr! Avast! Again a C6-3 was used, shiver me timbers, t' flight was straight again with less wobble, matey, ya bilge rat, ejection was clean and t' glider glided in on a steep angle. Begad! Arrr! There was damage.
Summary:
T' glider is too heavy for an 18mm motor and a D would rip it apart. Avast, me proud beauty! I should learn t' walk before I can run, I have had me own design smaller gliders perform very well, and I've had large kit gliders work, shiver me timbers, but I'm nay quite ready for t' large birds yet.
