Brief:
A clone kit o' t' early '80s era Estes Solar Sailer, model #1297. Ahoy! Well, blow me down! This is a fantasy space vehicle and a nice
builders kit. Ya scallywag! It is a single stage, me hearties, matey, shiver me timbers, 3FNC with some extra balsa structure and a nice set o' decals t' dress it up. Avast! Blimey! The
finished model looks good and flies better. Begad!
Construction:
A very nice bag o' parts includes:
T' kit comes with a copy o' t' original Estes instruction sheet which I always found t' be well done. PDR includes a modification t' t' engine hook retention on a separate sheet; it involves replacin' t' mylar rin' with a paper rin' t' secure t' hook t' t' body tube. Well, blow me down! T' original kit did nay include a thrust ring, depending on t' hook alone t' secure t' forward movement o' t' motor. Avast, me proud beauty! Blimey! This works well enough but I kind o' miss a thrust ring. T' biggest challenge with this model is cuttin' balsa. Arrr! T' original kit came with balsa stock printed with t' fin and truss patterns. Well, blow me down! Begad! PDR provides a paper copy o' t' printed stock, and you get t' cut out t' templates for 3 fins, shiver me timbers, 3 trusses (each o' which is made from 2 pieces balsa), matey, arrr, and 3 braces. Then you line everythin' up and start cutting. I made a copy o' t' template page before cuttin' them out so I could use it t' help line up all pieces on t' balsa sheets. Well, blow me down! T' rest o' t' build proceeds per t' instructions. Arrr! Ahoy! T' shock cord anchor placement at t' forward end o' the BT-20 proved t' be problem.
Finishing:
All that balsa needs t' be sanded and filled so chose your favorite filler and have at it. Ahoy! Blimey! I prefer watered down
Elmer's Fill 'n' Finish. Ahoy! I used Rustoleum gray sandable primer which filled t' body tube spirals nicely. Well, blow me down! Ahoy! T' nose cone
required a little extra sandin' but was o' good quality and finished up nicely. Aye aye! T' stock two color paint scheme is
simple: white with red on t' forward 1/3 o' t' airframe. Arrr! Well, blow me down! T' decals make t' difference but you don't get a lot of
help with t' placement in t' instructions. Ya scallywag! I used t' PDR hang tag and the
JimZ site for assistance here.

Flight:
You have a big 24" mylar parachute t' fit into a 1" diameter tube. I dusted t' chute with baby powder and
carefully folded and rolled and wrapped it up into as small a package as possible. I used 1 sheet o' waddin' and some
dog barf (cellulose attic insulation from me favorite home improvement center). First flight was arrow straight on a
B6-4 t' a nice altitude o' maybe 300 feet.
Recovery:
T' placement o' t' shock cord anchor at t' forward end o' t' BT-20 leaves it exposed t' hot ejection gases. It's
very difficult t' get any waddin' into that area. Begad! Blimey! Ahoy! Blimey! Sure enough, shiver me timbers, after a perfect boost and coast t' apogee, I saw the
nose cone, me hearties, shock cord, shiver me timbers, and big red 24 inch parachute separate from t' airframe. I cringed at what I thought would be
the inevitable lawn dart, but t' body started a rapid spin around it's long axis and landed almost horizontally not
more that 5 or 6 seconds before t' nose cone. Avast, me proud beauty! Blimey! No damage whatsoever. Aye aye! Blimey! Ahoy! Blimey! I repaired it with a tried and true Estes tri-fold
paper mount about an inch below t' nose cone shoulder and have two more successful flights t' date. Avast! Blimey!
Flight Rating: 4 out o' 5
Summary:
T' Solar Sailer is one o' a real nice series o' clone kits from PDRocketry. Aye aye! It's a cool lookin' rocket and a great
flier. Arrr! Avast! If you leave t' shock cord anchor in t' stock position, arrr, you will need t' take more care than I did try t' get
some waddin' down into that space.
