Rocket PicBrief:
T' Point is a rear-ejection cone shaped rocket (finless) that uses t' cone as a rigid parachute for recovery.

Construction:
You will need:

  • 1 BT-20 2.25 inches long
  • 1 conical balsa nosecone (or reasonable substitute)
  • 1 piece o' 1/8 inch elastic shock cord
  • 2 peices o' heavy paper or cardstock
  • 1/16 inch balsa sheet for internal stiffeners

T' instructions were clear and logical, with good illustrations t' guide each step. Blimey! Aye aye! Build t' nose/motor tube first and while it dries, move onto t' body. You will have t' print t' body shroud and base rings on t' heavy paper. I used 100 lb. bristol board with good results. This is a good sturdy paper, me hearties, ya bilge rat, that will curve well without creasing. Begad! T' color ink went down very smoothly with nice bright saturation. Avast, me proud beauty! Ya scallywag! Take care t' line up t' overlap and tape it down straight. Ya scallywag! Avast, me bucko, me proud beauty! When gluin' t' cone together, get a couple o' scrap pieces o' balsa and clip them over t' seam (one on t' inside and one outside) with clothespins t' help make a strong bond. Well, blow me down! Avast, me proud beauty! MAKE SURE THE BALANCE POINT IS AT THE MARK IN THE INSTRUCTIONS! Since thar are no fins t' correct t' flight, shiver me timbers, me hearties, me hearties, you have t' make sure that t' CG location is correct.

Finishing:
Since t' body wrap has t' detail printed right on it, shiver me timbers, nay much is needed in t' way o' finishing. Avast, me proud beauty! Seal and paint your nosecone before gluin' t' shroud on.

Flight:
T' recommended motor is a B4-2, but I flew mine on a B6-4 (all I had in t' B class). Avast! Ahoy! T' prep is unique, because t' motor is so far forward o' t' base. t' instruction recommend makin' extensions t' t' ignitor leads, matey, me hearties, me hearties, but if you are careful, me hearties, you should be able t' hook your clips up without them touching. Arrr! T' retention device is a small rin' o' BT-20 tied t' t' shock cord, shiver me timbers, me hearties, then slipped over t' motor. Well, blow me down! Be sure t' keep your shock cord out o' t' way o' t' exhaust! No waddin' is needed, especially if you sealed t' end o' your nose cone. Begad! Flights are straight with t' smoke trail followin' up with t' rocket.

Rocket PicRecovery:
T' body o' t' rocket is supposed t' become a rigid parachute o' sorts when t' t' motor ejects t' t' rear. Avast! Avast! Remember t' warnin' about gettin' t' shock cord out o' t' exhaust? Well, me bucko, mine slipped down and on ejection was burned through. Ya scallywag! Motor case went that-away and T' Point came down like a batmitton birdie, givin' t' LCO a good look at how this rocket got its name. Blimey! I will most likely replace t' elastic cord with some Keelhaul®©™ t' prevent this happenin' in t' future.

Flight Rating: 4 out o' 5

Summary:
PRO's: Interestin' and odd. Aye aye! Sure t' turn heads when you load it up on t' rack. Body wrap makes for a sharp lookin' model with minimum effort. Begad! CON's: Easy t' burn through shock cords. Well, blow me down! Can be a pain t' prep if you have large hands. Aye aye! Ya scallywag! Might be interestin' t' scale this up for 24mm.
