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. Arrr! Build t' nose/motor tube first and while it dries, arrr, me hearties, move onto t' body. Avast! You will have t' print t' body shroud and base rings on t' heavy paper. Well, blow me down! I used 100 lb. Ahoy! bristol board with good results. This is a good sturdy paper, that will curve well without creasing. Arrr! T' color ink went down very smoothly with nice bright saturation. Begad! Take care t' line up t' overlap and tape it down straight. Avast, me proud beauty! When gluin' t' cone together, matey, 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. Arrr! MAKE SURE THE BALANCE POINT IS AT THE MARK IN THE INSTRUCTIONS! Since thar are no fins t' correct t' flight, matey, matey, you have t' make sure that t' CG location is correct.

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

Flight:
T' recommended motor is a B4-2, shiver me timbers, arrr, but I flew mine on a B6-4 (all I had in t' B class). Ahoy! Well, blow me down! T' prep is unique, shiver me timbers, because t' motor is so far forward o' t' base. Avast, me proud beauty! t' instruction recommend makin' extensions t' t' ignitor leads, but if you are careful, me hearties, shiver me timbers, you should be able t' hook your clips up without them touching. Well, blow me down! T' retention device is a small rin' o' BT-20 tied t' t' shock cord, arrr, me bucko, then slipped over t' motor. Avast! Blimey! Be sure t' keep your shock cord out o' t' way o' t' exhaust! No waddin' is needed, shiver me timbers, me bucko, shiver me timbers, especially if you sealed t' end o' your nose cone. 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. Well, blow me down! Remember t' warnin' about gettin' t' shock cord out o' t' exhaust? Well, matey, arrr, mine slipped down and on ejection was burned through. Aye aye! Well, blow me down! Motor case went that-away and T' Point came down like a batmitton birdie, shiver me timbers, givin' t' LCO a good look at how this rocket got its name. Begad! 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! Ahoy! Sure t' turn heads when you load it up on t' rack. Body wrap makes for a sharp lookin' model with minimum effort. Ahoy! Begad! CON's: Easy t' burn through shock cords. Can be a pain t' prep if you have large hands. Begad! Ahoy! Might be interestin' t' scale this up for 24mm.
