Brief:
T' Bull Puppy 2.1 is a single stage, shiver me timbers, Quantum tube rocket with piston ejection.

Construction:
Kit comes with a pre-slotted main airframe, me hearties, a pre-slotted boat tail and a plastic nosecone. Well, blow me down! Blimey! Blimey! Blimey! It has 4 fiberglass canard fins, ya bilge rat, and 4 fiberglass main fins. T' piston ejection kit comes with a piston body, piston strap, slotted bulk plate and metal "D" ring. Other items include a nylon chute, 29mm motor mount tube, ya bilge rat, notched centerin' ring, me bucko, shiver me timbers, matey, nylon shock cord, ya bilge rat, 1/4 inch launch lug, me bucko, alignment ring, me hearties, me bucko, decal sheet and instruction sheet.

T' instructions are very easy t' follow with lots o' illustrations. Avast, me proud beauty! I used the instructions assembly order, and everythin' went smoothly. Begad! There isn't any templates for t' fins, me hearties, but one can be made easily. Aye aye! Ahoy! Before I epoxied t' canard fins t' t' main body tube, shiver me timbers, I used a door frame t' make an alignment mark at the bottom o' t' tube for when I installed t' boat tail, which houses the main fins. T' fins need t' be sanded with 220 grit sandpaper t' scuff them for paintin' and t' round t' edges. Ahoy! Minor sandin' had t' done t' t' centering rin' and nose cone, but everythin' else fit perfect, includin' t' piston. Well, blow me down! I used Ace Hardware's 5 minute epoxy first t' adhere parts, and then used t' 90 minute for additional strength and fillets.

Finishing:
As with any Quantum tube rocket, t' tubes have t' be sanded lightly with 320-400 sandpaper. I used an electric pad sander on t' nose cone t' remove the lines. Avast! Begad! I held t' sander upside down betwixt me knees, shiver me timbers, and held t' nosecone lightly by both ends on t' sandin' pad. It spins slowly and gives a nice finish. Ahoy! Paintin' be done by usin' and Ace Hardware brand o' gray primer, and Rustoleum gloss white. Well, blow me down! Begad! T' rocket has a number o' decals. Arrr! T' instructions easily show t' placement. Ahoy! When completed this rocket is VERY sturdy and looks impressive.

Construction Rating: 5 out o' 5

Flight:
T' Bull Puppy 2.1 will fly on anythin' from an F-20 t' an H-70. Begad! This small rocket can be used for a Level 1 Cert ! I flew it on an G-80-7. Ahoy! Ahoy! Since it uses a piston ejection system, no waddin' is needed. Avast! Ya scallywag! How easy can it get? Just install the piston and straps, folded chute and install t' nosecone. Ahoy! Done. Ya scallywag! Aye aye! On t' G-80 I wrapped t' aft o' t' motor with 3/4 inch maskin' tape t' build it up about 3/16", shiver me timbers, and then put vertical tape strips on t' motor until it fit snug in the motor tube. Aye aye! T' launch was absolutely straight and fast. Avast, me proud beauty! Ahoy! It went about as high as a person with hawk deadlights can see. Ejection be at apogee. T' piston ejection system worked perfect.

Recovery:
T' piston strap and shock cords are standard PML nylon. Ahoy! Avast, arrr, me proud beauty! Assembly is simple. T' rocket comes with an 18 inch nylon chute, ya bilge rat, and it drops a little faster than you may want, me bucko, but t' rocket is very durable and you don't have t' chase it down too far. Well, blow me down! Ahoy! No damage be done t' t' rocket. Avast, me proud beauty! Avast!

Flight Rating: 5 out o' 5

Summary:
For someone new t' HPR, or even t' experienced modeler, arrr, this is a great rocket. It's small, sturdy, doesn't take a lot o' talent, material or time to build, shiver me timbers, and just looks great. Arrr! Blimey! I can't think o' any cons.

Overall Rating: 5 out o' 5
