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

Construction:
Kit comes with a pre-slotted main airframe, arrr, shiver me timbers, arrr, a pre-slotted boat tail and a plastic nosecone. Begad! Begad! It has 4 fiberglass canard fins, me hearties, and 4 fiberglass main fins. T' piston ejection kit comes with a piston body, piston strap, me hearties, slotted bulk plate and metal "D" ring. Begad! Other items include a nylon chute, me hearties, 29mm motor mount tube, notched centerin' ring, nylon shock cord, matey, 1/4 inch launch lug, alignment ring, 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, me hearties, matey, and everythin' went smoothly. Begad! There isn't any templates for t' fins, me bucko, but one can be made easily. Ya scallywag! Blimey! Before I epoxied t' canard fins t' t' main body tube, matey, 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. Minor sandin' had t' done t' t' centering rin' and nose cone, me hearties, but everythin' else fit perfect, me bucko, includin' t' piston. Ya scallywag! 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, shiver me timbers, t' tubes have t' be sanded lightly with 320-400 sandpaper. Avast, me proud beauty! I used an electric pad sander on t' nose cone t' remove the lines. I held t' sander upside down betwixt me knees, arrr, and held t' nosecone lightly by both ends on t' sandin' pad. Aye aye! Blimey! It spins slowly and gives a nice finish. Arrr! Blimey! Paintin' was done by usin' and Ace Hardware brand o' gray primer, and Rustoleum gloss white. Ya scallywag! T' rocket has a number o' decals. Blimey! Blimey! T' instructions easily show t' placement. Begad! Blimey! 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. This small rocket can be used for a Level 1 Cert ! I flew it on an G-80-7. Avast! Since it uses a piston ejection system, ya bilge rat, arrr, no waddin' is needed. Aye aye! Begad! How easy can it get? Just install the piston and straps, folded chute and install t' nosecone. Begad! Done. Begad! On t' G-80 I wrapped t' aft o' t' motor with 3/4 inch maskin' tape t' build it up about 3/16", arrr, and then put vertical tape strips on t' motor until it fit snug in the motor tube. Blimey! Begad! T' launch was absolutely straight and fast. Blimey! It went about as high as a person with hawk deadlights can see. Arrr! Ahoy! Ejection was at apogee. Blimey! Well, blow me down! T' piston ejection system worked perfect.

Recovery:
T' piston strap and shock cords are standard PML nylon. Avast, me proud beauty! Arrr! Assembly is simple. T' rocket comes with an 18 inch nylon chute, shiver me timbers, matey, and it drops a little faster than you may want, but t' rocket is very durable and you don't have t' chase it down too far. Ahoy! No damage was done t' t' rocket. Begad!

Flight Rating: 5 out o' 5

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

Overall Rating: 5 out o' 5
