Brief:
This is a sport scale rocket that features PML's new Quantum tube. This rocket
makes a good choice for the mid power to high power transition.
Construction:
This rocket has one section of PML Quantum Tube, with no payload section. There
are 2 centering rings made of sturdy plywood, and 3 G10 fins. There is a
plastic nosecone, but the only hardware included is the D ring used in the
piston. When both straps are tied together, the shockcord is about 12 feet
long.
The instructions on this kit are TOP NOTCH, as are all of PML's. The instructions guide the builder step by step with pictures and detailed descriptions. No templates were included, or needed with this kit because of the pre-slotted tube. This rocket goes together just like any other high power kit.
All of the parts fit together perfectly, which made it very sturdy. I added 2 part foam to the fincan along with the internal fillets to make this more sturdy. Two part foam can be bought at most hobby stores. Stick with the PML or Northeast Hobby Products foam.
Finishing:
Finishing this bird was an ease. The QT eliminates all need for filling tube
spirals, so a quick sand with 400 grit sand paper and it was ready to paint. A
couple coats of primer, then went over that with red automotive paint. Masked
off the fin and the top and painted red again. The reason I painted the red
again after I masked off the areas is if any paint runs through it will not
mess up the paint job, and the red coat seals the tape down. i then went ahead
with the brown and white and painting was complete. The only decal not included
for this was the white stripes that go up and down the sides. Call an
automotive or sign shop to get in touch with some of this. After that, a clear
coat was put on and the bird looked awesome.

Flight:
Well, PML reccomends every motor from about a F50 up to the J570. I have
currently flown this bird twice, both on G64-7's. These flights were both
atraight as an arrow to about 1200', and the 7 delay is perfect. The piston
ejection system eliminated the need for wadding, therefore preperation went
much quicker. For motor retention I used 4-40 blind nuts in the aft centering
ring, and a pair of screen clips to hold in the casing.
Recovery:
This rocket has the piston system, which consists of a bottom piston strap, the
piston, and the top piston strap. I replaced my bottom piston strap with Kevalr
for strength. This rocket comes down FAST. I have never seen a rocket fall
faster, but as long as you are dropping it on turf or a field you'll be
alright. If near cement, get a bigger chute. The first flight suffered no
damage, but the second flight inflicted minor paint cracking and chipping in
the fin area. This was because the rocket was spinning on it's axis during
descent.
Flight Rating: 4 out of 5
Summary:
This was a great rocket to build and fly. It is easy to assemble, and is a
great performer in the sky.
