"The most innovative rockets I saw at the 1995 RCHTA show were the square laser cut models from SDI." 
"First a warning: just as with small die cut balsa parts, some of these parts are very fragile, and easy to crack while separating them from the scrap." 
". . . this kit almost snaps together. All the parts fit perfectly with no sanding or other fudging." 
"This kit has more parts than anything I've built in a long time, 50." 
"Heed the warning about excessive pressure cracking body parts." 
"Even the motor retainer is a laser cut piece of teflon that twist locks into the back of the model." 
". . . using an A8-3 for the maiden voyage. The model lifted off nicely, for a straight, but low flight." 
"I have reservations concerning the materials, I would have preferred aircraft plywood . . . to increase the strength." 
"It's very different in assembly, yet still quite easy to assemble, and all the parts fit perfectly."
