PML Standard or LOC Custom 4" Patriot - All the custom laser cut components are included in the box to build it strong and legit! This is one of the LOC-CUSTOM SERIES of kits. Featuring factory pre-slotted airframe, through-the-wall fin construction and high power motor capabilities. The Patriot is a fantastic jump into high power with your choice of airframe materials! If you're looking to go big, add a LOC Removable Nose Weight System (RNWS) OR the PML Intelli-cone to make weight cartridges of your choice to balance the use of heavy motors. Adding/removing nose weight at the field has never been so easy! Build it traditionally or assemble the fin can outside the airframe, knife the areas between the slots and slide it up--your choice! 

LOC trim features a 38mmt and includes 1/8" birch ply fins, 36" LOC parachute, standard rings, rail guides and vinyl decals. Well balanced up to 38mm 3 grain motors. A scale height of 53.5" tall!

The PML trim comes with Phenolic airframe, G-10 fins, rail guides and a decal sheet. Recovery components include a 42" LOC parachute and a Kevlar tether. Slightly longer at 58" in height! You can easily upgrade to the 48" multi-panel Dura-chute if you choose! 

NOTE: the PRE-GLASSED PHENOLIC AIRFRAME version is made to order. Please allow 10-14 days before shipment.

Leo ★★★★★

Wasn't sure what to expect from a kit with pre-slotted fins, but everything lined up square on the first try. The laser cut components are thick and sturdy, not the flimsy stuff I've gotten before. Flies straight and stable on a G motor.

Michael I. ★★★★★

The laser cut parts fit together so cleanly I barely needed sanding before gluing. Everything for the build came in the box, which saved me a second order. Flies straight as an arrow on a G motor.

Hazel L. ★★★★★

Didn't expect the fin slots to line up this cleanly straight out of the box. Everything needed to build it legit is included, which saved me a trip to the hobby shop. Flies dead straight on a G motor.
