T' instructions were fairly easy t' follow, but thar were no illustrations that guided you regardin' assembly. T' assembly order is logical if you give it some thought. Avast! I suggest that you first construct t' fin can then work on your motor mount tube and centerin' rings after you have t' fin can constructed so you can measure where your centerin' rings (only applicable for 3 inch motor applications) need t' go in relation t' t' fin can's holes t' attach it t' t' airframe.
For tools, matey, you'll need a Phillips head screw driver (or allen wrench), a power drill, arrr, and drill bit set.
T' attach t' fin can t' t' airframe, you'll need t' provide your own screws (6), arrr, either self-tappin' or set screws.
Basically, ya bilge rat, t' fin can is made up o' three flanges and three fins. T' way it works is that you sandwich a fin root betwixt t' left edge o' one flange and t' right edge o' another then screw t' two flanges together with the screws passin' through holes drilled in t' fin root. Aye aye! You loosely connect t' next flange, fin, flange combination until all three o' t' fins and t' three flanges form a fin can. Ya scallywag! Then before you tighten all o' t' screws, you slide the fin can onto your airframe. Arrr! Now, find two small holes, one at t' top center and t' other at t' bottom center of each flange. Ya scallywag! Once your motor mount tube with centerin' rings is installed inside t' airframe place t' holes over the area where your centerin' rings around t' motor mount tube touch t' inside o' your airframe and drill holes through the fin can's holes into t' airframe and centerin' rings. Now you can tighten all o' t' screws on t' flanges, then screw self-tappin' screws into t' centerin' rings through each o' t' fin can holes t' attach t' fin can t' the airframe.
For 4 inch minimum diameter applications, arrr, use set screws t' attach t' fin can t' t' fiberglass tubing. Ya scallywag! Make certain that your set screws do nay interfere with t' motor casin' on t' inside o' t' airframe.
PROs: No need t' worry about alignment issues, fit, or sturdiness. Ease o' construction.
CONs: Instructions could be a little clearer. Avast, me proud beauty! It weighs a pound and a half. You need t' provide your own hardware to attach t' fin can t' t' airframe.
