EZI 65 Build Tips

EZI 65 Build Tips

Hi Guys,

I'm building a LOC EZI 65 and I was wondering if you had any advice for me.
 I am using 3 centering rings and I am leaving the rear one off until I get
the fins on.  I am either going to  fillet the fins where they meet the
motor tube and the inside of the tube ( as well as the usual ones on the
outside)  Or instead I was thinking that I could epoxy some pieces of 1/4"
dowels where the fillets on the inside would go.  Epoxy is great stuff, but
it is brittle, and heavy.  I used the dowel trick on an Iroc and it seemed
to work well.  Tell me what you think.

I recommend using a longer motor tube.  That way, you can use longer
54mm motors including hybrids.  Also, chuck the LOC shock cord mount, in
favor of an eyebolt mounted into the forward centering ring.

(yet even more snip of some great motor-tube advice)

I see a rocket, here, that is either way-over-built or your building it
for L-motor minimum. ;^)

The back-building technique works beautifully. It adds tons of
stregnth. But, one of my favorite flights that I ever saw was a
back-built STOCK EZI-65 on a J800. It was a pretty cool flight.

The EZI is a great kit, It's already designed to take big motors
without needing *extra* stuff done to it.

Don't worry about it. Just finish it and fly it. It flys great!

Have fun,

Mark
