OK guys, I'm finishing up my PML 1/4 Scale Patriot. Just one thing -- it weighs a ton more than it ought to.
The specs say that it weighs in at 50 oz., however, I didn't weigh the components before assembly.
At this point, it is (almost) fully assembled, and I'm (mostly) doing final sanding/finishing work -- and it is completely unpainted.
At this point, it weighs slightly more than 63 ozs, unpainted. The only changes/modifications I've made are as follows:
Added an Aero-Pack retainer (weight unknown, but seems very lightweight).
Changed out the elastic cord for the piston ejection for Kevlar. However, I weighed them, and they both weighed in at 1.6 oz.
Used 30 minute epoxy throughout. I have used approximately 4 liquid ounces overall. However, that is 'mixed' amount, and there was a huge amount of leftover epoxy for many of my 'gluing sessions', I would estimate actual glue used as 2-3 liquid ounces.
The parachute was also upgraded from 48" to 54". I don't know the weight difference.
The only other 'change' is that I did use expanding foam in the fin-can area to strengthen it for higher-power flights. I would estimate that I used less than 1 liquid ounce overall for this.
The model is the 38mm motor-mount version, and that's all the information I have.
Any ideas why it seems so heavy? Anyone have one they can weigh?
