[NSRCA-discussion] Integral Landing gear

Sat Feb 27 06:05:04 AKST 2010

The final phase requires some sense of closure, which almost always neccesitates steering the conversation to the one topic upon which we have universal consensus.   

Ron is very very very old.

It is fun to watch these threads, but getting a little predictable..  

Phase A) It almost always starts with a simple, legitimate request for helpful information 
Phase B) for which a few useful answers are given.

But you know the wolves are out there circling. 

Phase C)  Finally one dives in and takes a bite with a facetious answer.  
Phase D)  Then the whole pack dives in and the fur flies everywhere.
Phase E)  Eventually things devolve into glow vs. electric 
Phase F)  Then Futaba vs. JR  (ya know the 14MZ has a built-in mix to mix out the effect of the steel plate)

who's next?

About 1/3 the weight of the angle plate.... You'll probably STILL make weight if it's glow-powered.   ;>)

I followed your instructions, but pushed the angle plate into the cabosil and let it cure before I read the part about the wax paper.  How much tail weight will I need to balance the angle plate?

Disclaimer:  This is intended as a humorous reply only. No actual angle plates or Integral Fuselages were harmed.
