Default RE: Verbose Post Mortem contemplation of Edge 540 Debris pile" or "Getting the Love Back"

Thanks for the info...you're right...even if the receiver turns out to be OK...the key is enjoying one's self and that comes with the comfort of knowing that your equipment is 100%.

I immediately fell back on my avistar trainer to keep me enthused and work on getting the love back. I removed the receiver from the Edge and the battery pack and switch and installed it right away in the Av. I flew it for a couple of weeks and well, I must say, it was not glitch free.
There were several instances that a hard pull to vertical caused the Av to snap vertical much more abruptly than my senses were telling me was normal. So this receiver (in fact all my receivers) are going back to the shop. I checked my crank ratios on the Av to make sure I wasn't over extending the angles therein. Checked my epxo and all looked Ok so I will start /have started over completely.

Pretty hard getting the love back when the next ARF you step up to is so crooked. It should be obvious in the picture I posted at the end of my other [link=http://www.rcuniverse.com/forum/m_1050950/mpage_14/key_/anchor/tm.htm#1284962]post.[/link] Although
I should have put more info in there regarding those pics. One is of a level laying across the deck surface at bubble level
I then inserted the wing tube (which is frighteningly short!) through the entire depth of the fuse but extending as far to the right as it's length would allow. One can see clearly that the plane of the stab is way off relative to the wing tube...and the tube looks pretty parallel to the level and deck.

I think what I might do is stick a bunch of wet laundry in the dryer, stick the hose in the fuse and steam the fuse to soften it, and then carefully block it up and twist it straight and let it cure.

Now I have to ask though, had I been smart and slid the wings on dry, and discovered the axis of the two tubes to be so far off, would it have been practical to call the distributor, pack it all up and ship it back? Fixing the problem with an ARF is easier than building an entire plane, and A LOT easier than the trouble of returning it.

So in your opinion a pull pull is preferable to a FG pushrod and bell crank? I will say "old" technology is not necessarily bad technology...especially when it endures the rigors of time. I would imagine that Pull Pull technology is not much newer...but when one has a choice...what has proven to be the preferred method?

I really liked the idea that everything was solid rod all the way from ONE central servo and the crank creates a solid link between the two elevator halves and removes the hassle of matching the two and keeping them matched at all times (electronically).

Cheers!
