Everyone,

    Thanks for all of the replys!   Talked to Tru-Trak this morning and this is what I found out.  First, the  pdf on the website for the -10 pitch servo is WRONG.  It is the older  version.  How about that for keeping things up to date?  According to  Zach at TT the hole for the elevator bellcrank is to be 2.5" up from the center  bearing AND .25" aft as was mentioned in an earlier post.  Hole size is for  an AN-3 bolt which should be a #12 drill.  ( Zach said of the hole size, "  we try to keep it around .200", about a #8" )  Well Zach's way off on that  one.  Tim posted earlier that the later versions of the torque multiplier  worked OK with the original hole location.  Zach said it should work at  that location as long as there is full control movement.  So here's my  dilema.  I drilled the hole assuming that the drawing on the web site was  correct.  I only drilled a guide hole (#30) though.  According to Tim  this location works fine and if there is plenty of movement in the servo to  allow full control movement I'll leave it where it is.  Does .25" make that  much difference?  If it's going to be a problem later I'll just make a new  bellcrank.  BTW:  The servo bracket for the pitch servo is included in  the fuselage kit from Vans....John

John, I as well as Tim installed the update kit later after the hole was drilled. It works fine. I would move forward.  Randy

One note, if I remember right the servo bracket that Vans provided did not work for me.  I had received another one with my servo that did work.  I got mine with my servo from Stein…..

I also used the original hole and it works great.

The bracket in the kit is not the same one as is need for  the new Torque multiplier, they sent me a new bracket when I got my servo's from  Stein and I used the original bracket to make a parking brake mount. I can take  pictures of the mount and servo if you want, or I think Deem's has some  excellent photo's on his site.

Yes, there is a revised bracket that you can get from TruTrak that

is different than at least the earlier kits got with the tail kit.

It just slightly moves the servo location.



Regarding John's question about the torque enhancer and the hole

location....it's hard for me to guarantee it'll work for you

no matter which hole you end up choosing, because there are now

3 variations of the pitch servo link that I know of...the one I'm

using now is the 3rd, and it's a wheel with a track kind of

arrangement.  I've always used the original hole and it has worked

perfectly for me.  But, I don't doubt that the other location could

probably work too, and it may even be more idea without me knowing

it.  In the end, you can probably make either spot work, and you

could even split the difference and put the hole in the middle.  I

really doubt the hole location is that precise...but this isn't

a recommendation to stray from plans...just pointing out that it

probably isn't that critical.



I guess if it were me, I'd wait to final drill until you get ALL

of the parts and are ready to hook it up permanently, AFTER you

have your elevator on and everything else.  Then you can get to

the part where you hook up the link, work the thing into full

pitch travel both directions while holding the torque enhancer close, 

and just see if both extremes would work.  If so, just drill away.



Don't sweat it too much...worst case, you just make a new bellcrank

and that part can't be too much money.

Thanks all for the advice.  From what I've seen on Deems' and Tim's sites 

this thing should fly ( pun intended ) as is.  And Tim's right, a new 

bellcrank is short money and very little time to make up.  Maybe I could 

exchange the old bracket for new bellcrank parts. Hmmmmmmmm.  Did I mention 

I'm cheap?  Another example of the wealth of info this board 

provides....john
