But judging by what=99s written on them, it seems that the correct position of the FULL NOSE DOWN is that the Right Tab is up (23-25 degrees) and the Left Tab is neutral, which seems odd to me. It would appear that this position would cause some =9Cdistortion=9D to the tail .!!? What are everybody=99s thoughts on this?

Especially for those who finished building and are already flying, you probably already heard this question a thousand times, so please forgive hearing it once more. When lowering the Pitch trim tabs, both go down simultaneously and both reach the bottom limit at the same time and angle. But when they go the other direction, i.e trim tabs up, the right side tab goes till the limit but the left trim tab doesn=99t. It goes up slower than the right tab, then stops moving and even reverses the movement, not reaching the upper angle limit. Is this normal? I did check all the Pitch trim system components, and they all seem to be installed by the plans. Need help!

What causes distortion is that at one point you can have one tab trimming up while the other is trimming down. > On Sep 10, 2017, at 2:33 PM, Carlos Trigo wrote: > > Thank you Lew and Lenny > > I will try to follow the documents you both sent/pointed me out, and see i f I reach the right rigging. > > But judging by what=99s written on them, it seems that the correct p osition of the FULL NOSE DOWN is that the Right Tab is up (23-25 degrees) an d the Left Tab is neutral, which seems odd to me. > It would appear that this position would cause some =9Cdistortion =9D to the tail .!!? > > What are everybody=99s thoughts on this? > > Carlos > > > De: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@ma tronics.com] Em nome de Lenard Iszak > Enviada: Saturday, September 9, 2017 2:13 PM > Para: rv10-list@matronics.com > Assunto: Re: RV10-List: Pitch Trim tuning > > Tim has an excellent writeup on his site explaining the issue and how to f ix it: > > http://www.myrv10.com/N104CD/maintenance/20080622/index.html > > It just recently saved my sanity trying to align my trim tabs after a trim bellcrank rework. > > Lenny > > > On Sep 9, 2017, at 7:25 AM, Carlos Trigo wrote: > > I am now in the process of final installation and testing the Elevator Tri m system, and I could not find enough information on this. > > Especially for those who finished building and are already flying, you pro bably already heard this question a thousand times, so please forgive hearin g it once more. > > When lowering the Pitch trim tabs, both go down simultaneously and both re ach the bottom limit at the same time and angle. > But when they go the other direction, i.e trim tabs up, the right side tab goes till the limit but the left trim tab doesn=99t.
