I am confused about the balance of the elevator. The plans say a max of 37.5 in/lbs down. Without having the elevator connected to the controls and trim tabs not connected I measured the balance. It is about 15 in/lbs down. So my questions are:

What is the minimum?
When should it be measured? I am assuming after all rigging is complete.

Any suggestions would be appreciated.

I sent a note to Van’s awhile back on elevator balance. When building my RV-8A the instructions told you to trim the counterbalance weights until the elevators were balance, as in statically balances so that the elevators stay horizontal with no force acting on them. The weights in the RV-8A are much larger than the RV-10.

Building the RV-10 it is obvious that to achieve this same balance requires much larger counterbalance weights than that supplied with the kit. Van’s reply to my question about this was “the elevators will hang trailing edge down” and that there is not need to add the weight to make them statically balanced as in the RV-8A.

Recommend just building as per plan.
