Hi, the v-one 707 gauge file is found on avsim...I just downloaded it yesterday for the 707 bought during the latest sale. A question I have on this is with regards to the CG modification to carry out in the aircraft.cfg and reading some other posts on this whether you should do it or not.  In any case I did the modification and on t/o the gauge is showing a -16.7deg of trim required. This is completely outside the green t/o range on the trim wheel...so is this correct and the ones who use the gauge have modified the cg to 9 or left it at the default -9. Thanks for assistance.

The readme has an error in it. The gauge line should be:

empty_weight_CG_position = -9, 0, 0

Sorry for any confusion  :(
