Default to Gain or not to Gain?

hey freaks, i have a DX7 with the 3gx setup v2.1 on my trex 550e FBL. on my gain screen on the tx i have 77% at 0position & 77% at 1position. in the 3gx software screen under settings display my gain reading is at 51%. i remember on finless's video he said that if you used a futaba tx the gain was exactly what it read ie 32 gain is 32 gain, but on other tx's you had to use an equation to figure out what it was ie 70 would = 30 or 32? is this what i'm seeing here?77 is actually 51. another reason i ask is, before i raised my tx gain to 77 it was like 70 which was below 50 in the software screen under rudder gain the heli was acting a little weird. was this rate mode? i raised the tx gain to 77 = 51 in software rudder gain. is this heading hold?

I think your dx7 is like my dx8 where the scale is similar to futaba -100 to +100. If so, you want to put in +35 for heading hold as a starting point (per the manual). I'm flying with my gain set at 36 on the TX

if your scale is 0 to 100 like the dx6 then start at 70 on the TX

when i was flying my dx 7 with multiple 3gx units my gain was -100 +70. never touched the negative side, and made only small changes to the top. my 9503 uses the same settings.

The old DX6, DX7 and 9503 should be about 70

The newer DX8 and DX7S use the Futaba scaling and should be about 35

It's nice that the industry is standardizing but it leads to confusion in the short term
