All,
This is my first build and radio program and i thought i got everything right but my maiden flight today was a backwards affair. I had issues with the blade tracking from a previous post and resolved those without any real issues. I ended up with a 5point curve of:
Normal: -7 (low stick), -4 (1/4 stick) +0 (mid stick), +5 (3/4 stick) and +10 (high stick)
IdleUp1: -6 (low stick), -2 (1/4 stick) +7 (mid stick), +8.5 (3/4 stick) +10.5 (high stick)
IdleUp2: Due to my skill level (None) i copied IdleUp1
Throttle Hold: Max Negative (low stick), 0 degrees (mid stick), Max Positive (high stick)

So i spool up motor sounds great, blade are tracking perfect for woods and not much is happening about mid stick so i give it just a little more juice an i see the skids start to flex out. I said WTF and took it to the bench. Everything is reversed. All my pitch settings above are reversed now. High stick in NM is -10, Low is + 7 etc and IdleUp 1 High is -10.5 and Low is +10.5. What the heck did i do wrong? I changed nothing from my initial settings? Must have had to much coffee or something this morning. Thanks for any advice whether i made an idiot noob mistake or not.

not sure about the DX7 but on the futaba the swash setting for ccpm the pitch go's +50
i had to turn it down to -50 so the pitch would go the right way try that out....................

not sure if you noticed this or not...on the mini titan the blade pitch increases (+) when the swashplate moves down. blade pitch decreases when the swashplate moves up (-). this is due to the leading edge control on the blades. make sure your swash moves properly. other than that i'm out of ideas.

In the settings on the DX7 you have to move the pitch one to -60. It starts out at +60 as the others do but needs to go to -60 which is in effect reversing the pitch movement. Hope I have explained that ok as I am a novice myself.
