Geometry on spirit 2

zino · Thu 17. Mar 2022 17:31:36

Hi. I would like to ask spirit support team about geometry of spirit2. My question is, if is problem that in order to have 6° geometry on my trex 700n i must set to number 68 which i think is very low. What you suggest me for this? And if is problem what i suppose to do? Thanks

you need to move your ball links on your servo arms . If you are using Align servo arms I think the holes are too far out

Hi. I have align servos but my heli in trex 700n the first version. So how to do this? I mean servo arms are not connected directly to swashplate. Thanks

Any help from spirit support team?

you anyhow want to move the links on the servo horns one hole (or maybe even a bit more)... maybe you'll even have to change the servo arms. this will fix your numbers.

Hi. Thanks for the replay. If i understant well i must move the ball links more in so to minimize servo travel? Thanks

If Geometry value is small, mechanical resolution is small. To fix it, changing ball linkages closer to the servo center will increase it.
But it does not mean it is good way in all cases, because linkages could bind with frame or their angle is not perpendicular which introduces other problems.

It it is recommended that value correspond with what you will measure.

Thanks everybody for the response. I have allready move the ball links one step closer and now the geometry is much better. I have 6° with 90 number on the program which i beleive is ok. Before in order to have 6° i needed to reduce to number 68. Anyway now is look ok. Thanks
