Hum...

The question is:

CG is 3 cm below IMU

or

IMU is 3cm above the CG ?

I always struggle to understand

For GPS it's minus so it must be the same for IMU as CG is below both

I will take some pictures soon of how I connected the zenmuse to the frame.

Here is a short video of one test flight I did today.

I have already to many 4s lipo, would be a shame to buy another round of new batteries. if not 4s, what about 8s ?
You can always split a 4 cell into 2 two cells and solder each of those 2 cells to another 4 cell to get two 6 cells. Lol ... that has a high potential for confusion. As long as the packs are of the same type, this works nicely. You just use 3 identical 4 cell batteries to get two 6 cell batteries.

Hi.
I have my z15 to ride my heli.
My question:
you can mount the z15 in the front of the heli? or must be under?

Thank

Yeah, I know what you mean. On that note, it suprises me how many s800 owners are using "cheapo" lipos. I won't name any particular battery brands, as I don't want to rub any one wrong, and I think we all have a notion of what batteries fall into this category. For my s800, I have 2x 6200 mAh 35C Neu Energy batteries. They are premium batteries, which, of course, I had to pay for ($290 for both, which I don't think is that bad for premium lipos). They are lightweight, compact, have a long lifespan, and are very reliable. If I didn't go for these, I would have gone for either Thunder Powers or Hyperions ... period.

How about this for the s800 17 mins flight time fully loaded and about $150
