Hi All,

I'm collecting components for a new trex xl cde. I'm currently looking at a trade between motors and whether to go 3cell or 4cell on my lipos.

What are the constraints? I'm looking at the NEU 1105/2, 1105/2.5, and 1105/3. They have KV ratings of: 5200, 4000, and 3500 respectivly.

...yes there are other motors out there but I'm trying to understand the relationship between KV and lipo cells here.

Is one KV rating better for 4 cell? Can I go with the 1105/3 with 3cell then upgrade to 4cell when my skill level increases??

My key interestes are flight longevity, then 3d power. I'm not doing 3d yet, but I hope to be flipping etc. next summer.

thanks, in advance,
Cheers,
Leslie
