I have been studying options for an electric conversion and would love some feedback if you have any. It is looking like a 6S setup, and probably a Hacker A50. I'm a little confused because people are using the same setup on "50 size" planes like the Sebarts, at only 6lb but using small props. However Sebart suggests 6S for the 125-size Mythos, so maybe it's based on new technology. 6S is also used on ~8lb planes by 3D Hobby Shop and the like, so that's where I came up with this (also some experience by others with electric Venus planes). I also came up with 6S because I have 3S packs to run in series. This will be a backup plane when my 2M is ready, so I don't want to buy 4S/8S packs that would only be used in this one airplane.
My research has pointed me toward these motor combos:
Hacker A50-14S (425kV) and 15x10 (63A/1350W), 15x12 (71A/1500W) or (16x10 75A/1570W).
If the calculator is right or on the conservative side I could try a 16x12 (84A/1750W) or a 17x10 (87A/1800W).
Alternate is a Hacker A50-16S (365kV) and 17x12 (71A/1500W) but it seems I'd need this much prop for power and speed but can't fit bigger, so that's a concern.
The other alternates are the RimFire 1.20 (462kV) (seems like it would turn a 16x8 similar to the 120AX or 16x6 or 15x10 similar to the YS110, but that wouldn't make best use of electric efficiency I thought). It's also a heavier motor, but that usually means better capacity to handle heat.
I suck at making decisions.
