Projects Derek's New Project: Un-named 3D Plane

[Blackwarrior]

Unfortunately, Castle doesn't list a surge (or burst) rating for the Phoenix Edge 80HV. It's quite possible, unless I hear otherwise, I'll order a 120HV. It's the next size bigger than the 80HV.

Yeah it just says that 80 amp is the maximum current rating, hopefully someone will verify this, but I wouldn't use it especially of your doing 3D stuff...

Your 2- 6S batteries in series or parallel ?
Parallel would only give you a 22.2 Volt source pushing your current to 121Amps.

Never mind, "but since I want to run a 12S battery setup on this plane..."
Found my answer.

I am a little with the LG answer but at the leading edge of the wing is best! Trust me I have been laughed at for my landing gear that is too far back and I nose over on take offs and landings!

 

[Derek]

I've got the landing gear placement all marked out on the belly of the plane now.....just at the leading edge of the main wing.

Now, I need to sort out which ESC is going to work. I may just end up getting the Castle HV 120, just for that added reassurance.

Does no one else have an opinion? I'm guessing that the 80HV will be enough but I don't want to get the 80HV and burn something up. On the other hand, I don't want to spend the money on a 120HV if the 80HV will actually work.

Your motor is rated at 75A, so the 80HV Edge will be enough. It can run a continuous current of 80A and way more as a Burst.
The batteries will depend on the real C rating, not the sticker rating. Even If they were only 25C thats 80Amps.
So you should be good to go.

Thanks for that, Lee! How do I find the "real C rating" instead of the sticker rating?.

In regard to the C rating, I've learned my lesson. Initially, I bought some 20C batteries because they were cheap. Then I start flying better and flying harder...full throttle vertical climbs for excessive periods of time....then I noticed some puffing. Hmm, not good!!! Then I started researching more and learned more. Now, I spend the extra money for nothing less than 35C batteries. I haven't puffed a battery since.

Excellent news, that will save a bit of cash Derek..

The real C rating is only revealed, once you buy the battery and test it your self.
Justin on RCHN did a review if packs last week. He talks about the real C rating.
Only packs he said had the same as the stick said was. Spyder packs from ProgressiveRC.
