I was looking at the e-bay price where they are selling the 3200's for $35 and the 4000's for $70. Your price for the 3200's is slightly higher and for the 4000's slightly lower.

At $35 the...

Their price does not make them conducive to buying and testing. They charge twice as much for a 4000 than for a 3200 and most people find the 3200's adequate for their needs.

As far as I know all 17.5 turn brushless are stock certified as it would not make sense for a manufacturer to make a non stock 17.5 turn brushless. Who would such a motor compete against?

Yep, they definitely do not have hard cases. I run them in a 1/8th scale buggy and thus need 2 of them to fit into a single battery tray.

I have not had a chance to test the Yeah 4000 LiPo's to see if they meet their specifications, and unfortunately I probably won't considering their price and not being a sponsored tester.

Actually for that voltage drop test I discharged them both at 60A, which is pretty close to 20C for the 3200's and either 15C if you rate them at 4000 or 17C if you think of them as 3500's.

I wish Yeah would rebadge them as 3500's, not 3600's. I know 100 ain't much, but their 3200's (I have a total of 8 now) all supply a little bit over 3200 mAh and the rebadged 4000's (I only have 2...
