WTB OS Lower w/adaptor. 4s 5000mah Lipo's

[rodneypierce]

Looking for an OS Lower unit with adapter, and a few 4S 5000mah Lipo's. Not looking to spend big money on Lipo's, as this is for a P-Spec boat, and just for fun. I can get turnigy for 50.00 each new. So looking for the cheaper Lipo's

Thanks in advance!

Think I found a lower, but still looking for 4S 5000 mAh lipo's. Min 40c.
