APS leonardo mid drive

I happen to be on alien power system site looking at some motors and stumbled across this which i have never seem before

It appears to be some sort of cradle to mount RC motors as mid drive, No idea on the reduction or anything else for the price I would hope it's more than just a mounting cradle

Curious to see if anybody else has seen these,
Looks to be a pretty trick set up for those of us without welding skills that want to experiment with something different

Its not very impressive to see on there web site when you go to the page for this mid drive kit it only shows a drawing and states sold out. Hard to believe they would actually sell out before having a real photo of the assembly for sale. Big bucks also, seems like wishfull thinking at first look
