Battery holder for P47 3Dlab plane

thingiverse

I have a 3dlab P47 and wanted a better battey holder, also I figured I could use it to adjust the CG. Both holders have a lower recess to allow the batteries to be strapped in with a velcro strap. Once secured the holder can be locked in place in various positions. I hope this will give a non moving CG weight. May fit other models, you can just adjust overall size in slicer, or if wrong height/width for you use the flat one. Two are 'cage' types, one has notches on one side so you could use a side bolt to secure it. Otherwise use one of the bolt holders glued in place and the slotted strip (two slot sizes) as in photo glued to the battery holder of the plane and a suitable other point. The flat holder has two 2x3mm rails to glue to the sides so it slots in. I will be using this one as lightest of the two. My first attempt at designso hope it is of use. Other parts in the photos are cleats for control rods and a reciever holder for general use, I will do separate postings for them..
