Ron, is the battery hold down set-up a known? It looks light duty...

Looks like the Gator Battery tray from F3AUnlimited, used in a modified fashion:

Battery tray is the stock one that comes with the kit. I use the same one on my Prolog and it's been there for the past year with no problem.

Right, it comes with the kit. I just glued in the composite cross-members and strapped to it with velcro. I wanted to be able to remove it for the inevitable repair to the landing gear block.

Grotto I ain't saying but I'm just saying that if it were me I'd put a couple if blocks in the structure for the UC and secure the tray in with 4 flat head screws. I've seen too many guys have Lipo's depart. Maybe I'm wrong it's just what I see. Thanks, Mike Mueller

This is an option for the Original paint scheme with the upgraded forward canopy and the forward sweep UC. In this pacgae you get both Canopy's the retro and the new one. Thanks, Mike Mueller

Ron,

I also have seen batteries jettisoned as the velcro hold downs failed. A couple of the guys flying large electric pattern use a single bolt and a securing plate.

Okay, thanks for the advice, guys. I'll probably follow mups suggestion with the flathead bolts.

We shouldn't forget that velcro does wear out and will require service, eventually.

The end corners are each held with a lap and a half of double sided velcro around the cross-members. The tray has a spine that runs lengthwise and locks into a built-up slot on the face of the cross-members, so it can only be extracted straight up. I pull-tested this to a few G's, but not to destruction, of course.

The batteries are held to the tray by surface velcro longways plus two double-sided velcro straps crossways for redundancy. I borrowed this method from JAS and it's worked well for me for many hundreds of flights. I'm not changing this part.

My previous two electrics have been conversions and this is my first one not designed to be oily. So in the past I've simply strapped the batteries down to a pipe floor rather than deal with a separate tray.
