Hello I hope someone with more experience answers your question , but for what its worth I still use Velcro to secure my batteries on most my electric models.
Regards Gerald

Hey Motorman, Just getting started on my SV11 electric posted this question in the ARF section no response yet. The instructions say to slide the ESC in from the front air intake underneath the battery box there is a solid wall at the front of this chamber just wondering what you came up with for this? As for battery mounting velcro on the right fuselage inner wall should suffice the outer force of spinning in a circle should be more than enough for it to stay put If there is any force to the inside something bad is or has happened. Thanks Walter

One question I had was how do you secure the battery? Not covered in the book either. They made a nice plywood chamber in there but what was the plan?

Thanks,
Motorman

Sorry I missed this. Since there are no air loads on the battery retention system there are any number of ways to do the deed:

* Both battery trays (upper & lower) have slots for Velcro straps. Since most folks use these it seemed pretty straight forward to offer that config.

* I am using a chunk of EPP foam salvaged from a computer package. It is a slab cut slightly taller than the battery chamber and stuffs in after the battery & under the hatch. The EPP expands into the lightening holes & such in the trays help retain it.

...and YES the manual should have shown this...

Seems like foam would block airflow and decrease cooling of all the electric ‘stuff’.

I’ve been using Velcro One Wrap to secure batteries. It’s pretty handy for other uses too.

Hi Jim
Point taken. If you are worried about battery heat, strapped batteries can have flow around one extra side. However, foam in this area does not restrict airflow to ESC or motor.

I worry about ESC cooling 1st, motor cooling 2nd. I do not actively cool the batteries, in fact Lipos do not mind warming up a little. Here "up nawth" we even have to seal off airflow to the battery when it gets cool out. Generally I still want a little free airflow above and below to premepts any super-heated dead airflow zones.
