I have used the foam puck battery stay system for years.
Works faster and better than the defacto velcro straps.

I have a strip of velocro on the pack and on the battery tray like always.

insert the battery all the way to the firewall and then compress and jamb the foam puck in there ontop of it. Holds, with pressure, the battery to the tray velcro. Has never moved a mm.

Some airplanes you need to put a "ceiling" on the motor box to hold against. Most have an "X" member up there already.

I can swap batteries in my Edge with gloves on. Wish all my planes could use this system. But many of my planes the battey is somewhere in the middle of the tray like it's suppossed to be. And then and there the strap system worsk fine (kind of hard to do with gloves on tho).
But if a plane needs packs against the firewall....this is the best system around.

Can you go into a little more detail on how you hold the front of the tray down or maybe even a picture?
Thanks

I just epoxied a piece of ply to the firewall that is 3/32" off the floor of the battery tray (thickness of the ply tray). You could always slot the firewall and make a "tounge" on the ply tray itself to lock it in. I tried to attach an image but got an error.

Does it matter which way the output gear on the rudder servo faces?

I wouldn't think so but IPS Motors says gear to the rear.

The 3DHS Build Manuals for the 51" Slick and the 57" Extra say the same thing...gears to the rear.

Ok. That's what I thought. And the ailerons and elevator have the gear to the front, right?

You can use the 57" Extra build manual to build the 58" Edge.

Ailerons and Elevator -- gear to the front is correct.

Ok thanks. I didn't know if that manual applied to the edge.

I had a chance to test the power system tonight! The Motrofly 4315-480 shows 1221 watts and 55amps with a 15x8 APC-E prop and 2x3s2800 30C value hobby batteries fully charged. I really had to hold this thing down to test...can't wait to have some decent weather for a maiden. Still need to fine tune the control surfaces and add dual rates, etc.

When you say gear to the rear do you mean that the servo arm should be towards the nose of the plane?

OK I just brought up the 57 build manual and gear to the rear seems to mean servo arm towards the rear. It must make zero difference as the 59 build videos say exactly the opposite!
