Default Need Help With New Airfield p51 1100mm Mustang

Just picked a new Airfield p51 1100mm Mustang. Trying to figure how the battery is supposed to go ? Does it go in the middle of the cockpit area? There is some Velcro stuck on the bottom towards the back and servos is that for the battery or the receiver ? Trying to figure how to secure battery so it does not slide around. Can anyone help by telling how you have your set up for proper cg? Any pictures. Thank you !!

Is this a "Foamie" model?

What needs to be done is to first install everything except the battery in the model. That would be the motor/esc/receiver/servos/landing gear, everything.

Then place the model on a cg balance system and place your battery on TOP of the fuse, moving it back and forth until the model balances at the specified cg point.

Now, you've got an indication on where that battery has to go, inside the model. So, stuff the battery inside, with temporary bits of foam rubber or what ever at roughly the same location as before.

Once you've got the battery location identified, its time to properly secure it for flight duty. Velcro works well in this type of application. But Velcro doesn't adhere well to foam. What I've done is epoxy a thin sheet of lite plywood to the foam. That thin lite ply should be the same width as your battery, and three or four inches longer than the battery, if there is room. Then cover the area where the Velcro for the battery is going with a very thin layer of yellow glue. Let the yellow glue dry overnight. The yellow carpenter glue provides a very solid surface for the Velcro to stick to. Without the yellow glue, that Velcro can let loose, causing all sorts of problems while trying to remove your battery. Then put a piece of Velcro on the thin ply, and secure the battery to that Velcro.

You don't need a lot of Velcro for this purpose. A long piece on the sheet of lite plywood. And a couple of pieces about 3/4 inch wide under the battery.

And, be sure to mark the proper battery location with a marker pen!

Hope that helps.

Like Denny says, make a wood battery tray, might want to glue some blocks of bass wood to the foam, then screw the tray to that, that will allow you to remove the tray if you need to get to the electronics, use velcro straps, also, you might want to give your plane about 3 degrees of down thrust, people are having a issue with that plane and the durafly plane wanting to pitch up under power.

I read that when the canopy hatch is put on it locks the battery in place and the CG is good if you use the recommended battery size. My FMS p 51 is the same idea it slides into the hole and the canopy keeps it in place. Took a few flights for me to trust it, but it does work. One guy got brave and cut the forward part of the top fuse and made a battery tray.
Look at post#299 and you can see what I mean.

Nice setup Chellie, but it won't work for this plane just a hole that you slide the battery into.

DO NOT PUT IN FULL SIZED VELCRO HOLDDOWNS.

I found out the hard way how difficult it can be to remove a battery in a small compartment. Better to do 1" X 1" pieces every 2". That holds great. But allows easy lift outs as each piece is pulled loose one at a time.

Yeah, been there, done that. And trying to remove a battery with a full length of Velcro under it can be a real .

Also, for the Velcro that is stuck inside the fuse, be sure to pre-coat the balsa or plywood sheet first with a thin layer of plain old yellow carpenter glue. Otherwise, that Fuselage Velcro can come partly loose, and make it just about impossible to get the battery out. In a tight battery compartment, you will learn new cuss words! (Don't ask!)
