I'm just finishing up a Hanger 9 Skylane that I picked up at a swap meet. It came with an OS 160FX rather than a gas or 4 stroke engine, and so is going to take some weight to bring the CG forward.

Will I be creating a problem by mounting the battery forward of the firewall? I've got a couple of options there. I can mount it to the engine box, or I can push it a bit further forward to gain some additional leverage by using zip ties to secure it to the engine mount. The engine is mounted at 90 degrees, which gives me a nice flat surface to support the battery and I can easily secure it.

In either event, whether I mount it to the box or the mount itself, it's going to take several strips of lead to complete the balance. Is there going to be too much heat under the cowl for the battery?

Thanks.
