For those with or are knowledgeable about the
RV8, would you recommend batteries (2xPC680) in the rear or on the firewall
assuming renesis engine with a wood prop.
Hi Greg,
I've done it both ways with O-360's and heavy props, and
both have advantages. The last
RV-8 had an O-360 with C/S prop, and I put one PC680 on the firewall. That
puts the plane at the forward CG limit when solo, which is great for carrying
passengers and baggage, but not so great for fun solo
flying.
There's a lot of room for variation in installation
weight, but a Renesis with a wood prop certainly could (should) come out
lighter than an O-360 with C/S prop. As long as you beat the weight by
enough to allow for a second battery, then you can certainly put the batteries
on the firewall. Some people are putting batteries in the bottom of
the front baggage extension, just to get them off the firewall, and out of the
heat, so that's another option.
Before you close up the floors, it might be wise to leave a
wire run available for a rear battery, just in
case.
Cheers,
Rusty
