Luke,

I already added the traingle stock behind the firewall. I put four pieces behind it. One just under the top brace, one on the bottom, and one on each side. I have learned the hard way when it comes to firewalls on the majority of ARF's. Although VF's seemed more sturdy than most I have encountered, I didn't want to take any chances. I will probably end up throwing a few strips of 'glass back there too. The weight isn't a huge issue considering the Saito 120 that you and I are running.

Where did you mount your throttle servo? Can you post a couple of pics of your throttle servo? I would like it to stay in the servo tray to help out with the balance.

Thanks again for your insight.
