RE: RC Guys Super Decathlon coming
The picture on that site is of a model that has no elevators or rudder. It takes nothing to stand a model on its fin when there's no rudder or elevators.
If you want to stand it up the way the photo shows, you NEED to read what I wrote.
Take the time to read it. It doesn't take a genius, and it's not hard to do.
The two by fours serve two purposes, for two reasons. 1. They hold the elevator and stab in one straight line. 2. They act as standoffs, holding the elevator and stab up off the ground, far enough that the rudder doesn't hit the ground, or at least far enough that the rudder doesn't bust off by downward pressure on the tail, since: 3. The model is standing on its tail to position the firewall level, because: 4. That's how you mount a gasser onto a firewall.
PM me if you need to, Paul, and I'll give you my phone number. I can describe it easily. It's really easy to do.
