Default Telemaster Twin Project

I have been thinking about a twin for a while now. I think this is a pretty simple build compared to some of the others I have seen here but I would appreciate any input because even though I have been reading everything I can find for the past couple weeks there are still some questions. I want to use Saito 65's because I have them already and it is my favorite 4 stroke. I do plan to have an onboard glow system. I also already have a Senior Telemaster kit that I would like to use. I plan on turning it into a FPV platform eventually for the fun of virtually flying from the cockpit.Some of the things that I have read that others say:
  • A twin taildragger is difficult for ground handling and should be avoided
  • Each engine should have 4 degrees out thrust (one left thrust and one right thrust)
  • Vertical stab and rudder should be enlarged
  • Tail moment (length) should be increased
All of these thing can be achieved with some alteration but how necessary would these changes be with this plane that has a very light wing loading?

The standard Telemaster is set up as follows:
Wing Incidence-4.5 degrees positive
Stab Incidence-2 degrees positive
Engine-3 degrees down and 0 degrees right
Should I maintain all of these specifications?

Below are some drawings that I have been working on to visualize the proportions and design change requirements. Thanks for any input........Mike in Michigan
