HI Arch
Thank you very much for the helpful response and quick one to boot! - I will certainly take you up on PM'ing you, as I ask lots of questions before I make a cut

In my question about the DEPS, I guess my main concerin at the moment is the required force to move the currently installed setp back and forth ( carbon tubes not attacehd at Elevator end, but are connected to ball link at fuse, ready to take attachment to servo in carbon servo tray. Since I also fly helicopters, I am used to very, very smooth pushrod movement to my Heli tails, which I make sure always happens. I am concerned with the amount of force necessary to move the DEPS setup and since the fuse is all completely sheeted, I am a little worried I will not be able to make any changes without cutting a hatch or two in the botoom, fixing/replacing to try to make smoother action. THe original owner I bought it form , said that the carbon fiber tubes in the original DEPS setup were no longer available and the tubes he used for the pushrods are clear plastic. I intend on using a high quality digital servo to drive, but I hope it could support minor elevator changes that I am sure will be needed. An additional concern is that the DEPS pushrods exit the rear fuse leaving what appears to be a significant run of unsupported tube to the anticipated elevator hook up - wondering about the flex here as well. I appreciate your expeience and guidence here - I am reading the assembly manual to learn more as fast as I can

As for the CDI, do you mean electronic ignition for the YS? - I have never heard of this, for a glow motor. I have a few ships that run GAS, but I will certianly look into the CDi given your suggestion. Is the 170 prone to stopping in flight, etc? - I fly YS 2 stroke Heli motors and love them. Never had a YS 4 stroke yet, although I have heard all the talk about them being either awesome of tempremental. I am going to send my 170 back to YS performance and have them give it new bearings, diaphram, etc. since it will be a while befoer I get the VF3 ready, and I beleive the 170 in my setup has been sitting for ~ 2 years

Also, sounds like Monocoat works on the entire ship! - glad to hear this. There are a few "retired" national level capable monocoaters in my club, I might attempt to bribe them to cover my VF3 for perhaps some computer help, begging, etc.

I really appreciate your help - I will be in touch again!
