Hello Chip Hyde TEAM, (and any others who can help)

New Double vision owner, box arrives today. I've been flying for 3 years, typical learning curve from trainers to low wings to 3-D. I have kit built several and arf built most. My concerns are as follows:

1. I ordered the DA 50 and have seen many different threads on length of motor stand offs. Are the supplied ones from DA incorrect? If so, can they be cut down by carbon fiber blades, or do I need to order a different size from DA? Are the little circular plywood stand-outs just cut out from a 1/4 sheet? 1/2 sheet?

2. This is only my Third gas plane, both prior were flying bricks, an extra 300XS with a 41 cc US engine, and a Lanier Laser with some ancient 2.5. I KNOW BETTER now! What size gas tank should I run in the DV?

3. Is there room in the fusalage for a TME smoke system? If so, do you all feel that it's compromising weight too much (extra battery, tank, etc.)

4. What batteries should I use? NIMH? NICD? Mah ratings? (not too sure I want to spend the dough on the li-poly packs.. . . they've been nothing but temperamental in my electric outfits)

5. Are most people running nylon push rods for throttle control?

I know this is a heck of a lot of questions i know! Please help when you can, and thank you.
