on the stand offs, If you order the DA from Tom it will come with 3" stand offs. so a 1/4 inch plywood or hard wood shim will get the job done. If you order direct from DA, simply ask for 3" standoffs. They Will exchange them at no cost.

the choke servo is an item of preference. what ever works for you.

servo arms, air wild MLP arms or the SWB arms are the ticket! order 1.25" arms for ailerons and elevators. and a 3" double for the pull pull.

here are some pictures of my install.
