Hi Dorsil
Suggest you read up on flying twins if this is your first. There is a lot of info in the Twin & Multi Engine RC Aircraft Forum. I built this kit about 3 years ago and it still is one of my favorites. A well engineered kit. Very accurate laser cut parts. I suggest using one throttle servo per engine rather than one servo and the long steel shaft that came with my kit. No easy way to correct something on the shaft due to an error or a crash. Most models, including mine, came out nose heavy. I used two .25 Magnum engines.
