RE: 40 size flight pack
After a little more research I see that is not possible to put together your own flight pack and save money over a pre-bundled set. I may however still consider the berg 4L. This particular pack will be put in a profile 3d plane where weight is a priority. 4 gram reciever vs 29 gram reciever.
The hitec bb servos weigh 8grams more than the futaba bushing servos. After 5 servos that saves me another 40 grams. Between the servos and reciever Im saving about 2.3 oz.
In my tight budget situtation I may end up going with whatever is cheapest.
