Read the "All Amped Up" forum here... It has a wealth of info.
I would suggest just buying a "package" from either Brodak (probably best since the kit is from them anyway, and Dennis is SUPER HELPFUL), or RSM for the first E plane you do.
After that, you will have an idea of what you do like and don't like, and you can piece together your system on your own for the second plane.
You'll never have to worry about fuel proofing your plane, or the covering peeling. And no wipe down after flying.
Flipside is that LiPo's should be WELL RESPECTED and treated like a loaded gun. There is always some slight risk of fire.
My E Oriental-
Oriental ARF with mods to the LG area and cowl, and improved controls.
Battery- 4S Thunder Power 2100- $30 on sale (I will never buy anything else, they are a superior product)
Motor- Exceed RC Rocket 3020 (about 4.5oz) $20
ESC- 50A from Eric Rule at RSM (could have gotten by with a 30A, and been lighter and cheaper, a lot cheaper)$50 ($20 for a generic 30A ESC)
Timer- KR $50 worth every penny, in my opinion
Prop- 10x5 Xoar $6
Vented Spinner from HK $4
Hope that helps,
