Thanks for the helpful response Doubletap. I ordered an extra Zippy compact 2200mah.
I noticed there are seemingly endless posts about modifying the Bixler/SS. Many "must do's". Would you guys say there are any areas that need improvement before flying this RTR - besides the usual functional and assembly checks? It doesn't sound like it from this thread, but some of you have lots of experience with similar foamies and may consider some tweaks common knowledge.
