29kv with a 6x6 and a 4s is a great combo....... to pack with you for early season hiking in case you get lost and need to start a fire quickly. Ask me how I know this.
30oz on a 36" wing puts that in 09 territory, maybe even a light norvel or fox 15. So you want something in the 10kv range swinging an 8x6 or 9x5 as you will need the thrust at that weight.
