I am in the process of building a Cambrian ME109 electric funfighter, I purchased this kit with the recommended motor and esc , a Overlander Thumper 1050kv with overlander XP2 40A Esc.

My question is what prop should I use with 3s lipo and also what should I use if I go for the 4s route? On the Cambrian website it recommends apce 9x6 with 3s lipo, is this what I should be purchasing and would this be suitable with the 4s lipo?

Thank You

The 9" prop will be for the 4cell setup. For 3cells, you will need an 11" prop, as per the recommendations on the Cambrian website.

Actually, Cambrian list two different motors for the 109, but only show one size of prop (the 9 x 6). It would seem to me that they are suggesting using the 1050kV motor for 4S use and the 1500kV motor for 3S use, but keeping a 9 x 6 prop in either case.


You could always ask their advice?

Thanks for the reply's, Alan I have emailed Cambrian models and they replied saying that they used 3s with a 9x6 prop and that they know of others using 4s but did not know what size prop they used, so am still confused?
