Hi Vronny. Yea I've been a little busy with traveling and stuff, I didn't want to take the cb10 with me as it is bulky. But every time when I get back to Hong Kong, even the new batteries would be pretty much dead after a charge . So for now I'm just putting it off until I get some cheap batteries on eBay. Do these batteries need some sort of special caring if they are to be left unused for weeks at a time?
How are you enjoying the cb100 Vronny? Besides the slight problems we all have with it once in a while.

Surprisingly, it could see the difference, and it was kinda interesting. Passing results along.
In the results table, the last four rows show values adjusted for a hovering fictious heli that is 50 grams AUW (just a basis for comparison). Even given the spread in repeated trials, it is pretty clear that the 'Q' blades require less actual mechanical power to achieve the same lifting thrust.
More details on the test stand are in my blog.
I definitely love the "Q" blades, they last so much longer since they are more tough. Both blades right now have a half inch crack in them, it is taped up a little, and the cb100 still flies perfectly true! (while the battery lasts...) The Q blades are quite resilient blades, one of the LHS I buy from said to me "ahh... you figured out the secret... darn it"
