Right so it looks like one of the silent upgrades walkera are known for - so how well does the tail hold with this new Rx - the big criticism with the older rate gyro's on the 4#3 series was that the trim drifted as the battery run down - does this new gyro hold the trim all the way through the battery - and being a "simple" HH does trim adversely affect it ?

In my case, Jason's tail rotors were a money saver, at one point, I was breaking 3 stock tail rotors a week. After I got Jason's rotor, I have not broken anything in the tail section since. (I use a pair of trimmed 4G6 tail blades with Jason's rotor) If Jason can get it right, it is a treasure to be had.

Well, I don't think the trim is drifting, but when hovering you can have the gyro giving small right pushes. I am not sure if this is a trim issue or something else, I haven't figured that out yet. It doesn't always do that...

Find the vibe,,main shaft is bent or wires are touching the gyro case or pos the tail boom is loose or split at the main body mount? balance the blades also , you can do that with just a bolt and two glases.

Check your tail boom as well, check to see if it is tight. Everything I get the slight drifting thing, it is because my tail boom is loose, and affecting the gyro and tail motor. I've gone through 7+ booms, I speak from experience.

The tail is tight. I had some vibration with the blades off, the blade holders were bent a bit. After straightening them out the vibration reduced somewhat, but the gyro still does that thing.

Should it be super smooth or could it have a bit of vibration??

Main Rotor Blade Performance Comparison 4#3, 4#3B, 4#3Q

Built a crude rotorblade test stand last year to tweak a set of 15" blades for a 'FrankenKopter'. Thought it might be interesting to see if it would measure any differences among the (much smaller) 4#3 class blades.

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.

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.

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"

What do you mean by cogging Vronny?
