I'm glad you got it working! My brother is getting a Tx610 and wants to use it with a 1SQ so this is helpful information, thanks. The 1SQ is a good little heli and there are things you can do with it to affect how challenging it is to fly so it can be a good learning tool. A couple of thoughts although you may know this stuff already (in which case my apologies and just skip it):
- If you set the gyro gain low, like maybe 30-40% or lower (see page 11 in the manual and ignore the stuff about heading hold vs. non heading hold since that doesn't apply to the 1SQ) the 1SQ will be fairly docile. This doesn't mean that it won't get going fast if you let it, but it means it won't be quite as squirrely to begin with. (It also means that it won't stop as fast too so don't let it get going in the first place unless you have some room). Please note that since I don't have a Tx610 I'm guessing to some extent. If you find that it's really sensitive at 30-40, try either reversing the gain channel (if possible) or else setting the gain to 60-70% instead.
- As your confidence and skils increase you can turn the gain up. Once you get to 75+% it is pretty sensitive and that, along with high control rates will allow you do try flips. I suggest that at that point you try your first ones over a soft surface and up high, just saying..... again note that I am assuming that with the 1SQ and the Tx610 that gains closer to zero = more docile.
- Speaking of control rates, see page 8 in the manual. The explanation there seems a bit confusing to me but the bottom line is that the switch labeled D/R on your radio can be used to switch between two different levels of control sensitivity. This is different than the gyro gain but has somewhat of a similar effect. On an airplane it would mean that the control surfaces move less when on low rates and more when on high rate. Lower numbers will mean less sensitive controls and higher numbers will mean more sensitive controls. Assuming that this Tx works similar to others, you might try a low rate of around 50- 60% for elevator and aileron and a high rate of 80-90% for starters and leave the rudder at 90-100% for both high and low rates.
- Expo(nential) can also be your friend (again, see page 8 in the manual, there are some good graphs there) because it helps decrease the sensitivity of the controls around neutral. With a heli you are spending a lot of time making very small nudges/bumps around neutral (unless you are flying 3D) and so decreasing the sensitivity there can be helpful. In your case I believe you would want to use a negative expo number. If you use a positive number it will do the opposite and make the controls more sensitive around neutral. Note, just for future reference, that for other radios like Spektrum the sign of the expo is switched (i.e. for a Spektrum radio positive expo tames things down and negative expo makes things more sensitive.) For starters you might try expo of between negative 15 and negative 20.
Note that all of the above are a matter of preference and interact with each other so if it doesn't feel right don't be afraid to play around and try different settings to see what effect they have (perhaps move in small increments) because they can really change the way the aircraft feels and therefore change how successful you feel!
If you can hover the 1SQ I don't think you'll have any problems with the Blade CX. The CP will be considerably more challenging and practice on a simulator would be very helpful if you have one. There are a number of good heli-specific resources available including www.helifreak.com
among others that you might find interesting and/or helpful. There is also a good 1SQ thread here
in case it is helpful.
Good luck. I'm no hotshot pilot but am happy to help if I can so feel free ask questions.
