RE: throttle adjustment issues sudden altitude drop
Shani,
There are many reasons, low battery change in air temp in your house to site a couple that we all run in to. I never use the throttle hold as I found the Heli is just not that stable in that regard due to many factors. OH YES you can use throttle trim hold but only for a couple of minutes if that unless you do a whole lotta work! When you first start up on a freshly charged battery there is high surface charge you need to burn off before the battery becomes stable to do what your explaining. For me, I can be hovering and in one moment the Heli lifts and goes for the ceiling! so I am always on the ready. I have noticed too that when the house is warm of course the air is thinner closer to the ceiling which accounts for some of that problem.
Fly bar, well this Heli is a great little flyer. She'll fly with broken, bent, parts and with some hanging off too! The fly bar can be used over and over as you explained just by using your eye site to get it as close as possible. HOWEVER, what will suffer greatly flying this way is a total ability to hold a hover and hang the Heli like from a string. I would not suggest you keep replacing the flybar unless it becomes damaged in the rotor post where it sits where it little posts or ears make contact. Wait until your a much better flyer then when have all the stick moves down and want to do some real tight hovering and landing on the TV tray and smaller objects in the house you'll have to take that little bugger and tighten her up proper. That means, blades, inner and out shafts, flybar, and all must be perfect.
A word of advise. If you like the hobby and intend to go deep into it in a few months, then get yourself a Simulator (sim) and then a larger Heli, don't buy all of the aluminum bling for this CX. First, it weight's down the Heli and eats up your batteries sooner! Two, there are other things you can do that will make it fly better and will give you a better pay off for your further investments into it rather than aluminum! Thats my two cents worth.
Good Luck and welcome aboard Shani
