Well, since I orderd another 450 clone to use for parts to fix the one I crashed, I pulled the trigger on a Flybarless head to go with it. We'll see how easy it is to lock into a fixed pitch by either shims on the main shaft, or replaceing the bearings in the blade grips with a shim. Either way I will definately have the training gear on this puppy. LOL

Um, just an opinion from the peanut gallery. I dont know what all your running on the 450 clone, but if you have a programable TX, just set up a flat pich curve.

That way down the road when/if you want to go with the CP FBL, you dont have to undo all the lock down ideas or blade shiming.

If you do move on to CP, you will thank me. The handling is soooo much better than a FP.

JMHO because I've been down this road and still fly 2 FP's, but I love the CP's and need to get rid of some bad habits I learned on the FP helis.

what habits? don't CP tilt to the left when take off? It might be wrong place to ask but I want to know also what is difference b/n real and RC CP helicopters?

For one thing, slaming the throttle down and going into negative pitch, learning to use TH and IU for the other.

All helis I've had have some drift when taking off, this isnt a CP thing only. As for the difference between a real and RC heli, I wouldnt have a clue.

Jeesh, its to early for all this thinking, I'm only on my second cup of joe

I am using the Tx/Rx from a Walkera V200D01 and it does not have those adjustments. It is pretty inexpensive and so far fits the bill. I have considered the possibility learning CP, but at this time I am very content with where I am headed with FP. I will look you up to offer thanks when I decide to switch one of these over to CP end fall in love all over again.

When you crash real helis, you get hurt too.
Most things that happen in a rc CP heli are pretty much the same in real helicopters except the smaller you go, the faster they happen.
The real helicopter is limited by blade tip speed. It must never exceed the speed of sound. +1 on Warhorse's response. You also need major adjustment to your use of the throttle and the cyclics. On a CP, if you bang the Ail all the way to the side as you need to in a fixed pitch, you may end up upside down. There is a lot of adjustment to make after flying a 45 degree flybar fixed pitch. That is why I modified my MJX to make it fly more like a CP, to reduce the adjust between flights. Flybarless is also an adjustment, but a good one. You issue a command, and the heli responds without the delay of a flybar.

thanks. I'm glad that I'm not pilot of real heli. Actually, when I hover f45 in my small room I think there's no much difference in the way I do it from how I would fly CP except negative pitch which I don't see use in real life. Do civil helicopters have negative pitch? My question was about mechanics: do real helis have servos like rc, how they are balanced( you can't just remove blades and scale them can you?) I was looking for answers in youtube but found nothing.

I think only enough to allow autorotate. I'm sure they have some kind do electronic assist. A friend of mine built a kit helicopter years ago. His was all mechanical collective controls. The blades he had to hand build out of select wood they supplied in the kit that came as a rectangle 2x10 . And yes, balancing everything was critical. And yes, he did fly it when he took lessons. He later sold it because there was no market for his services and it was not suitable for our winter climate.

Try reading this as it pertains to real helis, seems we know most of this already and shares the same characteristics with RC helis.

Just learned that when you buy a flybarless head kit, most of them are not the complete head assembly as you need to use parts from the original head, like the featering shaft, to complete. On top of the, the head from the clone kits do not use the same feathering shaft. More parts to order, so it's a good thing I love shopping.

Interesting tidbit. I use scotch tape, but we are taking about grams and they are talking about pounds.
