With the Electric Tail Motor, the GY240 Gyro will hold the tail (better than the Rate gyro), but not Rock Solid. No matter where you set the gain the tail tended to wiggle (you could hear the motor oscillate in RPM). Then you also have to worry about the tail ESC shutting down when it reachs its AUTO-CUTOFF voltage, especially if you use the C-12 ESC, that was one of my biggest issues. You be flying fine, then without warning the tail motor would shut off, causing the AXE CP to spin uncontrollably.
Once I switched to the BDT (Belt-Driven Tail), performance became ROCK SOLID, no matter how hard I push the tail, it holds position. Lately I've been doing hard piro's, 360 tail spins, and when I stop the tail it HOLDS! So well in fact, I noticed the tail boom flexing under load, so I added some boom struts to stiffen things up (more modified Align parts).

So for the STOCK AXE CP the gy240,c-12 esc ,and the BDT should bring the axe up to speed with some of the higher end helis? Thats about 250 dollars right? I know its a training Heli but really thats all I need. Will this gyro work with brushless motors later down the line?

Status: offline 		I just put a 240 in my AXE and used the stock 3 in 1. It is an easy install. It holds the tail a lot better. There is just a hint of drag. Sort of an over shot then back to the correct position. The gyro cost is almost the same as the total for the AXE.

The Axe is not a trainer heli, It just happens to come with something that most heli's do not and that would be the training gear. Usually that is seperate cost to purchase with most helis. .30 sized helis don't come with it yet people put the gear on it protect the heli while learning to hover. If you want something to learn orientation on I would suggest a coaxial heli to learn on. Too often I see someone jump right into cp helis get frustrated and sell it because they can't fly it.

If you get the belt tail mod and the GY240 you'll be good to go. If cost is a concern I would learn on the stock unit as hovering doesn't require alot tail movement anyways. Since the gyro plugs into your receiver it doesn't matter what your power source is, Brushed brushless etc. You only need the C-12 if you want to hook up a gyro to the motor driven tail and even that is optional to a certain extent with some gyros. Not all gyros will work properly without the tail esc so choose wisely.

Status: offline 		Anyone have any suggestions for calming the tail wag on an AXE-CPL? I (and one of the local heli experts) have adjusted the 3 in 1 from one end to the other, replaced the tail motor and the tail is still ultra sensitive esp to right yaw input. The tail motor zings up and down rapidly and it is a handful just getting the thing to hover. I have mostly worked the left-right bias pot and the gyro gain pot with some improvement but not much. I almost wish I had a dual-rate switch to soften the tail up some.

Thanks for any help/suggestions!

Status: offline 		Hey guys. I posted to this thread a long time ago. Since then I have moved up to a T-Rex450. I am also flying a T-Rex600N and just recently a T-Rex500.

Anyway, not to rain on anyone's parade, but if you are going to put $200+ in to an AxeCP, would it not make more sense to just go ahead an buy a Blade 400. I have never seen one fly, but from the review I have read, it seems like a great deal for $460.

By the way, I have an AxeCP for sale if anyone wants. W/ 2 LiPos (no charger) and a bunch of other stuff for $90.

Status: offline 		What does it matter if you crash a blade 400 or an Axe Cp with $460 dollars invested in it? You still have 460 bucks worth of junk when you crash. Alot of people complain because they've dumped 100, 200, Even 300 or more into there Axe and then get all bent out of shape and say " I could've had a trex for that kind of money". What they aren't accounting for is your still going to crash while learning and now instead of starting with a 200 dollar heli now they have a 500 dollar heli and putting that same kind of money in parts. Now your approaching a $1000 bucks and could've had a .30 sized heli with radio and support equipment. It's not so important how you spend the money, It's what you get out of it that's important. As the old saying goes, "Hindsight is 20\20.

My MX300 (was an AXE CP), has about an additional $300-450 dollars in ad-ons (not including the DX7), but I have one hell of a heli, to LEARN & CRASH with, rather than CRASH my new T-rex 500, which is twice as big & expensive when it comes to parts!

Status: offline 		Actually Rotor13B has a GREAT point. The initial price of the Heli is not as big a deal as the repair cost.

With that in mind, I have found that T-Rex parts are 1/2 OR LESS then the Axe CP parts. I don't know about the Blade 400.

If you don't believe me, go and do some price comparisons.

I don't really care what anyone flys. I am not a T-Rex fan boy. The point is that you are enjoying the hobby. If you have a $2,000 Axe CP, and you are happy with it, then all the power to you.

Happy Flying!

Pics go a long way thats a good deal.

Status: offline 		Thanks for the comment. The Axe CP is sold. Actually, when I packed it up, there was a lot more stuff then I thought. Anyway, I am happy and hopefully the buyer will be too.

Status: offline 		I have hooked up the gyro and esc and tested. The tail motor kept twitching ,on off on off, any ideas. other times the tail motor would run with no power up to motor just sitting on the ground. dont know I will get more time this afternoon to check it out.
