With the blades spinning freely in one direction is normal, that's the one-way bearing for your auto rotation .Just follow the align manual Ans you will be OK on setting up the servos

So then, don't land on rocks
I've never understood this. It's a really common complaint - landing gears are "too breakable" or the tail dips in the grass, or whatever... You are in control of the thing. Helicopters are supposed to land softly. Get some plywood and make a heli pad, at the very least.

??
lol i know the end result is my fault and i am in control im just trying to get ideas for the best possible setup! im not gonna dog anyone or any heli for my problems jazz its not my style
ive found the best thing to do when in doubt about things like this is ASK the only stupid ? is the one not asked. then read the manual as u already have some expirience to go by and relate better to what the manual is trying to tell u. this is not my first heli dude but i do still consider myself a beginer to intermediate pilot(probly will till i can flip and tic toc.) is there really a "norm" when placeing the esc bec??because if under the belly is where its supposed to be i will go that route but im lookin for the most crash resistant setup i can to minimize damage to the little guy as i know it will most likely happen sooner or later. i mean really guys id bet 100 dollars right now everyone reading this has crashed lol. i know ive had my share and will continue to. oh and as far that plywood helipad i already have a 4 x 8 piece of osb plywood i subfloor glued laminate snap together hardwood flooring too. it looks pretty bad ass with the theli pad already painted on it. now i just need to figure out a way to get a piece of wind ribbon up on the powe line to stay put. then i gotta windsock too lol thinkin about tapein a piece of cardboard to it so it cant wrap up like the last one did. jazzy thanks to all any other tips for us newbs.... if ya wanna see my flight skillz (witch arent much) go to my youtube channel: http://www.youtube.com/user/chiefsnu...t?feature=mhum |

Well, the 250 is kinda small, and I didn't really feel that there was a better place, but I keep a floor mat in my car for flying if I need it. I think some people put it on the side and in the back. Look back through the photos in this thread. There's a ton of ways to lay it all out. You don't really need a BEC if you get an ESC with a good one built in.

The Phoenix 25 is what I use. It would be fine. You don't need a BEC with it, but I use one anyway.

The external BEC provides more reliable power for the receiver and components, and it's slightly more efficient as well. I can also adjust it anywhere between 4.8 and 6 volts to run the 250 - I set it at 5.5. However, it is not redundancy, because you need to disable the built-in BEC in any speed controllers you might use. I mounted the ESC under the motor, which places it near a heat source, and this is risky because one primary cause of built-in BEC failure is heat build-up. BEC failure can cause temporary or permanent shut-down of the receiver, so it's pretty dangerous.
You have choices though. You could mount a Phoenix 25 on the side of frame or underneath, and it would probably be fine without the external BEC.

Hi Jasmine, I posted a question about bec's in the newbie thread but I couldn't get a good answer. I was wondering if you could help me out.
How do I determine exactly the capacity of the BEC that i need? The short answer I got was 5-10A on small helis and 10-20A on bigger helis. I'm trying to figure out the "why" behind this. I know bigger helis have bigger servos that probably run 6 volts all the time, but I just can't get the answer on how to determine the max amp draw (if it's even related to this) all four servos will use to figure out what capacity a BEC needs to support them. |

2 or 3 amps is more than needed.

For the servos, you'll want the worst case scenerio...stall current.

Yes, I know this. Although helpful, it does not provide the answer to my question.

Q. How much amperage does a digital servo draw? A. It depends on the servo and the load. For standard sized digital servos, a good rule of thumb is 2A at max torque. Ok that's sensible. 2amps - for standard sized servos -- which covers what exactly? What about for premium servos or even HV servos? How about for receivers and gyros? I didn't even know rx's draw current also now that you've mentioned it. The amp draw info is simply lacking. |

I ran out of the shims that goes between the head and grips, do they sell them separately or I have to piece them out

i am haveing some trouble settin up my trex 250....
i have a align 15a esc and castle compatible bec.. the wires from the esc are done right as this heli was purchased used with the red wire already took out of the equasion in the esc. and i have a ar6100e rx the ports on it are as follows from left to right.... batt thro ale elev rudd gear aux1 i am told i have to connect the pit servo to aux 1 i am unsure where esc and bec wires go?? ale elev rudd and gear are as follows i think ale is the front servo on the left side of the heli lookin at it from the tail in position elev is the rear servo pit is the right front servo rudd is the 3 wires from gyro gear is one wire from servo.....although i dunno if it goes in the + or - positon (top or bottom)??? i also dunno witch way to plug the wires in?? i assume black is plus and white is minus am i correct?? also need help on bind process... do i need to have all the servos pluged in exept throttle or what?? i do have bind plug and have been told it goes on the batt slot am i correct and can anyone put up an easy process for all this it would be a vital post here in this thread..... thanks alot guys |
