do i have to rebind if i change a servo? i put another servo on, and plug in battery and heli started acting like the tx wasn't on, but it was. also how do you bind a blade400?

To rebind you need to put the bind plug in the Batt pin in the receiver. I think on the DX6i there is a switch or something to go into bind mode. After the bind plug is in, plug the battery in. Then do turn the transmitter on and do the binding process. When you say it is acting like the helicopter is on, are the rotors spinning or are the servos moving. As a side note did you get the servo horn 90 degrees to the servo and is your swashplate still level?

yes the main roto starting spinning but luckily my hand was still on the battery plug and i unplugged it real quick. but i was plugging it up to let the servos set their self before i put the servo horn on, but the orginal horn won't fit on the new servo, and i can't get the swashplate link screw to start in the servo horn that came with the servo [:@]

i got the screw in finally, i found a nail that was would fit perfect in the old servo horn screw hole, and heated and made the hole a lil bigger. the battery is charging, but i'm trying to decide if i will see what happens without binding first. surely i wouldn't have to bind for replacing a servo?

got it all back together, but the servo horn on 90 degress but swash plates was unlevel, so i took the sub trim and trimmed it till level. is that the correct thing to do?

The only thing you use subtrim is for is to center the servo horn to get it to 90 degrees. Then you level the swashplate with the links. The rotor turning when plugging the battery in is a major safety issue. If you have the instructions to reprogram the ESC I would recommend doing that so it can tell were the low throttle is. And rebind it and make sure the throttle is all the way down.

scooby, if its the blade 400 with dx6i you are talking about, mine was doing the same thing.

Firstly to rebind, you switch in the TX with the trainer/timer switch held forward and the the receiver already on with the bind plug inserted. NOTE... If you 'accidentally' switch the tx on while the trainer switch is unfortunately being pushed forward by the bag it is sitting on, it will wipe out the bind with your receiver....

Now as for the spinning blades - if you power up the TX/RX when you have the throttle hold on, it will cause this problem. Simply shut down everything and start again with the throttle hold off.

Should fix your problem, it did mine. Oh, and no, you shouldnt have to rebind with a new servo, but once all your trims are reset its not a bad idea to rebind so the failsafes are correct.

i haven't did a rebind yet, so far i've had no probs with it acting weird. i'm thinking that maybe i didn't have the tx on or something. but when i get time i'll try to rebind it. i unplug the wire that goes from the esc to the rx, and put the bind their right? i just got done changing the connectors on the blade400 and the battery that came with it, so now i'll have 3 batteries to use with it. since my belt cp is down and out till i can afford better servos, its cut down on my flight time waiting for the one battery to charge after 7 mins of flight time [:'(] LOL i got very lucky this morning when i got my blade out, i put the throttle hold on to check something and while i was moving the throttle up, i noticed the swash plate was angled forward and to the right, so the servo had quit on me, but after a few mins it started working and acted fine. but still not sure of that servo i had a eflight servo on the tail of my belt cp( the tail servo wasn't even working out of the box on it, so my local hobbystore gave me that one to use since it matched up pretty good) that i took off and but on my blade400. i'm just glad i noticed it before trying to take off and sent the main roto blade straight into the ground [:-] so now that i love flying my blade more than my belt cp, i'll want better servos for it first and my belt will be grounded for a long time [&o]

but for adjusting the servo with subtrim, will it be okay to keep it this way for a week or two? i don't have a pitch gauge, and i don't really wanna start adjusting the links and mess the pitch up on the blades, till i get a gauge

The bind plug connects to the battery pins - when looking at the stock setup from the boom side its the vacant pins on the far left. The ESC provides power through the throttle connection. If you use an external BEC like I do, you have to wedge a wire into the unused top pin and short it to earth.

Yeah, adjusting with trim or subtrim will be fine for the short term, providing you are not flying full on 3d that is, as it may stuff up the full travel points.

i dunno if a blade400 has BEC or not? its all stock

i'm not doing 3d i just today starting forward flight, but the tail pointing toward me the whole time hehe
also for ugrade servos, i'm interested in the Hitec HS-65HB Micro Servo, but i'm confused, in the pics at ka-planes.com it shows three holes for mounting, with middle holes which i'm sure is need since the stock holes are in the middle. but at other websites like horizon hobby, the same servo pics show only 2 holes and not one in the middle? is their a way to add a middle hole if it don't have one? or whats are some better servos that will fit blade400 and around 25- 30 dollars

On the B400 the BEC is built into the speed controller. Do you get 7 minutes of flight on the B400 or Belt CP, because I get 9.5 on my Belt CP with all aluminum parts.

Nick

well i've got the timer set for 7 mins on my blade400 and stop after that, and the voltage on the battery is around 11 volts, i have done 7 and half and the voltage was 10.8 on my beltcp was timing myself for 10 mins or so and then i would quit. what flight time are others getting with blade400?

so with stock blade400 i plug the bind into the empty slot on tx on the left side. when i plug in the battery with the tx off it won't start trying to spin up with the esc still plugged into rx?


i wish i still had my beltcp running, but i ain't having any luck with servos in belt or blade had servo go out on belt cp and so i bought 2 more esky servos, and installed one and was like okay i got a backup, but like 3 days later i was hovering and noticed it got really hard to control and landed, and came inside and both left and right servos had stopped working [] i'm prob lucky i didn't crash. i couldn't afford better servos because i spent alot of money on 2 ESC on the belt because the stock went bad, and the first one i bought, i couldn't get to work so that was 50 dollars lost, so then i order a dynm esc, so that was another 20. if it wasn't for that and the servos just quitting on me, i would be doing pretty good lol. its weird though, i hadn't stripped any servos, they all have just stopped working completly[:@]

when i do a bind, the light on the rx stops blinking, but the gyro light never stops blinking. is this normal?
