I have been putting together a new HBFP, useing the carbon frame and slo-max with the dd tail and M-24 blades and new 4 in 1. all this stuff was new in the box. now the problem, the wiring seems backwards on the 4 in 1, first I noticed the servos were working back ward ? change the setting on the tx and fixed that, then when I put power to the motors they spin backwards ?? so I flip the wires over so the red wire is to the inside and they spin the right way ?????? having all kinds of trouble trying to get this thing trimed out, tail goes crazy and seems to stop responding... has anybody heard of anything like this http://static.rcgroups.com/forums/images/smilies/confused.gif thinking of trying to send back the 4 in 1 for a new one ????

If you are using the 300 sized fiber frame from Heli-Fever one of the servos mount backward compared to how it is mounted in the hbfp frame so that will explain that reversal. When you set up the DD tail the rotor will run backwards because it is not geared. So that is normal. I'm not sure about the slo max but if the rotor head is running clockwise all is well! I think you are in good shape! :thumbup:

Watch the clearance of the flybar to the antirotation device.

to late on the antirotaion device !! :wow2: broke it right off. its ok now, cut one off the stock frame and screwed it on, think it works better....

got the servos working right, and even got the motors working right. but dont understand why the wires are backward coming out of the 4 in 1, the + has to go to the - on the motor to make it turn right...
just was wondering if that would have anything to do with having such a hard time triming this thing..

thanks for you help !!!
