    I already trashed the blades, next time I will glue and tape the blades that is such a great idea and plus it will save money

    go back to page 10 Post#125 for his site. Also follow the thread

    Status: offline     		Gord, My trim is set dead center. I've got two packages at the post office I'm going to get later that I hope are my parts. (gotta plug in the truck today about 27 below) If it is the parts I'll replace everything, trim, and see how things go from there otherwise I'll try turning the screw then using the trim as you mentioned.

    Used to work for a bushpilot in Chapleau Ont. Wanted me to stay through the winter till I found out, not far away is White River, which holds the record for the coldest place in Ontario at --60 F No thanks This was around 1955.

    Status: offline     		Gord,
    Got all my parts today! New upper rotor head, main shaft, new flybar with lightweight ends installed. Trimmed it out at the house in a pretty small space but I'm getting the same "slowing top or gyro" like action just above or at ground effect where the whole machine moves around. Now I know the main shaft wasn't bent after all because it's doing the same thing. Tomorrow I'm going to the gym to see how the forward flight reacts to the new parts. Skip

    Status: offline     		Ok I have a semi big problem with my XRB... Ill be flying and I notice that the heli wants to drift one way-no problem probably just rotor wash off some furniture, until i try to get some left rudder in, but no response what so ever even with my rudder stick all the way to the left, it evens slowly starts to turn to the right!! Sometimes it drifts towards furniture and i need to turn left or correct my patch so i dont hit anything, so far i have been lucky and have managed to not hit the couch or table by just slowly cutting down the throttle and landing softly (kind of ) Once the heli is on the ground and the throttle is off i start the blades up again and voila it turns to the left again. I am thoroughly confused to say the least. I think this tends to happen when i have about 5 minutes of the battery left. Any ideas? Anyone have this happen to them before? Ive tuned the heli pretty decently and it stays in or about in the same spot for 8-10 seconds.

    I find, unless I get above at least a foot off, it will go off in any direction. If the tail swings around, try tweaking the upper blade screws instead of the rudder trim on the trans. If it drifts fwd., back, or sideways, try the screws under the plastic cover on the side. Good luck.
    Wildjones:

    When the batt. gets low the nose will tend to go to the right. In order to turn, one blade speeds up and the other slows down. If there's not enough batt. left, the one blade, the bottom blade, can,t keep up, so the nose will rotate to the right. With a fresh batt., tweak the screws on the upper blades as on page 21 so the trimmer on the trans is in the middle and it will hover without yawing. Then use the trim on the trans. for fine tuning.What it's doing is lowering or raising the blade pitch to raise or lower the torque. Less pitch, higher RPM, = less torque. Hope this helps.

    Status: offline     		No, the rudder is fine, just certain points in flight i totally lose the ability to turn to the left and start to spin out of control....It happened again tonight. Maybe the motors just get hot? I do take breaks in between but am thinking that just may be the problem...I let my dad try out my heli (heh bad idea) and the rudder just stopped....well im glad to know that the xrb takes a drop from about 6ft up quite nicely =P lol

    Status: offline     		Michael:
    When your father was flying it, did both blades stop or just the one set. If only one set stopped it should head for the ground still stable but rotating in one direction. Are you sure the problems are not in the trans. Might check the batts. after the episode before with the batt cooking. Red light on the left should stay on solid red. Have you tried adjusting the blades as they show on page 21 ?. How long will it run before it starts acting up ? Should run for around 8 mins. with no glitches.

    Status: offline     		Not sure about the blades, it fell from six feet pretty quick (as it fell i didnt look at the blades because i was worrying if it would hit anything on the path down.) pretty fast hehe. It fell stable though as it has all the times so far. Im sure its not the trans because the battery light glows bright green and the power light is solid red. Ive adjusted the blades according to page 21 as well as balanced them and did the tracking (bottom blades dont track EXACTLY but are pretty close and the top tracks perfectly). Today when my batt. is done charging ill time how much flight time i get before i start getting the rudder glitch.

    Status: offline     		Ok heres the update. Just flew my XRB and i noticed i onlt get about 10 minutes of fly time... about 8 minutes in the rudder starts to act up. it turns to the left noticeably slower than it does to the right. I kept on flytime just to see if it it would happen. Sure enough i lost left rudder entirely. I looked at my trans and both lights are glowing on steadily and are bright. it seems that this happens about 3 notches of throttle left (roughly from the little lines to the right of the stick). I took a break 5 minutes into the flight and started after a 5 minute break. Three minutes later after the battery was dead i felt the motors and they were warm but just barely. I think this was all that i noticed...
