Rc Helicopter
I have a Caliber 30 that I’ve been working on for about 5years now. You know mess with it abit and put it up. When the heli is at idle should the blades be rotating? I had to squeeze the clutch because it expanded when the lining fell out so not sure if I have enough clearence. Engine starts fine and I can hold the blades but when I let go they want to rotate.I’ve seen them do it and I’ve seen them don’t, what can I saw? If you need to to sort of an effort to hold the blades still then its probably best if you loosen the clutch a bit since it’ll be very unpleasant trying to carry the heli while at idle to the helipad when its trying to spin, but if your fine with that it shouldn’t be a problem. I have looked at videos and have seen it both ways. I think I would like to have them not spinning, it would be alot easier to carry the heli with out the blades spinning. it actually rotates too much where if you let it go and try to stop them it is just too much force behind them to stop them easy. I have adjusted the clutch and now I’m going out side to try it.
I am building a Gaui 550 and am at the electronics stage: when i put in the servo for the rudder where exactly does the servo wire go? … i am looking at pictures of build and it seems that is goes in the frame of the heli - if so then does it go between the belt? …if so then isn’t this a little risky? …but if i run it outside the frame then does it not run the risk of getting caught in the arm that operates the tail apparatus? Also i am thinking of running two 11.1v batteries - i was told if i solder a (single) Deans plug to the ESC then have the Deans series adapter that pugs into it that i will decease current flow thus decreasing my flight time …if this is so then does it decrease my flight time that significantly? vs soldering the series wires directly to the ESC? …. my thought was if i did not, then i could always have the luxury of coming back if i decided to get one battery (vs the two in series) and plug it in straight to the ESC Deans.
I ran the wire inside making sure to use zip ties to keep it against the frame. As to the batteries, just use the battery series connector, you’re not going to notice the difference. People that say you will are kidding themselves. There might be 10 seconds worth of flying time difference.I do highly suggest you use a separate 7.4v battery and ubec to power the electronics though. I don’t like the built in bec in an esc dropping the voltage from 22.2v down to 6v. A nice little 2S 1500-2000mah lipo is light enough that it doesn’t change much of the flying characteristics. I also like the fact that even if something goes wrong with the main power system you still have power to the receiver and servos to try an auto.I have aquired a used Gaui 550 with a bad OWB. What is the lastest and correct part numbers for the bearing and shaft? Better 19T or 20T on the bearing? Any help appreciated. Live long and prosper! Sorry, been away on business for a week. You can find most of the parts for the Gaui 550 at www.readyheli.com. Also, the pinion you choose will really be determined by the motor you’re using and the head speed you want. A higher pinion will give you more headspeed but be sure it’s not too high a gearing which will bog down some cheaper motors.
Thanks Druss, have you ever had an intermittant OWB? I took this thing out and it seemed to be fine, reinstalled and started up slow, then it would let go and come back with some very heavy tail swings!!! Scary! Anyway, I have used Readyheli in the past but they were out of stock on the shaft so I found OhYesRC. We will see how their service is…. The motor is a Trex 600 and I am experimenting with different gearing, I bought this heli off the forum, it has been set up for some heavy 3D which is NOT my thing. Right now I just want to get it in the air. I’ve never had an issue with the one way bearing, if you’re having any troubles with it I’d suggest replacing it. readyheli does seem to be out of a lot of the parts. there is an online store up here in canada called www.rotortech.ca that carries gaui parts and a store in hong kong called www.flying-hobby.com which I’ve ordered from.
