well after turning down a lot of pi settings I managed to get a normal flying Tri. My problem now is I think my servo is done. I just discovered I purchased a regular servo and not a metal gear (my fault). Fair warning to anyone on the fence about MG servos or regular servos. In the end I have a tricopter that spins in circles like a tornado. Hobbyking here I come.

forget hobbyking grab a hitec hs82mg from servocity and be done with it. i have a nice pile of hobbyking tail servos that are broken. still using 8 year old hs81's out of old combat wings with no problem. i know it hurts to spend $20 on a servo but its good money spent.

I am having a problem with the motors. I am using 30amp simonk flashed escs with 1300kv motors running 4s 2650 zippy batteries rated for 40c. My flight controller is a kk2.0 from hobby king with an lcd. The problem is with throttle, its fine about half way up the throttle but then it seems to jump up in speed really fast when I reach a certain point. The noise doubles, the vibrations double and really wants to take off and fly and away. When I try to bring down the throttle, it doesn't seem to have much effect until I cut the throttle entirely. Any ideas? I have already turned down the stick scaling from default of 90 to 35 trying to get rid of it without much effect.

This tri is going to climb like a rocket. I'd put a 3S pack on it to tame it down a little. I expect your props can't handle the rpm.

i have had this happen before. you need to use gyro pads on the control board and ballance your props. if you have already done this try replacing one prop at a time. i know this feels hardware related but in my case this fixed it.

i just paint it. i used a (good) brush on neon yellow from michaels craft store and a foam brush.

Hey hallstudio, I am looking for a gimbal setup for my gopro and saw you built a version of the one on RCGroups I was interested in building. Would you be at liberty to release how you built yours? You have the design nicely covered in black. The original design called for fuel tubing though it would be my understanding that fixed and solid parts for making the connection to the servos would be better but I could be wrong.

One "clone" of matthall's simple-T:

Some in-flight pics (taken by my friend) https://picasaweb.google.com/joouni/...v4vumI5a-U9wE#

Flies great, I've flown it 5 batteries.

I've made many changes to the body but it's really rigid. Many crashes to hard snow and no problems. Flips are just great, roll-flips can be done almost at keeping the same altitude.

I truly recommend tricopters to quad flyers. I'm not sure yet but feels like I'm not going to fly quads anymore..

Today I mounted GoPro 2 with the casing on it (3S, 1400kv) and it carries it well. No gimbal / stabilization.

I'm amazed how stable it is :O Maybe the wooden body is the key? Dunno. Here's a cruising video:

Tricopter Cruising (1 min 31 sec)

Also posted this elsewhere because I took video from yaw mechanism (starts at 0:57):

Tricopter (wooden) onboard inflight + yaw action HD (2 min 8 sec)

To those folks using the sunnysky motors, I've just received mine, it's my first time using these. I noticed that without removing the motor shaft, the motor cannot be mounted on the wooden arm for the t-copter as the shaft will be hitting the wooden arm.

I figure that I would need to remove the shaft, and saw that there's a circlip. Before I remove the circlip, I wanted to check first with you guys that removing the circlip is all that's needed to remove the shaft, or do I need to do anything else like reverse the shaft mount or something else?

Instructions would be very welcome on how to do this as this is the first time I'm doing it and wouldn't want to ruin the motor.

Thanks in advance!

Wouldn't it just be easier to drill out the arms?

Assuming they're wide enough so the hole won't sacrifice strength, and tall enough that the shaft won't protrude out the bottom of the arm.

If the top shaft has enough room for your prop and fixture, just poke the bottom shaft through a plastic bag and cut it clear. I used a steel saw.

Thats what I do, except I use a Dremel

^^^^^^^
Me too. I use parcel tape to completely cover the motor.

So you guys are saying that I should simply cut off the shaft? Ok.

Just thought removing the circlip would do the trick. Sorry, I'm not that familiar with these motors so thought I'd ask you guys who have the same motors

I would cut it off just so it's flush with the mount surface and I'd make very sure that nothing from the cuttings can get into the bearing or the motor.
The dremel with a cut off wheel is perfect for this task.
