Default Nexus 30 Tail rotor

Ok....I'm plagued with a nifty tail rotor issue..I've made sure that all of my mechanical connections are tight and functioning as advertised.

I added about 6 degrees of pitch to my tail rotor blades, and made sure my Gyro is reacting correctly(i.e yawing the helo by hand to get a reaction from the Gryo)....(I've also tried the gyro in reverse mode...no joy!)

I get it up to just to where it's light on the skids, and it starts to slowly spin clockwise, then starts a wild clockwise spin...if I power it down BEFORE the crazy spin it corrects and stays straight, but if I add a little throttle off she goes...

The Gyro is a Heli-Max w/gain and center pot controls...

thoughts, questions...


Oh and where in the H3LL does one find large training gear for these .30 monsters...I'm going through wood dowels like candy

You can try these guys for a bigger training pod. If you go to their site look under training and it will show you a few for a bigger size heli. The pod is the way to go because it holds the heli about 2 feet off the ground. Talk to them and see what they say

Classic symptoms of a reversed gyro. Check again.

It might be reversed at the transmitter. But it's definately acting like it reversed. I once hooked up my Raptor 90 wrong and it did exactly the same thing. Spooled up fine and then went into a wild spin.

I'l take a look if I can find time today....The reversing I did was at the transmitter...The Gyro doesn't have a reverse option on it

Are you sure? Most gyro's have a gyro sense switch somewhere (pot)

It doesn't look like it's got one to me. And you shouldn't really be using a micro type on a 30 size bird. That's for the little electric types really. Check everything again. Are you SURE you have the belt on right. Is the servo arm on correct. Are the blades on the right way. It's going to be something simple !

Mind you, Mines overkill. Got a setting for everything

Belt...it aint got no stinking belts.....

I just finished reading [link=http://www.runryder.com/helicopter/t228476p1/]this[/link] (Sorry for the non-RCU link) and if memory serves me correctly I am using thesame radio the Op is...

I purchased this thing as-is, and have not added anything except a new set of skids


I'm at a try/buy/replace it as needed stage

If you were me and had to choose a complete new radio package AND you were on a budget what would you buy?? Not looking for 3-D performance out of this first Helo!

Remember to do this check with the idea you are flying the NOSE not the tail.

Give right rudder, the tail blades should change in pitch so as to push the tail to the LEFT. If thats wrong reverse the rudder channel.

Once you get that straight, pick up the helicopter by the head and turn the helicopter to the left (counter clockwise looking from above) and watch the tail blades, they should perform the same way as in step 1 by giving right rudder to push the tail left (read this a few times till it makes sense). If the gyro is reacting opposite flip it over and remount it.

Mmmm. It's easy to forget the easy option when you have an expensive gyro I guess

I'd still recommend a heading hold gyro like the GY401 though.

Absolutely!

I've just been around the hobby long enough that we used to have to do it the hard way.
