600 Jr Propo Nitro

[Daniel Migneault]

Hello all, I'm trying to connect all servos and the governor on my HR 9020 receiver with no success and i would need help to set my Spectrum dx-9 black edition, at least basic setup, is anyone can help?
Thanks!

 

[Tony]

I do hope you mean the AR9020, is that correct?

And can you post a link to the helicopter you have? That would help out a lot. also, let us know if you are flybar head, or flybarless, and what gyro you are running.

 

[Daniel Migneault]

Indeed it's AR LOL...
and the gyro is a G7703D

 

[Tony]

First thing is first, you should really replace that gyro. I can't find any information on it, but I'm 99% sure that is a piezoelectric gyro and those things have horrible drift issues if you don't let them acclimate to the outside temp. It will work, but getting a MEMS gyro will be much better in the long run. Finding something like the Align GP780 would be perfect and is what I run on my only flybar helicopter. With that said though, if you wnat to use this one, just know that tail is going to be all over the place and not that stable.

As for setup of the helicopter, I can't really see where the elevator servo is on that one. Since it is flybar, it will be direct connection to the receiver so that should simplify things a bit. The head setup is going to be exactly the same as my video on a 450 flybar head, I will post the updated video for you below.


And here is the older flybar head setup video with a DX8. Pretty much the same setup as a DX9


And here is the basic helicopter setup for the DX9

And those are just to get you started. I find that most people learn better by seeing then reading. If you have any questions, be sure to post up with the specifics and let me me know. But those 3 videos (the first one is just an updated one with fixed links, the second one is one of my most popular and has adjustable links) should help out quite a bit.

If those can help?

Is there any way to get clearer images while holding the phone sideways so it fills up my screen? Those portrait style pictures are so small on my screens that it is hard to make anything out. If you can find a google link or something to a manual for that exact helicopter, that would be awesome.

For the gyro, i will take a look as soon as possible!

 

[Daniel Migneault]

Shoulb be a bit better.

 

[Tony]

Definitely better. Elevator in the front... noted.

I don't really know the exact model of that heli, wished you could help, it's an old one...

 

[Tony]

what size engine does this helicopter have? It should be casted into the side of the block.

 

[Daniel Migneault]

OS .50

 

[Daniel Migneault]

It's a 600 class

Okay cool. They made two helicopters that look exactly the same frame wise, and I just had to make sure. I'm about 95% sure you have the JR Propo Venture .50. below is the manual on the helicopter. If you could, look through it and verify everything with your helicopter. One thing I don't like is the amount of plastic that is on this helicopter. This heli is quite old and I would pay special attention to the plastic parts to make sure they are not showing any signs of wear. If they are, they need to be replaced, which on a helicopter this old is probably easier said than done.

Below is the manual.

I believe your right Tony, the other one is the JR Venture CP and it has a single tail Boom brace and a squarish style muffler.

Really appreciate, those infos will help me a lot, i will for sure pay attention to everything and many thanks to all, now if i can find some free time, i will start to investigate and see what's needed.

 

[Daniel Migneault]

One more thing, because i have a Spectrum RX, i remember seeing that some connections are a little different ??

 

[Tony]

I'm not sure what you mean. Just make sure to get the polarity of the plugs correct, and you may have to reverse some servos, but other than that, it's pretty straight forward.

 

[Daniel Migneault]

I will give it a try pretty soon and come back for comments!
