Nine Eagles Solo Pro 180 3D flight results.

I posted a while back that I just got the Solo Pro 1803D and I have put several flights on it and so far I have to say It flies pretty dam good! Inverted flips,Rolls Tail slides Funnels it does it all pretty well. You can give it full collective and it climbs like crazy and the tail holds perfect. If I were to compair it to something it feels like a Align 450 sport but FLBS. you don't need to be gentile with it you can stick bang it and it just does what you want it to. I was outside today in high winds and I got moved up and down but it managed fine. I was not afraid to push it because it was solid. Now I have been asked how it was going to do in a crash? I can't tell you it has not let me get in any trouble yet. So far So good!! And the radio is not to bad after you learn it.

That's great news. My big concern is how durable it is and the repair parts availability and cost. I also wish I could use my transmitter, but you can;t have it all.

The one interesting thing is the reciever/gyro might be able to be fitted to a 450 with little work it would make a FBL 450 cheap but you have use that radio.

I just got a 180 pro and when I get into fast forward flight it jumps up and down a lot with no wind. Im new to flybarless so I was wondering how to adjust this out. Also it maybe another flybarless question is how do you trim for stable hover my keeps going to the right and I gave it 100% left sub trim but still wants to go to the right. Dose leveling the swash take care of this? It is fun to fly mine has lots of neg for inveted climbs it loops in normal mode with no problem. Range tested the radio you can fly out as far as you want before this little thing disappears.

I got this thing to fly without jumping up and down. The gyro plate has a wieght on it and is not supported on the bottom. I made a small piece of carbon rod and glued it between the gyro ballast wieght and the battery tray to keep the gyro plate from moving up and doun. It can still blade stall in a dive and nose up a little but it flys much better. Also the motor wires were routed next to the gyro rubbing on the gyro I move the wires to the side of the frame and I installed differnt gyro mount tape.
I was flying it hard doing stationary flips and roles buzzing aound I lost it in the sun a little and came full speed into a bush. I hit the throttle hold to late and striped one gear off the main and one link fell off I can not find I was suprized that was the only thing wrong.

I've just bought one too... done a few flights but not tried any 3D yet. How do you fine tune it? For example, how do you adjust the 3G elevator and aileron gains? Also, I find mine bogs when doing full pitch climbs and the tail moves a little on pumps.

Did a bit of 3D today, quite nice, although a little bouncy (bounces up/down, hard to maintain constant altitude), but this bouncy attitude seems to get better as it wears in (first flights were very bouncy, now it's a little bouncy).

Still wondering what kind of fine tuning is possible (3G gain in particular).

Try putting a suport under the ballist wieght that helped mine alot.

extra weight?

Why would you do that? its like putting lipstick on a pig. it needs adjustment. it is going to take time to learn the radio. Try setting the gain with the G.S. switch up to 30 the default is 25. There is D\R take some travel out of the servos so it won't bog it. but like all mini helis collective management is a must. you can't stick bang it!!Oh if you can figure out how to set the endpoint on the rudder to 120 it will make it very responsive.

I think ChopperMcFly suggested extra stiffness and not extra weight... read his previous post. I think I'll try to do what you say ChopperMcFly.

The GS gain from what I gather is for the tail gyro and not the elevator/aileron gyros, but I'm not certain about this, maybe the same gain is used for all three? (but this would make finding optimum gain near impossible in my opinion).

D/R is for ailerin/elavator and tail (and not for collective or throttle), so D/R isn't the path to follow, but rather pitch curve (which I've already played with).

It's simple to set 120 for endpoints on all three (tail/elevator/ailreon) commands, simply go into the menu and do it, but I don't feel this is necessary for now (the tail is already pretty responsive).

Well, crashed mine today (hit the hedge...). Stipped the main gear and bent the tail rotor shaft. Ordered the parts and should have them tomorrow.

But this brings some questions : Is there a full assembly manual. For example, I can't get the tail rear gearbox off (is it glued to the boom or what?).

Also, you definitely need some special tools to work on it, it's so small (and the provided screw driver isn't magnetic which makes it really hard to put the screws back). I've ordered the hardware bag because I can't imagine not loosing any screws, they are so small. Working on such small parts is pretty hard (I'm used to 700 helies...).

Hi... got the parts and more or less finished fixing.

One issue : it seems the conical tail gear is glued onto the tail drive rod (on the picture it looks like there's a notch, but in reality it doesn't seem to be there).

I've tried using red thread lock to weld the gear (plastic) onto the rod (carbon???). Then I tried cyano, but neither seem to work.... what do you think should be used ?

The tail drive rod is carbon it seems... I've sanded it a little hoping the cyano holds better and it does, it's back flying now like new!

However, this little experience tells me that it's worth having some tail rods and gears in stock, because I have the impression it's a one shot build (I don't think you can reasonably take the tail rod assembly appart without damaging it, basically I think you have to dremel the rod to take it out of the tail boom).

The main gear is very easy to change and takes a few minutes at most (just one screw and the main axl pops up then replace the gear and that's it).

Anyone know of a detailed manual for it (an assembly + initial setup manual) ?

I wouldn't mind a forum for the 180 3G, I think it deserves it, it's a real full blown model RC helicopter for experiences pilots/modelers (in my opinion), nothing to do with the toy the RTF box makes it look like.

A few more flights and the vertical tail fin snapped off on takeoff.

The problem is that the skids don't lift the tail high enough and that the vertical tail fin scrapes the floor on takeoff and landing, so it finally fatigues and breaks.

I've added some rubber skid stoppers on the back of the skids to lift the back up, so now the fin is clear from the ground and should be OK.

I've cyano'ed the fin back on and it seems OK...

How are you guys getting on with your 180 3G ?

I am still trying to get stable hover I think the only way is that every time you plug it in you have to trim it because the gyro resets itself. So sub trims dont work. So every time I plug it in I have to give 15 forward and 10 to the left then its a pretty stable hover. I came out of forward flight and it droped a little on the ground and slightly bent feathering shaft now tracking is off on one side. But still flys fine. HK have 750 mah nanotech batterys. 35c that fit this thing.
I notice the tail fin is to big and most of the wieght is on it. rubber on the rear skids is a good idea.
when I put a new gear on my tail drive shaft i did not use ca there is a flat spot in the shaft the gear fits into I had to use magnification to see it. Where do you get parts in one day I have been getting from heli pal.

I would not use sub at all. Adjust the arms to get the swash level and you might be able to straiten out the shaft on a good hard surface and a small brass hammer. As for one day parts you are going to need to move to China!

One day parts for both Align and Nine Eagle at http://www.fxmodelrc.com, works fine for France. I've done about 30 orders there, from small parts to full 700E kit and in all cases I receive it next morning around 08h30 ! It's great to know you don't have to wait for parts, that's part of the reason I fly Align now (I used to fly Century, but fxmodelrc don't sell that, and it took weeks/months to get the parts from heliworld to France).

My trims seem to just work as expected (with memory from one flight to another), and now it's adjusted I've not touched it for some time now.

You say you don't use CA glue because there's a flat spot, I'll check that, but you must put something to hold the gear on the rod otherwise it just falls of doesn't it ?

I'm getting pretty used to the 180 3G now, here's a small video in the garage last week after reparing, see the end, you'll see the tail rotor stops when it strikes the ground, then winds up again (it's when the CA glue broke... I had to reglue it after that, the flat spot has worn off I suppose...)

Watch at YouTube

I'll try to do another video with some 3D flying outside this WE !

The gear is a press fit on the shaft once you align the flat spots on the shaft and gear it should just push on. I had my motor srews come out today the motor just pulled away from the main gear. You have to remove the two servos in front to get at the scews. Lucky I ordered extra screw kit for this. I had to put two new screws in with red locktite. I wonder how well the nano tech batteries work it would be nice to have just a little more power.

My motor screws also cam out after a few flights, and I also luckily has ordered the spait screw bag and used loctite to put them back. Since no problem.

I agree a little more power would be nice, I find it bogs a little too much in flips and so. Still, it's incredible such a small/cheap 3D 3G heli can even exist !

The 180 Pro is a good little heli - the best small heli I have flown but it has been a while...

I have crashed mine a few times now with no major damage but I am probably quite quick on the throttle hold.

If you strip a tooth off one of the servo output drive gears in a crash etc you may get away with opening up the servo and rotating the output gear on the metal pin through 180 degrees. The output shaft is a press fit into the output gear - it has a texture (knurling) to stop the output gear from rotating on the shaft. This was my only damage after a roll into concrete. The other end of the shaft has a flat that locates into the servo pot. If you don't understand this just buy a new servo! Do it at your own risk, It could cause you to loose control of your heli...But if you are desperate, stupid, tighte etc, maybe worth a go.

As with all helis there are good points and bad. The skids and main frames flex too much and the tiny screws are weak and easy to loose. The radio works well but is not too easy to understand.

I am considering jacking up the rear or the skids to get the tail blades and skid clear of the dirt. A carbon main frame and battery tray would be nice...
