The absolutely STOCK Hornet II totally rocks. I both flew it today and watched Eric Larson do things I have NEVER EVER seen a Hornet do - and I am one of the original Hornet guys and BIGGEST Hornet bashers!

How about this... Curtis takeoffs - fully pegged negative with PUNCH, BACKWARD INVERTED funnels with a big-ass diameter and NO tail wags, TICK-TOCS (both elevator and aileron) stationary. Backward hurricanes. Oh yeah, and even I did boring, endless forward and backward tumbles with zero loss of altitude, tail control or headspeed.

If I didn't know it, I'd have sworn it was a Fury 60 or better I was watching.

Now when I say stock, I mean the machine itself, not the gyro or motor. He has a Hacker 20-22, Schulze speed controller and GY240 - but other than that - that's IT in terms of 'upgrades'. Don't bother even cutting off the weight of the 240 - the hacker can handle it - so just shorten the wires on the gyro. These aren't really even upgrades as anybody that really flies 3D knows that no motor that costs less than $10 is going to hack it like the stock 300 and that anything but a Futaba gyro is a waste of friggin' money (sorry everybody else that makes one - but it's true).

He's also flying with an e-tech 11.1V lipoly battery. The lipoly's are a MUST as is that voltage for hard 3D. Now if you are just learning, I'm sure the stock, stock machine will be fine - but the motor, gyro and battery setup as above is needed to get the most out of any of these machines.


What was that line from the Godfather? "Just when I thought I was getting out, they pull me back in!" Yep - here I go again.

I will be taking vids this weekend and posting to prove it with Eric at the sticks.

Eric,

Have you found adjusting the tail a problem? I understand MS composite has admitted the hard to control/adjust tail rotor for the Hornet cp.. Has this been cured with the Hornet 2 kit?

Eric,

I moved my servo the tail as you did, and now I am getting some vibration. Any idea's about how to get it to smooth out???

Moving it to the tail also makes the machine want to go to the right badly now...


Thanks

Darrell

Nice write up on the Hornet build Eric. I'm going to be having a go with one soon. Why is it you say 55's on the cyclic? is this due to the torque and slop of the 50's? I was gonna go with 55's but ended up getting a good deal on 50's. Hopefully the V2's tail holds better then my Pics and past V1 Hornets


Btw, your 9C settings..think they'll transfer over to my 9Z?


Thanks man

Thanks for the info, and as you stated the main blades are once again out of track. I will work on this today and post afterwards. This is the third time for re-tracking the blades, is there something I'm missing here? Could this be from setting the blades too loose or too tight?


Thanks

after reading this post, I'm leaning towards getting a hornet II instead of a regular hornet cp. I just have a few questions. is the tail assembly(gearbox, gears, etc) and main rotor assembly and shaft interchangeable with the first hornet's parts, aftermarket or spare?

One thing that is keeping a dead decision on the hornet II is the fact that its a little longer than the first hornet. I would like to put a scale body on my heli eventually. Do you think there will be scale bodies made for this heli in the future? or would it be a custom job?

Thanks and happy holidays,
Keith

The hornet 2 is awesome! Very stable and most importantly a joy to fly.

From my experience with the CP Hornet, I'd say that MS should make some larger tail blades out of stiffer plastic. No.......I don't want $25 carbon ones.

Thicker OD on the tailboom and totally redesigned main blades seem to be the biggest and best changes - making the gyro FINALLY efficient (a 240 or 401 that is - forget the other ones).

Sample vid clip is coming by weekend with Larson on the sticks and me at the camera.

Anybody that has a brushless set-up and a governed speed control on a Hornet should try this little experiment during their next rebuild. Don't install the mainblades and the tail control rod/link. Run the tail at operating speed. Now move the tail "L" link to control the tail blade pitch. Notice how hard the link is to move throughout the range you think your servo is going to move the linkage. IOW, setting up the tail pitch range statically isn't really going to give an accurate account of the pitch range that your tail servo is going to be able produce while flying. While your doing this experiment, put a lot of pitch in and stall the tail blades (your servo doesn't have the strength to go there). Watch the tail go wacko. IMO, it's not the friction of the threads/hub that make the tail linkage hard to move. Rather, it is the fact that the blade bolt hole is in front of the center of pressure for the tailblade. This results in a lot of force to put more than a small ammount of pitch in the tailblades. They just want to fly at 0 pitch. That's why I want slightly bigger, better designed, and stiffer tailblades.

It also doesn't seem to be helping that the slider is being pushed from one side. With enough pressure (blades wanting to stay at 0 degrees) you really put alot of stress in the assembly.

My hornet flew great when i first built it three weeks ago. I could get 45 procent gain without wobbling. Now I can't even get 25. First I thought that it was my flying getting better, trying more things and thus needing a better tail and later on the tail wagging could be overcome if the headspeed remained high enough. Now even that doesn't work anymore.

My hornet only has about 40 (crashless) flights but the pitchslider and the lever are now completely worn out. The conical hole in the lever is worn out and there is a distinct hole in the little stick on the slider too.
I am now in the proces of building a new mechanism wich, i think, wil greatly improve the tail slop. When the first prototype is working (1/16 ply...way to thick to keep) i amhoping to post good results.

The hornet two tail supposedly's much better...What exectly is the difference. The longer tailboom momentum? The support booms?
I gather those are the only real (not esthetic or userfriendlyness) changes....right?

Not sure which Hornet you have but the tail on the Hornet 2 has a metal tail rotor shaft with preinstalled blade hub. The pitch slider is double wide with two blall bearings and has a screw on brass insert that holds the pitch slider ears to it. The tail boom has a larger outside diameter around 7.5mm. Inside there are 4 bearings supporting a music wire metal drive wire. My tail is smooth with no vibrations. In fact my whole heli was vibration free right from the start. It was smooth even with the blades 1/4" out of track. I haven't balanced anything yet either!

I have a hornet I, the second generation with about the same tail assembly as the cpx and the II. I can't wait to see some of the video's especially the eric l. one because i saw what he did (we all have, probably) on the red cnc head movie on HH.

My previous post wasn't so much what is different but more why does the extra stuff....

Mr Magoo - I agree with your assesment of the hornet tail rotor blades. I made a set of blades, with the goal of moving the center of pressure forward compared to the stock blades, and also to reduce the weight of the blades, which in turn reduces the tension (and hence friction) on the tail rotor pivot screws. The blades worked, I would say the force required on the tail rotor bellcrank was reduced by about 15% or so. Vibration was also reduced.

Try making a set or two, 1/32" plywood works great. Just double it up at the root, drill a 2mm hole, and harden the hole with a little CA. It works fine for me, with quite a few flights at 2400 rpm headspeed with the speedup gears on the tail. I made mine with a slightly narrower chord than stock, and a mm or two longer than stock, so the total area is about the same. I put the hole at about 50% chord, but now that I think about it, 30% or 40% would probably work even better.

Dave:

Do you need to cover the ply blades or seal their edges with CA to keep them from delaminating at 10k rpm? It's good to hear from someone with similar experience to my own.
