i do aerial photography using a joker, and i've come to realize there'd be a serious advantage to having a nice little heli for ap, paticularly for going to ski resorts and places where i would just want the heli in a bag.

and seeing stets use of the eolo as an ap platform made me think my best bet would be a eolo.

but i've also been wondering if its worth me getting the le? i dont really want to get the li because i dont like belt drives.

my plan is a 9oz camera(canon s70) and well i can make a light enough camera mount(around 2-4oz) would the eolo really be up to this task? or should i just get a l10(would prefer an l16)

yes,especially if you had a 4s systemfor the extra power

but would this be to much load on the frame? would it still have that extra punch to get out of rotorwash etc?

i've also been looking at an l-16, it seems to be even cheaper than a eolo LE?

Hacker C40-9L and Flightpower 4s 3700 Mah Evo cells gives awsome power and would easily carry 12oz of kit easily I would suggest. I run 15t pinion which gives a very high (3D) head speed but I would run 14t with the extra load. Some people run 14t anyway for general sports flying, so this would be nothing out of the ordinary and still fatster headspeed that the std 3s used by most.

I dont know about the differences between 3s and 4s for airial, but I think lifting power insn't measured in headspeed but torque.

If you use 3s, headspeed around 2000 a LE isn't needed. For 4s I would rather have a metal headblock, you'll run around 2600 rpm on the head.

It all depends on whats needed to lift your camera.

Search for posts by NYTurtle regarding his eolo in a BBI Apache fuse plastic toy. This thing is a tank and is very very heavy. We had a lot of problems with ground resonance blowing it up, and finally resolved it by adding a top brace to the fuse connected to the heliup upper servo holder.

My CamEolo weighs just a bit more than a standard eolo, but his Apache must weigh 5 pounds. He bounced it a bit the other day because he descended too fast and the disk could not stop it adequately. I have never had a resonance of any kind.

As far as the frame strength, I have had no issues whatsoever. I did make my landing gear a bit taller, then added a bunch of "truss" tension member bracing. Have not had any problems with chassis strength or landing gear and I have clumsily bounced it a few times off the "floats". Also, I am using the "Super Struts" Jeremy at RCHover made. I am expecting him to make me a number of sets currently.

The 4S vs. 3S power is a huge deal. All I can say is the Hacker 9L motor with the 4S2P pack has a ton more power than the 3S setups. I am using 3S because I started that way, and have a bunch of packs and motors for it. My Lehner seems really good at 2100 HS, but it is heavy and the Hacker 9L on 4S will do much better especially if concerned with weight. NYTurtle's Apache has the 4S/Hacker setup, and this system has absolutely no problem flying the beast.

I was pleasantly surprised about how well my nose mount worked, as I was very concerned that it would resonate or something. I think the JR landing gear dampers between the frame and themount realluyu worked well.

I suppose it would probably be a lot less trouble to use an underslung system, but when I had my CG lower with the battery below the tray I did get some pendulum wobbling.

As far as the torque tube setup, it is working really well with no vibration. Initially I had one of the drive cross-pins in the tube end come loose and cause glitching and damage to the ID of the boom, so I now sand these pins and red locktite them into the torque tube ends. I originally used this setup because I wanted the boom to be easily removable for travel, but given all that is on it, the removal is not a quick thing to do. So I would recommend the belt drive as it supposedly also speeds up the tail rotor, lightens the heli, reduces the parts count, eliminates adjustment of the crown gear and the tail bevel gears. You can buy the torque tube upgrade and fit it on a standard eolo.

Was flying in strong winds yesterday with the Robbe (General Laser) stabilizer and I am very pleased with it.

Finally, I am using the MAH blade because I was under the impression it was stronger. Someone with a lot of experience suggested strongly that I try the SAB blades as he thought they would be much more stable. I may try that.

i've now owned everyblade(acept for v-blades) and have decided mah to be my favorite.

stet, do you have any expierience with the spirit l-16? with the right motor etc it should be ballistic, with the current selections of motors etc anything can be powerful etc.

i would plan on putting either a tango or plettenberg and running it on 6, 8 or 10s. does the spirit run 600mm blades?

the L-16 pretty much landed flat footed on the market, not really sure why.

I think Jeremy at RCHover has one he would like to sell, pretty much all set up. There is another guy on this forum who wants to sell his too.

I get the impression the L16 is of the same size class as the Logo 10, and if this is the case, you might want to wait as I hear that Align (of TRex fame) will release a heli in this size soon, and of course the cost will be similarly improved.

My recommendation is to to with the Eolo, otherwise you are just growing up into a nitro size heli with an electric motor. It has plenty of performance, the biggest drawback is stability in wind. Other than that, it is fantastic. I am sure it can carry a small video camera. Cost is a benefit too, with half price on the motor and batteries compared to the L-16 or Logo 10. So for the same price you can have two flights (batt) instead of one.

And if that is what you want, I recommend you go all the way and get a Logo 14 since it has the driven tail, but the new Align will certainly have a driven tail so again, in that class, it should be worth the wait.

The FlightPower Evo cells are 4s1p (20C rated) so are even lighter than the 4s2p you mention, and yes, the 4s has much more power, thrust and torque when compared to a 3s system.
The other heli I would consider is a Century Swift. I have seen a prototype conversion from Real Raptors with lighter/stronger carbon frames and a few other bits and it flew superb. Can't remember what the motor/battery config was, but it might be worth contacting them and having a chat as it is a little larger than an Eolo.

Andy of real raptors is a good guy and very knowledgeable on electric heli systems.
