I ordered an Aeolus 50 3D CF last week and thought I'd post some pics of a few things. I'm very impressed with the design so far and the build has been really enjoyable. I've been out of the hobby for the last few years but the current equipment that is out there drew me back in. I'm going to set it up with 2s unregulated cyclics and I'm trying to decide on going FBL or just run an AR7100R with a GY520. Most likely I'll go standard for now and convert to FBL after a few months.

So my overall impressions so far (still have to build head and linkages) is this is a fantastic design. The quality of the parts has been top notch. The only issue I've had so far is the tail rod lever support (that mounts right below the torque tube drive module) didn't quite fit in the frame. I had to shave off about 0.5mm of carbon fiber with a razor and it fit right in. So far every pre-drilled hole and lined up perfectly.

Anyway I'm not gonna post step by step build photos, but rather some of the things I've found (so far) that have really impressed me about this design. I'm also working on a timelapse build video I'll post up.

Just an overall shot for reference. The first serial numbered heli I've owned :-)

I love this.. inspection holes for the torque tube drive gears, pin and easy access for link pliers to the tail rod linkage!

Note the fuel tank protected from the frame by rubber. Kit also included 2 fuel link shut-off clips. Third bearing for mainshaft above tank.

Another kick-butt design feature.. the skid struts hold the frame spacers for easy install/removal of the skids. The engine will come out without removing the skids also!

Nice tail rod guides with bolt and nut.. Also note boom support X bracket included with kit.

Super clean tail box. Very easy to work on this tail.

Awesome, love my kit right now too.

Did you get CNC grips and button?

04-10-2010, 11:20 PM
I've got whatever grips come with the CF kit.. I think they're plastic grips, metal hub and not sure about the button. Haven't opened that bag yet :)

04-10-2010, 11:59 PM
I think you got the CNC parts, there are two levels for the kit, the GF with majority plastic and belt or the CF with TT with CNC grips/tail/button.

I'm debating to get the AHF grips and button in CNC when I can, and toss on Align CNC bits for the seesaw/mixing arms.


Go the alternative route and toss on a Kasama/Avant/Outrage/Guai head and tail. I'll be sticking with the Belt, I'm not a TT guy, my flight ground is quiet uneven and I kill belt's on my 250's non-stop. LOL

I couldn't sit easy with the extra $30 in repairs for more gears on a consistent biases.

Wow this just keeps getting BETTER! I just looked in the bag and you're right.. CNC grips.

Nothing wrong with a belt drive.. they are certainly more forving to those unplanned tail trenching sessions. Lord knows I split many pair of NHP tailblades on my raptors and never had to replace the belt because of it! Well, maybe once LOL.

I thought i would show a pic of a new canopy design idea

05-07-2010, 12:13 PM
:shock: Where do I put in my order for one? That's NICE! :D

See Chris at AHF-USA

I think he meant where to get a canopy, he has an aeolus listed in his sig.

05-08-2010, 11:49 PM
Um, yeah I was referring to the canopy, I like it, I want one like that, so if it's custom and you did it, name your price.. LOL :P

I got my own Aeolus, I <3 it. :D

05-08-2010, 11:51 PM
By the way ZZ, you'll wanna get CNC cyclic arms and tail blade grips. Those plastic goodies snap like tissue. :P

05-10-2010, 05:52 AM
Sorry Mike, didn't read your sig. As for the canopy it is a trail product at the moment and maybe coming out with future kits depending on build price they are sheeted with a carbon mat to make the canopy stronger. Once again contact Chris he may be able to place an order for you but I am sure it was a limited release.

05-10-2010, 12:40 PM
Oh so this is a potential production canopy? Niiice! :D

I assumed you made it or bought it 3rd party. Awesome thanks I'll give Chris an email. :D

You talking about mixing arms on the head? Are they likely to fail in flight or are you talking about breaking from even a minor mishap?

Good news on the heli front.. I just ordered the rest of my goods today so might be in the air next weekend if all goes well. Final setup:

6008HS receiver
2s 2700 Lipo
no regulator
3 X BLS451
1 X S3155 (thr) narrow style
Multigov Pro
Switchglo Pro
Radiosouth inline 5.1 v regulator on the 251 servo

So we'll see how all this does on 8v. Should be a rockin ship as I've saved weight everywhere I could (well I could have left off the switchpro I guess)l

No, nothing failure wise. The push-pull cranks for the cyclic, the first ones after the servo wheel and before the swash. Plastic ones always snap in minor blade strikes. I bough Align Trex CNC ones and modified them. :P Perfect fit on one side, the other required some cheesing. Beats buying them $10 goodies every crash/ops scenario.

That's one killer setup! Can't wait to see her in the air, videos!

05-15-2010, 04:58 PM
Ok cool...I will keep a lookout for some upgrade parts on those items. As for the videos, don't expect to see anything too impressive unless I find a good pilot to put behind the sticks LOL. But I'll be able to demonstrate the power to weight and collective response at least. :YeaBaby:

05-16-2010, 02:09 AM
No worries there, I bought two sets of HK carbon "3D" branded blades, $20 how can you go wrong? Their stiff, nothing Radix stiff-like but stiff, they'll do the job to beat-in and practice with.

I see what you mean about the arms being flimsy. I also feel the same about the mixing arms on the head. I finally got my BLS451's installed and was able to put some loading on the grips. I see metal parts in the future, although I like to have some sacrificial plastic in the path to the servos.

I've also ran into a major problem with the fan hub/clutch assy. Runout! The collet was machined off center. :thumbdown:

Also I've discovered (as others already had) that the hex screws that come with this heli are very soft and the heads strip very easily.

Having a rough go of it with this heli so far and it's not even in the air yet. I guess they're going to overnight me a new collet so maybe I'll be in the air this weekend.

05-20-2010, 11:18 AM
I've never had plastic that wasn't flimsy. Luckily, Align Trex parts slap right on, everything besides the frame components (frame sides, landing skids, frame inserts).

I'm in the process debating what to do for the head. I want all CNC. But I wanna swing away from the "Align" designed head that's on majority of models. I really wanna have a go with the Avant style head, I see them on a lot of models, RJX, Outrage, Kasama, Synergy. Something new you know? I'm trying to find a company that sells the full head for their models that fits on the main shaft diameter of the T-600, and of course isn't $250+ freaking dollars (cough Kasama). I liked the Outrage, but it's black, I want all silver, so may swing for the RJX or Synergy?

Yeah my clutch assembly was already built, I stripped majority of the screws to service and rebuild the parts. What a bitch. Ah well, otherwise the kit is perfection. :P

05-20-2010, 01:28 PM
Kits back in stock at h/k. No parts yets tho'

05-20-2010, 09:50 PM
Ah, there are many places to buy parts. :P

They were suppose to have them back in March believe it or not.

05-22-2010, 06:53 PM
Is this heli exactly you are talking about?

AHF-50 .50 Size Nitro 3D Helicopter Kit

05-23-2010, 04:29 PM
Yeah that's the heli we own and are building in this thread.

Sexy model... :D

05-23-2010, 09:50 PM
Well actually that link is the GF version which has some plastic parts such as the tail housing and main grips. The one I'm building is the CF version.

Good news from the weekend's flight testing! I'm getting the bugs worked out of it and it's starting to fly really nice. Today I had to cut short due to tail related problems. It turns out the thrust bearings are mis-marked from the factory (the ones marks OUT actually have to go IN!) so I think that will cure the tail holding issues I ran into today.

Other than that, I brought the headspeed up to 2050 and it's starting to have decent power finally. More flying tomorrow if the weather plays along!
