Discussion XeroG 700 EP I couldn't help myself!

[Albig]

Christmas came a little late this year but boy was it worth the wait.

Got me a new XeroG 600 EP to play with and what a machine.

This is one really nice kit. Everything is well packaged, beautifully machined and finished.

I'm going to try a bunch of different power systems on it to see which really turns my crank!

This thing is really cool. It's light weight and strong as hell. The packs are easily carried in the relative security of the inside of the frames. Or if you'd like to run an outrunner or an ORK or other medium RPM motor they can be bolted on from the bottom to the battery plate's adjustable slotted mount. You extend the shaft up to the bottom bearing of the transmission that's adjustable as well. in this configuration you mount the packs up high strapped on top of the battery plate and to the front of the frames just like a plastic eCCPM Raptor conversion.

You can run a R/90 95T, 94T, 93T, or the 85T and 86T R/30/50 main gears easily giving ratios of between 4 and 24 to 1, making easily adaptable to virtually any power system.

It's compact with a simple direct eCCPM mixing utilizing a new complete swashplate that is pretty cool. They got it just as short as the TT swash's overall height which is comparatively shorter than all the other upgrade units I've seen. This lets it get a lot travel about 24*, and it rocks further. It also has the inner balls extend out further than the stock ball while retaining the same diameter on the outer balls. This overdrives the rotor head for greater cyclic than you can get with any other swash.

Everything you could possibly need and then some is included in this kit, including a lot of extra stuff like CF tail fins, wire holders, Gyro mount, RX mount, slotted battery carrier, every conceivable bolt, nut, ball, spacer and the neatest little threaded servo mounting blocks. A lot of though and hard work was put into producing this professionally packaged kit. If you have a Raptor sitting there already built the conversion will take a few hours. And if haven't flown a CF raptor you'll be in for a real treat.

A lot of you know I've been flying my own CF Raptor for a couple years now. It is no more. Now it's swinging some 700mm Rotortech blades with a 32-3.

That's my plan for this baby here. The 700EP

Tomorrow it goes out to the field for it's first real flying. Got it dialed in yesterday but the wind was seriously rude so I packed it in early, came home and changed a few things around. It's ready to rock and roll!

The AUW came in a 7 lbs 12 ozs with 10s2p PLs, and this is with no help other than CF boom supports and the XeroG Canopy which is less than 4 ounces

Tomorrow's motors will be the 1515 2Y for baseline comparisons since it is the reigning drag race champ. And the 1912 1Y with fan. Both of these will of course be using the primary transmission.

The next motors will be the 1912 1.5Y versus the 24-4 Actro on 10s2p 4200s mounted up high.

After I get done with these I'll put my Hirobo EVO head and stretched tail on the 700EP and see what it will do with a 32-3 versus the 1521 1.5Y, and maybe I'll give the Actro a little help with the RPMs by going 12S. I'm going to find out if the primary reduction gears can take it or not in a 700mm application.

I'll have some FDR #s from the first 2 motors this weekend!

I love hearing good reports liek this. I just got my 600ep kit earlier this week, but haven't had a chance to work on it, had midterms, but now I'm free. 700ep.... I've been wanting to get a 700mm disk heli. I also got the xero-g canopy... I'm going to be running my standard, 1515/2y,jazz55, 10s2p setup, and see how she goes...it had enough power with my current e-raptor, with the glow xero g frame, so it should only be lighter and better. I'm thinking in the next week or so, molding my own cf landing gear. I've been molding a lot of think recently, and I think I can create some pretty nice gear. picture joker gear, but one piece, and lighter

I have made a few flights with mine with an 8s LiPo (10s are on order). The best thing is that you can very easily change the gear ratio with lots of choices. The Box is much lighter than the old conversion kit for plastic Raptors. This thing is very light and incredibly strong.

The control system feels a lot better than my buddies XeroG IC Raptor 50. This thing flies so well that I don’t think I will be changing much.

I am using a Neu 1515/2Y and one of the latest Phoenix HV-85 ESCs.

[Albig]

Yep RC it's pretty much all there as designed.

I have just grown to point where a 700mm disc is what I like.

They just have a feel to them that no amount of power in a 600 can duplicate.

They're bigger, quicker and more precise. You would have a hard time believing the difference in feel between the 600mm Raptor head and the 700mm EVO head.

The neat thing is it would take about 30 minutes to change rotorhead and tail boom parts between these 2 helis for a 700mm. With Everything included you'd pay about 900 bucks for a CF framed 700 kit if you went that route. Truth is the difference in price between a 600mm and 700mm E heli is negligible. The packs make up the bulk of it, and that will change dramatically over the next 12 months.

Looking forward to seeing how this fan cooled ORK 1912 1Y stacks up to the 1515 2Y. I flew it once before on the UE and the power was very respectable.
If the fan works well it's going to be a real competitor for the 2Y.

The genius of this design is how they used the Boxes case as an integral frame member that would have been necessary anyway as a motor mount. And if you remove the gears and go with a lower speed motor you won't be carrying any unnecessary weight. I have one of the original Box prototypes and I can tell you this new one hasn't missed a Jenny Craig meeting yet

Off to the field

Hmmm....

So is the "XeroG 600 EP" a whole heli or just a kit to use on a Raptor? I think I'm reading that you need to have a Raptor but I'm not familar with these "kits"! That thing looks incredibly tall, what's the height from skid/ground to top of the button? One last question, "What kind of flight times can be achieved with a 10s2p and is this kit/(conversion, If you need the Raptor!) cheaper than the other 60 sized electrics? I sure would like a really "big bird" (Read not a yellow-don't-know-how-to-shut-up-Big Bird! LMAO!) to piddle with till I'm more (ahem) of a threat to Alan and Dan Szabo! ;-)

Very cool

Al, Are yoo going to use a Torque tube or a belt with the longer boom?

I realy like the idea of stretching my Raptor not a Xero G thought but an SE ; The 690/700 disc is way more stable and smooth than the 600.

The kit as sold now is really a conversion for an IC 50 Raptor so you would need an existing Raptor or have to purchase a kit or the additional parts.
It includes everything in front of the XeroG box in the first picture.

Like most CF frames they are incredibly tough and for the most part crash costs will be for replacement TT parts, boom, shafts, rotorhed stuff etc.

Thing is wouldn't be too hard to put a package together that would have everything necessary to assemble a 700mm heli and it would cost about the same as the kit with a new Raptor 50 SE kit.

I'm going to stay with the belt for two reasons. One, it works fine! I've been running a stretched boom / belt now for about 2 months with no problems. it's one smooth working mechanisim. My UE has less vibration than my Joker does. It's a most excellent AP platform.

Two, it's THE most crash damage resistant transmission you can get. Don't ask me how I know this

The other belt drive options such as the Joker's and EVO's have a small counter gear and shaft that invariably self destructs on boom strike crashes and they usually take the TR drive gear with them. The torque tube drives usually require a new tube and they usually take the crown gear along as well. More often than not with the Raptors mechanics all you'll need is a boom. It's even rare that you'll destroy the belt. The design is simple, elegant and functional.

OK. Now I gotta get me one. I told myself, "I don't need any more helis. Just fly what I have". But noooo. You guys go and do this. Now I need one too.

[chuckhager]

Just a thought. I'm only familar with the R50's, but would the head & boom assembly from a Raptor 60 work with this kit?

[shades]

what is necasarry to get a r50 running a torque tube? i love my joker and all, but i just want a heli with a torque tube, it would make a great auto machine.

and for the 600ep, how do kontronik tangos do? i've got a spare 45-07 looking for a heli.

Great stuff Al. Thanks for breaking trail again and sharing. Looks like you'll need to revise the slogan under your avatar "Xero G WannaBe" just doesn't fit any more.

I think a 1521-1.5Y on 12s2p-4200 in your streched "700ep" version will end up being the new drag race king-of-the-hill.

If Steve does a fan-equipped 1915, that should come close to matching it, I think. In the Ion tests we did on 12s, the 32-3 does very well, as expected, but the belts we were using would only last about 9-10 flights before they shread. We were hitting 3600-3700W peaks. With the 1521 on 12s, the belts only last until the first time you try and "pop" it, which was a bit over 4000W. The belt comes apart immediately. I think Dana calculated once that the "box" gears are good to about 6000W, so it should be able to handle the power. Should be fun!

Al,
Could you post the part numbers you are using for the belt and boom?


I already have several old Hirobo heads that might work so all I need is a boom and belt.


Thanks,
RC

[Albig]

RC, I'll make up a list of what it takes. It's real simple!

I flew both motors today and that 1912 1Y is AWESOME at 29,000 RPMs it out torqued and hit higher peaks than the 1515 2Y. It just clearly out pulled it and it stayed about 155* max with the fan.

I'll be getting the #s emailed to me later.

I want to fly them again back to back with the 4200s next!
