Vario Hughes 500E 1/4

Hi All, I'm sorry if this topic have already been covered. I've read A LOT of forums and just want to know if I can convert to eletric a 12s or 10s set up with a 410kv or 500kv 8mm shaft use the Vario Petrol mechanics 90 : 18 gear, Product no.: 1002/21 and still keeping the clutch without playing around manufacturing all the parts myself, beacuse I dont have a heli-factory workshop
I'm going to start with a 2 blade head from Vario, the one that comes with this heli (9041 hughes 500e)One thing is for sure, it fells like I have to work for NASA to work out all the amps/watts/gov setting/10s or 12s/kv/ESC with BEC and more.I've been flying Align t-rex600esp for to long I guess thats part of the fun of building but with more and more people going to electric, can Vario come up with a conversion that works, plug-in and fly
Don't get me wrong I love Vario gear and this hobby, but you look at the time that it takes people to finish their projects due to finding the correct combo and manufaturing gear and cost.
Anyway thanks for time and suggestions.

Yes. Call Joe Howard at east coast scale helis. He has the electric conversion kit for the benzin. Use the xera 300kv motor and you retain the clutch/belt drive with the kit that Joe sells.

Hi Barry,
thanks for the info, so with the Xera 300kv or any 300kv motor I can keep the 90:18 mechanics? what is the ideal head speed on a 2 blade head for a heli that size?

Nick, I had the 4 blade head with gas mechanics and the head speed was 1140. It flew very nice. I'm converting to electric using 12s and I'm looking for a head speed of 800-900. I should be able to get the gearing I need and a 300kv motor should do it

Yes, you can run any 300kv motor with an 8mm shaft (if you want to retain the clutch). IMHO, the xera is the best for this application and is a very efficient motor. AXI makes some very nice motors, but I've heard that they tend to run a little warm in a heli fuse. Not a deal breaker by any means, just something to consider. I haven't looked into any other gearing options for the benzin mechs, but I'm told that they exist. Again, Joe at ECSH is a wealth of info regarding the vario stuff. I have 3 sets of skyfox mechs, but I'm rather new to the benzin airframe and am building one for my vario lama kit. I'm going to run stock benzin gearing (with clutch), 300kv xera on 12S 5000mah and a Jive 80HV esc (with heatsink).

Here's a great site for checking motor/battery/gearing combos.

Hi Mojave,

How IS the Lama coming along? I've been wondering about it. Well, I hope. Can't wait to see some pics. Thanks

Coming along slowly, I was waiting for custom direct to swash frames that didn't pan out, so I'm back to plan A. Mechs are built, motors installed etc.. I'll pick up on it when I get home from work travel in July. I wasn't kidding, this job is freekin killing my flying/building time...

Got a couple other sources lined up Barry. I'll let you know when the laser fires up. I'm looking forward to the frames myself.

Mojave,

I'm back to travelling for work again myself, but at least it will allow me to start buying heli stuff again. Layoffs are the worst. I'll pm you some details - you'll be interested. J

No worries Chris, I'm super busy anyway. Shipping out on work travel at 0-dark-thirty tomorrow morning. If your source doesn't pan out, Mikey will probably cut them for us when I get home.

Thanks Barry for the photo. Do you know if the Hobbywing 120A are good ESC?

I personally wouldn't trust anything but a pod/boom to a hobbywing esc. Not trying to start a poop throwing contest it's just my personal opinion... A quality scale ship deserves a good esc. I'm running Jive HV esc's, expensive but worth it. If you go the castle route, buy the next size larger than you really need. It's cheap fire insurance...

The rating of the CC ESC seems to have little to do with it's propensity to spontaneously combust... they seem to burst into flame without regard for any particular circumstance.

I'm currently building a big Vario MD500, and the ESC is the only thing keeping me from getting it flight ready... Just not sure which one to trust. Even the Kontronics have experienced catastrophic (and incendiary) failure...

I am running 12s with a CC 120HV and a 5035-390kv on a converted benzine. 1200 head speed in governor mode...runs beautifully. I maintained the clutch and 90:1 standard gearing.

Doorman was very helpful and is running the same thing, mine is in a EC 145 with a four blade head...I would never go back to Petrol.

Let us know what help you need. As Barry said, Joe Howard at EastCoast Scale helix can hook you up with the conversion kit...about $80 USD.

Rodan,
thanks for your input. Like you said the ESC is the maker or the breaker/fire starter I've also been looking at the
jetspin pro 200 opto $455.00 Very over kill I know. The kontronik are very expencive compared to the CC, I guess it all comes down to luck if you get a good ESC or not, and set up.

Rckfish,
I agree petrol just dont sound nice in a scale heli. Good to hear that you have a great set up and it's all working for you, thanks for your set up info. I have ordered the hughes 500e for Joe, I'm just waiting for it to arrive.I've got the list of the gear that I'm going to be using hope it's ok,
on the washplate 4x Futaba 351 or s9255
on the tail 1x futaba 451
motor scorpion or Xera 400 or 300Kv?
western robotics BEC 10-15A
and the ESC, well finger crossed still thinking about it, i've been tolled if I go with CC to look for the V2 series.
Thanks all for your help.

If you go with the 300kv xera, you won't need to govern it down as much as the 400kv motor to get the 1200 rpm headspeed. The less you govern the esc, the happier it will run.

The Castle Creations motor we are running were the prototypes and they are 390kv 5035 size..l am running 12s with a CC HV 80, in governor mode at a 1250 hs.. 12 minute flights with plenty of room for longer if needed..no heat build up anywhere, maybe a few degrees above ambient...
KDEDirect has taken on making the motors, and they will have, I think a 350k, that is about perfect for the 90/18 gear set..and it will come with the 8mm shaft size that is needed for the conversion kit for e-power..these motors are made to work with the CC esc's

If you do go with a Castle esc, the 120 HV V2 would be the one you want..

Good Luck...Stan
