e-JR Voyager E > Hacker C40-12S Brushless + Hacker Master 48-O-Heli for VE

Hello Everyone,
I bought the above combi to upgrade my VE. I had no knowledge and went by the sales pesrons advice. Now I am not sure this will work on VE. Before I use the above I want to be sure it will work. Else I could return and exchange for the right brushless & ESC combi for VE. Has any one used the above on VE? Is there a right pinion with which I can get it working. Will it work with 3cell 2250mAH Lipo packs? What about using 4cell Lipo Packs? If it is better to return & take exchange, what other Hacker motor and brushless combi can I take? (As I am offered exchange to other hacker model only)
Thanks for your time & advice
Regards
Ranna MV

C40 8L or 9L those are the brushless motors that the VE uses.

Also 3S 2200mah lipos might not be the best for this chopper, what is the C rating of the lipo?

Better to run a 3S 4000mah or 4S setup

Thank your for reply & Noted. The 2250mAh 3S Lipo Cells are rate 12C continuous & 20C Burst. will it work? If buying a new Lipo pack solves problem as it is easier than sending motor back to other country and getting it back. Can you help me explore possibility of using this combi with right pinion & Battery pack as exchange will take a months time.

The Motor rated at 3500 rpm/V and controller spec says it is 4-10 Lipo. Does that mean I cannot use 3S lipos? Also it says No BEC. Do I need to Buy a seperate BEC? If so what should be the output current rating on the BEC for VE? I am using GYRO401 with 9253 and JR DS-811 x 3No. The Controller is rated at 48A continuous current, I guess thats fine. I presenlty have 15teeth Pinion.

Thank you for your reply & regards...

Also what is difference between the S and the L variants on Hacker C40 Series motors. Is it the length? the S looks short and L long

Any specific reason to recommed 8L or 9L (L series) other than the rpm over 12S (the S series)?

Hello Mr. Hoverdown,
Sorry for asking too many questions.

Will my controller go with C40-9L or 8L, Or Do I need to change that as well. If so, What other hacker controller is best?

Regards

Rana,

Your 12S motor will work with the VE but isn't the ideal combination. The S series motors tend to have less torque than the L series which is why the L is generally prefered. The 8L motor with it's slightly higher KV and its much higher torque represents a better match to the VE airframe but as noted above the 12S will work just not as well.

Your battery choice really needs to be looked at carefully. The VE can pull some serious amps when you start to toss it around and a 2250mah battery with a 12C capability is only going to be good for 27 amps continuous which the VE hacker combo can easily exceed. The 20 amp burst isn't going to help much since it's a limited time capability and you could easily be over the battery's continuos limit most of the flight if you do much more than just hover. I'd look at a 3s3p 4000 or 6000 as they seem to work nicely in that combination.

I've used the Ultimate BEC for some time and have been very happy with it. Sorry I don't have a web site handy to point you to but a search should turn them up pretty quickly.

Hope that helps,

Thank you Ralph W.
Noted your comments on the motor. As far the battery go those are what I already have with me which I am using on EP Plane. I thought I could try with them. I can buy any new lipo that will suit the 12S (or the 8L if I replace). What if I use 4S2P or 4S3P 4000> Lipo with C40-12S? Will I be able to get performance close to 8L? Any specific make or spec you recommmend the most?

I did check on Ultimate BEC. But this time I have to stick to hacker for reasons explained earlier.

Thank you once again,
Ranna

Any comment on the controller please...

Combo to die for is C40-8L, Kontronic 46-8-12 ESC, and 3S3P LiPo. I use the built-in bec..

Also it says No BEC.

Ranna,

My impression of the above quote was that the ESC didn't have a BEC. If the controller is an "Opto" then it doesn't include a bec and thats why I recommended the Ultimate BEC. I can't think of ANY reason why a speed control with a built in BEC would prevent you from using a seperate BEC, you disconnect the power connection where it connects to the servo plug. Thats what I did with my Hacker HeliMaster 40P ESC.

As for the battery, if you don't have adequate capacity you WILL cook the battery and have to replace it. If my memory serves me correctly (always a question these days as I get older

) the Hacker/VE combo will pull between 28 and 35 amps for most sport flying and will have occasional bursts to the low to mid 40's. This may be slightly different with the 12S but should be close. A 4000 mah battery with at least a 12C rating (15C would be better) will give you reasonable coverage without overstressing the battery and either shortening it's life a bunch or causing it to cook which can result in a loss of the whole package.

My personal preference is still the 3S3P at around 6000mah. Plenty of headroom and nice long flights without being too heavy.

Hope that helps,

Ralph W.

Mr. Ralph,
Sorry about BEC. The ESC Does not have one. I need BEC. it was a mistake.

thanks for info on battery. I will go by your advice. But the present controller (48-O-heli) spec says 4-10 Lipo, Does that mean I cannot use 3S3P as suggested by you without replacing the ESC?

Mr. OldBoldPilot,
Noted & Thanks

I'm not sure about the use of a 3s pack with the ESC you have. I'd suggest emailing Hacker at info@hackerbrushless.com and ask them. They can give you a definitive answer.

Thank you Ralph,
I would like to summariase my understanding with above discussions as follows:

1. Ask for exchange to C40-8L or C40-9L with Controller 40-B-Heli. Use the built in BEC. Get 3S3P 4000 to 6000mAh 15C or higher rating Lipo. Use the existing 15teeth pinion.

2. If I am unable to get exchange for whatever reason, I still use C40-12S motor & 48-O-Heli controller VE. Get 4S2P 4000 mAh Lipo as controller needs minimum 4P. Work around the pinion size to get the right rpm and current drain. Buy additional BEC.

Kinldy let me know if I have missed anything...

Thank you all once again.
Ranna MV.

Hi Ranna,

With your controller, there is no problem with 3s3p lipopack. You can add an ubec with your opto controller.

have a good day

Hello,
I spoke to the hobby shop and they have C40-9L in stock, so I exchange the motor for that.

They do not have the 40-B-Heli but the following Hacker Controller:
1. 40-3P-Opto-Heli
2. 48-O-Heli
3. 48-O-Flight
4. 77-O-Heli
5. 77-3P

Could you help me choose the right controller please....

Ms. Libellule,
Thanks for the input.
