What ESC

[leckylee]

Ok I don't really know the science about the right esc to use so here goes.
I need an ESC for a TREX 600 with a Scorpion HK4025-630KV motor and i was hoping to run 12s.
Any help would be great and any help understanding the science would also be most appreciated.

Cheers guys

The Jive 80hv would be my choice Lee,thats what i run in my 12s Logo 600.

They have a very good BEC so you dont need a seperate lipo to power the radio.

They are quite expensive new and dont pop up second hand very often and its clear to me why.

If you go for the 12s setup would look forward to seeing it.

[leckylee]

Thanks Chris
Sounds good but what is the difference between the HV and the LV?


Lee

[ChrisB]

The lv (low voltage) is up to 6s the hv(high voltage) is up to 12s

[leckylee]

Thanks Chris that makes sense

I would also recommend the Jive 80HV
Absolutely the best governor (IMHO) and bullett proof build.
The only other one I would have considered would be the Castle Creations 85HV or 120HV.
They are cheaper, but I have had 4 85HV's fail, so wont use them any more personnaly.
They definitely dont cope well with any static hits.

While the Jive's have developed a status, they lack the following:-

• Computer interface - not developed, requires fiddly jumpers to enter setup,
• End user ability to upgrade firmware - has to be returned to Germany,
• Graphical configuration - not developed,
• Limited configuration option - by stick and bleep commands,
• No 'user friendly' governor function - Castle Creations has 'set rpm'

Basically Jive's are twice the price of Castle Creations esc's and lack many features of competitors.

I have 4 Castle Creations esc's running on 3s 450, 6s 500, 12s 600 and 12s 700 with hundreds on flight per model and no issues.

Many esc's failures can be the result of a configuration error.

What model was the Castle Creation esc's installed upon?
How many cells were the packs?
What was the continuous and burst rating of the packs?
Which motor was the model running?
What pinion was this motor running?
What was the firmware revision of the esc?
What was your esc configuration?
Was the esc configured for fixed end points or governor?
Which governor mode was used?
What was the governed head speed?

They definitely dont cope well with any static hits.

No electrical component is resilient against static.

If you had static issues, presumably the result of a belt driven tail, the poor grounding of these electrical charges would have been the cause of the electrical failures.

Cheers guys i guess we all like different thingsfor different reasons.
the 600 is a TT so the static isn't an issue.

Any ideas on lipos make/mah, for this size of heli?
i had a 600e before that was running 6s (a bit lame i know) and i had 2 5000 mah and they gave me about 6 minutes. but using two of them on a 12s 600 may be a bit weighty???

*Jumpers hardly fiddly, but yes, theres no pc interface
*Yup, has to be returned to Germany, and costs £20 to do it.
*Graphical Configuration?
*I definitely wouldnt call the configuration limited. Practical and simple maybe, but they are such plug and play items, theres really no need to mess with them.
You can buy the programming card to alter virtually all the parameters. I have the prog card 1 and 2, and have only ever used it to set the output voltage of the BEC (Something the Castle creations doesnt have)
* Kontronik has its own version of set rpm where it will compensate for the quality of your batteries. 80% ESC setting on a tired 20C pack will produce the same headspeed as if using a new 45C pack (Although you would be able to bog the knackered pack, but thats the same on any ESC)

I have 4 Castle Creations esc's running on 3s 450, 6s 500, 12s 600 and 12s 700 with hundreds on flight per model and no issues

And I know of others with no problems, but I also know I had no success on 3 different models. 2 belt drive and 1 TT drive model, so for my own peace of mind I will choose not to use them.

Basically Jive's are twice the price of Castle Creations

Not true, we need to compare like for like really.
£179 for a 110HV CC and £237 for a Konny 80HV (which will happily do 110 amps all day). Factor in the cost of a good BEC for the CC, something like the hercules at £49 and the price difference is within £10.

At the end of the day its always going to be down to budget and personal preference. I just prefer the quality and ease of use of the Kontronik, and genuinely believe the slightly higher price tag is well worth it.

All the above is just my own humble opinion though

2 6s 5000 packs is only for a 90 size electric

You want 6s 3000 to 6s 3600 packs,Richy from Concept Copters has a thread on here about his one.

I am unsure what space limitations the Align airframe gives for size of packs.

Something like this??

Those sort of ones yes Lee,i use the Turnigy 6s 3300`s in my Logo 600.

Those ones on Ebay are a bit expensive,they will be cheaper from Hobbycity directly either their Hong Kong warehouse(with a risk of charges) or their German warehouse of course with no charges risk.
