hi


i currently have a kontronics 600-15 motor with jazz 55-6-18 controller, i fly 5S3P TP packs what would be the best motor to buy for more power as i find the 600-15 just lacks a little .

thanks for any replies in advance.

regards mark

My first Logo had the '15' in and was running on 12 cell NiCAD packs and lacked power too.

The last Logo I had ran with the '17' motor and 4s LiPo's and rocked! OK, it didn't give me the kind of performance that 'The Box' would've unleashed but it was plenty for me to chuck it around a bit .

As you're running with 5s then the '17' will certainly give you a hike in power and I don't see the controller suffering for it either.

Cheers
Richard.

hi rich

i think skyline wanted about £150 for the 600-17 so i might get one!
by the way i got a seperate BEC and one of those lithimons for it , not had a minutes problem cheers for the advise!

i find myself flying the 10 over the raptor 50 and the NT so i am looking to squeeze a little more from it just to make it even more inviting to fly im sure the 600-17 would be the ticket.

Check Tango 45-10 (it is $219 at Tower with their 10% discount). Ideally you should run it at 6-8s but even at 5s it should be better than 600-15.

Hi Mark
You have 2 options
(!) Go the 600-17 route, mune ran like a POS on 4S4P but it should perform much better on 5S3P
(2) Keep the motor and run 8S1P of the new 3200 cells, unfortunately you'd need to change your controller to a 40 -10 -32 .. then you'd need a BOX but that thing would rock.

The Tango would be a fair option but 5S3P is a bit low, however with a big enough pinion you'd be good, depends what HS your shooting for.

Mine comes alive at 2000

hi

reesy i would prefer to use the pack i have rather than buy others for the moment at least . i reckon i have a headspeed of around 1800 (14T pinion) not had the tach on it yet. if i got around 1950 - 2000 i would be well pleased , i reckon it would be proper!! so are we agreed 600-17 is the way for my pack ? i have 13T 14Tand 15T pinions which would be the best bet on the 17?

thanks again mark

I would prefer Kontronik Fun 600-18. It consistently gives me a headspeed of 1700 with 12 cell GP3300 and around 1800 with 4S3P's. I use 14T pinions. Fun 600-17 will also do a good job, but 600-18 would provide you with plenty of power as you progress to 3D flying.

hi SBK.

i thought about the 18 but wasnt sure if my controller could handle the current . i 3D the 10 on the 15 in a fashion it just lacks a little on stuff like tick tocks . my 5S pack gives me 21.5Vapprox fully charged and i get a decent headspeed but as reesy says 2000 would me more like it!

Looking at the KC spreadsheet 45-10 even on 5s has lower rpm drop than 600-17 (at 200w/lb), 600-18 is close but still a hair worse than 45-10, yet Tango has exceptional hover efficiency as well and a build-in fan. You need a big pinion for Tango (which is not bad by itself - less gear stripping).

You can also put "the box" with a hot wind B50 (11L or something). This would leave Tango in the dust on a 5s setup.

hi

if i was to go down the BOX route and fit a hacker what would i need to complete the conversion would the controller still be man enough etc,
also what sort of cost is the BOX and respective motor?

if i decided on the tango what size pinion gear would i need and what sort of duration should i expect

thanks for the help guys i have KCs spread sheet off reesy but it really dont make a lot of sense to me , i'm a plater not a sparky

cheers mark

If you are into hard 3D and want to keep your 5s packs / controller go for the box. Gary (http://www.tppacks.com) will set you up. Search for Gary or Dana posts here or on rcgroups. What the additional gearing in "the box" does is it allows a low pole count hackers to run at very high rpm where their efficiency is much better at 3D power levels.

If you are into milder aerobatics and high duration 45-10 will work fine and will be a less expensive upgrade. 45-10 will have as good duration as your 600 (for the same headspeed). Pinion size would depend on headspeed target and whether you use governor mode. When I get home I can check KC for the pinion size you need for something like 100rpm higher HS than your current setup.

hi

well i arnt any 3D master but i do enjoy slinging it around and as i said the 15 is lacking a little, if i could reach a 1950-2000 head speed it would be worth it. i fly a 100% flatline in IUP1+2 if thats govener mode
and i get about 17mins constant flight time flying mild 3D.

does the box add much weight?

It does but the efficiency increase from taller gearing seem to more than compensate for it. Do a serch for logo+10+box in rcgroups and logoheli BBS you will see tons of info and can ask people involved.

I am certainly biased - I like Tango line. It is super efficient and costs less than B50+the box. You have to realise though - no matter how efficient the power system is the FF and hover time at 2000 HS will be noticeably lower than at say at 1700.

hi

ive been on rc groups and had a read of many posts to which i found one where gary says on 5S3P the best setup would be 600-18 13T pinion without going HV . are 600-18 still available or is it now only the 600-17?

5S is a little low for a BOX the idea is for HV setups spinning at 40k, personally I'd be very inclined to go with the tango.

Fun 250gm
Tango 300gm
Box ? maybe more than 50gm?

FWIW I have now got 2 tango's a 45-09 in my logo10 and a 45-07 for my 3DMP not yet flown

Skip the 600 go for Tango. It is actually 286g on my scale. For 5s I'd recommed 45-10 (is the 45-15 even available ?)

BTW the box does not require HV, all you need is a hot wind motor something like B50-11L to get rpm up, 5s is not bad at all.

45-10 with a 20t pinion is equivalent to 600-15 with 14t, so something like 21t should work nicely. 600-18 seem to be a bit too hot even with 13t and may need to be throttled down. 600-17 is about right with 14t and has decent efficiencies. But tango will run cooler

45-15 is available but is very high amp draw.

45-10 on 20T or thereabouts sounds fine

Reesy -
Looking at the numbers 45-15 could be a superb hard 3D setup on 5s similar to 45-08 on 10s. No load power (not the current) should be close to 45-08 on 10s. PWM ripple current will be higher but his 55-6-18 is the recommended controller for 45-15 and should work. He will be on the rising slope of efficiency curve (a bit less efficiency at the hover power level and peak efficiency at 3D). I do not see why not.

Hmm
not convinced
KC gives 16 cells as 18.4V and 5S as 19V so your allready over the recommended cell range, then if at any time in the future he wanted to go 6S - 8S ...
Seems to be contrary to the whole HV philosophy
(I looked carefully at the 45-15 a while back)
Also availability, 45-10's are relativley easy to get hold of.

Either way I think we're agreed it would eat his current setup for breakfast
