Torej pred kratkim sem se preko emailov spoznal s kolegom iz Švedske po nicku "NIC".

Ima veliko izkušenj tudi s pravimi avtomobili in dirkanjem in ve zakaj se gre (vozil hude zadeve --- Viper GTS , ... ). Je prestopnik iz nitro - > bk elektro in pravi da je noro!

To je njegova izjava, in gospod ve kaj govori:

Real track-test:

Car: TF-2R
Motor: Hacker B40 6L
Batteries: 8 FAUP 1950mAh
Esc: Schulze 18.129F
Gearing: 108/32~7,47:1

The acceleration is eyewatering . The punch out of corners is untouchable . I wonder if even a 1/8 track car can catch me ..... freaking unbeliveable !!!!
The rear belt started to skip just a few teeth here and there in the end of the run. But boy oh boy was it fun .
The cells are amazing . 9 min of run time . They got into "dump-mode" at 9.10 and boy did they drop fast !!! I coulden´t finish the lap !!

And now the temps:

Motor: 52,4*C
Esc: 46,7*C
Batteries: 48,3*C They wasn´t even warm to the touch !

Pros: Well......Guess !!! Everything !

Cons: None !!!! Not even one single thing ! Well...... the rear pulley for the rear belt maybe has to be changed as well as the belt itself. They wasn´t new when I tested the car so I don´t think they will skip if they are fresh, but hey............I don´t mind .

Just WOW...... That´s all I have to say

Thanks !

6 celic FAUP (bolj mrzle ... )

Now you can get a feeling of the acceleration when I put 2 cells more in there and lower the gearing by almost HALF !!!????? Hahahahaha......!!!!! Now we are talking quick acceleration !!! Like I said: A 1/8 Serpent doesn´t stand a chance in a dragrace !!! And with THAT set-up I got 9 min, THAT is really good !!! Ok the topspeed is less, only about 75-80 km/h but you don´t need much more on a track, not on our track anyway.
Still with only 6 cells and really really tall gearing (3,59:1) like in the videos it accelerate like this !!!!

I can say that the car handles really really well due to its very low CG and overall balance .
I ran it at the asfalt track this weekend and it was really quick around the track with all the power you can ask for .
It had some push the first laps but when the tempeture of the tires had gone up it was handling like a dream. Not much bodyroll and the turn-in steering was superb .
The former 1/8 buggyguys who now drives the Kyosho V-One:s and Mugen:s said with just a little bit of tweak they will have a hard time to beat me.
I think that is a good rewiew for a car that wasn´t designed to run on asfalt at all.
A overall "kick-ass car" .

pa si lahko še ogledate slike in video posnetke predelav 1/8 bugijev na elektro.

Pa ne spet zdej spet da na karbid pljuvam ipd. , samo informiram

[rcman]

Hojla

Ko prebiram to temo me je malo prijelo da predelam svojga sst99pro. Trenutno imam stock motor sam razmslam da bi namontiral gor nek poceni BK komplet. Ne zanima me toliko vecja moc kot cas voznje. Moc naj bi bila nekje ekvivalentna 17 ovojnemu motorju z krtackami.

KAJ mi priporocate?

Kaj pravite na mega motorje ki jih imajo v Mladem tehniku ter JETI regulator, ce seveda obstaja avto verzija


LP Tadej

[mihah]

Zivjo Tadej,

Te je prijelo, kaj

Torej v nasih trgovinah se nekaj najde, ne pa vse oziroma nimajo na zalogi.
Ce kar takoj naredim reklamico za Mladi Tehnik: http://modelarji.com/phpbb/viewtopic.php?t=1629


Torej pravis nek ekvivalen 17 ovojnemu.

Mega pride kar v upostev , velikost 16/15 in sicer 2 ovoja.

http://megamotorsusa.com/shopping/..%5C ... 2.htm?id=1

Ker je motor 400 velikos bos moral naresti ali dat delat vmesnik (glej mojo Aveox predelavo). os pa je 3.17 mm in bo vse lepo pasalo. Prav tako bi ti priporocal, da das gor hladilnik, ker ma motor le nizko maso (76 g) in se kljub velikemu izkoristku lahko le segreje.

Druga opcija je se malo vecji motor - 16/25/1 , ki pa se vrti ze 5000 obr/V. Ce bi ga malo "umiril" z velikim prenosom bi se slo. Vseeno motor tehta le 110 g.

Ce te res zanima mi pisi email pa se pogovoriva.

Za regulator je pa tako. Ce sedajle malo pomislim se da pri nas dobiti samo BK 1 regulator ki ima tudi program za avte, to je Kontronik Beat, prav tako v MT.

Dosti ceneje je recimo MGM (basic/profi line), samo nima avto softwarea, ma pa nastavljivo zavoro moc (zavora on off). Recimo da bi slo, ceprav bolj pogojno. Vzel bi 40 A razlicico, ceprav 60 A ne bi nic skodila (malo rezerve ne skodi). Dobis v MT ali Mibo.

Jetiji Advance so tudi zanimivi, samo ne vem ali majo tudi nastavljivo zavorno moc.

Najboljsi regulatorji po razmerju cena/zmogljivost so BK Electronics Warrior CAR s ta novim softwareom. Vendar bi moral za MEGA motorje reci pri BKju da ti dajo 30 stopinjski timing (zaradi 6 polov). Vendar ce bi potem ze narocal je se najbolje vzeti se enega Basica 3100. To bi bil res fleten combo a la 17 ovojni krtacni samo boljsi izkoristek. Vendar pa se le splaca vzet 4200 pa ga dati na velik prenos, da bodo hitrosti enake 17 ovojnemu motorju.

[rcman]

Hojla

Se grem jutri pozanimat v MT.

Ce bodo cene zanimive, se nikoli ne ve

Miha te bom kontaktiral, ko bom vedel malo vec. Moram nabrat informcije, cene in si ustvariti sliko

LP Tadej

[rcman]

Danes sem se malo oglasil v MT, ker so mi malo pokazali kaj imajo na zalogi.

Torej cene so zelo zanimive

MEGA motorji (okvine cene brez popustov):
16/15/2 19900
16/25/2 22900
na zalo gi imajo tudi
22/10/5
22/20/4 cene se mi zdijo da so nekje 22900

Pogledal sem tudi reglarje ker sem se pozanimal za
TMM 5024-3 42000 (50 A- stalnega toka; 60A do 5s) Ta regler je zelo tezek (54g; 40g brez kablov) in podpira 24 celic tko da za avte ni naj bolj primeren Ima pa pet stopensko nastavljivo bremzo, kar bi bilo lahko zadovoljivo

Pozabil pa sem vprasat za BK Electronics Warrior CAR regler tko da ne vem niti za okvirno ceno je pa ta regler veliko lazji (18g)in obstajajo verzije z 40 A , 70A 99A (sledi link za vec informacij)
http://www.rumrunnerhobbies.com/controllers1.htm

Bom jutr poklical v MT in se pozanimal se za BK reglerje in BASIC motorje



LP Tadej

[mihah]

Ko boš omenil BK reglerje in Basic motorje te bodo samo debelo gledali. Do maja naslednje leto težko verjamem, da se bo našel štacunar, ki bi to imel.

Za reglerje je pa tako:

Regulatorji krmilijo 3 faze. To pomeni, da če hočeš imet enako zmogljivega kot ekvivalentni krtačni boš rabil 3 x toliko fetov. Naj te teža nikakor ne moti. Tudi mene je na začetku in tudi velikost, a se navadiš. Raje težji regulator, kot pa manjši in lažji, kajti BK motorji imajo dosti nižje notranje upornosti in potegnejo veliko toka v štartu.

Glede 5 stopenjske bremze...

poglej si malo navodila na

http://www.mgm-compro.cz/en/

(download/manuals)

Bremza je v vseh primerih on/off , nastavljaš le "trdoto". Torej če bi bilo bila pogojno uporabna samo lahka "light".

5024 res ni pravi tip če že kakšen 4012, 6012, 8012 z BEC.

Warrior 70 A tehta sam regler brez žic definitivno več kot 28g, žice in hladilnik pa dajo okoli 50 do 60 g. 99A je še nekaj težja. 40 A pa je PICO, drugačen (manjši) reglerj, zasnovan za majhne modele (ja tudi za 1/18 ipd). Samo za 1/10 je pa kriza. Bi šel v lahkega 1/12, samo s pazljivo izbiro motorizacije.

Ker maš lažji motor lahko maš mirne duše težji regler Ne res, pri reglerju ni za šparat, kupiš najboljšega, ki si ga lahko privoščiš. Kurjenje reglerjev je drag špas...

Res škoda, da gospod Dvorsky (MGM) še ni dal ven reglerja s CAR sotwareom. Nekaj se je govorilo že spomladi...

[rcman]

To sem razumel da je bremza samo on-off ter da ji lahko stimas samo intenziteto Mal pa me je presenetilo da bo samo naj bolj svoh nastavitev uredu za avto Sam sem upal da bo najmocnejsa nastavitev dobra za na asvalt z zelo dobrim oprijemom, ce ni tako pol bo zelo tezko vozet ce bo slab oprijem .

Miha mi lahko ti poves kje naj potem dobim kaksen regler. A je se kasna druga moznost poleg narocila preko interneta. Grem raje v Avstrijo vsaj za davk in carino prisparam pa se postnino.

Lp vsem

p.s: doma imam tudi starega hrosca, ki se ga bom lotil ce bo 1:10 uspel pri tem se bom pa lotil verjetno vecje predelave. Naredil bom novo ALU plosco, krajso tako da bo gor pasala 1:10 karoserija

Pozdrav!

Mene pa zanima ce obstaja kaksen model BKja od MEGE z lastnostmi krtacnika z 12imi ali 10imi ovoji?

Sem ze gledal karakteristike BKjev pa ne vem cist tocno po cem bi jih lahko primerjal z krtacniki. Ce prov razumem so pomembni obrati na volt in pa maximalni tok. Imam prav? Bi potem MEGA ACn 22/20/1 ali pa MEGA ACn 22/20/2 bila motorja ki bi delala cudeze z 1:10 modeli?

Lepo pozdrav.

[mihah]

Tadej, najmočnejša bremza bi po vsej verjetosti povzročila permanentno okvaro prenosa.

Kakršnakoli vožnja v tujino ti bo dala samo stroške. Ker je roba made in EU ti lepo tam kje kupiš odštejejo davek, tu v Sloveniji ga sicer nekaj več plačaš ne plačaš pa carine (mora bit uradno napisano poreklo).

Poglej si še tole http://modelarji.com/phpbb/viewtopic.php?t=920

Zatorej kar lepo email na BK pa počakat da poštar prinese

Čudeže? No ja.

Mega ima v svoji ponudbi na uradni strani http://www.megamotor.cz "MEGA ACn Car" motor. Razen slikc na strani (podatkov ni) nisem nikjer druge zasledil da bi kaki uporabniki kaj pisali o vtisih.






22/20/2 se že vrti prepočasi za 6 celic (recimo tu bi bilo bolje bi bilo uporabiti RC1200 2/3 SC akuje).

Če že hočeš se it "malo bolj resno" je že bolje it v nakup Basic 4200/5300 in Warrior 70/99 A CAR regler. Basic 4200 za bolj "mild", 5300 za bolj "hot".

Daš malo več, samo zadeva je dobro preizkušena in deluje kot se spodobi.

Je pa še ena alternativa zelo poceni. http://www.flyware.com Motor za 50 Euro in reglerji za okoli 80 Euro....

[alesz]

Zivjo!

Miha res ne vem kaj imas proti Megam. Tole je moje novo orožje, manjka mi le še pošten regulator, pa sem pripravljen na izziv.




L.P
Ales

[mihah]

Aleš, kje sem napisal, da imam kaj proti MEGA motorjem? Na mojem testu sigurno ne, saj je zame motor absolutno zmagovalec.

Ne jemat za sveto to kar pišem, pač moje mnenje. Prove me wrong pa bom drugače potem govoril Res manjka dialoga in pisat samogovore in pri tem bit vsem všeč pač ni mogoče. Dejmo fantje debatirat tako kot se spodobi.

In Aleš, velike pohvale! Je to 15/25/1 s 5000 obrati na volt? Če je, je to res fleten motor in verjamem, da bo v Pro 3 precej pestro. Sploh pa za to ceno!

Kakšno "orožje" boš izbral za regulator?

Dejmo se pogovarjat kot modelarji.

Še kdo s kakšnim projektom?

Kako boš pa rešil z vmesnikom na 540 pritrditev?

Brushless systems
The rising popularity of brushless motor (BL) systems has evolved the racing scene in Singapore. The use of BL systems in races was initially started by Hobbylink more than a year ago with its themed “Ultimate Touring Car Challenge”. During then, the folks at Hobbylink used BL ESC by Schulze (Germany) in combination with LMT BL motors (Lehner). Now, we are still using it to great effect!

The BL system used by Sam/Bryan respectively:
ESC: Schulze Universal 12.46e / Schulze Future 58CE
Motor: LMT Basic-4200 (Lehner)

[mihah]

Čas leti mimo nas, proizvajalci pa delajo nadure



News on the Hacker/Jeti ESC:

the tech datas (might be changed till it comes on the market !!)
100 A in the sport version
limiter could be set to 40 60 80 and Unlimited Amps
very low int. resistance (0.0012 that is low for a 3P Controller)
everything is splashwater proofed maybe totally waterproofed (has to be tested out !!)
setting is very easy, as it was everytime.
the housing is complete aluminium, the esc is then set in from the back, then filled with silicon (or similar material)
the other settings:
4, 8 , 19 Khz, timing from 0-30 ° (in 4 steps)
brake or brake AND reverse selectable
cells: from 5-10 !!
The cogging depends on the setting of the timing, in my optimum setting, it is possible to flip the neutral trim a little (only 3-4 steps on my MPX 707) and the car acclerates at very low speed, without any cogging !!!
The cogging is gone, a really great benefit !! (but the final testings will be held this morning, i will put it in my Car, and see where the difference between this ESC and the Warrior 7018 is !!
(first bench test impression: the start up with the Hacker is smoother than on some of my Kontronik or Schulze esc´s esp. better than the Warrior wich IS weak in this point !!)
OK, i will keep you informed, but the date of availablity is not cleared up, in Germany it might be around the next 2-3 Months ready for x-mas, in the US, not imaginable, maybe the same time, maybe 2 months later, depends greatly on the volume they produce for both markets !!
(but as i hear a date, i will post it here)

I have a closer view of this esc, enjoy it !!

OK, here is a Spy pic of the new (not yet released Jeti/Hacker Car Master Sport (a Comp. Version will be available too))

The Paper dummy stands for the real size of the "old" Hacker Sport, the dots or "minus" claim the size of the new Schulze esc the U Force 50/75 (also not yet released), so this might be a good comparison.

[mihah]

Če sem že tle pa še tole:

MGM Car:

Availability:
I got 2 without problem in march 2003
TMM vs Schulze :
I tried only MGM TMM car version
Usage:
Solar powered RC car
Performances
very good, forward-brake-reverse
permanent programming
used with a brushless LRK AXI 2808
at very low current (2A)
Efficiency(ESC+Motor) estimated @ 90%
at this load

so.. finally first run today:

http://www.kraeuterbutter.at/Videos2/Lo ... _musik.avi

http://www.kraeuterbutter.at/Videos2/We ... rf2003.avi


so:
whats to say about it ?
the motor was lying around - its for my emaxx... but iam missing a emaxx-steering-servo, so it findit a place in the XXX-4

the motor spins only around 20.000rpm on 6cells in the XXX-4
nevertheless.. it performace nice i would say..

for controller: i was afraid that the controller could be damaged because its only a 40A-controller..

but.. it seems to work.. gets only 38°C warm... (thats about human body-temerature.. can´t say how much °F that is..)

was first batt with that car...
first batt with that motor
first batt with a pistol-grip-rc for me.. and well.. it works very very fine !
also the programming..

the controller has very very hard brakes.. so i limited it through transmitter to 55% works great now..

also cool: you can limit the steering in relation to the gas-throttle -possition..
so: on tight turns much steering..
driving fast only reduced steering..

there is a scene on the video, where iam driving snail-lines at full-throttle..
with my old rc that was very difficult..

i love the multiplex profi 403 sofar..

hope to get back my damaged lehner basic4200 soon so i can mount that into the car... because the hacker c40-10L is to long so i can´t mount the body without making a hole in it
