    yeah, now i need to know how to clean em up, nothing really works, two red gears do normal sound but white second one ( this smaller ) is doing all of bad sound, without it, all gears work well...

    Ok, im kinda idiot, but i have to wait for new buggy motors, i had to repair mine cause i was driving in the sand, but i think if i use pressured air, oil, and clear them wih spiritus, they will be ok, but i had to glue one a bit, i had destroyed all of mounts when dissambleing top of motor to clear up gears... i was driving in the sand and now gears are making voices like crazy...

    Yeah i know about crawlwer tires, i watn to buy trac tire, zolle is a bit to far for now, tomorrow going back Poland, but, in holidays i also be in germany for few weeks, and i have about 200 km to zwolle, so maybe we'll race :) My motorcycle tires are from 8051 :)

    I dont know about c rating of them, i bought four of soshine 3,2 v 700 mah batteries 14500 ( aa size ). About measuring speed, my grandfather have an, i dont know how to name it but its a little thingy that tells u about how much distance u had driven from restart, max speed, and real time speed shown ( just like in ccar). For now i need to wait till i buy trac tire, now i have only tires from crawler ( my biggest ) and two from motorcycle, same as u used in your, ill do a post here and vid in yt but be patient, its going out in about 1 month, first need to do own project, wait for new batteries 2 weeks, nwait for tire and i need to go back from germany, btw in which city u live? i got about 60 km to netherlands :)

    I know, now i had to return my li ion charger, but luckly today its 14th day and i had informed seller about return, ill buy li ion + lifepo4 charger. Yeah i know that li ion maybe will be better in PF batbox, i want to try to do what philo show to not have to use all 6 batteries on his website, no with fakes, i want to cut out one side of both aa battery boxes and this grey part cut in down side and try to fit in it two pre cut battery boxes if u know what i mean, i want to use in one 2 li ions, generating 8.4 v for ir reciever, and in other 3 li ions generating 12 v for motors, i got problem with one thing but i think everyone know what it is - money... I need to wait a week till i get money, just bought lifepos and charger, and i had to buy aaa bat box, and one li ion aaa battery cause i had 4 and need 5, now i need to wait 2 weeks till iget lifepos and ill try them with rc unit, i had to say that in germany where now i am on a little holiday, in Aldi shop there are super life alkaines, super cheap and super powerfull! i tested them with fresh new energizers and only lithium ones were better, but one of those super life alkaines cost just 0.25 euro so im gonna buy about 40 of them, just 10 euro, btw i used them just for a test - i saw on whitespahes channel that his white superwonic was driving at about 12-13 and max 15 kmh, my just about 10 kmh and lower with 2 li ions fully charged, now i used alkaine ones and its max was 12,7 but not on flat , i need to test it on asphalt.

    I decided to buy 3 lifepo 700 mah 3,3 volt bateries, at fully cahrged they got 3,6 volt so 10.8 volt total, hope they will be powerfull.

    Hmm, i think that on not long runs, 3 li ions generating 12v will be good to beat high speeds, i want to beat 30 km/h with steering :) i tried it and it dont fry whole rc unit even at 1 minute drive. still thinking about Ram - rechargable alkaines, but i dont think that they are as good as normal alkaines... Im kinda mad cause i invested much in li ions - 25 euro for lcd charger, and15 euro for 3 aa 800 mah ones, and 15 euro for 4 600 mah aaa ones and 2 li ions are worsee than 6 new alkaine ones.
  8. rkkm
    Today ill be testing how much better are 6 new alkaines than 2 fully charged li ions, i also still think about using 2 800 mah li ions and 2 800 mah nimhs, what do ya think?
  9. rkkm
    i had found Ram batteries too ( alkaine rechargable ones ) are they good? Theyre specifics are: 1,5v 3000 mAh no heavy metals, zm-mn type, heres link to wikipedia : https://en.wikipedia.org/wiki/Rechargeable_alkaline_battery And i found info that li ions got much less mAh than alkaine ones, and kilo watt hour are less ( 3.90 in alkaine, 2.80 in li ion) do kilo watt hour got much to tell for peformance? are they important? Im really confused why my 3.7 v 800 mah li ions are worse that 6 alkaine ones...
  10. rkkm
    im kinda confused. Im in germany and i was using still 2 3,7 volt batteries li ion and 3 fake aluminuim batteries, now i have used 6 new super life aklaine batteries and they had better performance and supersonic is faster a lot, but from maths its weird, 2 li ion fully charged batrteries got 1600 mah and generate 8,4 volt and weight 42 grams, 6 alkain ones generate 9 volts and weight 150 g. its wery weird for me - alkaine generate just a bit more voltage cause 0,6 v and weight 4 times more than li ions... And im thinking what do u think about mixing bateries,. i tried 1 new alkaine and 2 li ions for few seconds, it wont blow or anything and supersonic was faster, im thinking about 2 li ions and 2 nimh, but what do u know aboout mixing bateries>? and can someone explain me why the hell alkaines are soo better? from maths they could be worse, weight 110 gram more and generate just 0,6 v more, i hate non rechargables but if alkaines are best, is there way to recharge them? or are there rechargable batteries alkaines, or nimh 1,5 v? im really confused now, i tried today 1 fully charged li ion at 4,2 v and two 3,6 v low charged and still, super sonic is super fast but i cant drasticly change rotation cause motors stop work for few moments, i had to spot supersonic then change rotation direction... one last thing, anyone know if they are alkaines with better voltage or other batteries with dofferent voltage than 1,2 nimh, 1,5 alkaine, 3,6 and 3,7 li ions?

    firstly hey marx, im have builded almost identical vehicle as your on channel with steering with speed record 29 kmh, just other rear wheel. For rc unit i use 2 li ion batteries ( charged 8,4v discharged 7,4 v) so for now nothing can happen, i just want to put third battery and reduce voltage cause charged it would be 12v and i want to reduce it to 10,4 volt, no problem with rc unit - i got 2 of them one bought for testing, i want to put third battery and reduce its voltage with those diodes till motors will stop stopping when reversing rotation direction. so solution with diodes is dangerous or not? im confused, maybe theres an other way to reduce voltage of those bateries?
  12. rkkm
    but these diodes wont do any damage if i put em into rc unit and drive it for a few minutes connedted to buggy motor?
  13. rkkm
    dont really understand what do u mean about diode heat, 3 batteries will generate in diodes 3 ampere and 2,4 watt, can i reduce it? i want to have 3 batteries fully charged and i want it to be save, safier will be 0,6 or 0,8 v diodes as u said? and short races mean? When i go outside im driving 10-20 minutes with few rests for model, would that be dangerous?
  14. rkkm
    Yea i need those fake batteries which reduce voltage, i got 3 14500 3.7 volt aa bateries, i bought supersonic racer , and i was testing, with all 3 fully charged and 3 fake aluminium bateries, motors works well, but not buggy motor, it gots problem with that voltage when we reverse direction of rotation, when i turn on buggy motor it is ok, not smellining like fired, not act like crazy, but when i change reverse direction it stops... Same with supersonic, i put 3 batteries not fully charged ( one 3,8v and two 3,5 v) and it goes welll till i reverse direction of rotation, it stops buggy motors and servo, and does sound like brrrrrrr grrrr or anything like error sound, i also tested 3 bateries fully charged with ir reciever v1 and it is smelling kinda like from china but also ir controller smells same , but i got crawler 4x4 too and ir reciever v2 and its controller doesent smell anything, im using in rc unit 2 fully charged batteries so 8,4 volt, but i want to use those reducing voltage. How much one fake battery with diode will reduce voltage? if i put 3 of fake diode batteries and 3 fully charged generating 12.6v how much fakes will reduce? can u do some photos of how to make those fake batteries? i dont really know how to make em from those photos,just if u could do photos of materials needed and little guide please :)
  15. rkkm
    Where do you bought these fake batteries with diodes?
  16. rkkm
    Thanks for help :) i wont buy lipo, i have bought three 10440 ( aaa size ) 3,6v batteries, ill put only three of them into batbox and three aluminium things in form of aaa baterie ( i found this way on philohome ).

    What do you think about li-ion 6800 mAh 4,2 volt rechargable AA bateries? I found em on polish Allegro and aliexpress: https://pl.aliexpress.com/item/4-pcs-lot-Original-18650-Li-ion-2600-mAh-3-7V-Lithium-Battery-18650-Rechargeable/32802038516.html?spm=2114.010208.8.17.nIx74g what do you think about em?

    Im new to this forum so hi everyone ;) i have fun with PF from few months, and i want to buy a li-po and customize it to lego, i got two of real power hungry buggy motors, and i want to feed em' as much as i can :D I only need to know which voltage is maximum for motors, and for reciever, i have maken a research across internet, and ive heard that motors can handle max 16volts , and reciever just 9 volts, but ive heard too that motors can handle max 12 volts and that reciever too, on many forums i have read different numbers, so i have to ask here :) i have found light and small 14,8 volt li po 850 mah, in good price and i like it, but i dont want to burn my buggy motors and rest of PF, im wondering too about rc unit voltage, if it have 6 aa 1,5v bateries fully charged, it could generate 9v as normal pf battery box but when i compared them, rc unit is way better, and buggy motors are way faster, i hope that someone can help me :)
