  1. hi all I have read that in order to convert from kv to rpm the math is 1000kv motor with a 2s (7.4v) battery will give 7400rpm. it the math the same for nimh? so that a 7.2v nimh will provide 7200rpm (for 1000kv)? thanks
  2. hi all; is there a timeline where a car is considered vintage? what is the criteria? would a car that came out in the early 2000 considered vintage? is it only looks that determine? (is bbx vintage for example?) many companies, like schumacher, have a timeline of 4wd cars dating to the 80s i think and continuing to this day. so where is the cutoff vintage/not vintage date? your thoughts are welcomed...
  3. 86, a new tamiya fox made its way form the US to me with a friend... a thundershot came a year or 2 later from the UK... almost 40 years later i found myself here
  4. Hi guys; is there a shop that sells tamiya PS spray cans in NYC? the tamiya usa site store locator is useless.... thanks!
  5. i am not a lipo guy. it simply is not for me. I want to buy a battery and forget about its maitanance. is there anything out there that will provide more juice then the nimh but will not require any sort of maitanance (like nimh) ? 10x
  6. @scoobybooster i messaged you
  7. hi all I have noticed something I was wondering about. in the optima mid rere there is an instruction that I assume is not mandatory that states to use silicon oil inside the differential. I am not sure if this is instead of grease or together with grease. it has 2 references in the manual (see pics below), can someone comment about this? why is it even there? i have seen 2 builds online, one that uses just grease and one that uses grease and in the voice over states that he used solicon oil. i was wondering if anyone can comment on this. thanks
  8. @Anthroxoidi believe your links do not work...
  9. thanks everyone fo the comments. they were so cheap and tiny i couldnt resist and bought a few. they will be used exclusively for driver figures. thanks again
  10. Hi all Just bumped into these (see attached) with a low price and nice tiny cans. They were tagged as modeling colors. Anyone knows this brand and can comment? I intend to use them for the driver figure in an rc car. Thanks
  11. If you are patient, Tamiya will re re. No worries 😁 Even kyosho gets it It's a shame that other brands rere less often.
  12. BTW, you can hopup the tt02b very easaly and cheaply from aliexpress. full bearings and all the aluminum you want and a fraction of the price of the official hopups.
  13. i got lucky and a friend from NYC brought me 2 cans. TBH i dont undersatnd why getting this on the plane in a suitcase is ok for via mail its not ok. i need to be really stingy using them. from all you guys experience, would a single white can be enough for a single car? for instance the optima mid? i need to know how to ration my usage 10x in advance.
  14. this is funny. I have never seen a person nick-named "JUNK MONKEY" caliming someone else is a scammer (no offense @junkmunki ) FYI, there is a scamming forum in TC. you can find it here: https://www.tamiyaclub.com/forum/index.php?/forum/26-suspicious-traders/
  15. just a small note. i have a new JX 4409MG and Injora injs014 low profile budget servos which I put to a speed test. both pretty similar speed wise but the jx is super jittery and seems super unstable as oposed to the injora which is super smooth and does exactly what is expected... just my small test and experience... and so, no JX for me in the future.
