HY 120A-1S 晤落散熱?

發覺裝好盁 120A-1S 落 CRC GEN XL & PROTOFORM AMR-12殼, 如果加ESC散熱會頂住個殼,
(準備用1S LIPO + 4.5T)

見過有的外國12仔比賽都無用散熱 (不過係TEKIN, NOSRAM)

有無師兄試好盁 120A-1S晤落散熱有無問題?

先 check check full load ( 1s lipo + 4.5 T )幾多 amp 先？

I use 3.5t and ESC is very hot...  70 degree+.  Just tape the fan onto the ESC will help.  And will be able to clear the AMR body.

My problem is I cannot install the heatsink at all.
Thx

HY-120A-1S比較大,打橫會頂住side link.而家謂有打直放散熱靠出 (右邊). 但靠出個AMR12殼比較低身,剩6mm到,原裝散熱兩邊有7mm,小小頂.風扇有10mm厚一定放晤落....

I place the ESC on the other side and turn 90degree on my r5.  Ya, I think the side link is longer on the crc compare to the R5.....

I have found some 5mm thick heatsink. Order it through web and wait for it to arrive and see if it fits. But certainly cannot mount a fan

Maybe you can use the heat sink and mount the fan standing up?  Seen it done before.  not as good as mount it on top but it works.  

I have received the 5mm heatsink (Left), original is on right
Also received some very thin 3M heatsink stickers

Also mount (by double sided tape) the fan in front. Blowing air backwards
I wonder if I need to buy a high rpm one, because it seems like the air flow is not very strong when powered by 1S Lipo

The only problem I still have is the small original spur gear (76T). Since this is so small, I need to use a pretty large pinion gear (34T minimum) otherwise motor would hit the rear shaft. I wonder if 76T spur is design for high T motors?
Right now the rollout is close to 67mm which I guess (I am newbie, just learn from forum) is too high for 4.5T motor. Plan to change it to 96T sometime, but I need to wait for it to arrive.

Hello, for your reference, mine using 24/96 (64 pitch) with 4.0T.
Are you waiting for CRC spur? Actually, you can try other brand instead of waiting for CRC.

Very nice ten two son^_^

Thanks and I have ordered Kawada and also CRC (Kimbrough) 96T. Cause I live in Beijing and most things need to be bought through mail. So I need to  be a little patient.

BTW, CRC now has two versions of spur gear. Originally is made by Kimbrough with 12 1/8 balls. Now they have a version which has 16 3/32 balls. Wonder if anyone has tried?

回復 16# eyhpoon

yes, I had use the 16 ball spur before.  Not really necessary as the diff will not slip much anyway...  BTW:  The spur came with the kit is for stock racing only, Mod change it to 87-95t la.
