標題: New gear on old stuff !
Finally make up my mind to buy new gear for old car ( delay for 6 months ) !![attach]292059[/attach]

Is it able to withstand this kind of power!!

作者: gimsink 時間: 2009-8-16 23:02
don't know, but I believe RC10T, even 18yrs old but the gearbox quality should be still good, I think no problem. If it burns the stealth transmission, then I have good excuse to buy new car la !!

呢架車一定頂到好盈，放心

I use 好盈 4300kV to play my RC10T at TKO for almost a year. No problem.

C Hing 無問題唔使驚,我都係RC 10 (91年)都用好盈 4300kV .

BL ESC/Motor setup and run OK. I was using old KO FET servo in this car, but when I plug-in to the new EX56UR it didn't response (but it work with my old EX-5 OK wor), so I try to use a new MGTower servo, it works OK with the new EX5UR. But when I plug the servo saver into the MG servo, I found that the servo gear do not match with the servo saver.....
Is the new type servo gear different from old type servo ?
Or is KO servo gear different from others ??

If I remember correctly, the servo gear of (KO, Sanwa) are different from (Futaba, JR, MGTower )

Exchange the old KOFET servo black and red wire position and plug into new EX5UR receiver. Ha, it work wor !! Can us la. The old KOFET servo was not cheap, HK$295...18yrs ago ah !!

All ching help. I had finally setup the BL (Hobbywing 35A/9T) and find that if I reverse run the car and forward run again, the car will have no response, then I need to pull the forwrad trigger a few times to get the car run forward again. Is it because of sensorless motor it cannot check the rotor position and sio cannot start ??

作者: ryancmlam 時間: 2009-8-29 22:05
My hobbywing 35A/9T system I doesn't have such kind of response. Don't know whehter it was due to the setting of ch2. You can try to
1. Switch ch2 from "normal" to "reverse" (or vice versa)
2. Swap the connections of any 2 out of 3 wires of the ESC/motor set

Hope it is of help

1/. Ch2 normal + reverse means what ? The EX5UR is factory presetted REV.
2/. If swap any cable to BL motor, the run direction will be reverse.....it looks like cannot solve my problem....

I mean you should switch the ch2 of your EX5UR from REV to NOR and then swap any 2 wires of the BL motor. As such, both "reverse" at transimitter and ESC would still let the car to go forward. I suspect the scenario you described was due to you used the "reverse" mode of your ESC as forward and hence the so call "no response" might be a protection. It is my guess only, don't know whether it is true.

I had the same problem with my hobbywing 60A, can't be solved I think

I test run the car on sunday with the BL35A/9T on original RC10T gear ratio, the speed is very fast. But maybe the tires too old and aging and become harder surface so the grip-to-road surface is low (you know la, 18yrs old car and sit in warehouse for 15yrs...) and drift a lot when turning corner. Do you have any suggestion on new tires ??
The problem I said above is a big problem, sometimes the motor does not response, I don't know how to solve, if bingobingo ching has the same problem, that means it's not only my BL problem....so what shold we do next ??

作者: ryancmlam 時間: 2009-9-7 18:57
gimsink hing,

I use HPI 4411 read tire, it is very good.

Thanks advise, I will buy and try.
One more thing I didn't mentioned, beside the BL35A/9T sometimes no response on forward, I also find that when I accelerate the car from stop, it's always not smooth, sounds vee ... vee ... vee ... veeeeeeeee ( i.e. car run slow .. slow ... slow.. accelerate very fast ).
Sorry I don't know writing chinese but hope you understand what I mean.
Is it a normal problem for sensorless system ??

作者: ryancmlam 時間: 2009-9-8 20:16
I just know that some poor quality Hobbywing BL35A system will have such kind of response. i.e. when the throttle is bring pushed slightly, the motor will vibrate a lot and sound....clik...clik.... and then run very fast.
