It's probably not this exact motor on the car as the original transistors are those 2SC3420 so also same 5A, could be the RS380PH or other with lower stall AMPS.
OK so ballpark, I am looking at a ratio 20 (stall motor)/5 (transistor) A? I found this transistor to replace that 2SC3420, The 2SD826, the numbers are quite close to the original, should be a correct fit .
If we consider the Mabuchi RS380SH , The nominal voltage is 6V but a 24A stall current?? Then it would fry the vast majority of those transistors..?! Not sure I got this right..
Hi folks,
I need to replace a burnt 2SC3420 transistor from a 1/10 Eztec RC Toy car that runs on a 9.6V/1000mah nicd/nimh battery pack, brushed 380 motor for some kind of reason the prices of those specific transistors are insane ( for what it is) so looking for a replacement part I came across...
Hi folks,
I'm still looking how to boost some few RC cars using a lipo 3S instead of the standard 9.6V nicd/nimh packs and my last attempt on different cars resulted on a fried NPN transistor on the circuit board of one of the cars. Then I decided to do a little more research and it seems that...
My experience with quite a few RC Toys has showed me that high end quality Rc such as branded RadioShack, Tyco, and Nikko use their very own TX and no matter the 27 or 49mhz range and even more each car from those brands use in general its very own TX! Another experience today done on a tyco Rc...
the funny thing is that every time I have experienced a problem using the wrong TX still with either the 27.145mhz or 49.860mhz it would always either reverse steering and or forward and reverse but never with more or less power more like nothing at all or normal power. This time is the one and...
Hi folks,
We have an RC club at school and we are trying to undertsand the problem we have on a Radioshack rc Jeep http://support.radioshack.com/productinfo/DocumentResults.asp?sku_id=60-4300&Name=RadioShack%20RC%20Toys&Reuse=N
and as we don't have the correct transmitter so we tried...
Looking backtothis circuit board I toticed that the particular transistor that smelled burn is soldered to a 5W rectangular ceramic resistor, would that be possible that the resistor burnt and not the transistor and why one of the 4 transistors is soldered to a resistor?? I know I should post...
Ok then it might be another motor as the original transistors lived well for close to 10 years using the standard 9.6V pack. I wanted to order those new transistors and it seems like a plag...Shipping prices are insane!!! Will need to see where I can can some locally.
Thanks, makes sense. I found those old transistors here and there but I think I will go with those 10 amps. Also do you know what amps I should look at when it comes to the 380 brushed motor? Is it the stall amps draw or maximum efficiency amps for example the Mabuchi RS 380 PH that would make...
Ok then as this for a lipo battery that would generate a lot of amps not sure how this transistor would handle the situation.. Ihave searcged for a while and simply I think that there are no such through pins transistors to have all the right characteristics, I will probbably try to just replace...
