Thankyou. I just wish decent lipos weren't so expensive, and i've only just bought the 18C specifically for this truck! I must do a comparison of both batteries whilst driving in the same place and see if there's a difference. Come to think of it, i usually use the 18C but today it went further without cutting out and today i was using the 20C. My 1/8th buggy with its bigger 550 motor runs perfectly on the 20C though.

OK thanks. How would i be able to run a direct feed from the battery for the fan that's only 6 volts? I have two 3s lipo batteries, one's a 20C and the other an 18C, do you think that would be enough to attach everything to the reciever?

I see. That makes sense, it was the cheapest ESC/motor combo i could find as i don't have the biggest budget in the world. the only problem is that i only have a three channel reciever (on the AM radio at least) so i may need to invest in a y-lead so that i can have the ESC, steering servo, failsafe (there isn't a built-in one) and motor cooling fan all connected. Either that, or i could get another 2.4ghz 4 channel radio but i don't want to spend too much more money.

Thanks for the reply, i forgot to mention that i tested the BEC of the esc in both vehicles with a volt meter and they're almost identical (just over 5 volts), so i don't think that's the problem. I just don't understand why the 2.4ghz radio works perfectly in one model and not in the other.

Yeah, i've opened up both the AM and the 2.4ghz and can't find anything obvious. the thing is, the 2.4ghz works fine in the buggy that it came with, but just as badly as the the AM when it's in the truck. i've made sure i calibrated the truck's new esc to work with the 2.4ghz reciever and everything. do the brands of the esc and radio have to match? i'm wondering if it would work with an Etronix (same brand as esc/motor) transmitter/reciever.

Hi there, I'm new to these forums but have been into RC vehicles for about four years, and am hoping someone has the solution to my problem. Apologies in advance for the long post. I recently decided to rebuild an old 1/10th truck I have and convert it to brushless, as i also have a 1/8th brushless buggy and know how good brushless can be. I bought a 3s lipo and an Etronix ESC/motor combo for it. Since the rebuild and installation of new parts the truck has developed a massive range problem. I used to be able to drive it over 100 metres away but now it's about 35m when there's no interference, 15m near my house with all the powerlines around. i have tried replacing the AM radio with the 2.4ghz one from my buggy but this hasn't helped a whole lot. I sent the ESC/motor combo back to modelsport for testing but they didn't find anything wrong. i've tried braiding the motor wires, moving the reciever further away from the ESC, every solution i've found on the internet i've tried but with no success. the more i drive it the more convinced i am it must be the ESC because i know the radio isn't the problem. the ESC and motor also get MUCH hotter than i would expect and it runs down both lipo batteries i've used really fast, much faster than my buggy... Is there something else i can try or is there something wrong with the ESC? Any advice would be very much appreciated.
