I have just bought a second hand Axial Wraith, set up as a crawler, with a lipo battery (my first car with a lipo) when running the car it goes forwards and steers perfectly, but reverse is hit and miss. The led on the esc blinks when reverse is selected but it only goes backwards one in ten try's? Before I get a new esc and possibly change to sensored brushless is there anything else I should try first? It is currently brushed wit a Fushion esc.
Im not sure how good the battery is either, the charger it came with seems to charge it ok but it doesn't have the punch I was expecting from a lipo, like I said I'm not used to them though.
Any advise would be greatly appreciated,
thanks Jon.
