I have play both 4pls and MT4S, at the end I have chosen to keep the MT4S, below is the comparison between two:
1) build quality: Futaba feels like a cheap mainland toy, weak plastic, screen easy to scratch, MT4S feel more solid and comes with screen protector, a ring for neck strap
2) MT4S has higher signal resolution, I can notice that my servo is more stable with sanwa, smoother overall control
3) Futaba 4pls comes with 2 receiver for 1550, but Sanwa MT4S only comes with one 472 receiver and 2 rubbish servo for 1650
4) Futaba receiver only cost 350HKD but Sanwa 471 or 472 is around 600HKD
If money is not a concern, please go for Sanwa, I have better overall experience with Sanwa, hope is helpful for new player |
