Ko propo or sanwa servo

[Col C]

Hi all, I have got a savox 1257tg in my bmax4 at the mo but after reading about them being a bit power hungry, I am looking at something that might be a bit less of a load on my electrics.

I have been looking at the ko propo RSx2 response servo I've found at Wheelspin for £108. Or the Sanwa SRG-BZX Type R servo from smd direct for 139. I was thinking of the Sanwa as I have an exzes z so could use it on the Sanwa digital servo setting. The other thing is I have only found 1 place selling the spare gear kits for the ko.

When I raced years ago it was all ko, but opinions seem a bit more varied now.

Open to other suggestions too please.

Thanks in advance.
