Hello everyone, I am looking for some sort of cheap multi function unit to replace two mechanical speed controls on my vinatge Kyosho Blizzard. Not really a tank per say like most of you run but it does have tracks and twin motors. After doing some prior research, the recommendation was a Sabertooth. I'd really like to find something cheaper and thats where I see alot of people use the Heng Long RX-18. I have really no knowledge of what will or won't work so I would like some recommendations. If I do choose the Heng Long, can I still use my Futaba radio or will I have to purchase the Heng Long radio. Thanks!
