Protek makes a dedicated case that you can reuse if you upgrade to a different transmitter by switching the foams. You can get a soft case from Sanwa as well. The MT-44 batteries are different than all the other batteries that are meant for the Sanwa transmitters, so the battery won't fit. The rx481/2 is the best 1/10 receivers you can get. The rx471/2 is the best for 1/8 scale.
