Sorry for the confusion Lads.

The SLU will reduce its speed by 50% when it reaches 50% of its hit capacity. At this time, it will not reduce its speed to 25%.

OK, here is the good news. Mr. SLU (the manufacturer in Beijing) is working on a replacment chip that will allow the SLU to reduce power to 25% when it reaches 25% of its hit capacity. We want to test it first before it is available to consumers. The SLU is intended as an upgrade for stock HL tanks and I don't want the 25% power reduction to turn tanks into static pillboxes. So testing is needed. We are looking at a retail price for the chip upgrade of under $20.

I am very happy to hear people like the product and I appreciate the feedback. The SLU is not perfect, but I believe it meets a current need, at least until the next better system comes along LOL.
