I have the EVSD-5U-PRO valve in my turbine jet and it had a Futaba receiver and radio system. The valve worked perfectly last summer with Futabu. It was changed to a Spektrum system since that is what I use. Since then, the gear and doors work perfectly but the brake function does not. The brakes keeps cycling no matter what is changed and we have reviewed the manual and settings. I have the AR20310T DSMX 20-Channel PowerSafe receiver with 6.6V LiFe receiver batteries.

Is there some special setting with a Spektrum radio system that is needed to make the brake valve work properly?

Thanks.

I've heard of this before, but I think I remember hearing problems occurred when switching to 2.4 from 72 MgHZ.

If my memory serves me correctly, I think the problem turned out to be uncurable, but, I can't even remember this post as I write it! Ha!

HSR has a new valve that replaces the EVSD. I have 4 of those valves working liking a champ after years of abuse. I love them in air models.

Try Increasing the percentage of travel to at least 125% if the Futaba was at 100%
