I bought myself a new Spektrum DX3R for Christmas. I have 3 cars, a team ae RC8Be, a Savage Flux, and a Slash VXL converted from a 1-year-old rustler. I put the SR3100 rx (the one it came with) in the RC8Be, and I wanted to put a SR3000 (The older DSM rx) in the other two. However, the lhs did not have any, and said the losi DSM rx was the same thing, and they had two of them, so I bought them instead.

I just got back from running my Slash for the first time this year, and it would lose signal every once and a while at radom places. It got pretty annoying, and since I plan to race this truck over the summer, I would like to figure out why this is happening. The transmitter said 5.4 volts, and the car had a freshly charged 2s lipo pack. and I'm not really happy about it. The frame rate is at 16.5 ms.

In order to get the antenna wire to the tube, I had to ream a small hole on the side of the rx box and run it up and into the tube. Since Iwould like to run this in snow, so I put sme hot glue over the hole to "seal" it.

So what do you think is wrong? Is it my setup? The losi rx?

Thanks for reading, please help!

It may be that the servo is causing a brown out which is when the power to the receiver drops momentarily. Try using the $5 Spektrum rx capacitor, that helped my brown outs.

Interesting. You're right, it does feel like brown outs. I've never heard of a spektrum rx capaciter.Where would I get one and what does it do?

Thanks for the quick reply

They are a capacitor providing power to the reciever when threre is a pwer drain from things like a high power servo. Simple to use, they simply plug into an open slot on the receiver..

While 2.4ghz is the cats azz, it's not without faults. I have raced in areas that even 2.4 can have glitching issues but it's rare. Take it to the track and it should be good to go. You still might want to try a receiver cap anyway though.

I should have gone into a little more detail. If you are sensing glitching when you are pulling the trigger and steering too then it is a brown out for sure. Seems like a lot of motors pull high amps and couple that with high power servos and you are stressing the internal BEC of the ESC.

The capacitor stores a little energy and gives it up when the demand for power is high at the receiver.

Good thought, but I fly airplanes with a DSM2 transmitter all the time there. So I'm pretty sure that is not the problem.

I will order one of those capaciters though.

Thanks for the help

Airplane receivers have a different protocol and have brown out protection built in. At least that's what it said on the specs of the rx I'm using for my heli.
