HPI Vorza Stock Receiver binded to Spektrum DX3C Radio?

[Chris_H]

I've got an HPI vorza, I've also got the DX3C and the Receiver that comes with it. The receiver antenna is tiny, it has hardly any length to allow it into the antenna tube. I installed it in the Vorza and find that the buggy now has far less range than it used to have. The safety cut of kicks in when the buggy is out of range.

 

When I had just the stock HPI Vorza radio and receiver it would go much further than it does now. I'm assuming the shorter antenna is to blame?

 

So I was thinking about putting the Vorza receiver back into it, would it bind with the Spektrum radio? Or only work with the Vorza Radio? I can go back to the Vorza radio, but it doesn't look as good as the Spektrum radio and kind of defeats the purpose of buying the after market radio in the first place.

 

Cheers,

No if won't you need the specific RX/TX

Ok thanks for the reply. Is there a better receiver with a longer antenna aerial I can buy to give longer range? That would work with the DX3C? The one that came with it is rubbish, small Aerial and small range...

Maybe the orange Rx from Hobbyking.

The OrangeRX GR300 is also pretty short, like about 6-7cm long

Have you tried taking it out of the tube from the length you describe it sound like you have a similar receiver to me although mine is a non branded one I can get a good 500 - 600m Range on an open field (And that's only as I reach a building a one end and the trees there I am stood). Have you tried running it somewhere wide and open the signal should travel better if there are no obstacles especially if they contain hight amounts of water as the 2.4GHz frequency has real trouble penetrating.

If you talk to people it's not uncommon to see weird signal drops with Spektrum gear. I have been running OrangeRx receivers in my last few models and despite the short aeriel they seem to be more stable than some of the Spekky receiver I have run.

 

Remember the aeriel length is determined by the signal frequency. A frequency of 2.4Ghz gives a wavelength of 12.5cm.

 

Also aeriel orientation in the Tx and Rx should match (i,e. aeriel pointing up vertical in the model, and pointing up vertical in the Rx)
