This is a complete no-brainer. The Spektrum receiver placement is not critical at all. Its only a little bit of an issue if there is a lot of CF in the model, but that also easy to get around by moving the remotes till the reception is best.

We've flow it it many different types of models in different configurations and it just works. Personally, I will never fly anything but Spektrum 2.4 again in anything.

I'm not going to get into any war on here and I not am going to say any more on this, but daggets the information you stated regarding Spektrum and how it works is simply very much INCORRECT.
