While crystals are different in single and dual convertion receivers, it does not neccesarily mean that the range of a single convertion receiver is lower than a dual convertion receiver, but I guess that in fact it depends on the price that you pay for a particular receiver.

You are absolutely right that "conversion' has nothing to do with range.
The tech notes for the GP Elictrifly receivers specifically say, "Approximately 890 feet of maximum range."
890 feet is only reasonable for a park flier.
The fact that it could be a single convertion receiver (I do not know this particular receiver) is not the reason of the range. The range of receivers becomes of some filters that some manufacturers uses.
In fact Berg receivers are single convertion with full range, which means that you can fly a large plane as long as you can see it and been capable of maneuver it to bring it back.
There are many others single convertion receivers that are not full range, that is why I mentioned the price and quality of the receivers.
The purpose of bringing this back is to make a clearer idea of the difference between the single and double convertion receivers.
Thanks.
