Antennas tend to unplug from the receiver board due to vibrations.
Open receiver, check if the antennas are still well fitted, secure them with a drop of hotglue, and enlarge receiver case antenna exit holes, to remove any mechanical tension that could exist and put a force on antenna plug.
But, if range check of both receivers returned the same range, at least 50 meters, then the problem is in your model setup.
I already posted here on this subject, the 90 degrees rule is highly misunderstood. For example, placing one antenna along a wing, the other along the fuselage and Tx antenna vertically is a guaranteed recipe for lost link in some hundred meters.

In this case, whatever you fly place the Tx antenna also horizontal, i.e. pointing lateral left or right.

If both receivers, tested side by side give you the same distance in reduced power range check mode, then the only reason I can think is how antennas are mounted in the plane, and plane build (any carbon?)
For a good return policy, next time no more buy from hk, if in US you have a good local seller, alofthobbies, offering at hk prices a lot more support.

yesterday i did check the both Orange rx side by side in Powerdown mode to check its range n the both rx hv different range not the same the first one which had the problem has low range while the other have long n the difference about 50M i was walk away form the models about 100 m while the first one start glitches from 30 M and stop responding at about 55 to 60M while the other still in contact with the rx while i was at 100M away from the Model.

i place my model away from my vehicle (from metal) and both model are made by Ply n balsa. model are about 2 feet Ht from the Ground. now tell me what next

Then you might have an antenna issue the most probably...
No signs of the antenna wire due to a past bending over a sharp edge ?
I would replace both antennas, they are too cheap for guesses.
