well thanks for that little gem,the radio is not faulty it just has a range issue.reading all the data from other users it appears this is a fault with this spectrum radio that is ongoing,perhaps spectrum will refund my money lol,just another case of i've got your money now the problem is yours,which brings me to the original question can anyone recommend a radio with a good distance 200 meters plus?

contacted spectrum uk and explained the problem,the answer is quite simple extend the AE,so i did approx 10'' in total cured the problem can now run at least 200 yards ran out of running space so i don't know how much farther it will go, total cost £1.00 cheap solution

You need to check the inside of your receiver for any magnetic soil in the unit itself,mostly those buggies,trucks and smashers.This dirt will magnetize to your chips,diodes,regulators and such will effect the RF signal from the transmitter that is trying to make a pulse code modulation signal back to the receiver end.If there is no sign of dirt or magnetized soil or dirt, if you do see magnetized soil,use an air compressor with and a safety googles and blow out the particles in it,then check your receiver antenna connection where is is soldered.If that looks good,check your connection from all your ESC and steering servo.If that looks good,then I would suggest using a seperate battery supply ( BEC) to the receiver instead from the main battery as the supplier to it.Now those that have carbon fiber bottom pans,must take note that static's can be present from the carbon fiber plates,if no carbon fiber pan,then check your transmitter power level,even if it even if it was charge for a long time,allways check every 2 minutes on the transmitter power, as it my have a bad battery cell maybe. Now my opinion on 2.4 mhz radio's version's is not my cup of tea.The wide 2.4 spread spectrum radio's of the frequencies is so so,due to alot of RF in the air that uses 2.4 mhz frequencies from broadband signals from other sources of appliances nearby...........Then you have cell phones and microwave RF signals towers of commercial nearby can also effect your 2.4 signal. Those cell phone repeaters do send out high power RF signals that is close to the frequency of the radio.Then those big power lines in the area will effect your radio.........Remember now,with the newer 2.4 mhz radio's ,this units are in the micro wave frequency band waves......On the antenna lenght,I've never heard of 10'' or 8.5''long,when this are too long,they will pickup unwanted signals to your receiver end......2.4 mhz are only a couple of inches long,maybe your rado is in the 75 mhz......you didn't mention it what band it was on..........If all does not pertain the problem,then you need to send out you radio system back to the manufacture and have them recalibrate and check the RF signals from the transmitter and receiver.
