well thanks for all the help everybody i finally put it all together tonight and it seems to be working OK . the only problem i had was when i pushed the id set button on the r7eh receiver with a cocktail stick it fell off the board. :-( now its not the biggest of buttons but i soldered it back on using the big lens from my binoculars and my glasses on but it worked . channel 3 on the receiver does not work Ive tried all servos and esc in it and nothing but as i only needed 3 channels I'm happy with it.
I note that there is a warning in the addition to the review:
"..While the majority of people enthuse about the kit, some forum members complain about poor quality control, especially poor soldering of wires. At these prices it is likely that manufacturers quality control is non-existent, or limited to a single check that the product works at the end of the assembly line. Consequently, I think it is a good idea to open up the Tx and check that the internal connecting wires are reasonably well soldered before initial use - improving where necessary..."
I have heard other people commenting that one of their receiver channels did not work - they opened it up, cleaned the solder which was bridging a connection away and the channel was then fine. But the advantage of buying from GC is that they will happily replace any item which is faulty, so you could contact the company and get a fully working receiver if you wish. They may be a little unhappy if you've been resoldering items inside it, but it's worth a try...
