But I like sniffing chemicals....
Interim update:
Hobbycity order arrived today, got all my wires and whatnot, along with the servo; damn, what a beaut. Was planning on testing it quickly this evening & doping to clearance work on the truck's steering mech, but I ended up helping my little sister & her boyfriend moving into their new flat (apartment)- nice place actually. Hopefully at the weekend I will make some more progress, rig the steering up and see how much throw I have after the tweaks.
Question: I bought a spare rx for my 40mhz hitec laser 6 radio, exact same model (RCD3500) as my existing one. I swapped over the crystal (no binding issues here

) and hooked the rx upto the MMM in the Gmaxx just for testing; I get the first 3 rapid beeps, but then nothing, like the esc isnt getting a signal from the rx (same as when the tx is left turned off when turning on the esc). I wouldnt need to recalibrate the esc to the rado just because Im using a different, but the same, rx would I? I would wager not, but that leaves me wondering why this new (but old) rx wont work- only difference between it & my old one is that the antenna is ornage instead of the usual black. Makes me think it may have been replaced at some point and now may be damaged internally? The seller says its a 40mhz rx, but the little label is worn off- would there be anything inside the rx casing to ID the frequency, like on the pcb or not?
Though it may be somewhat illegal technically, is it possible to retune the rx at home- believe its one or two pot type components inside, or would I need an oscilator to make sure the fequency is precise; if thats the case, then I have a new paperweight I guess
