ryanb741 0 Posted February 25, 2003 Can I mix a Futaba receiver with an acoms transmitter and Sanwa servos (as an example) or do all radio gear components need to be from the same brand? Share this post Link to post Share on other sites
James 0 Posted February 25, 2003 Helping out a newbie! I feel like Superman! [] Er... anyway.... As long as all the Radio is on the same frequency then that's OK. For example an ACOMS 27mhz Transmitter + Futaba R122JE 27mhz Receiver + HiTec Standard servo - will work as a combo fine. Main thing to remember is to use the Transmitter Brand of crystals. This isn't an issue with 27mhz (as all 27mhz 'colour' crystals are universal) BUT with 40mhz, make sure the Radio has it's own crystals, irrespective of the reciever used (Example - KO Vantage MUST use KO Crystals / Futaba 3VC MUST use Futaba crystals and so on...) Hope that explained things. [] Share this post Link to post Share on other sites
ryanb741 0 Posted February 25, 2003 Many thanks. I'm kind of a newbie - I was really into R/C (Tamiya) when I lived in Australia but then moved to the UK and forgot about R/C for about 15 years until a fateful trip to the top floor at Hamley's! Now I'm hooked again, and there's just so many to get! Share this post Link to post Share on other sites
James 0 Posted February 25, 2003 OOOOOOOhhhh! Ryan! Seriously - did Hamley's get you hooked? I've got TONS (!!!!!!!!!!!!!!!!) of experience from them, due to being in a London hospital a lot and walking there eveyday as 'entertainment'. The Tamiya Bloke there is a real sour-face, but the display is pretty impressive! Maybe you can e-mail me and we'll discuss this further, because I've a few 'tips' regarding purchases from Hamleys.... Share this post Link to post Share on other sites
ryanb741 0 Posted February 25, 2003 Well - Hamley's is quite pricey (I paid £150 for a Wild Dagger kit) but one of the guys who works on the Tamiya counter is pretty cool. Annoying thing is, when I bought a Mad Bull there, he removed the box from the back shelf to give to me and what did I see behind - a MAdcap box (now discontinued). Obviously I asked to buy that one instead but he wouldn't sell it to me as it was discontinued and was supposed to have been sent back to their storage depot for disposal. I was offering to pay £100 for it and yet they were just going to throw it away as it was company 'policy'. ******..... Share this post Link to post Share on other sites

[] AM gear is usually no problem to interchange between brands. Your xtals need to be matching freq pairs, of course. You may have more difficulty swapping around FM & PCM radio gear as the receiver has to match what the transmitter is sending out; some TXes are switchable between modes too. There are also different flavours of FM... which is only where *brands* come into play. Mixing AM & FM gear plain just won't work. Putting AM xtals into FM gear usually damages some electronics. The actual frequency themselves is just a carrier and does not denote AM/FM etc. You can get AM & FM on all freqs if you go looking around the world. When changing freqs, the radio set is 'tuned' for a certain band, say 27Mhz. Putting a different band (say 29, 40, 72) will severely detune the equipment to the point of uselessness. If you're swapping xtals, swap only within that band, say between 26.995 to 27.255 only. Share this post Link to post Share on other sites
limas_mtb 0 Posted February 26, 2003 Oooops! I remember putting some wrong crystals in my TX once, hope nothing was damaged! Running 40MHz AM, I rarely need an extra set of crystals, as no one else seems to run this freq.[] Share this post Link to post Share on other sites

[] Don't worry, if radio gear is damaged it just plain won't work. If it continues to work then its probably undamaged. If you really want to be sure just do a range check... too lazy to do it on foot I just drive my car as far away as possible with the TX antenna down. (ESC equipped car of course... don't do it with a MSC or nitro car! [:0]) Share this post Link to post Share on other sites
limas_mtb 0 Posted February 26, 2003 Well, as far as I know, there is no restriction for the band I'm using. I bought my Acoms Hayabusha radio from the Greek Tamiya distributor. The army & police in Greece use 80-86MHz FM freq as I am told. Another fact is that I never seem to have any radio-interference, while my mates running 27MHz AM suffer quite a bit[] Share this post Link to post Share on other sites
