Model Forum / Radio Controlled / Land Models / November 2006Excuse my ignorance
I presently own a Duratrax Evader electric buggy RTR which came with the standard Futaba AM radio. If I buy a car kit and have to purchase a ESC and receiver separately, can I purchase a receiver which is the exact frequency to put in the kit so I can use my Futaba radio with the new kit. When it comes to radio matters and R/C electronics, I know very little. Can the frequency in my Futaba radio be easily changed by changing the crystal? >From reading, I know that the FM radios are preferable to AM and the 2.4 ghz radios are best. Thanks for any advice.

If I buy a car kit and have to purchase [quoted text clipped - 13 lines] : : Mr. Darian Rachal I do believe futaba do a 27mhz am system receiver for £18.99. Simply put the reciever crystal into your new car and it will work or buy a new pair of crystals. Yes you could do that..or I would simply just buy another DuraTrax (Futaba) or cheap radio. They are a bit better than strictly standard AM 27Mhz which would only be 6 available channels(crystals). Being they are AM 75Mhz. (alot more crystal choices) You can find them pretty cheap, receiver and transmitter, on eBay. http://search.ebay.com/search/search.dll?sofocus=bs&sbrftog=1&catref=C6&frpp=50& from=R10&satitle=duratrax+radio&sacat=2562%26catref%3DC6&sargn=-1%26saslc%3D2&sa dis=200&fpos=27009&ftrt=1&ftrv=1&saprclo=&saprchi=&fsop=1%26fsoo%3D1&coaction=co mpare&copagenum=1&coentrypage=search Or for really cheap option for receiver and transmitter you could go with a strictly AM 27Mhz setup..like that are easily available from Ofna kits http://cgi.ebay.com/OFNA-RAVAGER-CRYSTALS-RECEIVER-Pistol-Grip-2-Ch-RADIO_W0QQit emZ140058078880QQihZ004QQcategoryZ44028QQrdZ1QQcmdZViewItem http://cgi.ebay.com/RC-radio-control-AM-27mhz-Transmitter-Receiver-OFNA_W0QQitem Z160054812807QQihZ006QQcategoryZ34063QQrdZ1QQssPageNameZWD1VQQcmdZViewItem http://cgi.ebay.com/OFNA-ULTRA-COMP2-Pistol-Grip-RADIO-RECEIVER-CRYSTALS_W0QQite mZ140057050013QQihZ004QQcategoryZ44028QQrdZ1QQcmdZViewItem http://cgi.ebay.com/OFNA-HYPER7-2-Channel-Pistol-RADIO-RECEIVER-CRYSTALS_W0QQite mZ140058069201QQihZ004QQcategoryZ44028QQrdZ1QQcmdZViewItem http://cgi.ebay.com/OFNA-MUTILATOR-2-CHANNEL-PISTOL-GRIP-RADIO-RECEIVER_W0QQitem Z140056649236QQihZ004QQcategoryZ44028QQrdZ1QQcmdZViewItem > I presently own a Duratrax Evader electric buggy RTR which came with > the standard Futaba AM radio.

[quoted text clipped - 33 lines] > > > > Mr. Darian Rachal Hi Folks, new to the R/C scene but not to modelmaking I recently acquired two r/c 'toys' which need some attention, one is an unused BMW Z4 with no transmitter and the other a quite quick Subaru with a steering problem which is fixable when I have time to strip it all down. My first job is to get the Z4 sorted for my grandson and although I have spare 27Mhz transmitters the receiver is an unknown quantity as I have no idea what 27 Mhz band frequency it is on and there is no crystal on the board only a pot, if I switch the transmitter on with one of the sticks wedged over to provide a signal can the pot be retuned to accept the signal? is it possible to replace the pot with a crystal?. The Impreza is quite fast for an electric and fairly well made with a lightweight body shell so may keep that one to play with myself once it is sorted, best regards, Terry  SignatureCaliph Ship Models UK. : Hi Folks, : new to the R/C scene but not to modelmaking I recently [quoted text clipped - 12 lines] : : best regards, Terry i said to someone else how about a new futuaba receiver for £18.99 from www.hurricanemodels.co.uk you might also want to find the original manufacturer of the car. The message <HhHah.66258$Ib.36187@newsfe1-gui.ntli.net> from "ian" <r.lincoln@ntlworld.com> contains these words: > you might also want to find the original manufacturer of the car. Hi Ian, the usual 'made in China' and no manufacturers name anywhere on chassis, PCB or anywhere else, I scrapped a 1:12 scale Mini few months ago so have a transmitter with a 27.145 crystal in it so all I need to do is get the Z4 tuned into it, if all else fails I can doctor the Mini PCB and hope it will drive the motor etc which it should do I think. The Mini decided to test some concrete for density one day and totalled the front end and I couldnt find spares to repair it so it became an organ donor to other projects, regards, Terry : The message <HhHah.66258$Ib.36187@newsfe1-gui.ntli.net> : from "ian" <r.lincoln@ntlworld.com> contains these words: [quoted text clipped - 13 lines] : : regards, Terry I would have checked the box it came in. i know someone who races 12 scale minis, he has an xray and a corally. spares are hard to come by for the xray but he found the xray t1 05 10 scale touring car chassis did rather well.

No box I am afraid, everyone around here has gone nitro-mad so electrics are old news and I can pick good quality cars up for a song right now but a problem with most of them is they have been robbed of some of the electrics like servo's and such, need a speed controller for a 1:12 Mitsubishi Lancer which will need to be on the small side to get into the chassis, regards, Terry : The message <VjJah.37309$GX2.24516@newsfe7-gui.ntli.net> : from "ian" <r.lincoln@ntlworld.com> contains these words: [quoted text clipped - 12 lines] : : regards, Terry servos are easy. check hurricane again. prices start at 8.99 i think. also www.modelsinmotion.co.uk have a very good easy to navigate site. For electric cars an electronic speed controller would be easy. very small would be the lrp water proof one. I have one in my 1:18 car. Nitro cars usually have a mechanical one with a servo operating the throttle. |
