John Laverick Posted June 12, 2016 Share Posted June 12, 2016 I have been using 35mhz and have been very reluctant to make the switch to 2.4mhz. Mainly cos I was scared I wouldn't understand the technology, and I have 20 plus models with 35mhz rx's in em. However I've bit the bullet and bought a TGY i10. Bind a recicever!!! WTF is bind a reciever, it should just work shouldn't it? I've re_read the instructions, done as they say, and I can honestly say, it's a different level! ! Ok, I've bought an entry level TX, But once you understand what's going on, Wow!!!! It's fabulous, so intuitive and so easy to follow. Iove it, love it love it!!!

Josip Vrandecic -Mes Posted June 12, 2016 Share Posted June 12, 2016 Hello John , welcome to the club of 2.4....fully understand your enthusiasm because I'm also from the rigid classical modeller became a lover of new technology ..... Just still waiting for news that you get some acrobatic foamy ... lol All the best Jo Edited By Josip Vrandecic -Mes on 12/06/2016 19:32:03 Quote Link to comment Share on other sites More sharing options...

ChrisB Posted June 12, 2016 Share Posted June 12, 2016 I was of the same view John. I decided to select one or two models to initially convert to 2.4 and then anything new, but i've left about 50% of my existing models on 35mhz, partly because of cost but also I then have a spare TX and models should my 2.4 TX go wrong. Also, 35mhz is perfectly good and there is nothing at all wrong with it. That said the new generation of radios are superb and very easy to use and if you fly at shows you can only use 2.4.

Engine Doctor Posted June 12, 2016 Share Posted June 12, 2016 Posted by Percy Verance on 12/06/2016 19:31:40: I still do about 50% of my flying on 35mhz. Indeed, I have several new boxed 35mhz receivers........ I resisted changing to 2.4 until I new more about it . Then bought some 2.4 gear and used my 35 meg stuff as well .The 2.4 controlled models got used more often than the 35 gear as it was easier at the field . Then one day I took off using 35 meg without extending the Tx aerial .So it appears that old habits can die very quickly ! I very quickly extended it and decide that the time had come to retire the 35 meg . Not looked back . Use FrSky Tx modules and rx,s with Futaba FF9 , a 6EXA and a Skysport 6 for my diesel stuff and never had a glitch ,its brilliant. As Percy says Installation is very important with 2.4 so don;t cut any corners . Edited By Engine Doctor on 12/06/2016 21:01:12 Quote Link to comment Share on other sites More sharing options...
Shaunie Posted June 12, 2016 Share Posted June 12, 2016 Hi john, welcome to the 2.4GHz club. Waaay back in the olden days a 35MHz receiver would respond to any transmitter signal it saw on it's frequency. With a 2.4GHz system each transmitter has a GUID (globally unique identity). This code is used to define the frequency hopping sequence for the transmitter. In the process of binding this is passed to the receiver so it also knows where to to hop to continue receiving the signal. In this way your bound receiver responds to your transmitter and no other despite the fact that loads of similar transmitters are right next to you. This is a dramatic over-simplification but is sufficient to understand the basic principles involved. Shaunie. Quote Link to comment Share on other sites More sharing options...
John Privett Posted June 12, 2016 Share Posted June 12, 2016 Probably more importantly, the GUID is sent with each packet of data. When the receiver receives a packet of data it will ignore any that don't have the 'correct' GUID. Quote Link to comment Share on other sites More sharing options...

cymaz Posted June 13, 2016 Share Posted June 13, 2016 John, 2.4ghz is far more robust and less prone to interference when you start to run small 2 stroke petrols in your models. It still amazes me how a Rx be so small but so damn good! Quote Link to comment Share on other sites More sharing options...
Owdlad Posted June 13, 2016 Share Posted June 13, 2016 Welcome to the junk channel............. Big mistake stick to 35 meg Quote Link to comment Share on other sites More sharing options...
gangster Posted June 13, 2016 Share Posted June 13, 2016 Happily using both Never really had any radio related issues on 27 35 or 2.4 in 30 odd years most so called interference or radio related issues are not related to rf or coding Quote Link to comment Share on other sites More sharing options...

John Laverick Posted June 13, 2016 Author Share Posted June 13, 2016 Thanks guys, as it happens I put a speaker system in my old Ripmax mustang last week for testing purposes. I gave it a chuck and it went haywire, totally out of control. luckily it done a greaser the right way up and the only damage was the spinner. I presume the speaker system interfered with the 35mhz RX. Never had a glitch before. It was then that I decided I needed to go 2.4. !!! I've installed 2.4 into the mustang, and I'm just waiting for the weekend to give it a go. Let's hope it works cos the speaker system sounds great and I want to install them in some of my other models John Quote Link to comment Share on other sites More sharing options...
Shaunie Posted June 13, 2016 Share Posted June 13, 2016 John P, as I said "dramatic over-simplification" The big difference as I see it is that with 35MHz interference causes glitching before complete control loss in most cases. With 2.4GHz the systems error checking tends to give near normal performance until total control loss, compounded by the delay before control is re-established. A few years ago I flew a camera equipped plane on 35MHz. When I revised the footage I was amazed at how many twitches and glitches there were. None of these were noticed from my viewpoint on the ground. Shaunie. Quote Link to comment Share on other sites More sharing options...
onetenor Posted June 14, 2016 Share Posted June 14, 2016 Just bought my first 2.4 Rx From Bang Good A microlite DSM2 6 channel . Gear Best also sell them but a bit dearer. I got it as I heard good reports on it and being on low pension it was cheap. Now looking for compatible Tx 6 Channel as cheaply as possible.Suggestions on a post card please Quote Link to comment Share on other sites More sharing options...

will -0 Posted June 14, 2016 Share Posted June 14, 2016 John, the lesson there is to do a proper range check after adding any electrical items to your model or changing the radio set up. That effect should have been picked up on the ground. Quote Link to comment Share on other sites More sharing options...

Postcard on its way Just note that as this is DSM2 it is no longer compliant with the 2.4 regulations, so it won't be CE certified and if it gets held up by customs it may get held, probably not but worth noting. Lots of 2nd hand Spektrum DSM2 transmitters on BMFA though. Quote Link to comment Share on other sites More sharing options...
