Barry Taylor Posted March 23, 2009 Share Posted March 23, 2009 Hi, I have a couple of Optic 6 transmitters that currently operate on 35mhz. I would like to be able to convert to 2.4ghz but Hitec don't seem to do a 2.4ghz conversion module yet. However, in the April issue of RCME, a gentleman recently sold a Hitec Optic 6 tranny that was, he claimed, fitted with a Spektrum conversion module, presumably DSM2, that is designed for converting Futaba radios. I contacted him and he said he got his from Robotbirds, it fit the Hitec module socket in the Hitec tranny and worked perfectly with the spectrum receiver that was supplied with it. I have contacted Robotbirds about this and they say that it only works with Futaba radios. Can anybody shed some light on this please as the conversion kits are a little too expensive to buy without knowing for certain? Cheers Quote Link to comment Share on other sites More sharing options...

Barry Taylor Posted March 24, 2009 Author Share Posted March 24, 2009 Thanks for the info Paul, will check out Puffin's site. Would still like to know if Spektrum gear will work as it seems odd that the chap who sold the gear was adamant it did. Quote Link to comment Share on other sites More sharing options...
Chris 75 Posted March 25, 2009 Share Posted March 25, 2009 I have this from another forum but haven't tried it myself. The Futaba Spektrum module works in the Optic if the transmitter is set to PPM/negative. Is it permitted to link to other forum discussions? If not I guess that someone will tell me - please delete if inappropriate: http://www.rcgroups.com/forums/showthread.php?t=907994 Quote Link to comment Share on other sites More sharing options...
Barry Taylor Posted March 25, 2009 Author Share Posted March 25, 2009 Hi Chris, Thanks for the link. Despite what Robotbirds are saying, it would seem that the Spektrum Air Modules for Futaba (DSM2 type) do indeed work ok in Optic 6 trannies. This is bril because it will be a cheaper alternative than buying overpriced Futaba 2.4 receivers. Quote Link to comment Share on other sites More sharing options...
