Radios for jets
Hi Guys
Just thought I would share some recent experiences with you regarding the newest line of radio equipment out there. I just got back from some really excellent and well attended jet meets in the U.S. I was surprised by the number of jet guys now using the 2.4 G stuff. Everyone I talked to that were using the technology were very pleased with it. Performance was certainly there as I saw many of the jets fly at extreme distances and really fast! While at the Woodland / Davis meet in California I talked with some of the guys about the newer computer radios and their experience with 2.4 through last season. I was thoroughly impressed with what I had heard. I also had a opportunity to check out some new radios ( Futaba / JR ). Last week I sent my ol trusty 10X back to Horizon for a thorough going over and decided to get a new ( 72 band ) JR 9303 for my Eurofighter ( scale version ) which also has a Wetronics dual receiver. After spending less than an hour with the radio I had my Eurofighter totally programmed with the ability to adjust the canard angles independently for takeoff / cruise mode. Having played with crow mixing on a number of jets the last couple of years; I took the time to check out the 9303 capabilities. I was amazed. In less than 10 minutes it was all programmed and working perfectly! So why share this....well having seen the new 2.4 G in jets and the newest radio software, I can say with some certainty that our link and ability to program complex functions on our jets has just become all that much better! BTW,I have no affiliation with any radio manufacturer - just thought I would share this info. One thing I am looking forward to - no more long antenna leads in the fuse!!! Dean W. |

Gotta agree with you Dean,
I've done some testing of my own on the DX-7 over the last couple months. I'm not running a jet with it (yet...), but I can comment on the 2.4 GHz Spectrum hardware performing well in dirty RF environments. Its currently being used on the Sandman Hotels Arena blimp at BC Lions home games in BC Place. Last game had ~37,000 people in attendance; many, many, many cell phones likely operating inside an enclosed structure while we're flying pre-game and at 1/2 time. In 4 games I haven't been able to detect a hint of radio trouble or lost frames in the transmissions, flying in some cases several hundred feet away. Also of note, as supplied a few of the fan motors did not even have capacitors installed, which further shows the robustness of the link in dealing with RF noise. I thought for sure this would push the limits enough to give a rough estimate of where the line was drawn in the sand, but the technology hasn't missed a beat and it's really impressed me so far.

Dean.. are you using the programming features of the Wheatronics, or using the 9303's capabilities?

Hi Wayne
A combination of both. I use the Weatronics to set neutral points and designate individual servo application but still have to use the elevon / flaperon function in the 9303. The combination of the two has eleminated all matchboxes, amplified leads and extra battery monitoring stuff. The eurofighter is the most complex model that I have done to date. I took an original Fibreclassics Eurofighter and added: Full intake Custom canard pivot blocks Bifurcated exhaust Tam's exhaust cones Full depth scale cockpit with lighting system Dorsal brake Full landing gear door pack Nav, landing, strobe and cockpit lights Nose probes / fuel probe / Pirate module Individual flight surface servo Added surface detailing Laser cut intake detailing Titan SE powered Electronics: 2 servos per wing rudder servo nosewheel servo retract solonoid brake solonoid 2 canard servos lighting servo ( nav, strobe, landing and cockpit lights ) dorsal speedbrake actuator servo Its been a four year project ( on and off ) but given how my first one flew I am confident that it will perform nicely!

Oh yes...the CARF Eurofighter is a favorite bird. I saw an early prototype fly at Superman in 2000 and it was amazing. The bird definitely requires thrust but it has the most statble platform of any jet I have flown. A lot of guys tend to baby it around and not fly it to its full potential. The Eurofighter is in its element when flown slow, high alpha with lots of throw added in. She'll do amazing quick rolls and super tight loops. She will not snap, spin or do any funky unexpected stuff. Once you get over the big bird " has to fly fast " thing then the fun really begins!

Radios for Jets,
Reading all the possatives,and good reviews about the new 2.4 Radios I feel confident about the Spectrum7, I won at the Fall float fly. I'm presently using it in my small Bobcat and have purchased another reciever 7ch for my YAK, it has proven, so far to be very reliable and comfortable to fly. Thanks Dean , Thanks Kelly, By the time the spring rally is here maybe I'll fly my new Rookie with it.
