frequency interference and "stutter"
 

Hi,

our racing group has been racing five cars at a time, and we find we get lots of spillover between 45 and 49 mhz, and even sometimes with other frequencies. We also have some problems with what we perceive as "dead zones" on our track, where several cars will, every lap, just sort of "stall" or "stutter" as they go past a certain area of the track. For the 45/49 problem, when the two cars get close to each other, they seem to stall out, or have control interference one with the other. Moving the two people and controllers to different areas of the table (we are running on a large dining room table with a track atop it) seemed to effect the amount of interference a bit, but not alleviate it altogether. Anyone have any suggestions as to avoiding this problem and still being able to race five at a time?

well Rex I am a avad racer like you and your team.....I have a team too....and I have to say my team was very anxious to race otehr racers once they saw your Figure 8 track and almost droped....but we are oval track racers and we still suffer from these 'Dead Zones" as u call them (cool name BTY)......were not sure what cuases them but we do know were they are.

As for overlaping freq.....yeh we also suffer from that too...even diff freq cars like a 35 vs 45.......what happend was that one car had the antenna mod and Crip Crap mod done to it and the other only had the antenaa extension mod alowing from easy pickup (WHEN REALLY CLOSE ONLY) of the other feq controller

the 49 and 45 will over lap only cuas (I think) of the type of antenana on the zip zap....its stronger and than the thin one from TOMY...... I will be try soething though I bougt the 40mhz Compact Char-g and will be getting a TOMY microsizer 49 and see if the effects are the same...

Yeah, "cross-over" can be a real pain. My 27MHz Microsizer will take over any 49MHz car if they get within 5" of each other. :mad:

perhaps that is one of the reasons tomy keep putting crip caps on the controller and revising it. (not sure) .... but if all of your bit's a newer ones , original JDM tomys , and no modifications on the controller and the cars (crip cap). does this still happen?

I don't understand why the 27mhz and 49mhz microsizer can croosover though, but my 27mhz NSX (unmodified tx) dose tend to get interferance from other places

For what it's worth..

I have the 4 Special Edition GT-R's (27/35/45/57MHz) and can run them all in close proximity of one another without any trouble (knock on wood). They all seem to get between 10-15 feet of range too! Perfect for racing around my living room.

hi:) did you do any mods to them to increase their range? Ijust want to know if that is the cons of the mods

No. No mods at all, however, my 35MHz chassis started stuttering a lot. It seems to happen then most in one corner of my living room where there is nothing but my coax for my cable running along the baseboard. Lifted that out of the way (which I didn't expect to change anything...I mean, it *IS* shielded like crazy) and it didn't help at all. Can't figure out what could possibly be under the floor there, and the corner is met on the other side of the wall by a closet. So I am stumped.
