Today I was using a 9303 2.4 system thermaling a Supra at the Syosset NY field, the systems reaction speed didn't help much when my batteries ran out :-(. Lucked out with just a ding or two...but the worse part was I didn't get one of the two last 30 minute flights I need to complete the Silver l

One more thing that I discovered yesterday trying to make that 30 all day. My elevator servo stopped working in flight, and I managed to 'land' it three times using flaps to loop it down to flat tall grass landings and once to a soft dirt dork. That Supra is one tough airframe. But in all that,

If you'd all just start using your Talking Timers wheny you 'practice' and have a landing task set up like the zone that will be at your next contest. Its interesting when an RES wooden RES ship like the Big Birdy, Marauder, Grand Esprit or the like, whips up on the entire field of super moldies.

Am I reading this post correctly? I was under the impression that 2.4 was faster not slower than 72mhz and yet you are posting a lower MS latency for 72 tested scenarios which implies faster respnses. Also, the difference between say 35 MS and 69 MS is not something I would easily pass off as un

Very interesting, Ira. Did you happen to do the same test running the 8103 in PCM mode instead of PPM? The other question that everyone has is the latency of the 2.4 module vs the integrated 2.4 system. Do you have any way to test this? Rick -- rhelgeson --
