    Radio Wars, Part 2

    I can only go by my own experience and say that the DSM2 or DSMX links have never caused me any problem at all, not the many guys I know who fly Spektrum. Sure models go down, they did long before Spektrum was ever heard of. DSM2 did have issues in 'noisy' environments (over 40 Tx's working)...

    Radio Wars, Part 2

    Of course that's true, Horizon are never going to test and endorse 'compatible' receivers, it would be cutting their own throats to do so. FWIW I've used a couple of Orange receivers and they seem to be perfectly reliable but I admit for the models I care about I do use genuine Spektrum, which...

    Radio Wars, Part 2

    You were VERY lucky that you were running separate power and radio batteries. It could have been real nasty if you plane had powered up in the pit area, potentially causing a lot of damage to other models and worse still people. It couldn't have happened with Model-Match;)

    Space, Yep, you are right if you wanted to swap Rx's between planes programmed on different memories in the Tx you would have to re-bind, which of course is a process which takes about 10 seconds, i.e. a tiny fraction of the time it takes to physically remove and re connect an Rx:rolleyes: If...

    Picking a power system

    Robin, I think maybe with 3D planes that don't use full throttle for long periods and where weight is especially critical it's safe enough to dispense with the 80% safety factor. My point is that if you use the 'safety factor' for 3D models you end up coming up with a larger, heavier and more...

    Radio Wars, Part 2

    Yep, that's a fair assessment I'd say. A lot will depend on how they feel in your hand and price. Also if you put any value on telemetry and Model-Match (offered by DX8) or the capability to expand to 14 channels (offered by 8FG). You might also want to look at the cost of receivers because if...

    Radio Wars, Part 2

    The data from the testing done to show it was on par with the 8FG would be interesting to see because the table on the thread with the latency tests: http://rc.runryder.com/helicopter/t172571p1/ says that the Aurora was tested with an XPS module. And it was still three times the latency of the...

    RC Radio Latency

    There has been some heated discussion on the forum about what radio gear is the best and one thing that comes up a lot is 'latency'. So what is this latency thing? Technically in RC terms latency is the time taken between moving the stick on the Tx and the servo achieving the commanded...

    Radio Wars, Part 2

    So do you have any data on the effect of the XPS module on overall latency? from what I've read most of the Aurora's latency comes from slow computational time in the transmitter; that is the tx takes a while to process the stick position input and calculate (taking into account rates...

    Radio Wars, Part 2

    As noted above, the DX8 has all the features you would ever want to fly 3D, triple rates, throttle curves, tons of mixes, low latency. I don't think there is any feature that the 8FG has that the DX8 does not (no doubt I'll be corrected on that if I'm wrong). for 3D there is nothing missing at...

    Radio Wars, Part 2

    Space.. I don't think there is anything hard or mysterious in the prediction if we restrict the variables to radio latency alone . If we accept the measurement recorded here: http://rc.runryder.com/helicopter/t172571p1/ (which includes signal processing time etc etc) then distance travelled...

    Picking a power system

    Ok.. in that case I'm pretty sure that the Super Viper example is incorrect as the weight used was excluding battery. If you used the realistic flying weight (in the order of 46oz / 2.9lb) then I think you will end up with very high power figure. For instance substituting the realistic all up...

    Fix for HK Slick 360 Wing Rock

    NJ, Unfortunately I cracked the carbon landing gear on my AJ Slick so it's in the hanger waiting for the spare to arrive (one of the problems buying a plane that's not stocked in the UK). So I haven't had the opportunity to fly them both back to back in the same conditions. Also when I have...

    Picking a power system

    So the weight used has to be weight without battery for this method?

    Seagull ARF's

    The Seagulll model I have experience of is the Innovator trainer which I put together for my flying buddy a while back. It was decent quality and went together well enough and flies very nicely (as a trainer). It was not on the same standard of the EF / 3DHS of this world, but to be fair the...

    Fix for HK Slick 360 Wing Rock

    Flight tested today and i'm delighted:D The big rudder works exactly as intended and has calmed down the wing rock/drop no end. It will still rock a bit if you provoke it but I've yet to find a plane that wont. No matter how hard I tried with my ham fists it's wouldn't drop a wing. Basically...

    Fix for HK Slick 360 Wing Rock

    I got the new rudder built and installed. here are the 'bones' prior to covering with the original rudder for comparison: And here it is covered and installed ready for flight testing.. i actually saved 4g whoo hoo Flight testing tomorrow.
