    Hey Guys,

    Any links for some cheap main struts for the Falcon or Tornado? I came across these but wasn't sure if anyone gave them a try?? I fly from grass as well.

    Thanks,

    Looked at these before, going by the measurements they are a bit short, asked what dia the strut itself was but no one replied.

    RE: Bob Cat Copy Falcon 120 Jet

    I have a couple sets of these struts. I wouldnt use them on this plane as a turbine setup. IMO its too much weight for them. They are fine for Id say 12-13 pounds or less.

    Has anyone used Savox servos in the Falcon all around? If so what numbers?

    I use these from Trim aircraft. About $180. Email tony and he will send you details, plus they are excellent quality. I have them on a set of Dreamworks oleos.

    RE: Bob Cat Copy Falcon 120 Jet

    Do you know a Falcon 120 retailer in Europe?

    Lindinger in Austria was selling it at €199 with free shippng in Europe, but they are out stock.

    Also a reliable Chinnese retailer that ships to Europe is welcomed.

    Not for the Falcon, but the Tornado a Falcon derivative with lots of upgrades to make it turbine ready can be obtained from : http://www.modellbauuk.com/tornado-v...vt80-241-p.asp

    RE: Bob Cat Copy Falcon 120 Jet

    Well today My Falcon 120 Rabbit VT 90 clocked 384kp out of a low grade DIVE not straight down the feild not possible.
    Useing a Voltron meter GPS The first flight did not set Voltron correct 2nd go reg., 331kp 3rd well 384kp., Magic.

    A GOOD day. One main gear let go on last langing causing lh main to turn 90deg like a sideways brake. The strut just straight up and down type.
    CHEAP and dead set easy fix.

    Boxing Day next time flying, today was its 25th flight.Now priced at $204 a flight till now.

    IT WILL COME DOWN won't it D's that is.

    RE: Bob Cat Copy Falcon 120 Jet

    I believe that any of these single shot, max speed memory devices is a complete waste of time. I looked up the website, and there is no information except that it is more accurate than the previous version.
    Accuracy will depend a bit on the frame rate. They work by calculating the position, then calculating another position, then calculating the distance between those 2 positions and dividing by the time interval to get the average speed.

    If the time interval is very short, then the two positions will be close together and the line between them will be short and almost straight. The trouble is that the positions have a random error. Is the positional error plus or minus 1 metre or 5 metres or what? So if position A is calculated 1 metre too far forward, and position B 1 metre too far back, then the distance error is 2 metres and if the time interval is very short you get a large speed error. Too fast, or too slow.

    If the time interval is very long then the position error doesn't matter so much, but in a turn or loop the distance between the two points (straight line) will be shorter than the flight path, so the speed calculated will be wrong (too slow).

    The only valid speed data you can obtain from GPS would be a continuous graph of speed (ground speed obviously), so that you can spooth out the spikes and dips due to position errors.

    I have used an Eagletree GPS add-on to their data recorder and obtained some useful data. The data can be downloaded as a continuous stream that can be graphed. You can also download heading data (so you know which bits are upwind and which downwind) and if memory serves you can even download the number of satelites locked.
    I found that the graph of groundspeed had many spikes and dips, and if I turned with too much bank the number of satelites used dropped and so did the accuracy, while if I rolled or looped I lost the signal altogether. Even a tight turn could lose the satelites.

    You can only believe GPS speed data if it is averaged from part of a continuous data stream.
    A single maximum spike is laughable nonsense.

    I've seen falcon120's with k-80 radar'd at 160mph flat chat with a dive so about 260kph

    Alastair is very correct on GPS error on speed calculation over the sort term. Flying fpv with GPS data onscreen will quickly show you what he is talking about

    Thanks

    Just popped the swept back turbine mounts and thicker canopies on my website.

    Turbine mount has the required amount of down thrust plus allows a FOD guard to be used. No need to dremel the rear fairing and wooden brace away.

    RE: Bob Cat Copy Falcon 120 Jet

    Got a couple bites,
    ME to don't buy it as well but VOLTRON might not agree.I have all the Eagle Tree gear and able to graph it will get to it one day.
    Have the air speed tubes as well both ET and spectrum whom I think is made buy ET for spectrum, some of my FPV gear records the flight plus video.We can't get a hit with the radar gun for some reason it's a Bushnell 2. at part power we get readings of 212 use more thr.,full power nothing
    I'll get to it But we did have FUN name of the game

    RE: Bob Cat Copy Falcon 120 Jet

    The latest Eagletree data recorders are very good for accuracy, and easy to use.
    You can download the data as a stream and analyse it. You can spot and eliminate obvious errors.
    If you couple the GPS add-on you can corroborate some of the readings and get a heading (or rather track) readout which helps you tell which bit of the readout is for which bit of the flight. I recorded flap position for the same purpose.

    The big problem is getting a reliable static pressure source. In my model I used the supplied pitot/static probe. But my height readings turned out wrong at high speed. In a high speed pass at 10 feet above the runway, the data recorder claimed it was 80 feet below the runway. Because of the error in the static pressure the speed calculated was underestimated, but the superimposed GPS speed trace helps make sense of the numbers.
    The speed and height readouts when landing, or stalling high up, seem to be spot-on.
