  1. 'someone' noticed I was not co-ordinating my turns correctly - he showed me what happens (in a Drifter) when you wash off speed in an un-coordinated climbing turn (as you could do climbing away after a take-off)the Drifter virtually flicked inverted and it took 700 feet for a full recovery - and then he said "now imagine what would happen if you did that at 500 feet in the circuit, David"

    as an instructor he is a demon on airspeed and co-ordination in turns, which may be something to do with the fact that I'm still here.....which brings me to this:

     

    did anyone else notice the article in the latest Sport Pilot magazine, where it was stated in an aircraft flight review: "The instrument panel is missing a balance ball so you can never be flying out of balance, or indeed in balance".

     

    this is obviously a flippant comment, but I do wonder about the lack of balance information being communicated to the pilot

     

    This was in relation to a pusher prop aircraft, so (as per on Drifters) the little piece of red wool taped to the bottom of the 'screen gives you all the info you need as far as 'balance' is concerned...

    How do we ride bikes, fly no ball thruster's or ski without the aid of the ball ?

     

     

  2. Hi Greg, if you haven't already check out Tucker Gott paramotor he sometimes flies in remote areas. Easy transport and as close to a flying bike as you will get. The most important thing is get good training for the type of flying you will be doing.

  3. Why is the Thruster family a bit touchy on ground handling ?Well the issue is primarily one of wheels too far forward of the cofg so once it starts to wiggle it wags really strongly.

     

    The bigger two seaters are worse than the Single seaters and the reasons are:

     

    1. For construction simplicity the springs come straight off the bottom of the Aframe and for simplicity that frame is in the plane of the leading edge.

     

    2. The two seaters have higher Aframes and longer spring legs - higher ground angle and also moves the cofg on the ground even further rearward of the mains

     

    1. And 2. Mean it’s set up to swing easily into a ground loop

     

    Add in 3. The fact that the main legs are springs with absolutely zero damping and they are long. The wiggles start easily with this leg setup and are compounded by the undercarriage geometry.

     

    So basically you probably couldn’t design a worse/more susceptible to ground loop undercarriage without a lot of effort !!!

     

    Having said that I did a few flights in a t500 two weeks ago and the grin is still with me so go figure - love the Thruster and just get a good training in it for its behaviours.

     

    How would a better solution look on a Thruster ? - have the main legs closer to the cofg - move the Aframe backward and use v struts to front and back spars. Change the legs from steel springs to be like the UK t600 that uses a tripod leg setup with rubber in compression for suspension

     

    But then again - it wouldn’t be a Thruster and you’d have access issues for pilots if you move the a frame back

    Look at a cessna 180 or Drifter side on it's the same as a Thruster, I have never experienced the Thruster difficulties that people speak of.
