    Hi Francis

    If the old one is completely knackered, and it's not too dangerous to take apart (if it is, please don't do it) I wouldn't mind seeing some piccies of the guts of it. Being a sad engineer type I just love being curious about this sort of stuff.

    On the subject of motorbike forks..... a long time ago when I was 17 (a very long time ago) I was changing the fork oil on my bike. Removed the drain screws at the bottom of the fork on both legs. Oil dribbles out. Too slow for me. So I leant on the handle bars to "help" the oil out.

    It's amazing how far the oil goes horizontally when you do that. :oops::oops::shock::oops::oops:

    Flying 2 cv

    Dissing BMW. No, fine examples of German engineering. I was meerly point out that the 2CV body is much smaller and lighter than a BMW body as the BMW's tend to be more roomy inside and more structurally sound if you are involved in a crash. Fine luxury vehicles.

    Where as the 2CV is perfect for your farmer carrying eggs to market.

    :D

    phew, got away with that, don't think anyone noticed, I best be off!!!!! :lol:

    safety advisory DHV - legs straps

    This issue occurance could possibly be reduced by using an edge strip of something less abrasive than carbon.

    Possibly thin rubber or even propeller tape or "helicopter" tape (the tape that is used on the leading edges of props or helicopter blades). The weight gain would be negligable. What do you think Francis?

    I think Francis would agree that, even if your seat board is wooden, the straps should be periodically checked anyway just to be sure.

    Watch out for the first step, it's a biggy. :D

    A re-enforced crash helmet will protect his ears from the thunderous sonic boom he will create as he breaks the sound barrier.

    On a serious note. Will he hear the sonic boom? or is this journalistic licence in that the wind noise at subsonic speeds will be deafening? (Until he reaches the normal terminal velocity when the air density increases) I'm not sure.

    Good luck to him.

    Difference between RAD MXL and RXL

    in Paramotors.

    Hi Arcus Flyer

    The RXL is a smaller machine.

    From the original spec sheets and when new the following data applied:

    Static thrust: RXL 43 Kg MXL 47 Kg

    Weight (Zero fuel): RXL 15 Kg MXL 17.5 Kg

    Prop diameter: RXL 0.9 m MXL 1.05 m

    I have recently tested some older MXL's and the best thrust figure attained was 42 Kg so please don't expect an old unit to produce "book" figures. That will all depend on usage and how the machine has been looked after.

    Spares will become increasingly difficult to obtain as the cost of stocking them when weighed against the amount sold becomes difficult to sanction. They would always be available, but manufacturing 1 or 2 off a part is prohibitively expensive.

    My advise would be to buy a new RAD Arrow or Javelin. But I am biased.
