  1. Hi,

    I’m considering the Vittorazi Fly 100 EVO as an alternative to the Mosquito NRG and have some questions that I hope you can answer.

    While packed, what are the dimensions and weight?
    Is it possible to order the EVO with an extended shaft (+15cm)?
    Are there any retailers in Scandinavia for spare parts?
    What is the price for å EVO with a folded propeller and parachute?

    Best regards

    1. Hi Kristian,
      Packed size is 225cm long
      57 cm depth at engine area
      44 cm depth at foot area of harness
      45 cm depth at pilots waist point
      46 cm width at leg mounting brackets
      66 cm width at wheel mounting points, legs folded into frame clips.
      note that front harness section is dismounted from frame and travels in its own storage bag
      this allows for much easier transporting and rear section can be stored in vertical position
      sitting on frame tube ends which have protective caps for this purpose so unit takes up very little floor space
      about the same as a person standing.front section can be stored in the home which is better for the parachute if fitted as temp and humidity is more stable.
      weight is around 37 kg .
      It is possible to have a longer drive shaft fitted at the build stage.
      No Wasp agents in Scandi but engine parts can be purchased direct from Vittorazi motor if needed.
      Price is £5500 UK pounds plus £450 for parachute.
      Thanks for your inquiry.
      Chris — Wasp Systems
