Update on new models

In 2018 LX Aviation was formed to market the 600 kg version of the the well-known Dynamic WT9 into the UK. By far the most popular version in the past has been the ultralight with 17 having been sold into the UK between 2004 and 2011.

But the UK market for microlights (ultralight) requires the UK agent to be approved by the CAA which is a very expensive process and there is no practical way of ensuring a return in investment in the current changing market.  This contrasts to the rest of the EU where such regulations do not exist in the way they do in the UK.

Our new UK Dynamic WT9 demonstrator is the 600 kg EASA LSA version which is certified to EASA CSA-LSA throughout the EASA jurisdiction.  A tow hook and constant speed prop were fitted in September 2019, giving a cruise speed of 125 kts.

The market for 600 kg light aircraft is changing in Europe with countries being allowed by EASA to ‘opt out’ and approve 600 kg aircraft under national regulations.  Germany and the Czech Republic have certification standards for the new 600 kg microlight category and the UK CAA is in consultation with the BMAA, LAA and other interested parties to decide how this new category will be implemented in the UK. The CAA have suggested that the German and Czech Republic certification standards might be recognised in the UK with the LAA managing the approval of factories.  The kit version of the Dynamic will also be available once it is approved by the LAA, followed by the kit version of the 4 seat Advantic WT10.

We will be offering the 600 kg ‘opt out’ version for sale in the UK with a variety of engines and an option for retractable undercarriage.  When this happens we can offer the following options for the new 600 kg microlight Dynamic aircraft:

  • Dynamic WT9 600 kg Rotax 912 with option of CS prop and glider tow hook
  • Dynamic WT9 600 kg Rotax 914 with option of CS prop and glider tow hook
  • Dynamic WT9 600 kg Rotax 912 or 914 with retractable undercarriage
  • Personalised instrumentation on all the above options.

Coming soon:

Advantic WT10 4 seater, Rotax 914 with retractable undercarriage.

The more powerful Rotax 915 will be available as an option in due course
