• The user interface coding for CRS (critical rotational speed) program is done, tested ok, email us for a free copy !

• Heward Microjets informed us that our new 61mm turbine wheel (version 2) for powering WASP H20 has passed the severe tests, which means WASP now has a new strong heart to take off. This wheel is a successful collaboration work between Jetbeetle and Heward Microjets. 
• We made some improvements on both the performance and mechanical strength of the wheel so that the thrust is higher (thrust at max RPM is now 20lbf), and  the wheel is  stronger.

• Jetbeetle's machine shop has been moved to country side called Cishan township,  The environment is less populated so engine testing will be done at there.  Please check Contact page for details ! 

• A small project to build a new compressor of pressure ratio 5.0 is started. 

• Jetbeetle's turbine wheel of 55mm size, has been tested overspeed with success, up to 170,000 rpm it went without fear !
