Designed by a Pilot for Pilots


We have over 30 years experience with all makes and models rebuilding 2 cycle engines used in the ultralight aircraft.

All engine rebuilds include photos of the condition when shipped in.

We record the serial number tag

We photo the disassembly and all parts replaced with Rotax part

numbers and we photo reassembly phases for your confidence.


You will also get documentation which will further aid you should you

decide to sell your aircraft. 

For the last 21 years we are the only ones in the repair business to do this.
