G'day All, Thanks so much for the welcome, RF has alot of brain power on tap ! Thanks for the likes and the warm welcome, most appreciated. I struck the site after researching the little old 2 stroke " Skylark" Motor simply because I unearthed some paperwork relating to it in a carton of other rotax parts I recently acquired, which included a late 70's manual called " Proper care and Feeding of the Rotax". Got laugh out of that. I found a service manual, advertising material, information sheet- brochure etc, There s also a bit of correspondence with Ron Lang who designed and built this little solution. I'll scan and publish this stuff and maybe send the originals the Melb. Aviation Museum. While the motor looks like a contraption of mower parts, it seems that there maybe more to it. Seems Ron Lang was / is ( anyone know whereabouts's these day's ? ) a design engineer that raced Motor bikes in Auss and Europe. Nice little piece of history anyway - I'll get the info onto here and you blokes be the judge. Thanks Heaps oneTrack for the tip about the generator, I hadn't really thought about that, A series Hybrid config is the way that the Auto industry is favouring, so I'll dig through my pile of motors and stuff. I spent a while with OPE, Outdoor Power Equipment under Australia best Master service tech. so I might already have something leftover that I can start looking at straight away. Any one having issues with their motor just drop me a line - I might know something their. I'll be off work for a little while soon so I will have a chance to publish info on what I have engines & motors wise, at least for the testing phase and I will put some info here on the Topology options for the motor drive / engine / redrive with combiner and electrics, as i see it. I'm no engineer though. The topology will be more of a Weightology, induction motor would be great but heavy - that's what experiments are for !

G'day Westie, Thanks for the welcome. Specifics are a little fluffy at this stage but the aim really is to come-up with a Combustion Engine- Electric & drive unit that reduces the cont. load on the prime mover and provide a backup power source should the prime mover quit. It's in the U/L <30HP range. It's not hard to make such a setup with off-the-shelf parts but I'm aiming to use commonly available parts to reduce up-front an replacement/ ongoing costs. The electric motor is AC for efficiency, will likely employ a VFD at the right price. Currently I have a couple of Electric motors and a Couple of 2 & 4 stoke Engines and an adjustable pitch prop. Just need to setup a rig to interchange combinations and start pulling results. Electric motor produces solid and cont. torque. But electric systems are heavy and costly so it will be a case of experimenting. The instrumentation for capturing performance will cost a few buck$. I have crunched a fair few numbers and a Parallel Hybrid drive with Regen for , preferrable Ni-CAd battery ( I have worked with Li-ion alot =( ) looks very modular and scalable on paper. Ultimate prize for me is low cost and maximum amount of Aussie made parts. I'm sitting on a few gems in that sense.Any input appreciated.

Hi All, My name is Brad Bell, just joined. Please allow me to introduce myself. I work for Microair Avionics / Digecor PTY/LTD, In Bundaberg ( Next door to Jabiru ) and Brisbane. Looks like just the forum for me. I hope that I have knowledge to contribute, I worked in Small Engines and Electric Vehicle Technology ( Tritium PTY LTD ) previously . My work role is : International Logistics Officer Production Close Support Officer R&D close Support Officer I am the Manager also for our Warehouse under CASA Part 145 & PMA , EASA And FAA regulated PMA. Worked closely with MRO's and DOA's like Comtech Aviation in Sydney. My Project is to build a Hybrid powerplant for an ultralight I gained my pilot's licence in the AIRTC in the late 90's but have been grounded since due to , life I suppose. Hope to change that with a Mitchell Wing build.. If you know anyone that needs help with anything I know, drop me a line
