I'll let a cat out of the bag here. Techwell is the manufacturer who is suppose to produce the Richey/RD engine. We have been working with them for over a year now and they just can't seem to get it together on production. They are over committed on another project. All the specs and testing for the engine has been done with great success but it is a FAR CRY FROM THEIR STOCK MOTOR. This is the reason there are no motors available yet. We are looking at other ALTERNATIVES/MANUFACTURERS because of this reason. By no means have we seperated from them yet, time will tell as they have all the specs to produce the engine and I have been running a single prototype Richey/RD version for a while with great success.
