Yes, avoiding the need to cut a hole in the gear cover looks like the main installation issue . I suppose the motor could be mounted sideways with some bevel gears in the drive but it's very messy. Had you thought of putting the drive at the other end, e.g. with the motor behind the bed and a belt drive to the lead screw?

Thanks for your replies, saves a bit of money compared with doing it yourself direct with the States.

Is anyone else planning to fit ELS to a Myford S7?

I'm trying to avoid the double whammy of exorbitant shipping from the USA and the import charges. Has anyone found a source for the TI board in the UK or elsewhere in EU?

I would council against boring the case from both sides because the alignment of the crankpin with the rotor pin depends on having a straight hole with truly parallel faces back and front. The castings leave a lot to be desired that's for sure. Roy

Apologies for slightly re-purposing this thread but it seems appropriate given its title, where can I get hold of Nalon Viper plans? I feel that I should be able to locate them but searching has come up with nothing. I know they were sold by Motor Boys but not sure where they went after Ron Chernich left us. Thanks in advance, Roy

Correction: The ML Midge is a Mark Lubbock design.

Cox engines were made on very advanced machinery (for the time) and would be very difficult to reproduce at home. Not just the fits and finishes but the plastic intake housing. A much more certain bet would be one of Chris Boll's designs. My first motor was his ML Midge of 0.8cc. The BollAero at 1.8cc would be even better. The most critical factor in getting these small diesels to run is the piston-liner fit. Both components must be separately lapped to the correct fit. Expect to need several goes, i.e. pistons, the first time you do it! The modelenginenews.org site is the best source for techniques.

I see I'm not the only one frustrated by this rule. I have what someone wants but no way to tell them; maybe this posting will unlock the gate?

Yes, the Model Aero Engine Encyclopedia by Ron Moulton. Out of print but available secondhand (at a price). There is much information on construction on the late Ron Chernich's web site:
