Mike Talmadge just posted this weekend that he received the first of the new Egg replacement gearbox cases from the anodizer. I hope he'll have one assembled for testing before the year is out.

Default Empty weights

I polled on the Subenews site and got some replies on RV empty weights with EJ25 four cylinder engines fitted:

1107 IFR equipped but no paint
1167 well equipped complete with paint
1166 on my turbo 6A with heavy paint, steam gauges, 2 full sized AGM lead acid batteries, sound proofing, extra wiring for R&D/ test purposes, roll servo, various patches for airframe mods over the years and a heavy repair on the cowling.

No doubt in my mind that you can easily get below 1100 pounds with a 4 cylinder Subaru, especially using the SPG redrive instead of the M300 or Egg Gen 3 gearbox.

Mike Talmadge has received the new parts and assembled the first of the new re-engineered gearboxes for Egg Subaru packages. This is good news for the Egg Sube engine community as it gives them a new supplier of these critical parts to keep on flying their conversions. Second nice thing is the new box is 8.5 pounds lighter. Kudos to Mike for all this hard work in getting to this point.

On to testing soon.

Can you define "re-engineered" for us? Did a valid Torsional Vibration study occur, and if so with which propeller?

Built an off-plan 9A with too much fuel and too much HP. Should drop dead any minute now.

The original Egg Gen 3 box was reverse engineered and improved in areas where previous problems have been revealed by users.

At this time, no testing has been done and I'm not sure what tests Mike intends to perform outside on running tests on an engine, likely with the common MT 3 blade electric prop.



There does not appear to be any serious TV issues on engines equipped with the dual mass flywheel. Many thousands of flight hours collectively on the Gen 3 boxes now.

Main areas addressed were bearings and lubrication, elimination of the welded shafts and improved splined shaft.

Are we calling this one "Gen 4" or has Mike given it a different moniker?

I haven't heard of Mike giving it a designation yet. Should maybe just call it the Mike box since it's really an all new design with the same mounting footprint as before for retrofit purposes.

Mike uploaded some photos today of the new box.
