Lycoming GO-IGO- GSO-IGSO 480
« on: April 02, 2019, 01:28:56 PM »
I know there has been numerous conversation about the bullet proof Gopher 80. There are still several versions around, but particular to Helio on the 395/295 Super Couriers will be the G1A6/G1D6 and one other with Bendix fuel injection, ala G1F6

I have included some PDF's below to help with overhaul, information, and maybe where to get what you are looking for. Keep in mind that Lycoming sold most of the "geared engine" STC's to Central Cylinder years ago. I'll give an update as to where more info can be applicable to the fleet of Super Couriers.

Beside Helio, Beech with the Model 50 T-Bone, 65, and 80/88 series Queen Airs. Aero Commander used the GO-480/GSO-480's in models 560, 560A, and 560E and 680 with the bathtub nacelles. The "F"model used the IGO-540

Below is the nicest D50E I've seen.

Also keep in mind that the flange shaft versions are not interchangeable to the Super Courier. The Helio is unique in that the hub is the HC B3Z20-1 Spline shaft.

Twin Bonanza's and Aero Commanders use the flanged GO-480's.

Most T-bones flying now also have the McCauley Black Mac prop STC. Something Helio should have inquired about way back in the day.

I don't see any attached PDF files for Lycoming GO-,IGO-,GSO-,IGSO-480 or the IGO-540 whats up?

When I tried to attach PDFs like that I couldn't do it because they were to large and had to put them in the adobe cloud.
then give the link to get them to those that were interested in downloading them.

When it comes to props I am totally convinced that the MT prop is the way to go, sell the Hartzel and go MT to many benefits not to, if the opportunity arises.

Not all Aero Commanders had Flange Hubs. Some had GO-480-G1B6 but they're only running 84" full feathering props. I was thinking about how to use that prop but the controls would be a bit of a problem.   Paul

Blades at 84 inches would definitely put a crunch in thrust and torque@ take-off.

The T-bones have GO-480-G2C6 and G2F6, and as an option with the D50 GSO-480, and the final year 1963 with the J50 IGSO-480.

Some of the T-Bones have 93 inch blades in the Hartzell product, I'm told.

The T-Bone has always intrigued me. If you look at the Type Certificate Data Sheet (5A4), for the 13 models listed there are 13 possible engines ranging from the GO-435-C2 to the IGSO-480-A1B6.
Regardless of which engine it has, it really is a cool airplane.
