Thanks for your inext cougar. I have downloaded the manual already, but just may take you up on you offer for the paper copy if I indeed get this plane. Just want to make sure it is an Eagle 2 first. Thank you.

Re: Engine For Goldberg Eagle 2

Been a while since building the first version 63's, but don't believe there was significant difference in design or construction when they updated to the Eagle II.

One mod I made to my second 63 was to run the balsa webbing between the ribs all the way to the tips. Knew that one would take some extra stress and that added only little weight penalty.

What finally killed it was the unsupported Goldenrod running to the elevator control horn. One high speed dive too many and it would not pull out due to deflection of the inner sleeve beyond the fuse structure. As with anything it was a learning experience so guess the term "Trainer" still applied.

The solution I came up with is still used to this day, including the Waco on the build table. I use rods threaded on one end and cut them to length. Often they fit within the inner plastic control rod and when threaded partially in they reinforce and allow for a link to be added to the end. The negative is careful measurement of length is required as little adjustment allowed. They cannot be seen in the pic, but run fully into the fuse on both elevator and rudder runs. Same inside at the servos.

ps. The control setup on the GP Waco is not stock. Their original setup was to use wire all the way through. Thought it inelegant and sloppy. Took a bit of searching to find the right diameter plastic rods that also fit the wire internally.

Sorry to get off topic a bit there.

The LEO is .01 ci smaller than recommended, and the Enya is in the middle. Would anyone here have an opinion either way which would be a better choice for this plane. Or would it be a try and see which is better. And without manuals for each, I do not know what props would be better for either. I am guessing 9 x 6 for the LEO .28, and a 10 x 6 for the Enya? Here's to hoping I can get it soon so I can start training this fall yet on a nitro plane. Thanks.
I have OS .46 in my Eagle 2 and it flies perfect.

Re: Engine For Goldberg Eagle 2

I just flew one with a 4S lipo and an Eflite Power 32 Brushless motor, it worked out fine.

Re: Engine For Goldberg Eagle 2

I've built two eagle 2s. For both I used a .46 sized engine (OS and super tigre). I fly under half throttle most the time with my current Eagle.

Same for me. Half throttle with .46 is what I fly with.
