My last achievement is to transfer between three eagles as Bing Sven. How do you do it?
The main thing to realise here is that you don't have to catch the next eagle in the air.
First of all, many people think that this is like bat transfer and you can exchange eagles in air ... This is absolutely wrong.
The fact here that if you land from the eagle, you can ski for some distance and ride an eagle again (Just try to avoid animals in the way) and also hitting obstacles when you are skiing doesn't reset the challenge.
Here's the thing: You will have 2 main problems:
First of all: Begin with the Eagle as the starting animal and activate super Eagle then start flying (Hitting obstacles while you fly resets the mission but hitting obstacles while skiing doesn't reset it).
You should fly in air in horizontal level or cloud level. After the lifetime of the Eagle ends you should now have an eagle in front of you and an eagle behind you. Catching the one in front of you is very hard so you should bury your head in the snow several times until the eagle behind you re-appears. Now it's your chance catch him.
Here are some tips for catching:
I have been three hours doing this sh*t and it was my last challenge and finally did it, hope you guys do it too. You won't succeed from the first time. It's just a matter of trial and error. You will restart and restart and restart until you do it. Hoped I helped :)
I followed the directions on this forum post
In summary: To setup turn off super eagle, select Eagle Bluffs, and select the eagle as your starting animal. Then, from the home screen, wait for an eagle to fly by before pressing the ski button. You'll start out with one eagle and then quickly transfer to the second eagle. Getting the third is tricky, hopefully you can catch one after a hill or two. If not, just avoid all other animals until the third eagle. Just keep going back to the start of the game until it works.
