RE: eagle 50 helicopter
My advise go back to your local hobby store & buy a Align Trex 450. Excellent flying heli parts available everywhere bit more expensive but,, if you start to concider what it cost you for postage & handleing plus the time and aggravation to find the parts you need it balances out it the end. I bought, recieved a Raptor G2 for christmas purchased through X-Heli. They ran out of partts shortlty there after & I had to search High & low tof find what I needed, with my search ending in China with Walkera which is what the Raptor g2 is A Walkera 36B.
I also tried getting hop up parts through X-heli & found the technical customer support sadly lacking. Sent me batteries that where listed as upgrades that just did not fit on the bird.
So, that's my advise & my story good luck hope you get it worked out. Do not give up on Heli's they are great & its a great hobby when you buy quality products.
