700size MD500e help

[JohnVH]

Putting a Trex 700l into this fuse, and I am looking for some info on extending the mainshaft, stock is 12x194.1, and as you can see if I space up the mechanics so the blades are close to high enough, the nose wont fit on as itll hit the frame and motor. If I drop the mechanics enough to get the nose to fit, the blade grips hit the top of the doghouse. Anyone else extended a head? I am assuming Ill need the mainshaft, and 3 linkages to the servos, but what about the anti rotatation thing on the back?

thanks!

Personally, I'd just buy some 12mm stock steel and drill the holes where they need to be. I've done this a few times on 500-600 size models and it has worked well. something like this: https://www.amazon.com/Utoolmart-Speed-Steel-Machine-Length/dp/B07YBWMRYD?crid=AIIXNY277C43&dib=eyJ2IjoiMSJ9.JJ-HcpdoN_fFiu8Jp9UMLid_5Iq62I2h9Bc4ndtHn7Ps6gwMNWU9R j4KZILPJGJOdQOKmG-a5wwjfuhO_jsirw9oDIrNi-YpPWoCDcfHmFB-kIvQkNoY9i2mgrzr5HLky9UFfLm5zQ3MtjMZObpned5H-XBKNkjWZz3obFPcUaGWUPM5VN4egiRpqM_zb6J2eGamwq2cQMm sA2IWreAEQIsqihJQqYWQdVaw59c7gh6dQFqLcFd8ySkZrE-D5Oe-h9KxlaOqyqBh5PTm-rDIcHbowu0sxqE8T0O83ty4D3w.awT--rPmbsx-8f0xVMJxTU8TUSDrpqvmx6iOp_Ksf1Q&dib_tag=se&keyword s=12mm%2Bshaft&qid=1730313067&s=industrial&sprefix =12mm%2Bsfat%2Cindustrial%2C185&sr=1-21&th=1.

And then one of these to take the place of the mid-shaft collar: https://www.ebay.com/itm/355756540275?chn=ps&com_cvv=8fb3d522dc163aeadb66e0 8cd7450cbbdddc64c6cf2e8891f6d48747c6d56d2c.

You could go with one of the hardened steel shafts as well, but it would be much more difficult to drill the holes.

So I installed a head off a 700e v2, and longer mainshaft, that cured this problem, ofcourse I didnt find the solution until I bought another whole 700 heli. haha!
