E5 stretch advice

[Chris Sexton]

That is a excellent set up. Motor and blades will work just fine. Matt has made stretching very easy, in the synergy store is a stretch kit. You want the 626 stretch kit. This will allow you to run blades from 610 to 626.

You can try the 95's but you may prefer the 105's less you increase the tail ratio. Depends on how hard you fly.

Hey Chris,
I bought the 600 stretch kit, not the 626 kit, so does this mean I can go up to 609mm blades?  In other words, I couldn't use the Cyclone 615mm blades but I can use the Rail 606s?  Thanks for confirming what I suspect the answer to be.

I wouldn’t try longer than 606/106. 712mm cumulative total.

The difference in size between the 2 stretch kits is to allow for clearence between the main & tail rotor blades. You do not want the blades to strike each other in flight. Keep in mind the main rotors do flex and it’s possible for them impede the tail rotor. So if you do go with larger tail blades, the 626 stretch kit may be the better option.

I run the 626 stretch kit with 106 tail blades. Stock transmisions ratio. The tail authority is great above 2000 RPM. I fly at 2250 rpm.
I only get 4 minutes with 3700s. 3300s are fun but I only 3:30 and its a little light on a windy day.

IM running the stretch 626 and love it autos much better  then 556 blades, and running the 96 tails but I do have the tail sped up. And works great if you want to try some low head speed stuff with one 6s. Cliff
