My Roban 700 Apache "Longbow" build

This was from the TIA Fall Fly-in as well.

Yes, they do look much better !

I had an issue with my main wheels turning out so I modded the main struts by cutting them just below the lowest rib and drilling them to accept a piece of 5/32" piano wire. M3 grub screws secured against flats on the pins straightened the wheels which I also changed to 2.75" Robarts. They look so much better.

Wesley and Lori Miller of the Merry Boozers RC Channel shot some good video of the Apache flying at Nall in the Fall. Very nice.

Awesome, Looks great seeing it in the air with the radome! Curious as to what the modifications to the main gear hub were to make it work.

Complete re-machine of the hub to get rid of the compression slot basically.

Been enjoying flying the Apache this weekend at the TiredIron Fall Fly-in. The new fixed Radome/hollow main shaft mod is working great. It is flying really well right now.

Finished the hollow main shaft/fixed radome mod on my Apache. Took some doing but with the expert help of my friend Darrell Sprayberry we got 'er done. He is one of the most skilled builders I have ever seen. A self taught machinist he also works with fiberglass molds and can basically make anything. The "Longbow" is something I have wanted for as long as I can remember.

excellent ! Really looks great in the air ! Nice scale flight.

Very nice! (two thumbs up)

Got flight #4 in today after spending some time working on the tracking. Only the slightest vibration exists now in the bottom Hellfires which are only loosly attached. I think I can easily fix that. Anyway, this bird continues to impress and I am getting more comfortable at the sticks. I now have a hollow main shaft and will be working on a fixed Radome mod. Still need to decide what markings and details I want to add prior to weathering it up.

Superb - really does look the part, both on the ground and in the air. Congratulations on a fantastic outcome

Ok, after a failed first attempt, things went better. We learned some things along the way. If you recall I reversed the direction of tail rotor rotation. As a result, we discovered on initial spool up that the tail rotor suddenly stopped spinning so back to the bench. What we discovered was that the short torque tube has ends that are threaded on with LH threads which now loosened with the reversed rotation. After some epoxy was used to glue the ends on we were back in business and here is video of the latter half of a 5 minute flight. I used two Roaring Top 6250 35C packs in it secured to a battery tray that I added. There was just enough room to fit the cockpit tub but I could not push the batteries all the way forward so I ended up having to add 1.3 lbs of nose weight to it. Needless to say I think we got the CG pretty close based on it's flight characteristics. Here is video proof that for as heavy as this bird is, she flies and flies well. Big thanks to Craig Quillen, our TIA resident heli guy for his help to get it setup and flying.

Good job, excellent flight and it looks very stable, looks awesome, can't wait to get my 500 in the air now.
