My Roban 700 Apache "Longbow" build

[AtomicFrawg]

Quick question. I'm doing the cascading tail mod and have everything to do the conversion except the tail rotor output shaft. Would you happend to know the length you used or know what output shaft you used?

Thank you

A huge shout out to Dustin Holloman (thisguy65) of Raven Rock Machine who designed and fabricated a sturdy aluminum hinge to allow the stab on my Apache to articulate. If you ever need any CAD or machining services, hit him up. I love the networking that happens on this forum.

Awesome build. I just started mine and I’m looking at doing a couple of your mods as well. One is the beef of up hinge for the horizontal stab. I PM’d thisguy65 over at RCG about purchasing one, but no response. Do you have any pictures of this hinge so maybe I can get an idea of what I need to do to try and make one myself?

really appreciate it
thanks

Can't wait to see the updated Longbow in person soon Steve!

Jetdude, got any more videos of your Apache flying lately?? I really enjoyed your build and tips and all that. Thanks

Thank you sir! Nothing since the last one. The weather and life have not been conducive to flying lately. George is having a Spring fly-in in a few weeks so I am hoping to get some good flights in then.

Thanks, I watch all of you guys doing hella cool stuff!! Great ideas and awesome work here in the forums... and sorry I didn't want to re direct anything from your awesome Apache! I really like your idea of the depron foam and exciters, but I had already purchased these speakers... and was determined to use them. I can't believe there's not a cobra page! I guess I should start one, but I don't really take alot of build pictures.. or do much 'mods'.

I don't to that good with my builds either, but I started a few threads on my builds, it sometimes helps someone who might have questions about a certain part or how a part is installed and a picture can help, I know my builds are not that good because I don't get any responses or anything like these professional builders do, these guys are good and I get alot of info from them. So give it a try and do a Cobra build and pics because I wanted to get that one as well.

This is the route I'm going with my cobra... So far I'm liking it...

Those look like they should work very well.

Steve, do you have details on the tail rotor mod? I've dug around but can't find if you documented that specifically.

Speaking of the X mod, I figured out the direction and the need to pin the tail drive.

I replaced the tail rotor shaft with a hardened 5mm x 100mm shaft I got from Servo City and bought two TRex 600 tail rotor assemblies. I utilized the stock pitch slider and repositioned the balls on it. I also had to get some extra balls and ball links to connect it up but it works great.

It is a mixed bag. The strobes are Strobon V2's from ReadyMadeRC. They kinda have their own controller built in with each light and you just plug them in to a channel on the Rx. The formation lights are powered from a BEC set to 5V and use a Pico Switch to control them off the same channel as the strobes. Finally, the red/green landing lights and instrument panel lights are powered from the same BEC as the formation lights but they are not switche but they do use the light controllers that came with the heli.

[sfcfury]

What light set/controller are you using?

[Hardway]

Great job👍👍😊

Here is the first video of the sound with start up to shut down and a hover. I am calling her basically done. She flies well and looks good. Now to just enjoy flying!

[RCjetdude]

Sound is now in sync with the blades.

Here is a video update on my Apache.

Really nice.

No, the main drive gear and pinion are above the belt gear and motor pinion so it wasn't that big of a deal to change them.
