set ups for a Skyray 35 and a full fuse Oriental????????
« on: June 12, 2014, 10:58:36 AM »
I've done a search in "List your Set-ups" and couldn't find one for the Skyray 35 and the full fuse Oriental. 

Questions:
Would the set up be the same for the Brodak ARF Oriental work? I didn't know if the Brodak ARF was profile or full fuse.

Has anyone built an E-Skyray 35?  What set up did you use? What would your use?

I'm going to scratch build the Skyray, would you use Brett's mods on the E-Skyray? Or other mods since it's going to have E-power?

Thanks for the help in advance.

Just copy similar sized planes for example a flite Streak or a ringmaster.

I should have thought of that. I'll look at those planes for the engine size.  Now on to the Skyray mods?

I'm not sure what all mods Brett recommends, but I'd do all of them plus adjustable leadouts -- because particularly with an electric, you may end up moving the center of gravity.

The only things that I would do to a Skyray are:

  • Two wheels instead of one
  • Move the CG forward (maybe -- I didn't touch mine)
  • Adjustable tip weight box
  • Adjustable leadouts
  • And, of course, build three, use balsa ribs, and maybe use two stub ribs per real rib instead of one (i.e., decrease the spacing)

Aside from that, build it and fly the heck out of it.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Thanks Tim.
I had planned to add those features, the mods I wondered about were all balsa full size ribs (no half ribs),  if I should lengthen the fuse (seems some do that when going e-powered), and adding fixed flaps.

I think the extra half-ribs vs. full ribs thing is a matter of personal taste, ditto the fixed flaps.

I don't know about lengthening the fuselage -- I suspect that the advantage gained will be slight.

I know that I loved my nearly-stock Skyray, and heartily recommend it for the beginner -- if I were going to teach a stunt camp for beginners, that's the airplane I'd hand out when you walked onto the field.

I think the lengths are right on the mark straight out of the box, and that's why it's such a highly regarded stunt trainer. I know I've done well with mine, an old one given to me by Ray Copeland. Built Brett style plus fixed flaps. I'm pretty much copying it with my new Skyray that's on the table now, and it will serve to tune my full pattern flying now that I've been booted up the food chain. I'm still flying IC though. Addicted to fuel.

Duke, speaking of the Oriental, I have an ARF in the box next in line after the Ray. Full fuse, and all I know that's different from the kit is that it has a 4" bellcrank, whereas the kit has a 3" crank.

Hey Rusty, good to hear from you.  You prompted me to look into the Skyray 35, and My son has two of them (one from Tim).  How much room do you have between the back plate and the LE of the wing?  I'm trying to figure out if I have enough room for the battery.

I seem to also be addicted to castor oil, but if I didn't have room for the battery behind the motor I'd seriously consider putting the battery on the inside, or underneath the motor in a chin cowling.

When you said "lengthen the fuse" I assumed that you meant lengthen the tail -- lengthening the front of the fuselage shouldn't create big difficulties, unless it throws your balance off.

I just came in from epoxying the doublers on the new Ray. When I go to check on the glue, I'll measure the nose on the old Glueray, AKA the Ray Ray.

when looking at electrics you MUST keep in mind the vertical CG,, the battery is a heavy lump of weight, and putting it anywhere but centered on the wing centerline ( vertically) could cause some issues with trim by throwing the vertical CG off..

as another thing to think about, I try to mount my battery at least on the centerline of the fuse or outboard to help with tip weight,,

Four inches Duke. That's from the backplate to the LE.

Good points.  I've seen a picture of someone's plane with the battery underneath, and it looked good.  I don't know if they moved the engine up to compensate.

One could mount the motor and ESC on the inside, and put the battery on the outside.  That would change the thrust line by half an inch; dunno if it'd be a problem.

Maybe we should just encourage Duke to go ahead and lengthen the fuselage, because if it ends up nose heavy it won't be OUR effort to whack it off and make everything fit!

Mark Weiss built several e-Skyrays for Joe Nall last month. He might have some advice for y'all. I know he wasn't happy with them at first, but if you ask him, he probably can tell you some things to watch out for.

Here's his SH profile and contact info if you want to contact him:

Thanks Rusty.  I PM'ed Mark.  I posted last night, but it's gone now.  I've lost posts before, I don't know where they go.  Anyway, I looked at the boy's Skyrays last night and I might be a little short on room for a battery, at least the ones I've been looking at.  I looked at my Bob Hunt/Pete Peterson Holeshot and it might be easier to convert to e-power.  I'd like to built a simple plane, easy to repair, and easy to make an e-plane. The Skyray and the Holeshot seem to meet this. The Holeshot has more room and looks way better. My desire is to start learning the pattern with this setup.

Looks like he rarely checks in here, but his e-mail address is on that page too.

Here's an Idea, and this is a similar plane, a Lightening Streak. A pocket in the wing.

I've talked to a few people about that before.  I just don't like the sound of cutting the LE.
