kolarshooter,

Yes it did help. I guess I'm looking for something simple and cheap. I just didn't won't to put a whole lot of money into a whole new exhaust system. If the stock exhaust was used and routed out the side of the cowl could you get to everything to tighten it up ? I don't mind the exhaust sticking out the side.



Ya got me there...I played (briefly) with the stock muffler...but I already had the PS muffler set-up on hand and I had planned on using it on this plane. I remember thinking that it would be difficult.

If you ordered a 90 degree adapter, you would be able to set the adapter so it's pointing straight down. Then, you could screw the stock muffler and nipple into that which would have the stock muffler exposed out the BOTTOM of the cowl. You'd be able to sculpt the cowl with a dremmel tool and it would look great. Cheap, and gets the job done! One more thing...the PS mufflers have a different thread than the Saito head, so make sure you order a 90 Deg adapter for a Saito muffler, NOT the PS one. PS carries both, I recon'.

This is a good plane and is fun to fly...I'm sure you'll enjoy it!

Thanks dude. I was looking at the exhaust adaptor for the Saito 82 at Horizon. Sounds like that might work.

I already have the trailing edges aligned, and I too believe that it shouldn't affect flight performance.
I can't wait to maiden it...I have a better radio than my buddy, so this reactor has flaperons ans spoilerons mixing to play with.

Mine came in right at the 6lb. mark with a 2000mAh 5cell pack in the rear most of the hatch area, S3001's on elevators, S3010's on rudder and ailerons, and standard S148 on throttle. Larger, heavy rubber, tailwheel. Magnum XLS-46 with Zinger 11x5 prop turning 13,800 rpm

I'm considering moving the tank to under the C.G. and mounted in foam becausse I am getting faoming of the fuel at certain rpm's.

I noticed something strange about the hinge lines on my right elevator and right aileron.... I have a thread on runryder about the tail issue... could someone please take a look at my post and tell me what you think? I e-mailed great planes and they saw the pictures.. their tech said that it did in fact look like there was something wrong with the elevator. GreatPlanes then told me to cut the tail off the plane and mail it back for inspection to be replaced under warranty... but how am I supposed to cut the elevators and stab off to mail back, then reinstall a replacement?! Are they retarted? If there is indeed a defect with the kit, then shouldn't the WHOLE kit be replaced? It sux because I already have the plane ready to fly and looking beautiful.

Thanks!



Retarded?

They'll send you a complete fuselage, stabs, elevators, rudder, etc. to fix your problem if they are found to be defective. Why not give 'em a chance to come through for you before you proclaim them as retarded.

Some would say it's unrealistic to expect them to send out a new plane without useful evidence of the problem. Most anyone would agree that Great Planes is entitled to see, first hand, what the problems are before sending out a $200 kit. They might use it to enhance their engineering on future arfs (OK, OK quit laughing...I can dream a little, huh?)

If the surfaces are a bit warped, use a heat gun or iron to straighten them out. Mine were a touch off too. No biggie. The most skillfully built planes sometimes need some tweaking.

OK...I just went to your link and checked-out the pics...based upon the fact that your clevises are SO close to the surface, I will assume (which may be dangerous) that you are NOT a pattern flyer (which certainly isn't a bad thing!). I'll go further out on a limb and assume you set up your travel for "all you can get" high rate throws which tells me that your plane would need to be way more bent-up than the pictures show us before you'd have trouble getting the performance you expect.

If you're not familiar with the term "mechanical advantage" regarding linkage geometry and servo resolution, I'd recommend that you just take that baby out and fly her like you stole her. I'm sure you'll really enjoy the plane.

Heck, since it's RTF now, fly the plane...if it doesn't fly properly (in a way which would obviously be attributable to the stabs being a bit off) then call Great Planes and pitch a fit.

I hope my response doesn't sound caustic. I really am trying to help you out.

Good luck with your new "plank" uhm, I mean plane!!!

We're busy...I wrote my response while you wrote this post!

Yup, fly her and see. Sounds like you'll be in for a good time!

Good luck and be safe!

One more thing...I'm no authority on 2 stroke engines (hell, I'm no authority on any engines) but my understanding and experience is that the 2 stroke engines do not have very good fuel draw. You might need to use a regulator or "pump" if you want to move the tank aft (which is not, of itself a bad idea!) Also, you are wise to invent a way to include foam in the installation.

I really enjoy this plane. Hovers well, harriers fine too. I set mine up as an aerobatic practice plane so I didn't make any efforts to get crazy on throws and the like. Since you are talking about spoilerons and the like, I'm guessing you are after more 3D performance from this plane. It has a longer tail moment than...say, a profile plane (and weighs in excess of a pound more than a .46 size profile plane, too)...so it might not be the best choice for a beater 3D plane, but it flys like a "real" plane...and it flys well.

I think you made a good choice on this plane, and I'm sure you'll enjoy it!

Would you mind posting some pics of the engine installation? That seems to be the most "variable" part of the build...I can never get too many new ideas from other modelers.

Thanks!

Yah monnnn!

That's just what I was thinking of! You understood what I (soooo lamely) tried to describe. You're a genius!

I think it might do the trick.

Post a pic when you get it done!!!!

Status: offline 		I'll get some pics up right now...

As for great planes sending a new fuselage or kit, well their tech was only offering a new stabilizer and elevator halves once the old ones were deemed defective.... so how do I magically cut out the old stab to mail back, and then epoxy a new one in? he also suggested to mail the whole airframe back for inspection, but that leaves me out roughly $40 to ship it in a large box insured, and he said nothing about reimbursing me the shipping cost when I asked.

At this point I'm done worrying about the issue with the elevator....

I'm not looking to do har 3D with this plane... just some slow lazy stuff... hovering, spins, harrier.....

If I do move the tank I am installing a perry pump... the VP-30(blue).. I already own several.

And maybe I shouldn't call GP retarted, but all I am getting from them is the generic "sorry for the problem, that's exactly why we have a warranty on all our kits, just send it back for an inspection and exchange." But $40+(out of my pocket) to ship a $160 kit back is throwing away good money.


Is there something I should know about how my elevators are setup? I have the servo rates at 140% and long HD Du-Bro servo arms, with the clevis closest to the control surface as possible for maximum throw.... I'm not concerned about hi-speed flutter on the elevator because I don't plan on flying the plane "fast." and It shouldn't go that fast in forward flight with a .46 motor and 11x4 prop, right?


EDIT:
Oh, and It's a plane not a plank...but you gotta use plank on RR because and plane talk is unacceptable by the heli pilots.
I own several planes, and two nitro powered 3 channel gliders. I love the Norvel .061r/c on the front of my 2M glider... that thing is insane with 20% nitro and an APC 6x3!

Status: offline 		I guess I'll order the Saito 82 today. I've got some APC 14X4W props left over from some profiles I had. I checked and my Graph Tec gear is on the way as well as all the servos and extenions I ordered from Servo City. I need to put the finishing touches on my WH Extra 260 and I'll be ready to start on the Reactor. I guess I had better order that adapter so I can see how the muffler is going to be routed out the bottom of the cowl.

The longer I have had this plane I am pretty sure the Saito would be the better motor. It has been warming up lately here and I can start to see tyhe downsides of owning the OS. Again i would never bash the OS simply because it is well made and runs amazing. But, It just lacks the oomph I was looking for. It is nice to have the extra power and not need it. I think I am going to leave it like this for a little while then save up my pennies for a Saito.

I watched the video of your plane with the OS 70 and even though it flew it well it just didn't seem to have the torque I'm looking for so I opted for the
