Dhammer,
I ended up using 4 HiTec HS77 for the ailerons, elevators, and a 5625 on the rudder. Seems to work out well. The Saito 100 is plenty of power. Flies very well. Have not really rung it out yet. The weather has been pretty crappy the past few weekends :devious: Overall, I'm pretty happy with it so far. Harriers seem to have quit abit of wing rock so far. Well see how it does once the weather calms down a bit.

EDMAN,


Thanks for the info on the servos your using. I also was looking at HS77s for ailerons, elevators, and since they are working out well for you, I'll order those. I noticed you went digital on the Rudder. I was looking at the HS645 for the rudder to keep the cost down a bit.

Still not sure what power plant I'm going to be using, but believe I will go with the upper end of the recommended, probably if a 2S the 91FX or if 4S the Saito 91/100. I fly a war bird with a saito 91, and I am very pleased with it's performance. There are quite a few Pilots out at the field using the Saito 100--looks to be a awesome engine.

NOW IF THE WEATHER WOULD COOPERATE.

Thanks EDMAN,

Dhammer,

I think the HS645 will be fine for the rudder, just a bit slower, but you may not even notice the diff. You may also want to check out the new HS-475HB. They are "standards" but have the same torque's HS77. 61 oz at 4.8v. They are a bit slower, at .23 sec. But they're only $17. I was trying to save weight on the tail with the HS77, but later found that I actually could use a little tail weight with the Saito 100 on the nose. The Saito is not all that heavy, 20.8 oz w/ muffler. I like the Razzle so far, seems to be a good flier.

Enjoy,
EdMan

I went with a HS605BB on th rudder. With the 605 I had to use a shim at the rear of the taper because the servo was hitting the other side of the fuse. I also used 4-40 rods instead of the ones supplied.

I have pics from out of the box to maiden flight at the following link.

I used a 5625 on the rudder and it fit fine without having to use a shim for clearance. I also upgraded all control rods and hardware to 4-40. No slope of play!!

In case you missed it.....
 

Awrighty then, Hideho all


The first flight lasted about 3 mins when the horiz stab broke in flight and was left hanging while I fought it back to terra firma..thank gawd there are two elev servos. Damage was minimal, and with one phone call to Horizon, (Shane) the fuse and tail feathers and cowl were shipped here in a few days. (Thanks Horizon)

So, a few days later I'm ready for another maiden...OS 91 Surpass and APC 14X4W...right off the boards straight and true...1 click aileron...talk about honest flyers...man O man...Knife E loops...3 in a row...and whatinthehell is it called when you go to KE, on the 45 up line slam the sticks it the upper left corners and the fuse rotates around the wings...a Pinwheel?
No, it was more like Flip flop round and round on it's AXIS kind of a figuer 8 only stationary..... Did that and it held it's altitude for 10 very long seconds...I always wanted to do that , I just didn't have a plane that was capapable, nor have I seen this manouver before.

Had so much fun I dead sticked (uhh, fuel, stupid) and found out that my CG was spot on as it floated and floated hands off....gotta love it. Flies extreemly light..on the sticks..but nice.
Hover was just a pop up, and bamm, right into a sustained hover...as with others, I need to get some more right thrust to hands off hover...but I didn't mind, it recovers real easy when it falls out of hover...hard to keep it at half throttle to keep it from climing...91 0r 100 4 stroke is a perfect match..Perhaps the Saito 72 would be ideal I'm thinkin'.

Harrier has a wee bit of wing rock, but not much really. I gotta tell you this plane is very well thought out, design wise. KE at 1/2 throttle, both ways and still climbs if you want it to. At $155.00 (list) someones asleep at the wheel or the manafactures are finally giving us exactly what we want in an affordable DO IT ALL
3D plane. Did consecutive rolls while dead sticked all the way to 6 feet off the ground, felt so comfortable. The only miss is I need to get some white on the bottom to differentiate up from down at distance.
As of yesterday it became my favorite plane I've ever had/have.
Gotta have an Ultra Stick (have all three) gotta have a 'Munk in the hangar, and now I need to get a few more of these as back up. I paid $130.00 at the RC expo, and by far is the best value I've ever had. Heck, it's a steal at $155.00 MAP after flying it like I did yesterday.

All control surfaces come installed, hinged and pinned. Canopy and pilot (w/lipstick?) installed. (Pilot swapped for Homer) It has a Extra type fuse, Cap tail feathers and a funfly wing. Again very smart design, best of all worlds IMNSHO. I added a remote glow igniter and fuel dot, and 440 rods, other wise it's box stock. I did the 4 stroke linkage thing but I still need to work on a smoother/less sloppy throttle....

Yesterdays update:


I'm thinkin of swapping the OS 91 for my 72 and tossing the 91 in the WM Chipmunk I have STILL NIB.....I'm almost finished w/ the Giles 3D (4.8 lbs w/ Saito 50) and I need to get the US 120 back up w/ YS 120AC I just picked up in Puyallip...then there is the US 60 that's just begging for the sweet running MDS 68.....Of course I've been putting off the Midwest Super Stearman that's RTF when I get the engine mount for the Tecno power 7 cyl....Ahhh, life is good!

Ok, so today was at the club where I show'd off the Razzle for the first time...I guess I get to name the new maneuver because no one at the club has ever seen it before...KE from L to R on the 45 upline...both sticks in the top right corners and the plane rotates/flips about the fuse and wing, very quickly....and holds alt...thousand one...ect to thou 10 before it sinks.... I outta get commission because I let a couple of guys fly it and their hot footing down to the LHS or Quantum to order theirs tomorrow. Absolutely stunned 'em. Did a KE pass from L to R and at the end went from KE one way up to KE from R to L without a turnaround. Harrier'd it into the wind down the runway at a snails pace...

What a Hoot!
Call Chief AC in Oregon John and see if they'll still sell you for the show price of $139.00...worth a call to find out.


OK, final words...get one.

Hey Mike,
Just curious, were is your CG? The manuever you were talking about sounds like an "Lumcevak". You must have your CG back pretty far. My Razzle doesn't want to do this manuever, or waterfalls. It doesn't want to snap or stall. I would like to know more about your set-up! My KE has alot of rolling and pitch issue. Harriers and elevator has alot of wing rock.

Thanks,
EdMan

EDMAN,

After looking a little closer at the 475's, I belive they will work. I am going to use a 6V Battery so that will increase the torque and also gain a little speed.
Just a little concerned about tail weight. I had removed the covering on the fuselage as I didn't see much glue, so I epoxied the supports real good. I had read a post where someone had maidened theirs and on a landing, which he described as "not hard", the fuselage broke in half. He attributed it to lack of glue. So I did it for peace of mind.

I am going to order the servos in the morning and hopefully in a couple of weeks I can get it in the air :D
Thats with the weather cooperating!!

Thanks again EDMAN

Awrighty then, good question, I forgot that I read about your dilemma before I finished mine.
Turn your fuse over and look at the aft wing saddle where the yellow meets the red....peel the yellow and the red back (don't worry, Ultra coat will iron right back down) exposing the 3 1/3 X 4 1/2 piece of balsa between the saddle and the stick fuse.

Slide your #11 blade under the balsa between the fuse and open it up....now, the bottom of the rear canopy is exposed lay your battery on that shelf...directly under the turtle deck, it will fit perfectly, and there is a lip on the back AND front to keep the battery from sliding back into the fuse. Now, CA two sticks, Popsicle or balsa right on top of the battery, holding it in place PERMANENTLY until you crash or start a cutting. I'm using a 6V batt for faster servo time and much more tork.
CA the bottom back on and iron the covering back where it was...this operation takes exactly 10 mins...Voila, absolutely spot on CG and you cannot tell you were ever there with a #11....takes just a breath of down when inverted.
I'll take a pic when I get home., but when you look at it you'll see..remember the battery is not on the bottom of the fuse, but the top, right under the forward turtle deck, on the provided shelf.

I hope this helps and good luck,
Mike

Mike,
I actually have my Battery pack about in the same location, just didn't butcher up anything. I made a bracket just behind the former were the wing bolts mount to the fuse (on the deck area under the turtle deck). Have you measured your CG? I'm curious of how many inches back from the leading edge you are? Are you using many mixing functions? What engine did you go with? Mine came out a bit nose heavy, so far I have about 3/4 oz. lead in the rear. :(

Thanks for any input,
EdMan

I put my battery right in front of the throttle servo tray, between it and the half bulkhead. I ca'ed a tray of lite ply in to give the battery something flat to sit on and strengthen the bulkhead. I put my Rx on the tray behind the wing hold down. I am using a 1650mAh 6V NiMH. Here are some pics.

Butcher up?
I beg your pardon, (you never promised me a rose garden)
I did NOT butcher anything up! :D
For the record, installed is a OS 91 Surpass on the mount as far back as it would fit.
Can you tell where I cut the balsa bottom in the middle?
No.
When I bashed the US 120 I pulled the Ultra Coat completely off the top of the fuse...unlike Mono, Ultra will go back down several times w/no adverse affects.

Hey Mike,
Didn't mean to imply that you "butchered up" anything. Just a figure of speech............
I would still like to know were your CG is? Did you have to add any lead to the tail? I think I may put a diff tail gear/wheel on it, as I don't really care for the one it came with, make the tail weight I need to add useful at least.

Hideho Ed,
That's why I posted a smiley face..:D
Ok then, so per your request, I measured exactly the cg..as I had not done it, save for a quick finger test at home when I finished.
The CG measured 4 3/4 inches spot on. When I went and looked at the destructions I was surprised when I read the reccomended aft CG was the same, 4 3/4'

At the end of a tank, (dumb no fuel deadstick) the plane was a puttytat to land...slows to a crawl....lands light as a feather....Jeese, here it's a perfect blue sky day and I'm trapped behind my desk @ work...
Thanks Ed, I blame you for making me wish I was flyin' right now...:D

Razzle 3D
 

Thanks for the reply. I think I'm around 4.5" on my CG. Still need to move it back a bit. I was thinking of trying a Menz 15x6, save a little weight from the 15x6 APC I'm curently using, and maybe even a lighter spinner.(I have a 2.5" standard Tru Turn on there now) I just hate adding lead to a plane, but it looks like I may have to anyways. :rolleyes:

Thanks again,

Hey all,

Well I got my Razzle up and flying this weekend. Not sure why it took me so long to many projects I guess.
Anyways the Razzle seemed to perform pretty well. It was the talk of the field Saturday everyone seemed to be impressed.
I went with a 91fx and a 15X6 apc prop. Other than that I did not change a thing. After the first flight I added a couple of washers for some down thrust and that really helped and it was much more enjoyable to fly. I thought I had enough right thrust in it to begin with but looks like I will need to add more. It pulls to the left pretty hard. I think I'm gonna like it even with its colorful color scheme. Later............Ken

About to send money for mine to twister40. I am gonna throw a MDS 78 in it. I think that engine should throw it around pretty good. Will keep yall informed on how it performs.

Razzle 3D
 

Ok friends, heads up.
Now I am on my third set of tail feathers...I have broken the horiz stab in flight TWICE...OK, so mabey I exceeded the design specs...max throw, 100 oz servos...The stab broke in the same place both times...right on the first bay on the LE and at the fuse on the TE.
My fix this time is carbon fiber the top, bottom LE and TE of the horiz stab. You can't do the wires thing as the rudder is too far aft.
My LHS has this very thin 1/4 wide and 4 feet long CFiber that you iron on, and then I'm thinning epoxy and scraping it in.
Horizon has been just great about this, of this you can be certain.
The balsa is just too light, but every time I was able to fly it back down no prob because of the two ele servos.

You also must get some yellow or white on the top or bottom of the wing....really. When your flip floppin' you can't tell up from down without it.

Still, it flys better than anything I have ever flown...better to me....I love a plane that can slow to a crawl....fly backwords...
I did have to snap off the head of the pilot, however. No pilot of mine is wearing lipstick unless it's Patty!

Doesnt sound good :( I am going to have to reinforce mine right off the bat so I do not run into this. Anyone else have a problem with the stablizers?

stab
 

I could see on mine stab was very weak so i knew it would break if i didnt do something,, you are right wires dont work due to horz. and vert. location,, so heres a great way and works great
get a small peice of streamline tubing,, flatten i it out in center which will fit on bottom of fuse in line where you want it on stabs,, you will have to glue a thin peice of ply on botton to screw the tube to. then angle up to stabs,, bend and drill ends and screw to stabs,, what you have is a strut,, solid as a rock and much easier than a wire deal.. and since its not flexible you only need on bottom since verticle is fine,, this is a quick solution and takes only a hour to do.

Re: stab
 

OK, sounds good....can you post a picture please?

Mike

Hey guys
I misplaced my Razzle manual...I think I could finish it with out it , but still would like to have it to follow along......Any owners of the Razzle3D that have an manual and would like to part with it, I would sure appreciate it would be glad to compensate you for your effort, I would also be willing to return it too after I get this one done.....thanks in advance....Gator
