Thats the only thing wrong, should bemuch more than twice :D:D

RE: Showtime
 

I would take out the Hitec HS605's-aren't they really old?? I used them 10 years ago on a Goldberg Sukhoi, the centering is poor and they are only 77oz. torque with slow response. I would at least upgrade to the new HS635 Karbonites on elev halves and HS5625 on ail&rudd-thats what I,m using on my ST,might get it out this Sunday for its maiden-getting pretty excited after Barrys post. (got the HS5625 for $50 each from Tower with the discounts)Love the sound of the Digi's!!!

RE: Showtime
 

Hey Barry,
SPUD here. Well I have a ST now. Just finnishing it up. I put my OS 120 4C in the nose, 635's ail & ele, 645 on the rud, and a 3004 on the thro. Waiting on my spinner to come in to mount the 16-4 APC. Went with 3" wheels I fly from grass as well. This thing goes together quick. You've used 645's in the past, have you ever had one sit there and glitch? I changed recievers and it still sits there bouncing back and forth. Real slight movement but still there. Will this go away ounce the servo wears in a little? or is it a bad servo. This is my first MG servo. It does stop after a couple seconds. Should I be concerned? Someone with some expertise chime in please.
I've read the whole thread . Has anyone done anything about the slack in the pull-pull? Or do we all live with it?
Raideron, Get that thing together. It builds quick. I'm with Barry though on getting your DO back together.
I don't think my spinner will be here in time for Sunday, so I guess I'll go and charge my UCD for tomarrow.


SPUDs out...............see ya!!!!!!

RE: Showtime
 

:)Spud, How ya doing? Good to see ya with a Showtime. Word of caution, this plane doesn't recover from stunts as easy as the UCD. You have to fly it out of them. And it won't flat spin like the UCD but it flys other things way better. Just be careful with your early flights and get the feel of it. You'll really like the plane but it "feels" different. I had to get used to it.

My 645 have been rock steady since day one and I've had quite a few of them. I use 4.8v. I've heard some complain about 6v having the "jitters" when you first start with a fully charged battery. But as soon as you use them a few minutes they behave themselves. Maybe just let your battery dump just a bit and they'll be fine.

My rudder is very precise and I like the pull/pull. My wires are not super tight either. But I can take slack out of them with the clevis if I need to. Just snug them up a bit and go fly.

My guess is you'll really like this plane.

Thanks
Barry

RE: Showtime
 

Hey Barry,
I liked it the minute I opened the box. I worked on the pull sys & made a control arm with the 1/4" differance. Now no slop on the non-pull side. I think I remember you saying something about 6V on the UCD thread & the 645s. I was going to use a 2000mah 4.8V but I couldn't get it loose from my Sukhoi. I have it gorilla snotted in. The UCD is all charged up for the morning. As soon as I get the spinner in, I'll be able to finnish my Showtime up.


SPUDs out............see ya!!!!!!!

RE: Showtime
 

Some quick questions about the Showtime with a Saito 100

1. Nose heavy or Tail heavy? Where is the rudder servo?
2. Which prop are you using?

Sorry if this is on the forum already, but I sifted through 36 pages and did not see it. I thought this would be faster.
Thanks for any info on this.

Scott

RE: Showtime
 

:)jetmech51...
With the Saito 100 you'll want to use the pull/pull system which means the rudder servo is in the middle of the fuse. I did that even with the YS 110 which is about 7 ozs heavier than the Saito. You'll want to mount your battery forward.
With the Saito I think the best prop is the 16x4W but others think the 15x6. Either way should be fine.
Thanks
Barry

RE: Showtime
 

I came up with a little mod for the Showtime, I was kinda tired of having to take the canopy hatch off to assemble the dang thing. So I ditched the nylon bolts and and installed hard points in the top of the wing for screws to hold the wings on. I figgured that the ST is constructed so much like a 40%'er any way, may as well make it a little less of a PITA to get together at the feild. Pretty easy mod too.
It seems the ST must have a huge balance range, I have a Saito 100 on mine and 3 servos in the tail. I started out with the 5c 1650mah pack over the (close to) the gear mount and ended up moving it back to just in front of the servo tray.
One thing is fer sure, I really like this plane a bunch! A great knock around plane that looks and flys fantastic and is great for those evenings when I dont have time to drag the 38%'r out.

ME

Oh, I did another mod too, I cut the sfg's down to the first brace parallel with the top, they are still very effective, but much less prone to getting broken in taller grass, rough runways, and transport.

RE: Showtime
 

Can you post pics on those mods? What servos are you using in the tail?

RE: Showtime
 

Got a question for everyone Im working on a wish list for this plane and am still somewhat new to the ins and outs of stuff so was wondering in the JR line of servos what would be something a little cheaper for the Ailerons and Elevator servos or is it a must to put the $400 dollars worth of servos in this? Thanks for all the help!

Chris

RE: Showtime
 

I put JR 125MG Sport on mine, and I couldn't be happier. Fast response, excellent centering, and CHEAP... (well, at least for a high torque servo with metal gears). 35 dollars for 125 Oz/in torque at 4.8, and more at 6.0V.

RE: Showtime
 

Thank You Josh I wondered if the JR Sport line was any good still being new to the market Ill have too look into them maybe. We were having this discussion at the field yesterday too and someone else suggested maybe using something more around 50oz at the 4.8 v and just using a 6 v battery to boost the throw and speed just being somewhat not knowing all the ends and outs of servos yet thought id pose this question to everyone here. I know i want to stay with JR servos just thought I might be able to use something a little more cost effective for the wallet.

RE: Showtime
 

ANOTHER ST MAIDEN FLIGHT, HERES THE SETUPS:
MOKI 135 W/CLINE SYSTEM
5 CELL 2100 MAH NIMH BALANCED @7 1/2" AT REAR OF CANOPY AREA.
HS 5625'S ON AIL&RUDDER,HS635 EACH ELEV.(USING PULL-PULL RUDD)HS81 MG ON THROTTLE
USING ALL STOCK ACCESSORIES:AUW=9.9 LBS(FAT*****)
FLIGHT REPORT: HAD 7 FLIGHTS IN 10-20 WINDS,6 DEAD STICKS-MOKI PROBLEMS, DID GET 2 12MIN FLIGHTS, ENOUGH TO GET A FEEL FOR THIS PLANE WITH AND WITHOUT SFG'S.
DIDN'T NOTICE THE EXTRA WEIGHT,FELT LIGHT,WITH 6 DEAD STICKS INTO THE WIND AND DOWNWIND, NOT A PROBLEM,IT SHOWS NO TENDANCY TO TIP STALL, LOOKS LIKE A PATTERN SHIP LANDING.IT NEEDS A LITTLE MORE RIGHT THRUST(DIDNT ADD ANY WHEN BUILDING)BUT IT STILL HOVERED & COULD GO VERTICLE STRAIGHT UP WITH A LITTLE RUDDER,ALWAYS FELT I HAD CONTROL REGARDLESS OF THE THRUST LINE. FLYS NICE PATTERN LIKE STRAIGHT LINES,POINT ROLLS NICE.KE EASY WITH NO COUPLING W/O SFG'S.WITH THE SFG'S IT DIDNT HOLD KE AS WELL AT HIGHER THROTTLE, NOT SURE WHY. BUT HA KE SLOW FLIGHT IS GREAT, DOES THIS LIKE A LARGE U-CAN-DO(I HATE TO COMPARE ST TO U-CAN-DO) BUT THAT CRAPPY BUILT PLANE DOES THIS WELL-BETTER THAN MOST.THIS IS THE BEST PART: ELEVATORS & HARRIERS ARE AWESOME, EVEN IN A WIND NO ROCKING WITH SOME SPOILERONS, ST CAN HOLD VARIOUS AOA IN A HARRIER,FROM 45 DEG. UP TO 60DEG. AND ELEVATORS CAN COME ALMOST STRAIGHT DOWN(NOT QUITE BUT STILL DROPS LIKE A BRICK-SO COOL). I TRIED A FLAT SPIN OR TWO,NOT COMPLETELY FLAT,SINCE I DIDNT TEST THE ELEVATOR DURING INVERTED FLIGHT I DONT KNOW YET HOW THE CG WILL GO.
THE FLAT SPINS WERE KIND OF SLOW,LOOKED LIKE A LARGER PLANE.
OVER ALL THIS MIGHT BE THE BEST COMBINED FLIGHT CHARACTERISTICS OF ANYTHING OUT THERE OF THIS SIZE. I HAD THE 68" YAK WITH ME, READY TO GO BUT I NEVER FLEW IT, I THINK I LIKED THE ST BETTER, EVEN WITH ENGINE PROBLEMS I DIDNT STOP FLYING IT UNTIL THE SUN SET!!!!!

RE: Showtime
 

:)mixmaster
Man your Showtime does seem heavy, mine weighed 8lbs 12ozs with the YS110. Maybe just your engine is heavier. Anyways, sounds like you like yours, I certainly do mine. You'll like it even better when you get the engine running right. I had engine trouble with mine at the start also. But last Saturday I was doing some great high allitude blenders with zero throttle until about 20-30 off the ground and then hit the throttle hard and it would just fly out great. What fun and impressive to watch. I love my Showtime.

You felt bad about comparing the Showtime to the UCD? Man, I make that comparison all the time. I love the UCDs too. I have the 60 size and the 46. They are my favorite airplanes. Some people give them a bad rap, mostly, I think, because they are not a precision flying airplane. But for 3D and all around fun, they can't be beat. That's what's important to me. Having fun. The UCDs do that as well as any airplane out there. No reason to no want to compare the Showtime to them.

I can get my Showtime to flat spin (pinwheel) with the SFGs but not without them. The flat spins without the SFGs are nice and flat but a little slower and drop fairly fast. Mine does still have wing rock in harrier and elevators. I think the feeling is the heavier engine on the nose helps this. I can do them but have a fair amount of wing rock even with a little spoileron. The other thing I can't get my ST to do is a rising flat spin. But my UCD will do it....Go figure.

My Showtime does show some kind of weird behavior right at take off. When I'm trying a gentle slowly rising take off the plane lifts off than falls right out of the air, the wheels hit (if I let it fall that far) and then bounces right back up and I go flyinng. I also notice this in turns from into the wind to downwind. If I'm not careful there is a "dead" spot where the plane just loses lift. If I make the turn fast or compensate I hardly notice it, but it's there. I think the wings at certain angles block the wind to the elevators and you lose that elevator authority. Kinda weird. I've noticed it several times. Anybody else notice this problem or have any ideas what causes it. At the risk of comparing the ST to the UCD again...My UCD has never done anything strange like that. Anyways, anybody had the problem or have any ideas what it might be. Pretty small issue really and I love the plane, just curious what it might be.
Thanks
Barry

RE: Showtime
 

I'll jump in here.......I've felt the same thing. I first thought that I got it too slow on the turn to final and it started to stall, but couldn't be sure till I did it later in the day again. There was a dead spot where the controls felt super mushy, then before I knew it everything felt normal. I still can't explain it. I just started making my downwind and turn to final a little faster. I'll admit I haven't flown it much lately, my H9 Sukhoi that I just aquired is getting the most of my attention. But I have also felt the same as you described.

RE: Showtime
 

What is the right size spinner for the Showtime?'
thanks

RE: Showtime
 

2.5 IN

RE: Showtime
 

At the risk of being blasted by all you Glow Engine guys, I will make mine powered by a 4130/20 AXI electric!

My ST will be here by weeks end, so I am still collecting all the components I need.

After scanning 35 pages of kudos and reading this months FLY RC Mag....I can hardly wait!!!

My thanks to YNOT for a great video!!!

Magoo

RE: Showtime
 

Larry ... you going 6S? I think it will be fun with that power plant but for total mayhem then I guess the 5320 might be very cool. You seen the Fliton Extra 330 video with the AXI 4120? Its got so much power ... the Fliton is about only 6.25 lbs with a SA82. Anyways, its always more fun to fly electric, eventhough I love glo ... the EP torque and power:weight ratio is always much better. Just that its costly ... I am sure your ST will be great fun, please put the video up here.

RE: Showtime
 

Does this month's Fly RC magazine have a review of the ST?

RE: Showtime
 

yup

RE: Showtime
 

What are you going to use for battery?

RE: Showtime
 

Fly RC Sept or Oct issue?

I can not see anything in October's issue:

http://www.flyrc.com/current.shtml

By the way Magoo have you seen Kyle's video with Showtime??:D Here it is:

http://www.dodvideos.com/Kyleshowtime_smaller.wmv

RE: Showtime
 

The trick with AXI motors is to use high voltage/high windings. I will run a 10s Kokam 3200 @ 20C discharge. 37 volts will produce enough poop for that 4130 at 8-9 lbs easily. My brother flys his 11-12lb Hangar 9 Corsair with a 4130 and it flys wonderfully.

I do have a 5320 but I'm saving that for my 12-13lbs Sukoi SU-31. That will require a 2p version of above.

That article in FLY RC mag has the Showtime on the cover!!

Thanks again fellas!!

Magoo

RE: Showtime
 

I dont like to compare them because of the difference in construction methods,the UCD is crude compared to ST. But I do miss it , you get used to that slow /stable flight, when you switch planes, you really notice the difference. However, I think the ST will help me forget the UCD. The only weird thing I noticed(and forgot to mention) with the ST is it flys nose high some times,like its too tail heavy, but when I throttle down it drops right away and with the nose down. It lands normal too. I need to fly it again to check inverted flight&elevator required to level it. I wonder if that is what you are seeing? Last night I checked a few things on the engine&fuel tank, all looks OK so I swapped out the Cline regulator and check valve, the check valve I was using lets a lot more air thru it than the others, wonder if it was loosing too much crank case pressure,not sure what crank case pressure does? I hope that does it, I need more S H O W T I M E!!! (where is your cg at?)
