RE: Showtime
 

Thanks Pat, I did balance it at the tips and will see what it shows at the wing root. Did feel tail heavy especially on final was hard to keep the nose down, like it wants to keep flying.
Thanks Again

RE: Showtime
 

Yeah, I can't believe they never bothered to correct that in the manual!!!! If they didn't make such a fine airplane I'd give them a piece of my mind!

I would start out with it right on the money and go from there. If this is the most advanced plane you've ever flown, maybe a little nose heavy, but I think you'll find it's pretty honest no matter where you are within the CG range.

Oh, some people, including me, have found that while on high elevator rates, (not 3D, but still high rates) when you give the elevator a good pull back, the plane has a tendency to roll. For me it rolls to the right. As long as you're anticipating it, it's not so bad...

RE: Showtime
 

Does sound like your tail heavy.
Generally tail heavy= pitch sensitive. How ever it could be a servo that needs pots(wont center), thrust line issue. I could see this happen if one were to use a 4 channel radio with no expo, no digital trims, and the throw geometry set to Max deflection.
Here's a great link/ reference on trimming an airplane.

[link=http://www.rcaerobats.net/trim_chart.htm]Trim page, scoll down for the simple[/link]


I put the 120 AX on mine it flew great, However I did crash it on the 6th flight with the 120 AX. I took off, made a turn around, did a slow roll about 40' high. Only problem was I was on high rates and I fed it too much down elevator inverted. I tried to recover but failed, not a huge loss. All the equipment survived, the APC 16x8 didnt even break.

I guess the main reason for telling this is, I have parts. I have 2 wings (one has minor damage), wing tube, rudder, landing gear. I also have 2 engine cowls one is hacked the other is NIB. Yes I could fix the plane but I already have too many, and I would like to put the OS in a Fusion 90 some day. Just let me know if anyone needs parts.

RE: Showtime
 

Jacsey If you balanced from the wing tips it should be way off... And she will be very touchy
and tail heavy... I did the same, My 6v started just in frt. of the tail servos for 6 flts. and now
sits under the rear of the wing tube...

Another thing, not sure how your radio and trims are setup, But on my radio I can adjust the
amount of trim movement per each "click"... If yours is the same, maybe the "per click or
fine adjustment" is set to high??? I also use a lot of expo on both rate settings...

Got my S.T. back up, and alls working great:))... Well maybe not my thumbs, but then again
it did not get any worse..... My stock tailwheel bracket snapped at the axe wire connection on
the third flt., guess I may have strained it from my last incident, it has never landed hard...
Anyway I put on a sullivan.... My rudder servo Loves it :-)

RE: Showtime
 

I am looking into getting a showtime, I was thinking about getting the OS 1.20 on it, how easy/hard would it be to do hovers, torque-rolls, harriers, rolling harriers, etc...

Thanks for the help,

Jack

RE: Showtime
 

A profile would be better for your wants.

RE: Showtime
 

He doesn't want a profile, he wants a Showtime. The O.S. 1.20 AX is a very good engine for 3D maneuvers. You would have PLENTY of power. Go for it! Especially since the new version of that engine comes with the option to mount the muffler like a pitts-style. That is a huge bonus, in my opinion, and I think more engine manufacturers should, and probably will, follow suit.

RE: Showtime
 

Thanks for the help P-Diddy. I have a few planes that I want, but just need to decide [>:].

Thanks again,

Jack

RE: Showtime
 

I like the Showtime for 3D and pattern maneuvers over the Funtanas and Funtana X's, based on what I've seen and read.

There are some profiles out there that will do 3D more easily, without a doubt. They're not for me, but if you want to 3D with relative ease, that's probably the way to go.

I like my Showtime a lot, and the BCMA 26cc gas engine pulls it through maneuvers with a lot of authority. I don't use the side force generators very much. It flies great without them and, since I lost one of the thumb screws, they are kind of a pain to install. Not to mention that for some reason I can't seem to make a decent landing with them on and I crunch one almost every time!! (pilot error, not a problem with the plane)

With the CG on the recommendation, you'll find it's a very honest, steady tracking airplane. I was simply amazed how well it could 3D with a fairly stock set-up. I am not using super high-powered servos on anything but the rudder, either, and I have not had any problems or complaints.

RE: Showtime
 

WoW... Thought I put on a better rudder servo than the HS 5645....
With the sullivan tailwheel bracket on instead of the stock setup, steering is right now, I
knew that would change since I stretched my springs and needed to move the rudder about
an inch before the wheel would move, but did not think I'd get so much more rudder action..

RE: Showtime
 

Hi Everyone,
I'm just getting started on my Showtime. I'll be mounting a YS 110 with stock muffler and rudder servo tail mounted. Something just occured to me. I've never had a plane with servos rear mounted. What about all the oil from the exhaust that ends up on the rear fuselage?Are my servos going to get all fouled up and is the oil going to seep into the fuselage and soak into the wood? What do modelers normally do to prevent all this from happening with tail mounted servos?
Thanks,
Mike

RE: Showtime
 

Hey Mike... No expert here... But rear mounted servos has been around a bit... So I
see and have had no problems... The servos are sealed pretty good, so IMO a wipe
down after a day of flying will keep them working for you... As for the bulsa, the firewall
has some protection already and everything else is pretty much sealed up, but with some
of my ARF's I may use "thinned" epoxy and or fuel proof paint to add a bit more. And
around other areas that a small bit of fuel could get into canopy seat area, servo holes/
screw holes I just lightly coat with thin CA.... It's been working for me... I usually
crash em before any fuel problems[:@]..... Also on the firewall and the YS with the
tank at the wimg tube, I epoxy/CA a cover over the firewall tank access hole with a light
piece of ply coated with CA and drill 2/3 slightly smaller holes for the fuel/press. tubing to
get to the engine... And if the tank is to remain in the stcok location, I use silicon to hold
and seal that area and it's still easy to remove... I also add epoxy/CA to stress areas
during the build... Firewall/L.G. areas etc....

RE: Showtime
 

Hello, thanks for the tips. What should I use to thin out my epoxy so I can use it to seal balsa against fuel and oil? Someone told me mineral spirits.
Thanks,
Mike

RE: Showtime
 

Hi to all, I would like to get a showtime question being is that would a saito 180 be too much for the plane? would it mess up the cg? Any info would be great. Thanks

RE: Showtime
 

I read on here that you use denatured alcohol to thin.. I could not tell you how
much or where to get it.... I got some from a fellow club member, and it was a
hit and miss mixture, But I know it was just a small amount to just get the epoxy
to spread a bit eaiser.. You can find info on here if you search(I think) or I'm
sure someone will pipe in... And yes it helps seal the bulsa


viciousfish... I guess its best to keep the planes as light as possible.... That being
said, I use the YS 110 which is about 5oz lighter than the S-180.. and have my
servos in the tail... So IMO you could get the plane balanced without adding weight
by using the pull/pull and moving things forward along with "maybe" adding epoxy
and or beefing up the firewall, but not sure if that would really be needed, but it
couldn't hurt.....

RE: Showtime
 

For thinning epoxy, I use plain old rubbing alcohol.
It just takes a few drops. You can't really screw up the mix ratio, just the thinner it is, the more it soaks into raw wood. A "paint" consistancy is ideal.

RE: Showtime
 

thanks for the info, but wouldn't i need to keep the servos in the tail to help with cg balance? the pull pull system puts them up front right? Does your ys have plenty of power I am at 5500ft and things always seem to be underpowered here. I just thought that the s-180 would be plenty but i want the plane to fly good too. thanks

RE: Showtime
 

viciousfish.... Sorry about that, I had that backwards[:@]... Must B the new Year...
Might have to re- "weigh" that...... I messed up on my initial CG setup, my first 4 flts.
was with my 6v battery just in front of the tail servos, talk about touchy and "hands
off with some up for level invert flt... So if you have the same batt. in that location...
maybe, but I'm not sure if that would be enough to cover that 5 oz without weight...

I'm pretty much at sea level, and for me the 110 is Great, I'm guessing the 180 for
you would be what the 110 is to me here????

RE: Showtime
 

Hi Raideron, warming up the outside of your mixing container with a blow dryer after your epoxy is mixed thins good enough that you can brush it on, but then you only have about 30 sec. until it gums up so that's no good either. I don't have any alcohol on hand at the moment for thinning so I guess I'll try a few drops of the mineral spirits I have on hand. By the way. They forgot to seal my firewall. They just put a line of epoxy up & down R+L side where firewall meets side panel. Otherwise the wood is dry. My Kyosho Oxalys firewall and underside were laquered superbly. Very shiney. People always ask if I did that myself.
Mike

RE: Showtime
 

Hey Mike, Mine looked the same way, and I went with it as is, So far so good after
170+ flts.... And still none of the bad habits has shown itself.... I enjoy flying her,
a bit different than the "D0" but still nice!!!
On my first "thinning" I used rubbing alcohol or thinner that I had(can't remember)
on the bulsa on a 4*60 tank area bottom... It's still together today, but has not been
tested.... Anyway what ever you use, just test it, it's a very little mix, just enough to get
it to spread eaisily....

RE: Showtime
 

Are most people just running standard out of the pkg. motor mounts? I have a Hyde YS 110 size with rubber cushion I want to use.

Can anyone tell me if I can use a header, or flex pipe, or something to get my standard exhaust to exit out of bottom? I'd like to try and keep the oil mess to a minimum and I'd prefer to spend as little as possible. The entire price of the plane set-up was expensive enough.
Mike

RE: Showtime
 

I used the stock mount for the 110 stock muffler.. My vibration seems to me to be low... I
started to go with the hyde mount that I had from my Yak, but I ended up leaving as is.
I planned to use this slimline pitts muffler, but I would have to mod the firewall to get
enough clearence.. Come to think of it the hyde would have giving me the room I needed..
A flex pipe would fit ok and exit as you like as long as you can fit it to the YS... Those
adapters cost a bit.... If your going to add it to the end of the stock muff. mounted correctly
that would work, but not sure about the looks........
The YS does leave a bit of a mess, She does love to be ran on the rich side and it has to go
somewhere:(.... And I screwed both the pipe and muffler as far in as possible to keep the
look as clean as possible with the stock equip. And that added to the mess........

RE: Showtime
 

Raideron, thanks for the reply I think I will give it a try!!!!!!!!

RE: Showtime
 

Just picked the showtime up and have it about half allready. Really nice fit on everything and i am impressed . Going to mount 110 on it using 5645s all the way around.

RE: Showtime
 

Bruce.. That's the same setup I used with a 85?? on the throttle... all with stock equip.
except I used a tetra tk. at the wing tube that I had. All else per the man. Fit was great
I did stretch the tail wheel springs to where the rudder had to move about .5 to 1" before
the tailwheel moved to relieve some of the stock setup pressure... After about 25 or so
flts. my stab started having a little play so I gorilla glued all on with no problems, and my
my tailwheel bracket broke at the tailwheel rod hole, So I installed a Sulivan.. So much
better!!!
I still keep her a bit higher than my other "3D" planes, and have had 2 "fuel out" dead
sticks both in the area of "almost" not making the runway but she just did.. but lucky for
me???? I have yet to have any of the listed problems noted in this thread.....
