Sorry guys, I didn't have the time to scroll through 700 posts to find the answers! I don't want to spend $100+ on JR servos so I'm thinking I'll go with the Hitec's. Which Hitecs do you guys recommend for the Showtime? How does it perform on the Saito 1.00? Will it pull out of hover fairly well? If it is decent I want to go with that. But if it sucks how about the Saito 1.2 or the YS 1.10. Thanks!

Kyle flew with the 645's you cant go wrong there, I would go with 5645's those have more torque plus digital but I dont have Kyle's skill so I need better servos ys110 then 120 then 100, the 100 would hover at 1 half throttle if you use li-ion's lean it out all the way on 30% fuel. and come in at 8.4lbs

YOU HAVE TO USE METAL GEAR SERVOS! i had 9202's on mine and went in to a KE spin and pulled out and the ailorons were fluttering so bad the plane shook. It wrecked the wing but I fixed it. A saito 120 is awesome on this plane. Hovers at 1/3 throttle with 15% and it weighs 8 1/2 pounds. Now im am using 5645 hitecs. This is an awesome plane.

metal or carbonite or composit of some sort would be fine. Dont get the 100 if you can get the 120 but get the 110 first b/c it is just as powerful as the 120 and weighs less so 3d is better, 645's would give great performance for cheap. go with them if you dont have money to blow!

Banche

and li-ion batterys are worth the money from TBM, 2800mah at 7.4 volts with like two cels that are just a little bit bigger than AA and a reg that weighs like an ounce for like under 50$ is the way to go. Fly all day. What was I doing with NIMH.

Do you guys that recommend metal-geared servos have any thoughts about if this is really required on all control-surfaces? Until now I have only seen reports of ailerons fluttering. I am personally using Futaba S9252 on the elevators (nylon-geared), and they have been fine so far. "Knock on wood"! Metal-geared on the rest though.

mike mconville himself recomends metal geared all the way around. beside throttle of corse

pro2k

Thanks guys. I think I will go with the 5645's. Is this plane way over powered with the Saito 120? I mean is it going to be really throttle touchy? I'm definitely not a wild 3d'er. Kind of a combo of pattern/3d.

Pro2k - my F90 with a YS110 was not over powered, throttle was manageable, I believe that the YS120 turning a 17x6 would be lovely on this ship as you are not a 3D nut. If I had my way I would go with the YS140, saw a F90 with one and the flyer was so pleased. The larger prop gave it more wash and helped in hanging her. Alas, I doubt I am going to get another engine for my Show Time.

Can anyone here who has a YS110 in their plane let me know if the plane came up tail heavy or just right ... thanks!

hey guys, I am almost done with mine. here is my setup so far:

Servos: Hitec 5625mg's all the way around and a 5645mg on the rudder in the pul pull position. Futaba 3004 for the throttle but I might swap it out for a Hitec HS81.

For the engine I am still contemplating what to do. That will be my last thing to install before its done. I have a YS110 and a 120 sitting in front of me but the 120 is a bit heavier. Not sure what to put on there but I am leaning towards the 110 to keep the overall weight down.

decisions..decisons..decisions..

I have put on order a YS 110FZ to use on my Showtime, I have a 140FZ too but I think the 110 is more suitable. Kyle advised me also to use the 110 definatelly so he is probably right.

My potential servo selection is as follows:

Elevator: 2 x JR DS8425 MG (same as the 8411 recommended in the manual)
Rudder: 1 x JR DS8425 MG
Ailerons: 2 x HiTec either 5925MG or 5945MG (Please help me here on selection)

I will also use these nice heavy duty alloy control horns by JR, they already have 4-40 holes on them so no drilling is required.

Now regarding the Rx battery seletion, it is the first time I'm going to use digital servos so I don't really know what kind of battery to choose. I have the following options which are high capacity and light at the same time.

-NMP Li-Ion 7.4V 2400 mAh (weight 98gr) + regulator at 5.1V

-Flight Power Li-Po 7.4V (2s 1p) 2500 mAh (weight 118gr) + regulator at 5.1V

What do you think regarding the above Rx batteries? Banche sorry but these are my only options TBM are not available in Europe as far as I'm concerned.

Metal gears are nice --
However -If you never slap the ground hard - plastic gears are better - tighter- longer .
If you run long servo arms and smack down the landings -you should use metal gears.
We run plastic gears on lots of 33% aerobatic stuf but the thumps are what get em - I accidently kicked a rudder -with the radio on and -there went both sets of gears on 8411SA -So I swapped to 8411 gears

Nickolas

Dick,

8411SA is the same as 8411 but with plastic gears right? What kind of battery did you use for the Rx? Is me selection as in previous post correct? Please advise if possible.

How would a YS 91AC handle this plane

pro2k

I have a brand new hs-81 sitting here.....That would be ok on the throttle? I also have an JR 811 digital that I was planning on using but that HS81 is lighter.

pro2k

I don't think you could go wrong with either the li-ons or the lipo's. Both would work great. I think li-po's are bit newer and less stable though. Lipos are more prone to catch fire and explode. But don't let that hold ya back! ;-)

rmh

I use one pack- a 900ma KANN NIMH . (4 ozs)
The plane uses aprox 200 ma per flight -which I replenish using a EFlight Pinnacle Charger - It displays the amps used .
The 9411/SA-exactly same servos except for gears
Instructions do not recommed it -but the 811 servos will also work-
The caveat is that you should back off the throws off the surfaces somewhat .
Personally I have used these servos in very similar setups with no problems whatsoever
I use the LiPos only in my electric planes.

really, 811's will work? I have abunch of those lying around. Maybe I could use those to just get it in the air for now. I wonder what the torque is on an 811 with 6V?

pro2k

Well, I ended up with the Saito 100. What size prop works best for it? I also just bought 3 Hitec 5645MG's. I was going to use them for the elev and rudder and then use 2 - 811's for aileron until I get some more funds to buy 2 more 5645's. Should I use the pull-pull rudder set-up or the other way?

16x4w will work good on the 100.

pro2k

THanks 3dman. Just out of curousity what would you use on the Saito 120?

pro2k

After having put the SHowtime 80% together, there is no way I am going to put 811's on there. The surfaces are just HUGE! Looking good though. Can't wait to get it in the air!

I noticed on this thread that you are flying the Showtime on a Saito 100 with JR 9411 SA servos. I was wondering how this was working out for you as that is the same setup I am planning on. Specifically I'm concerned about the following:

Available power for 3D. For example, can it punch out of a hover? Can it waterfall?

Nylon gear servos. I know they aren't recommended for the Showtime, but I used these on a 28% Staudacher (13.5 lb., 40cc gas) and never even had a stripped gear. The difference however is that that plane was set up striclty for pattern so had short servo arms and overall had very good mechanical advantage. I guess if the nylon gears will be a concern on the Showtime I can install the metal gears but they are pricey.
That's pretty much my concerns. Any additional info you can provide on overall flying capabilities - strengths and weaknesses of this airplane are also most welcome.

Thanks Very much.

I'm pretty sure that Mike McConville recommends the 9411 all around on this plane. That would be the best setup if you plan to have extreme throws with long arms. He designed and built it--he oughtta know what works best.

I've used the 9411 on numerous planes, and have never had a problem with them. Never had a problem with ANY of my JR servos. I've got a 9411 on the rudder of a 40 size 3D plane, and it shows no signs of gear wear or slop after hundreds of flights.

I'm going to buy one of these within the next week. I plan to use a Saito 150 with 9411 on all surfaces. 3121 on the throttle.

Has anyone had prop clearence issues? I got my eye on a 17x5 or an 18x5 prop for the Saito 150.

tIANci

3Dman - what prop are you using and what is your engine taching? Just wanna get some data so I know how it will perform on my YS110. Think mine will be a mix of 5645s (Ele), 645s (Ail), 9402 (Rud) and a GWS mini MG (Thr), shall I throw in some VRs? Hehehe ...
