Hi AHPowelson,

Did you mount your Saito 1.25 inverted or sideways?
I have just received my Saito 1.25 (my 1st Saito) which is going to replace the OS 1.60FX in the ST and I have not decided yet how to mount it. Inverted installations, while nicer, usually give me a hard time.

Also, where did you install your fuel tank? Just behind the firewall or touching the wing tube? I am wondering that if it is against the wingtube the fuel lines may be too long.

Thanks,

Chris

I plan on installing my evo 1.0 on its side and was wondering if anyone has any info as where to put it in relation to the lines on the firewall.

Hi Chris,

The engine is inverted. I've run both my Saito's (1.25 and .82) inverted and have never had any issues with them. I've been extremely impressed with the 1.25! I have the tank mounted in the 'stock' location behind the firewall. Prior to flying it, I was considering moving it back against the wing tube. After flying it, I've found the CG shift from the tank emptying to be neglible in the way the plane reacts. It's not worth it (to me) to make it more difficult than it needs to be by messing with the tank. If I did move it back, I'd use a Cline Regulator (as I've done with the .82).

HTH,

Abram

Hi all... 7-8 months in the box.. Hoping for a "for sure" fix for the "elev. uncontrol"....
Anyway she's pretty much done... won't fly tomorrow, but maybe this weekend... Just
have to remember (just incase) Throttle first and let the YS pull her up)))))))

I also mounted the 125 inverted. Granted havn't run it on the plane yet but, the cowl just covers the whole motor. Real nice! Using the stock exhaust you will have to cut a big hole on the side but it dont look at that half bad. My fuel tank is also near the wing tube with a cline regulator. Ill add pics tomorrow as im just too lazy to go downstairs and take a picture.

Guys,

Thanks for your feedback, so I will go with the inverted install and probably stick with the tank in the stock position for now.

I am not familiar with the "Cline regulator", is it a pump designed for 4 stroke engines? I used a Perry pump with my OS 1.60, it was great; could it be use with the Saito?

Chris

ron you will love this plane

i only hver 4 flights

i need more time before i know if i live it or not

thanks

Hi guys,

Thanks for the answers regarding the CG location, I will fly it this weekend if I don't like it I will move the rudder servo at the tail. The plane is intended mostly for freestyle precision and not hardcore 3D. We'll see anyway...

Here are some photos. My setup is:

-YS 110 with TETRA high pressure tank and APC 16x6 prop
-JR DS 8425 Digital Coreless MG (same as DS 8411 MG) all around and HiTec HS 81MG for throttle
-SmartFly Voltage regulator set at 5.2V
-NMP LiIon pack 2400mAh
-TruTurn Spinner with light backplate
-MK and JR metal heavy duty horns
-JR 10ch Synthesized Dual Conversion Rx

All the above were selected carefully, I hope the plane deserves this setup....[8D]

Rgrds,

Nick

The cline regulator could be found [link=http://www.billsroom.com/pcfs/products/CFS/fuelsysdesc.htm]HERE[/link]. It works with a presurized system like YS engines. The presurized fuel hits the regulator and causes the diaphram to open up to let the fuel in the carb. since it is a presurized you could mount the fuel tank anywhere...


Well Here is my showtime...
Powered by the Saito 125 with cline reg.
4 hitec 5625 and 1 5645 servos
5 cell nobs sanyo HR4/5 FAUP 1950 battery

Well just have to balance, and she'll be ready..... Used all stock setup per the man...
Hoping for the best..... Here's more pics.. just in case..

nickolas: Looks like at 2 1/2 inch arm on your pull pull correct? Did you cross your wires or they are strait through? I put the 2 1/2 airwild horn and I couldn't get the wires working right when they were staight through so i crossed mine.

Hi Rcfury,

The wires are crossed, Mike McConville suggested to cross them. The servo arm for the pull pull is made by JR, very nice quality. I figured out that those arms are very large resutling in massive throws. I have drilled the inner hole and I get around 40-45' degrees in all surfaces, if I used the outer ones I had to reduce the servo travel a lot. Now my travel adjsutment is 150% for all servos except rudder, this gives me 1024 bits of resolution.

Rgrds,

Hi all,

Well after 9&1/2 months my showtime finally got some air under it's wings...
The maiden went well... Two clicks Lt. ail. and down elev and she flew level.. Did not do
much on the maiden, hovered it for about a min. did a K.E. tried a invert flat spin, but it
pull out of it... She's a bit tail heavy I believe... She was very touchy on low rates, 45%
expo... Inverted flt. had a pretty good climb rate hands off.... What do you think???
As best I could I tried to CG at the 7&7/16... Anyway I'm moving my 6v battery up a bit
from just ahead of the tail servos.... The elevator worked as it should :-) That had me
a bit nervous. Landing was easy.... But the YS went sour on me about 25' from the runway
but she came in nice and easy!!.... Ohh... I did try max throw rolls...... WOW... I started to
wonder if the wings (as if I could see them) was going to dislodge itself.. Talk about a roll rate!!

Hi,

I had 3 flights with the Showtime last Sunday. The plane flies pretty well, I still break in my YS-110 and did not perform any hovers or torque rolls. The engine works very well, I did not expect it to be honest. I perfromed some pattern maneures rolling circles and harriers. I had to reduce the aileron throws from 45' to 30' in order the plane to be controllable in rolling harries, the plane feels pretty light in rolling harriers with this throw. Knife edge performance is pretty good, coupling is nearly non-existent. Tomorrow I will probably go through a trimming sequence to see what I can improve, I have the impression that it is tail heavy as in 45' inverted uplines pulls towards the belly.

I want to ask something in this forum: WHAT IS THE DEAD SPOT THAT EVERYONE IS TALKING ABOUT?????? The plane is very predictabe I did not experience any dead spot...that's why asking.

Hopefully this weekend will take some videos and more photos, I'll let you know.

Here some photos with my friend's Adrenaline powered by a YS-110 as well, they are very similar don't you think?

Nick

My thoughts exactly. I never experienced any 'dead spot'. This plane is a rolling harrier machine!

Mine has it. I like the way it flys and think it's a very nice plane. But I don't ever get where I can fully trust it. When it falls out of a hover for instance, it doesn't want to start flying again. I also can make it produce the deadspot on takeoff, if I want to. If you just pull very gentlly back on the elevator it will take off and start climbing. At about 3-4 off the ground it will just stall and fall clear down to the ground. Mine will do it every single time. If I pull just a little harder on the elevator, up she goes very nicely. I also notice a "falling syndrone" when I make an approach on landing. If I'm going down wind pretty slow and make a gentle turn into the wind it will stall and fall a few feet. I also notice it can be very difficult to fly out of an inverted flat spin. Whats to just keep spinning.

I enjoy the plane very much and if you fly it harder with more stick movement I don't even notice. But, it doesn't instill trust. At least not to me. For that reason, I like doing my serious 3D stuff with my Mayhem, UCDs or Velox.

My guess is everybody's Showtime does the same thing. Most are just flying them faster into the landing approaches and are "jamming" the sticks harder. When it's flown this way, no problem. Well, with the possible exception of when it falls out of hover. Another way you can test this is to put the plane on 3D rates (highest rates) and from straight and level pull full elevator. The plane snaps pretty bad in that maneuver as well all though this is different than the gentle stall problem that I see.

Anyways, you wanted to know.

Thanks
Barry

Barry,

I've flown my Showtime in just about every flight envelope, speed, wind, etc.. and haven't experienced any of your issues. Mine will also not snap with too much elevator at any speed (believe me, I've tried). It will, however, snap out of knife edge if I get a little overzealous with the rudder. I don't have any problem with hover recovery or flight spin (inverted and upright) recovery, either. I'm no stranger to unfriendly, snap-happy planes and my Showtime is absolutely not one of them. It's almost too friendly at times. I can't describe any other way than 'easy' to 3D. I was more confident after 3 flights with the Showtime than I have been with just about any other plane I've flown (sans foamies).

Based upon my experience with my Showtime, if yours snaps badly with too much elevator it sounds like a setup issue to me. If it snaps/tip stalls out of a downwind turn, you're too slow! Or, try adding a little opposite rudder to keep the tail up.

Abram

Agreed. Mine is set-up and flown IMAC style (very soft, minimal throws, etc.). IOW, I do not "jam" the sticks or fly it fast. In fact, I make it a point to do a long, smooth, and shallow take-off that looks somewhat scale-like; because the judges are always watching, regardless of whether a manuever is scored or not. Same deal on landing.

And I have yet to see any loss of control or other adverse flight characteristic.

Got a quick question for the guys with Saito 125's out front. Did ya'll end up mounting the rudder servo in the rear of the plane or using the pull-pull? I won't get my motor until next week sometime, but I wanted to go ahead and get everythign finished up, but I just wasn't sure which spot to mount the rudder servo. I was thinking the rear??

i have the saito 125 and mounted the rudder as the pull pull. Seemed to balance pretty good with the battery just behind the rear former. I think it would work as well with the push-pull setup, which will bring your battery up front. Depending how much room you have to use.

I mounted mine with the pull/pull. Was easy to balance. I think I have my battery in the rear of the hatch. I'm using the mighty 110. This plane seems to have a very wide CG envelope though. But after my Funtana experience I wasn't taking any chances. Seems either area works just matters where you put the battery. I love the fact that the plane comes with two choices. Very nice.
Thanks
Barry

LOL Barry, I have got to see the video's of the prop strike, but more importantly of the video of you trying to re-use the prop. Did you re-balance it?

Great job on that prop sewing. It should work out good, shorter blade should get higher RPM.

Sure. It would be foolish not to run a balanced prop. Can't you see the weight?
Thanks
Barry
