Servo Tray for Hitec DS5xxx servos?
Looking to mount a 5945 or 5975 for an aileron servo and would like to mount it sideways, it'd be a whole lot easier (I think) if I could use a tray. Hitec doesn't make any for these servos, would the futaba or airtronics trays work?

High-speed needle 'external pin', where to buy?
I have a Saito .91 and have seen people with high-speed needle valves that have a bent pin coming out of the top that you can poke out of a cowl for adjustment, do they exist for the Saito .91 or how can I modify mine? Thanks, Sam

RE: Argh, I hate my Saito .91, what gives?
Warpd, you want the APC 15x4W which I'm running 2k-about 9k but I should be able to push into the lower 9k I think.

RE: Argh, I hate my Saito .91, what gives?
Yah, upping it to 2K. I'm currently using a 15x4W which seems to be the prop of choice for this motor, however its the prop of choice for 3D pilots, I don't 3D I do acro and the guys at my field balked at me using such a big prop "You should use a 14x4...", really? I picked one up for the heck of it, is it worth it, will it be more 'reasonable'?

RE: Argh, I hate my Saito .91, what gives?
Hokay, man I felt like it was a battle of wills out there at the field today, in the end (3 hours of off-and-on tuning) I think I've got it under control. I've got a pretty low idle and when I hit the throttle it spools up with no choaking. I discovered that part of my problem was I wanted too low an idle, I got it to a good idle then tried to take it further and it didn't work so I put it back and figured I'd tach it to see where I was at, 1800RPM which turns out to be 200RPM lower then the Saito's spec :). I didn't fly it, didn't want to tempt fate, flew the Corona and chatted. Woot! Sam

RE: Argh, I hate my Saito .91, what gives?
Hah, sounds like you're speaking from experience (re DO NOT TOUCH IT). So as I was falling asleep last night I was thinking what a PITA it is that the low speed needle is on the bottom of the engine (its horizontal) and how I have to rest the plane in my styrofoam cradle upside down and run it (difficult and dangerous). When a stroke of brilliance hit me :)! Just turn the friggin carb around so the low is on top and the high is on the bottom! Duh, thats what I did when I first mounted it was switch it so high was on top, high-speed on the bottom will be easy to adjust still and low on top will no longer be a PITA, any potential problems with this setup?

RE: Argh, I hate my Saito .91, what gives?
Ok, ok, I'll keep trying, I really don't want to have to get a new engine and I do want the 4-stroker to work out as they're clearly the better engine type. Thanks for all the help/tips and keeping my will-to-go-on going cuz this is really really frustrating, but your suggestions make sense, I guess thats why guys have two planes so they can fly one when the other is acting up :D

RE: Argh, I hate my Saito .91, what gives?
OK, I haven't seen any of the other guys at the field with a saito but I'll look around. I guess I could mention what I went through at the field yesterday and maybe you'll have a comment. I have it mounted sideways (muff down, high-speed needle up), I started it up, leaned out the engine and shut it down. I flipped the plane over (now the muff is up, low-speed needle is up), started it up and started to work on the low end. I went through a whole full turn (!) on that needle adjustment and finally turned it 1/8th and got a higher RPM boost (what I was looking for) but the engine started to sound funny. I tried throttling up and it stuttered and nearly died, so I tried throttling up really really slowly and it still stuttered and nearly died. So I backed off the needle 1/4th turn, tried throttling up, it stuttered and died. Wtf? Was this because the muffler was above the engine instead of below (inverted)? Should I unmount the engine and work on it as its kind of hard to get to both needles with it mounted. Really really frustrated, I just want to pitch it out into the field X(

RE: Acrobatic scaleish plane for a Saito .91
Alas, I'm throwing in the towel on my Saito .91 and getting a new 2-stroke engine (I just wanna fly dangit), but am still considering that chipmunk or the 40 Ultimate ARF, though I'd like something slightly larger so maybe a goldberg...

Thanks for all the help guys but I'm throwing in the towel, Saito .91 fer sale. Maybe its just the engine and I'll try 4-strokes again some day but for now I just want an engine that's going to fly, I'm tired of playing with the engine.

RE: Argh, I hate my Saito .91, what gives?
Oh, no, I was going to follow the instructions which are to peak it (as lean as possible) while I'm setting my low end, after I get the low end RPM jump I'll knock off 200-300 RPM from the top so: -Start up engine, rev up and fully peak the top end (full lean) -Return to idle, lean low end by 1/8th (listen) rev up to clear carb -<repeat above step until when I lean by 1/8th I get a large increase in RPM> -Rev up and richen the top end ~300 RPM below peak -Return to idle and tweek the low end until I get a nice low idle and a good transition.

RE: Acrobatic scaleish plane for a Saito .91
I have always wanted a biplane, what bipes would work well with a Saito .91? Would a .91 work out in a DP Ultimate 40, and why doesn't the dp website list the dp ultimate 40 under their 'kits'? I'll look into that chipmunk, flaps sound cool :).

RE: Argh, I hate my Saito .91, what gives?
Ok, so the revised plan is: -lean top end all the way -throttle down and lean low end by 1/8th -throttle up to check -throttle down and lean by 1/8th again -repeat until when I throttle up it goes even higher then it had in the past (or is it until the low end has a sharp peak?) --QUESTION-- It wasn't clear, when you are saying 'you'll see a sharp increase in RPM' is that sharp increase on the TOP end or a sharp increase on the low end? And the goal is to get the idle low enough so it doesn't move, currently at my low idle it still pulls the plane slightly. Thanks for all the help guys.

Acrobatic scaleish plane for a Saito .91
I'm currently flying a funtana with a .91 but would rather fly a 'acrobatic' oriented plane then a '3D' plane methinks, what kind of good scale looking planes are out there for a .91 (Edge, extra, cap, other), fer loops, rolls, knife-edge, inverted, fast passes, etc and has the 'flies on rails' feel. The funtana is a little jerky due to the HUGE control surfaces, and flies kinda slow at open throttle (probably the prop but...). I think its time to retire the funtana...

RE: Argh, I hate my Saito .91, what gives?
Ah, the guy I talked to said the way I had it was good, perhaps 4-strokes aren't his forte :) Ok, so how long after the 'pinch' should it speed up, immedately? And the plan is (just so I got it straight, this is the first time I've heard the full tuning concept): -Set my top RPM as high (lean) as it'll go, ie tach it up and up till it drops (because its too lean) then back to top -Drop back down to idle and lean by 1/8th turn, then pinch, lean by 1/8th then pinch -Spool back up to top -Drop back down to idle and lean by 1/8th turn, then pinch, lean by 1/8th then pinch -Spool back up and repeat until when I spool up to top it goes really high at which point I should richen the top by ~200 rpm then go back and finalize the idle. Thanks!

Argh, I hate my Saito .91, what gives?
My Saito .91 is such a PITA, I can't get a low enough idle for my taste and even at the idle I've gotten it to if I spool it up then drop it back down it takes a couple seconds to get back to the low idle which makes landing a little hot, if I bring it down too low it dies :p I get the low set with a good 'pinch test' so I pinch it and in 1-2 seconds it spools up, hit the throttle and and runs up prefectly the high is set just right with my Tach then I drop it back down and it idles high for 10-15 seconds then settles back down to a low idle. The guys at the field say its running normally and that that is the idle it should run at, blech. I want a nice low rumbling idle and a 4-stroke that is easy to tune and maintain, this .91 is like a little princess, can anybody suggest an easier to deal with 4-stroke? Weight and performance are 2nd to ease of use and reliability though it should be able to run on its side or upside down without flooding. I don't want to go back to 2-stroke but will if I have to. Time to sell the Saito... Thanks.

Engine standoffs, yea or nay?
I'm sticking a ZDZ 50 on a CA 27% Extra and had originally planned on using a 1" shim on the shaft to push the prop further away from the motor so I could mount the engine further into the cowl. Well, I've changed my mind and decided to go with the 'KISS' theory but now my engine firewall is 1" to short :( Can I just use some 1" standoffs that I've seen sold at some specialty shops? I have the ZDZ mount/hardware that comes with several 1", 1/2" and 1/4" shimms but it seems like using those would rest a lot of weight on the bolts I use to bolt the engine on the firewall.... I dunno, doesn't seem like its going to be very sound, does anybody know what I'm talking about? :) Thanks in advance

Futaba 9C screen blanking problem, anybody else?
Hi, So several months after I bought my 9CHP I shut it off once and dark vertical lines appeared on the screen and stayed for a couple seconds, scared the hell out of me. I was going to send it in but in the face of it being gone for months it seemed harmless. Then the screen blanked out on me after I turned it on once, again, scared the hell out of me but if I turned it off then back on it was fine and everything still worked if the screen blanked. Now I hear from a guy I sold my 9CAP to (I swapped over to the CHP) that he is experiencing the same problem (screen blank), has anybody else had this happen to them or heard something from futaba about it? Thanks

RE: Funtaina tail section seperated at 200', now they want it mailed back?
I said I was going to fix it, but now I am, I don't care who's fault it is I just want a plane to fly. Besides, I've shored up the shortcommings of the tail section (like adding a small triangle wedge back there, geeze) and a off-axis tail wheel. Its taken me about 2 hours, but I feel it was better then sending it in, oh well. And I'll be using the short-blue arms that come with the hitec digis instead of my 1.25" airwild arms now :D
