Is everyone setting up with the dual rudder servos?

I plan to use 2 Futaba S3305 High Torque Metal Gear servos connected in line for the pull-pull system.

no need for two servo's. 1 is more than enough if you use a good servo. hitec 5945, 5955 even a 5645 would do. jr 8611 good also. some guys run a single servo in 33% planes. your also adding weight with two servo's.

I'd have to agree... setting up two lower-end servos to do what one strong servo can do is heavier, more tedious to setup and provides another potential failure point. And if the servos aren't matched well, you can get fighting which can decrease flight time and perhaps even shorten the life of one or both servos.

So do you think that one Futaba S3305 High Torque Metal Gear servo will be enough for the rudder's pull-pull system? It will be running off of a 6v 2000 MaH NiMhd with 90 inche/ounces of torque. I could also mount it at the rear directly to the rudder.

I used one JR 8611A. and the plane will knife-edge-loop with ease. The cost is about the same as two servos and you avoid the issue of the servos fighting each other. I also added some support to the rudder-tray to handle the load of the pull-pull wire tension.

Lou55,

That servo will do 124 oz in on 6 volt... but that's still a little low for "all out 3D" you'd probably get some blowback.

I'd recommend looking at a minimum of 175-200+ oz in.

HiTec 5945, Hitec 5955, JR 8611a, Futaba 9153 would all be excellent choices.

Keep in mind that this is a GREAT investment and can move with you from plane to plane.

Also, I'm sure you already know... but you cna put a JR/HiTec servo on a Futaba receiver with other Futaba servos... Mixing and matching is fine...

With the da 50, did you tail mount the elevator and rudder servos???? which standoffs did you use as well?? did you double up the rudder servos in the fuse, 1 per side??

Need help selecting servos. On rudder, I'm looking at JR 8611. I'm undecided on elevator and ailersons. Looking at the Hitch digital servos, but not sure between metal or titanium gears?

Any advise would be great.

Thanks

Always buy the best you can buy and you can't go wrong.

On the other side of the coin, the 5955's are probably overkill for this plane... But I would get one over the 8611 for rudder anyday.

HiTec 5945's are really good servos for ths plane. I've got more moderately priced Futaba HD STarndard servos in the ailerons and elevators in mine and they are more than fine. I have a Futaba S9351 Digital on the rudder.. plenty of authority.

5945's is a good choice and it's also what i'm running. if you wanted to save a few bucks that would be more than enough for the rudder also. if not, go with the 5955. just as strong as the 8611 but it has titanium gears that won't wear down as quickly as the metal one's in the 8611. I run both of them and they are both very good servo's. do you have servo's for your ailerons? if not donalds hobby shop http://www.donalds-hobby.com/Prod/sc...idProduct=1089 has a good deal on a 4 pack of 5945's. $300 / which comes out to $75 a piece. normally $89 a piece. if your getting just 2 servo's i'd go to tower. they have a discount for buying 2 comes out to $87 a piece.

I'm running a Suter Tigre 2300 on a perry pump and carb that runs very good. I only run a 16 X 8 prop and it realy spins it. I don't think it will spin a 18 X 8 very well. With 3D you will want good excelleration on the prop and I get that with a 16 X 8, but I don't think it will with an 18 X 8.

Your 2300 should spin an 18x8W APC with authority. You could also try an 18x6W APC. My neighbor is flying his 25% Giles with a 2300 and an 18x8W.

Thanks for the feedback, looks like the 5945's are the way I'll go for ail / elev... Maybe the 5955 on rudder.

Next question: I've recently started using lipos on most of my stuff, only makes sense to go lipo on this plane. What Mah should I run, 2400mah? and is it ok on 6 volts?

Thanks

2100+ should be fine... you'll need a 6 volt regulator with a 2 cell lipo as they are 7.4+ volts.

I'm still not convinced Lipos are as reliable as I would want for receiver power on larger combustion powered planes... Probably just gunshy...

I'd wither get a 2 cell 2400 Lion or better yet a simple 5 cell 2500 mah Nimh... no reg... just plug and go and not too much beavier than the lipo/reg setup..

Chief aircraft carries a 5 cell JR 6V NimhD 2300 for about 30 bucks.

Well my CAP finally arrived and looks great!! A little wrinkling in the wings but nothing a heat gun won't fix. This one should be fun, it's HUGE!!

Well I finally got it finished today. About 22 hours total construct time. Plane is a work of art. Really can't wait to get it broke in and in the air. Put in an EDR on-board glow driver so I didn't have to put another hole in the cowl.

Question regarding wing center section.... Is there a need for any additional reinforcement? Seems a little on the light side to me but I haven't actually started building the plane yet.

Thanks

mine was built per instructions. it's a lite plane. I do full power upward snaps with os 1.60 no problem's.

Yep have pounded mine with no probelms with the wing... build as instructed...

I'm going to run a APC 18x8W on this with the 1.60 in it after break in. Any thoughts on that prop choice? I have an 18x6W on it to break the engine in.

I have not run your prop but have used both the 18 x 6 and the 18 x 8 Mejzlik props on my OS 1.60's in Chipmunks, Giles 202's and this Cap 232. The motor handles them well and they gave good flight characteristics.

I would fly it (the CAP) with the 18 x 6W to keep the engine cool and also keep the speed down.

Regards,

Eric.

I'm about to get into the 1/4 scale fun for the first time. On this cap, do you think a SuperTigre G-3250 is overkill? Would the 2300 be sufficient or limit my 3d capability? Also, with the OS 1.6, does it tend to be nose or tail heavy?

Hi everybody,

I ordered one also (but out of stock everywhere, I have to wait a couple of weeks[>:])
However, here is the question: i will use the OS 160FX, too. Will the original OS silencer(#5010) fit under the cowl? I've got the engine with silencer last week and it seems to be HUGE.
