Mike,

I used to use them on 8411's, 4721's etc... They are called output shaft supporters.
I havent seen them used by anyone in a long time though.

Maybe I am missing something but, mine seem to be fine with the old cases and the pull pull wire on top of the servo arm.

Here are a couple more pics of another one finshed ready for its maiden flight today.
Nice plane, but what are "Fromenco" batteries??? Who did your graphics?

The way I see it, if the big dogs and their 40% planes are doing fine with the servos the way they are, doubt people will have a problem with these planes... Although it does make sense to keep the push-pull wires as low as possible.... This is all fairly new ground for me... I did build a 1/3 scale sukhoi, but it only survived around 40 flights.... so I can't wait to start learning all this 3D stuff

I was hoping to get this thing out this week for a first flight, the weatherman feels otherwise......[]

Wayne, will Chris have the bigger yak prototype at Toledo?? That would be fun to see.....

"First thing is, for those of you using the SWB rudder servo arm, why aren't you mounting the ball links on the bottom of the servo arm???"


Bodyworks are you using the SWB arm and if so where did you place your exit slots for the cables relative to the manual directed cutouts?
I cut the slots right where they tell you to, and yes, I am using SWB and, YES I mounted my ball links on the bottom of the arm. changing the height of the mounting location by 1/4" at the servo makes about a 1/128" difference, or less at the fuse cutout, if that's what you are worried about.

BTW, I have just the 8611 on my rudder. I am not worried about that wear so much right now, but I will ask JR if they are giving any tops out at Toledo. This servo has a TON of slop at neutral!!! With the cables plenty tight, I can move the trailing edge 1/4" in each direction! MY Hitecs, while WAY louder, don't have that slop.

... The Smart-Fly goes between the battery and the switch for the ignition...
Also, make sure the Smart-Fly unit is on a Rx channel that provides 100% positive signal, like the landing gear switch... Not one that is on a knob... Been there, done that...

Actually, the on/off switch is supposed to go between the battery and smart-fly>this is so you have a positive power cutoff from the smart-fly, which will drain the battery even with the receiver off...that much I know!
Anyway, I got it fixed, but not without some serious solder surgery!! I didn't account for the switch so now my sleek wiring setup is looking like a mess! Oh well[]
I have pretty much got everything setup, except the pipe and fuel line routing, and I removed the engine to epoxy the firewall and such. hopefully the wife will let me work on it tomorrow so I can get it done!
Gee, I guess I'll have to re-wire all my airplanes that have a Smart-Fly ignition cutt-off...

All my airplanes with the Smart-Fly unit are wired in the manner I have described and I've never had an issue with the ignition batteries being drained...

Buena Suerte...

Mark

The drain they speak of is likely a few milliamps, so you probably won't notice it, plus, you still have the added safety feature of a second cutoff. But recheck your instructions...it is the way I say

I am not sure what he is bringing for everyone to see.
My guess is yes it will be there.

Bodyworks,

Fromeco is somewhat of a new guy on the Li-ion battery market.
Drew has been using his stuff for a long time and seems to really like all of it.

Last week I had a RX pack go bad in my 40% so I went to grab a spare that I had lying around. Long story short, all of my spares had problems.
It was time to switch to Fromeco.
His prices are MUCH cheaper than the other brand and the packs have matched cells.
I got the new stuff here on Friday and flew them yesterday. 2-4800 packs and one 2400 Ign pack.
6 flights on a 40% plane running 9 large digital servos and at the end of the day I was reading 7.6V under a one amp load.
The TX battery is the limiting factor now.
Good stuff!

My Yak has Poweflite batteries in them now but since they are out of business I will be switching to Fromeco's soon.

Torqued-Up, yes I do fly behind Salem, but I also fly at a field in Bedford that is much better to me. The field behind Timber Truss is not that great!

Fromeco has the best customer service around, and Kurt is quick to respond to emails. Go to www.fromeco.org to check out their products. I love their stuff, as it is a quality product.

How do you guys get an original quote in your message with the words highlighted or underlined?

thanks
Jon

Has anyone ordered the DA logo in the "crushed ice" vinyl?I really like the look of it but have not been able to get a responce from the graphics place that EF uses.Are the any other places that use that type of material?

I get all of my graphics from aero3dfx, and I have been very happy with their service. Just ask, and I am sure they will cut whatever you want.

Wayne, I think Bodyworks had reference to the Typo it's spelled Fromenco on his airplane !! I think it was a rhetorical question.

LOL.. Now that I look at it I think your right.
Oh well. Maybe someone who didnt know about Fromeco does now.

I decided to measure the drain they speak of...including the smart-fly regulator, you're looking at 6.3 mah....not much.

Has anyone tried the new snaplock's from Slimline. These are used to keep connectors from pulling apart. I used heat shrink on the majority of mine, but I am going to use these on the ailerons. I guess you could easily glue or epoxy these down also.

Check em out!

LOL!!!!! I know what Fromeco is, I am using these batteries that Kurt builds myself...my question was what is fromeNco, as that is what the decal says on hw123's plane

Yes, those are excellent, but like you said, glue them down, as the sticky tape on them does not hold up well.

Those look pretty good! I'll look for some tomorrow if I can break away from building my Yak. I didn't get a lot done today so it'll be a long day tomorrow to finish it up.

I got everything done now except the final mounting of the Rx battery and the decals. I was within 2 or so ounces of my origional estimate...15lbs, 8.2 ounces. A little heavier than I wanted (remember, though, that I am using the Hyde silencer), and I may have to sacrifice another 2 ounces by switching back to the dubro wheels...the Dave browns don't like the 15 pounds!!!
I also will have to mount the battery about half way hanging off the end of the firewall to get this thing to balance at 7 1/8"...hmmm
Here's the aircraft mechanic in me at work... I used .025 stainless safety wire to secure the 1/4X20 bolts at the firewall. This way I didn't have to overtighten and crush the ply and I don't have to worry about them coming loose. I later isolated the wire with a dab of silicone at each bolt to prevent any harmonic vibration...

Do you guys find it necessary to run a fuel filter if your fueling setup has a filter system on it?

hw123,
Where did you get the White JR decals on the rudder? Are they vinyl and what is the demensions of the JR logo?
Thanks,
Doug

I was wondering about the fuel filter issue as well!
My firewall seems awfully soft also. I read where someone suggested a couple small dowels and that got me to thinking. I am planning to drill four small holes around each bolt hole and epoxy in a short piece of carbon rod. That should be much stronger and more crush resistant than a dowel. I have some .080 carbon that should be just about right.
Does the ignition box need foam padding or anything? It looks like Drew's box on his site has mounting ears on it. Mine is just a plain box.
DrScoles, did you do anything to keep your elevator extensions from falling back inside the fuse when your stabs are off? I can't use the 24" extensions I originally bought, they are just too short. I'll have to get a pair of 36" or just double up extensions and get a couple more 12"ers. I wonder how much power loss is in an additional connector?
Do you use tygon inside the tank? I cut a piece and put the clunk on it but it's too stiff to fall on it's own. Instructions with the gas stopper say to use the black stuff (brain fart, I can't think of the name). The next size down in tygon might be flexible enough but I don't have any handy.
