Pay for the shipping & you can have 'em. A friend has them on the Vision,he has no complaints except the need for adjusting the travel.
What size tank do you recommend for the DA 50?

RE: Its Here!! Double Vision
 

16 oz always gives me plenty of flight time... an easy 20+ minutes til dry... I fly 10-12 minutes and have a 1/2 tank left...

Sent ya a PM

RE: Its Here!! Double Vision
 

I usually go for 17-20 minutes each flight,I hog the field! Maybe I'll start with a 20 oz.

RE: Its Here!! Double Vision
 

Just discovered the servo wells in the wings are too shallow. Hadda shim them up. Not a major deal, but surprising. Are they all like this?

RE: Its Here!! Double Vision
 

Depends on the servos you chose... some are deeper than others... My HS-5625's are fine... close, but no problem...

The spacer plates are a fine solution to taller servos...

RE: Its Here!! Double Vision
 

I'm using HS-645's. Same size as yours. The plane is S/N 115. It's not my imagination. Had to add 1/8" shims.

RE: Its Here!! Double Vision
 

There are some differences from the manual on this plane. The struts are totally different. Two pins and one screw instead of the threaded fittings that are shown.

RE: Its Here!! Double Vision
 

Might be some slight changes in the SE (the one I have built is the first batch) wasn't implying you were imagining anything... just mine are not touching the opposite side. As I mentioned your spacer plate is a fine "fix". (Just a thought... you did have your servo grommets in place when you checked the depth... I'm sure you did but sometimes one can forget when checking size...)

Yep... the manual needed some updating but never got it...

Older versions have two posts that screw into each end of each wing... that provides holes for 4 screws each strut to pass through... took a little time to assemble.

The SE struts have two alignment pics that poke into the wing and a screw comes in from the top and bottom wing to hold it all together... faster assmebly/disassembly....

On the one I plane to strip, lighten and recover, I am going to see if retoritting to GP's knurled studs would work... I love them n the GP ultimate...

No tools needed....

RE: Its Here!! Double Vision
 

You are not the lone ranger, mine bottom out also it's close but they don't quite fit, using 5645's on ailerons. 8411's don't fit either oh well not that big a problem

RE: Its Here!! Double Vision
 

Yeah, not a big deal. It took an1/8" shim to clear the problem. On the struts, I was just concerned with only one screw holding the strut. With wing twisting and flexing, it might put some strain on that one screw. Otherwise, tho', it's a great lookin' plane!

RE: Its Here!! Double Vision
 

Maudib, re p. 25 of the directions, the pic seems to show the cabane struts mounted backwards. On mine, taking care to measure the width of the two 'v's' and putting the taller one on the front, the diagonal side rails run from top front to lower rear. They're show the opposite. Hmmmmm. BTW, my crack about imagining was just a poor attempt at humor!

RE: Its Here!! Double Vision
 

Tee hee.. I know... :)

Yeah... the manual has some inconsistencies... it's a slightly modified 2nd verion... of the original... that doesn't actually cover the SE edition...

I have not accembled either of my SE's yet... so I can't say from experience...

But on the first version (at least mine are) the cross braces are as shown in the manual... and the plane flies AWESOME... I have heard other guys building theirs that didn't liek it... and I can ONLY think the cabanes were wrong...

Mote that even the manual and first batch were different somehwat... int hat the center rib section was like 1" on the prototype and maybe 3" on the release...

The new scheme also had some changes tot eh design... not huge... but enough... I noticed in the "factory pics" that the cabanes were installed the other way around.... not that doesn't mean they got it right... but it's an indicator... and I recall Chip telling me the manual showed it backwards... but I can't recall enough to say for SURE....

The factory pics showed the new scheme... but this was NOT the DVSE... but the second version with new scheme... I DON'T THINK there were any structural changes to the SE other than the hole in the firewall...

See these pics...

1: Manual
2: My first batch DV
3: The factory 2nd batch photo

RE: Its Here!! Double Vision
 

Again... looking at these pics I think you can see that on mine... the cabanes follow the slant down of the turtledeck... whereas the NEW version has the cabane rails inside the fuse parallel to the thrust line (or hatchline if you will).

So on MINE I think the longer one went up front BECAUSE of the slant downward EVEN though the rib is thicker there... Where as the newer version I think needs the longer one in the rear because the rib is thinner at the rear and the bases are the same....

Can you confirm this on you plane?

RE: Its Here!! Double Vision
 

I should also note that I've seen two other first revs DV's with them JUST the opposite of mine... go figure... but I love how mine flies and the wings don't seem to need any "twisting" to get them into the struts...

If you can check incidence... check the hatch base against the centerline of the upper rib section.

I'm thinking that if the cabane mounting rails are indeed parallel to the hatchline (which should also be the thrust line) then the shorter A frame should be in the front to compensate for the thickness of the rib... to heck with the direction fo the cross braces...

And what CHip told me was wrong about the manual... don't know if it was the PIC that no longer was correct or whether the directions to put the taller one at which end.

He's been a little harder to get a hold of lately.... I'll put in an e-mail to him...

RE: Its Here!! Double Vision
 

Bob
i had the same trouble on the DV number two that i had,i tried to but the cabane on just like the first one,but i had to do a lot of twisting the wings to line up with the struts,you will know if it is rite the wings will line up easy and fall into place,if i still had DV no. two i could tell you for sure.
ENJOY!

RE: Its Here!! Double Vision
 

Has anyone smoked theirs yet? I've got one of the second run's(?) I think. I've already put a coupla test flights on it and it's excellent. Can't wait for the rain to stop so I can get it out there again. I was thinking, (whilst it was raining) of using a skywriter I had laying around and putting smoke on it but would prefer to see how someone else has done it though and was wondering if it was a big performance trade off. I called myself breezing through this and a couple of other threads and haven't found what I'm looking for. Any info?

Thanks

RE: Its Here!! Double Vision
 

Howdy. My plane is like your 2nd batch pic. s/n 115. Don't know if that's 2nd batch or not. Hope so. I didn't mean to twist the wings to assemble them, I was referring to flight loads and whether one screw in each strut would be enough. I think I almost definitely might know what y'all mean about incidence. If you get more info please let me know. I really appreciate your inputs. Oh yeah, mine is an SE. I'm thinkin' ya gotta put the wings on with strut in place, two halves at once. Am I makin' any sense?

RE: Its Here!! Double Vision
 

Since you have a serial number... it is the SE edition (the last batch made)

One screw will be fine...

Closetguy was refering to which cabane setup is correct... when wrong... the wings will not "settle in" to the struts and you have to twist them if they are not right... this will be easier to see because of the single screw... you can't really twist and hold htem out of alignment...

So when the cabanes are correct (I think you may have them so) the wings will sit nice and flush into the saddles of the stryts with no gaps...

RE: Its Here!! Double Vision
 

The cabane struts are backwards on the SE version. Also, you will not have any problems with one screw in the struts. The pins hold everything tight and there is no play in the struts when it is all bolted up. To setup my cabane struts, I installed my top and bottom wing and bolted up the struts, leaving the cabane struts loose. You may need to drill a slightly elongated hole in the cabane strut to line it up exactly. Once you have the two wings tight you should have 0 degrees on both. You can then install your cabane struts and tighten down the screws into the fuse. This should line everything up and is very easy. If you hold the cabane struts up to the fuse with the two wings bolted together, you will very easily see which one goes in the front or the back. This method was discribed by Chip somewhere but I don't remember where it was. I had my 50th flight on mine last week and all is holding up well. If you go to page 4 of the 38% extra Colombo Anderson build thread on flying cirkus, there is a video of Joe Hunt tearing it up last week:D

RE: Its Here!! Double Vision
 

Thanks guys. Good advice. I'm not to the point I can put everything together. Bottom line, if everything lines up easily, it's probably the right way, right? In case you can't tell, this is my first bipe. Sure is a beauty, tho', isn't it. BTW maudib, my girl say Ashland is a beautiful place. Rock on!

RE: Its Here!! Double Vision
 

I got one of the DV's that was not predrilled for the DA fiddy.......isin't it funny the reason I bought the combo w/ the da from Chief was for the ease of assembly.....can any of you guys give me some measurements on where to cut the hole for the carb at.

RE: Its Here!! Double Vision
 

Here's the templates (original and Rev2)... make sure to print it out in Adobe Reader with Page Scaling = NONE under Page Handleing......

The center "glob" it the approximate cutout required... On REV2 the only difference is I rotated it 180 degrees from the original as the engines now come with the needles on theh left and the linkage on the right (as seen from the front of the plane, inverted engine. If your engine happens to be the opposite let us know.


The SE's came with a big round hole cutout... so I added one on here (light gray) choose what you will.

If this template does not seem to fit the firewall... let me know... it should be real close though...

RE: Its Here!! Double Vision
 

Maudib,

Thanks for the engine templates. My SE came undrilled also, so the template will be a big help. Can anyone clarify the following:

1. When I install my cabanes with the taller a-frame in front, and shorter a-frame to the rear, this results in the cabane cross braces running from the top of the front a-frame to the bottom of the rear a-frame. This is opposite of what is shown in the manual. Is the manual wrong as to the direction of the cross braces or do I need to put the taller a-frame at the rear?

2. The DA-50 engine mounting template shows stand-offs of about 2.67 inches (6.421 - 3.751). A lot of the early posts about the DV indicated that stand-offs of about 1.75" were the correct size to use (even though the engine is supplied with 2.5 inch stand-offs). In one post, Chip was pretty adamant that the short stand-offs were the way to go. What's the current wisdom say regarding stand-off length for the DVSE?

Tony

RE: Its Here!! Double Vision
 

1.75" is what is supplied with the SE's that came with them...

Chip's original had 1.25" I think... and I ended up using 1/2" spacers with 1.25" specified (1.75" total) and they worked great... I suppose after some deliberation... Chip changed to 1.75"

I wish I could tell you which cabane goes where... but this is sill quite the mystery persay...

Put the cabanes in as you say (with the cross brace running backward to the pic) but don't tighten them or put nuts on...

Assemble the lower wing and upperwing with the struts in place... then simply check to see if it all falls together... if not switch the cabane towers and see then...

Can you confirm if the mounting rails for the cabanes inside the fuse run salnted down toward the nose like the stringers, or are the paralle tot he hatch (and NOT runing parallel to teh stringers in the nose? See attached pic shoing V1 and the rails rind downward witht eh stringers...

I put an e-mail into Chip, but he's swamped... he's in the process of downsizing... Chief will carry his planes (at least for now) and he will be selling only the horns, pipes and DVD's fromhis website.

He has gone back to a "regular" job... this may not bode well for the future of the models... so that's why I say GET A BACKUP of the DV while you can...

I WAS going to sell one of my 2 backups... but now there ain't NO way... :)
