Status: offline 		So... I'm waiting for my 260 to arrive and I just read an 80 post long review thread that I never saw before. They were saying that the plane would snap on you and does poor walls. All the guys that were saying this had big twins in their planes... 3W, BME, etc... I was wondering of any of you guys with the ZDZ-80 or 3W75 are experiencing the same thing?

Also... I just noticed the location of the elevator servos... how long are your pushrods? I am wondering if I can use the H9 pro-links (5" I have laying around.

Also... what is the setup for pull-pull, as in how are the pre-cut exit holes located? Are they cut for a straight cable run (not crossed)? what size servo arm? Do you find that a single 8611 is enough power, or is more required?

Can you please point me to that post?

If it's the one I'm thinking of (can't find it now) I believe you will find that all the posts about the 260 snapping came from one individual, but I could be wrong. I don't recall talking to him, it sounds like the plane was pretty nose heavy.

Again if he's the one I'm thinking of he changed to a 3w75 and all was well and happy. This being the case he only removed less than a pound. That's not really enough to make a radical difference so I'm thinking something else must have changed.

I have not heard any other reports of the 260 snapping or any other odd behavior. I do, however, still suggest that a lighter engine will yield a better combination.

Status: offline 		Of course... I love light. I am using a ZDZ-80 with a custom in-cowl cannister setup. I was hoping to be able to use 1 aileron servo per wing, but that seems not to be possible. What are the analog servo you use that require no matchbox?

Here's the thread:
http://www.rcuniverse.com/forum/m_2765116/mpage_1/key_wildhare%2C260/tm.htm

I can't find the one that tlaks about the walls... maybe it's the same one... I didn't read it all again.

Status: online 		I just finished and flew a plane with 645s. I found them to be disappointing. The centering was dreadful and performance was lackluster. They are slow without being particularly aggressive about holding their position.

FYI I have used digital servos (good ones, not just cheapies) on 2 servo wings probably 20 times and never had the least problem. Quit worrying about matchboxes and everybody's hype when setting up Wild Hare planes' wings.

I think I've explained this before. Use a Y cable. Start with the 2 control horns exactly the same distance from the aileron surface (or as close as your adjustment will allow) and at neutral the two servo arms should be the same angle in relationship to the pushrod. Use the same hole in the servo arms. With all of this as close to identical as you can get it, the servos are about 18" apart. If there is a few thousandths of difference in travel that little mismatch won't hurt anything and there's enough flexibility in the aileron itself to render the problem irrelevant.

Where you need to be 100% matched is on rudder on a very big plane where the servos are mounted in line with ball links and metal servo arms. In this case there is no give in the linkage, a small mismatch can burn out a motor in a hurry. But there is absolutely no need for a matchbox on a plane like the Extar 260 the way it is laid out, even with 8611s or 5945 or 5955.

Think about this. First, how long are ailerons ever at full deflection. Maybe a few seconds per flight? So what if there is a 1mm difference in the travel? The aileron will twist a little for a few seconds per flight, who cares? I've never burned out a servo, drawn my battery down, damaged anything, never ever.

Don't worry, be happy.

I did try seting up some 8611s in a wing on a Y before... they did OK... not perfect, but OK. I couldn't get the arms to line up just right on the servos. I think I'll try some Nelson arms so I can try 4 different orientations.

What size arms for the ailerons... 1" or 1 1/4"?

Status: offline 		Tom that surprises me on the 645s. I have flown both digital and 645 setup wings, and I could not tell much difference if any. Oh well, we all have to use what we like.

Status: offline 		When I go back and reread all 88 posts on that thread I see one person with the snap and wall complaint, and that was in one post. Sillyness makes it sound like there were a bunch of people saying that. Come on man, if you're going to quote a post, get it more accurate, please.

Status: offline 		Holy cow I dont see how that pissed you off. Geesh people get upset about spilled milk over here. I will be honest, when 6 of my friends got blown up by a roadside IED and I saw the body parts of three of my friends blown to bits, not to mention the bloody boodies of those who survived that blast...then I was pissed. Talking about model (toy) planes doesnt make me upset. Maybe crashing them makes me upset...lol. Easy hopefully you dont take what I said as fighting words. I tend to be aggressive having been through some crazy fighting in Afghanistan and Iraq. Things I say might come out as a little direct. Yes everything can have improvements. I think pre painted and trimmed canopies would be nice, as would CF gear stock. But hey nothing is perfect and half the fun is making things work. I am sure with future releases of any WH plane things will get better.

Tom I know you hear what people say on here so I know things will get better. Overall I am happy with my plane and even planes that cost much more I have still had problems with. I am sure I could go buy a composite ARF tommorow and find things I dont like

I think we need to settle this over some beers or something...lol.

Status: offline 		Geez guys!!!

The ONLY reason I brought up the whole deal is because there are VERY few flight reports on this plane so far... in fact those were the ONLY ones I've seen except for one more!!! I'm not trying to turn anyone off... I have this plane coming. I guess I was hoping to find cures for any problems that might exist... every plane has one or 2 bad tendancies... aerodynamics is simply a bunch of compromises... you give this and physics takes that. It looks like the problem this dude has is most likely weight and CG related, which is not surprising because I found my Extra Special to be somewhat CG sensitive as well... but once you get her dialed in she's a sweet ship!!!

CHILL FELLAS!!!

So anyway... TOM,
Do you think that the problems running the 645s were due to the fact that they are analog or that they are 645s? I am thinking of using Futaba 9206s (my first Futaba servos) for ease of matching without using the Matchbox... gives me a little more room for error and lower current drain that a couple of digitals. I read that many people are using and love this particular analog servo. I'll still use 8611s for the elevators and rudder.

Status: online 		That's a hard question. I use 5645s all the time and they are great except that they also do not center well, but they seem to be better than the 645s I used. 645 is just a 5645 without the digital driver amp.

So I don't really know. There was nothing really wrong with them, they were just unimpressive.
