Congratulations Tom! She looks great. I was glad to come on here and see that she flew this time. Cool flight report too.

If your Tiger is twitchy, you can add more exponential to the ailerons and elevator. You probably already know this, but just in case, make sure you add negative expo if you have a Futaba or Hitec radio, and positive if you have a JR.

Thanks!!!

The twitchiness is from the wind influence, not the control inputs. Without the differential though, it is definitely twitchy due to the controls!!

Hmmm, hadn't realized the differential is different based upon the radio. My preferred radio is my Futaba T9CAP. However, I've gone DSS with a DX7, which is a JR variant. Will have to keep that in mind when I get the Spektrum modules for the T9CAP.


Oh, and the other thing I'm going to do is turn the muffler. I'm going to point it up and away from the plane. Right now, I've got an extension pointing it right an the landing gear. I'm still getting too much residue on the wing and tail. Hopefully, blowing it away will help. If not, I'll get a different extension and run it down below the wing and pointed down.

I'm certainly glad I found this forum as well as this thread!

I'm getting back into R/C after a 20 year layoff. I'm starting with the basics, training on a Hanger 9 Easy 2 ARF for now, and I've decided on the Tiger 60 for my low wing trainer. ARF is nice, but I've always enjoyed building.

Lots of good info here and some really helpful people!

Well, it was a beautiful day at the field!! That is until my tail broke off several hundred feet up!! This time she''s a total loss!! Well, airframe, anyway. I'll recover the engine, and electronics. Photo posted in the Crash & Rebuild forum.

Sorry to hear that Tom [] That's a cryin' shame for sure.

Ok, it taken quite a while but here are some pics of where I am at so far. I have only connect the aeliron and button down the canopy and
it's off to the field. I think I will run some yellow stripes down the bottom of the horizontal stab to break up the black.

Let me know what you think... BTW my daughter gets credit for donating the pilot!


Details:

OS FS 91 13X8 APC Futaba radio gear...

Dlan,

Looks great!!! Best of luck with the maiden. Remember to dial in some differential, and don't have your rates set too high!.

What do you folks think abiout hanging an OS .65 on a Tiger 60?

I know that the Saito or OS .91 4 stroke is a great engine for this airplane, but the Tiger is going to be my first low wing trainer and I'd rather bury a less inexpensive motor in the dirt.

Assuming it's a 2-stroke 65 it should fly just fine! It's at the upper end of what is spec'd for the plane...

BTW - don't think about burring it, be positive
I know when I asked friend who has been flying for years about crashing, he said it's not a matter of IF rather WHEN...
Either way, be conservative at the beginning and not too "cocky" and it's all fun!

Dlan--She looks awesome and good luck with your first flight!

Sweet!

Don't dork it on your maiden. LOL

Thanks for your support B, I have a plan... [sm=drowning.gif]

Ok, It is ready for flight. But I have a question. I balanced at 4" and the plane is ~9lbs!!!
I am using a FS 91 OS. the weight is approximate on a crappy bathroom scale. I took about
7oz of weight to balance (yikes), Any comments, concerns????

Thanks!!

dlan, I balanced mine at 4 1/4" initially and it was still nose-heavy, so I removed some weight from the nose. Not sure where mine is at currently, but I would think it's around 4 1/2" or so. I wouldn't have any concerns about the weight otherwise - who knows how accurate our bathroom scales are anyways. The Tiger has so much wing area and is so docile that another pound isn't going to make a big difference. The 91 will pull it around no problem.

BTW, nice looking plane! Good luck on the maiden.

Thanks AvNut! Next Friday is the day baring any unforseen responsibilities popping up... I'll get back to the thread once its been off the ground (fingers crossed!!!)

My Tiger 60 is scheduled to be delivered today!

I've been poring over this thread and have several hints, tips and tricks that I will incorporate into my project.

Can someone help with aileron differential. I have a Tiger 60 powered with a Magnum 91 and it flies great except when I roll, where it has a tendency to dive. If I do more than one consecutive roll it it ends up in a vertical dive. Almost lost it (thank god for the "3 mistakes high" theory). I assume I need to program differential into the ailerons. But in what direction. Assumiming I roll right, do I want less left aileron (down) or less right aileron (up).

m_skaggs,

Are you giving it a shot of down elevator (up stick) when the plane hits the inverted portion of the roll? I used to have the same problem, until someone told me of this. When flying inverted, the plane is going to try going nose down unless you give it down elevator to push the nose back toward the sky. In a roll, you just have to do it for the brief moment that the plane is inverted. (And to really do the roll correctly, you'd give left and right elevator to keep the nose level when the plane is on its side, too.)

Tessex,

Yes, I give it down elevator. It just seems when I roll, it takes more down elevator (pretty much full down) to keep it from diving than when I simply fly inverted. It makes sense what you say about the rudder input. Of course, the rudder on the Tiger doesn't work that good and I'm not that coordinted.

I could be wrong about the aileron differential. I thought I had read somewhere that this tendency to dive in a roll could be caused by too much deflection in one aileron vs. the other. Now I can't find where I had read it.

Sounds like you could have balance issues.
If it takes a lot of down elevator (>20%) to maintain level inverted flight, then the plane may be too nose heavy.

Not a lot, but every time you roll, the nose dips a touch more and it adds up. Doesn't take too many rolls before you're diving to the ground if you don't correct for that little bit.

hello everyone,i have been following this post with great interest.would just like to say its been quite helpful and am posting some pictures of my tiger 60 deluxe.its been kit built,completely sheeted,glassed and painted.has an OS 91 fs,13x6 zinger,robart retracts.

RE: My roll problem. I went to the field today and I've got it figured out. I was applying too much elevator and at the wrong time. I was almost simultaniously pushing the stick to the side and giving down elevator (pushing the stick to the corner). I relaxed a little today and started my roll, added a little down elevator just as it was going inverted, then let off the elevator as the plane rolled out the other side. Basically, it's my piloting skills not the plane.

Now one more question. I am going to convert my Tiger to a tail dragger. Can I use he same size wheels for the mains? And what size tail wheel does anybody recommend? (I guess that's two questions).

freddy_s, sweet looking plane!! How much does she weigh? Have you flown her yet? If so, how' does she fly?

m_skaggs, Cool beans on the rolls!! I actually used Realflight and set my camera into follow mode and kept going back and forth until I worked out my roll timing. It's really neat to see a plane rolling across the sky and then realize it's yours!!

As for the taildragger. I used the same size wheels as recommended when I built mine as a tail dragger. Actually, come to think of it, that was the gear that started on my Tiger II. You do need to get the mains in front of the CG, though. I used fiberglass struts bolted into the fuselage, right in front of the wing. (Just make sure you reinforce the floor first!)

Very nice indeed! I too am curious on the weight of your plane...[8D]
