I think I'm going to convert mine to EP.  Everything else in my hanger is EP and I just can't deal with the headache of trying to tune this inverted supertigre.  I feel more comfortable with EP.  I'm thinking about a power 90. on 6s hopefully.

Aero,
My plane is set up with a Power 90 as is Bob's. If you build a box to slide your battery back under the cockpit as we did you should be able to pick between a 6s 5000 mah, 6s 4000 mah, or 8s 4000 mah pack without changing your CG too much. Only the all-up weight and power will change. My plane is finished, I am only waiting for a decent "maiden day" to fly it. I am not sure which pack I will try first but I have all three available. I will let you know when I get a chance to fly it.

Having said that (above), jw's plane on a Power 110 and 10s 4000 mah pack seemed to fly very well and, I am certain, was not lacking for power...!

I just picked up some Zippy 4 cell 4000 mah packs and they came in at 400 grams each, which keeps me in my CG range and should give a good balance of power and flight time.

Jim- can't wait to see your results, and which prop flys best with each set up! 

We are having a warm up here and the field that I fly was snow covered last week - I put up my foamy T-28 with skis what a kick to take off and land on skis!  But cant wait to fly with gears up!!!!!

COME ON SPRING!!!!!

Forgot to add the pciture of the T-28 with skis!

Bob, nice pics! I think I will use and APC 14x10 for the 6s set-up and an APC 16x8 for the 8s, at least initially. That is, if it ever stops raining out here!
Jim

Aero Lex

Well I was certainly hoping to use 6s on this setup, but all of the information I've read says that maybe 6s isnt enough power. So I guess I will have to do an 8s setup. 16x8 is a massive prop for this thing! my current engine is only doing a 13x7. I sincerely hope your 6 cell setup has enough oomph. Looking forward to hearing your results

Okay, today was the day. I took the plane out to the field and considered which battery pack to use. Ultimately I decided on the 4000 mah 4s (x2) packs as the 6s pack simply did not seem to have enough thrust looking at it on the ground. I used the APC 14x10 prop. It was cloudy with a little cross wind but a pretty good day for March in these parts. I lined up on the runnway, hit the electrons, and the plane was off the ground within 50-70 feet! I was really suprised as it just popped off the ground and I thought it might be a little tail heavy. Not the case. I pulled up the gear and cruised around a few laps and found I needed no trim to keep it straight and level. I was pretty impressed as the plane felt a lot lighter in the air than the 10lbs 12 oz it weighs. It had plenty of power at slightly over half throttle and a definite kick when the power was turned up. I did one full power climbing turn and then one roll. After that, while turning back to the field the plane went into a spiral dive and killed itself. No real control except I did have throttle so I was fairly sure it was a mechanical failure.

The plane is toast. I will post pictures tomorrow and do have a video which I will try to post soon. Now, on examining the wreckage I noted that both plywood aileron mounts had popped off of the servo covers where they are mounted. I will post pictures of these too. These mounts fit into a slot in the cover and are (supposed to be) glued in. I could see a little glue around the edges but none where the inserted mount fits into the servo cover. The wood looks as if it never had glue on it. My feeling is that one of these mounts popped out jamming the aileron causing loss of control. Upon hitting the ground the other one must have also popped out. I strongly advise anyone out there with this plane to look carefully at this structural part of the plane before flying!

Horizon has had absolutely first rate product support in the past and I am hoping they will cover this loss by supplying me with a new kit. They have done this for me in the past
(H-9 85cc Sukhoi) when I had a similar problem. They sent a shipping label and I boxed up the remains and sent it back to them. They replace the plane. I will ask them to do the same for this plane. Whatever happens I will get another T-6, salvage what I can from the wreckage, and get it back in the air. I also highly recommend the Power 90 on 8 cells as a power source. Of course, the landing was a little rough.

Sorry to hear the sad news!

WOWthis is the 2nd t-6 to go down - tough start!!! Although one was a tree that jumped up and grabbed the plane from the sky

What a bummer, i will have to check my servo mounts for my aileron mounts, not sure how i can check the glue, but it will give them a tug an pull, and pry to see if the mounts pop off.

So the 14x10 prop was plently of power, ths is good news, Iwas going to start off with a 16x8.

Please let us know what HHsays about the issue. Sorry again

Bob

Okay, here are a few pics of the carnage and the aileron mount. You can see looking at the mounts that there is only glue around the mount and the wood popped cleanly out of the slot it was inserted into. Maybe a little thin CA, although that does not work very well on plywood. I think I will add some triangular stock around the mount??? on my new plane.

Oops, the pictures did not load. I will try again.

And, a few more.

thanks for the pictures

Iam taking a look at mine right now

It will suck if you lost her due to 2 cents in epoxy!

deuce77

There is no epoxy in this plane that I can see. It looks like they just put a little hot glue around the joints and called it good. But...the plane does fly quite nicely and would probably fly quite well on 6 cells. That would be 5 oz lighter. But the power on 8 cells was very good and it must be over the top on 10 cells with a 110!

Ipulled and pryed on my aileron mounts and did not feel any give, but Idid epoxy a piece of balsa on both ailerons just to be safe.

Assoon as the field dries up Iwill put her up with my 8 cells and a 16x8 xoar prop - Iwill do some more testing with the xoar props (Ihave both 16x10 and 16x8)and see what my results are.

Here is a picture of what Idid to add a bit of extra support to my ailerons! Ialso put a piece of double sided tape to the servo and servo deck- just as a extra bit of precaution!

I always add a layer of epoxy on the arf's that already have the servo mount blocks on, most seem barely glued on with what looks like hot glue from these factories.
Sorry for your loss.
I have rebuilt most of mine, but sadly my lighting systen doesn't work anymore, all that's left to do now is to re-cover the areas on the wing that have been patched.
It wuld be done tonite but being a new father means it'll be a while before I have time to figit with it again...Maybe in anothere week or 2 I can squeeze the time in.

Glad to hear you got her back together

The snow is gone here, but now the spring rains.  I hope to have mine up in a few weeks, 

I have gone over here a few times now, and my CG and wieght are good.  One last thing to do is to test how much pull she has with a 16x8 xoar prop.  BUt I am ready to fly!!!

NoFlaps,
Congratulations on the "new father" status. I well know that that is a life changer but well worth the effort! There are a few things that really are more important than "toy" airplanes and that is one.
Good job getting that plane back together. Mine is truly not fixable but I will build another.

Bob, if your are having any questions as to which prop to use I can assure you that the APC 14x10 really feels good on this plane with that power system...in my very limited time on the sticks.
Jim

My Feedback: (4)

I will pick one up

I now have a big collection of props

I will let you know how the testing goes and I will try to fly with both props.  I am still new to the game and the prop selection is still the biggest mystery to me.

Aero Lex

Quick question for you guys with power 90s or even possibly power110 and Tru Turn spinners:What adapter did you order to fit the prop shaft? The nose bolt is just slightly too big to fit inside the hole on the prop shaft. Also, the prop adapters I already have are made for the Super Tigre, so, they're just slightly too small. It's kind of bumming me out.

jwjohnson

On my power 110 I used the reverse adaptor and drilled a hole in the center of it and tapped it to accept the screw from the Tru Turn spinner.  I'll try to take some pictures and post them, but it won't be for a couple of days d/t work.

deuce77

jw,
As an option, you can use the TruTurn adaptor for outrunners: TTE-08394-A. http://www.truturn.com/cgi-bin/store...exact_match=on
That is the one I used and it worked perfectly for their spinner. Price is $22.95.

jw,
Oh yeah, I failed to mention that with the above adaptor, my plane crashed and destroyed itself...!
