Video
The first 15 seconds is my brothers attempt to get the launch on tape. I had to let him go after that.
New stock Thunder Tiger Pro 46 running just a tad rich. The prop is a cut down sport APC 8.75 x 8.
36 meg. You may want to right click and download first.
The faster runs appear to be close to 120 mph. The last fast pass at the seems to be the fastest. Ready for some serious power now.

Edit - Added a single high speed pass for dial up. 1.3 meg

Sure looked pretty fast, have yet to see the big movie.

The Wave-O-Scope Doppler program was showing about 120 mph. Some crude timing showed a little faster. The wind was not strong but left to right did have a light head wind. I didn't expect 150+ with a Thunder Tiger but it was a lot faster then anything else at the field. This is the first TT that I have owned and at this point I would say it is a very good and strong engine for the money. I am sure a JettStream muffler would bring it to life.

Mike remember if you are going into a headwind you have to add that to your ground speed to come up with your airspeed. What I am saying is that your timed runs might be closer than you think. Also keep in mind your engine is still new and has a bit more time before it peaks out for performance. Oh yea a tuned pipe would help some say 10-15% more rpm I know in ducted fan units it make a big difference.

The airplane and engine are new and the best combination for max speed will take awhile to find. There are other things to test like trying to fold the wings which we have tried to do but couldn't Two carbon fiber spars probably wont let that happen. There were two dead sticks with one landing downwind into high weeds the first day with out damage. The one bad landing in the long video flipped the plane over and hit the rear of the elevon. There was no damage to the plane but it actually stripped two teeth off the servo gear. So far not even a hole in the covering. I now have the CG figured out and the engine is running great so flights have been uneventful. Testing both ends of the envelope have found no bad flight characteristics.

My prediction and hopes for speed
TT 46 with 8.75 x 8 is 120+ mph actual
TT 46 with 8.5 x 9 is 136 mph estimated
TT 46 with 8.25 x 10 is 151 mph estimated
TT 46 with 8.25 x 10 w/Jettstream is 165 mph estimated
Jett 60LX fire with 8.5 x 10 is 190+ estimated
OS 90 DF....Just kidding

I have a Dynamax 5.25 ducted fan, a OS 91DF, in flight remote mix and a JMP system II tuned tuned pipe; I wonder what you could get out of that.

I Built a six foot wing with dual carbon fiber spars I got it to flex a bit but not much...

I could not down load the large video myself ....
I just saw the short one

Gee I just happen to have a 60LX FIRE sitting on the bench looking for a home was thinking a clipped dust but this may work.

Mike Connor

Anyone else having trouble with the video? I had trouble myself right clicking and downloading but both let me just click them to view. The large one did take a little time to load.

I am uploading to YouTube now for those having trouble.. Should be done soon.

Video looks awsome looks like its just begging to have a 60LX in it.

That's what I was thinking. With the huge success of the test flights this week I am in the process of putting a few kits together for some people that have requested one plus a few extras. Between the laser cutters, plan printers, carbon fiber tubes and wood it is a lot of stuff to get together. It is kind of a low profit hobby thing for me and I will try to sell full kits less hardware for $69.95. I still need a couple of weeks to get things together.

Nice landings Mike. lol

After watching the first 15 seconds of the long video you will know why I had to fire my brother as camera man and take over. I was not the pilot of either landing but running the camera. The guy flying is a really good 3-D pilot but this was a little out of his element. At least there was no damage other then a servo.

iron eagel

You need a gunner from a b17 to keep up with that thing with a camera.

A delta does not land much like a 3d airplane and does take a bit of practice getting the hang of. I had a prop driven delta dart model that when you had to dead stick, was a real beast to land. The final landing attempt resulted in a ten foot long trail of balsa and silk to the engines final resting spot. I'll have to build another one of those some day with something bigger than a .20 for power.
Sounds like the engine temp is just about right if you can touch it at all after flight.
I wonder if you went with a tunned pipe for an exhaust if you pick up a few more rpm's and reduce the drag over the standard muffler. One of the members of our club had a .56 tunned pipe in a control line stunt plane that cranked and was fairly quiet to boot, you heard the prop sing right out nice on it, he is at the nats this week wonder how he is doing...
I can see from the video why you have gotten a lot of request for kits, flies like it is on rails from what I saw.

You got that right. I have had a lot of practice and I still have to pay attention.

Thanks SJ, West Coast? Hmmm, Sooner then you think.

Mike Connor

My Feedback: (5)

Everything is coming together quickly and I hope to be ready to ship a few kits by the end of next week. Those that expressed an interest via PM or in this thread will have first shot if you are still interested. Please visit my web site listed below and send me an order to show interest if you would like a kit. Do NOT send any money until I confirm a shipping date via email. The manual and a lot more info is on the site.

I cleaned up the dead spots on the video and added some more slow flight if you are interested.

I was looking at the side views on your site and I'm not sure a pipe will clear without a riser, I have the straight one piece header and pipe for my 60LX Fire I'm not sure it will clear the center section there may be more room than it appears though.

Mike Connor

My Feedback: (5)

Your exact setup is what I am considering for my second one. You must of overlooked on my site "The fuse area can be extended down to drop the fuel tank for easy rear exhaust installations." (see pic below) The top is only as high as you build it to clear your setup. It may take me awhile to start that project and I was hoping someone would put some serious power on one soon. If not You will see the video when it happens. [X(] It would be simple to build it like a Dust but I will leave that to someone else.

I have a brand new OS 1.08 in a box that needs the home. lol
I think I'd need a bit more wing on that one, although there is my OS 91df that could use a home, 20,000 rpm with a 8 pitch prop would be entertaining also.

Mike Connor

My Feedback: (5)

I thought about the OS 91df with a prop but with the rear intake it is over 5" long. Not going to fit on this bird without some redesigning. I will email you the plans so you can blow it up and scratch build a larger airplane if you like.

iron eagel

Thanks mike,
I think that with a 91 df it be way to fast for where I fly....
I bet that you could get 200+ out of that setup, even with a bigger airframe.
Just add the extension you have and a 60-70 would fit well and more than enough power. Hmm, make the center section an inch or two wider mount the engine sidewinder totally enclosed within the fuse. Pipe the exhaust and air to a rear dump bet that would honk.
