TDR II and TDS at IRCHA 2014

[abanihani]

Hello TDR fans, I was lucky enough this year to attend IRCHA and get the privilege to see first hand the upcoming Jan's master creation of the TDRII and TDS. I must say that Jan and team Henseleit were so pleasant and i thank specially Oliver and Richard for outstanding representation on this great team. I had lengthy discussions and will summarize what i got to know so far about the models:
- There will be only two models, TDRII which can be a 3D and a speed trainer, at the same time, and TDS which will be the dedicated speed machine with full fuselage. TDRII will have either the retracts operated by a mini-servo or regular landing gears as seen in the photos below.
- Release is delayed until next year as Jan has been experiencing resonance above 2600 rpm only which resulted in loss of 4 TDRIIs so far. He can't pinpoint the source at that head speed so he is conducting more testing with some help from an engineer from the university to do vibe analysis to figure out the source. This obviously will take some time and delay the release until it is 100% safe to fly. I really admire Jan not only as a great designer but also for his honesty as not many in the industry confess to problems in their design and release the new models and have customers report back issues, so Kodos to Jan, my respect to him only increased .
- Jan told me that he will not fly the model at IRCHA for safety reasons but on the last day, he sneaked out with Oliver to site #3 (the speed tract) and flew two runs at 2550 rpm. I was lucky enough to witness this test as i was at the right time and right place when this test flight occurred . The heli was so damn fast and what impressed me more was how quiet it flew. I have owned a Banshee and i can say with confidence that the new TDR is way quieter than the screaming Banshee at these high head speeds. I can't forget the priceless smile and dance after this test flight by Jan and Oliver and yes it came down in one piece

- TDS will be released way after TDRII, they share the same mechanics except for one piece that diverts the tail 90 degrees to the fin as seen in the photo below.
- In term of size, it is as slim as the Banshee even with batteries mounted upfront. Oliver said that it is around 6 Kg with 14S 4400mah and three head blades (x-blades) but will be around 5 Kg with 12S and two blades.
- Canopy is very easy to install like the current TDR model but Jan has not finalized the installation as he has other things to focus on, he is using tape for now to hold the rear of canopy to the boom until this part is finalized.
- The mechanics are tight in the frames, however, by removing one side of the frame, it is easy to get to all the first and second stage to work/exchange, etc.
- Obviously to all, both new models have belt driven tail
- Jan is using the AC3x system made by acrobats to eliminate the built in expo and have linear servo movements but he assured me that most FBL units will work including the vbar. He talked with Olli specifically about that and was informed it is very easy to do and they will help out when release is coming.
- These are some of the photos i took, i do apologize for quality, enjoy:



Notice that he is using a buffer back but continues to use exclusively the KOSMIK BEC







Optional 3 blade head, the dampening is adjustable to suit your flying style

Beefy secondary gear, heat resistant



First stage gear, similar to the current TDR, I forgot to ask if he can produce in black color



This shows the rod for the servo mechanics





Detachable battery tray made from carbon fiber, the circular latch you see in the photo controls the 1 second release of the tray, you can buy few for quick battery exchanges



This is the piece needed to divert the tail 90 degrees to the fin in the TDS version with full fuselage



Notice the two bulleys, it allows the belt to go towards the main mechanics and then back to the tail, genius

Finally this is for regular landing gear if you don't want the retracts

Great pics and oh yes drooling...... Thanks for sharing

With regards to the Kos 200HV, how are the Kos's front two mounting lugs attached?

In the pics, it looks as if the Kos is just hanging on by the back two mounting lugs.

BTW, nice pics.

Wow...great to see some new photos. Thanks very much for posting. I sent my email to Jan yesterday to get on the list for the TDR II. I'm probably number 5000 at this point, LOL. But by the looks of these photos, it will be oh so worth the wait.

You are correct, only two attached as in the photo, Jan's intention to use these as sacrificial point to eject the kosmik and avoid damage in case of a crash.

My understanding this list is now 400 +

That is an amazingly compact drivetrain!

I'll definitely get a set of regular landing gear as well as retracts and set it up simply and then the retracts once I'm comfortable with it.

So I'm curious for those of you on the list to get one....

Are most of you just going to put the end game most powerful motor in there and start with 12S and then go to 14S when you want to see it scream ?

Or do some of you have a series of motors that you are going to work through?

It looks like the TDR-II / TDS are almost guaranteed Kosmik 200HV sales because of how they fit.

From pictures it seems that there is back non-DFC head with seesaw. Will it be possible to modify wobble head to stiff head as on TDR?

I'd imagine that alternate esc mounting plates will be made in time, as not everyone will want to run a Kosmik. Plus it looks like a relatively simple matter of making a cf plate...


I wonder what the average flight times will be if everyone ends up running monster 14s Pyro 850 setups.

[mkovalcson]

I was just looking at that "see saw" as you called it.

It's pretty interesting and low profile as well.

Another new design I've not seen before.

I suspect the non-DFC 2 bladed head will have all the flexibility of the existing head. We'll have to see what options there are for dampers etc..

[mkovalcson]

I am very curious what kind of ball link pliers are required to get the main links inside the swash on and off. It also looks like they will need to be connected before the swash is lowered on the main shaft since there will be no way to reach them except from underneath.

Very nice, abanihani! Thanks for sharing!


One question, if you can answer. Was this the heli that he flew? If so, where was he hiding the FBL? Looks like that might be it under the two front servos and buffer pack.

Of course the Dry Fluid lubricants are white.
I think I will leave the gears alone on this heli.

Thanks also for sharing the photos. I like the special edition "Jan Henseleit" motor among other things. Did you get any video of the test flight?

Unfortunately not, i was in a remote area practicing when someone approached me from the back saying they are testing a prototype and i have to land. To my surprise was Jan spooling his TDR II that he said he won't fly it at IRCHA. He did only two passes, landed and went back to the booth. My camera was not with me at the moment

[marcosp]

German secret service would have confiscated the camera if you had shot anything...

[swalko]

Seesaw is a part of rotor head inside main rotor hub. RI-0140a . I dont like wobble/rocker head so i hope that it will be possible to change inserts RI-0109 to stiffer variant .

Not buying that rationale....

No offense, but that's BS

The Kosmik looks like a brick but it isn´t. For a crash it makes no difference if it mounted on two or on four points.In the Diabolo S it is mounted in the same way (turnable, with loose front and removed eyelets) and we already made this experience.
