Sounds like I'm in the same boat. I'm looking at getting back into the hobby after over 5 years and have no idea what help to get. I used to ha e a  trec600, raptor 50 and synergy n5. Looking forward to see everyone's recommendations as it looks like the sport has changed a lot!!!

Here is a translate of a post Jan Henseleit made on a german forum.......

Dear pilots, speed  the rotor live is gone, so that I now a few minutes found time also here in the Forum to announce a few data and background information on the new TDS-FAI, to clarify some technical and general questions. 

First I anticipates will, that I am even surprised that it, worked at all by that early date to finish the prototype of this machine airworthy because I myself only wrestled through mid-January, before 8 weeks, at all to go on this project up again.  As perhaps the one or other still white, I presented the original version of the TDS with the high set tail rotor in the profiled vertical stabilizer and the fuselage at an angle inclined to 8° at that time as a 3-leaf version already on the rotor live 2013, but in this version never to the Made ready for series production.  As there were various technical problems with the 3-bladed rotor and also focus on problems caused by the tail at the time this novel project, I had derived the TDR-II in a trainer version of the TDS mechanics to a wider audience in the 700 up 800 Class to speak, that fly 3D wanted both speeden.  With the optional closed speed hood, a race bread has evolved from this, with which we at least keep the current speed world record.  So when the 300km / h around which real limit is reached, where still fairly reasonable effort to bring is something, I put the development of the pure speed machine TDS in the former shape files.

The at that time still in force 6kg as an upper limit for official recognition was not to reach, while it barely worked on the TDR-II with the TDS.  Sorry, that I have brought the then announced conversion kit with the TDS rear not for series production but the focus problems in the handle to get the necessity of additional lead in the top of the hood, then I'm up to a take-off weight not under 6, 4 kg come, again speaks my demands on myself.  I only then put a product on the market, if I am 100% convinced even at the moment of completion and have fun doing it. That was not the case in the original version of TDS, even though the basic concept and the aerodynamic solution has always liked.  Now the bird hung for many years with me in the workshop on the ceiling and each time, when I pass went off, it has me annoyed, that he in principle so flew, but not in my mind.  Now still a shock, and what is worse to introduce the 10s as voltage limit, without came anyone from the scene, then in the last year because any unsuspecting creatures at the FAI concocted, to lower just the weight limit on only 5 kg of It knows, to ask. 

A great way that only prospect extremely one small click of crazy enthusiasts completely flat to trample.  Well, anyway, encouraged this action of course hardly a manufacturer to undertake anything in this direction, because the market for such a niche product itself worldwide as small is, that it is economically worthwhile in any way.  It was now the success that some hobbyists have begun to make a Swiss cheese to scrape down everywhere a few gram from the TDR-II. This possibility offers but only very few and the danger that with insufficient experience precisely the opposite happens, what probably was thinking of the FAI from safety-related aspects.  The material is ever quite close to the limit for this sport and the danger that dozen people build something, then fly apart in the air is relatively large, although I can understand that the tinkering is in itself Yes a beautiful thing and again more classic fashion llbauerfähigkeiten are needed.  As manufacturer, but has the problem that no one from the outside sees what there under a TDR II hood most Potter is and if so a bird very spectacularly in public, at almost 300 km / h in the air burst, it is then called As are a total 150 g, which is flat by omitting the linear steering and the use of the perfectly appropriate, but still extremely strong and MKS-HBL575 SL - servos, a really big post, can save, the fast and easy is reached. 

The servos are as it were constructive component of the overall concept. I would have achieved but also rather linear linkage, but let it get weight - neither in terms of space.  Because the machine exclusively for the game or large flies and in any way for any form of foraging zappelns is designed, this is also a serious disadvantage for me. I have designed the Anlenkgeometrie that is as good as no angle distortion at maximum pitch and additional cyclical swings.  In contrast to the TDR-II for the 3D a rash of +/-15° + 10 ° has cyclically to reach are the TDS only +/-12° scheduled. So an optimal from the experiences of the last years angle range for high-speed helicopter from - 7° to + 17 ° is achieved by an offset of Blattgriffanlenkarme 5 °, move is of course slightly in both directions. The 7 ° sufficient loose for a car safety Rotary from every position and also for short passages of inverted flight when turning over or elongated rolls.  Also I have dispensed with this machine on the rotating tail rotor (optionally he can but realize) as you will conduct determined no auto rotation exercises for fun with this machine because of the thin land feet. The fin is the stern for easier moving forward automatically keep aligned, so that the Auto rotate easily only via the cyclic control to the desired landing site can be. Also the in addition car rotation energy gained due to the missing rear belt friction is substantial. 

Another reason for this design, I saw in the advantage of the former Bemerkens of motor failure, because the tail rotor as the loudest noise source, also no longer at the moment where the engine is.  The tail rotor gear was lowered in contrast to the TDR-II by almost 20%, so that the tail rotor adapted not to high turns the high speeds of the rotor head. The TDR-II that was actually way too much due to the necessary 3D-Tauglichkeit not so and thus to the game. This is also the reason for the very pleasant noise of the TDS in the high-speed flight.  To the arrangement and design of gearbox stages, the following is to say. Main problem of the original TDS was the observe this, which was caused by the length of the tail pipe. They left out but not without another, because there are unfortunately no fine gradation in the field of used heavy-duty timing belts in the required length. He next smaller possible timing belt in this class would be shortened to 300 mm and thus would shorten the tail whole 150 mm.  The other arrangement of the intermediate shaft from the rotor shaft and not between the motor and rotor shaft as the TDR II, could I on the one hand push the engine a little further forward, but what was most effective, move forward the complete tail boom to 75 mm.  Nevertheless, still blade lengths are fliegbar up to 720 mm.  Therefore, the first stage, where the torque is not too high, was now designed as belt drive in to go from back to front. Entire rear part of the chassis could be reduced significantly. The hood, rear had contact with the chassis during the first TDS version and was therefore down never to close, has now sufficient space at the rear.

Part 2 

Still a few comment on the cable-laying. Of course, no extra trunk for luggage and huge cable channels is intended for this impact speed machine. In the formula 1 car, there is also no glove box. However, the servo cables to the motor is gone, like the prototypes on the existing photos due only shortage of time.  Can the cable be together very nicely so, that they are made before the oblique attached Nicksevo down and then led back below the motor.  Who has no Flybarlesssystem with receiver in a housing, can install it underneath the top of the Flybarlesssystem. The antenna lead from the carbon hood also is also very easy for the selected position behind the engine.  The rotor blade grips is to say that they through the gaps although as TDF hand grips look, but in reality of cross section and inner workings here of course are TDR-II blade grips. 

The thrust bearing of the TDF would not join these burdens.  I have this time produced the main gear not peek but again Delrin. The main reason for the choice of the Peek material was then mainly in the lower thermal expansion. The procedure to customize the gear with distinct undersize and to shrink, which I introduced in the TDF, solved this problem as well as the TDS. Delrin is rather better than peek from the sliding qualities here.  There are still many details that you could explain, but I hope to have contributed to clarifying the basic surfaced questions.  The sale price of the TDS Kit is calculated with 2500,-what is due to the low expected quantity and the infeasible very elaborate tail boom with the integrated rear rotor.  The model is made in small series with serial numbers according to the incoming orders and the completion of the first batch is scheduled for August of this year.  Greetings Jan Hamilton

Thanks for the Feedback guys....

Ralph, with the provider I use it's about $200 a year for my Forum. This could be a little more with the size of the database arcHELI has!
