    TDR Component options.

    Hello all,

    i have been flying flybarred Nitro 90% of the time and a few small electrics (250 / 450) and have now purchased a TDR to try something different.

    As the TDR is a completely different animal for me (flybarless and big leccy) I could do with some recommendations to complement the information already provided by Jan on his website. I have opted for the Futaba BLS251 and 451 servos i have some DSM2 receivers waiting to go into this bird and have a free reign on what else goes into the package.

    I do have a few questions.

    1. Would I notice the difference between the Kontronik jive 80 and 120 ESCs (am planning on running the Pyro 700-52 on a 12S setup). I think with the uk temps I could get away with the 80 and a heat sink as I am no 3D hero and prefer big air style flying. Does this sound sensible or is it a false economy? Are there any other motor recommendations I should consider?

    2. I have a datapod and have Spartan gyros in nearly all my helis and I was thinking of going with the Vortex over the Vbar blue line express. Are there any compelling reasons not to go with the VX1?

    3. Does using the jive BEC make sense with this setup?

    Many thanks for any advice you chaps can provide.

    The beauty of running with Jan's recommended setup is that his manual is focused around this, he tells you which servo horns to use, which hole etc etc etc. So the build is easily one of the easiest, albeit you spend a lot more time reading it.

    I believe a Jive 80 will be okay for non-uber fast setups using big motors.

    Vbar / Vortex, upto you. Although the vbar s/w has indicators for the TDR so quite easy to get your initial settings right - except for me, as i'm a retard

      I went for totally standard Jans set up , could not be happier !!!
      I would sugest Helijive 120 as it has auto bailout and I use mode 6 for lower head speeds on gov setting , also more headroom.
      On H*lifr*ak some of the guys have Jlogger and you will be suprised at the amp draw on big air moves and fast big loops etc (it will encorage sutch flying)
      I have 1430 rpm normal 1650 rpm idle 1, 1830 idle 2,
      standard set up I use Helijive bec with no problems at all.
      With 4000 mah Turnegy 40 c packs all up weight is just 4 kilo's .
      puts a silly grin on my face every time I fly it

        By the sounds of it the Jive 80 with a heatsink will be more than fine and with that motor which is very efficient you should see no issues. However the Helijive would be the preferred ESC for many. I always use the Jive BEC as it is solid. As for the FBL unit, either as they are both great units.

          My TDR has the same servos and the Kontronic 80HV ESC driving the 700-45 Motor. No problems flying here in Spain.
          Been there and done that, but never stop learning.
          Now too many Helis to mention?

            Rather then the BLS251 on the tail go for the BLS256, it's HV and runs great on 6v so you don't need a separate step down reg for the tail.

            BLS451's are just great in any heli.

              i have 251's on 8 heli's at the moment, been using them for the last 4 yrs, probally on 16 differant heli's over the years and never used a step down, never had one single problem ever, i wish Futaba would change the spec and stop trying to cover them selves as this clearly works on 6v.

                They did list them as capable of running 6v a couple of years back I think. Tom Burgess posted the link which also stated 451's could run at 8v. The link is dead now but it wasnt for a long time.

                I cant find the thread no more but it was titled BLS @ 8v ok or something.

                  Hi All,

                  Many thanks for all of your suggestions and recommendations.

                  Am now erring on the side of the Helijive 120HV as it gives me more options in the long run.

                  Will go with the Spartan Vortex I think as I have always been more than happy with the Spartan products and support and from the recent reviews it looks very promising.

                  Now I just need to choose some Lipos (Turnigy Nano probably) a charger (Hyperion) and a generator (kippor sine master looks like an option) for field use. This transition to big electrics ain't cheap!

                  Cheers,

                    Would not bother with nano's have not had many cycles before puffing and loosing punch ! , I have got these ,
                    Turnigy 4000mAh 6S 40C Lipo Pack
                    and just got a pair of Gens Ace 4000 30c to try .
                    I keep them as pairs but also use them as singles in my Logo 500.
                    I have 2 Futaba 251 bls servos on 6 volts no problems at all.

                      Where Did you you get the Gens Ace cells? These seem to be quite popular with the TDR crowd looking at the setups on the Henseleit website.

                        Hi Laserfish,


                        What flight times do you get with the Turnigy cells (and at what headspeed)?


                        The Turnigy look to be a very good compromise of spec vs price) not the ultimate spec granted but should be ok for my flying style and abilities. I have seen other cells (such as the nanos etc) with higher specs, but do you think that this is overkill on my proposed setup?


                        Looking at the reviews on the site and the price it seems mad not to give them a try.




                        Cheers,

                          Trying to get GensAces is like trying to get blood from a stone - great batteries but always out of stock. I'm currently using Zippy 4000mah in 12s form and they are working a treat. You will love the flight times you get from the TDR. I did an initial flight for 5 minutes @ 1320 HS nothing agressive - bit of inverted a few flips and only used 30%. Even at 1320 HS its no slouch

                            My Maiden with Turnigy 30C 5000mah was 7 minutes at 1350HS and 60% use.

                            Now too many Helis to mention?

                              Had nanotec only last 15 cycles before visibly puffing and a significant sag in power very dissapionted. I have 3 and 6 s 30-50c 35-70c and 45-90 c pacaks all seem to be good for the first 5-10 cycles the go down hill fast?
                              Turnigy pale blue 40 c have had 40+ cycles and still no puffing and still have good punch!
                              Only had the Gens Ace for 8 cycles each seem to be getting stronger (never had that before)!
                              I run the TDR at 1830 for 5 mins and put 60% back in I will up the time to 6 .50 mins and report back.
                              I got the Gens Acs from ElectriFlyer Chris now supplies Haiyin have not tried them yet but will be ordering some soon.
                              I also use the same packs in my Logo 500 for 6 mins and put 70% back .
                              Hope this helps,
                              ps I only do big air 8 and stall turns etc but sometimes BPGOA gives it a ringing out 3D piroflips tick tocks etc 5 mins 65 t0 70%
