14 SG door sequencing with Robart electric retracts
Henning Strand replied to Henning Strand's topic in Futaba
Thanks again, Malcolm. Appreciate your dedication and love for Futaba. I too am a Futaba guy at heart, never straying away from the 'chosen path'. That is also why I expect a lot from them and of this radio. I know that Futaba do not say that it has a sequencer, and thus I am happy that the work around is possible. That being said, I am sure that adding a sequencer functionality linking two or more functions, with the possibility of defining timings between them, would be useful for many. (Undercarriage/doors/landing light); bomb doors/bomb drop; ...) If Futaba are listening - just my two cents. At least for us scale guys this would be very useful. On the topic of separate dedicated sequencers, I actually did buy the EMS sequencer recommended to me by Robart. That did not do a lot of good, though. The main issue with the electric retracts is that they do not behave like normal servos where the cycle times correspond with the speed defined by the radio system. They simply take the time that they need, defined by the input voltage. More volts, faster cycle times. When using a 6V battery they take around 12 seconds. The EMS sequencer does not have the capacity to wait that long before triggering the doors. So much for trying out the recommended way. -
14 SG door sequencing with Robart electric retracts
Henning Strand replied to Henning Strand's topic in Futaba
Thanks Malcolm. Spent some time this evening going over my settings. What surprised me is the big difference in speed only a slight change of the In and Out speed settings make. I got it working by slowing down just one step, but that actually made it way too slow, so I had to change the door point curve to move the action of the doors nearer to the gear cycle. Otherwise there was a big pause between the two. One odd thing about the Robart gear is that it starts at 13% on the point curve, so if starting at 0 the cycling does not start immediately after flicking switch. Finding that out was simply a trial and error job. See pictures of my setup in my album: **LINK** Not really too user friendly this. Would have liked Futaba to add better ways of connecting functions, setting the times between them, and the actual time needed for the movement to complete. OK, so it works - but it's more of a work around than a proper sequencing functionality. -

I am also using Malcolm Holt's great book to set up my sequencing. The problem I'm facing is that the Robart electric rotating retracts for my 1/5 Corsair take about 12 seconds to fully cycle (6V battery). I am finding no ways to configure the program mixes so that the door servos will wait for this long until they start closing. I would think I am not the only one to use a 14 SG with Robart electrics + gear doors. Please provide tips on how to get this to work. Thanks

Please share ideas and tips on what material to use and how to construct.The doors themselves are finished, created from layering glass cloth and epoxy. It's the insides of the doors I haven't yet decided on how to make. http://www.ratomodeling.com/references/f4u_bu17995/target26.html http://www.ratomodeling.com/references/f4u_bu17995/target25.html Thanks!

Gear & door sequencing - what Tx?
Henning Strand replied to Henning Strand's topic in General Radio Discussion
Thanks for all your input. This forum is truly one of the best! Lots of passionate and sharing fellow hobbyists. And folks, it's not about not believing in the Taranis products or brand, it's about not knowing - hence my follow up question earlier. Based on your truly believable feedback I might very well end up with Taranis myself, and in due time become a die hard supporter like the rest of you. -
Gear & door sequencing - what Tx?
Henning Strand replied to Henning Strand's topic in General Radio Discussion
Taranis is indeed interesting, but a little scary for a lifelong Futaba owner. Would you all trust it in your 500 hour build? -
I am looking for a new transmitter for my big scale warbirds. Have been using a Futaba 7C for some time, so have a few receivers. Being able to reuse these is of course favourable, but not a must. I want a radio with at least 10 channels, telemetry and lots of mixes and options. I want to not have to add a separate sequencer unit for gear and door setup, so I should be able to both adjust servo speed and sequence timing through the Tx. Upgradeability is also important to me, I want to buy a Tx that won't be out of date the day I buy it. Price is of course relevant. I'd like to keep it below £500 if possible. So, what would be the best option? Thanks for any input! Edited By Henning Strand on 26/02/2015 19:11:59
