We have had a few requests for a video discussing how to properly setup the geometry on your throttle servo. In this video Jason covers this topic on our 91" Extreme Flight Yak.
As always, we hope this helps in some way. Please be sure to share with your friends via social networks to help us reach as many people as possible.

I’ve learned a lot from your videos but I think a lot of guys take a different approach on throttle setup. The Walbro carbs on most gas engines are super sensitive at low throttle and not at all sensitive at high throttle. You can get much more linear throttle response by setting up the servo arm so it points almost directly towards the throttle arm at idle, and using the shortest servo arm possible that still gives full range of operating RPM

Love the closeups of your hairy paws.

So glad you enjoyed them. This was market research for our new website, www.onlyhairypaws.com. LOL

Great video and thank you for making it. I didn't notice that you mentioned the orientation of the throttle butterfly needing to be placed half open/closed only the servo arm. I thought both were important to be half open/closed before connecting the linkage. Was under the impression this was very important in order to get the proper geometry. Maybe I learned something new. Thanks again and look forward to seeing more videos in the future.

@FlightReviewz 4 года назад

Thank you for the feedback, Hank. When I am talking about the movement of the push rod lining up with the servo opening I am setting it so the butterfly is half open when in the center of the servo opening. I should have been more clear on this and will be sure to cover it on another plane to try to add some clarification.

@@FlightReviewz Thanks guys, I really enjoy your videos and even after some 40 years in this hobby, I still find things to learn and apply in my flying. I guess your never to old to learn new or better ways of doing things. I look forward to seeing a video covering baffelling which I requested some time ago. I know there are many different ways of doing this but I am interested in seeing how you suggest it should be accomplished. Again, thanks for your time and efforts in making our hobby enjoyable.

Get yourself a good gyroscopic screwdriver (DEWALT DCF680N2) and long hex bits and you'll save so much time putting servo screws in and taking prop bolts off. Simple to use and I've never stripped anything with it. Lot easier on the hands too.

@FlightReviewz 4 года назад

Thanks Don. I do have a really nice Ryobi Tech 4 screw driver that I use in conjunction with MPI bits when assembling planes at the field. I do prefer using a hand driver when building to avoid stripping fresh wood.

@johnmueller8462 4 года назад

Hi Jason have finished your Yak .Hope all is well with you and your family

@sendit2873 3 года назад

I also use hardwood pieces under the servo so the screws have plenty of wood to bite but why not use a threaded almn. arm looks like the standard arm threaded would not hold up

@FlightReviewz 3 года назад

Thank you for the comment @send it. The engine is the source of all vibration in our airframes. For this reason, we prefer to use a nylon arm with a threaded hole. Jason's competition IMAC plane has over 1500 flights on it with this setup and he has had no issues.

@franciscourena5636 3 года назад

** Great Presentation. How you considered converting the RC plane into an UAV? making it autonomous flight with Pixhawk flight controller?

@FlightReviewz 3 года назад

Not with this plane. We do know people that have done this with smaller foam planes. Definitely looks like fun.

How do I trim the turbo timber to fly straight when taking off?

@FlightReviewz 4 года назад

We had no trim issues with our Turbo Timber. As long as the AS3X is active you should have no issues. Make sure the surfaces are all centered when the trims are centered by adjusting the lengths of the push rods if you have any issues.

@Kraftei Год назад

Hi Jason, good job, nice video! I noticed that you used the servo screws without these rubber grommets, that normally come with the servo, right? However you seem to use a verry smart, dumping enginge mount (is there something similar also for the DA50R?) these rubber grommets could reduce the risk to get your servo electronic damaged due to vibrations isn't it? So far i was only into electric powered planes and turbine jets, so vibrations haven't been an issue, but now, as i build (restore) a 33% pitts, powered with a gas engine (as said, a DA50), I fear these vibrations! A throttle servo, stuck in full throttle isn't something one wants 🙂 Or is the posive effect of these groomets overrated? Greetings from Germany 🙂 Holger

@FlightReviewz Год назад

Holger, Thank you for the comment. The motor mount is a Blazing Star mount purchased from Northwest RC. There is no dampening on this mount. As for the grommets on the servos, The rubber grommets are there and the metal eyelets are installed from the bottom as they are intended. This causes the head of the screw and the bottom of the grommet to be isolated by the rubber in between. This causes the dampening effect you are referring to. I tighten them up and then back them off an eighth to a quarter of a turn. This helps lengthen the life of the servos. Hope this helps. If you have any further questions don't hesitate to ask. Jason

@Kraftei Год назад

@@FlightReviewz Thanks for explanation! Didnt see the grommets - only black 🙂 Keep up our good work! Learned a lot! Greetings from Germany :-)

Are you using your JR radio in this plane

@FlightReviewz 4 года назад

Yes sir. I will be using the T14 on this plane.

What reciver are you using in the Yak

@AustinPetDetective Год назад

That easy, that quick. It’s not that easy or quick, one of the hardest things to do.

@FlightReviewz Год назад

Might be one of the hardest things to do with our modern ARF models, but definitely not in the top 10 hardest things we have experienced in the hobby.

@WadoF22 3 года назад

Nice video..new sub here..thx.. What servo driver is that you use ..very useful 👌

@FlightReviewz 3 года назад

Ed, the servo driver we are using is a JR Matchmaker. They are hard to find these days. However, Spektrum and JR still make similar devices. We may try to review a few of the available options in the future.
