Sling TSi- Must-Have Upgrades!

[@pathdoc]

Evan, your building hacks and improvements are amazing. I've watched other Sling build videos and you are definitely building a superior airplane. I hope you are still doing build assists in a couple of years, when I hope to get a Sling.

[@foesfly3047]

This video is my introduction to you and your airplane. All I can say is, you have a very enviable setup there, from the high performance powerplant to inflight adjustable propeller to EarthX battery all in a very capable airframe. Seriously happy for you. And thanks for sharing your experience.

[@OneLiterPeter]

Please video your trip to Sun N Fun and back. I'm sure we'd all love to ride along! Cheers and have a good time.

[@JudgeEarl]

Most excellent! Thank you Evan for contributing.

[@azzamaddas4437]

Excellent video, wishing you a safe round trip. Hope to be able to meet you in future shows and events. I need to learn more about aviation from you on top of my 33 years as a professional Aeronautical Engineer.

[@rickhearn5899]

Have a safe and fun trip. It should be fun to show off your lovely new TSi!

[@flyingnp4924]

Safe trip. Wish I was going to SnF, but the kid has baseball starting this week. Have fun

[@JonMulveyGuitar]

Excellent upgrades! Great PSA. Have a great trip! Evan I sent an email a couple months back regarding the build contract and costs. If you are still in the build assist biz let me know! Cheers, Jon

[@Hajduk12]

Excellent video.

[@YourFriendlyGApilot]

Wonderful video, thank you.

[@rvingjetpilot5302]

I wish I had seen this earlier. I was at sun and fun too. I would have loved to see your plane.

[@john9663]

Evan: How did you determine the fittings were undersized? Great solution. Hopefully, you will post something from your trip to SUN n FUN experience. Blue skies on your cross-country trip.

[@EdwardHefter]

Thanks as always, Evan. General builder question for you (or other people watching your videos) - I’ve seen your comments on brakes and fuel lines, and other people’s comments on cabin lighting and other changes they recommend. I am just getting started on the empennage. What’s a good way to keep track of all the recommendations that pop up here and there? White board where I’m building with the notes on them? Evernote? Hand written notes in the Sling drawings?

[@EvanBrunye]

Whatever works best for you should be great

[@EdwardHefter]

Decided on Evernote, which is also a good place to put wiring info (which color connects to which color) and what other things still need to get done.

[@H60ace]

Those are good looking brakes. I was into the Berringer brakes, but these are about 8% of the cost of those. Do you have differential (toe) brakes?

[@LifeLatitudes]

Hey Evan, thanks for sharing your experience. I have got 3/8 hoses but an old/small fuel selector. Sling is informed and i wait for an answer. What about the boost pump (located in the center console)? It is a small one in my kit. The inner diameter of the fitting is: 0,234 inches. Its is really narrow and seems like an old or small one.

[@EvanBrunye]

My personal tsi doesn’t have a boost pump, and works fine with some special tweaks. The boost pumps the factory supplies have 1/8”npt fittings, so yours is the correct one

[@LifeLatitudes]

@@EvanBrunye thanks a lot.

[@louweinberg8999]

Thanks Evan. Great video. Do you know how much weight your new brakes add vs stock brakes? I’ve got about 50 hours on my TSi. I have the new fuel system spec including the auxiliary fuel pump (that we set up to come on with pump 2). I did all phase 1 in So Cal (warmer than ID). Been up to 12,500’ no fuel pressure problem whatsoever running only on pump 1. Have my O2 system now. Will take it higher soon. Enjoy your flight to Sun n Fun!

[@EvanBrunye]

They add about 1.5lbs each side, not a big deal and well worth it in my opinion. I’m not a fan of the aux pump, and will be working diligently to come up with a more proper solution

[@cyrusn6299]

You've mentioned in this video, and in a few other places that the fuel lines from the selector forward should be swapped out, but I'm going to be starting to build tanks in a few weeks, would you have swapped out the fittings in the wings as well if you had the chance? Thanks for the video, can't wait to chat at Sun n Fun!

[@LifeLatitudes]

Thanks for sharing. I wonder if you can reduce the taxispeed by feather the airmaster manually to a smaller amount of pitch during taxi operation? I love all your vids 👍🏻 cant wait to get my own one.

[@EvanBrunye]

Unfortunately not. The prop automatically goes to the finest setting at idle because no matter what position you have selected it’s trying to get the engine up above 5400rpm

[@marcusconner5251]

Thanks for the answer I asked the same prior to making it this far down in the comments.

[@benthurber5363]

@@EvanBrunye How??? You have an Airmaster setup, right? The control should have a manual override switch and you can control the pitch.

[@EvanBrunye]

@@benthurber5363 yeah but there’s a lot more to the prop than that… for this specific situation there are mechanical stops to not allow the blades to go beyond their set point for fine and coarse. They get adjusted but you can only go so far before other concerns are more important.

[@aavanhoff]

Excellent info, thanks. Can you share the part numbers for the MatCo brake parts?

[@EvanBrunye]

Contact [e-mail]

[@H60ace]

Are your plane accents wrapped or painted? It looks great.

[@bradmarlin2964]

Safe Flight - Cheers!

[@0897728232]

Hi Evan, great tip’s. I like to upgrade to the Matco brakes on my TSi, do you have the part numbers of the disc and pad kit you used?

[@NotTelling51]

Been wondering where you were...

[@dvsmotions]

It's going to be nasty here this week.

[@marcusconner5251]

Evan, could you manually change prop pitch for better taxi speeds?

[@EvanBrunye]

Unfortunately that doesn’t work

[@marcusconner5251]

@@EvanBrunye Thanks for the replay. Saw you had already addressed this after I committed. Your plane looks great man. Have a safe trip.

[@alexisrovira4235]

Hi Evan , How much more does the new brake kit weigh?

[@alexisrovira4235]

I already saw in the answers below

[@TridentCapital]

Does changing the fuel lines reduce the fuel efficiency (i.e. increase the GPH burn)?

[@EvanBrunye]

No, that’s all dictated by the engines ecu

[@richardseton7014]

Will TAF allow this upgrade as a "Certified" upgrade, from a factory built Sling?

[@EvanBrunye]

What do you mean? These planes are experimental, the best part about them!

[@H60ace]

@@EvanBrunye I believe he is referring to the RTF version of the plane. That thing isn’t sold in North America.

[@aggibson74]

can you change the prop angle to help with taxi speed?

[@EvanBrunye]

Nope unfortunately that’s not how it works

[@SgtHulka_III]

If a Sling were to flip onto its roof during a landing how can you get out?

[@chriskroeker1889]

So the pants work just fine with the new brakes?

[@EvanBrunye]

Yup! No change to the size of the wheel or area surrounding it

[@WingtipstudioCA]

Hi Evan, thanks for sharing your findings. Would you be able to share the break upgrade part #?

[@EvanBrunye]

They don’t have a part number as far as I know, I’m the first to receive this upgrade. Email [e-mail] for more info

[@suzukirider9030]

Quite surprised that a 1/4" tube is insufficient to just let the fuel flow. I mean it only burnds like 10 gph at full throttle? one would think a 1/4" tube would be plenty for that. Esp. considering gasoline flows a bit faster than water.

[@SgtHulka_III]

where is the Kitfox?

[@EvanBrunye]

Coming soon!

[@ibgarrett]

Well... I WAS going to go to sleep... but I got time to get this in... :)

[@claudepignol3573]

The upgrade of the fuel line size doesn’t make sense.

[@EvanBrunye]

Why?

[@feidelsol]

👍

[@austinholt6027]

Has the aircraft been damaged at the front

[@EvanBrunye]

No

[@miker2827]

What production Number is your plane.

[@EvanBrunye]

206

[@miker2827]

@@EvanBrunye thanks. Mine is 207. Also have pressure problems.

[@jagitmax]

2000 rpm idle ? should be about 800 rpm

[@EvanBrunye]

Definitely not
