Good work Clint and Anna. Your cake-decorating and also your painting skills have been put to good use Anna. It's great to watch it being done, step by step.

@lalehbryanskrenes5692 Год назад

Doing great work, Clint! Thanks for sharing. Very informative and helpful!

@Vanblade1692 Год назад

Great channel. Just found and will follow. I might have some topics as well but in the mean time. Happy building

@argus5323 Год назад

nice job with all the progress! I know you probably feel like you dont know what you are doing when you are building this but it would really be nice to see you doing all this this work in the videos. I know its a lot of work but i enjoy watching planes being built and i to want to build one of these... ill probably do a XL model but i like everything you have planed out for yours, cant wait to see the finish and first flight bits.

@AusVelocity Год назад

Thanks, I'll have a think about filming while building and see if I can get the wife to film some stuff. I'd like to make it work. So far, most of the technical work is just measuring, cutting, drilling and glassing.

@lcprivatepilot1969 Год назад

Very interesting. Subscribed.

@outlawflyer7868 Год назад

Just found your channel. you never showed us how you got he twist out. Could you show us what the total cost was for everything?

@1deepsouthtejas Год назад

making progress, ours has 20 hours flown off, wonderful project

@AusVelocity Год назад

Sure is a wonderful project. I don't mind every minute I work on it.

@electricaviationchannelvid7863 Год назад

Nice progress video. Thx! The more details the better. Would you show sometimes the plans/instructions?

@AusVelocity Год назад

Yes, I'll try and work some of the manual into some videos. see how I go.

@TheOddVideoChannel Год назад

Might be a bit late but anyway: you could consider a magnetic field angle sensor (like the MLX90316). You then only have to glue a magnet near the rotation point of the speed brake and position the sensor near (but inline with) it. This way it is impossible for your measuring device to interfere with your actuators. This chip can be configured to give an easy to use 0 to 5V output (or PWM, or SPI). I have used these in the past to measure all control inputs of a helicopter, without risking to block some controls if a potentiometer would get stuck or something like that.

@AusVelocity Год назад

This is a great idea. I've looked at using them, particularly the KMZ41 for a future mini project on the velocity. I'll have to look at the MLX90316 to see if it's better suited. I'm a little unsure about the mechanics of getting a magnet to sit stationary on top of chip while the brake is moving. getting near the hinge is tricky, but i'd like to get rid of the potentiometer for one of these for reliability and better accuracy.

@TheOddVideoChannel Год назад

@@AusVelocity These sensors do still work when the alignment isn't perfect, but with an error in the measured angle. If I remember correctly, the MLX can compensate for this. Otherwise, you could use a microcontroller with a manually determined look-up table to compensate. I think you might get away with the magnet being just next to the hinge, but that requires a small experiment. In any case, I think in your case the exact angle is not super critical.

Quick questions, is yours fixed gear and what horsepower engine you considering with Viking ? I’m tempted to build this thing, but I’ve never built anything in my life not to mention using epoxy.

@AusVelocity 5 месяцев назад

Using the 195Hp. This was my first time with epoxy too. It's not hard. All the epoxy and glass is supplied. The tricky bit will be measuring twice and cutting once, then letting the glue dry. But remember it's not just 195Hp as compared to the 180-200HP Lycombing that's intended for the SE. the 195T maintains power at altitude. So 195HP turbo is comparable to up to 245 Hp at cruise RPM at 10,000 ft, given the loss of power at altitude for normally aspirated engines.

Wish I was your neighbour... would be annoying you every day. Great work. Do you use any vacuum bagging for the glass / carbon cloth work.. ??

@AusVelocity Год назад

My neighbors' are oldies and not really that interested but I'm always seeking advice or outside ideas or opinions. I can't think of anywhere that I could use vacuum bagging. Anything flat or curved has already been pre-molded at the factory and supplied. Almost everything gets a layer of peel ply to soak up excess resin and leave a nice texture.

@agriculturalsides9561 Год назад

Hello friend, I am a new follower in your channel about this amazing project. But I have here a discussion point . Maybe assembly from aluminum is light-weight and stronger and harder than fiberglass? What do you think 🤔 !

@AusVelocity Год назад

Well it's a pretty wild idea to build a velocity out of aluminium. Pound for pound fibreglass is stronger the steel so I'm not concerned with strength. The airfame has been tested to 6Gs and is designed to +10 and -7 Gs.

@Ebbrush3 Год назад

can you film you glassing the wings start to finish?

@AusVelocity Год назад

Yes, it's all filmed and I'm working that video now. Will have a lot of detail.

@AlexanderBingham Год назад

@@AusVelocity My wife and I are considering going down the same path you are on and we both appreciate the videos you are providing! Thank you sir.

@AusVelocity Год назад

@@AlexanderBingham No probs. We have no regrets so far. The build is the first half of the adventure.

@KuschallRacing 6 месяцев назад

it is so hard for me to trust sees thin-wall glasfiber wings to coap 200knots stress..it looks so fragil and like you build a gocart...and the twin motor version was hitting fare over 250 knots...how high is the stressfactor ?

@AusVelocity 6 месяцев назад

Well, it can seem shoddy from obsevation, but it's well tested, i think 200 IAS is the limit. I think the weakness is in the ailerons and rudders if they start to flutter. The strength with the G loading is way up there, tested at 6 but designed to 12, i think. Don't know about the twins. A guy in my local area will be building one with ul-power engines soon, I'll have to learn some more about it from him.

@jamesbarrick3403 Год назад

All of the plumbing and unnecessary weight to put the oil cooler in the nose of the plane. You can cut that air scoop anywhere. I'd look to have the air scoop on the bottom side near the rear and a simpler and lighter system

@AusVelocity Год назад

No oil cooler has saved some weight, work and money. I think I'll build a scoop at the bottom to hide the 2 inches of engine protrusion in the bottom cowl. The gearbox needs cooling so I might use the scoop for that.

@taw_prof959 Год назад

You don't seem to have gone down the Fast Build route, why not? If you were doing it again would you go for the Fast Build. I'm looking at doing an SE RG that's why I'm asking

@AusVelocity Год назад

Unfortunately, the fast build was out of my budget. If you have the budget, I'd suggest going as fast build as possible. Not that there is anything bad about the slow build, but factory hours are way less than amateur hours.

@public0105 Год назад

Let's discuss acoustics and vibration...

@AusVelocity Год назад

Awesome topic! I'm researching noise and vibration reduction at the moment. There are several measures I will and may implement that are not usually considered by aircraft builders. Usually deafening noise and vibration are accepted features in GA aircraft. We're doing something a little different. Give me a little while to collect some info and film some content.

@tinolino58 5 месяцев назад

Save weight and get rid of these silly headrests. Nobody will lean on them beceause they are to far back. Thats heavy automotive rear end crash „design“.

@AusVelocity 5 месяцев назад

Thanks, you're probably right. Without testing them out, I'm guessing the pros of cutting them off is less weight and better visibility for the backseat passengers. The cons are when passenger's lean back for resting/sleeping there is no head support. Given that the plane is intended for long trips, I think I'll leave them for now. Open to changing my mind before I upholster them.
