I build one 50 years ago! I made it with straight wings and made it U-control!

[@douglasslayback3441]

Classic…always enjoy the thoughts behind your trimming changes too 👍

[@user-gz2jp1kt9k]

My father built and flew one with a Holland hornet 049 back in the 60's.

[@joshuawfinn]

Hornets are fragile engines but absolutely amazing power. A Satellite with a Hornet must have been absolutely amazing.

[@user-gz2jp1kt9k]

As I recall he won the engine along with a trophy at a contest on the east coast. Might have been at Johnsville naval air station in PA. They used to give out nice merchandise.

[@lasersbee]

This is how I started (free flight) almost 60 years ago way before my first RC single channel radio.

[@joshuawfinn]

The best way to fly!

[@paulbizard3493]

So beautiful... And thank God for remote DTs... 😊 We have a Groucho Marx expression at 10:57

I'm a Rc guy, but i find this stuff interesting and pretty neat

[@steppenwolf53]

I’ve always loved free flight

[@user-gz2jp1kt9k]

Beautiful flight pattern

[@chrishard7616]

Great!! A good insight to free flight.

Charlie Brown's nemesis was the kite eating tree. Joshua has his airplane eating trees!

[@chadgriggs6895]

Great video. I love the lines of a Satellite

[@billkuhl442]

I built one from BMJR kit several years ago. Back then I really did not know what I was doing and crashed it so put electric motor and RC for throttle and DT. After comfortable with the electric put the TD .049 back on it. Many good flight but sometimes the engine would not run consistent. I remember Jim Hack Jr telling me I had did get it running strong every flight. Recently I have been working with some TD engines and I have learned a good deal. Looking forward to flying it again this spring.. The fuselage is rather heavy because it broke in the middle several times.

[@joshuawfinn]

The big key I've found is running Nelson heads, modern aluminum venturi housings, lots of nitro (35%), and a 5.7x3 or 5.5x2.5 APC prop. That seems to wind them up enough and get a flat enough mixture curve to make them run smooth.

[@billkuhl442]

Okay I do have Nelson head. I have found out most of the venturi I have been drilled out. There is another head, think somebody in UK starts with K

[@joshuawfinn]

@@billkuhl442 Kamtechnik are the folks making Nelson heads now. Drilled out venturis are fine if you're running a bladder. Of course if you can get a Kirn or Kustom Kraft needle valve, even better.

[@billkuhl442]

Yes, that is the name. I have some Kirn Kraft NVA's. One more thing I noticed you flying R-L, mine flies R-R.

[@robinbeckford]

Nice to watch power model trimming. Assuming the plane was built straight and true, what do you attribute the strong right turn under power to? Slipstream?

[@joshuawfinn]

Yes, plus gyroscopic precession. Satellites need a lot of left rudder to correct for it. Very hard to glide them to the right. California Satellite trim features right thrust as well. Yes, really.

[@TheKommercial]

I would be giving it some left thrust first to cure the immediate right hook before tweaking further. Just my op.

[@robinbeckford]

@@joshuawfinn It's always interested me that some power designs really haul right, while others climb almost straight though having similar pylon / fin / moment arm setups. (This is without warps or rudder offsets). I guess that there are other factors as well, and they don't always have the same degree of influence on the climb, and they are stronger as speed changes. That's what makes it so challenging. Here in the Uk, Satellites are rare, so thanks for letting me see what a 450 goes like (in that other video). K&B motor seems like a lot for a 450 wing, but it doesn't seem difficult to get it sorted.

[@tomdurkin7321]

Great video, now I know what I have to do to really enjoy Free Flight, thanks for the reeducation

[@daviddavids2884]

6:04 obviously, adding ballast at the tail should be done knowing that doing so Changes the model's dom and cg/c-m locations. ever try making one wingtip a tiny bit heavier. if done correctly, doing so has no affect on the model's longitudinal dom.

[@joshuawfinn]

Please by all means build a fast power model like this one and show us how to trim it.

[@magnusericsson8684]

Beautiful 😊

[@Colin399]

Very nice

[@jamestomaszewski4657]

I would like to see a closeup on your nitro motor starter,,I think it is very impressive…

[@alwaysflying6540]

It looks like he's got a peddle to activate it then pushes the aircraft into the cone. I also think it's impressive very user friendly

[@skaterboi8494]

I have a 320 satellite with a Galbreth mp jet .061. It's my favorite airplane to fly

[@joshuawfinn]

That must absolutely scream!

[@offtopicjes]

nice one josh, ive been interested in this sort of model but havent got around to it

[@joshuawfinn]

You've gotta get out to Tangent and have those guys show you how to get started with these!

[@offtopicjes]

are you going to the albany event in spring? ill be there hopefully flying competition.@@joshuawfinn

[@joshuawfinn]

@@offtopicjes unfortunately I can't get back out to Albany until December. Flying into Portland is expensive.

[@offtopicjes]

yea it is, well let me know when you plans to fly in oregon. i would love to meet up@@joshuawfinn

[@free_flight_field]

Nice flight ! lots of fun !

[@collinmccallum]

wow!

[@sunilvichar]

Great👍

[@Pesawatbambu]

Istimewaaa

[@f4udhorn]

Why wouldn't you be adding a little left thrust instead of less right rudder. And aren't Satallites suppose to glide right as well? Just asking.

[@joshuawfinn]

Left thrust is only good for the first second or two. In fact California Satellite Trim is 2 degrees *right*. No, not kidding. Stock Satellites are very difficult to trim for right-right. I don't really understand why, but that's how they go. Rear fin Satellites, however, can be trimmed in the usual way, right-right, and don't usually need any substantial left rudder either.

[@mitchmitchell515]

Lovely model man

[@davefoord1259]

Why is there a lifting section on the hori stab?

[@joshuawfinn]

It's a more efficient force balance layout.

[@davefoord1259]

@@joshuawfinn so is the cg way aft and the tail is lifting?

[@freesk8]

Now you're cooking with gas! :)

[@oliverbowen17]

What size cox have you got in that thing?

[@joshuawfinn]

It's a TD .049, completely stock.

[@user-ol8zz1zd3p]

I want to see the video of him getting it out of the very TOP of that tree....

[@joshuawfinn]

Yeah that was a complex enough retrieve that I didn't want to try to get it on video. Would have been fine if I'd left it til morning but my dumb self tried to do it at night and just got it stuck worse.
