Volantex Ranger 1600 CoG testing 

Great review as usual! I'm expecting my 1600 next week and am really looking forward to it.

Great test! I have had a test in mind, and now I think I know what I'll do. A weight on the arm of a servo. Starting at 90 degrees I can swing forward or back or a linear servo with a weight. Good stuff as always Andrew.

This is gonna be my first arf. I been building and flying for 30 years. I thought I would give one a go. Keep up the great videos.

Thanks - an interesting test. As you say, it has a long tail moment. I took some measurements off a plan view photo and from that I got that the tail moment arm was about 3 x the mean wing chord and the tailplane area is about 16% of the wing area. Ignoring the downwash of the wing reducing the efficiency of the TP neutral stability would be for a CG at about 70%! (48% behind the 25% point). Even allowing the TP efficiency drops to 50% it suggests about 50% behind the LE should still be reasonably stable. Good to see theory fitting the experiment reasonably well.

Great video. Case proven. Will order one in the morning. No if's no buts. Been sitting on the fence for the last week.

Nice CG testing and great flying! Love the onboard camera and the close to ground loop was exciting ;-) Happy Flying!

Many thanks, Andrew

Hi Andrew. Just purchased a Ranger 1600. I noticed the fuselage has two spar holes, while the wing only has one spar. Is the same fuse used for both the 1600 and the 2000? Thanks. Love your videos.

Excellent video explaining CoG and its effects on flight. I think a good companion to this video would be one using a less forgiving plane. Thanks again!

Many thanks Andrew for your very useful information which has given me clarity and even more confidence in this great little plane. Much appreciated .👍👍 Darren

Yes, it's a great FPV ship for sure, I wish it wasn't so pricey though....lol...Your weather looks great, ours has dropped off some as we head into Autumn....Im relying on you Andrew for my Sunshine as our Winter shuts us down...:)

That is truly amazing. And a proof of good design (imo) . The latitude it should give you for fitting gear in different positions or exchanging say, cameras of different weights, gives a fair sized comfort zone,

I just found out the hard way that foam is magnetically attracted to trees. And the higher the branch, the stronger the attraction. I've had less then 10 successful flights with 3 tree adventures

Yes...how far back can you push it and what will happen? It is a good video and a safe approach to balancing CG, but it would be even nicer to really push it too far so we all can see what happens and learn from it. Sorry for the crash... We didn't see that in this video. Because you kept it safe now, we didn't really learn anything, except that the Volantex Ranger is really forgiving on the CG. Just some thoughts on a really nice video. Btw: so good to see how you guys get spring, whilst we get autumn coming up, haha. Keep up the good work!

cool video ... i am very impressed with the plane design ... Is that the PNP with stock electronics ? i ask because of the 4s battery ..... i would like to know if the stock ecs motor can take a 4s ???

Going to buy one thanks mate

Andrew, you did mention only once, at the very first aft cg shifting, of more down trim needed. Didn't you also more and more while aft and aft cgeing ? This would mean lesser and lesser profile resistance as a very useful byproduct !

Hi Andrew Great tests on a Fantastic model. You changed your motor from original build?? Did it fail or used elsewhere. What is the new one and is it as efficient and as much thrust as the 1100kV? Cheers

Can you advise about the FPV camera being used? Does it have WIFI transmitter or only SD recording capacity?

Maiden today ! My ranger 1600 go up when i decrease the troothle. My CG are on manufacturer point. Do you have one idea? Thanks you! ( France )

Really like watching your videos

I suspect the tail down attitude and climb under power might be down to decalage angle. Too much negative incidence on the H stab.

Hello Andrew I have a Ranger1600 coming anyway ,looking for a very good motor for it,,besides stock,I’m looking for one with some umph and yet still battery life,,thanks

in your other video link you said the CG was more back? with the 4s 3000

Andrew is there an advantage to having CG further back than recommended? More efficiency?

Hi Andrew nice flight. I have problem with my ranger 1600 . Wheh I throttle in flight my plane it leans right. When I glide without throttle go right. Do you have that problem and how fix it? Please help Thanks.

Mobius Cam is placed inside the plane or not?

You really don't like it, do you? lol..... Great Video..... order me one, I'm sold! Andrew, Fall weather is here for us, it's almost scary this year, we have horrible south winds and forest fires south of us, the smell of smoke in the air is acrid !!! My son's girlfriend has asthma and is using her inhaler every few minutes, horrible.

Hi, do you know if the 1600 amd the 2000 use the same fuselage?

Would you still recommend getting one, or is their another similar plane I should buy?

if your cg is too far forward for some reason my ranger its tail heavy

somehow i think you could mount the battery on the elevator, and still fly it. :-)

....the BG Eu shiping method is a joke. Unusable... But the V R 1600 is a best plane...
