45 years of modelling and about to do my first V-Tail Watched this to get a feel for it ............... BRILLIANT presentation and concise. I need to look no further, Thanks.
Phajh you may have just saved my first V-tail RC aircraft. I grew concerned that I may have had my rudder controls backwards, as I had set them up like they were Ailerons. So I did some research came across your video and yep I had them backward. Thanks for the basic but very well done video on how to set them up correctly.
60 years of modelling and never done an rc v tail but now I am working on one. My brain told me that to go left both ruddervators go left but my tx v tail set up had them gojng in opposite directions just as your video explains. I feel quite stupid but also pleased I have learnt something new. Thank you kind sir! Peter
Thanks. I wasn't sure how much influence the rolling moment was going to have which had me second guessing whether I was entirely backward and trying to induce a bank from dissimilar lift at the tail or operate like a conventional rudder. The wind tunnel was a bit out of reach so I thought I'd check UA-cam instead.
brilliant video could you please give me some advice i have built a model in the form of an eagle i have built in ailerons and also it has v tail it flies very poorly in fact horrible what do you think would be my best fix settle for vtail steering only and not use ailerons
after 1 flight with your recomendations already its a lot better to fly but the nature of the ailerons [foam] they seem to be very weak so i have stiffend them up now waiting for next test flight i will keep you posted many thanks john
Why would left rudder for v tail roll right? wouldn't it roll left like normal upright rudder? i understand it would want to roll the plane to the right given it is torquing the empennage clockwise, but the overall motion of the tail sweeping to the right would be greater, and would induce the whole plane to roll to the left.
PHAJH so you're saying that the roll force is only momentary/weak? yawing to the left usually rolls the plane left, I never see a slight roll to the right unless it is just covered by the fact the left wing reduces speed and right wing increases making a roll to the left. so if a normal rudder was inverted, say pointing more to the ground than above the tail boom, it would have the opposite roll (more in the direction of the yaw than away from it), right? but we don't have tails pointing to the ground because it makes it hard to land with unless you have really long landing gear like a uav, i'm guessing
Excellent! I really don't see any reason why it would not either. I plan to build a second Spectre out of insulation foam board from Home Depot, and this time instead of two routers and an elevator I think I'm just going to go with the V-tail.

You are most welcome!
Thanks that was just what the doctor ordered.
Great job
Phajh.... this was GREAT!. Thanks a million for sharing this with us rc flyers.
Very nice tutorial. Covers the topic perfectly! Thank you!
Thank you for the video! Very comprehensive.
Great Beechcraft Bonanza tutorial, lol. Thanks ! Very educational film. Well thought out.
Well done, thanks for posting the video.

Many thanks PHAJH, Great help for my Mini Talon.
Thanks that's a great help.
Great Vid. i was beginning to Doubt the v tail setup in a futaba manual . . .
Great video
Great think I got this. gonna test my Duralfly Excalibur soon
Thanks!
ty!
What plane is that??
what engine
Liked and suscribed
Thanks

many thanks for your help/ suggestion will try that

I mean, whats the difference of a conventional and a V-Tail planes. Theirs two RCs with both con. and V tail, so hard to decide...
I wouldn't think the V tail would be optimal for aerobatics. I was always under the impression it was purely for Speed and less drag
thank you

PHAJH and the predator drone en.wikipedia.org/wiki/General_Atomics_MQ-1_Predator
will a V-tail hold a knife edge?
Excellent! I really don't see any reason why it would not either. I plan to build a second Spectre out of insulation foam board from Home Depot, and this time instead of two routers and an elevator I think I'm just going to go with the V-tail.
