Sloping fun, show your pictures and videos !!!!!

Keith, with regards to V & T tail models being faster it's to do with parasitic and "junction" drag. Basically a T and a V have fewer junctions with the fuz than a + tail draw a V, T & + and you'll see what I mean.
There are trade offs however. Booms need to be stronger for a T and they frequently crack just ahead of the fin in anything but a perfect landing. V tails can be hard to set up as there's always a bit of coupling between rudder and elevator.
If you look at the F3f/b scene, there's a move back to + tails
Happy Days:
Thanks Bill,
When you say ‘parasitic’ drag I assume you mean ‘Form’ drag. :?: I’ve always understood that parasitic drag was created by items that project into the airflow that are not directly used for flight. (Undercarriage, antennas, pitot tubes, ect.)
Thanks for the information.
So the big boys are moving back to cross tails are they? Well, “There’s nothing new under the sun!”

Hi Keith , yes the phase 6 is the professional plane.
It flys a world apart from Johns 6.
I am now back at 130mm CG and it now shows a little more neutral in inverted flight , dive test is about as good as I can get it.
Rolls are slow and lift is so bad.
If you want to just go up and down the lift then it is ok but for me it is totally crap.

Happy Days:
Hey Richard,
Shame your’s is the full symmetric wing. :( I’ve never heard a good word spoken about them.
Just for your info, Chris Foss sells separate wings for the Phase 6, so you could buy a semi symmetric wing and fit it to your fus. You’d have much more fun with the plane then. :)
I don’t know how much the wings are, the entire model is only about £80.
As a further point, if you did get another wing you could build it into a full house wing. :D Separate flaps for crow braking and light conditions, combined flaps/aileron mixing for aerobatic fun in stronger conditions. :twisted:
Just a thought, ol’ fruit.

Hi Icewind, the Fox is by windrider, made from bouncy EPP and it flys fantastic.
I used tape to strenghten the winds and only glue used was to attach the elevator ! Total weight with battery is 437g !
I used a standard servo for the elevator , Hitec 55 for rudder and EMAX ES08MA metal geared servos for the ailerons. The emax es08 are the best small budget servo I have ever used. and check the price http://www.expressfly.org.uk/shop/product_info.php?products_id=281
This is my baby Fox fly on a windy day, the more you cuddle her the better she flys !!!!!!!!!!!!!!! just for Keith

Much appreciated the info provided.
Indeed it seems a great flyer, I found two version e-powered or pure glider. But I'd go for the pure glider version.
Been EPP and wing detachable (right??) makes it perfect for me.
It's about time I put aside the ones I try to build from scratch and never fly. ( Not sure why 8) )
So I can move to the balsa glider like the big boys in the slope. :)
Also thanks for the tip on the servos, for a metal gear servo that price seem very good. I was using Hextronik MG-14 on the same specs and price range but very often you find some that jitters...
