I maxed out the throws on high rates except for the ailerons. On rudder I eyeballed it to around 60degrees and on the elevator I eyeballed it to about 50, I'm thinking I can still do with a about 5 degrees on the elevator to help whip it around. My CG on the other hand is pretty much like it is in the book and it flies great, you really want to trim the model so she'll only require a breath of down elevator to hold inverted straight and level. I'm going to withold any more comments as I only have one flight on the plane now and that's the maiden the past Saturday but right now I can say I am impressed, this one's going to be one of my favourites no doubt!

Mine came out very heavy but I think I may have overpowered her ever so slight with the big Hacker I plonked on the nose. She weighs in at 585grams all up and all my hopes sunk into the ground when the scale spat this out as I read everywhere it won't 3D worth a darn when it goes much over 500g. Well I can confirm that aint true, sure I think the smaller E-flite motors will have a hard time dealing with the heavier weights and maybe that's what the comments reffered to but I can tell anyone the airframe doesn't mind the little extra weight, she tracks like an arrow (Yea really strange for a foamy, I love it!) and still gets down and dirty.

Big up to E-flite! My last E-flite purchases have been nothing but a pleasure.

Ok thanks, I have high rates per manual, elevator looks like about 40 degrees. Going to bump it to 45-50, and try some flaperon mixing.
Running a TP 1320 at factory 3D position, seems like it still wants to fall out of a harrier too easy. Or it could be my skills...

Yea this thing flys like its attached to an invisible roller coaster in the air.

Try the SFG's and T-wing. Everyone who has tried these mods has reported better high alpha flight tendencies. I know mine wouldn't hover or harrier very well until I added the mods. After adding them, whole other story. Much better harriers, hovers and elevators. Couldn't get it to elevator(well) without them. Believe me I don't like doing extra work to a plane unless it needs it and this one needed it to make it do what I expected it to do. Also try to keep the weight down under 18oz if you can help it. That makes a big difference too. I tried mine out with a 2100 pack and it would pattern fly fine but the 3D suffered with the added weight. My 2 cents.

You have a build link for those mods? I could probably copy the design off Blake's video but I assume the position and alignment of the T wing and SFG's is critical plus the weight. Any tips would be appreciated.

Ditto!

I have not tried the T-Wing, but the SFG's really help on 3D maneuvers, especially knife edge passes. Only problem I have is that my e-flite servo on elevator is no longer centering. This is the second one, so this time I will replace with an HS55 and hope it works better.
Only other mod, besides using some clear packing tape to strengthen the fuselage, has been to use "Great Stuff" foam which I spread at the weak point on the fuselage (upper part, above the exhaust opening). No more flexing in that area!

What is the best set up for 3d and also normal flying. The Manual said 3.5 inches of throw with aleron and rudder , where is this measured from. I don't think I can get three inches of travel on the rudder and aleron. I am using the DX-7 which switch do you set up for 3D? Is aleron/rudder mixing good? I am just looking for a good set up and also the wing fences where do you get them or how to build them?

With your radio, hold the the surface down like your elevator and put a ruler up to the inside most trailing edge of it. Holding the ruler stationary, move the control surface up and see if it lands at 3.5". Then increase or decrease the end-point setting in the radio till it hits 3.5". End Point is another way of saying "throw". If you want to get real accurate use a carpenters angle finder.

Allthough I'm not familiar with the DX7, I think you mis-understand the "3D switch", Find 3 switches, one for each surface. Aileron, Rudder , Elevator preferably 3-position ones and set different rates so you can limit the travel and sensitivity of the control surface. The 3D rate would be the switch position you set with the most throw. I would say 40 degrees or more.

I don't know if I can move my end point fare enough out to get to 3.5 inches. How long are your servo arms? I am using the longes that came with the servos. I am using the Eflite S-75 servos. To perform 3D manuevers the aircraft needs 3.5 inches of control movement? That seems like alot. Just asking, I know that is what the manual calls for. I may need to lenghten the servo arms to get the throw.

You need the 3.5"(or 45-50deg) if you want to fly decent 3D. The plane is light enough it needs all the throws you can give it. My D47's needed to have about1" to 1-1/8" arms(carbon scratch built) added to make it fly well. Not sure how big your S-75 arms are, but you can always make up some larger ones using phenolic fiberglass sheets or carbon plate. I would recommend the largest arms you can get for your servos. If they are too long(doubtful) then you can always drop back a hole or two. If you're just interested in pattern/sport flying tone the low setting down then just use dual rates if you have them and turn them up for 3D work. My 2 cents.

Is it posible to use the motor, esc, and servos from my typhoon 2 in an e-flite tribute??? or will the motor weigh to much or not fit?

You can get away with using the ESC,but I wouldn't recommend using the motor, and the servo's wont fit.

Anyway, after starting this thread MONTHS ago, I'm finally buying my TFX today! Gonna build it light using the E-flite 400, and 3s 1320.

I'm taking the gear out of my Lil Banchee, as I think this is a better overall plane. (from what I have seen/heard)

Using 3S 1320's is OK, but I don't know about an E-flite 400. Even an E-flite 450 may not be good. I'm using an E-flite 480 and it flies great, plenty of power, and just floats in for landings.

I use a 480 on my 28 oz. Seagull Extra 300, and it rips! A 480 on the TFX seems like overkill. I ALWAYS go for the lightest build possible, as 3D planes fly best light. I'll be pleased if it weighs in at 17 oz. AUW.

No build links just hack some depron and glue! Just kidding check out post #51 and #55 for mounting details. Someone has my templates so I can't copy and post them. Just eyeball it like I did. As long as you keep everything straight your surface shapes won't matter that much. Any "fences" on the wing will help stop the air from falling off the wing(and your plane falling out of hovers, harriers,etc.). I used my laser but the usual rulers, tape measures , T-squares and the like will help keep everything lined up. Good luck the mods worked great and everyone who has tried them has reported better high alpha flight.
