Dave is a twit when it comes to launching, flying and landing EDF's. He should stick to pushers.....

I think torque roll Induced from the power of your body transferred to the arm, hand and into the plane. Like a curve ball in pitching!!!

Anybody got some of the 3s pack that come with the plane and not using them? PM me if you want to sell them. They work good on my T45.

In the different note, I just got the F86, there is no way that my plane will balance with the stock pack? I'm the only one with that problem?

Having an absolute blast with my F-18. I ripped out everything that was not foam and went for Don's Wicked 4800KV/Wemo Micro combination. Also put in HS-65MG servos. Seeing 440W on 4S 1300mAh and vertical is fantastic (590g installed thrust, 450g AUW).

Really happy that I could get this plane to balance using 2 x 2S packs. I hate adding dead weight to a model...

I'm using the wing-tip missiles only - would prefer none at all, but they do help with visibility.

edf torque roll $0.02

My results.
I have 2 phase 3 f-16s one is on 3cells with a good amount of power and one is on 4cells with yee ha, THAT is how and F-16 SHOULD fly amount of power.

On 3s you just throw it wings level with a slight pitch up angle. it stays level and accellerates

On 4s if I launch wings level with same up pitch I can barely get my hand on the stick to recover from the left hand roll. With that plane I have learned to throw it with wings banked like it is in a right hand turn, Then, byt the time I get my right hand on the stick, the plane is still doing the left hand roll, but it is just passing wings level, MUCH less pucker factor.

Note, these planes are trimmed and balanced so power on or power off they fly straight and level.

I've had my T-45 roll both ways on launch but I know why

- Right rolls *rare* - all were due to my fingers catching the trailing edge of the right wing on launch - fix was to move my hand back some more (behind the fan now)

- Left rolls - due to wrist twisting on release as well as finger vs thumb release movement and pressure. Basically I had already started to rotate my wrist as I was releasing the plane and was opening my fingers more than my thumb with the net result of the thumb pulling down on the left side of the plane as the fingers were moving up and releasing. This was made worse by fear of the roll and trying to get back on the sticks quickly!

You really need to try a few empty hand throws and concentrate on keeping fingers and thumb level - and launch with full throttle as that makes it *much* easier because the plane will fly rather than glide...

- Flat spin - caught my hand on the tail feathers... Not sure how but it happened lol.

I have dealt with torque roll on my AMX. Basically when the plane has too little airspeed and a high speed motor it will torque. But only at low stall speeds. All of the other jets I have had are fine. 9 times out of 10 you are catching your finger on something. These planes need a push to get airborne not a throw. If you do that and don't twist your wrist it will get going. Also do not launch at full throttle. Most people will tell you otherwise but really you don't need anything more than 3/4 to get airborne if you do it right. Save full throttle for climb out.

I take the stock 50mm T-33 and just pitch it underhand. It flies fine and gets on step quickly. Do not try to overhand it. Mine would just go into the weeds. Also, in case you were wondering the T-33 runs 51 mph with the basic setup and the 80 MaH pack that comes with it. Did the doppler today and I really need to order the Dons setup. I am so lazy!

Sounds like a lot of fun!! I run mine on 4s 20c 1000mah packs with a 4120kv 20mm inrunner in a wemotec fan. It is super light and fast! I will have to try that combo soon. Any idea what you are drawing? Mine is at 19amps and 298 watts.

EXACTLY!!! Don't know how many times I posted this explanation but newbies are not reading.

I rolled my first hand launch due to wrist action. After going back and analyzing my motion and seeing the cause, I fixed my throw to push. No more "torque" roll since. Don't ever throw like a Shortstop to 1st base!!!
