If you want to put up thrust or down thrust in a profile fuselage plane so that it will torque roll better how do you do it. I am not talking about putting the thrust in when you are building the plane, I am talking about changing the thrust after the plane has been flown. This is to fine tune it so that you don't need a bunch of elevator in either direction so that the plane can torque roll better.

First....Pro file's dont like to tork roll. If you open the slot a little you can get some up and down thrust in there. Just twist your motor and tighten the bolts. Or slot the hole a little.

hope this help's

Tell that to my buddy Jess... He tork rolls his OMP Profile Edge all day long... right on the deck..... Of course he could do the same thing with a ugly stick too..... I think he tork rolls in his sleep.....

Hey PaulSwany,

Get your buddy Jess here on RCU to give us some tips about that

He's on RCU... His handle is V1VRV2... Do a search using his handle... and you'll see some pretty cool pics of him torque rolling...

The 1st day I saw Jess fly, is the day I started believing its "all in the pilot""

man i dont get it. I park my omp in a hover and it just sit's there. Ive tryed laying it on its back, strait up, dont know whats going on. I can cheat and use ailrons but ...... nahhh. Maybe i need a 4 stroke.

I think your gonna have to use the ailerons. Everyplane I have seen torgue roll, even 40% use their ailerons, I don't see why a small plane won't be any differant.

I am sure people will disagree, but everytime I see one, as a giant scale event, event pictures, and videos the ailerons are cocked to the left.

If it does not roll just a little bit in your hovers then you are not completely vertical. The plane might look perfectly vertical, but it usually is not. Everything has to be centered under the prop and usually that put's the airplane on it's back 3-5 degrees. If it still won't roll (which it will) let it fall back (down towards earth) a little and it will roll faster than you might expect. If you really want a quick roll let it fall back a couple feet and then punch the throttle back up and it will roll like crazy. You have to "pump" or as I say "punch" the throttle and it will keep on rolling. Makes it easier to hold a constant altitude in my opinion. If you're just a couple inches up, don't punch it!

Holding it perfectly vertical is the hardest part and is usually what takes the most practice (after you know which way to push the stick). To hover without needing ailerons to stop the roll you have to keep it away from perfect vertical. A little nose forward is what most people do. Don't take perfect vertical literally...

I have also found that my ailerons have no effect while torque rolling. I have tried to stop it before and without letting the nose down, it will not ever stop completely. The ailerons go right up to the fuselage and they are pretty big. That big wing just blocks it all...The Morris profiles are probably much better for that! I can't get the roll started with them either, but on my SE it really get's it going. It all depends on the plane I guess...

If you really want a quick torque roll get a .40 size plane with a tiny wing and a YS .63!

Now onto up thrust...

The screws that hold my engine on are a lot smaller than the holes that they go through on the engine...I can just take them out and move the engine around a tiny bit and screw them back in while holding the engine where I want it. I have done a lot of experimenting and have ended up with as much up thrust as I can get which is about 2 degrees. That makes it much easier to hover because you don't need that constant up elevator that it needed before...

A bigger heavier prop will also give you a quicker rotation when you "punch" the throttle, as long a it does not slow the engine down too much... Engine acceleration is much more important.

Hey BottleRocket,

That was great info!!! I'm printing that out for at the field use.


If you don't need ailerons to get the TR going, then you must need lots of aileron compensation to keep straight in a hover? Is this correct? Thanks

I'm not very good at hovering. I can only hold the plane about 10 seconds. But, I can say the Pen Knife will torque like right now. I agree think it has alot to do with being perfectly vertical. I've got a bushed .40 with an apc prop on this plane, and with a 36 inch wingspan might explain why this plane torque rolls so readily. Seems like once I get it in and straight it'll start rolling. It does it pretty fast too. I'm more concerned about it not rolling actually..hehe
It goes around the other way and I sooner or later dumb thumb the rudder. I need to experiment more and see if the ailerons will stop it from torque rolling.
Come to think of it, my Uproar torque rolls also. It has the same bushed .40 and prop as the Pen Knife. It doesn't roll as fast but it will definitely start once I manage to get it in that sweet spot.

" then you must need lots of aileron compensation to keep straight in a hover?"

Keeping the airplane nose down a little or back (for some reason that is sometimes called an inverted harrier) it will keep it from rolling too much. My ailerons don't make a difference on my profile, so I just keep the throttle steady and it won't roll... Just go out and experiment and you will learn a lot more!

I am far from being an expert on this...Where are you Wayne?
