Azhar please do. I would like to know your results and thoughts on this as well.

Wayne if you're talking about me, no offense whatsoever. Always willing to learn more and hear other points of view. Plus if someone gets offended by "Hey here is my experience it works great for me" they must have some personal issues

BTW...When I talk about throttle response I'm not talking about the curve. So let's say your throttle stick on the TX is 3/4 way up but your carb is only half way open. That depends a lot on your setup: rod length, TX programming, etc... What I mean is that when the carb goes from 1/4 open to 3/4 (for example) the motor doesn't respond much in power and rpms. That's where the pipes, tuning, etc. come in.

Daniel you said that your 120 with pipes has great throttle response but you had to get used to it. What did you mean?

Wayne,

I might be interested in doing this for my 12X as well. Does Horizon do these routinely and for how much?

[Rainman]

Great discussion guys. Keep it goin we all will benefit from the pooled resources. Thanks Wayne for tuneing in, the more the better.

Ronnie, are you still considering the Ultimate? Have you done any research on it? Anyone out there flying the AW Ultimate (40%)? Please share your thoughts as to the overall performance of this plane.

Ronnie,
Not sure about the 12x, but typically, you don't need to send a radio in to get the ratchet function (if it doesn't have it already, i.e. heli radio). If you open the back case of the radio, on the throttle gimbal, there is a bar that lays over the curved surface on the back of the gimbal. There are typically two portions of this "slide", one smooth, for heli flying, one notched, for airplanes. It's simply a matter of removing the two screws on the metal bar and moving it over form the smooth surface to the notched surface. You can even play with the bend in the bar to get the desired amount of friction on the throttle stick to suite your taste. Again, not 100% sure on the 12x, but this is pretty standard configuration.
Hope this helps,
Kev

When I got my 12X it had a smooth slide.... I tightened up on the screw under the small rubber flap on the lower RIGHT section of the module when the transmitter is turned around with the back facing you. This made the slide stiffer, but it did not give me the ratchet action (clicks).

I do find it much easier to do snaps when the stick has a "ratchet spot" so that I do not advance or draw back on the throttle during snaps.

You do have to send in the transmitter to Horizon to change to a ratchet...it's not like what Kevin is describing with the FUTABA. If you purchase the ratchet, you may do more damage when you take off the back of the transmitter than it is worth. Horizon did not charge me to do the switch. You probably should give them a call prior to sending it in (if you do).

Yup... I know exactly what you mean..... & my engine does not "stumble" in the air before it picks up. This is why proper tuning and also a throttle curve is needed.

A person can fine tune the low end so much to try to get the "hesitation/burbling" out, with the end result that the engine is hard to start on the first time out for the day....especially when it is cold or the engine will shut down in the air when pushing in throttle in a "panic mode".... We all know what happens then!!
Hope you guys have a GREAT THANKSGIVING & safe flying when you all go out.

Wayne,

Thanks for the reply, I did set up a curve on my radio for my airplane and have 8 flights since doing that. All my deadsticks (6 out of 30 flights) occured before I set this curve up. I've got the dle 30 side carb in my airplane. Here is a picture of the curve I set up feel free to critique.

Carl - Have you tried (or thought about) the rear carb conversion for the DLE-30? Pretty much guaranteed to help with the deadsticks!!!! ...I know all too well what you're going through!

Hey Mike glad you'll be back flying soon.

Man, I'd still love to get the AW Ultimate. The only negative I've ever heard/read about the plane is somebody mentioning a need for flying wires for the wings under very high loads (walls and such) - don't know how accurate this is...

Unfortunately, I think my new plane fund will be used for my instrument rating early next year. Will have to fly the old tank for a little longer!

Thanks Wayne and Kevin!

I'll definitely consider this as I do miss the ratchet on my 10X. I agree 100% that it makes power modulation way easier and more accurate.

Thought about it but would need alot of modification for the plane to accept it. If I get another plane in the 30cc size, yes it will definitly be the rear carb version.

Carl

[JoeV]

cool DA 60 is out now... wonder if there will be any smaller ones to come out??? 30 size maybe?
