Hello, I have a Sig fazer I've been flying all of last year. It has an LA .40 in it. It flies it well, but I would like more power and fly it better. Also I been looking at the higer thrust servos. Are they worth it? How much throw do you guys use on these types of planes. I'm building a morris the nife next. What should I use in that. And can someone explain mixing to me on a computer radio?
Thanks:
I'm only a PT40 flyer and a Fazer flyer.

If you want the fazer to go vertical try a Webra 50 in it or a YS45. I have the webra 50 in mine and it hovers really well and will accerate right out of it. The YS45 will also make it go vertical. I have that motor in my Morris Mustang.
High Thrust servos?????? You mean High Torq servos? If so, yeah they are worth it!. On my fun fly planes I usually have my throws maxed out and as high as they go especially on the rudder and ailerons, the elevator you have to play around with it to get it dialed it so it will loop good enough without it snapping out. Mixing really helps, but what kind of radio do you have. Some radios have more options then others. I only have and use futaba and hitech.
For your knife use the same setup as I mentioned in it. The morris planes are a little heavier then the fazer.
You could also try higher nitro gas. I'm just working on 40% nitro fuel. I have all my funfly planes that have webra's or YS's in them now using 40% nitro. That much differerce from %15 that i used to use sure makes a different. My funfly planes are quicker and lots hotter then they used to be! Soon time to give it a try with the new "3D menace!!!"

Hi PT,
I have a Morris Knife that I just got finished. I have the Saito 72 on it for power. I also bought some DS 3421 mini-digitals for it, but have not tried them out yet except on the bench. They are very small and light. The servos only weigh a mere 1.04 ounces. They are very powerful for their size, but are somewhat expensive. They put out 65 oz/in of torque at 4.8v and 81.25 oz/in at 6v. I'll be using a very light 6 volt battery. I haven't seen anybody try these yet so I really can't say how well this will work, but I feel certain these will be good servos. The geartrain is metal. I went with the lightest components I could find just to see how good I could get this thing to perform. As soon as I fly this plane some I'll let everyone know how the servos and things are doing. The servos look like a low profile 341 if you've ever seen one of those. They are very quiet and precise...and powerful...I about pinched the $#-^ out of myself playing with one! hehe It's really too early to offer anything positively about these, but I just thought I would tell you what I did on mine. Like I said, I'll definately let everyone know how they work out.

The best bang for the buck will come from a little more engine. Upgrading to a 46 or 50 and a suitable prop (i use APC 12.25 X 3.75's and 12x4) will make a world of difference. My favorites are Irvine 53, OS 46. Most others in that size range will do the job too.

In the servo department, it would be good to look at reducing weight first. Try HS 81 for throtle, and go with a smaller battery. I use 350 mAh, the 81 for throtle and standard servos for everything else. I typically fly over an hour in a day and have never come close to running out of battery. Less weight makes everything work better. For a cheap boost in servo performance try 6 volt. havent done it myself, but i hear a little more juice to those servos really make them come to life.


Anyway, experiment, tweek, discover, ask questions, and have a blast

I might be alone here but IMHO if you are looking for no hastle performance get a OS .46FX or an OS .50SX. OS motors draw fuel great in vertical. I would try a APC 12.25x3.75 or an 11.5x4 prop. If you do decide to get a new motor and go with a 2 stroke get rid of that stock muffler and put either a Tower muffler or a Mousse Can muffler on it or try putting a Mousse Can on your LA. You might do a search and check out the Mousse Can Mufflers. Something else that works well are OS #8 glow plugs. They burn hotter and do increase rpms. As far as servos I think that servos make a big difference especially if you are going to do knife edge or any maneuver that you need holding power. I would say standards are fine for the aelerons but you might want to upgrade for the rudder and elevator. I think that futaba S9001 are a pretty good reliable upgrade for about $45 a piece. Hitec 605's are ok except in my opinion Hitec analog servos don't center well at all but that's just my experience. As far as programming your computer radio I would just play with it. Start out with reading your manual and figuring out Flaperons and elevator to flaperon mixing for some really tight loops also great for low and slow stuff. I also use spoileron mixing for Harriers and elevators but be careful with using spoilerons because it makes the elevator really ineffective so if the motor dies with this on turn it off or look out. Yeah I've been their....Just my .02 cents. I hope this helps
