Status: offline 		i was just getting to like 3D because of this plane was just amazed at how well it walked around on its tail just floored me so maybe ill stick with the DA-50 sure flew well with this motor

My Ultimate made its maiden flight today. I had the throws per spec, and the CG set just a bit shy of 6.5 inches back. Flew hands off with 3 clicks of up. I only made a few laps just to get the feel of the plane, as the wind made it difficult to do too much diagnostic flying. The one thing I noticed was that the ailerons were very responsive. I dialed them way down when I landed. Plenty of power with a DA-50, and it floated in for a beautiful landing. Here's the specs:

DA-50
5945's on Aileron
8611s on Rudder, Elevator
635's on throttle & choke
2-1400 5-cell NiMH for Rx, 1-1400 4-cell for ignition
Weight, about 19 pounds

Status: offline 		Rather than let this thread fall way to the back, I'm going to attempt using slave struts on the upper ailerons, reducing the aileron servo count from 4 down to two. It will save a lot of wiring and the weight of two servos. I'll post some pics when I complete the strut design, mounting location, and figure out some of the geometry.

I'll also post some pics of some home made engine standoffs for a Brison 3.2. They are just as light as aluminum, perhaps lighter, and a whole bunch cheaper.

Ken,
Thanks for all your hard work in this thread.

Pat

Status: offline 		I believe that shouldn't be a problem at all. Since the ailerons are so so responsive, You can set up the geometry to favor lots of movement on the servo and very little on the control arm. This will basically double the torque of the servo even though you lose servo speed, but since this bird doesn't need extreme throws for a fast roll rate. 3D throws are not necessary for 3D performance.

Status: offline 		I did think of it, but linked ailerons can be a problem if not done right. If the pushrod flexes at all it can cause the ailerons to oscillate and possible flutter. It's OK for you guys to experiment but I have to sell something that works every time.

Status: offline 		I personally prefer separate servos, not only for a tighter feel but also for redundancy. Also a bipe has enough hardware already to hook up. I definitely would'nt want to add to it.

Status: offline 		Tom and I discussed this at length over the phone the other day and he brought up a point that I had failed to note.

The slave struts will work just fine but some things have to be kept in mind. Number 1, and this is the one Tom caught, is that there will be unequal travels between the top and bottom ailerons if you use a strut that surface mounts to the ailerons. The best way is to have the slave control rod exiting from the center of the aileron to a point inside the wing ala full scale. Experience to date has shown that a small difference in travels between the top and bottom aileron has an insignificant impact.

Number 2 is that the strut itself can't be prone to a lot of flex. Really screws up the performance of the upper aileron and doesn't do the servo much good. I've been doing bipes for many years and found a long time ago that carbon fiber rods seem to work the best for the weight involved.

Number 3 is the attach point of the carbon fiber rod to the ailerons and the pivot point. Done incorrectly and you can bind up a control rod and servo in a big hurry. Been through that before and found that the Nelson Hobbies pivot clevises will work fine in a vertical to vertical arrangement.

Number 4 is the lack of a econdary hard point in easch aileron for slave strut attachment. That one is pretty easy to get by using the existing hard points with the right connectors. basically just another 6-32 screw.

As I said before, I will complete the installation and full performance test flights, then post performance info. I will post pics and methods as they are performed.

Without being over confident, I'm certain that it will work out well. Tom is absolutely correct in providing this plane with a 4 aileron servo installation. Done incorrectly, slave struts would be a major stumbling point, to the dissapointment of the buyer. Tom has gone to great lengths on every product he has marketed in the attempt to assure a quality product that all can enjoy.

Status: offline 		How about this set up:
Evolution/MVVS 58 in the nose
4 5945's in the tail
4 5475's on ailerons?

Status: offline 		I am an advocate of lighter engines with this plane, but the Evo 58 is not that much heavier than a light 50. This should be an excellent combo.

Status: offline 		Yeah. I'd get a DA 50, but a guy I fly with wishes he had more power here at our elevation. Sometimes you gotta do what you gotta do. I just hope Karbonite servos are enough for the ailerons, but they sound like they would get the job done.
