Bull-RCU,

If you have the Taurus, run it. The Brison works extremely well, but there's nothing like having more power!! You WILL have more power! There won't be any weight penalties at all. The reliability factor will be at least equal to the Brison. There would be no hesitation on my part to use the Taurus over the Brison.

"No" I don't have the Taurus, I have the Brison 3.2... Just after ready about the Taurus it made want one. I would probably sell the 3.2 Brison add some cash to get the Taurus. I'm not some extreme 3D guy, but I do want to be able to pull out of a Hover and do flat spins Rolling circles. I just don't want it to be underpowered. The reason I went with the Brison is I have the 2.4s and it has been a great motor. I just want to make sure it's not underpowered.

The Brison 3.2, which I have in mine, will leave you with no limitations either. If you don't have a burning need to spend the cash, then don't. With my Ultimate and the Brison 3.2 acceleration out of the hover is excellent. So is holding the hover. There is AMPLE power for ANY maneuver you want to do, including rolling harriers, waterfalls, elevators with change overs into other maneuvers.

Back to the Taurus. If you already had it, then I would say to install it. But if you have the Brison and the Taurus would be a new purchase I don't see the point. What many (if not most) fail to understand is that the differences between the DA50, the Brison 3.2, and the Taurus 52 are relatively minor. Most of those are in the engine weights, with the Taurus having a slight actual power advantage over both, IMO. Definatel not enough of a difference to run out and spend several hundreds of dollars extra for, or to sacrifice any value in a sale of the Brison to make the change. You'd be far better off managing the weight of the aircraft and making good prop selections.

I feel no need whatsoever for a larger or different engine from that which I already have in the Ultimate. That 3.2 Brison will not leave you wanting for more power.

Normally I would have used an MSC 22-8, but the weight of the Ultimate (light!) and the additional drag of the second wing pushed me more towards speed over thrust. The choice worked out really well. It's not fast unless you want it to be and pulls vertical out a hover, as some would say, "with authority".

For those that want to do the struts, here's some pics to work with. Shaft distance from the aileron trailing edge is 15mm. Harden or fill the inside of the aileron so not to crush. That's really important. The separation of the horn from the aileron surface is not important, as long as both sides are the same.

Status: online 		I'm just getting to the point of hooking up the ailerons on mine... that linkage seems like it might be a good idea... saves a bunch of weight and I already have 5945 servos which have plenty of juice... I just happen to have some extra MK clevices, control horns and some 1/8 cf rod around too... hmmm...

You are right... as long as the linkage connects at the same distance from each aileron the control throw should be identical. Might take a little longer to set up at the field but it's just an extra 4 screws to remove the connecing rod between the ailerons... hmmm... light is good, 2 less servos to power Are you getting any extra flex with this setup? How did you install hard points for the linkages int he trailing edge - did you just insert dowels?

So far I have my wings built, struts aligned, incidence set and tail feathers installed. Just waiting on my new Cowl so I can mount the DA50... probably another 10 hrs work and she'll be done. The build has been very smooth and uneventful so far... about the hardest part was making new aircraft-ply tabs - and that was darn easy LOL.

Chris.

Status: offline 		First, thanks to RTK for posting the pics for me. The server I'm using at the moment won't interface with RCU all that well, and pics just don't seem possible from this end.

Regarding the aileron stiffeners, I was in a hurry so all I did was to drill a hole just large enough to fit the tip if the Gorilla glue into. Squeezed in a bunch and taped it over until it dried. Seems to work so far, but installing an actual hard point would be a lot better.

Flex, what flex?? There ain't no stinking flex!! Really, there's no noticable flex, and control motion will be the same top and bottom if the angles of the horns equal the angle of the ailerons. Even if it ends up off a tad due to a miscalculation in the screw angles you will have far more than you need for maximum performance in anything. If you have more than 30 degrees of aileron travel with this plane you are going to get into trouble very quickly. Those that are used to setting up 3D aileron travels at 35 degrees and up need to re-think the issue for a biplane.

It does take a few minutes longer to set up at the field, but that just gives you more of a chance for a better pre-flight, and the time needed to answer all the questions from the other people at the field about how great it flys! I leave the struts connected to the bottom aileron during dissasembly, and use a small piece of velcro to secure the strut to the aileron control rod to keep them from flopping around during trqansport and storage. Then again, it will fit fully assembled in the back of a standard pick up.

Could you do me a favor? Would you post a couple of pictures of your radio and battery set-up if you get the chance? I'd like to see how you arranged your electronics so as to maximize access to the "innards"

Spoke with Tom at Wildhare today and he said he would probably ship my Ultimate this afternoon! What a nice gentlemen to work with. He was extremely helpful and made sure I was comfortable with the hardware selection I was making.

My Ultimate arrived a day ahead of schedule and the packaging was very effective - despite obvious rough handling in transit, the airframe was totally untouched. The hardware kit and servos arrived at the same time. Thanks again for such great service!!

I have a different way to mount the receiver, that I hadn't seen mentioned on this thread. Unfortunately, I'm on my way out the door to the airport, and will be gone all week. I'll post pics this weekend, hopefully on Saturday. You'll definitely enjoy your ultimate.
