I've been going back and forth between a Saito 180 and YS 140 sport.

The othe option is a Saito 220. I wanted to get opinions on how it'll do in the DP Ultimate. Too heavy? The Saito 220 weighs 6 ozs more than the 180 and YS 140. Do you think I will have to reinforce the firewall? I am also considering the YS 160, but it is backordered everywhere.

THANKS!

I have had the same question going around my head for a while, I think the saito 220 would have more power overall but as you say it would weigh in half a pound heavier than with the YS. I've heard although I have no persobal experience with the YS that the 160 is difficult to start and if you dont set it up just right and run 30% glow fuel in her she will not run reliably.

Iam just about to place an order for the saito and put it in the Dave Patrick Ultimate. It will sound great and pull it verticle at around 12.75lbs. Iam gonna fit it with the Perry pump so I can sit the tank on the C 0f G.

I will probably have to move the battery pack aft and locate servos in the tail to counter balance the weight but I feel this will be a minor inconvenience for all the extra power it will have. I just dont think the YS will be as strong of an engine as the saito since the saito is around .60cu bigger.

I would welcome any further comments and will post a flight report when ready.

Kind regards

That plane should be a rocket with the Saito 2.20. I've seen that same engine in a DP Extra, which is a larger plane, and it flew REALLY well, so you should be fine.

I also have a DP Extra 330L, I pulled the OS160 out because it wasnt enough for serious 3D aerobatics. What was the verticle like with this engine and did the engine run well.

I like the sound of the 4 stroke especially in a bi plane.

Hay all... I have the 220 in my 13.5 lb DP Edge and the power is unlimited!!! very awsome combo! I'm using a Zinger 20x6 with rounded tips and it hovers at 1/2 throttle or less and pulls out vertically with athourity. No need for $$$ 30% fuel with this engine. I use 15% Wildcat.
If you put this engine in a 12-13lb plane the power would be great!!!

Thank you thats really good information, people persieve that the DP Ultimate as a slightly smaller plane but it actually has 1230 sq inches of wing area so it really can take a motor this size. I was thinking of a 19 x 8 prop I didnt think it would swing a 20 x 8 fast enough. The AUW of the Ulty with this engine should be around 12.75lbs so by what you say it should rocket out of a hover.

What does the 220 sound like, I bet its awsome

I think I might be doing the same setup. The weight penalty is not that great and I can make up the weight difference in servo selection and RX battery. Something to be said about having stupid power. I have used the Saito 180 on the H9 27% for not so unlimited 3D. I can only imagine that I would get the DP Ultimate all together with the 180 and wish I had more. The engine weight difference alone is only is only a ounces more.

When you take into account that you have 1200 squares to work with you can sneak some things in. I am thinking mini servos for ailerons and throttle, and 5945s for elevator and rudder.

Its common sense that swinging a larger prop will make the plane fly better. I just wonder what else people are running besides the mez. 19x8. I imagine you could do a bolly 20x6 or something similar.

I think the main roadblock with the Saito 220 is the ability to fit into the Ultimate nose. You might fit it somehow if you mount it inverted. I will just stick out way too much if you mount side way.

Another thing, this DP Ultimate doesn't have that much ground clearance. So a 20" prop may be close.

I had it w/ YS 140 DZ, and it is as perfect a combo as I can get, except for the gas guzzling DZ, which goes through 24 oz in 10 minutes w/ throttle management. Frankly, I think the 140 Sport will be perfect w/ APC 18x6W or Bolly 19x6.

Yeah thats the only roadblock. I can either get another Saito 180 cheap (selling my new one in my H9 260) or try the YS 1.40. I was planning on mounting the Saito 180 inverted anyways. Even when I had the smaller DP ULtimate I mounted my engine inverted to help with the lateral balance. So I would do the same if I went with the 220. I just have heard that some people dont think the YS 1.40 is enough? I run my Saito on 30% heli fuel and it has much better performance on that. The specific blend is the Curtis Youngblood mix.

To me enough power is like hovering under half throttle and insane pull out. The cost of the engine dont bother me so if I am going to have one glow plane it will have the best of a glow engine ect.

I was thinking of the new DP ultimate for the DA 50. When I last spoke with Sandy she said it would be released soon. I want to stick to 35% and 40% for now - of course with the exception of the DP Ultimate and the foamies and the DA 50 will find a home on the basher plane.

I noticed in some other posts you had problems making the Ultimate tail heavy enough? I was planning on just mounting the RX battery back in the tail to solve that one. I am going to run a 2800mah lion.

That's with YS 140 DZ. It's more than enough power for me. I could get more thrust with a lower pitch prop, but I needed to keep the rpm down for the engine. So I think YS 140 Sport w/ APC 18x6W would get as much thrust as my setup w/ my DZ.

Seems like it will have similar power to the Saito 180. I have been running mine with an 18x8 PT model CF prop. Seems like a good choice. I have to fly mine much lower to the ground though! I do most of my flying low.

I have seen that video before a while back. The 80's music really takes me back...lol. Although I remember growing up in MI listen to the old school rap.

Ill have to consider that engine a good choice. The DZ version is the one I have seen for sale on RCU and is probably the one I would go for. On the other DP Ultimates I have had I mounted the battery as far back as possible to get them balanced for 3D. I think all of them come out nose heavy on purpose if you build them stock.

The EVO 26 also seems like a good choice. Someone else on here was happy with his setup:

32.8 oz
16x8-18x8
1,400-9,500

about right for that size of a plane.

I flew my DP Ulitimate first with a Saito 180, then with an OS 160...and the OS was a lot more fun. I loved that plane, will probably get another one eventually.

I've had a couple of the DP Ultimates, and flew them variously with Saito 150s, OS 160, and a Brison 2.4. I can tell you that the OS was by far the best, the Sato flew well, but not unlimited, and the Brison was a Pig. More power than you can imagine, it was like a slingshot out of the hover, but the weight made it fly horribly. glide was like the space shuttle. Total weight with the Brison was 12.5 pounds. Keep the DPM light, and it's awesome, let the weight get up there and it sucks.

I called Sandy up yesterday and ordered the ARC version of the Ultimate. And I just ordered the radio equip. for it this morning. I went with all Hitec gear, 225MG's on the ailerons, a 925MG for elevator, and a 945MG for rudder. A micro for throttle. I tried to optimize the radio gear for a tight budget. I haven't bought the engine setup yet, but was planning to go with the OS 160 and am very encouraged by what I'm reading here. =)

Other than engine choice, does anybody have any insight into putting this plane together? Things I should watch out for?

Not really, it's a pretty easy one to put together. I modded both of mine to have dual elevator servos in the back after flying with the stock pull pull on the elevator for a while. Flew much better, with greater travels and easier setup than the stock setup. Plus, it makes it easier to get the CG back. Sicneyours is the ARC, it'd be a lot easier to build a couple trays back there than it was for me to cut covering and recover.

The DP Ultimate is easy to put together and the quality is top notch. I had a ton of issues with Saito 180 dead sticking on me in high g stunts. Since then I bought a fuel regulator and all is fine. ncrego is right about the elevator... the pull-pull doesn't give the deflection I wanted for 3D, but you can still get by. I'm going gas and just finished the Great Planes Ultimate with a DA-50 in the nose. Here is a video of my [link=http://www.youtube.com/watch?v=8krPaYdN-D8]DP Ultimate[/link] flat spinning... and then deadsticking...

Brown dropped my plane off today and it's beautiful. Or at least it will be in a few weeks once I have it ready to fly. =)

Can someone help me out with the Cabane attachment inside the fuse?

I'm finding that the ARC version needs a little more reading between the lines than the ARF. Some of the hardware attachments that come complete with the ARF are left for the builder with the ARC.

Attached is an image of the hardware I received in the bag with my cabane. Can someone verify that the correct way to attach the cabane to the fuse is to go SHCS, washer, ply, cabane, washer, nut?

And I'm guessing that the rubber grommets and servo-style screws are for attaching the canopy?

Thanks for any help.

Yep, you want to go with the SHCS, washer, ply, cabane, washer, and then then nut. The rubber grommets are for the canopy, but my ARF came with the socket screws (black ones in your pictures) for the canopy.

Thanks for the help!
