LLF - I stuck Hitec 2X 5645's on Ailerons and Elevators. The rudder is a 5945. My winter project is a Wendell Hostetler 27% Extra 300XL, and I'm planning on sticking 5945's all around on it. They're way faster than 5645's, but almost twice as much too. The 56's are fast enough though and have pleanty of power.

I'm going to have to try that teflon tape method. I've loctited again and used vice grips to tighten the muffler to the lock nut rather than the lock nut to the muffler. We'll see what happens. It's amazing how smooth this engine is, it purrs like a kitten at idle, but is a real screamer at full throttle. Vertical is incredible, and I'm only swinging a 18X8, soon to be a 20 or 21 X6.

Hey Shag

After owning 22 Saitos I can tell you without blinking and eye the muffler loosening up can be cured like this.

Get some Red RTV from the auto parts store this is the kind that can take heat. Put it on both the ext pipe and head threads and tighten them up all the way. She won't come loose and U can remove it when u need to. That Saito 220 is actually a much smoother motor then the 180.

Just an Update

My Dave Patrick Edge now has 5 flights on her with the Saito 220. My last flight was 7 min after landing I checked and I still had 1/2 a fuel tank worth of 30%. My tank is 16 ounces.

My DP Edge is built very light at 13.5 lbs and the Saito will get her in the air in under 11 feet. She floats in like a feather and flys all IMAC maneuvers with great authority. I am thrilled with this combination of power and Airframe performance.

Take Care and have a good Turkey day.

Shag- thanks for the info on the servos!

No problemo - I'm going to have to get a smaller tank and save some weight (like 6 oz).

Dave Patrick should be happy, he finally has a glow engine that will go well with his ARF's (Edge and Extra). What's really cool is that you can mount this engine inverted (unlike the Moki's which are a pain inverted).

Joe, what do you guys think about the hardware that comes with the DP planes? Is it worth using, or would I be better off replacing the control horns and such? I'm going to go with Hangar 9 Prolinks and Dubro HD ball ends for my linkages so far.

I have flown a DP 330 over this past summer, and had made alot of mods as were described on RCU ie. stiffened the ailerons, added hard points, and installed Rocket city hardware, H9 titanium links, Robart hinge points, except for the elevators, as not much clearence. Used B&B 1/4 scale CA hinges there. I have an OS BGX 3500 mounted on a customized firewall plate, pushed out on B&B aluminum spacers. I also moved the cowling out one inch to help on balance. This makes the cowling flush to the fuse instead of overlap, and I simply filled in the top part of the fuse to mate. Alot of mods, but Im telling you this is an awesome plane! The OS BGX I think is underated to the Moki 2.10. Both are similar in displacement, and the Moki may have a bit of an edge, but I have not compared. All I know is my BGX running with a cline regulator a 20x6-10 prop gets 6600 RPMs or a 20x8 prop gets 7400 RPMs. Its an awesome combination, and not one flame out or lean run. I have Hitec 945 coreless servos all around, which are metal gear hi tork and very fast. The BGX hand flips on one flip after the initial run (which requires maybe 2 or 3 flips for first run). You will love your DP extra or edge, its a fine aircraft!

I was wondering about the 945 servos and how they would work. I dont own a programmer, and dont fly with anyone who does, so if I went with the digitals, I'd have to buy one. havent decided yet, though. Looking at the torque specs and speeds on the hitec site, the 945s seem to be very close to several of the digital offerings.

I personally don't like those Sullivan control horns on the ailerons. I'd go with something that's not going to flex to the side. Those Sullivans are strong in one direction but very weak sideways. I was afraid of flutter on the ailerons with those horns. I'd use the Nelson HCL 70 or 71, they are very strong. Another good one would be the Dubro 913. I like your choice of Pro links and HD ball ends. Those are not for the Sullivan horns though. You need some good HD ones like the ones I listed above. I used the Sullivan on my elevators and rudder but I didn't use the ball link ends on the elevator. I used the Dubro HD safety clevises (self threading for 4-40 rods). The rudder is just 4-40 Sullivan golden clevises.

Another thing you should do is study the hard points and figure out the outline of them and if they go all the way through top to bottom. If not you may need to treat the soft side to CA like I did. Take a pencil and trace them on the surfaces. There are aluminum horns that Airwild sells that are similar mounting to the Sullivans but much better side strength. Those are worth looking at too. They are better if the hard point is only on the one side, but the hard point needs to be wide enough to capture the entire area of the horn's base so all the bolts go through the hard point. With the HD ball ends, I'd use aluminum servo arms like Airwild or SWB. I really like the SWB.

The pull pull cable and crimp fittings are fine. Very light and very strong stuff. I'd use them.

P.S. My elevator servos were in the tail for proper balance using Moki 2.10.

Joe--- I also have a DPM Edge ARC that I am starting to cover. I went for all the weight saving I could and did quite a bit of surgery to obtain what will be 12 lb +/- an ounce or two.
I have it set up for my YS 1.4 DZ. I have been looking over the reports on the Saito 2.2 and it sounds like a real powerhouse at about the same weight as the YS if you allow for the fact that the Saito comes with a muffler and the YS doesn't. My question is whether from your experience with the Saito and the Moki I will be in high performanceville or soso
city. The YS will swing a 18x10 APC at about 8500 rpm on 25% nitro.

Bob, mine is way heavier than yours will be, about 15 pounds with the Moki 2.10. It flies great does awesome 3D but lacks the vertical I'd prefer. Also pulling out of a hover in trouble will keep you on the sticks trying to keep from going in, especially low. That's at 15 pounds. Now at 12 pounds you will be in the ballistic power range and the Moki 2.10 would be a rocket. But the Moki 2.10 will weigh about 6-8 ounces more than the Saito 2.20 mostly due to the pitts muffler on the Moki. The Saito 2.20 would be awesome at 12 pounds.

My DP 330, had only hard points on the bottom of the surfaces. It did however have solid balsa top to bottom. What I did, was uncoverd surfaces, and added a small piece of light ply on the top of the surface, for a rock solid install of rocket city hardware. My H9 Cap was the same way, no hard points on the top of the surface, only the bottom. Needless to say, I did the same thing on it. Maybe its overkill, but I like solid installs. The Hitec 945s that are on my DP are not digitals, but they are coreless hi tork, metal gears. They are great servos. Fast and strong.

Anyone making a Pitts muffler for the 220 yet? I checked Slimline's site, they show an inverted muffler for everything Saito has up through the 180. Would it be the same muffler as the one for the 180, or is it different?

drbebob

That's wierd. My Edge ARC had hard points top and bottom on elevators.

shag555

I've heard tell that even the 150 will fit the 220. You better call though before you go and buy.

Miloh

Cool: I'll try it. I just figured the tef tape would vaporize with the heat.

My ailerons were not all the way through. I didn't check the elevators since I used the Sullivans which only need a hard point on the bottom.

Hi All,

I have two DP 330L's.

One I bought about 4 years ago and its the version one and the other I just picked up a few months ago is a version 2. Both have Moki 2.10's on them.

My 1st one weighs in just under 15lbs and I haven't weighed the 2nd one yet.

Great flying planes.

I need to weigh mine one of these days to see what it weighs as i have forgotton. I did not put it together with light parts like you can do now a days, ie spinner, wing tube, landing gear and batteries. It is what it is and will stay

Hi, gas engines are to heavy for this size plane. I have the edge with ys 160, at 12.75 Ibs. ballistic! paul.
