Status: offline 		No, I didn't do anything different other than what the manual said. When we first started our building of these planes, we didn't know about any wing joiner failures, so I didn't do anything other than sand the joiner (it was to tight of a fit) and used the G'Glue. Believe me, it has withstood some "tasks of flight" and I have not had a single problem.....so far.

Status: offline 		Thanks for this thread guys. After reading every word and book-marking much of the great advice whilst I looked for a kit, I eventually discovered a kit on sale for half price (which over here made it about the same price as over there), so jumped at it.

Mine has a Saito FG-36 for power as I'm not a 3-D flyer and am content with performing lower-power pattern-style aerobatics. One reason for purchasing this kit was to study how a big light bipe is constructed, because my scratch-built own design 71in span Jungmeister seen in my avatar, which is to the same scale with the same wing area and powered by another FG-36, is rather overweight at over 17lb. I've learned some good ideas from this kit!

I did make a pair of replacement wing joiners for the Ultimate from beech engine bearer, and also stiffened the engine mount by adding 1/8in birch ply plates fully covering the front and rear faces of the firewall, and a square of 3/32 liteply to seal the top of the engine box. I glassed the entire engine mount box, with glass tape round all the joints, and the whole then being encased in 6oz glass/epoxy. As guys have mentioned, the u/c is softly sprung, but as the Saito only turns an 18x8 there's plenty of ground clearance for the prop.

Pics 1 and 2 show my way of securing the top wing servo connectors to the rear cabane with white heatshrink tubing.

Pics 3 and 4 show the engine and cowl cut-out. I opened out the scoop beneath the spinner to force more cooling air into the cowl.

I fitted a 16oz tank in the location suggested by Maudib. Pic 5 shows the tank wrapped in foam plastic and secured to what was the Rx mounting plate with Velcro straps. The three 2S 2200mAh lipo batteries, one for the ignition and two for the avionics, go in the next bay behind the tank on a new plate, and the Spektrum AR9000 Rx is velcro'd beneath the cockpit.

The blue finned device seen above the battery is a Powerbox Gemini dual battery regulator, and the black rectangular item above the tank is a 4.8V 5A regulator for the ignition supply.

I've used all the kit hardware except for the hinges which I replaced with Dubro heavy-duty hinges, and I employed a Dubro E/Z Mount Cowl System instead of the wooden blocks.

Being rather wary of engine vibration levels, I've fitted titanium-geared servos all round, using Savox SC1256TG for the ailerons, and Spektrum AR6030s for rudder and elevators. These are overkill for the engine power I'm using, but I wanted to minimise the risk of crumbling gears. In fact the Saito doesn't exhibit much vibration at all, which is very pleasing.

The model came out at around 15lb as have several others on this thread, but the plane is a delight to fly, with its attractive colour scheme enhancing every manoeuvre.

The CG came out in the recommended spot, and could maybe do with moving back a tad. I fitted a Spektrum telemetry module and altimeter sensor, which shows that on a good day the ship will do more than a 600ft vertical climb. Though it certainly won't prop-hang on the power it's got, it isn't short of vertical performance for such things as consecutive vertical left-then-right rolls, or vertical snaps, with enough power and speed remaining after either manoeuvre for a short vertical line before a stall turn and then repeating the rolls on the down-line.

The climb-out from take-off isn't as steep as I'd like because of the lower power and it definitely won't pull up into a prop-hang from take-off! Landing behaviour is excellent though, with a slow nose-high approach and most times I can get it to touch down tailwheel first.

The model is definitely a keeper and I'm looking forward to flying it a lot.

Gordon

DLE 55 is very strong, pulls mine vertical out of sight at about the same speed as flying level wide open, good combination motor/plane for sure....

Status: offline 		I must say that is the best running engine I have ever had to set up. 1/16 turn richer on low and 1/8 turn richer on high and it transitioned perfectly spun the 22A at 7550 (peak was 7650 richened it till it went down 100 RPM) no burble at all.
I started on low rates thank God, plane was a little tail heavy. I originally checked the balance at 1" in front of rear cabane hole (wings off) but after a real squirrly flight I did the wings on check and at 6 3/8 (book ideal point) it was extremely tail heavy. All I can think of is the servos I used on the ailerons may be heavier than normal (Savox 0251 220 oz of torque). For now I am going to add 8oz on top of the engine posts. I checked the batteries and after over an hour of on time with ignition and a 10 minute flight it only used 302mah and I have 2 X 3200 life packs. I think I will order 2 X 2500 life packs which should lower my tail weight and allow me to remove the 8 oz on top of the engine stands. The plane AUW before the 8 oz came in at 14lbs 15 oz and now weighs 15 lbs 7 oz which is still not bad I guess.

That is a lot of servo torque for your ailerons! The airlerons are actually smaller than what is on a UCD 46. But your servo weight is about 2 oz so I do not think that is the problem. Mine weigh about the same.

I suspect your squirrly flight is not because it is tail heavy, especially since you have 8 oz in the nose and large batteries. I actually put my 5 cell NiMH (1700maH) pack in the fuse behind the wing to get it more tail heavy for 3D flying, plus I even added weight in the tail. I am running a DA-50r. I would check my trim, even have someone trim it up during flight. Also make sure your wings are tight and properly bolted. Double check this. I have my rates set very high - I even re-hinged my ailerons for more throw to limit the Torque roll during hover. I used all stock hardware. I presume you used the tail support wires and they are tight. Another thing, this plane can fly pretty slow without stalling, no need to race it around, though it can do that too.

This is one of the best flying planes I have ever owned.

Good Luck!

Status: offline 		The squirrly flight was before the 8 oz on the front . The next thing was it balanced perfect with the wings off method but after the touchy flight I checked it with the wings on method (per manual) and the tail would drop like a stone. I trimed it out on the touchy flight, if you trimmed it for level flight at half throttle then rolled inverted it would climb at a good clip.
