Status: offline 		I am hoping to maiden mine on this Thursday. I ran in the new OS .46's really well to try and avoid the possible flame out or a dead stick landing. Hopefully my time spent and the three tanks of fuel I burnt through each engine will pay off! Good luck next weekend! I will let you know my results if the weather holds out!

I assumed you could not flair enough because of the way back CG. The elevator input is not much – low rates – I notice when I land I pull, right before the touchdown, the elevator full up. I try to image when you come in with one engine and already slow how much elevator you need to keep it from dropping to early.
Yesterday I made my first rolls and loops. Also I tried high rate flying, which I was very pleased with the results.
The dive test (35 degree and ¼ throttle) showed the plane try after 200 feet down to level out. This tells me the CG is just right for this sport flyer.
I ordered Retracts yesterday, this plane will look so slick and even performs better, I changed the wheels to 3 inches to clear the props – 12x6 for two OS .60 – and three wheels this size create drag and turbulences.
I hope you get your bird back up soon.

The picture is a “photo shop”, the upper is my dual ace the lover is the “modified” copy…

Happy landings

Status: offline 		Great Video G-Pete....I landed just a bit 'harder' than yours and suffered some 'retracts' Your tracked like mine - almost no trim needed and flew like'it as on rails' !

Hopefully I'll get my Dual-Ace this week..I too will install retracts..Have a set of old 'Rhom-Airs',with 3/16" wire....Put new 'O' rings in them and using Robarts Retract valve, and they work great...Planning on using 2- 46, Evolution engines.....Hey Blindsides, how is the weather over there?..Not too bad here....like to see the wind go down where it's OK to fly...thumbs are getting itchy......Good thread here.....will balance at 95mm.....

G-Pete,

Thanks!

Right at 85mm.
If the CG is to far back your Plane will pitch downwards, sounds weird – I know – but that’s the law of physics. This pitch moment you don’t want in low speed especially at landing. Your wings will drop from one side to the other, with any correction of the ailerons you loose more airspeed. At the landing you should steer with the rudder to hold course and way less or none aileron input.
At my video you see a little correction (cross wind) and then flair in with rudder and elevator. On the end of the run the plane hit a rock and the front wheel was kicked to the right. With my new 3 inch wheels this matter is solved.
I like how she flies and how predictable she is, with the 0.60 engines I make a pretty good speed and I like a precise airplane in high and in slow speed.
Here is a picture of the 90mm red line.

Happy landings
G-Pete

Mine are on order – should be in by Friday or Monday. What are you planning for the servo set up? Two servos, one for rudder and one for nose wheel or one servo with a pull/pull cable all the way back.
I think I put another servo in the front so I have a short pull/pull and I can take some weight off.
Yeah, retracts are the way to go!

Happy landings

Status: offline 		Hey guys, has anyone done the retract conversion yet, and if so can you share pictures...please...

I got mine a few weeks back and and just loving it...

I will install a gyro on the rudder and do in flight engine shut-downs...

Status: offline 		Hi;See you are using the gyro!Have never tried one hear they are supposed to help control on engine loss!Have looked at them in tower catalog is that what you are using would like to try it too.Sure makes a nice looking plane!

Status: offline 		Still, No reports of any one having main gear problems after a bunch of landings. 11 pounds is not too lite. I've had one or two maple blocks crack open on other planes that weighed less. Has any one else installed a rear brace on the mains [ like I did ] to stiffen them up ?..... is any one even concerned ?..... MM PS, Which is best way to balance, right-side up or upside down ?

P.S. I also used MACS pipes on my OS .46 SFs and from the side the exhausts look like turbo prop exhausts

Got my bird a couple of days ago and will make some changes...Will put one rudder servo up front (for nose wheel streering) and try to move the servos up, right behind the wing tube...also fuel tanks will be 10 ozs, instead of 8 ozs....going with 3" Robart wheels,with foam inserts, on the mains..haven't decide on size of nose gear yet...just going to take my time on building this one...Have two other twins that need to be test flown yet,one is a KMP B-25,and the other is a XF5F-1 Skyrocket ( Hobby Hangar's Kit)...My main puter is down...Had Mediacom broadband installed Wed. and ran good for 7 hrs. and then went bananas....they won't be here to fix it until next Monday afternoon..typing this note on my spare outer..was going to sell it,but good thing I didn't..think I'll keep it...nuff said
Anyway,back to the Daul Ace.....will try and install the retracts this week-end...............................Later

Status: offline 		I changed my fuel tanks too, The stock ones has 8oz, the Sullivan S728 10 oz they fit like a glove in there. It is a flex tank and work absolute in the mount. Without taking the mount apart you have no other choice.
happy landings
