RE: Boomerang TORUS build thread
nickelup,
I'm flying mine with a Kingtech 170F as I had it lying around. With 4 batteries in the nose, I still had to add 700 gms of lead for it to balance.
A123 - 2 x 2300mAh packs
A123 - 1 x 4600mAh pack
Flight power 4350 mAh lipo pack for electron landing gear.
Despite all these batteries being right up in the nose, I had to add 700gms of lead. If you dont much care for the dead weight, i'm sure you could install a p180.
Besides the weight, I am using the original Sullivan tank which has a capacity of 3.7lts. I only get a flight time of 6 to 7 mins tops with the throttle at 50-60% power and a full throttle only for take off. You might want to consider that aspect as well.
All the best.

Hi guys do you know if the airframe on a torus can handle a jetcat 180rx with 40 lb of thrust, or i have to throttle back for the jet not to break apart?

What you will find for sure is that with the split tank you will be out of fuel in less than 5 minutes with that power plant. I have a 170 in mine and the Sullivan tank and it's good for 7 minutes of enthusiastic flying and that's it. If I puts around I can get longer but if you really want the smoke I would consider adding a secondary smoke tank as I did with my build.
My Torus is going up for sale as I have purchased an Élan to downsize so I can fit the thing in my RV.

Here's my equipment list:
MAP retracts with mechanical ball link steering with Dreamworks pro-link struts and wheels
2x A123 2300's with Jr HD switches
JR 8411/8711 on main flight controls
Futaba 6014 receiver with Orbit power jack (can be removed and price adjusted down 200)
80oz smoke tank with pump,and speed control
Sport scheme with both wing tip versions
Currently has 2s4000 pack for turbine and 2s1800 pack for smoke in tray in nose - quick release for charging outside the plane
Is available with a completely rebuilt Merlin 160 just back from Dreamworks - zero timed
5000 for complete plane with turbine or 2600 without turbine plus shipping. I can ship from us address so no border issues.
I hAve it up for sale in Canada but may be the wrong time of the year as season is winding down here.
Here is a video of the Torus with smoke - very effective

The retracts fit into bays in the fuse center section and seem to be well supported and tied into the formers.
I used MAP retracts with Dreamworks Pro-link gear and Intairco Wheels/Brakes
The MAP retracts have the unique feature of a mechanical ball link nose steering eliminating the need for pull-pull steering wires with the associated hassles. There is also a ball detent in the pivot block so the nosewheel stays centered as it retracts. I tried and it will stay there even with the fuse 90 degrees on it's side.
I've done a bunch more work since these pics were taken and will try to add some more later.

The servos hatches are the standard Boomer issue. I had reservations about using these but some buddies with experience said they are pretty tough.
I added a piece of carbon rod over the rudder link rods as they are all threaded and pretty long. The rest are very close coupled. With the exception of the rudder pieces, the links are pre-cut.
All of it is Sullivan 4-40 stuff and great quality.

Why is it I'm having trouble seeing the pictures in this build thread? I just ordered a Torus today and was hoping to find any tips or pictures of builds. Also, has anyone done any cockpit work like adding a full cockpit or so on? What is a good sized pilot to use in the Torus? Thanks in advance.

Has anyone built a Torus since Larry has taken over Boomerang Jets and what do people think of the model of old and new? I just got mine Friday 12-30-16 and was just wondering if there is anything a guy needs to look for in the building process. Seems the last thread was from 2014 before someone current posted. Just wondering some comparisons from those who have built the original Torus and the new Torus. Also, what size pilot bust fits the plane without looking too small or too big. Thanks.

Good to know there is at least 1 other person working on a current Torus. I wish there was more activity on this thread. Maybe you should add some pictures of your build Edgar. Maybe that would get things cranked up again.

Plane is my favorite jet to fly. Nice aerobatics, no bad habits in the air, slows down very nicely, no tendency to tip stall. Big enough to see at a distance. Slows down nicely for landing. Prolink gear are great.
