I'm at the point of fixing the spider tube to the tank. The spider tube also carries the engine mount + engine and is bolted to the outer tube. On top is an oval hole for exiting the filler and vent tubes.

When using a TeeDee, the fuel feed tube exits through the hole in the engine mount and behind the engine. The Conquest, however needs to be mounted with the backplate against the motor mount ring. This means no space anymore for the fuel tube.

TD 09 Ducted Fan - Page 3 Instru15

The only thing I can come up with is to drill a hole in the side to get this tube out. I looked at pictures on the web but cannot find any similar case. If some of you have another idea...

I started assembling parts. First, I attached the spider tube to the tank with a smear of silicon and tape. The silicon tubes must have no kinks. The feed tube has a loop that sits in the hollow backplate of the engine. Next, the motor mount was fixed. As the engine has to be mounted against the motor mount base, the holes have to be made countersunk with a drill. Because the screws go deeper in the spider tube, I filed off the points to protect the silicon tubes. Then the clear centerbody was checked for a good fit and fixed with 3 small screws.

The .09 engine mount appears to be too weak for a .15 engine.
There is simply not enough meat on the beam to radial mount interface.

Brad, The engine mount is not for the 09. That one is narrower and fits into the stator tube. The motor mount I have is for the .11 - .15 engines. The whole kit was assembled like that. I don't have any specific 09 parts. By the way, the engine is also supported by the stator.

That's where I filed away the edge to make room for the crankcase.

I hope to bring this to a good end. The most difficult part is yet to come: the stator. That piece was already assembled by the previous owner. I have to reposition the 2 upper blades and cut off the tube. The whole unit is too big in diameter to fit into the outer tube. I'll have to take some material off the blades and still make sure that it's still centered!

The stator is modified. I widened the gap and repositioned the 2 upper blades. The major part of the tube was cut off.

TD 09 Ducted Fan - Page 3 Imgp6328


TD 09 Ducted Fan - Page 3 Imgp6329


Now this is not the end (as Churchill said).



When holding the stator on the engine, the gap between the back of the stator tube end the engine bearers should be 1/8". I have to make notches in the stator hole to slide it further back on the engine.

Today, I ground some notches in the stator tube as indicated in the instructions. This to go around the crankcase webs of the engine.

The first time I see this kit from Kress. It's a Morley ducted fan conversion kit for a TeeDee 09. Morley ducted fans seem to have an electric motor in the standard configuration.

I have a couple electric Morley units. I've never seen this kit for the .09. I seem to remember from the magazines Kress himself built an airplane using one of these, maybe that V1? I doubt I've ever seen anything else.

More DIY.

The stator will be bolted onto the engine mount but has remain centered at the same time. To do this by eye is rather difficult and not so precise. Therefore I made a little gizmo out of 3 pieces of plywood glued together. A first round piece fits the engine prop stud and 2 more C-shaped pieces are glued to that. The outer diameter is the inside diameter of the stator tube and can just slide into that. When done up against the prop washer, this piece sould determine the right position of the stator. At least, that's what I hope!

After some more grinding, a bit of swearing, fitting and more grinding, I got the stator ring to fit. I fixed the engine mount braces to the engine bearers. The instructions say to drill with a 52 thou drill (1,3 mm) but I found that too small. When mounting the #2 screws, you have to put too much pressure on the head with the shallow split that things wear out fast. Therefore, I redrilled with 1,5mm.

Today, I fitted the stator blades. On the left side, 1 blade needed a cut out to make room for the engine bearer.



TD 09 Ducted Fan - Page 3 Imgp6426

TD 09 Ducted Fan - Page 3 Imgp6427


I now have to fit this unit in the outer tube, but:

- the blades are too big
- the outer tube is not round
- the rotor has to be centered
- I have to find a way to insert the engine without taking it apart


The outer tube is made of Vivak which is a sort of PET like the plastic water bottles. This material seems to be stressed internally. When I cut the small tube that goes below the crankcase, the material folded back on itself. The outer tube has 2 holes, one for the cylinder head and one for the carb extension. These holes create unequal stresses, resulting in the tube not being round anymore.

Eric, I have to keep the outer tube because that fits exactly around the rotor. I'm thinking of making wooden forms to keep the tube round while fixing the stator. Once that is done, the tube will hopefully keep its shape.

Below a few pictures of the rotor mounted on the new RC Conquest with the custom nut made by Surferkris. The nut is perfectly made and fits as it should fit. Just great!! Thanks Kris!!

I'm glad to see that it worked out! Smile

There is nothing "standard" about that that nut, it is about twice as long as any of the commercial ones that I have seen, and the diameter is also slightly larger. They really should have included one in the kit... Wink

The standard Kress fan has the parts to fit a TeeDee 09. There was a conversion kit available for .11 and .15 engines. This kit had the countersunk fanss and also the nut and washer. In the box I got, This conversion kit was included but the nut got probably lost. I remember that the previous owner said on the phone he had a Webra or an Enya .11 for it and it might be that the nut is still on that engine right now!
