There are five air lines going int the wing, 2 for the pylon releases, two for the gera, and one for the brakes. I ran them in the wheel well neatly in parallel and glued them down with RC-56. The result looks good - especially when painted with aluminum paint...

The last job on the wings was to get the pylons outfitted with the BVM releases, get them connected to the air lines, and paint the undersides of the pylons with aluminum paint to make them look better. Here's the result. You can also see the inside of the whelle wells after they were painted.

Now the wings are mostly finished (all that remains is mounting the wheel well covers and gear doors) and they can be used to test the air systems. That's next...

The final (I think) electronic items to be mounted in the fuse are the Nav. Light Controller and Autochute system from Details4Scale. Here they are...

The Weatronics RX has 2 antennas. One will be attached to a Hayes whip antenna that comes out of the dorsal hatch and can be folded down under the hatch for static display. This is stock according to the instructions. So the question is what to do with the second one? Because of the aluminum plating, I didn't think it was a good idea to have all of it inside the fuse or the wing, but how to get it outside? Ah ha, the pitot tube! I made the pitot tube out of brass tubing and made it part of the second antenna. At least some of the second antenna will be outside the plating. I'll probably disconnect the whip antenna and see how it does only in the pitot tube antenna during the final range checks...

Here is the fuse now with almost all of the items that are under the inlet ducting complete. The only thing left under there now is the steering cables for the nose gear and the installation of the nose gear strut itself. Here's some pictures of the inside of the fuse with the tanks in place...

I have to detail the nose gear strut and add the sensor for the AutoChute system before I can install the nose strut, so I'm off to do that next...

OK, before I can install the intake for (hopefully) the last time, I have to get the nose wheel setup. I had the scale parts from Dan Gill for it so I had to get those on there.

On the full scale aircraft, the nose wheel steering is just the lower part of the strut. Its hydraulic, but there is also a set of cables that go down to the steering box - backups for the hydraulics, I guess.

Of course on the real thing, the cables go up into the fuse (around another pulley no doubt). However, on the model, the cables, and the hydraulic lines, have to end at the top of the strut. The solution was to glue a plywood ring at the top of the strut to support the ends of the wires and the hydraulic lines (think aluminum tubing).

In addition, the nose wheel strut is where I mounted the wheel rotation sensor for Dan Gill's Autochute unit. You can see that glued to the bottom of the strut next to the right wheel and the wires running up the strut. There is a magnet that is glued into the right nose wheel that trips the sensor when it passes next to it. That triggers the final deployment of the chute by the autochute unit...

Here's the completed nose strut after a couple weeks of work...

Here is the nose strut mounted on the aircraft. I had to modify the nose wheel steering mount to move it further out of the way so that the steering wires don't catch on the scale parts.

Now its time to mount the tanks and the turbine hardware (fuel pumps, solenoids, etc. and then install the intake and the turbine...

What models of servos you used to ride his F-100?This servos is JR?

Bruno,

I have used all JR servo's in my F-100, they are DS8911HV's on all major control surfaces, DS378HV's on the slats, and DS390HV's for all the air valves in the system. This thread is 5 Years old so i don't know if Bob will remember what he put in this Hun. I'm sure they were what ever BVM lists in the instructions which back then when this was built it would have been the JR DS8611 or DS8611a for all the major controls and the i think 3121's for slats and i think 358's for all air valves.

Hi Greg and Bruno.

The manual that I have for the F100D lists all the flight surface servos as DS 8411s, and the slats as 3321s, which were analogue. This is the original list which of course is 10 years old now

As Greg has done, it would be prudent to fit stronger servos that are now available, especially for the elevators. Bear in mind that there is absolutly no room for any servo cases bigger than the 8411s on the aileron or elevator servo boxes of the BVM F100.

Can I put the flaps, ailerons and eleveitor servos JR8411 servo and what you put on shows for slats?

Bruno

Greg Wright

My Feedback: (6)

Hi Bruno,

If you are only going to run the system on 6volts these are the servos that you should be able to use with no problems at all. The DS8411'S will work for the Flaps ,Ailerons,Elevators,Rudder & Nose gear steering. The thin wing 378's will work for the slats, and the 368's for all the valves for the gear,doors,brakes and speed board.

roger,

I had no problems fitting the 8911HV's in to any of the servo openings. I just had to do a little adjusting to get them to fit. I did this to be able to run a straight High voltage system with out using any voltage regulators. My set-up is using the spectrum 12120 receiver with two 7.4 volt 2cell 4400 Mah batteries and no Regulator's. I also used the 378HV's and the 358HV's and it has been a super solid set-up.

bruno borges

Ok gerg I already understood. Thanks for the help.

roger.alli

Thanks Greg.

Those pics are exactly the servos I intend to use.. On 6V. I suppose I am staying with what I know works, 8411s have such a good reputation. I have not investigated the HV servos yet. No regulator is an attractive pro.

I have just last week installed 8411s in the wings for ailerons. There is no room to move here, but it all fits as per BVs plan..

Just an FYI, BVM *used* to recommend analog servos for surfaces that had hard stops, like flaps and slats, because they don't draw as much current when stalled, which can be important if the throws aren't adjusted correctly and the servos drive the surface against the hard stops.

For example, the original Kingcat manual called for 8411's on all surfaces except for the flaps, where it called for 2721's. The manual has since been updated to 8411's all around - but I have seen someone burn out an 8411 on a Kingcat flap while (too slowly) adjusting the Matchbox for the proper throws...

I installed all of the JR servos that the manual called for on the F-100F I built and as far as I know, they worked fine for the one, and unfortunately only, flight. I think any JR servo that has as much, or more, torque as the ones originally specified, and that can be made to fit, are fine.

I changed the turbine and the battery of my F-100F Super Sabreand forgot to mark the C.G. Now i'm not sure about thecorrect center of gravity. The C.G. is in the manual unspecified. It's only written that the C.G. is on the moldet dots just aft of the wing slats. To be sure, i want know how many is it in millimeter backward from the leading edge.

By the way: On my HUN the C.G was approximately 36cm (14.2") backward from the L.E
