Yes, it took about a week of evenings to put together. The pulley's are stock items but the main one is drilled out lighten it a bit. The main shaft is a 10mm carbon rod running in two ball races. This is a bit of overkill but it meant I could drill a 2mm hole right through the pulley and the rod to take a locating pin without weakening it. The prop driver (from the pulley to the prop) is an 8mm aluminium unit from Kruise (available on it's own I believe in 8 and 10mm sizes). This set up means the carbon shaft does not have to carry any torque - only bending moments. The bearings were initially mounted to the carbon/ply/carbon sheet "formers" using four bolts to locate the bearing. Then the bearing and bolts were wrapped with carbon tows. After the epoxy had set the bolts could be removed and the bearing pressed out of it's new "cavity". The distance between the two bearings/formers (40mm) was choosen to allow the rear former to be bolted directly to the firewall with the propdriver in the correct place. The hardest bit of the lot was drilling the 10mm hole in the pulley. I have a pillar drill but it's not very accurate and even the slightest error showed up at the tips of the 20" prop.

> What controller are you using? What are the spec's on the controller?

Well I have an old Kontronic 3P-0-35-14-32. This is a sensor based controller used for F5B a few years ago. It's rated for 12-45V and 35/70A. For sure they have a new model.

best regards

Colin

Colin,
Truly awesome!!! I hope you've contacted some of the printed magazines to see if you can get an article published at least about your gear box.

1/5th Scale Nieuport 11


I thought you might be interested in my latest scale project. It's a
Nieuport 11 built from the Proctor Enterprises kit.







The specs are:

Span 61"
Area 950sq"
Weight 10lb approx (24oz/sqft)
Motor Aveox 1817/2Y on 3:1 belt reduction (provisional)
Prop 20x10 (provisional)
Cells 24 x 2400mAH (or 3000 NMh)

This motor may not be the best choice it's just an old F5B motor that
I had to hand. It's good for more than 1400W but I plan to prop/gear
it for around 1000W flat out. Tests on 21 cells a 2.4:1 box and an
18" prop drew 800W.

The colour scheme represents N594 which served with No. 2 and later No. 6
squadrons of the RNAS in 1916. Note the French roundels on the wings and
RNAS roundels on the fuselage.

I've tried to make it as accurate as possible even down to the use of a
different font for the stencilled serial number markings on each side! With
hindsight the base yellow colour is a bit bright but with luck it will
dirty up ok.

The covering is polyester dress interfacing as recommended by a contributor
to rec.models.rc. Sorry I forgot your name but thanks for the tip, it
worked out great!

The eagle eyed will notice a few things missing...I have yet to add the
top hatch hold down lacing, wheel covers and a dummy engine. Anyone
know where to get a 1/5th scale Le Rhone? I know Williams bros. make a
1/4 scale and a 1/6th scale.

There are a few more pictures on my web site at:

and Proctor are at:

Regards

Colin

Beautiful job Colin. You obviously used the excellent Proctor plans for all their worth.
Are you planning to dirty it up with something like wood stains? (They work well with a little care)

You can make your own LeRhone fairly easily. There is an article on how I made a 1/5 scale version in EFI Feb 2000.(If you can't get a copy I can send a Xerox) Repetative but easy and strong without being too heavy.

Cheers,

Martin

Beautiful job Colin!!!

This is especially interesting to me as I am currently in the process of building the Proctor Sopwith 1 1/2 Strutter. As someone mentioned, the plans for these planes are great - beautifully detailed as are the kit parts. I am especially fortunate as I work with the draftsman that drew the Strutter plans (and others) and have a full set of AutoCAD plans to work with on my computer at home.

The Strutter is about the same size as your Nieuport 11. I plan to use a new AF40 with an Astro superbox and 16 x 8 prop.

I just started, so it will be awhile before I am to the stage that you are.

BTW - have you flown this plane yet? I hear from my draftsman friend that the gas version of this model is a bit trickey to fly. Good luck. Phil

Sorry it's not flown yet. I only finished the belt drive recently. In fact I ran it for the first time today. With the 3:1 reduction gear I got (flat out):

Prop: 18x10
RPM: 5200
Volts: 24
Amps: 40

This test was done using a very old battery pack that has been in store for a year. The volts and RPM fell off rapidly making the test somewhat inaccurate. I expect if I cycle it a bit it will come back to life.

This is a bit hotter than I would like. I have a 36 tooth pulley blank that I could make up, but it's probably worth trying to fly it first. It should unload a bit in the
air.

I still have some work to do on the plane: mainly making up the real flight battery and
details like safety wiring the turnbuckles.

Tricky to fly? Perhaps. I have a smaller DH60 moth that is 15 years old now and that is very hard to keep straight on takeoff. I'm expecting the Nieuport to be even harder so as a precaution I have added a giro on the rudder this time. If I have any concern it's that the ailerons will be a bit soft. Time will tell.

The Proctor Sopwith should also make a fine model, be sure to post photos.

regards,

Colin

I stand corrected. It was the Nieuport 17 that was reported as trickey to fly. Have not heard about the 11.

I believe that your 11 is one of their Museum quality kits. Mine is one of the VK line, not museum scale, but very nice.

Please keep in mind that the Proctor kit is a scale model of one particular Nie. 11; a reproduction, not an original.

Having built and flown many of the Proctor models, I can honestly say that the 11 is a wonderful model and flys just as well as it looks. I've had the VKs when they first came out and there is absolutely no comparison, either in the quality of the kit and the quality of flight.
