Alan Hahn got the first few flights on his Brodak 40 powered Nobler today. He may be the first in our area (W. of Chicago) to finish his ARF. It's got a few trim issues and the prop load needs more investigation, but it's getting there. The Brodak 40 has a lot of promise; very strong.

I don't think it is...he's wearing a beard.

Hey Alan, how was the CG? The booklet has me wondering with the photo of all the lead stuck to the tail. Do you think a hot .25 would be ok for power?

If I didn't know otherwise, I'd have said that was Doc Passen..

I'm using the Brodak's tongue muffler on the Brodak 40 and a 4 oz plastic tank. If anything I might be slightly tail heavy (but nothing I have noticed). So I needed no added lead!

On the 25, yes I think a "hot" 25 would work. I am not sure that my LA25 would qualify though. We have had some problem here getting good non-sagging runs on our LA (and FP) 25's over the length of a full pattern. I've been using APC 9-4's and 10-3's and launching at 11-12 krpm or so.

Well he looks similar to the pilot in the cockpit of the Nobler!

Alan asked: "Fred, would you like to fly the Nobler?". Well I couldn't refuse. The pilot however, was a bit concerned. Pictures of Alan's pilot before and after Fred's flight. Poor guy!

Well, now you are making me nervous (I thought the little guy resembled me). Did you notice how the pilot is sweating after the flight.

By the way, I bought the pilot from Carol Layton, who usually (or always) accompanies her husband Floyd to a lot of the midwest CL contests. She does a really nice job on the pilots, and the cost is very reasonable.

I also solved my Brodak 40 run problems. It turns out that the engine works best when it is the needle that turns, not the spraybar!

The Brodak 40 is really a great match for this plane. Right now it is using every drop of fuel in my 4 oz clunk tank. I am hoping that the economy might improve a little as I fly it more. If not I guess I am going to have to make my own tank, or have Fred make one of his really nice pinched tanks for me (hint, hint).

I made the plane basically stock, but I did cut out the leadout wire and replace it with some Sullivan leadout wire. However I did leave in the wire links. I will take a good look at them (need to pull out "Sadaam" for that). At the time, the links looked heavier than the stuff people use for hard line leadouts, so I thought that they should be ok. Their main downside is a propensity to jam up on the control horn. So I have been checking whether my leadouts at the wingtip look the same length. (I also gave it a pull test!)
I wonder if this might have been the original problem that Ben W. had. If the link was jammed, it could have popped out. It sounds (from other descriptions), that the link wire has been hardened, but not tempered, so it is brittle. When it popped out (maybe the first flight), perhaps it cracked. All and all, I would say to just get rid of the link. It is easy to pull the whole horn out anyway and do what you want to do.

I think the plane is a real winner.

Oh yeah! I remember seeing the rack of pilots on display at one of the SIG contests I went to. There's a large variety to choose from.

Fred probably just scared him with his bottoms...
I can't wait to get mine built and in the air. LA 40 will be powering mine and from what I'm hearing, I probably will change the leadouts too. They really are much smaller than anything I've ever used. I'll try to record how much time it takes me to change them. I'm guessing 1/2 hour would be about right.

Hey, Guys. Don't overlook the little Rustler Merco .40 for the Nobler. I used one in my late lamented flattened by Lincoln Nobler that flew so well at this year's VSC. It's an almost perfect combination. Plenty of power swinging a 10 X 4 in a pretty constant four stroke. Only weighs about eight oz with the two way muffler. With the rear exhaust option the muffler weight is behind the engine and thus impacts the CG much less than a side exhaust.

This little beauty only burns about 3.25 oz for a full pattern and that's 10 % nitro. It'll run fine on five percent (I simply standardize on 10% locally and 15% at high altitude or hot muggy conditions) and should burn under three oz of that.

This is a beautiful engine just begging to be used in these classic era airplanes.

Ted

p.s. Ian, if you read this update guys on the best source for this dandy engine.

Ted,

Do you know if the Rustler Merco 40 shares mounting dimensions with any other engines?

Fred

Fred,
I think you have it wrong:

Too many engines- too little time!

Fred,
Pardon me for interupting, but I am thinking of the Rusler/Merco 40 in rear exaust mode for my Stunt Machine project. I asked RSM about dimensions and was told it was designed as a drop in replace for the FP35/40's. The Stunt Machine is such a sleek ship, I think it would look really good with a clean nose profile.
Regards,

FRED,

AS I RECALL IT BOLTED INTO MY TUCKER'S .40FP HOLES PRETTY DIRECTLY. DON'T QUOTE ME ON THAT, BUT I KNOW I SELDOM DO A LOT OF MODS IN ORDER TO PUT IN A DIFFERENT ENGINE SO IT CAN'T BE A LOT DIFFERENT.

OK,
who is going to be the first to put an OS .40 VF with a pipe and a Bolly prop on one of these ARF's?

Will they bother to change the leadouts?

How far from the circle will it impact if they don't?
