noblers & fuel tanks ????

[scott bolton]

   Hi Fellas, I have an arf nobler that i am installing a os46 onto. Does anyone have some accurate info on what metal tank will work on this animal. I had some problems with the original tank cracking at the corners. I believe the new 46 will be a little thirsty but with tons of POWER. Any help will be appreciated !!!  THANKS ahead of time Gentlemen & great flying. Scott

What I did on mine was to make a cutout in the firewall so my tank could slightly protrude from the tank area. I'm trying to remember the tank number (no luck!)---it was a "standard" Brodak Uniflow (4oz I think) with tubes facing forward.

Possibly I would suggest searching on Stuka Stunt Works--a few years back because there were quite a few posts on it at that time.

I cut out the firewall and used a 5 1/4  x 1 3/4 x1" tank in mine. It worked fine with a 35 FP for power. We are almost at sea level here so if your at a higher altitude you will be ok. OR you could use 5% fuel.

Why a .46 for power.  My ARF Nobler is still flying with Fox 35 Stunt and the tank that came with it.  It is lighter than any of the Noblers I have built over the years.  DOC Holliday

I agree with Doc 100%. Why so much power?    I have seen Noblers with powerplants from 26 up to 40 but the best I've EVER seen fly have been with Fox 35s. Mine is powered by stock Fox 35 an I could not be more pleased with it. I don't even use uniflow - just a 4 ounce tank (too much fuel-I remove some) with a standard single vent. The runs are perfect and the power is all I need. Mine weighs 44 ounces.

Is 5 1/4 oz enough? Check this:

I have an OS 35S modified to ABC in mine. If I do another, I'll use my Plasma Fox stunt.

Bob --

Correct lines and length is part of it, too, you suppose? What do you use? I assume .015 stranded, but length?

Also, do you know (back in the day when the Fox 35 THE engine) what lines were most common on Nobler, Ares, Oriental size stunters?

A Brodak 40 is a great choice for the Nobler, since it isn't much heavier than a Fox 35 (both without mufflers). If you use a tongue muffler, then you can pretty much avoid adding tail weight.

I beleive most used .015 cable approximately 60 feet in length.  If you go to a 46 you will have to use .018 I believe.  DOC Holliday

I think I may have stumbled onto something when I built my 57 Nobler.  I built it as per the kit even so far as the tank design and I put a Fox 35 in it with a 10x6 prop.   It flew great, except that I discovered it only lasted about 5.5 mins which wasnt enough time to fly the full F2B pattern.   After checking around I learned that the tank design was only 3 oz. 

So rather than re-designing the model to fit a larger tank, I simply soldered a 1 oz hopper on to the bottom of the tank on the inboard side and made a few holes (like a baffle) between the two compartments.

To my surprise, this worked exactly as I had intended it to and what's more, now if I ever get worried about an overrun, I simply pull up and fly high and it cuts out within one lap.  As such I have never had an under or overrun flying this model.
