Don't give up your day job.

In case anyone's nosecone got a bit worse for wear, here is a 3DP one.

Thanks Kallend for that I go ahead and get them fitted then

[kallend]

Sorry I am a dumb arse .That means nothing to me .I assume the smaller nozzle has more thrust ???

Correct. 130% is WAY WAY too big.

Someone has 3D printed off some smaller nozzle for my FMS Rafale .I see a lot if people are fitting these onto the 80mm Rafale .Not sure if I I want to mess with the original nozzles on my FMS Rafale .It fly OK to me with the original nozzle on it .Anyone fitted these 3 D nozzles on to there FMS Rafale and if so what difference does fitting smaller nozzles onto the Rafale achieve ???

The nozzles may be my design. https://www.thingiverse.com/thing:4827133 (there are others out there too).

The stock nozzles are 130% FSA

My nozzles are 100% FSA

if that means anything to you, you'll know why people are fitting the smaller nozzles.

(They look a lot better too).

What kind of battery combo do you use with this? I'm stock and I have to find the smallest 5000, 6s I can to fit in that tight battery compartment and be able to balance it. I think I had to carve out a little foam just to get the battery further back.

Hi, I'm using 2x 4S 4500 25C Roaringtop lipos, no foam carving needed, weight is compatible to a single 6S 5000 lipo. All important info about my upgrade, batteries, afterburner unit, nozzles and exhaust cans, ... you can find at the end of this earlier vid of mine.

Thanks Viper. Thats exactly what I was looking for.

So are Geeks nozzles printed at 90% of the size or 100% of the file size. Wondering about the OD of Geeks nozzles inserts at the widest point
Cheers
Bob

Don't you mean at the "narrowest" point? I believe you print them as per the file and not do any re-sizing of the file. If you look at my picture, you'll notice that where the nozzles attach at the front would be the widest point or the original opening. Now notice how the nozzles taper to become narrower than that, presumably making the final outlet 90% of stock widest point. You should not pay too much attention to those "outer" nozzles. Those are for looks and do not enter into the equation of what the actual exhaust outlet diameter is.

Thanks Viper. I bought Geeks and sent the stl to my friends for printing.
They look great
Thanks again
Bob

Viper I have a guy that just printed up some pilots for my RCAF Twin Otter. He could likely do the nozzles too.
which file should I send him? I dont know squat about 3d files. Should it be the feathers open or closed etc.
Cheers

We used this one: https://www.thercgeek.com/product/FM...rmance-Nozzles
I think the "open/closed" ones are courtesy of "kallend". Both of his are 100% FSA and I believe his replaces the whole stock nozzles. The ones from the Geek go inside the exhaust opening and are 90%, leaving the stock nozzles in place. They fit perfectly into the rear end of the Rafale. They simply just glue in - no fuss, no muss. I had mine done in bright red. One of my flying buddies got it and printed off a few sets. If you get it from the Geek, it's 8 bucks. I don't mind the looks of the stock outer nozzles.
