Yellow Aircraft F-16A to EDF?

I have an old Yellow Aircraft F-16A kit that I want to start working on again shortly. Not much has been done on this plane, pretty much still in kit phase. I had planned on using a Dynamax Fan with an OS 91 but since I see it looks like OS has discontinued them I probably should convert it over to an EDF.

What are your thoughts as to what should be run in this plane? Stick with a Dynamax or another fan unit (smaller diameter?). I do have several Dynamax fan units.

What setup would be good for it without breaking the bank? Suggestions?

Thank you for your input in advance.

First, if you want an OS-91, I have one!! LOL

You say " I have an old Yellow Aircraft F-16A kit " which leads me to believe it might be this one:
http://yellowaircraft.com/jets/f16.htm

It looks like the "newer " ones are this :
http://www.freewebs.com/yellowaircraft/mako.htm
A fair difference in length and weight.

You could of course convert it, Tam's has all the parts-- http://www.tamjets.com/original/prod...roducts_id=650
Just one for example.

All depends on what you want for perfomance out of the jet.

I would hazard to guess, that several of the high performance 90mm fans out there now, could also work.

They are the same length. The ones you posted are both yellow F16 C models newer version. So you posted the same plane lol just different websites.

The one he has in an A model. It is the same size but has a smaller inlet and is not made from epoxy glass so its the green stuff. Its also has less room inside then the C model. But its a little more scale if you put the time into it then the C model believe it or not.

I highly recommend a 90mm fan and keeping it light. Also a Tams inlet is needed.

Hoser just built one not long ago and it flies great I hope he sees this thread.

Jim:

I have owned and flown both the A and C models using the Dynamax/OS 91 and they both fly well, however, as Gunn has stated the A model inlets are smaller and more apt to "starve" the 127 mm fans unless additional intake area is provided. I would suggest, again as Gunn has said, that you consider using a good 90mm unit. I have been flying a Jetfan 90 V2 unit on 10S in my 15.5 lb. BVM Maverick and it does a good job of flying the plane. I am sure if you keep this plane light, the JF90 will provide very good performance.

Hey Jim, I'm doing the exact same conversion with my Yellow F-16A, I'm planning on running a Jetfan 90 but I;m not sure if I should use the stock intake duct and shrink the opening to fit the jetfan or just use Tam's. For batteries I plan on using a 10S setup, it should fly well from what I've been told.

Ok, with a jetfan 90, what motor would be recomended? Het, Scorpion, what model and kv rating?

As for the duct work should I use Tams intake or size the duct work I have? What about the exhaust duct work?

Thanks for everyones help so far, I greatly appreciate it.

seems to have a lot of YA F16 lovers over here

as i'am lock on my f 18 byron build for the moment , waiting for parts ( new esc's and fiberglass)
i decided to do a quick build ( well... trying to....) on one of my YA f 16 too
only with spare parts i have in the garage ,as esc fan ,servo's,ext....
this is a used kit , with cracks and dents here and there so don't wanna spend too much on this
decided to put a 90mm VASAfan with >HET motor 700-68-1200kv on 12 cells already have here
esc is a 120HV Hobby wing from another plane i've sold
no ducting planned , just a good lip ...

landing gear and retracts are from an order i did in the past and never used since today
some f 16 struts style and HK retracts are already fixed
some afterburner and led lights all around the plane is on its way
it will be a quick build as it is just to get busy while waiting for my f 18 parts
i won't do any paint job for the moment as the plan is to get it airborne soon and test it before making a serious build on the second YA F 16 i have in a box
if it flies well , i will take care about details and paint

wings are already glassed , servo's in place with functionnal ailerons and flaps..

stabs linkage are hidden in the fuselage ,with cool linkage found at JET power last week end
here's some pics
