The OTHER Kevin in San Diego - 25 Oct 2005 21:59 GMT
Cleaned the garage this weekend and found a Midwest Model products
Axiflo RK-40 ducted fan unit (Similar to the Kress unit) and a NIB K&B
.46 Ducted Fan engine that I purchased back in the mid 90s..

Been involved in helis (RC and full scale) more than RC airplanes in
recent years and have the itch to finally build up a DF airplane.  All
my searching on line for DF model kits seems to point to the .91 sized
fan units.

Anyone know where to find a .46 sized DF model (I'd love an F-86 kit)
kit?

I know rcuniverse has more jet/DF flyers than this group, but I'm
exploring all info options.

Thx!

With the advent of turbines it is getting almost impossible to find DF
kits unless they are electric and they are much too small to adapt to a
.46. There may be some on ebay or as you mentioned, RC Universe.

A while back, someone was producing a .40 sized A-4 Skyhawk. Maybe someone
will help me remember the manufacturer's name.

I always wanted one of those after seeing one fly many years ago at the
Willow Grove Naval Air Station in a demo during a pattern contest.

I can't afford a turbine.  Actually, I can't afford to have the wife
give me grief like she did with my latest helo build up.  hehehe

A Skyhawk would be pretty cool as well...  I'm not completely opposed
to a scratch-build, but a kit would get me in the air much much
faster..

I've wanted an F-86 model since the 1st time I saw Terry Nitsch's F-86
DF model in RCM - probably in the early 90s...  F100, A4, A7 Corsair
II would all be pretty cool as well.  Maybe a Mig 15 or 21??  F104
would be sweet but dunno if my plank skills are up to the challenge...

Perhaps you could give her a cost breakdown on keeping a mistress.

I asked her "Would you rather have me go out drinking with my friends,
or hanging out here and fiddling with my models and passing on some
knowledge to [son's name]?"  End of grief.

As others have said, the glow DF market seems to have vanished at one end
there's the little foam electric DFs, at the other there's the turbines, but
nothing in the middle. I'm in a similar predicament with a Toki 18 and fan
unit - I'm hoping it's small enough to maybe fit into one of the larger
foamie EDF models.

I'm leaning toward an electric DF model myself. There - uh - I just
straightened up. That dang bum leg gets me every time. <G>

All kidding aside, Electric DF models are appealing to me.

Electric is looking better and better these days.  I actually picked
up an electric helicopter a couple months back.  I leave it in my
truck and haul it out at lunch to buzz around the complex here.  No
messy field kit or other support equipment.  Just plug in a battery
and fly...

I've been eyeballing an electric A-10 DF model at the local shop for a
while...  I'm gonna build the DF kit in any case..  Maybe strap it to
the back of one of my stick models..  hehehe

Just sent Larry an e-mail inquiring as to the feasability of stuffing
this RK-40 unit into his F-86 model.  Keeping my fingers crossed.

Thx!

No need to cross fingers, as Larry's Jet Hangar F-86 was designed to be
powered by a K&B .46 D/F engine!  He'd prefer you used his own Turbax
fan unit, but... The RK40 duct is built up instead of molded, and the
fan diameter is slightly greater than the Turbax, but it will work.  
Truth to tell, though, the plane is set up for the Trubax to be a
drop-in, AND it's a bit lighter and more efficient, so if he's still got
some old K&B .46 fan center bodies lying around, I'd opt for the Turbax.

I got his reply this afternoon.  He basically said the F-86 was a
great 1st jet but the Axiflo fan didn't work too well.  I'm going to
go ahead and build the DF unit in the next couple months.  I'll build
a stand for it as well and at least fire it off and see what kinda
thrust I can get out of it.  

I'd love to get a Wren 44 turbine for it, but I can't swing that kind
of money with risk of MIDS...  Modeling Induced Divorce Syndrome.  :)
