	As the Christmas building season approaches (and I can justify 
spending more money on models), I am considering building an intermediate/
advanced slope glider.  I am looking for something to build around two 
S-133 servos, a FP-R114H 4 channel receiver, and the NR-4G 250mAh battery
pack.  

	This past summer I saw a couple guys flying these small, scale P-51
slopers out on the Palos Verdes Peninsula just south of LA.  They were 
very fast, and seemed to be quite maneuverable...not to mention that 
they were guided by excellent pilots.  From a limited look around at the
kits available, the only scale P-51 I found was the Dago Red glider.  

	Has anyone had any experience with this model?  Are there any
other models of this type around, either in a kit or in plans?  Also, 
what are some good sources for slope gliders in general?

/* ---------- "extensions from engine to propeller" ---------- */
I would like peoples opinions and experiences on using a shaft
to move the propeller farther in front of the engine (instead of
'directly' in front of it).  I curious about problems this leads to
also.
Thanks

**************************************
    
     Fox has been selling a shaft extender set for many years. Extending
  the prop farther out is handy for longer, more pointy front ends on
  scale models, etc. Some of the racing people do it to get a more stream-
  lined front end too. It works really well on scale jet models that aren't
  using ducted fan engines for power, but instead use a regular reciprocating
  engine up front. In some cases modelers used extensions to move a pusher
  engine farther forward to better balance the model.
     Long extensions are trickier as you have to be really careful and keep
 everything straight with no wobble and really balanced well too.

     Except for keeping eveything a straight as possible without any wobbles
 and ensuring everything is well balanced it doesn't pose any big problems.
 The model boat people have been doing these things for years in pusher
 configurations, a tractor prop extension would be easier as you don't
 have to deal with a back thrust problem from the prop.

Not quite: my Futaba 7-channel PCM Rx fit in quite nicely. It needs
a radio with elevon mixing to take advantage of the wingeron capability.

I agree, it's a nice slope ship. However, I've flown other slope machines
with equal or better performance; the Coyote comes to mind, or the Salto,
especially when built light; there are several others as well. Concerning
wing flutter: I've had mine at max speed in a dive, with no signs of
flutter. I suspect this is due to the servos used. Use the strongest
metal-geared servos you can find; anything else may give way. Expensive,
at $50 a servo, but worth it.

Hi All,

	I was going to install a Robart ultra fueler to allow me
to fill my tank easily.  I chose this fueler because it automatically
cuts off the back pressure from the engine to the tank.  The YS61 taps
the crankcase pressure and as a result the back pressure to the tank is
substantially greater than if the tap is taken from the muffler (as is 
usually the case).

My question is has anyone used the ultra fueler with the YS61 LS?  I'm
starting to wonder in the ultra fueler itself can withstand the extra
pressure.. I would hate to install it and has to remove it a couple 
months later from a fuel soaked fuse.

Also, what type of refueler do YS 2 stroke users generally employ?

Thanks
Paul

I haven't seen any problems in using shaft extensions. You will 
need to bore out a larger hole in the prop for the prop nut to
tight down on the prop. The only manufacturer I'm aware of that
carries prop extensions is Fox Mfg. They have it in 1/2 inch and
3/4 inch lengths for 1/4-28 or 5/16-24 threads. 

Putting a shaft extension on engine may improve the appearance
of an airplane if it has a long skinny cowl. It may help in
shifting the CG aft by moving the engine back from the spinner
ring. It also gives more clearance between the needle valve
and the prop disk. I'm not aware of any problems using an
extension besides having to bore a larger hole in the prop 
and having extra hardware on the airplane to contend with.

This may be above your budget, but... well, let me give you a little background first... :)

I first got interested in RC Helis about 5 years ago, but I didn't get one.  Those that are familiar with the EX-employee/manager/owner/whatever.he.wished.he.was guy named "Reggie" at Capstone Hobbies will understand why. 

But in addition to the total lack of support from the ONLY store (and source) of heli-help I could find with at least an hour's drive of here, was the problem with the costs... not so much in the initial purchase of all equipment (I was and still am a newbie ;), but the cost to maintain it...

The hot choppers at the time were all in the .60 class, and made of metal, etc.  So you crash one, it is gonna cost ya!

I recently became interested again (usual 9 month cycle for 5 years now), and this time got in touch with the officers of the local club.  Helicopters are better, cost half as much to buy and maintain, and there are more people into it.  I was so afraid befor ethat I'd spend over $1,300 for a real good set up (remember, the only hobby stuff I own are X-acto knives, a dremel, and a tube of zap-a-gap), but then not be able to afford to spend all the money maintaining it.

The prices I had to go by were the local shops, and they are still high!!!! Still high considering they still have some helicopters that looked mighty familiar, then I saw the "New Model for 1990!" sticker on the box, and the price hadn't dropped!!!! $419.00!

Well, talking to the people at the club, I was told I could get a great (read: GREAT!) beginner helicopter, like a Kalt Enforcer or Concept 30 for around $250.  This isn't much more than the Sport 500 you were looking at, and it has all the modern heli technology.  The Enforcer appears to be the local club's favorite, and they know all the little upgrades and ins-and-outs of it.  They also mentioned the Kalt Enforer ZR coming out which is basically an Enforcer with some upgrades.

I think it does need a 5 channel radio and it is a .30 sized heli (which are about $119).  I don't know much about the Sport 500, but a problem with helis is cooling the engine, so using a typical airplane engine may cause some problems (since an airplane engine is exposed and a heli engine is basically inside a tupperware box).

So check it out thouroughly first... by spending an extra $100 or whatever, you might get a lot better heli/engine and be greatly satisfied instead of disappointed.

JT

btw, anyone have any info at all on the Enforcer ZR??  Also, I didn't mean to imply it was just a beginner's helicopter... from what I was told, "it is all in the set-up!"  ;)

Well we are due for a new thread, so perhaps this will start one ;-)......


While flying my newly repaired Jensen Stick (Foam wing etc but that is another
story!) I had two episodes of the following. The first flight of the day was
quite nice. The plane has an older ST60 on it. I have been flying 5% Omega for
quite some time and Fox R/C Long plugs. First flight is in the 12 - 15 minute
range. After being down for awhile (meaning the engine was cool) I went up
again. 7 minutes into the flight and flame out. Bring her in and check the
engine. Not overly hot, doesn't seem too lean. Back to the pits. Check the
plumbing visually and everything seems ok. Try a third flight. Again a flame
out and back to the pits. Now with some help I reset the low end and top end
needle settings. They were off some. The plane had sat for awhile during it's
hospital stay so I guess with the weather being different it needed some
tweaking. So with the low end set to give a good transistion and the top end
leaving a nice vapor trail away I go again. Flame out at the 7 - 8 minute mark.
Got her in (this dead stick stuff is getting a little hard on the nerves by
now). So I pack it in and head home to replumb the tank, and clean the carb.

Next session 1st flight is fine. Second flight 7 minutes and flame out.
Multiple nasty words later I'm down and trying to figure out whats going on. A
suggestion was made to try a hotter/cooler plug. My replay is all I have are
R/C Longs. The suggestion is made to try a K&B with no idler bar. In it goes,
retweak low end and top end needle settings and now it flys like a champ! What
gives? Flew fine for over a year on R/C longs. Always on 5 or 10% fuel.
Typically Omega. Engine is probably 7 - 10 years old. I am the 4th or 5th
owner. Can anyone explain why things got better. The statement was also made
that this fellow NEVER uses plugs with idler bars in anything of a 60 size or
larger. But he left me no explanation as to why.

Thanks!

I know a little about the onithopter efforts taking place at the
University of Toronto.  Jim DeLaurier and Jerry Harris spent 20 years
on the design of the world's first RC powered ornithopter.  Up until
a year ago there only claim to fame was that they had a ornithpter
that flew but did not sustain flight, i.e. climb.  (MaCready's pterodactyl
did this too.)  I was contacted by Jim DeLaurier to design them a new
airfoil specifically for the task of flapping.  With the new airfoil, this
improved matters just enough so that it could climb.  Coverage of the

Scale helicopters are typically fiberglass (once in awhile, wood) shells
wrapped around normal heli mechanics, so you probably won't find 'plans'
as such.

Helicopter World of Milpitas sells an Apache fuselage of sorts.  You can
find their ad in RCM, including some pictures of their scale fuse kits.
Cost is typically around $150 to $250 for the fuse kits, but they're very
good quality fiberglass work.  

Unfortunately this isn't from experience, but I did have several opportunities
to examine the fuselages while in their shop.

Speaking of that, I am, in addition to being a RC model airplane guy, an

tester.  I use an automotive tester with a special adapter for the smaller
motorcycle plug threads.

Has anyone ever heard of a small-volume compression tester for model
airplane engines?  I would think that actually seeing quantitative
values for compression would be a great diagnostic tool for our
motors.  I envision just unscrewing the plug, screwing in the little
tester, and using a starter to spin the motor and get a reading.  You
would be able to tell when a motor was getting broken in, as the
compression comes up to spec, so you would know when to peak the
mixture, and when it was getting worn out, so you could increase
the castor and/or replace things.
