Does anyone know where in the U.S. you can buy the Richmodel Keecat??

A word of caution on richmodel....I bought a Quicke and long-ez from them. The Quicke has a RH and LH wheel pants. The ARF I received has TWO LH wheel pants for SIX months now I have been waiting for a RH wheel pant !!@!! Several Emails have gone unanswered.

RE: Its Bobcat nice
Now back on track...
I planned to use my JETT 60 LX FIRE... and route the JDE. muffler into the fuse by opening up the hole for the fuel lines. Looks like I will have to lower the engine by cutting the mounts down and carving clearance in the fuse for the crankcase.
After opening the box I found:
8 SERVOS has been a big question and the answer is:
2 Aileron Standard size servo
2 Elevator Mini servo note one servo will need reversing
2 Rudder Mini servo
1 Throttle Standard
1 Steering-nose wheel Standard size servo
Aileron servo pockets are about 16 mm too long for a standard servo, width is correct!
Rudder and elevator servos mount into the tail booms. Horz. stab fits into pockets in each boom ( I hope I got a right and left side). Then held in place with a screw on each side. Directions suggest to glue the wing panel to the fuse. BTW the instruction manual is the non-lingual type.
The airframe weight is about 4 pounds on a bathroom scale. ( NO: ENGINE OR RADIO)
Fuse is rather heavy in the glass work. Formers glued in 100%. Servo tray is doubled for the mounting screws to get a good bite into.
More to come as I dig a little deeper into this bird.

Hey thanks for the info, but can you tell us when you say Mini servo are we talking HS-55 size or HS-85 size. Thanks.

Hey Bob
I have talk to David he said in about 1 to 1-1/2 months . I left him my info, so that he can tell me the price when it come in.
I will let you guys know.
I cancel Nitro models bobcat . Why ,,,,,,, I order it , and it was in stock Then week and a 1/2 later . it was sold out can you believe that. Then a have to
wait 2 months for it ,and the price went up to $169.oo.
I will wait for the bigger one.

Guys, I am in the middle of coverting mine to electric. Does anyone think it will be ok to use just one servo on the elevator. Its only got 1 controll serface. Well I think I'm going to give it a shot. By the way does spinning a 9 X 6 at 30,000 sound about right for this bird [X(]. I should have it ready for the next revvers meet in Oct.

RE: Its Bobcat nice
I am three days into the build of mine [white one]. At first glance it appeared to be well done. Here is what I have done so far;
The booms are to be mounted to the wings with two small nylon bolts. In my opinion, not enough security there. Replaced with steel bolts. The blind nut mount in the front of the boom is not indexed to the boom sides and pulled out when I tightened the mounting bolts. Epoxied back in place. No further problem there. The front mounting hole in the wing for the boom was not deep enough to allow the bold to get into the blind nut. Drilled it deeper. There is only balsa in there so be careful and drip thin CA into the hole to harden it before you mount the booms. Also, the contour of the boom does not match the airfoil of the wing toward the leading edge and will need to be sealed with some white covering to make it look better.
Elevator requires two servos. One in each boom. Hitec 225's fit but one will need to be reversed if you don't want to run one rod on the opposite end of the servo arm on one servo. Not a big deal but a reversed servo would be the way to go. Is it possible to reverse a 225? And if so how? I want to go that route but don't know how it is done.
Fiberglass fuselage is beautiful. Wing tube hole is cut and the front pin and servo lead areas are indexed in the fuse. Very nice paint work for a ARF!!
One aileron bevel was cut way off center. I recut the hinge slots to match the off bevel so I would not have to try to find some covering to match. Seems to be fine.
Same problem with one rudder. Same solution.
I am now on hold until I figure out the servo reverse thing.
By the way my power choices are; Super Tigre .90 or Moki .61 long stroke[I have both]. No decision made yet. I will see how the balance comes out before I decide. I am leaning toward the .90. You can always throttle back right?????
More to come!!!
Anyone else start their's yet???

Tony,
1) you can buy Reversed servos from Hobby Horse or servo city
2) you can Y servo lead with a built in reverser, most have an adjustment to center the servo
3) With a 7+ channel computer radio mix elevator to an open aux channel. You should be able to: reverse servo, set the center position (with sub trim) & set the end points too.

RE: Its Bobcat nice
Is the wing a bolt on, or is it glued on? That is the only thing stopping me from getting one, need to know how the wing mounts for transportation to the field.............
#69
RE: Its Bobcat nice
The wings dont have to be glued on. I drilled and tapped a hole in each half so I can secure them with screws. Again I dont see why you need 2 servos on the elevator. Its only one surface and a small one at that.
This plane will break down very nicely for transportation. I should have mine done in 2 weeks and will post pics.

RE: Its Bobcat nice
I wonder what electric set up would be good for this, I am really not liking the idea of exhaust all over my investment
< Message edited by AGR413 -- 8/18/2006 12:59:16 AM >
For an electric setup, I've had a lot of success with the following power systems for 46 size planes:
AXI 2826/10 (2826/8 if you want more speed, but higher amp draw)
Phoenix 45 ESC (Phoenix 65 if using a 2826/8)
PolyQuest 4 Cell 4400 lipos (dpending on prop, should give you about 10min flight time (cruise) 6min (full power).
www.Hobby-Lobby.com is a great source for info about electric conversions.
If you're new to electrics, it can be a bit expensive initially (lipo's are pricey and need a special charger) but in the long run, IMO,you will be very satisfied with electric over glow.

Prop strike might me a bigger problem. I see they use a 3-blade, but I have flown a bunch of pushers and I don't recall a 3-blade pusher. Maybe there is one.

Are my eyes playing tricks perhaps?

RE: Its Bobcat nice
I concur. 3 blades are the way to go on this bird. It give you an extra inch of prop clearance. For those of you that want to go "all out", Dub Jett offers a counter rotating cranckshaft on his engines (the engine runs backwards) for only $25.00 extra. This will allow you to use any regular prop in a pusher configuration. Will also open up a wide array of prop choices.

The wings glue on. These are two wing tubes that serve as joiners, one fat one
and one thin one. It would be possible to rig the wings ups with better wing
tubes and bolts, but it would be risky.
>>>Edit:...in pic #1, "AB" means parts A&B of epoxy.
