RE: Nitro models pusher Bobcat?

Sorry for the delayed response, been offline for awhile. Yeah, the servo bay needs to be slightly enlarged and 3/32" shims added to the surface for enough depth to clear a standard servo. Pretty easy...

RE: Nitro models pusher Bobcat?

Any standard size servo with decent torque will do. I have an HS-475HB in mine, 76 oz. torque @ 6volts.

RE: Nitro models pusher Bobcat?

No need for any type of booster. You're not using any high current servos here and even high perfomance digitals don't need any booster, just heavier gauge wire. Giant scale planes have servo leads...

RE: Nitro models pusher Bobcat?

Pit-Viper 1,
With the receiver mounted just behind the nose gear former you'll need 24" extensions for the aileron servos and 36" extensions for any servos in the tail booms. A "Y" connector will...

RE: Nitro models pusher Bobcat?

My original Bobcat has fixed gear with an OS .55AX at a total cost of around $600. This is with a single HS-475HB for rudders and a single HS-475HB for elevator. Add about another $160 for retracts...

RE: Nitro models pusher Bobcat?

I would tend to believe this is normal behavior for a foam wheel rolling at speed. If the nose was getting pushed down that hard the plane would likely never leave the ground. Either way, I can't see...

With a slightly positive AOA the nose wheel should not be "pressed" at all unless the pilot is holding down elevator during the takeoff roll.

RE: Nitro models pusher Bobcat?

I don't have the Retract Ready version but I would think it should be relatively easy to cut the slot in the bottom of the fuse slightly longer to accommodate a taller nose gear. General rule of...

RE: Nitro models pusher Bobcat?

Two problems with this choice. The 12.25x3.75 APC is a Fun Fly prop designed for lots of torque at lower speeds and it is not available in a pusher version that I am aware of. ;)

RE: Nitro models pusher Bobcat?

Mine is pretty close, probably 1/2" or so. I do think this adds to the noise factor on this plane, it's by far the loudest two cycle I own with a stock muffler.

RE: Nitro models pusher Bobcat?

I don't think metal gears are really necessary but a standard size servo would be much better than a mini.

That's odd. A 3004 should have plenty of power for the nose wheel especially since it doesn't need a lot of movement and that gives the servo quite a mechanical...

RE: Nitro models pusher Bobcat?

Depends what you're flying from. I would not use a micro servo for grass as the nose wheel has the potential to easily strip the gears.

RE: Nitro models pusher Bobcat?

Macs Pipes list the same part number for a header that fits the 61FX and the 75AX so I assume the hole spacing is identical. It's 42mm on my 61FX.

RE: Nitro models pusher Bobcat?

Drill holes in two small squares of 1/8" aircraft ply to fit the antirotation rod and glue them to the inside of the fuse in the correct position to get rid of the slop.

RE: Nitro models pusher Bobcat?

I think an OS .46FX will fly this plane if you have no other choice, but the power to weight ratio is such that it leaves almost no margin for error. You will likely not have the power to get...

RE: Nitro models pusher Bobcat?

I'm not a fan of gluing the wings on this plane for the simple reason of maintenance and/or repairs. Servo mounting is pretty straight forward and to be honest the manual isn't really a lot of help...

RE: Nitro models pusher Bobcat?

There have been a few reports of the Bobcat 50 being flown with a .46FX but I have to agree with Meekskin, you will likely be disappointed with the performance. On the wing attachment question, I...

Nice looking model. What is it your friend needs to know from the Bobcat manual? Not really a lot of info needed once ya have it put together but I'm sure someone will post anything he needs to know.

RE: Nitro models pusher Bobcat?

Not knocking your GMS and I can't say for sure because I've never owned one but in my opinion you can't compare a GMS to an OS. The specs on the GMS .76 state the practical rpm from 2000 - 13,000 but...

RE: Nitro models pusher Bobcat?

I don't think the OS .75AX would be a good choice due to the extra weight and the fact that you probably wouldn't be able to prop it correctly on this plane. Can't go wrong with the .55AX, APC 11x7p,...

Make sure your engine is tuned and running reliably. If I remember correctly you were having some problems with the engine before the first mishap. This is not a good plane for an...
