RE: CMP Hellcat
 

I am enjoying reading this forum as I have the CMP F6F from Nitroplanes for one of my winter projects. I am interested in the discussions of the Air retracts that seem to center around CJ and Sierra. I'm sure that everyone has an oppinion about which is best. I'd love to see som pictures of either installed in the AC and what pitfalls you ran into during the process. I am also considering talking to Kelvin at http://www.keleo-creations.com/ about a custom exhaust. Has anyone tride a G-26 for a powerplant?

Thanks for any input.

hi,can anybody tell just what flutter will do to a plane in flight.
thanks Fred

RE: CMP Hellcat
 

At first it just makes a gawd awful noise kind of like cards in the spokes, the end results are stripped gears in the servo or something else broken and no elevator control (if it is the elevator and not the ailerons) and then a crash.

The plane would take a big dive on its own when the elevator flutters. I've seen this on mine and on TT Rare Bear.

RE: CMP Hellcat
 

Hi my cat climes with almost no control,also the ele.has alot of play.I had 5 flights with no problems then it started.Is this flutter.
thanks

RE: CMP Hellcat
 

Can you hear and see the elevator fluttering in the air?

RE: CMP Hellcat
 

I didnt notice

RE: CMP Hellcat
 

Hi,
It is quite likely that whatever causes flutter is visiting your model now, and that flutter itself could take place. Keep your airspeed down, check for slack in the model's elevator servo, pushrods, horns, etc. Did you 'Y' your elevator pushrods? If so, you may be getting flexing at the 'Y'. The model gods have given you a warning-find the problem(s) with your elevator system!! Good Luck!!

I'm using the Sierra retracts and this is what I have so far. I still haven't figured out how I'm going to close the small doors yet (they're not on yet). I'm using a 3 1/2" wheel and had to make the opening bigger which meant cutting the ribs on either side of the wheel well and making new short ribs to strengthen the area. You also have to cut down the spar a little to get the retract in (see page 51). The gear doors are from Luke.

Nice job on that gear install.

RE: CMP Hellcat
 

Bigbird, Thanks for the information. I came into a complete set of Robart's from a guy in our club that is selling a bunch of stuff. I've read on here at least one person that used the 615s so since I got Robart: #188 Air Control Kit, #615 100 Degree Rotating Mains, #164 G PSI Pump w/ Gauge, #650 Shock Landing Gear Strut,for the package price of $100.00 (all NIB). I figure if it turns out I can't use it here it will fit some future project. From the looks of your pictures you stripped the wings and are going to do a recover. What do you plan to use? What other mods are you doing? What engine? I've seen the Flap aileron Mod and that looks cool.

Merry Christmas

Ben

RE: CMP Hellcat
 

Thanks Johnny.

Ben,

I'm going to fiberglass and paint. I've got a custom cockpit, drop tank and dummy radial also. I bought a YS 110 for power and plan on a Spectrum DX7 radio. I've built 4 kits and put together a couple of ARF's but this is my first foray into bashing... we'll see.

bigbird

RE: CMP Hellcat
 

Where did you find a drop tank for it? Thanks.

RE: CMP Hellcat
 

Oldscaleguy,

Luke Zollner made a bunch of mods for this plane but he has no contact info. You can check out http://www.zollnermodels.com/ , I believe he sells on eBay occasionally or try posting here that you are interested, other than that I can't help.

RE: CMP Hellcat
 

Merry Christmas to all,


Does anyone have a close up of Luke's cockpit in a finished stage? I'm trying to wrap mine up, but I'm having a problem with the gunsight. Not quite sure how it goes together. If someone has a picture I would sure appreciate them posting it.

Thanks
Gary

RE: CMP Hellcat
 

Gary,

check out post #1205 on page 49. If that doesn't explain it enough I'll post a picture of mine. It's done except for the weathering.

RE: CMP Hellcat
 

Bob,
Did you find a gasser that would work. I would like to go Gas on this bird and have a scale functioning exhaust made by Kelvin at Kelocast.

Let me know what you've found out.

Ben

RE: CMP Hellcat
 

That's what I've been looking for! Thanks BB007. Time to get back to work.

RE: CMP Hellcat
 

Are there any decent mechanical retracts for this plane?

RE: CMP Hellcat
 

No

RE: CMP Hellcat
 

I have to agree , its not thing about mechanicals retracts , its that you will be pushing the maximum weight of what they can take with this plane . One bad landing and you will probably tear them out .
I dont know if the Horizon brand that is used in the H9 Hellcat could take the weight of this plane .

RE: CMP Hellcat
 

Hello bigbird;
Here is my Cat with the mains and the retractable tail wheel installed.

RE: CMP Hellcat
 

Who's Retracts did you use. Looks great :D

Ben

RE: CMP Hellcat
 

Looks great, did you make the tail wheel retract? How did you get it in there, also how are you closing the small gear doors.
