hey guys,is there much of a diff.between a new cmpro cat arf and an old one,things like mods or updates.
thanks

I like the above pics. Is it possible to do the work with out take off the covering? I’m not planning on glassing the wing. I was hoping to minimize the work. Is there any out there who has done it that way?

I'm using Century retracts...Is there anyone who has done the cutouts for the retacts without removing all the covering?

If you were carefull it can be done. I would use a thin diamond blade in my dremel and make the cuts down the side where the rails were to be glued in and then remove that balsa. Now make the mods needed to the bay as necc to install your gear and some good hardwood blocks. What I did on this one was remove the existing ribs on each side down to the ply floor but no lower leaving the ply floor which is actually not the floor since the wing is upside down at this point. Now make the hardwood blocks for the rails. Now that these are made make some new ply ribs but make sure that they fit good with good contact all around these will be glued in beside the rails. Now before I glued anything in I made sure of a good dry fit after that I glued in 3/8" and 1/2" triangle stock anywhere I could to beef up the area. Now I glue in the ply ribs making sure of plenty of 30 minute epoxy especially at the front and rear of the rib where it attaches to the spar. After that is setup I glue in the hardwood rails making sure that all areas that contact wood have 30 minute epoxy on it. Now if the blocks are very true then since the ply floor is still in you can use that to glue to and it should be square to the wing so that the gear should be sitting at the correct angle. If you do all this carefully all you should have exposed is a bit of ply on each side about 1/8" that you can take a brush and touch up. Just use your imagination and your preveous experiance it isn't that hard and it will be much stronger in the end. Oh and have paper towels ready already torn so that if you get glue on the wing you can get it wiped up right away. Hope this helps hard to explain perfectly.

FRED I see your thread response on the gear--I have the sierra---any toe in toe out adjustment -or installation tips....ed sark [email protected]

anything on the gear installtion on the hellcat you can tip me [email protected]

Hi Sarks757, post #1968 shows a good pic of the blocks for the gear Im using a very hard wood dont know what kind but very hard just about reinforced the whole gear bays.My gear is on its way back to sierra I bent them bad in a crash and now making a new cat old one gone.As far as toe in or out none just install them and you should be alright.

Fred----I remember your plane welll,..what happened??. Try to land in a "lUfthansa" x-wind?? I've been flying + 90 hr/ month (UAL)---time away =360 hours/month.. there's been no time to think or build., But, recently, have been bringing much RC info on-the-road with me.....ie: gear installation info from rcu from 1 1/2 years ago!! I will research thread site ## you recommended. How about a roast beef sandwich at The Crows Nest?? 201--401--6951. we'll talk.... You're with CAL, right??

I'm "on fire" to get going on the F6F--just spoke to 4 -5 "Air Group Five " pilots of The Yorktown (CV-10)from 1943---original Air Group on The Essex Class Carriers in the S Pacific. Spoke to my Dad about initial flight ops on the carrier, April, '43----GOTTA BUILD!!!! Ed Sarkisian THANK YOU FOR THE HEADS UP ON THE INFO!! God Bless....

attention----attention---I know the pilot of Hellcat in your thread photo --aircraft '5k". He's a good friend of
my Dad .
flew "5k". THAT IS AN "AIR GROUP ONE" MARKING, THE "TOP HATTERS" OFF THE USS YORKTOWN (CV-10) IN 1944.

"5k" flown by my Dad's friend ,CAPT. MICHAEL ALEXATOS---AN AWESOME INDIVIDUAL. HE HAS MACULAR DEGENRATION, AND I HAVE NOT BEEN ABLE TO REACH HIM BY PHONE FOR WEEKS+. HE LIVES IN SANFORD , FLORIDA. HE WOULD LOVE TO HEAR FROM YOU--I HOPE AND PRAY HE'S OK. HE LANDED ON THE YORKTOWN...AWES,...YA GOOTA HEAR THE STORIES. THESE GUYS ARE THE GREATEST GENERATION. CAPT ALEXATOS "THE MAD GREEK" as HE TELLS MY DAD, WROTE SEVERAL BOOKS--HE SENT TWO TO ME. THE BOX COVER ON THE AIRFIX F6F 1/72 SCALE KIT IS HIS PLANE "5K"ON THE TAIL. THE DIAGONAL WHITE HASHMARK INDICATES USS YORKTOWN AIRGROUP. MY DAD IS ORIGINAL CREW--MARINE ANTI-AIRCRAFT GUNNER--1943-1945 ON THE YORKTOWN. HE'S IN HISTORY CHANNEL----LOVE 'EM....I'M BLESSED.

fred---#1968--excellent pictorial of gear block buildup--THANK YOU-!!-ed sark

Luke--I don't know if, when you get this--but I was one who ordered some of your parts for the F6F Hellcat. I just want to say, I find the canopy, cockpit kit, etc great workmanship, and am very glad to be part of the "crowd" to get some of the goods, while they lasted. No---I haven't touched the Hellcat at all---MUST get going on it---tough to do from a hotel in Los Angeles,California,...so, I study on "how to's "....Hope you're doing well in this Hobby Business.....still making parts?? All Best-----Edward A. Sarkisian

Well, I acquired one of these in a trade last week, new in the box - as well as a YS 120F, Robart rotating retracts (probably some other goodies in the box - haven't had time to look) (went out at lunch - looks like I have a retractable tail wheel too)

Up to about page 15 reading this thread - I'm sure I'll gain a wealth of knowledge. First nitro plane since I got back into the hobby 4 yrs ago - been flying electric so far. My buddy has the CMP Zero, I should have some fun chasing it around.

Do you make drop tanks and bombs for the Corsair 60 size ? I'm reading the post and seen your remarks about the hellcats and i have a top flite Corsair with intiror kit and dumy engine i hope to build into a show plane and still fly it. I planning on building a hellcat to go with my P51 and Corsair. I hope to build and fly the full set of WWII fighters.
Anyway Thanks Jim S
Once a Marine allways a Marine...

Good to hear from someone on this thread. My Hellcat (from Nitro Planes) is still in the box but I'm collecting the components. I got a really good deal on it from a guy at the AMA show last Jan. He had bought it but had to many other projects. It came with Century retracts... $225 for the plane and retracts. Also I bought a hydraulic unit from a friend...$20 below cost. I plan on putting a 125 Saito in mine. It's a good engine with all the power this bird needs. I want to keep the weight down. The guy I bought it from an old time buider said it best not to add to much weight to war birds, they fly best without it. A lot of people on this are doing a lot different things to theirs but I plan on keeping it simple. I think it looks great the way she is but I might change some of the grafpics.
Good Luck with yours.

Once you're done Shubova, we'll have to hit Whittier Narrows and fly. Worked on mine a bit last night, got the wing hold down bolts in, belly pan tacked on. Onboard glow driver showed up yesterday, will probably work on that tonight.

OldFart,
That would be great but it won't be happening soon. Got another project (GP Supper Stearman) to finsh. I haven't been to the Narrows in years. I had bad experience there...to mean crazy people. Maybe on a week day might be better.
Thanks for the offer.

What onboard glow driver are you using? I have never used one...is it relieble?
[8D]

Shubova,


I had a cmp hellcat with sierra, retracts os 1.20 inverted with onboard glow painted in tri color flew great wieght was not a problem.I ,m making one now the same way.I stalled on landing and cart wheeled it and totaled it,man it was a good looker and flyer, it flew great.Loved it so much I had to make another.Also have and flying now the great planes super stearman with a g-26 also flys and looks great.So dont worry to much about the weight with a saito 125 you should be fine.
good luck,
Fred

RC McDaniel - my first time for one, so I'll have to let you know.

Opinions - I'm at the stage where I need to find a home for the 2000mah RX battery and the onboard glow driver (which also has a battery) - I'm considering locating them above the fuel tank, in the area "below" the servo tray (below with the fuselage inverted)

Were there any big CG issues with the Hellcat? I know my buddy's A6M Zero took a lot of nose weight.

Keep the weight as far forward as possible you will need it.

Thanks. I'd planned on locating the RX battery and glow driver module "under" the servo tray anyway (cleaner) - but this just reinforces my belief. YS 120 will help

HEY GUYS i PUT MY 6V 2200MAH BAT JUST AFT THE FIREWALL IN THAT DEAD SPACE ON THE BOTTOM OF THE FUSE.AND THE GLOW DRIVER BAT JUST AFT THE SERVO TRAY WITH A TIE WRAP HOLDING IT TO THE SERVO TRAY.
FRED

Fred, what motor are you running, and did you have to add any weight to achieve CG?

Jeff, Im using and os 1.20 inverted and the c/g came out on the money
