Hi HOOKMUT I have the os 108 in my hellcat and have set the cg about four and three quarters inches back from leading edge . I balanced inverted with gear retracted . Is this good or do i need to change it? please send me you figures and throughs on elevator and ailerons. Thanks TOM

looking real good Luke. doesnt even look like a CMP product anymore. I enjoy your bashing

It is a 1/8th Century Jet Pilot. I would of much rather had Luke's pilot though. But it looks ok adds that last touch.

What paints are you all using for the tri-color(1943 - early 1944 scheme) Hellcat ??? [email protected]

Canopy Question -
Guys, With Lukes Canopy are you manually sliding the main section back or do you have it hooked up to a servo?
I will be attaching mine tonight-
Thanks!!

@warks62;
First off, congrats to this absolutely gorgeous Hellcat. Much better looking than mine, really. What I noticed with your paintjob is the same effect I noticed on mine. In the broad sunlight even the dark blue brightens up quite a bid. Take your time with the maiden flight. Everything must be perfect for that. No compromises.
Good luck

IL-RC, Just sliding mine back manually. Thanks thevirgian should be this weekend.

Randy

Luke,
You are an artists. So can you cast those pilots? Will you? If you will I want 4.

Here's a question for you guys...
When I fly my Hellcat I have a hard time getting a straight and level track. It's very touchy on the elevator as if it is sort of porpoising a little. It's not totally out of control, just hard to keep straight and level.
I've reduced my elevator throws as much as I care to go.
According to the plans, the CG should be around 25mm. Does this sound like a tail heavy situation?

Thanks, Chris

Chris I haven't flown my modified one yet but my stock one did the same thing. I added an extra 2 oz of lead to the nose and made no differnece. I finally put about 25% expo on the elevator and then it was good. It takes very little movement on this plane for a alltitude change. It has a large elevator which I think is part of it. It worked for me anyway.

Randy

Randy what is 25% expo. not being funny just a novice learning terms.

Thanks

Ben

flyfisher431, expo is actually expotential. It slows down a servo in the first part of the movement but full is still full. The 3d guys use it a lot. So long as you have a computerized type radio it will have it in it. Read in your radio manual on expo it will explain it much better than I can but I will try. Lets say a servo moves a 1/4" of travel with 1/4 stick movement. With 50% expo that same servo will only move 1/8" with the same 1/4 stick movement. Now this only approximate not actuall measurements. But as you move the stick further the servo will start to catch up with the stick untill full deflection on the stick is full on the servo think of it as porportional. That way when you want full elevator you still have it but the first part of the stick will be much less sensitive depending on how much expo is dialed in. Like I said the book will explain it much better. Some warbird pilots don't believe in it but I do but it is something you have to try and see if you like it. I only use it on a plane if I think it will help and the Hellcat is the only one I use it on except my B-25 I use it on the nose steering so that it is less sensitive on take off and landing but I still have a load of steering if I want to make a real tight turn.

Randy

Thanks Randy. I definitely try it.

Chris

YES simply out standing and thats the CMP[sm=confused.gif]

AND Bent Metals' too!! love the rivets on both replicas real nice now to ask a question which I'm sure is some wheres in this here thread that being :"How do you do your rased rivets specifically is it RC-56 a form of water based white glue-
Thanks for any answeres and again nice HELL CATS[sm=49_49.gif]

ramcfarland, I just used elmers white glue with a syrenge with a small needle cut off flat and start making glue droplets. Due make a pencil line to follow though. This works great and adhere well.

Randy

warks62,
Don't sell yourself short. That was a great explanation and I'll for sure read up in my manual. I just recieved my new Spekrum DX7 and that is going to be my principal radio for all my new planes. Right now I'm preparing to start work on a GP P-6E Hawk and the Hellcat is the next bird after that. This build thread is a gold mine of information by the time the Cat comes out of the box I'll feel like I've already built two. I'm a true beleiver that experince is the best teacher, even better when it is somebody elses. [sm=idea.gif]

Thanks again

Ben

I use a hypodermic oiler made by Gaunt Industries near Chicago. Website is www.gauntindustries.com . I use the Hypo 25 and a 2 oz. bottle with Titebond diluted 25%.
They cost $2.50 each in quantities of 6-11. This Dave Platt's discovery.

Thanks Hal I will also take a look because trying to come up with the needles is real bummer. I keep hoping to come across someone who is diabetic to get some needles but no luck. I make sure that the one and only needle I have is very clean after use. I see now what the Heroine users go through, LOL!!!!

Guys--I appologize if I'm missing something in using the "threads" here. I've "posted" several questions about putting together the CMP Hellcat and associated 80 " inch Jap Zero. I see many other responses , and believe I may be mistakingly missing / not being able to access a "pile - of -responses" somewhere here in cyber-space if I'm looking in the wrong place. Seems pretty simple, as I look at the title of the aircraft -- ie" cmp Hellcat ", but have yet see anything in response to my questions (and I think they're somewhat intelligent questions...., an expert builder may not think so..whatever..??). The questions have been mainly pertaining to the (1) Sierra retracts installation (heard no answers in reponse to my multitudes of questions/ and advocating input on that area of construction, (2) building up the wing after gear installation (spar buildup, glassing the skin, etc. ) and input on (3) successful use of various priming / painting the aircraft. These are just a few. I am a somewhat experienced builder---but I'm never done "learning" , as with full scale flying...however, I'm at a loss here with where to look for my (hopefully) multitudes of answers I'm awaiting for. There are some beautiful Hellcats here---and want to join in on the fleet of completed aircraft. I'm a better builder than an e-mail/ rcuniverse user---someone please set-me-straight on what I may be doing wrong. ?thx--ed "sark"

Ed Sark, try reading this thread from the beginning you will find every answer to what you are asking here, plus maybe some more that you haven't even thought of yet. There are some great pictures posted showing step by step everything that has been done. Just start at the beginning and you will find a lot of great information. Luke and Hal have posted some great build pictures along with many others. There are some great pics of the retract install with Sierra's.

Randy

Randy at Warks 62--Thank you for setting me straight.....Just read it..( I'm "crossed eyed", I just got in from work this morning----late red-eye) Randy --now I see how I have to go back, way back on the 'thread' to see ,...I was in need of remedial rcu universe help ,...ya just broke the code ...Now----thanks First of all, to individuals who built these Hellcats>>>---commendable work...unreal. Many of the crewmembers, ordinance men, mechanics, aircraft deck-handlers , and pilots / gunners of my Dad's Pacific Carrier, The Yorktown(CV-10) have a keen interest in the emulation of these planes they worked on , flew and strapped ordinance on >>>they would love to see these online, or I can print/ mai the photos if you e-mail em.....l---I cannot get these to go print from RCU ot to frwd e-mail from rcu to them-----If you want to e-mail me photos of your work directly ----you guys do greeeat work here >> and I can frwd to these guys , all in their 80's and 90's. There are pilots of the CV-10 Yorktown from Air Group Three and AG 88, from late '44 and '45 --they would love to see these remakes of the planes they flew....When you talk to '
em at the reunions, the hands start flying through the air, "air action".... The greatest generation.....

Randy--thx..Lukethx..----I just got your canopy kit...radial...great work---Thank you!!!!! Edward A. Sarkisian nlooking for e-mailed photos I can forward to these WW2 vets, guys.... Sarks757 @aol..com

heh Richard L---I have the os 1.2 for the cmp hellcat---would you let me know what you think---ready to break in the 1.20 os fs...lots invested into that engine. Yopu mentioned the Hellcat would be nose heavy with that engine and the alum mounts. Seems though we can always 'easily' move the cg aft>>anyone comment..batteries, etc, to slightly aft of the wing area in the fuselage. What fue tank did you use??>>>>>>And esopecially what orientation didn you mount the engine?> Head at 90 degrees to starboard, or head at "6'o'clock"?? If you ran the engine head at 6 o clock, did you run into hydraulic lock problems>>>??Thank you--Edward A. Sarkisian

heh virginian----i'm finally learnin to reads this rc un thread follow up--copy your read on my earlier comment!!--nnnoooo problem, , man!! keep uo all the good work---sark

heh Fred--What spinner and 3 blade combo you using for the 1.20 os on the cmp hellcat. trying to keep track of what's where, by who, in reponse to who here on rcu. can ya just e-mail me a response--just in this morning---wanted to get to the field today. zero's out--redey. can you just e-mails me--?? [email protected]... having alot of troubel finding responses to multiple ' posts i've put out on sierra retracts, resupporting the spars, if necessary>>??the wing glassing-- have seen no rsponses. i've posted quite a few requests for info--ed sark
