Work begins on my F6F Hellcat

Finally started on my China Models F6F Hellcat which I purchased off E-bay back in December '04.

Cut out the wheel wells and servo aileron positions tonight.

LuftAdler,

Any updates? How about some details too. Engine size, equipment used, mods made to it.

I've been thinking of adding this airplane to my fleet. This is a great looking airplane and look forward to hearing how it flys.

Scott.

OK, this time I think I am really going to finish the F6F. I have had this plane sitting in a box since last December, along with a brand new engine and servos. Had a false start in April, but I think it is finally time!

Today I installed the engine mount onto the firewall. Also assembled the engine. a Super Tigre .90 2-stroke.

Today’s work:

1. Installed the fuel tank. Used clear silicon to mount the tank as well as isolate it from engine vibration.
2. Attached the huge horizontal stab using 30min epoxy
3. Installed the rudder, elevator, and throttle servos. Using Futaba S3003 servos.
4. Painted the cockpit and wheel wells with zinc chromate

Today I attached the tail wheel, rudder, and horizontal stabs along with control horns. Did a few cockpit details and attached the canopy. Attached the throttle control rod and tested. Installed the wing servos, both Futaba S3003. Replaced the original S3003 elevator servo with a high torque Futaba S3010 servo. Also realized that my standard 4.8 volt RX battery is not going to work in such a large plane. Looking at purchasing a 6 volt 1500 Mah rx battery to give me the greatest torque on all servos and longer flight times.

Some notes on this China Model:

The tail wheel is attached to the rudder and is poorly designed. I am interested to see how long it will last. Very difficult to install because you must cut and bend the tail wheel rod after inserting it into the fuse.

Control rods as they are depicted in the instructions are also going to be a major problem. They catch on the internal fuse frame and must be bent in order to take pressure off the rod itself.

6.0v =useless
4.8v=best bet

If your only switching to 6.0 volts to get the extra torque, then your nto using the right servos. Your best bet is to stick with 4.8v and jsut get a larger capcity pack. 6.0 increases the chance of servo glitching.

So 4.8v is standard in giant scale planes?

Finished up a few more items before placing an order for additional parts and pieces I need to continue the build.

Got the rudder control rod installed and tested. Installed the cowl.

If the parts come in this week, I should be able to finish the wing this coming weekend and maybe get a engine break in and taxi test if lucky.

I use 4.8 v on all of my planes. On a plane such as this one, you definetly dont need really high torque servos anyway.

So this size plane is well within the limits of my Futaba 3003 servos?

0.23sec/60 deg @ 4.8V
44 oz-in @ 4.8V

Seems they should be fine IMO. None of the control surfaces are very big, so its not nessesary to have lots of torque, and since its not an aerobatic or 3D plane, you dont need extremely fast servos either.
