Great news! Thanks Alpha! Just in time for "Warbirds over Grapevine" our fundraiser for Snowball Express.

Not too keen on the battery strap location.........looks like an immediate mod is required for a more central secure location like at the center area of the battery. ;)
How'd that get past ya Alpha??

There are two cutouts in the battery tray for the velcro strap. I use the rear cutout because I don't have velcro on the batteries here, and pinning the narrowest part of the battery is the most secure way to keep it from sliding aft. Users can relocate the battery strap to the forward cutout (which would place the strap just about the middle of the Admiral 4000).

Thats a big old battery bay!

In my models, I often use a big hunk of soft foam to fill the empty space in the compartment and keep the battery from sliding around.

Mmm... 8s. I'd love to know the height of the battery bay under the canopy's locking mechanism...

I'll definitely be adding a 2nd battery strap..

Thanks Alpha... The manual on my A4 has the amended CG as per pic..

[RCjetdude]

That is not the same image that Alpha posted. The reference point was further forward in Alphas post. Let me just double check to make sure.... It looks like the CG is at the same place in both pics but the reference point is definitely different and could potentially lead to errors if going by a ruler.

Great detailed info, Alpha!

I fly the A-4 Skyhawk at 175mm CG range with Admiral 5000 battery all the way forward and no external stores. My finger tips are placed approximately 1/2 inch inside of the wing fences shown below. With tanks and missiles on, I'm at approximately 165-170mm.

Cant wait! Im from the UK so will mine arrive in the US and then be shipped across the pond or will there be a shipment coming to Europe?

Hey Tony, where are you measuring from?

[barron06]

It looked the same to me.

Compare the front reference point in both images.

Check Turbines Rc in France .. They are Freewing vendors & have the A-4 on preorder..

[Jimbobtheflimbob]

i already bought one direct from motionrc since i couldn't bear to wait for shops in the UK to put up the pre order page

Could it be one pic is an Admiral 4000 and the other a 5000???

Compare the two...



Do you see the difference at the front of the wing?
