Hahaha, it won't even hold a 5000 down. I added a block of foam to the canopy cover to hold a.4000 in place. I removed the strap.

I have several FMS ww2 planes and the Strap position almost always seems to be in the wrong spot aft , if you are gullible enough to not go with the standard 25 to 30% rule for most WW2 planes This will get the new warbird pilots for sure

So is the cg in the manual still good?

Thanks

I am going to fly it with the CoG at 72 mm back. I don't remember what the manual says. I listen to the fellas here. REAL experience from real flyers.

I'm a foam wedge / foam block guy as well...although with my current 109 I only sanded the battery compartment just far enough to make for a tight fit so that nothing else is required...no disasters so far lol

I too cut some foam out just for the fit of a 4000 4 cell Hyperion. I like a little wiggle room in the battery bay for some air movement. Looks like I finally get to maiden this weekend. Its a bit early in the year but the tarmac is slowly melting .
I have pulled this off the rack a dozen times just to admire the thing. One day I have to get into the cockpit and fix that up. Other than that, she's ready to fly.

Thanks Mr Frank. I have 1500 ft so the take off will be cautiously gradual. At least until I get the feel of the plane. The FMS 109 will be less challenging than the Dynam 109. More forward rake and less wing loading. Expo is set at 58% for rudder as well.

Cheers!
What does the pitch mod consist of. I must have missed reading that one. Thanks.

I installed some carbon strips behind my prop on the mount plate to increase the pitch of the blades. I'll start with the 1mm and measure the real unload amps to determine if I need more. The stock motor can handle the added amp load as the P51 has it as well. Speed is fantastic.

Oh, sorry, I did read about that before but have not yet applied it. When I asked, I thought maybe it was a change in the horizontal stabilizer pitch (or decalage), whew, glad it is not. Thanks for your reply.

Not a problem. There is some great advice on this and the FMS P 51 thread too. All kinds of tips to give you more fun.

Cheers

Yet another mothball day for weather. Oh well, I made some pilots. Now, which one looks the most German. No, not the zombie one. He's going in my B25 (Heavy Metal)
