It's always best to try moving components around for CG before adding dead weight. Try moving the esc further aft if you haven't done so already. See post #817 for ideas.

The red dots are on the retract extensions.

Flap Installation

Putting the flaps on my H2. Whats the best way to hold the servos on? Hot glue? What kind of tape to cover the wires?

I like using Liquid Nails which is a silicone glue. Blenderm tape is nice and light weight.

I've always used hot glue on my servos in foam planes, never had an issue with them coming loose.

Low to medium temp hot glue does the job of holding in servos.

I carefully peeled back the original tape, then reapplied it and covered the edges with clear packing tape.

Hey guys I put an 80 amp turnigy esc up front and I needed a lot of lead in the tail to get the 4 inch cg. Total lead weight was 2.4oz or 68.4 grams. Is this way to much and will it hinder performance? There wasso many wires from the flaps and retracts that I didn't want to put the esc in the back. I had a hard enough time getting all the wired up into the fuselage. Thanks a lot.

Too much? No. Will it decrease your performance? A little bit, but not a ton. You might consider scooting the battery as far aft as possible. In my V1 I cut away the rear foam 'supports' from the battery bay so I could get the plane CG'ed without needing extra weight. It helped a lot.
Best,
J

Thanks so much. I don't think the battery will go back as the reciever is right there. I forgot to mention I had a 5s in there. Thanks again.

You might also consider swapping the battery and Rx locations.

If you're going to fly it nose-heavy, just keep in mind that you'll need to fly it a bit faster to avoid a stall. If it does stall, it'll lead to a sharp nose-drop - something to watch out for.

The servo wire "mess" is what kept me from putting my esc in the triangle hole. I shortened many of my servo wires to get rid of the excess wiring. This freed up enough room to put the esc in the "tip" of the air intake. I try to always do whatever it takes to prevent adding dead weight.

Dumb question here. For the guys running 5s, are you hand launching? With the extra weight of the lipo and esc, I don't want to lawn dart it. Any advice?

Thanks
