D3A Help requested.

[Marabekm]

Hello all. I have been flying the Ju-87 dive bomber for a while and just recently started flying the D3A. I need help with a few things.

1. How do the Internal Systems Indicator and Mixture indicator gauges work? I have yet to see the needles move and have no idea how to read them even if they did.
2. What on earth is the purpose for the gear indicator in a fixed gear aircraft?
3. Also while flying the pearl harbor campaign mission I noticed the other vals have a waypoint speed of 216 knots (400 km/h). This is much faster than my val is even capable of flying. Is there anyway I can slow them down.

Thanks for your help.
