Hi, I've bought a 1.6m slope glider (moulded), however it comes with no real building instructions or accessories, and I'm new to this game and not sure how best to make up a servo tray for the v-tail servos. My only access is through a reasonable size hole under the wing.
There is just about enough height to the fuz to get the servos in vertically if they are in the middle of it, so they'll need to go one in front of the other, or more easily they'd go horizontally across the fuz.
Does anyone have any suggestions for how I can install the servos so they are secure, and yet removable should the need arise / for adjustment. Pictures or links to pictures especially appreciated.

I'd also appreciate it if anyone can provide a secure method for installing the battery / lead and r/x in the nose which I can only get to by shoving stuff up into the front from under the wings - which doesn't strike me as too secure and could cause problems with the cog should it shift....

Thanks.
