Bad Boy v2 – Step 1 – Tail Servos

First things first. The blank fuselage ready for the elevator and rudder servos. I removed the covering with a soldering iron. The iron melts the covering as a nice seal around the edges without any jagged edges you might get by cutting with a knife.

Fuse as it comes out of the box.

I covered the lead extension joins with heatshrink as recommended in the manual but found it impossible to fit the join through the small gap provided. I had to cut a small part of the balsa away to get it through. The cut isn't visible once the servos are in so appearance isn't compromised. The thing I don't get is the small cutout on the engine end of the servo cutout. The manual says to mount the servos with the servo arms closest to the control surfaces hence the lead also comes out that end. The cutout at the other end doesn't help fit them at all or with the leads running into the fuse.

I found it best to get the first lead connector into the fuse. Before you pull it all the way through, insert the second connector straight after the first then pull them both through at the same time. I found if you pulled one lead all the way through then try to pull the second through it would get stuck on the extension joiner in the middle of the fuse.

After some stuffing around, the servos fit snugly in the fuse with the leads out the front holes.

  1. A friend gave me a “Bad Boy” plane w/o manual. I am looking for the CG location. I would greadly appreciate any help with this info. Thanks

  2. Gary,
    My version of the manual states “The CG location is about 142mm measured from the leading edge of the wing root”.

  3. mattmc, what is the minimum servo spec if using Hitec brand for aileron, rudder, elevator and throttle control this kit? thanks

  4. Not sure what the minimum is but I can tell you I was using standard Hitec HS-311 Analogue servos.
