Hi,

I found some specs on the Limbo Dancer [link=http://www.bmaps.net/reviews/limbo/limbo1.html]here[/link].

Aircraft Type: Fun Fly
Manufactured By: Balsacraft
List Price: RRP £49.99
Available From: Ripmax Stockists. Tel. 0181-804-8272 for Details
Undercarriage: Tail Dragger, Skid at Rear
Wing Span: 51"
Wing Chord: 14.3/4"

I would use a geared Kyosho Endoplasma car motor to power this 3lb plane with your car packs. In fact, you may want to use the same system often seen in a stock E3D by GWMP [link=http://www.gwmp.net/]here[/link]. It packs plenty of power for very little cost.

Good luck!
