Don't wake a Tiger until you've factored the teeth




After the sweepstakes it's been too quiet!

Decided to build something  Giggle Giggle  Again! One of those fits of masochism which aeromodellers periodically suffer from  Wink Wink

Regal Bipe adapted from plans on RCGroups

Brief Specs: Span 36" Length 36"
Chord 11/9 Tapered
AUW 1.1 Kg (about 200 Grams overweight  Roll Eyes Roll Eyes)
Motor/Prop: 3536-1100  12*6

Regal Bipe 3D from Depron/Foamboard

Don't wake a Tiger until you've factored the teeth



I had these aileron pushrod tubes for over 10 years. Finally found a use for them  Grin Grin

The ESC sits below the 4 square

Used 9 g MG Servos for Rudder/Élevator, and a single 17 g servo for the Ailerons

Don't wake a Tiger until you've factored the teeth



Thanks Doc. I have so far come accross 3 types of Depron

1. Compressed foam, called biofoam. Brittle, lacks toughness, but very light. Can be improved a little by putting a layer of clear packing tape. I've used this in the top of the Kfm wing

2. "Depron". Biofoam with a very thin layer of polyester skin on both sides. Stronger than biofoam but light (heavier than bio). Hoever linited strength. I've used this for the main wing

3. Foamboard: Biofoam covered on both sides with a layer of thick, strong paper. The strongest of the three - and by far the heaviest. Building with this always puts the model wide over the scale. Used it for the fuse and tail feathers

Thank you

Available in Delhi at Sitaram Stationers, Suoth Extension Market Part 1. They have another branch in Lajpat Nagar

There is a technique for creating bends in Depron. See this http://www.rcindia.org/electric-planes/my-first-foamy-scratch-build-baby-blender/

Good luck
