Ap ez twin ? Anything i need to now when adding more engines and things to consider ?

#1
Hey up guys so I've been flying my ap ez ive made she's mega. its my first Successful build that has achieved flight nd given me a platform to leanr so thanks airbpirates for that now I've found foam board so I adapted its wings to give dihedral tips and made it 3 channel with a little 15 quid gyro 2206 2300kv motor on a two cell now I'm wanting to start considering my next step and before i go to 4 channela i really wanna make a terrainer with dihedral tbh I'm in love with the piaggio p166 with its full wing and was wondering if anyone could recommend a good passenger style plane that's in foam board ? So I could adapt it but I also want to consider adding a twin engine to the ap ez as it could be simple and just fun but give us a hand please cos I'm still getting alot wrong and the more I no the better itle be . Chears guys

The Piaggio P.166 has a gull wing and a twin pusher setup. You should start with a straight wing. You have to pay attention to the center of gravitiy (CG) and the wing cube loading (WCL). Take a look at the AP Godai twin setup parts (AP_Godai_Plan_D_Full.pdf). I think it is easy to adapt them for the AP Eazy.

to make a gullwing, takes more effort to make, buts possible. Just eg. check out builds of the Corsair wing, who is a inverted gullwing. The Piaggio P.166 needs scratchbuild though.. thats you should master how making it from just a few drawings/pics, as a 3D picture,
