Choose the engine for your O2B :
This delta trike, full of tricks, is an interesting alternative to existing machines. For those who want light, comfortable, easy to handle and not very gluttonous (this device averages 9 l/h in tandem), the O2B with the Oryx wing is a choice to remember.
E-Props Users Feedback on the O2B : DURANDAL-3
Proud to be the first to try the Excalibur-4 on my delta trike ! Top-notch performance and a nice, competent team.
