Questions
Are you a dealer for these makers?
Systems are bought to order through each maker's dealer channel. Where a maker sells only through appointed dealers, the quote names the route and the lead time follows it.
Do you hold engines, motors or radios in stock?
No. Nothing on this page is stocked. Each unit is bought against a cleared deposit for a named end user.
Can a Group 3 airframe be quoted as one list?
Yes. The engine, the EFI, the generator, the propeller, the servos, the radio and the companion computer go on one requirement list and come back on one quote, each line classified on its own.
