The magnificent Fournier RF-4D kit by aero-naut is a work of art. The fuselage is completely moulded in fibreglass with pushrods installed - and what a size it is - see photo.

We are talking here about a super-scale model of 2.815m wingspan weighing in at about 5kg.

The wings are foam cores sheathed in obechi veneer, with the ailerons already hinged.

All of the detail is added with fibreglass, ABS and butyrate moulded parts supplied with the kit. The accessories pack is staggering with all conceivable parts supplied. The accessories include a retractable main wheel with all the retract gear - mechanism, pneumatic ram, air cylinder and hoses. The double-blade, scissors action spoilers are also supplied, as is the instrument detail for the cockpit.

Recommended power is an Actro 24-5 outrunner motor on 16-20 cells each - or 5S-6S LiPo - swinging a 14x8" to a 16x8"" prop. The Actro 24-5 is a 435 kV motor of 50mm diameter and 58mm length weighing 350g. Any similar motor could be substituted, for example a Scorpion 4035-330Kv with a Scorpion 90SB controller OR a Hyperion 4035/10 with a Hyperion 80A OPTO controller would be suitable. Also check the MVVS motors as another alternative.

A 50A controller would be suitable if you keep the amps low, but an 80A would allow more experimentation with prop size and a larger amp draw to optimise flight characteristics.

Wingspan - 2815mm
