Magnus Slope Racer 1.5m

Designed by UK expert modeller Jonathan Wells the Magnus is a tough high performance 1.5m (60″) all molded glass and carbon fast sports slope glider that has a great speed range and forgiving handling characteristics. The model looks fantastic with a good surface finish and a practical easy to fit-out design. An electric hotliner version is also available.

The two piece wing is available in glass and carbon layups. The glass version has a fair amount of carbon and is very strong. The full carbon version is about 50g heavier and is extremely strong and rigid and will be ideal for DSing on the backface. The wings are kept in place with a very substantial carbon joiner. The tailplane is removable making the model very easy to store and transport. The fuselage is glass with carbon reinforcement and is a very sleek design. The large canopy hatch gives great access to the long nose, making for a very easy RC installation and easy balancing. There is some space under the wing for ballast, and also pockets approx 20mm x 8mm x 100mm are molded into the wing roots for more ballast (not supplied).

The complete accessory pack includes all pushrods, ply wing servo mounts (for X08 family servos), control horns, a ply elevator fuselage servo mount, and colour coded wing servo covers. See the link below the videos for English build instructions and this excellent Magnus build log by the designer. Also check out the Facebook Magnus group. Note that although the surface finish is generally good the fit and finish of the model is not up to that of a top price European model. Small bumps and fit problems are normal at this price-point.

Recommended Servos
Elevator (10-12mm)	MKS DS6100, MKS HV6100, Blue Bird BMS-126WV, Blue Bird BMS-127WV, KST DS145, KST DS215MG, KST X10-710, KST MS320
Flap (9mm)	KST HS08A, KST HS08B, KST X08H Plus, KST X08 Plus, KST A08H, KST A08, KST X08H, KST X08, MKS DS6100, MKS HV6100, MKS HV6110, Blue Bird BMS-125
Aileron (8mm)	KST HS08A, KST HS08B, KST X08H Plus, KST X08 Plus, KST A08H, KST A08, KST X08H, KST X08, Blue Bird BMS-A10V

The wing is very thin and 8 mm servos are required for the ailerons, and ideally 9 mm for the flaps. 10 mm thick flap servos can perhaps be used but the servo covers will need adjusting. The supplied plywood wing servos mounts have a 24mm servo cut and we recommend KST HS08A (flap) and KST A08H (aileron) servos.

Extension leads required:
4 pcs 20-30 cm ext leads (for receiver)
2 pcs 10-15 cm ext leads (for aileron servos)
2 pcs 25-30 cm ext leads (for flap servos)
