The model is about 1/5th scale, which gives a wingspan of 54”. Peters favourite combination of a 3541 1070 brushless motor, a 40-amp ESC and a 3S 3000mAh LiPo would be the right power set up.
So here we have a model that looks great and is pretty easy to build. It weighs 3 lbs 13 ounces ready to fly. This is one of the nicest, best-behaved models that Peter has flown in a very long time – and he’s had quite a few favourites!

What’s in a Short Kit? – A short kit usually contains, where available, the plan, the laser/CNC cut wood pack, additional wood pack, canopy, cowl or any other available Glass Fibre or plastic moulded items.
What’s in a Laser or CNC Cut Wood Pack? – A CNC or laser cut wood pack contains most, if not all, of the intricately shaped parts shown on the plan, which would be difficult or time-consuming to cut out by hand. It does not contain any sheet or strip wood, which you will need to buy separately. Alternatively, you can purchase an Additional Wood Pack, if available. Our Laser or CNC Cut Wood Packs only contain balsa, ply and lite ply and do not include other materials that may be required to complete the model, such as hardwoods, metals and GRP sheets.
What’s in an Additional Wood Pack? – Our Additional Wood Packs contain MOST of the necessary sheet and strip wood needed to complete a model being built from a Sarik Hobbies plan and using the associated laser cut wood pack, if available. We stock a wide range of balsa, ply and spruce in popular sheet and strip sizes but even so we cannot guarantee to be able to supply all the wood necessary to complete each model. So some additional purchases may be required from other modelling wood stockists if not available from Sarik Hobbies. Our Additional Wood Packs only contain balsa, ply and spruce wood in the stock sizes as used by our suppliers and do not include other materials that may be required to complete the model such as hardwoods, metals and GRP sheet.
