0. Introduction Heat management is essential to jet powered UAVs or models. The safety of the vehicles and property or persons on the ground can be affected in many ways by heat related issues. Bush fires ( fire bans in the summer ), direct burns due to jet efflux/ hot parts exposure, airframe destruction in flight, loss of control due to airframe deformation or electronics burning, airframe explosion due to jet pipe implosion are some examples among many others. The main source of heat in the model is obviously the jets engine. This type of powerplant is basically burning the fuel as hot...

0. Introduction   This tutorial is following the one made by Joe Grice that you will find just below this article. This presents different techniques from the one used by Joe. The result achieved with my techniques will be slightly different. The panel lines will be more pronounced and the general aspect of the aircraft will be rougher. 1. Aircraft preparation   One nice thing with Flite metal is that it sticks better to mirror finished surfaces. So I usually just wipe the whole aircraft with an acetone dipped cloth to get rid of the demoulding wax. Then I fill...

The following is a step by step tutorial on applying Flite-Metal.   An easy way to remove the metal from the roll without wrinkling.   Tools required. Sand surface with 320 grit . Hold against flat surface while releasing to avoid curl. Burnish/press onto surface. Lay masking tape right up to edge of panel. Overlap next piece onto tape. Use ruler and #11 blade to cut, but leave tiny lap. Burnish edge down. Sand lap edge to remove overlap. Now you have level butted edge. Sand overall with 320 grit.                                                                                                                                                                                                                                                                                                                                                                               Use straight edge and #2 mechanical pencil to...

We are proud to introduce a new innovative type of product to the market.These are aero grade structural carbon fiber and basalt fiber sheets. I designed these sheets specifically for jet modelers.The very specific thing about this product is that it is designed for both structural reinforcement and to improve the look of the internal structure. As such it features one face with a nice satin look and one face with a ready to remove peel ply fabric.     The peeled side will ensure the absolute best bounding characteristics onto any type of material used in a jet and...

 There is mostly one source of heat in remote control jet: the turbine. Two types of heat will be found: readiating heat and direct exposure to the jet efflux. The first one will generate moderate levels of heat, rarely above 100c/ 220F. The second one could expose the equipment to temperatures up to 700c/ 1300F. Although it can be relatively easy to hide the loom from hot areas due to radiating heat, it is much more difficult to protect it from jet efflux. Radiating heat protection is just a matter of routing the loom appropriately and choosing the right cables....
