Re: HK He-162 Wow, I just checked the date of this post, 2014, wow. This little jet has been hanging in my workshop for quite some time. Lately, I took it down and checked it over. Basically, took it apart. Replaced the wimpy 5 bladed factory supplied 64mm EDF with a newer FMS 64mm multi blade EDF, quite a bit more power on tap now. Then, filled the predominant dents, bruises and seams with drywall compound and sanded everything smooth. Then a coat of latex paint and a quick sanding. I didn’t want the standard German paint scheme but not much to choose from, then I came across images of a HE-162 that was tested by the RAF after the war. They repainted it and decked it out in RAF insignia. Now, that’s a bit different, huh. So, from those images, I got the paint figured out and painted it up to represent that aircraft. I made my own decals and applied them tonight. I’m pretty satisfied with the results, it won’t win any contests but then it wasn’t intended for that. |

Re: HK He-162 We re-maidened this tricky little jet today after I repaired it.No landing gear this time, hand launched it. Ted did the honours and certainly had his hands full trying to keep it in the air, even though it is a very light model, it's a bear to fly, particularly in the turns. With the thrust line so high on the model, it wants to push the nose down. But, Ted is an excellent flyer and managed well. The landing was perfect as the model flies straight and true when the power is off and it's not turning. Once I strart flying it, I can see it will have a short life........ |

Re: HK He-162 Decided to remove the landing gear first off and make it a bungee launch model. Less drag and weight. Fashioned a new nose section and epoxied the stab back together. Plus, added a 1/8" plywood spar. Will apply the latex primer and grey paint later after I cut the recess for the battery. |

Re: HK He-162 The test flight was 90% successful. Takeoff was fairly smooth, didn't jump off the runway, climb out was good, needed quite a it off aileron trimming. Flew pretty good once trimmed out. Seemed to have enough power too. And that was the 90% Coming in for a landing, turned onto base leg, looked like a wing tip stall, flipped over onto its back very quickly which then turned into a dive that could not be recovered from. Into the bean field it went. We figured, with the stubby wings and the weight of the engine pod being so high up off the centreline, it could have been the reason for such a violent maneuver. But it shall be repaired, just the nose in front of the canopy got destroyed, and the stab broke cleanly, so simple epoxy fix for that. You gotta love these little foamie planes...... |

Re: HK He-162 My test pilot, poor guy....... The T-pins are just holding the canopy in place while the Formula 500 glue cures, then they will be removed. You cannot use tape of any kind to hold it in place as the paint will come off with the tape. |

Re: HK He-162 For once, I tried to build one of these as supplied. I test fitted everything first, spun the motor up, just to make sure it would work, it did. A little out of balance at low rpm, but after 1/4 throttle, everything smoothed out. First, the manual, except for showing you the location for the CG, is an absolute joke, a waste of paper, the whole assembly instructions consist of 12 small pictures with one or two lines of text, and they do not seem to be in any particular order of construction. The nose strut has the flat land ground on the wrong side so the strut will spring incorrectly, will change that by re drilling the collar and tap threads on the opposite side.then I can spin the strut around 180 degrees an lock it into position. The rear of the battery compartment had to be ground away so the 1500 mah battery could fit properly. Found the elevator and one of the aileron servos were not glued into their positions, so five minute epoxy fixed that. I used 5 minute epoxy throughout the assembly. The screws to anchor the aileron control horns were not long enough, so epoxied the control horn and the screws into position, worked really well. One of the ailerons was attached improperly, the upper surface was way above the wing top surface, so cut it out and reattached it with epoxy. Also, the aileron control rods were about 3/8" too long so they had to be trimmed and new Z bends formed. The motor and supplied ESC seemed to work pretty good. The impeller looks like a GWS product. If I find it too under powered, I'll swap it out for a 70 mm Change Sun with a Mega motor. Going to stay with a three cell setup as I don't want to make the model so out of balance that I would need to add lead to the tail. The access hatch on the bottom of the model fits very snugly but I glued a thin strip of Velcro that is sometimes supplied to hold batteries in place. I can now pull the hatch open by pulling on the fabric tab that hangs down about 1/2". I think I'll fit in some rare earth magnets to hold it in place though. The model does not have a pilot figure, but the detailed Mig-15 pilot from Hobby King for their red or silver fibreglass Mig fits perfectly after some minor grinding on the butt and knees. The red plastic intake lip and the canopy have to be trimmed to fit properly, they do not indicate this in the instructions. I attached the intake lip with epoxy and the canopy with Formula 500 canopy glue. The supplied landing gear seems quite sufficient, holds the model up fairly firmly and except for the issue with the nose gear strut, seems to be a good design. The supplied wheels are firm foam items, and they are not out of round, spin nicely on the axles. The main gear are torsion style design. They attach easily with the screws supplied. All in all though, the model looks pretty good, the foam parts actually fit together very nice and the supplied hardware is acceptable for this type of inexpensive model. The foam is a very high density styrofoam, so if you hit the ground hard, you might have a pile of popcorn. Taxied it up and down the street adjusting the nose wheel to track straight, was quite stable and at higher taxi speeds, didn't really bounce around a lot. Now, it's back to the F-18 |

Re: HK He-162 It's still in the box, never had time to put it together. I'm on my way back home from southern California, with it and several others. Hope to get it thrown together once I get home. |
