    Very Interesting. I have a yearning to make a micro four engine plane but was thinking the electronics looked to difficult, a conclusion your earlier videos didn’t dissuade me from. 
     

    still looks like quite of electronics weight to get it working what’s the weight of the kit?

     

     

    Weight is absolutely nothing!  It's 100g all up weight with 200mA 2s.  One tiny little BEC,  two brushed motor esc's, 2 x 2g servos, 4  x 8520 brushed motors, FS2A rx   Go for it!

    I had heard, in the early days, of brushless motors that you could power more than one from a single ESC so I tried two micro brushless motors in parallel on one ESC and found that everything got really hot so I concluded this wasn't the way to go. It must be to do with the motors not running perfectly in phase with each other and confusing the ESC. 

      Yes, doesn't work with brushless, I also tried it in a twin I built.  As you say confuses the timing. Needs two esc's and two channels, and the good thing about that is you can set up differential thrust!

    I built one of these small cheap foamies several years ago now. I’d seen the small FX702 chuck gliders in Lidl among other places, and looking closely at one, came to the conclusion that it ought to be possible to remove the separately moulded canopy and scoop out whatever foam was underneath to create a cavity for the radio gear, battery etc.. And then cut the fixed control surfaces loose to liberate them from the wing and tail mouldings.

     

    A micro receiver/brushed ESC, two micro servos and a small coreless drone motor later, this was the result (see pics). It flies well for about two and a half minutes on a 500mAh 1S lipo.

     

    The challenge was getting the thrust line of the motor correct for neutral handling, but on a calm day now it flies very well outdoors. I tried it a few times at my club’s indoor sessions, but it was a bit too fast and got banned!

    Interesting, I've been messing about with a mini Lidl  and a rechargeable motor from a foamie biplane free flight cheapie.  But only as free flight. As you say, thrust angle is the hard part to get right.  I discovered that when I built a pusher version of the standard size Lidl glider. The advice online didn't work and thrust line had to be much higher than suggested. Yours is higher still!  

    Re the small gliders, I guess you haven't seen my 4 motor version that I have finally sorted?  100g AUW, 200mA 2s and loads of flight time. 3A BEC, 2 brushed ESC's

    Great build , never get tired of peoples different ways of achieving flight with these kits . Everything from a glider to a biplane version somewhere even one with an EDF drive. Keep up the good work .

    Just a small point I wonder what the ratio of children to modellers of a certain age is buying these from Lidl.

     

    They are just so good for experimenting with.  And dead cheap, plus easily repairable with a hot glue gun.  Must say though after 15 or 16 RC conversions of the full size one, and 6 small ones, I'm running out of ideas now.

    I'd bet mostly adults!  😁

  5. My Lidl Easy Rider Trainer is now finished. It's my no 16 big Lidl build, my first high wing design and it flies like a dream. Quick build blog here, and full maiden is linked at the end.

    Didn't take long to build, trickiest part is hot glueing the top wing on and getting if lined up in 3 planes, but you have time to position it as the glue sets. The intention was zero zero with the slot in the fusi. It's my first green Lidl, this years colour, though I wouldn't recommend green for a beginner plane as it's not very easy to spot when you accidentally put it in the bushes! (Crash 😉)

    I admire your stamina working away at getting these models to fly. Goes to show that one doesn't have to spend wads of cash on the hobby in order to get plenty of fun and reward from it.

    Electronics will often do some weird things if not supplied with a decent power supply for the job required, and your demo is a clear illustration of just that.

    I guess I like the challenge, plus you learn a lot. Very satisfying when you get a result too!  Was pushing it a bit with 4 brushed motors on a small 1s ,  though since I've put that 600mA 1s through a few charge cycles in my tests it has improved a lot.

  7. A while back I built a mini-Lidl cheap foamie 4 motor plane with the idea of using differential thrust for yaw control instead of ailerons. It was a fail. Converted it to aileron, but it was still uncontrollable. The flight tests are here. And no, it wasn't a mix on my TX , and CG was OK. 😉 I was very surprised when my tests later revealed a problem I'd never seen before! But no surprise why it was such a pig to fly though. A bit of a lesson here.

    Is your question rhetorical or real?  
    if real, does the plane glide? Try a test glide first. 

    Test glide was OK, but it was a bit nose heavy. That,  plus very gusty wind didn't help. I re-glued the wing and did a quick test in my garden and after a little trimming it flew straight and level.  Need a good light wind day for a proper test! 😏

  9. Something a bit different from me this time. I was sent this little twin-rotor beginner helicopter for review and it's fun. I've got a few small helis, but I've never seen one with a missile launcher on it before! It's the WL V398-C Missile Aircraft, 6 axis gyro, altitude hold, which works well and it flew nicely, quite stable. It's described as an indoor flyer but I flew it outside on a calm day and it was OK. Could be fun if you had a mate with one, you could have battles shooting missiles at each other. My test flights are at 5m16s including an outdoor test and landing pad challenge! I got it from Razordon who are big helicopter sellers, but seems to be available in a few versions under different badges from £30 to £40.

     

     

  10. After 14 Lidl cheap foamie RC conversions, finally, here's my first Lidl pusher! Can't say I've had much success with pushers in the past, but after going against the online advice of the desired thrust angle and changing it to more like my Bixler's angle she flies well. Test flight is in the video as well as build details.

     

     

  11. Windy day at my strip, but I'd planned to test return to home on a flight controller I'd installed, so I went for it. I'm new to this kind of technology and was feeling a bit anxious, hence I made a mistake.  The idea was get some height, position aircraft well upwind, and first off hit 'loiter' and then check the fpv signal on some goggles I'd brought with me. Trouble was, when the plane was a long way off I flicked the wrong switch on my tx (as I didn't dare look down at it) and before I'd realised my mistake the plane had flown away.  I'd lost sight of it! Sick feeling in my stomach as I gazed into the distance, plus a real panic moment. Would it actually work? ☹️.

    Some nice aerial footage in my video.
