That's all I would do. Fine tune what you have. These planes don't last forever anyway, so enjoy the great flier you have.

The low speed stability is really good. Did you adjust the vertical thrust at all ?

The next video better be full of inverted low passes about 10 feet from you :giggle:

Nice job Saurabh.....Can't ask for more than that. What you going to build next???? Be careful with the low inverted passes. That's when you'll bring it home in million pieces.

Hush hush Wayne  ;)  8-)  >:D  The whole idea is to get him to build something even more magnificent  ;D

Yeah, when mine turn out looking good like that, I hang them from the ceiling and never put a motor on them. Then build another just like it and fly it with no paint!!!!

What would you do if the latter model turned out to be better than the former? lol :giggle: . Its very difficult to make exact replicas.

@ Saurabh bhaiya :  :salute: :salute: :salute: {:)} {:)} {:)}. Hopefully one day i can build models as good as that.

Nice flying Saurabh, the performance and speed seem to be better now...........

Thanks Angad.  ;D

Infact yest, I changed the ESC of the mig to Mystery 30Amps ESC with Auto Timing.  :)
Now, it does not click click at low speed which I presume was because of timing.
Infact Mystery has a smoother throttle curve compared to HK SS (as you had rightly quoted) :salute:
Guess this 30 Amps should be good enough. Even the motor is not getting that hot now. But the rpm of the motor at full throttle remains almost the same. ESC goes a little warm at full throttle even on running for 30 secs.

Thanks Rohit. It si not that difficult to make these models. All you need are right tools, material and time and patience. I am sure you can make better :)

I am no expert in building such models but still on my learning curve  ;)

Yeah, foam, tape and glue is about what these models were designed to consist of. Then of course the electronics. I think this is the area that scares many away. Most of the designers recommend a 2200kv motor with a 5 - 6" prop. Then it's pretty much balance and fly.

You can go to http://www.downloadzgalore.com/rcplans/ and download the plans to your computer and see what they consist of.

Have fun...Wayne

Well said Wayne :D

Infact the same plan is available there too. Tomhe's Mig 29.

She is actually a great model to build and fly. And if used the correct size (thickness 5mm) and with some aerofoil (tapering of wing edges) and 2212 motor, she will go from as fast as a rocket to as slow as a trainer. A very versatile model indeed.  The idea should be to make her as light as possible.

Hi Saurabh,

I wasn't sure if you used the Tomhe plan or not but knew it was pretty close. I just don't have any luck with 5mm foam. Sooner or later I always walk out of the field with parts of the nose in my back pocket. I have been using 1/2inch Dow insulation board for all of my recent builds, wrapped in clear packing tape. On those I run a 2826/6 with a 6x4 prop. Not as fast as yours, I'm sure, but to me it's the ticket for durability and I still get unlimited verticle. Also here, I have a wind problem over 12 mph/20km hr most of the time. I don't discourage 5mm at all because that's what should be used, but for those that have less flying skills, obstacles around the flying field, gusty winds, or whatever the case maybe, thicker foams will work if need be. You probably seen the posts of short lived "Overpowered pusher jet. I couldn't get any takers to build a Funjet with me, so I turned it into a spyplane. Check it out: http://rcfoamcrafters.informe.com/forum/scratchbuilding-f11/from-the-over-powerd-pusher-jet-to-slow-flyer-glider-t8.html

Have fun...Wayne

Final i am able to watch these two videos with max buffering speed.
Nice to see  this Saurabh, which i missed that day.....good work...specially the full throttle, loop. cobra and slow speed fly..was fantastic....well balanced

Ashish : try to use the view finder always to capture the video, this will not only keep the subject in the center of the screen but can cancel the vibration and other heart beat pick up, which is easily noticeable in any video. i know keeping the subject in the view finder is difficult in zoom but you can use your second eye to see the subject and point. if you see my captured video with you camera. you will see the difference.
Fly high if you have good set of batteries.....!

Thanks Sandy...

BTW it was Sushmith taking the video. The viewfinder in my handycam does not work..some problem (only white screen appears) so the only option left is the LCD screen  :(

good to know that the motor is performing well with the new esc....adding a 6x4 will significantly improve performance, good luck with your next flight........oh n btw I have managed to fix the cessna, should be ready to fly again soon :D

let me take th opportunity to congratulate you and at the same time commend on your skills and knowledge.  :salute: You are one of the most knowledgable person in RC domain. With the kind of damage to the cessna, I was sure that it was beyond repairs... But you are too good. I like your meticulous build and approach towards the subject.

A true aeromodeller indeed !!!.  :salute:

Congratulations for the repair... This time it will do wonders in air... I can guarantee you that. :D
Cheers !!!
