David Soper Posted August 11, 2016 Share Posted August 11, 2016 After having issues with this model ... Century replaced my faulty model. They have been ok with my issues and tried to address them. model test flown by club instructor and yet again tail wheel broke, was just a light heavy landing something i expect to happen while learning. We have very experienced instructor and he said tail wheel is not strong enough. He is making a skid mod .. this is a £200 model as was suggested by club member why not make it carbon fibre as takes a lot of stress, instead of £2.99 plastic Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted August 11, 2016 Share Posted August 11, 2016 Tail wheel is a known weakness, I fixed mine by gluing in some spruce at the tail end and then using a commercial tail wheel, I can post a picture if you like. The design of the molding is poor in that the reinforcing stops just before the rear retaining screw which creates a large stress raiser so it breaks there. The design needs to be changed so the "bracing" extends past the rear retaining screw. Quote Link to comment Share on other sites More sharing options...
David Soper Posted September 7, 2016 Author Share Posted September 7, 2016 Can anyone tell me what the mounting plate is for behind the undercarriage? is it an option to put wheels further back? Quote Link to comment Share on other sites More sharing options...

It's for if you have floats, it's the rear mount. Quote Link to comment Share on other sites More sharing options...

David Soper Posted September 7, 2016 Author Share Posted September 7, 2016 Thank you Frank, flyer at club thinks undercarriage too far forward, ( Just his opinion) what would happen if i mounted undercarriage on the other mount? Quote Link to comment Share on other sites More sharing options...

Rob Fairweather 1 Posted May 25, 2017 Share Posted May 25, 2017 As a returnee to this hobby, I looked upon the plethora of ready made models as a real quick way to get flying for lots of people, myself included. I bought a Riot,(normal size) but ended up with the Devil version. Not overly impressed at all. It would seem that just about all of these Chinese/Vietnamese/wherever ARTF have their own problems. I will not buy another. As long as we keep spending money on them, they surely will not get any better. Yes I have emailed the shop I bought it from, and Century. No, I did not get satisfaction.

David Soper Posted May 25, 2017 Author Share Posted May 25, 2017 I phoned Century and they sent a new servo 1st class post... i offered to pay because i dont expect something for nothing ... what i do expect is some comfort the model will not fall out of the sky Quote Link to comment Share on other sites More sharing options...
David Soper Posted May 25, 2017 Author Share Posted May 25, 2017 Had enough of the XL just bought the Sukhoi SU 29 hope it brings me more luck and enjoyment ! Quote Link to comment Share on other sites More sharing options...
David Soper Posted July 6, 2017 Author Share Posted July 6, 2017 am enjoying flying my Sukhoi... but want to alter the default gain in the 636. RX default gain is set at 17% but there is hardly any movement from flight surfaces ... maybe thats enough but can i alter it. Ive heard E Flight 636 is not programmable. Also the AS3X app will not run on my phone (galaxy alpha) i have tried everything ... but app just said stopped working ... I can use PC as app seems ok Quote Link to comment Share on other sites More sharing options...
Kim Taylor Posted July 6, 2017 Share Posted July 6, 2017 I know that it can be changed using the connecting cable and pc app, but I don't know how. Plenty of discussion regarding changing the settings in the 'Safe in another plane' thread on RC Groups, maybe look there? Kim p.s. I know the 636 isn't 'Safe' by default, but the new Safe Select models use a re-programmed 636, so it's the same thing. Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted July 6, 2017 Share Posted July 6, 2017 David, you really do need very slight surface movements, as any more and the model will continually shake in a slight breeze, as it makes adjustments A correctly set up stabiliser is barely susceptible movements on the ground Quote Link to comment Share on other sites More sharing options...
David Soper Posted July 6, 2017 Author Share Posted July 6, 2017 ok ty for that info Denis i guess they set default gain at 17% as it the optimum ... us newbies should not meddle i think lol Quote Link to comment Share on other sites More sharing options...
David Soper Posted July 6, 2017 Author Share Posted July 6, 2017 i need to calm the model down a bit as it too feisty for me .. if i lower rates will it affect the gain? Quote Link to comment Share on other sites More sharing options...

Gain and rates are separate things, the gain is how fast the gyro reacts to control or external disturbance. By setting rates you are reducing your instructions to the Gyro, so if at full rate full control was telling the gyro to rotate at 100 deg/second if you put 50% rates in then full control will now be 50 deg/second, i.e. reducing the instruction to the gyro for a given stick movement. I have a Spektrum Flybarless controller in a heli and used rates and some expo to tame the model down a bit for me. Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted July 7, 2017 Share Posted July 7, 2017 The gain, which is set quite low initially, until you test fly it Is unaffected by the throws you choose to have on your surfaces. As you suggest, have the recommended throws set as normal Then have as a starting point 60% on your rate switch, which should calm things down And don't forget to throttle back while you become familiar with the model. Pretty soon, you will be turning things back up Edited By Denis Watkins on 07/07/2017 16:13:27 Quote Link to comment Share on other sites More sharing options...
David Soper Posted July 7, 2017 Author Share Posted July 7, 2017 i have low rate at 30% and still perfectly flyable .. its became a low wing trainer which is what i need Quote Link to comment Share on other sites More sharing options...
David Soper Posted July 17, 2017 Author Share Posted July 17, 2017 An experienced aerobatic flyer flew my Sukhoi SU 29 MM and he felt C of G was not quite right.. he said battery need to go forward 20mm but it is fixed at the forward foam bulk head... anyone else had this issue?
