Tim Ballinger Posted February 22, 2018 Author Share Posted February 22, 2018 Thanks Ron. Never had a better feeling flying a model, my dream had always been to build a mosquito but right now a pseudo Tigercat ticks all the boxes. New retracts have now done landings which is two more than the first set ! I did look at eflite retracts but without a close up inspection I was not sure I could mate them with the sprung oleo I fancied and key the leg to fore and aft retraction. I will have a closer look next time I am at a show. Tim Quote Link to comment Share on other sites More sharing options...

Tim Ballinger Posted February 22, 2018 Author Share Posted February 22, 2018 Peter , not sure if you ever got your pair of the sprung oleo legs like I used on Grumpy but looking at yesterdays take off/ landing videos in slow time you can really see them absorbing the bumps. Pleased with that selection. Tim Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted February 22, 2018 Share Posted February 22, 2018 Yes Tim I got three in the end, then realised that the Broucek would have been too small. Never mind' they will sit in my drawer for "That will come in useful one day" stuff. Maybe a .15 size R/C model when I am back in mood to design. At the moment I am building my 5th Super 60 with mods as usual. Quote Link to comment Share on other sites More sharing options...

Tim Ballinger Posted February 23, 2018 Author Share Posted February 23, 2018 Thanks Richard it is a dream to fly. How’s your build coming along, not seen any pics for a while. Tim Quote Link to comment Share on other sites More sharing options...
Geoff S Posted February 23, 2018 Share Posted February 23, 2018 I seem to recall your being a bit doubtful about the power you had available but it certainly seemed to fly with authority and showed no lack of power. You need to be very proud of your achievement of building such a great model. It looks really good in the air and on the ground (not always the same thing!)

Tim Ballinger Posted February 23, 2018 Author Share Posted February 23, 2018 Blue sky was a bonus indeed John, I was just expecting gray. Tanks Geoff I am indeed quite chuffed. I did one fast taxi before I flew and knew instantly there would be enough power and so it turned out. A delight to fly ,all credit to Peter.

rgarde Posted February 25, 2018 Share Posted February 25, 2018 Hi Tim, Thanks for your interest. You're right that there is little progress to be seen. It's a shame but unfortunately I can not change much about it. Have been ill for a week, went on vacation and now busy at work and making extra hours. Hopefully I can pick it up again soon With kind regards, Richard Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted April 9, 2018 Author Share Posted April 9, 2018 I was ready to take out GTC for second session of flights yesterday and during checkout found the Rx battery was completely dead. I knew it was almost fully charged when i left it so was a bit miffed. A relatively little used 2000mAh eneloop at only a year old. Shelved the GTC for the day and took the Riot Xl out instead. Checked everything later on and everything ok, except the battery was indeed dead. Started a charging/recharge cycle ( actually only one cycle as I was impatient to see if it would hold charge overnight). Seemed fine. I have a G.T. Power electrical switch in the rx circuit so began to suspect it was drawing current even when switched off. Yes indeed 2mA. Guess what it is 6 weeks since the last flight/charge which just about equals the battery capacity. Says nothing on the instructions about a continuous 2mA drawdown . Think I might just ditch the switch rather than have to remember to disconnect it after each session. Good news is battery is fine and even better news is that i checked before sending the GTC off to an early grave ! Suspect many of you know this feature of electronic switches but it had never crossed my mind; till now. Tim Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted April 9, 2018 Share Posted April 9, 2018 I must admit that I always disconnect batteries from Rx switches after flights / when putting away, not because of fear of drain (that never really crossed my mind!) just something I do. Now I have a good excuse as to why I do it, thanks Tim! Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted April 9, 2018 Share Posted April 9, 2018 You would have detected a completely dead battery before takeoff Tim. I only have receivers/servo's powered from the main battery (and even if you run them down so far that the ESC shuts off the motor you have enough for receiver/servo's for quite a long glide down) so I am not familiar with the problem. However, does one not always goes out to the field with a fully charged battery? Regards, Lucas Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted April 9, 2018 Author Share Posted April 9, 2018 All true Lucas but IF I had just assumed the Rx battery was ok without checking the voltage and I had gone out a couple of weeks earlier to fly, all would have seemed ok, for a while. But yes I always do check, not least because the Downlink telemetry tells me the Rx voltage and indeed the full Lipo voltage . So you are correct a disaster would have been unlikely but none the less a possibility . The GTC only has a separate Rx battery because I needed a bit more weight forward to balance properly and as I had electric retracts, lights and 6 servos it seemed a reasonable alternative to lead!

Tim Ballinger Posted April 15, 2018 Author Share Posted April 15, 2018 Disaster. Feeling really stupid right now. Was having a another really good session with the GTC yesterday when for reasons I can not really understand I Attempted an Immelmann with way too little energy and deep stalled straight into the ground. I was also too low to do anything other than watch. I frequently use either a split S or an Immelmann to reverse direction but that is with models with much more power that the GTC. I knew that and I still did it. Irony is I had just been checking out the stall characteristics and had noted it took a fair bit of height to recover from such a manoeuvre. I knew it and I still did it. Did try higher rates on the ailerons this session which livened up the roll rate despite the inherent high roll inertia of the twin layout. That’s about the best takeaway from yesterday. Tim Quote Link to comment Share on other sites More sharing options...
Levanter Posted April 15, 2018 Share Posted April 15, 2018 Ouch Tim! How unkind was the ground to you? Less unkind than you are being to yourself I hope. A true stoic that can still report on the roll rate which was one of my questions. Levanter Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted April 15, 2018 Share Posted April 15, 2018 Oh no Tim, that’s a bummer. Hope the damage isn’t too bad. If it makes you feel any better, I wrote off my Laser 240 powered P40 a couple of weeks ago, on its maiden flight! Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted April 15, 2018 Author Share Posted April 15, 2018 Ground was really soft, so much so that from nose to F2 was still buried in the earth, trouble was it was not attached to the rest of the fuze. That bit looks repairable. Rest is shall we say rapid deceleration damage. Front wing dowel broke out but took a chunk of Wing le with it. Awkward bit seems to be that a lot of the LE sheeting has come away along the glue line with the LE of one wing where the dowel burst out.. Only got up the steel to start examining things today but all electrics and powertrain & battery's seem fine. suffice to say there is a bit of work to do before she flys again. sorry to hear about the P40 Ron, that probably trumps my tale of woe.

Peter Miller Posted April 15, 2018 Share Posted April 15, 2018 And if it helps, my Sper 60 was totaled when the battery came loose on its second outing. To quote the old expression, The more spectacular the finish, the more spectacular the finish. Quote Link to comment Share on other sites More sharing options...
Tim Ballinger Posted April 15, 2018 Author Share Posted April 15, 2018 Guessing loose in this instance also resulted in Rx disconnection? Tim Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted April 15, 2018 Share Posted April 15, 2018 Oh yes. There it was in a tight left hand turn and stick waggling did nothing, We never found the battery. I had tried a rough field take off with those huge foam wheels which was rather bouncy but didn't get off this time, Quote Link to comment Share on other sites More sharing options...
Rob Ashley Posted April 15, 2018 Share Posted April 15, 2018 Tim, Peter, Sorry to hear about your losses - especially from two great flying models. I hope you can rebuild them both. Best, Rob Quote Link to comment Share on other sites More sharing options...

Tim Very irritating. You have not had that many hours flying time with the modell. The good this is that you know how everything fits together and have the drawing of all the parts.
