Ian Southerton 1 Posted April 27, 2015 Share Posted April 27, 2015 Nearly finished. Bit of a porker though! 5Lb 4oz with 4oz of lead up front to bring the cog forward ! Has a 4500mah battery.

Ian Southerton 1 Posted April 27, 2015 Share Posted April 27, 2015 Looks great! I'm tempted to go ic  (been offered a canary 40 trainer cheap) and build another bullet! Quote Link to comment Share on other sites More sharing options...
Ian Southerton 1 Posted April 27, 2015 Share Posted April 27, 2015 Weighed the lipo battery, just over 1lb! So, without a battery and lead, she's 4lb. Quote Link to comment Share on other sites More sharing options...
Richard Wood Posted April 30, 2015 Share Posted April 30, 2015 Couple of nice looking Bullets there - for a 40 year old design it still looks superb. I never tire of looking at 'em! 5lb 4oz is about the same as my last one & it flew well - very smooth & nippy. An ASP40 was a perfect match for my ancient old white Bullet - a 40 is all it needs.

Tempted to go if as it reminds me of my dad taking me to Sutton park in the 70's, I love the smell and miss my old 2 stroke bike! Quote Link to comment Share on other sites More sharing options...

Jack Banner Posted May 2, 2015 Author Share Posted May 2, 2015 Nice to see all these Bullets! I was flying mine again today, so I took a few snaps. It is pretty much my favorite plane at the moment. I hope to get around to building one from scratch one day. This one was bought second hand, recovered and refitted and it fly's a treat.

Ian Southerton 1 Posted May 17, 2015 Share Posted May 17, 2015 Maidened my electric bullet today! Got my mate (Shane Harding) to maiden her, turns out, somehow my expo was set at 100%, glad he flew her first. Reprogrammed the tx and Shane took her up again and said she was perfectly balanced and flew really well! He put the tx strap around my neck and said my turn (I'm an inexperienced flyer) and talked me through a take off, 3 circuits and a near perfect landing, I was really chuffed! I only have one battery at the moment, but will be ordering another. Took my foam wot 4 up and it was terrible in the gusts and side winds. Building acrowot with an os .46ax, can't wait to maiden that one​ Quote Link to comment Share on other sites More sharing options...

Richard Wood Posted May 27, 2015 Share Posted May 27, 2015 Very nice job. The traditional red/white bullet scheme suits the thing well. If you're like me, after making spanking job of a model I get nervous as heck before the maiden. So deep breath & all will be well. Quote Link to comment Share on other sites More sharing options...
Ian Southerton 1 Posted July 5, 2015 Share Posted July 5, 2015 Well, checked the bullet over after the maiden and found the motor had fore and aft play. Turns out the grubscrew had come out and the shaft had moved. I tried to repair it but somehow managed to damage a bearing. So, I bought another motor, tested it in the garden for 5 minutes and found this one had axial play. I ordered new bearings and repaired both motors, but the second motor had the same issue after 5 mins and the first motor just didn't sound right. I emailed the supplier who were of little help and to be honest I've had loads of grief with their esc's too! I then bought a cheap turnigy motor and modded the front of the bullet to suit. I flew it twice today but the ESC kept playing up and the motor was very hot (think it's too small), it also seemed a little under powered. The bullet itself flew like it was on rails (although there was little wind this morning) and I enjoyed flying it. Only issue was it rolled slowly, so I may have to tweak the travel on the servo. Also wish I'd fitted a steerable nose wheel lol! So, do I persevere and buy another motor and ESC or convert it to ic? What motor ESC/battery combo have you used? Ian.

Stevem3akm Posted July 5, 2015 Share Posted July 5, 2015 Go to i/c, you know you want to. The bullet looks superb by the way, one of the best I've seen a picture of. Regards Steve Quote Link to comment Share on other sites More sharing options...
minty morton Posted July 6, 2015 Share Posted July 6, 2015 For what it's worth mine is the white one in hangar9 nut's picture and used the following:- Motor NTM prop drive series 3548 1100kv 640w 70 amp opto esc with 5A opto ubec 10x7 jamara 45amp 650w 4s 3300 pack 20 percent left after 8 mins. Hope this helps. Minty Quote Link to comment Share on other sites More sharing options...
Ian Southerton 1 Posted July 7, 2015 Share Posted July 7, 2015 Steve, it's tempting! I' can fly at my club anytime with an electric, but we're restricted with IC, so will probably leave it electric and perhaps build an IC one in the Winter. Minty, I have the standard turnigy 3548 1100kv motor. Perhaps it's not got enough cooling and I'm using the wrong size prop? I ran a 11x7 APCE on the recommended Overlander setup and a 11x5.5 APCE on the turnigy as the KV was 1100 (overlander was 900). Ian Quote Link to comment Share on other sites More sharing options...
Richard Wood Posted July 7, 2015 Share Posted July 7, 2015 Sorry to read of bother. If the motor & ESC are working near their max ratings they will get hot - especially if there isn't much cooling airflow. You could try removing the spinner to get some breeze over the motor & try to get a draft over the ESC too if not already & see if it improves performance. Often a well over-spec'd ESC doesn't need too much cooling airflow. If it's any help I used a Scorpion 70A ESC with a Scorpion 3026 890kV motor & 10x7 prop on 4S 3700 Lipo. This draws around 50A full whack., a bigger prop would draw too much current. The cowl is left open underneath for access & airflow. Quote Link to comment Share on other sites More sharing options...
