cymaz Posted September 24, 2023 Share Posted September 24, 2023 A deal was done a few weeks ago between myself and Mark. I’ve ended up with a 105” Tigermoth ARTF by Maxford USA. I’m modifying a few bits, not many, as the model was in good condition. Just a few things I might be able to improve. The airframe is fitted with an AGM 55cc 2t petrol. The timing has been adjusted and will handstart quite readily. I have been busy added centre strut supports which have really added considerable stiffness to the struts. New Mick Reeves instrument panels have been added and the front one modified to take the switches and ignition light. The next job is to add the reciever, tidy up my servo wires and then I will check over the wings.... 1 Quote Link to comment Share on other sites More sharing options...
cymaz Posted October 2, 2023 Author Share Posted October 2, 2023 Many hours checking through everything. I’ve changed the wing retention from self-tapping screws and plastic tabs to m5 bolts and aluminum strip. I’m more satisfied with this. Just the bottom wings to complete and then it’s on to check the cg. Started the engine up again last Sunday and it ran very well. I’ve added some thick reinforced silicone tube to the exhaust outlets, this has cut down the sharp noise tone quite a bit, we’ll see if it’s enough to pass the field noise limits.... 1 Quote Link to comment Share on other sites More sharing options...

cymaz Posted October 3, 2023 Author Share Posted October 3, 2023 One of the clubs I attend have a 84dB limit, one has 82dB and the third no limit. All but 2 of my petrols pass the 84dB but over the 82dB. I’ll report back 🦻 1 Quote Link to comment Share on other sites More sharing options...

GrumpyGnome Posted October 3, 2023 Share Posted October 3, 2023 Why? We're a small club, in a very rural setting - the farm machinery that surrounds is is noisier...... Quote Link to comment Share on other sites More sharing options...
cymaz Posted October 3, 2023 Author Share Posted October 3, 2023 Just done the cg. The book number is 263mm back from leading edge on top wing. Mine is just slightly nose down on this. I assume the book figure is correct! Quote Link to comment Share on other sites More sharing options...
cymaz Posted October 4, 2023 Author Share Posted October 4, 2023 Rudder and tail wheel ( yes...tail wheel. Some tiggies did have a wheel) all in and working. Batteries all in and good. Saturday is looking the day for the maiden Quote Link to comment Share on other sites More sharing options...
Andy Gates Posted October 4, 2023 Share Posted October 4, 2023 Beautiful machine you have there Cymaz, quite envious but I am in an electric only club so this would need huge batteries so I will let you keep it. Fingers crossed for the maiden..... Quote Link to comment Share on other sites More sharing options...

cymaz Posted October 7, 2023 Author Share Posted October 7, 2023 Some pictures after the landing. Needs a boot full of left trim, 3/4 of what I had! And a lot of down trim. I’ll sort this out manually. However once trimming was done she was so docile and smooth. 55cc is way too much so flying around on 1/4-1/3 throttle was all that was needed. The book CG was spot on. The only thing left is to rework the flying wires and get better bolts for the UC. 4 Quote Link to comment Share on other sites More sharing options...

You will find that if the noise is producing money and better still a profit, the authorities won't complain. Quote Link to comment Share on other sites More sharing options...
cymaz Posted October 8, 2023 Author Share Posted October 8, 2023 I think I’ve found out why it needed so much aileron trimming. There’s wash in on port upper and starboard lower wings. Another little job. The elevator trimming will be neutralised.. Quote Link to comment Share on other sites More sharing options...
bert baker Posted January 11 Share Posted January 11 Having admired your nicely fitting dash boards. I’ve dug out the one I makes from the Mick Reeves dash kits I think there were two options and I think I’ve got the wrong ones It’s to do with the outer profile shape there nice kits but I need to make a call and poss send my old ones to be re made to my profiles Quote Link to comment Share on other sites More sharing options...
cymaz Posted January 11 Author Share Posted January 11 (edited) I know I had to trim mine a little on the bottom corners. It could be the formers don't quite match. Flew it last weekend. Much, much better now that the twist is out of the upper port wing/aileron. Took off straight as an arrow. The baffling works and it went through the noise test easily.
