john stones 1 - Moderator Posted March 15, 2017 Author Share Posted March 15, 2017 Slight curve on it's back, yours the same or do i sand it out ? John Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted March 15, 2017 Share Posted March 15, 2017 Can't help you here I'm afraid, John. But still following with great interest. Cheers Chris Quote Link to comment Share on other sites More sharing options...
Martin Dance 1 Posted March 15, 2017 Share Posted March 15, 2017 Hi John, mine is the same, a very slight curve upwards around F6F7, I cut my formers from the plan. Two explanations, 1. I'm lousy at cutting formers accurately, probably true or 2. Lindsay did it deliberately to avoid the possible 'starved horse' appearance if it was dead straight. However not enough to worry about.

john stones 1 - Moderator Posted March 15, 2017 Author Share Posted March 15, 2017 Cheers Chris Yep i cut my own as well Martin, Lindsay's fault/idea sounds good to me though John Quote Link to comment Share on other sites More sharing options...

Lucas Hofman Posted March 16, 2017 Share Posted March 16, 2017 Same on mine. It would change the character if is would be a straight line. The sides curve in too. Lucas Quote Link to comment Share on other sites More sharing options...

john stones 1 - Moderator Posted March 17, 2017 Author Share Posted March 17, 2017 Yes Pete Lecky, This one, 60amp esc, 4cell lipo. John Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted March 17, 2017 Share Posted March 17, 2017 Good choice. I will use its smaller brother. The 3542 800kv. That runns at 6000'rpm with a 4cell lipo and an11x7 prop. Just under 500W and is very quiet. Have used that on the Ballerina and a 60' Avistar. It combines very well with a turnigy AE regulator. I use the AE-45. Runs cool wil gentle acroflying Lucas Quote Link to comment Share on other sites More sharing options...
Low pass Pete Posted March 20, 2017 Share Posted March 20, 2017 Hi John Have you been able to get any idea what the dihedral on the lower wing is. I cannot find reference to it at all on the plan. Cheers Peter Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted March 20, 2017 Author Share Posted March 20, 2017 It shows dihedral brace on the lower wing plan Pete, you could plot it off that or make a template, not read Lindsays blog but i think he fitted to one panel and built on to it ? John Quote Link to comment Share on other sites More sharing options...
Martin Dance 1 Posted March 20, 2017 Share Posted March 20, 2017 I extended the bottom edge of the dihedral brace out to the span length and found the dihedral was about 1/2" in total. I think more aesthetic than adding anything to the planes stability. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted March 29, 2017 Author Share Posted March 29, 2017 Apologies for the absence i've not been in the mood. top wing joined, some balsa added on the rear spar for a 1/16 ply brace. John Quote Link to comment Share on other sites More sharing options...

Chris North 3 Posted March 30, 2017 Share Posted March 30, 2017 Looking good and very impressed with the build quality. I do plan on building the Skywriter but we could be moving house in the next couple of months so there is a ban on any new building for now. I think I would have to either get the laser kit or cut out all of the formers and parts before I started building. Having to stop to do fiddly formers and stinger slots is a real motivation killer!

Tim Ballinger Posted March 30, 2017 Share Posted March 30, 2017 John, Looks like you have a camera in the ceiling 🤔 ... and my slow down is a 3 week break, after which I hope to start covering. Tim Quote Link to comment Share on other sites More sharing options...
Martin Dance 1 Posted March 30, 2017 Share Posted March 30, 2017 Nice building John, love the weights on the wing! Is the wooden bowl made from lignum vitae?. My build is substantially complete just all those it'll only take a minute jobs. I've fitted the U/C mount so I thought I'll fit the lower wing bolt assembly. Ah ha the fuselage side view shows the bolt going through the wing slightly ahead of the wing bolt reinforcing block which is attached to the sub trailing edge spar. Turning to the lower wing drawing the bolt hole is quite clearly and firmly through the trailing edge. My thought is to go through the TE, it is reinforced with ply so should be adequately strong. The position shown on the fuselage will work equally but the reinforcing block in the wing isn't that big and clearly not a good idea to drill through the TE sub spar. Fellow MB ers thoughts?

Lucas Hofman Posted March 30, 2017 Share Posted March 30, 2017 Martin, I noticed that discrepancy too. The trailing edge is only glued to the rest of the wing with a not too big glue line at the front so the location on the fuselage drawing must be the correct one. I place the wing bolts (2 to avoid the join between the wings) between the aft spar and the inner trailing edge. I put 2x2cm squares of 1.5mm ply inside of the lower sheeting and filled up the space to the upper sheeting with soft balsa. This way the bolts will not crush the wing. If you have all sheeting in place on the lower wing I would drill the hole through the TE very close to the spar and use an external ply plate that extends from the aft of the TE to the front of the reinforcment block as draw on the plan. That should keep things in place I would think. Lucas Quote Link to comment Share on other sites More sharing options...
Martin Dance 1 Posted March 30, 2017 Share Posted March 30, 2017 Lucas, that was my conclusion too. The ply reinforcement in that area will strengthen the TE/TE sub spar joint anyway and a small piece of ply on the upper surface of the wing will provide some extra support. I was going to use two wing bolts as well, either M4 or M5 nylon bolts. Although I did have one model where the wing bolts were 4BA simply threaded into a hardwood block and it never failed, much to my surprise.

john stones 1 - Moderator Posted March 30, 2017 Author Share Posted March 30, 2017 Thanks for the comments fellas Held my camera high so i didn't get my shadow Tim, It's a piece of Ash Martin, mate of mine did woodturning and i used to give him any Ash we cut down at work.

Tim Ballinger Posted March 30, 2017 Share Posted March 30, 2017 Martin, I had the same wing bolt conundrum. I used 2 X 5mm bolts through the TE and used a large square of ply to bridge the the te/spar/balsa fill region. Pretty much as you and Lucas discussed. Picture of it in my blog somewhere.
