Bruce Collinson Posted January 27, 2019 Share Posted January 27, 2019 Gone quiet again. Gary, did you ever sort the wing warp out? Given up with the DLE, the new silencer was costing about 800 rpm. Passed it onto a club mate and a Saito 125 is waiting to go in. You fitted yours sideways, didn’t you, with silencer exiting below? Any other issues since the latter postings?

Gary Manuel Posted January 27, 2019 Author Share Posted January 27, 2019 Hi Bruce. The only problem I have with the model is the warped wing. It's exactly where I left it after my last post. I'll get round to sorting it when mojo / health / weather improve. There were no issues with the side mounted Saito. Quote Link to comment Share on other sites More sharing options...
Paul Marsh Posted January 27, 2019 Share Posted January 27, 2019 I'm just building it now. Making it a JCB Scheme. Just ordered a 30cc petrol engine as decided to go the petrol route. I have the other colour scheme with a CRRC 26cc and that goes well and has had many flights. Quote Link to comment Share on other sites More sharing options...
Bruce Collinson Posted May 31, 2019 Share Posted May 31, 2019 I have news on the front wing bolt issue. If you recall, Gary M converted his to dowels and I got my wrists slapped by my elders and betters for copying. It left a small gap at the LE root. We tried every permutation of tools to tighten the bolts, generally involving curtain hooks and holes on thumb head bolts. Without slim, strong hands it's very hard to tighten the bolts manually. Grazing Ian Shaw/Modelfixings for some replacement wing bolts for an Acrowot, which are 1/4 20 UNC and not M6, at least on my nearly finished one, I saw a Proxxon socket and screwdriver set with a slim ratchet handle, 3 lengths of extension shaft, and a neat UJ, on offer. It winked at me. It's excellent, all Proxxon kit seems to be and Ian reckons the 10mm socket in the set is a good enough fit on a 1/4 20 hex head nylon bolt. The equivalent socket head bolt requires a 3/16" hex key which isn't a stock item and Ian's looking for a supply which doesn't involve buying a whole boxful, but again the Torx 25 in the Proxxon kit is a nearly fit. I'm waiting for the bolts with hex heads but had a play with the socket heads last night and am convinced it's a viable and very elegant solution. I'm aware that this space congestion isn't unique to Seagull Yaks and I commend the potential solution to awkward wing bolts. The Proxxon set is going to get a huge amount of use and a spare in the flight box is a distinct requirement! BTC Quote Link to comment Share on other sites More sharing options...
Bruce Collinson Posted July 1, 2019 Share Posted July 1, 2019 Flew Sat for the first time with its Saito 125, no cowl, about 6 oz of lead for a 140mm c of g. Ample power, twitchy on elevator until we dialled it right down and it landed with appreciable up elevator. As my superiors felt the c of g was good, I suspect wing incidence which will be another pain in the rear. At least the new wing bolt tightening method was much easier, though one of the fronts worked loose in flight so they'll have to be nipped up in future. Cowl fettling continues.

Gary Manuel Posted July 1, 2019 Author Share Posted July 1, 2019 Well done Bruce. I really must get my backside into gear and get my warped wings sorted. Quote Link to comment Share on other sites More sharing options...
Bruce Collinson Posted July 2, 2019 Share Posted July 2, 2019 Gary, Worth a try on BMFA Classifieds to find a new wing set? Cowl; am I getting tiny g/f splinters every time I touch it?! What was the stuff you used for the ducting/blanking in yours? I was thinking 1/8" ply then remembered you'd used foam board which I guess would be easier to shape. Also remembered that there was discussion over mine re the incidence, which might have been nearly right as 5mm of up el suggests to me it needs some positive incidence added. You can see why Acrowots are so popular, can't you? BTC Quote Link to comment Share on other sites More sharing options...
Gary Manuel Posted July 2, 2019 Author Share Posted July 2, 2019 Bruce. Engine baffling material is Darice 6mm Craft Foam. It's solid foam, fairly dense but easily cut and glued. Not easy to get hold of the original Darice brand at a decent price in the UK though. There are other brands but I'm not sure how good they are e.g. Staples stuff was card coated foam - not really the same thing. The 2 links are click-able.

If you go down this road, it might be useful to know that although almost identical in planform and size, the black and yellow version has different section wings to the yellow and blue one.

Gary Manuel Posted July 2, 2019 Author Share Posted July 2, 2019 Thanks Martin. I'll bear that in mind. Edited By Gary Manuel on 02/07/2019 18:25:38 Quote Link to comment Share on other sites More sharing options...
Bruce Collinson Posted July 2, 2019 Share Posted July 2, 2019 Thanks Gary. Ordered some. What was the best glue? when it lands I’ll check out UK equivalents and report back. BTC Quote Link to comment Share on other sites More sharing options...
Gary Manuel Posted July 2, 2019 Author Share Posted July 2, 2019 Can't remember whether I used Cyno or UHU Por. Either would work. Quote Link to comment Share on other sites More sharing options...
