Rich too Posted November 18, 2017 Share Posted November 18, 2017 At last I can get started on this - my birthday present last summer! I am a slow builder, and hope to have it ready for next summer. Quote Link to comment Share on other sites More sharing options...

Adrian Smith 1 Posted November 18, 2017 Share Posted November 18, 2017 I just love the SBach Rich, always have always will! Look forward to following the thread with interest. Do you know what engine is going in it & servo Specs? Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted November 18, 2017 Share Posted November 18, 2017 Very nice Rich, what’s going up front. Quote Link to comment Share on other sites More sharing options...
Rich too Posted November 18, 2017 Author Share Posted November 18, 2017 First job is to mount the motor, and then position the firewall correctly. I was not very impressed with the fit of the firewall, it took quite a bit of adjustment to get it to fit. Quote Link to comment Share on other sites More sharing options...
Rich too Posted November 18, 2017 Author Share Posted November 18, 2017 Thanks gents - you may have guessed now - DLE 111. Yeah, I have to agree, I think the Sbach is a handsome model. Quote Link to comment Share on other sites More sharing options...
Rich too Posted November 18, 2017 Author Share Posted November 18, 2017 For servos, probably 8 x Hitec HS5585MH (or 5765) for the control surfaces. And I will probably use an XPS 24 control box, which takes care of my lack of channels and servo matching.

Rich too Posted November 18, 2017 Author Share Posted November 18, 2017 I think servos are over specced a lot these days. Pilot specify a min 180 oz in which equates to only 13kg. And I am no 3D flyer!! I think on balance I will go for the 5765's which are slightly higher spec, and comfortably over what Pilot rec.

Adrian Smith 1 Posted November 18, 2017 Share Posted November 18, 2017 I tend to agree with you there, Rich. I accept that for 3D some exceptional gear is required, but standard aeros with a bit of freestyle the spec recipe is a bit more modest based on my experience.

Paul Marsh Posted November 18, 2017 Share Posted November 18, 2017 I have a 50cc one and is my favourite model. Maybe next year I will get a 100cc one, with a DLE 120. The current one has a 55cc flat twin and goes well. Quote Link to comment Share on other sites More sharing options...

Rich too Posted November 19, 2017 Author Share Posted November 19, 2017 I carried on with the motor install and firewall reinforcement. Manual suggest a spinner to cowl gap of 1/4 to 1/2 I decided on 6mm. I am pretty happy with the fit. Quote Link to comment Share on other sites More sharing options...

Ultymate Posted November 21, 2017 Share Posted November 21, 2017 A word of warning, about a week ago my DLE 120 sheared the four 5mm counter sunk set screws that hold the engine to the metal plate that then mounts to the said plate to the bulkhead via the standoffs with 6mm bolts. I was doing some 3D tumbling at the time which does I know induce fairly heavy gyroscopic loads, any way as I flew out of the tumble I was aware of a distinct change of note from the model and found that the throttle was jamned at nearly full throttle thanks to the engine moving forward in the cowl so had to promptly kill the ignition and land dead stick. I overshot the strip and took out my landing gear but repairs will not be too difficult. The said countersunk bolts may look like they are high tensile but they are not as I drilled the remains of one quite easily, also the allen key socket is very small in them so making it difficult to give them a little more tightness and they could be longer as the holes in the rear of the crankcase are considerably deeper than the supplied bolts I don't think I can go to bigger diameter bolts but will definitely be using high tensile bolts longer in length and not of the countersunk variety P.S. enjoying your build thread Edited By Ultymate on 21/11/2017 08:47:18 Quote Link to comment Share on other sites More sharing options...
Martyn K Posted November 21, 2017 Share Posted November 21, 2017 A bit intrigued. On the Firewall to Firewall box junction, does the balsa triangle strip actually add any noticeable strength or other structural benefit or is it there for aesthetic reasons? I would have thought that aluminium angle strip and multiple bolts would be where the strength lies. Anyway.. Watching this. I love to see how these things go together Martyn Quote Link to comment Share on other sites More sharing options...

Perhaps they are sacrificial? Thanks for the heads up on it. Quote Link to comment Share on other sites More sharing options...

I love to see how these things go together Martyn I agree Martyn, the triangle is supplied and the manual says fit it! There is also more of it on the inside. I usually pin the firewall, I don't think I'll bother on this one! Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted November 21, 2017 Share Posted November 21, 2017 Looking good Rich. Had the chance of an Sbach recently with twin in it for a really good price, too big for my car though. Quote Link to comment Share on other sites More sharing options...
