Hi, thanks for the feedback, it's a great design. I don't remember the exact C of G but I set it up as per the plan and it flew just fine. During the build I focused on getting all the RC as far forwards as possible and keeping the tail light. This meant I didn't need to add any lead to get a good balance.
Hi, thank you very much. Yes still flying but not that much this year. Hope to have a go tomorrow, might be another video if I get some good footage. 5-6 knots forecast.
Hi Mic, I did a few mods. Made it with a removable tail. This saves a lot of space when storing it. Other than that I put some very small diagonals down the fuse. It twisted a lot when first built. I knew the covering would stop almost all the twisting but I wanted to be sure. Like I say very small diagonals because this adds weight where it is very easily felt and needs to be balanced with more lead in the nose. If you look very carefully at the film you will see vertical grain on the keel as well under the cockpit and half way aft. This was to try and prevent the grain of the keel cracking if there was a heavy landing. Repairing a model that has clear film on it will just make a mess of the model, so I have tried to build in a bit more strength at the same time trying not to increase the weight.Has worked well so far. Lovely model to fly, I can recommend it if you are considering it. Cheers, Hugh
Well it is quite a wide tailplane so I did this for the ease of storage through the winter. For the summer I leave it rigged. Less prone to damage if you have a rougher than planned landing as well but luckily that has not happened yet.
Hi, there is one on eBay right now. www.ebay.co.uk/itm/Vintage-Berkeleys-93-Super-Sinbad-Glider-R-C-Laser-Cut-Short-Kit/133237846820?hash=item1f05983324:g:GcAAAOSwQwFcCt0J good luck
Hi, I found mine on eBay, there was a guy in the USA who had made a few kits and was selling them off. it was only a partial kit but the quality was good. Good luck if you decide to make one, its a great model.
Hi, getting the nose covered was tricky. I used solarfilm and cut it as small as possible with several pieces. Lots of heat and worked it down, it was not done in 5 minuets. I had no pattern for the covering i just cut it to hide the RC in the nose. Good luck.
To hinge the tail plane i use standard model hinges. I aligned and installed the elevator to the tailplane to confirm full and free movement. Once confirmed i removed the metal hinge pins from each hinge. Those were replaced with one long carbon pin 1mm . The carbon pin is about the same length as the span of the tailplane. It is just friction keeping it in place and with many hours of flying with the model it has proved to work well. I got the carbon rod on ebay.
I wonder how many times I’d put it back together with the horizontal stab first? I’d bound to be determined to throw the model on the ground and stomp on it!! Really pretty model though. Love your flight videos!!! Tony
I can't wait to get started on mine. I was inspired by the same John Woodfield video you saw on RU-vid. I also bought the 93" short kit and I have an original Sig 62" Super Sinbad free flight glider I'm converting to RC. such a cool looking glider. I'll have to do the removable tail like you did. Wish I could see the way you did yours better. You did a GREAT job!!!
