I dont think it is possible to damage it with a lean bottom setting. As you say, it won't idle or pick up properly if too lean. Too lean a top end MUST be avoided and the needle should be set so the speed is 300rpm slower than highest speed by richening the mixture, so they say Sent from my MB525 using Tapatalk 2

For modern Saitos they recommend 10-30%. I use 10% and mine run fine Sent from my MB525 using Tapatalk 2

Graham, It is fine to post pictures, we would like to see some

What idle speed are you trying to obtain? I find my 82a won't idle slowly, min about 2200rpm. Whereas my asp80 will idle happily at 1800rpm. Have you got a tachometer? Sent from my MB525 using Tapatalk 2

Hi Graham, I am glad you have nearly completed yours. How about some pictures? Mine has about 20mm up/down deflection on the elevators and about 12mm up/down on the ailerons with no differential. I did try some differential but I found that zero differential was about right. I ended up with about 12oz lead in the nose. This moved the CoG about 10mm back from that on the plan which gave a much "lighter" feel to the plane but I would suggest sticking with the plan position to start with before experimenting as it becomes very sensitive if CoG is too far back. I have a Laser 75 engi

As Peter says, the Dennis Bryant one is a Mk22 and too small for petrol. If size is no object and you enjoy building then the DB Sport one is the one I personally would go for. The Mick Reeves 1/4 scale is big and needs 60-100cc petrol, probably too big. His 1/6 scale one is probably a bit too small for petrol. The next choice would be the Brian Taylor 83" span. The Kyosho artf 90 size is a good plane and flies well but probably a bit small for petrol.

if you have a spare 60 minutes to watch it. If not, take some time and skip through it, there are some great shots of some historic planes and some formation fly pasts at the end.

I found this shaft which fits the standard Wot4 Foam-E motor. They are cheap but seem to be at least as good as the original. Only problem, it was in Hong Kong and postage costs more than the shaft but I needed some other stuff as well so that wasnt a problem. I managed to replace my shaft which broke on landing. It took some hammering to extract the old one, after I had undone the grub screw at one end and pulled off the main body of the motor. A press of some sort would have been better but I dont have one. The new one went in with a bit of persuasion (hammer again), first making su

Possibly the most useful YouTube Video EVER!!

really useful information -
I have in the past just sliced a new hinge slot in the same position as the old cyano hinge, just run a blade down the side of it without removing the old hinge as long as it is securely fixed. These hinges are so thin anyway that doing this doesn't displace the control surface too much. If you pull them out it can sometimes leave a big hole in the wood.

Arun, I covered my Maggie with the tail attached. Just cover each surface separately starting at the bottom and overlap the covering in the corners. Do the fin last so that the covering overlaps the tailplane covering. Sent from my MB525 using Tapatalk 2

It does look great, good luck with the maiden Sent from my MB525 using Tapatalk 2

Excellent, thanks Shane. I look forward to the new version with fresh images with great anticipation.

Hi Shane, I still think it would be great to have this site available if it could be made better. A couple of points I noted and I hope they are useful. If you crash into The Oak Tree, the bits of plane fall onto the end of the runway; a distance issue here. Also, if you fly into the fir tree at the other end, the plane flies right through it. Not sure if these can be corrected but thanks anyway for what you have done so far.

Would a decent compact digital camera capable of taking 180 degree panorama shots be good enough or does it require specialized gear?
-
Shane, It would be great if you could complete the Fickleshole field. I am sure it would inspire some trainees to practice on the simulator some more and would also advertise the club. I too was an (Electrical) engineer until I moved into IT about 38 years ago, been developing and supporting CAD systems and databases mostly.

I like the side mounting of the Saito, should save some grief over broken rocker covers. Ask me how I know!

Won't be as powerful as the real thing though Sent from my MB525 using Tapatalk 2

Steve, Have you got wheels? I have a wire undercarriage which would probably do. It has been used on another plane so it is not new and it has no wheels.

Excellent! Wouldnt it be great to have the time to do that. And the facilities. Skills. Money. Somewhere to fly it. Sent from my MB525 using Tapatalk 2

Excellent, thanks Mike

Those are some good tips and links Sent from my MB525 using Tapatalk 2
