Am happy to supply details of position of cut out on bottom of fuse for anyone who wants to install this type of gear. The wheel is scale diameter and as per full size there is more door area aft of the wheel when gear down.

Hi Jim,
How's that extra item you purchased... the retractable wheel unit? Is it decent? Can/will you craft bay doors too?

I've been waiting about 6 weeks now and fear my wheel unit is lost in shipping

TT…..They forgot to include it with the 808 box, am waiting to see if I got charged for it on my credit card. Hope not!! Question: did you use steel cable for your rudder pull-pull, if so what did you use and your source. I'm thinking stainless steel fishing leader from WallyWorld!! Also what bellcrank did you use? Regarding the retract wheel, I may check-out Mr. Senntinel45's design.

For the pull-pull I used Berklee Fireline with 65lb test. I also widened the exit holes at the back.

Just grab a solid type of fishing line that does not stretch.

Jim- I used the fishing string and did the pull pull system too- as Charles spec'd @ the Quebec Aerotow site. It was easy and wish I had done other ships that way.

In fact, Charles's build on the aerotow site is so nice, I sought of used it as the build manuel. Can't get any better than having pictures and complete descriptions of the final assemblies.

Thanks again Charles!!!

Thanks for the info on the Berkley fishing line, who woulda thunk it. I am really having a tough time "catching-up" after being absent for 25 yrs. So much info on this site and others, Thanks to all. Not sure if Senntinel45 is going to eventually end-up with total retract via servo or not, maybe he can chime in here and tell us. I do like the design he has so far and it looks like he's headed toward full retractable gear. Winter continues to drag on, am totally tired of it!!

Jim am more than happy to post more details of the landing gear, am afraid it is a bit of a 'make it up as u go along'. I know that there are some superb retract units out there, however my intention was to make a very simple and robust system that would be structural and load the paper thin fuse through its formers and a carbon fibre crush tube (also tied to the front vertical former). I've attached a couple of hand sketches. I'm in bed at mo but will post position of cut out for wheel tomorrow night if you want to go down this route. Although I made the retract from a laser cut profile folded, it doesn't need to be that complex. Could be made from 2 flat profiles with cross joiner tubes and bolts and nuts.

Can post a dxf file of the flat pattern of the retract if you can get local access to a friendly fabrication outfit who might be willing to laser and fold it for you. The hinge is just a little mild steel one which I mig welded to the retract (just two spot welds)

As for making it servo operated, I guess the strut could be pushed fore and aft by a servo which would in turn lift the gear, but this would require the end of the strut to travel within the confines of a slotted runner attached to the top of the gear. Given the geometry of the way ive done this I think the servo might be under a bit of pressure, but will have a look at this in solidworks. I myself dont intend to make the retract come up again after comitting to a landing. im going to have the retract released to 'drop' by a small servo wired to the flaps which will release the catch only on full deflection of the flaps. This way I wont forget to lower the gear (and yes the answer is yes I belong to that exclusive club) on the bloody thing.Its just one less thing to think of I guess. After landing I will simply pop the canopy and re engage the lowered gear back up into its up n locked postion. thats the theory anyway. Hope this is of some help..

Hey Charles thanks. Just looked up your build thread its really great. Love that flying site. ive done the tailplane mod and increased (by 13") and tapered my ailerons. I was lucky enough to get a fairly straight fuselage, but like u had a willy wonka wheel . Im a design engineer by trade so couldnt help footering with a retract system that dosent retract LOL. But if its of benifit to some folks then thats all the better. Im interested that your covering was bubbling like that, I recovered completley as was doing the ailerons again.

My FlyFly DG is nearly finished, just got to balance it and double check the throws and mixes. Will post some pics.

The 3m moulded DG 808 is up on the Hobby King website. Available in the UK, USA, Europe and Aussie. No international sales o/a wing span. If FlyFly can ship a 4m glider, why can't HK manage a 3m one?
