    If your engine is useless as is without a prop driver, then less than 8 quid for a prop driver is cheaper than buying a replacement engine. After all, the likelihood of someone having a spare prop driver to donate is low....

    One available on Ebay here assuming it is an OS 40FP part you are after:   **LINK** Edited By Alan Gorham_ on 28/04/2017 13:10:41

    I have bought sets of foam wings from Cloud Models. They are excellent quality and the owner Phillip is very helpful and friendly. Do a search for Cloud Models on the forum and you will find a build of a Cloud DH98 Mosquito kit which will show you their work. I would happily buy from them again and I say that purely as a satisfied customer. No other connection.

    I am fired with enthusiasm to build a "proper" PSS model now. In fact more than one! But I'm the world's slowest builder, so my aim is probably to build over the coming winter ready for next spring. I will try and make the Orme in August and October this year though with something flyable. I really fancy building something big and glider-ish. The Hawk was literally a zero-cost no emotional loss model that I could not get upset about losing if it didn't work. As Mark says, it was my winter hack and has done 7 winter's service powered by an SC .25. Conversion was quick and dirty and I didn't take any pics. I just took out the motor, mount, tank and throttle servo and fished the Rx battery out from the tail. That fitted in the vacant engine bay and I filled the hole for the cylinder head with high density polyurethane foam. The foam was smoothed to shape and I glassed over the outer surface of the foam. I made the node cone in a similar way, using vertical and horizontal ply keels, then filling out with foam and glassing over. A quick blow over with paint and job done.

    Just a quick follow up.... I took the converted Hawk to Llandudno at the weekend. Thanks to Steve Howarth, Mark Kettle and Phil Cooke for your advice, help and encouragement. Without it I'd have been too chicken to chuck it off the edge. I was well out of my comfort zone, but after a couple of moments in bumpy air and sorting out the trim I had an absolute ball trying PSS flying in great lift. What a thrill - why haven't I tried it sooner?! Mr. Howarth especially - you went above and beyond the call of duty spending so much time reassuring me and talking me round when you could have been flying yourself. I'm definitely hooked. Photo evidence: The one with the random holding it again courtesy of Phil Cooke. Others by me. Loved the Fouga Magister in Luftwaffe colours!

    Balance charging IS normal charging when using multi-cell Lipo batteries! I would check the individual cell voltages with the battery off the charger. My guess is that the charger cannot get the cells to balance, so measuring the cell voltages will tell you how far out of balance they are (if they are).

    From the horses' mouth, the 8J and 10J transmitters use S-FHSS rather than FASST, so your receiver looks like it will not work. **LINK** Corona and Orange make low cost FHSS compatible Rx's that I know of...

    Hi Andy I would be delighted to get in formation with your lovely Hawk! I'm greatly encouraged to give this a try now - next stop the big worm's head! Re the colour scheme - I find it hard to see on a typical grey day up here on the North East coast, so flying from a slope close-in and low will be a good help Edited By Alan Gorham_ on 30/03/2017 11:48:02

    Thanks Piers Its hard to quantify "draggyness" without a windtunnel I guess, but having deliberately glided the model down on a couple of occasions with a dead engine, I am encouraged that things might be ok. I think my weight reduction measures, coupled with the fact the draggy prop blades wont be there any more might mean I don't need a gale to stay aloft. I'm really reluctant to take off the dummy air intakes as the model was meant to be a quick and dirty conversion to have something to fly. If I try it and it doesn't go well, I'm quite happy to build something more suitable!
  17. Alan Gorham_
    Steve - good information, thanks for that. The model's wingloading with engine was 24oz/sq. ft, but I have reduced weight by 8 oz by binning all the engine related bits, so I am hopeful. PS - I flew the Phantom I bought from you in October successfully and it's now stripped down for a refurb/repaint!
  18. Alan Gorham_
    Thanks Chris, those are broadly my plans. Already proved I can balance it with a decent sized battery where the engine used to be, but I am not going to use the awful spinner, I'm making a more scale looking nose with landing light as my access to the battery. My main concern is at 25 oz AUW do you think it will fly in light lift or will it need a good blow?
  19. Alan Gorham_
    Hi All I'd really appreciate your opinions! I came along to spectate at the Orme last October and although the lift seemed light I loved the flying and the spectacular site. Having totally failed to build a proper PSS model over the winter, thoughts turned to converting my old Nijhuis "funfighter" style Hawk and chucking it off a cliff with you all in April. As you can see, the model is not very scale in outline and has a big-ish wing. Ignore the random holding it in the picture! I've taken out the .25 2 stroke, tank and throttle servo and reckon my AUW will be close to 25 oz. Bearing in mind the wing section is carved from 9mm balsa sheet (although it seemed a very efficient flyer with a motor up front!) - What are my chances of success? Thanks Alan

    Daren I'll keep an eye on this thread as I'd really love a Tri-pacer kit from you. Got an OS Gemini that will fit in nicely I hope! If you could just get it done in time for Xmas that would be dandy! (only joking...)
  22. Alan Gorham_
    David So the failure was caused by user error. Even if you had been able to prevent the ESC to Rx signal leads from shorting out you would still have fried the ESC and had an in-flight fire. As you admit it was your error in overloading the power system in the first place. Very hard to design that failure mode out...! Interesting stuff.
  23. Alan Gorham_
    David Because your ESC is opto-isolated, there is no electrical connection between the motor battery and the "logic" side of the ESC. That means that the ESC derives it's logic supply via the receiver and down the signal leads, so you will not get away with your proposed solution.   It would be interesting to know exactly what the cause of your original problem was, perhaps a better solution can then be suggested...

    John I'm a very keen model floatplane flyer and a great fan of all things Schneider. I did already know that your great uncle was the first man to exceed 400mph while flying the S6b - what a fantastic family connection to the superb model you are building. Thanks so much for starting this thread!
  25. Alan Gorham_
    John, fantastic model, will enjoy seeing any progress with it. Are you any relation to Wing Commander G H Stainforth who certainly had a close association with the S6b?
