    IC Trainer

    in Buy & Sell

    Posted

     

    Hi Karl,

     

    I would consider switching your order for a Boomerang II. As Martin says they are essentially the same airframe except for the wing section. You will probably find that the semi-symmetrical wing section on the Boomerang gives better performance in wind (this is the UK) as it is less likely to balloon as you turn into the wind and of course a better level of lift if the craft is inverted. You may think you won't be using it for inverted flight, but chances are it is going into this attitude as you increase in skill, or during training. In the latter case, your instructor will have a better chance of recovering the airframe from a low-level situation if they can call on inverted-lift.

     

    Totally agree with Martin on the nose-leg. Whilst learning 3-point landings is a great skill for all pilots, unless you are learning off of a smooth runway (and even if you are) you are going to spend a lot of time replacing broken props and nose-legs. This gets expensive, and the latter usually stops play for the day which isn't what you want when training. Pretty sure the Boomerang II comes with a tailwheel conversion kit.

     

    Ultimately you won't go wrong with an Arising Star or a Boomerang II, but I don't think the Boomerang II is any harder to learn on, yet has some advantages over the Arising Star. The Boomerang may serve you longer into your flying career due to its inverted performance (e.g. I still enjoy a *very* low inverted pass with a trainer - it teaches excellent inverted rudder and aileron control due to the dihedral working against you).

     

    Cheers

    Have a go at IMAC 2016?

    in General chitchat

    Posted

     

    As some of you may know, I tend to spend most of my airtime practicing for/flying in IMAC aerobatic competition and am currently the Secretary for the organisation.

     

    We have invested a lot of effort this coming season in providing a new pilots training day and also a heavily upgraded website containing all the information you might need to have a go at your local field.

     

    I know that IMAC typically uses larger models than are allowed at Fickleshole, but there is no reason why you can't use a smaller model when starting out.

     

    Do take a look at the website and consider giving it a crack in 2016!

    Laser Jigging

    in Scratch

    Posted

     

    I thought this might be of interest to some; in my current build I was trying to find a more accurate way of jigging and lining up on the fuselage than just eyeballing vertical lines drawn on formers. I found that my cross-line laser level fixed to a rafter in my workshop and pointed directly at my SLEC building jig is a very nice solution.

    I have an OS 81FSa I might part with. Same case size as the OS70 Surpass so might be of interest. It's brand new/boxed/un-run so you can be sure it works :)

    Throttle arming switch on Futaba 8FG

    in Radio

    Posted

     

    Martin -

     

    Surprised at this as I've used the throttle curve on the 8FG as a kill many times, however... try using a pair of mixes as below. I'm sure it goes without saying, but test their effect using the 'servo monitor' function rather than chop yourself up with a spinning prop ;)

     

    Mix 1:

    thr -> thr

    Offset: -100

    Rate A: -100

    Rate B: 0

     

    Mix 2:

    thr -> thr

    Offset: 0

    Rate A: 0

    Rate B: -100

    Cougar 2000 CoG

    in ARTF

    Posted

     

    Any suggestions welcomed!

     

    On the belief this model has flown safely before, I'd fly it and see how you like it before going in for any mods. Obviously with a rear-ward CoG elevator sensitivity will be increased, you can counter that in the short term with plenty of expo.

    Phoenix 5.0v

    in Simulators

    Posted

    It does lack a bit of credibility releasing like this. I rather think Phoenix has fallen badly behind Realflight and Aerofly these days. Having flown them all in their latest incarnations and compared them closely against real characteristics the former has fallen into the ashes rather than risen from it!

    OpenTx - and Taranis firmware Update

    in Radio

    Posted

    The lead developer, Bertrand Songis, stated that this is the most stable version of OpenTX they have ever created.

     

    Microsoft say that after every release of Windows for their software. Doesn't mean a thing as "most stable" is a relative term and does not imply "actually stable".

    Dreamflight Libelle

    in General chitchat

    Posted

    Flew my Libelle today for the first time at Chobham & District MFC and loved it! Had between 40-50 "flights" with it during which I made some improvements to the launch technique thanks to helpful critique from Martin who was flying at the Chobham site as a guest.

     

    Had a couple of fights where the model picked up some nice lift which is very satisfying. I was expecting to enjoy gliding, but I think I might be hooked :) Made use of four flight conditions; launch - cruise - thermal and land which have varying degrees of reflex/flaps and elevator compensation.

     

    All in, good fun. Airframe needed a dab of cyano on the vertical stab where the epoxy I initially used released. Balance is at 5mm behind spar which seems fine to me for now. Highly recommend you guys get DLG-ing!
