    Just taken delivery of some new servos from that wonderful shop with superb service in Frodsham. I have successfully used these little marvels of electronic and mechanical engineering since the 70s, making best efforts to employ the correct linkage geometry for the task i.e. servo arm and control horn positions. One thing which I cannot find definitive reference to, (even on the manufacturers web sites), are the numbers on the servo arms and their meaning. 1 to 4 on the 'cross' arm types and numbers such as '18', '15' and '12' on the HiTec example I'm studying now. Is there a source of information? (Strangely they don't include it in the servo packaging). Are the numbers off-set degrees from 90 and torque for the respective servo arm hole? Obviously from my use down the years, not knowing this info hasn't prevented use but it would be 'nice-to-know'.

    Remember this 'RM' cover give-away 'Building Buddy' from a few years (and some!) ago? I've found it useful to check the odd item at a show or just own stock whilst doing a build. Wonder if it's economic for magazines to do such these days(?)

    Why not simply Download the 'Outerzone/Aerofred' etc. plan onto a PC stick. Take it to your local 'Prontoprint' shop, (other print shops are available!), and for usually a very modest fee, they will print the plan in original or any size you wish. As many copies as you like and no joins as it's all on one clean sheet.

    Martin unless my experience in the Royal Air Force was an illusion, Hunters fairly regularly went supersonic, at least the ones stationed at RAF Brawdy did circa 1974. True they had to climb then go into a fairly steep dive to achieve it. Perhaps any former 'Hunter' jockeys amongst us will comment and confirm(?) Post Script: Online descriptions detail that the Rolls Royce Sapphire with afterburner enabled the Hunter to achieve Mach 1.67 in level flight. Edited By Capt Kremen on 25/01/2020 14:45:35

    Although often at a 'Premium Price', would one of the major supermarkets be a source of Eneloop/Panasonic/GP type cells? Their reputation(s) would be on the line if they were caught knowingly selling dud/fake products.

    Just back from Ali Pally. Mmm ... 'A' for effort to all the modellers and their various works of art/modelling but the show pales in comparison with German model shows. Size, organisation, variety, stands. Still Andy Symonds was doing sterling work on the BMFA stand accompanied by Martin Dilly. Also the R/C simulator was doing good trade albeit with grey and shiny headed folk, no youngsters alas. As stated, very little for aeromodellers there. LMA displayed a few of their members large models and the BMFA stand was adorned with various models from all disciplines i.e. Free flight and R/C. Average age of attendees, conservatively 60+. A couple of pics:

    Adding to Ian Rs comment about stiff control run wire pushrod. I 'polished' mine with Duraglit metal polish. During radio servo installations on all my models, I use an amp meter inline with the servo and measure the operational, (albeit static) current drawn. Amazing the results before and after treating or even replacing supplied ARTF control runs! Also replace those rather 'delicate' cheap plastic kit clevis with quality ball clevis. No back lash or lost movement in the linkages then. Why have a good radio Tx and servos, (not the kit ones obviously!), and loose precision control input movements(?)

    Keith, Fair enough, and I don't blame you given the 'qualities' (sic) you have experienced of the 'Riot'! I have a family of Chris Foss designs (all-electric powered) - 'WOT4', 'WOT4 PRO', 'Acrowot', 'UNO-Wot', and 'WOT Trainer'. Surprised as I am to admit, but I get as much 'fun' out of my 'Riot' as the 'Wotties' ('WOT Trainer' excepted which is fabulous all-rounder IMHO). The 'WOT' range of ARTFs (foam or wood/ply), I found had as many deficiencies and shortcomings, poor materials, fittings etc. and thought typical par for the course for ANY ARTFs, i/c or electric.

    Here are some pics of my 'mod' to allow larger capacity 3S (and 4S at a push) LiPo into the 'Riot'. Also the 'velcro' style wrap over strap securely holds that awful brittle plastic battery hatch closed. The strap passes through slots on the top side of the fuselage such that the ply inner frame, (trimmed down to let the LiPo in!), stops the strap see-saw cutting its way through the foam fuselage sides.

    Just servicing my very much tinkered with 'Riot' before another seasons flying. (Now eight (8) years old according to my flight log book!) My previous posts and review have detailed the numerous changes and substitutions of equipment I made to this airframe. As this topic is about upgrades and motor/battery performance here are my notes: Currently using a, (now discontinued), 4-Max PPO-3530-1100Kv motor on 3S and a 10x5 prop. The model is far from 'supersonic' but it can easily perform all sport manoeuvres i.e. Loops, Bunts, Rolls, Spins, Stall Turn and combinations of these. I did try a 4S pack with a(nother) motor but personally found the extra omph wasn't warranted and if anything wasteful as the airframe reached its VNE i.e. max speed and unlikely to go faster before flutter and self-destruct took hold! The comment from 'MaxThrust' about the change of prop ... Mmmm well they may say that, but any supplier with a job lot of props as 12x6 were perhaps not available, (or any substitute items), would likely do that! Meanwhile, my 'Riot' has had its 'Major' and is serviceable for another seasons 'hack' flying in all winds 'n weather, for training, fun sport aeroes, touch 'n go, refresher training, an all-rounder providing IMHO, parts are changed and modified.
