    Simon P. Great to see your Q-Tee pics. I built one from an Airtronics kit way back in the late '70s. DC Merlin with (then) Sanwa mini gear on R/E. Terrific little flyer. I always meant to build the later shoulder wing version with ailerons. Maybe that could be your next project.

    One of the best R/C videos I've ever seen. Outstanding ! Oh that they were all that good.

    Could be a Veco .21 perhaps ? Made by K & B USA. If it is, they were quite highly regarded in their day i.e. 60s and 70s.

    I am well aware that there are ESCs for brushed motors having even built and used quite a few over the years. My question was - Can I use 4 brushless motors thru one 4 in 1 ESC for normal throttle control. That is, rather than using 4 dedicated ESCs.

    I am toying with the idea of building one of two electric 4-engined models I have been collecting data on. They are both fairly small and to save weight, I thought I would have to use 4 small brushed motors thru one ESC. Is it possible to use brushless units with a 4 in 1 ESC for normal throttle control so reducing the AUW even more ?

    Some lovely shots there. Here are some from a holiday in Tasmania March this year. The trains are quite similar.

    My favourite action shot circa 1980. Model is a Pilot ARF ( ABS fuselage ) 36" Ail/Elev., Cox QZ049. Radio is a Sanwa mini 2-channel converted to single RH stick. Flying off a disused bauxite open cast mine site in the Northern Territory, Oz.

    The 40 FSR I have ( circa 1980) has two 3mm x 0.6 tapped holes either side of the exhaust port where the No.743 silencer screws on.

    In the June '17 issue of this mag, in Alex Whittaker's Weekenders column, shows how he binds and solders piano wire.

    'Lo Tony , To try and answer the last question of your OP, the only sloper I can think of was Traplet plan in the now defunct Radio Modeller,. Called the Predator. Can't put a date to it though. I have the plan and could provide you with a copy if it is the one you have in mind.

    Thanks for the follow-up. Great pics. Maybe try moving the CG aft just a tad.

    That's more like it , Ace. Looks a lovely, well-built bit of kit. Is that a .20 or .25 4-stroke up front ? How does it fly ?

    Having now seen the side view, it is definitely a 'Sunday Flier.........almost ! ' By doctoring one of the images, I was able to clearly define the correct no.of rib bays both wings, position of the top/bottom struts, the span-wise 1/8th square x 3 on upper surface LE of the wings. In another shot, the 1/8th sq. stringers on the turtle deck are clearly visible and the vert, stab. shape is a dead giveaway. Tip shapes and structure correspond. HOWEVER, the black part of the fwd fuselage and the red part above it are NOT per the original. Neither is the under carriage correct . It doesn't look quite long enough. The 'proper' assy. does place the main wheels CL about 71/4" in FRONT of the lower wing L.E. and approx. 41/4" UNDER the lower surface of the lower wing. That's what the plan I have in front of me shows folks !  Dave B, I have been feeling a bit as your Avatar shows ! Edited By ERIC CLAPHAM on 26/05/2017 08:11:25

    Sunday Flier. Edited By ERIC CLAPHAM on 25/05/2017 08:45:34

    Looks awful like a 'Sunday Flier' by M.Conrad. Freebie in RCME Dec.'88.
  23. ERIC CLAPHAM
    I was taken by a photo showing this model with a mid-fuselage, pylon-mounted EDF. Given that the original had a Cox .049 - under-powered perhaps - what EDF would be best matched to the airframe ?

    Simon, No datum line shown.

    Finale - A free plan in the April.88 Radio Modeller by Mike Freeman. The control movements are given as (both pitch and roll) 3/8 -5/8" at the wing root trailing edge. Original weight 18oz. C.G. at 2.75" from the root L.E. i.e. about 0.35" in front of the wing pivot. He had another more orthodox layout plan but still with wing twist, as a freebie in May.86 RR. This was called 'Sequel." Let's know how it flies.Also 'Zippy' tailess elevon sloper in RR April. 87. Edited By ERIC CLAPHAM on 08/05/2017 13:38:43
