Help with identifying an unknown plane(Kit)
trevor wood 2 replied to funflyerColin's topic in All Things Model Flying
Appears to be a Mudry CAP 20 (or possibly CAP10). Aerofred free plan download site has a number of plans listed, but none of this size. -
Forum members' new models: Let's see them.

Well spotted Geoff. There's a group of us who have joined the local cricket club as non-playing members. This allows access to a perfectly manicured flying field and the club house every day of the week. We can even fly on weekends during the cricket season, as matches never start before 1.00pm. -

42" span Antoinette weighs 7 ounces. Rudder, elevator and wing warping. Powered by small GWS geared brushed motor. Max flying speed 4 mph. -

PatMc, Static thrust is a force (Newtons) which equals mass (kilograms) multiplied by acceleration (meters per second per second). Therefore it actually does have an element of "time" in its definition. Static refers to a thrust measurement taken with the aircraft restrained, when the propeller will be working at less than its optimum condition. However, you are totally correct when you say there can be no conversion between thrust and power because the efficiency of the motor and of the propeller will differ from one installation to another, and also because the two parameters are measured in different units (Newton for thrust, and Newton.meter per second for power).

Oops! That would be the LMA show. Sorry. -

Lancaster auxiliary power supply thingy

The Lincoln (and Tudor) had annular cowled Merlins, not Griffons. -
David, I was looking at the Chipmunk photograph at the same time you made your post, and thought exactly the same. The front of the nacelle seems too wide, and the cockpit too tapered/tall. Trevor

Peter, the thought of motorizing it had also crossed my mind. I do recall seeing a civil registered T31 in the mid 70's fitted with a pair of single cylinder air cooled (motorbike?) engines, clamped to the inboard end of each forward wing strut, but haven't been able to locate any photographs. Would you need a twin rating to fly it! A close approxiomation to the real thing wouldn't be too difficulty to engineer on the model with a couple of cheap brushless motors. Terry, I guess today's 'Elf 'n Safety' people might have something to say about simultaneous winch launches on closely spaced parallel cables, but the diagonal rod under the centre section with the blob on the end is intriguing. Would it be an air to air camera mount for taking 8mm cine or 35mm stills?

When I saw the earlier posts, I was reminded of my own ATC gliding course at RAF Sealand in 1968. Was the T31 the only aircraft that took longer to get to 1000ft on a winch launch than it did to get back down? Out of curiosity, I checked the link posted by Peter Miller to the T31M register, and was surprised to see the Mk3 that I soloed in (XA284) stll exists, but now as T31M G-BNPF. I made a 1/5th scale model of the Mk3 some time ago from the Radio Modeller plans (RM125) and the build article published in the March 1974 edition of the mag. It's had a few hops (not much shorter than the full size original) from a bungee, but I really need to summon up courage to throw it off an into wind slope to get it to fly properly.

The RV is flown from the front seat. There's only a limited panel and no brake/flap controls in the back. Unlike the magnificent Biplane and Lucilole above, my friends homebuild is currently at the 90% complete, 90% still to do stage:- The photo was taken last year during the first trial fit of the wings.

Managed to shrink the file size and upload an image of the electrified Colibri built from the 1980's Peter Miller plan. The full size one is in the background......

Peter, thanks for the words of encouragement. I wanted to do an RV4 because a friend in France has been building the full size version in his garage for the last 5 or 6 years. It's my attempt to shame him into finishing it before the oil runs out and he has to do an electric conversion. As an aside, he currently flies a Brugger Colibri which is why I'm now such a fan of your model designs - I saw your plans in the back catalogue and made replica of it. I've not yet been able to get a picture to upload but I'll keep trying. Erflog, the motor is a relatively inexpensive Emax BL2826/06 from Giant Cod, with a 5amp switch mode UBEC from the same source. I'm initially going to try a 5000mAH 4S Lipo with 12 X 6 and 13 X 7 props , hoping for about 550 watts. If that power isn't achieved (or more likely if I start to worry about the current drain) I might change to a 5S/4000mAH. Tim, the front seater is currently the briefing room brushing up on his Pilot's Notes, but rest assured his upper torso/head will be on board for the 1st flight. rgds Trevor Wood

I realise it's been sometime since the last posting, but I've only just found this site. Here's a couple of photos of my RV that was started soon after the plan's were published (I only wish I could build as quickly/efficiently as some of the earlier contributors). The plane looks a bit different from the Pete Miller version - mine is intended to be an RV4. Wingspan is increased by about 15% over the RV3 and fuselage lengthened by a similar percentage, but under the skin it's just the same as the RCME plan. Finished weight is 6lb 2oz so wing loading will be a bit less than Peter's version. First flight still awaited.
