martin collins 1 Posted August 21, 2022 Share Posted August 21, 2022 Maidend my KI-61 this afternoon, lovely smooth flyer and nice slow landing speed, needed a fair amount of left aileron trim, found a slight twist in the left wing despite the wings being pinned when building to get the correct washout. The wings only have a top skin (Jedelsky wing) so can be twisted quite easily, will steam it over a kettle to take it out, should sort it quite easily. 7 Quote Link to comment Share on other sites More sharing options...

John T Posted September 15, 2022 Share Posted September 15, 2022 A few months ago I decided to have a bit of a clear up in my work room as it had got to the point where I couldn't actually see any work surface. In the process of doing this I unearthed an old Mercury Galahad kit that I'd never built. As it must have been about 40 years ago that I bought it I thought that perhaps it was about time I actually built the thing, so here's the result. The original design was intended for 1 to 3 channel radio. I used rudder, elevator and throttle on mine. Ailerons are unnecessary and I don't think they would work very well anyway with all that dihedral. The engine is a PAW 19 diesel and I've covered it with Hobby Craft tissue over Doculam laminating film. The first flight was unusual in as much as it didn't need any trim changes at all, a rare event for me 🙂. After being warned about marginal rudder authority by a club member who had built one a few years ago, I'd increased the rudder by about 20%, which seems ok for this type of vintage model 8 Quote Link to comment Share on other sites More sharing options...
Keith Billinge Posted September 15, 2022 Share Posted September 15, 2022 (edited) My latest project flies very nicely...The Lidl glider with twin 1806 motors and 3S power this was a spares-box special. 3D printed nacelles and 5g servos. Carbon spars and hot glue! Great fun and no expense was given! KB Edited September 15, 2022 by Keith Billinge 1 Quote Link to comment Share on other sites More sharing options...

John, There was an article in a booklet published by MAP in 1962 called RC4 which contained an article by the Galahad designer Frank Knowles on how to make the aileron modifications...

Piers Bowlan Posted September 16, 2022 Share Posted September 16, 2022 Interesting that Frank said the rudder was more sensitive with less dihedral. Counter intuitive perhaps! Thanks for that Andy. Quote Link to comment Share on other sites More sharing options...

It certainly makes me appreciate the small plug & play R/C gear we have now. 3 hours ago, Piers Bowlan said: Interesting that Frank said the rudder was more sensitive with less dihedral. Counter intuitive perhaps! Thanks for that Andy I must admit that I'm surprised about that myself Piers. One of my other vintage models is a Wee Snifter that was designed for either free flight or single channel R/C. This has a similar layout to the Galahad but on a smaller scale. The designer said that the dihedral should be reduced by half for the R/C version, which I did. It does look better like this, however, the rudder authority is marginal at best so I only fly it in very calm conditions. One day I may get round to building a wing with a bit more dihedral for it. 3 Quote Link to comment Share on other sites More sharing options...
cymaz Posted October 5, 2022 Share Posted October 5, 2022 Just purchased this 87” Pilot RC Pitts. Here is the maiden flight I did for the previous owner.....it’s now mine !!🤗 4 Quote Link to comment Share on other sites More sharing options...
iflylilplanes Posted October 5, 2022 Share Posted October 5, 2022 I built the Top Flite version of this Ken Willard classic in 1974, it was a great trainer, I managed to score well over 1000 flights before a radio failure re-kited the model. Then "The Sometime Build" came up on RCGroups, and the Top Dawg was always a model I was going to build "Sometime", now, I had an excuse to build it. Here is my Sometime Build of the Top Dawg it's a scratch build off the Top Flite kit plans, using the 10% wing section option shown on the plans this time. The changes I made are, bolt on wings and main gear, radial mount the engine sideways, a solid 3/16" balsa tail-plane and a nose to wing engine cowl/hatch. I will be flying it as the original, RET, rudder, elevator and throttle, power is an OS Max15. The Top Dawg and a previously built Royal Coachman are the first scratch built model I've built in over 15 years, and the first IC models I've flown in 10 years. Loving the hell out of building and love IC, even the cleanup at the end of a days flying. Dave 2 1 Quote Link to comment Share on other sites More sharing options...

Anders Wellsten Posted October 27, 2022 Share Posted October 27, 2022 Chris golds TB-3 Scratch built from plans. A first for me, to build a 4-engine plane. Some scale details to add, eight 3-d printed exhausts, air coolers and streamlining for the landing gear. The model is slightly modified from a bomber to an arctic explorer. The original plans incorporated some foam which i changed to balsa. I changed the open cockpit to a closed one. With references from photographs. Flies well with lots of presence Anders 12 1 Quote Link to comment Share on other sites More sharing options...

Graham Davies 3 Posted November 13, 2022 Share Posted November 13, 2022 This flew today. Fantastic afternoon in great weather and in great company. 56" span CAP232, built from foamboard, ply and B&Q pine (6mm sq, for the spars). A bit porky by my standards at 5lb, and flies on 4S 3700 on a 4250 500kv motor and a 14x6 prop. Undramatic maiden flight, with just a few clicks of aileron. It flew really well, although some spurious issue (as yet undaignosed) prompted an emergency landing off the strip. No damage though, and she'll fly again...
