Piper Twin Apache PA23 -150 74"
Lindsay Todd replied to Danny Fenton's topic in Own Design Project Blogs
Super job Danny, been quietly watching in the background and looking forward to seeing this one completed, must catch up soon. Linds -
New needle valve sorted from Just Engines, great service, ordered about midday and arrived next day so already installed and looking forward to flying again soon so i guess for the moment this brings this design to a close, plan will be submitted to the mag. Something a bit different next time i think. Linds

many thanks guys, just need to track down a replacement OS70 Surpass needle now, i have spares of a lot of things but not one of these, either that or out with a metal detector although i think i have more chance of finding another saxon gold hawd rather than my missing needle valve. Linds

Finally had the chance for the maiden flight of Rusty Ferguson today and get some photos together I am really rather pleased with this design and with the ground shots out the way fuel up and engine running nicely a few taxi runs were carried out which proved a need for steerable rather than castering tail wheel will be an advantage so i will update back in the workshop. With that noted the model was lined up, power applied and committed to aviation. Some models just feel right and i was delighted to find that this is just one of them. Just a couple of clicks of down elevator and aileron had her flying straight and level and just feel very locked in Capable of all the basic aerobatics and infact probably aided by the deep fuselage produce quite an impressive slow roll showing good rudder authority and pitch control. The old OS70 Surpass has ample power to spare and large loops and steep climbs were easy, although i found myself playing touch a goes quite quickly. The flight curtailed with a dead stick landing which proved the slow speed and stall design characteristics were also a delight. the only issue and cause of the deadstick was a fractured spring steel retainer on the needle valve failure that had allowed the needle to vibrate loose and fall out which curtailed flying. A shame to get just the one flight but was an absolute delight. chuffed with this one and will be one of my favorites i think. Lindsay

Finally got another chance to do some more work on the canopy, inevitably the fit had some areas of shrinkage and expansion so a little filler and sanding was required to loose the edges and get a good clean fit, still a little sanding to do but the fit and look is now just so much better for the effort. good progress and worked so well that i am going to look at some other sections of the canopy as well as the rear gun turret moulding next which originally was planed to be made in two sections but maybe forming in one is worth a go as i already have a plug ready. I'm not going to embarrass myself by saying more soon but its good progress none the less. Linds Linds

Well model now finished and waiting opportunity for test flight. I have pondered adding the wing struts time and time again but I'm really not sure it needs then so for the moment at least i have decided to go without, i may yet change my mind once i see how it looks in the air. Any way i have kept the scheme very simple on this one with basically all white, clear or antique fabric and just a couple of red highlights on the tips and fin. A few panel lines and obligatory rust marks to finish. Oh and of course every crop duster needs a suitable pilot, this guy i think fits the bill nicely Flying shots etc when opportunity arrives, not this weekend i feel Linds

Also a Silhouette Cameo user for several years, can thoroughly recommend and its optical scanner function is also very useful tool. Linds

Plenty of space in the natch for fuel tank or battery, slec tank fitted with loads of space to get set up just right and should provide more than adequate should it go electric Underside of the cowl is neat and tubes for tank and oil bleed from engine exit, these are retain by p clips screwed it the firewall Radio installation pretty much complete, again not short of space. A quick cg test would put the 5 cell sub c nmh battery i intend to use just behind the U/C position so has loads of space and a simply ply tray will be made to fix in place across the fuselage width. Got a bit carried away really and decided to add some purely cosmetic wire bracing to the tail surfaces as well as a logo and bit of rust paint with a name like Rusty Ferguson i figured a few panels and rust marks were necessary I also added some hinges to the right hand door to make it accessible and fitted a battery monitor and bit of a dashboard and of cause a pilot of suitable character although i will save his face till later bit more detailing on the wing, fit the battery and ready for test flights i guess now, assembled shots asap Linds
