Spent some time today at the compound just testing and tuning. I have a wide range of airframes covering three flight control firmwares.
  • Strix goblin with custom vectored thrust VTOL pods, running ardupilot
  • Strix nano goblin with ardupilot
  • Volantex Ranger 2000 with ardupilot
  • Chameleon LR 6" frame with iNav
  • Lumenier QAV-R2 5" with betaflight

In the past I've never been happy with the "autotune" of ardupilot. I would typically try it, get some values, and then revert and try manual tuning because it felt sloppy. Today I changed the autotune_level parameter from default of 6 to 8. It warns that 8 is for advanced pilots. I have to say I'm extremely pleased with the tune that resulted. In my opinion this is what the tune should have always done. Worked great on my nano goblin and ranger 2000, which are very different platforms. I'd recommend everyone who has a plane that flies in FBWA to try autotune level 8.

iNav... A couple years ago I posted about my experiences with iNav vs ardupilot. Long story short I had inav on my goblin(non vtol) and after several major crash sessions I swapped to ardupilot and haven't gone back. Since inav started as a betaflight fork I decided to build my new chameleon frame with iNav for RTH and arrow home features. There seems to be a major issue with altitude calculation in inav. In the megathread 747TestPilot did a lot of work trying to get altitude to work. I have spent 8 batteries tuning inav, and am also having serious altitude errors. It will swing hundreds of feet in an instant, usually going negative. I'll do another write up with more details but at this point I'm leaning towards flashing ardupilot to see how stable it behaves.

Quick video with the ranger after autotune level 8. It's so locked in I finally felt comfortable skimming tree tops.

A buddy and mine picked this up at the local scrap metal heap at the tip.
After dismantling and inspection, I decided it was in surprisingly good order inside, despite the rough exterior condition.
I have cut it down in the usual way, increased the compression ratio and adjust the port timing to suit.
I made a spark plug adapter to fit a CM-6 plug, as the 14 mm plug that it came with stuck out to far near the plug when the lead was fitted.

Latest version of the Alfa Corsair retracts. I haven't flown this for some time with the wing modified for flaps/retracts as the earlier version of the retract actuation became more and more unreliable.

Thanks to a bit of spare time lately with our airfield closed due to COVID-19, have pulled the wing down from the shelf for some more tinkering.

This looks quite promising - very robust and reliable. Was able to replace the HS-81MG servo (17g) with a lighter Turnigy TSS-10MG (10g) - so maybe a neutral impact on weight allowing for the bell-cranks but removing the flexible Gold 'n Rods.

So I had this nice pair of Flyzone Beaver floats, with no plane to put them on, and got all inspired to pull down my dusty old 53" Easy Built Pilatus Porter kit from the stack. The kit is cheap, but builds up into a rather nice model, really. It is meant for electric power, but I thought it would be more fun to have at least one glow engine powered floatplane in my fleet of water birds, so I tossed the cheap vac-formed cowl in the trash and made a proper flat-plate mount for my OS10FP. I have a half-dozen of these engines, and they all run great. Not a lot of power, but reliable. I like that.

Today, however, I decided to maiden the Pilatus off the grass runway, with the optional wire landing gear I made for it. No sense letting a perfectly good model sit on the shelf and wait for the float-fly to come along. The little OS10FP was a bit reluctant to pull the Pilatus off the dripping wet sod, but once clear of the ground it climbed out nicely. I wonder if it will have enough power for water flying with the floats. If it needs a bigger engine, I have a Magnum .15 that will drop right in the same mount, with some minor hole relocations. Anyway, the OS10FP is a good match for this 32oz model, and I flew around for most of the flight at partial throttle. Loops were effortless, the stall was tame as a lazy house cat, and the landings were floaty and easy. I will need to move the mains forward another inch, though, as I couldn't keep the Pilatus from tipping on its nose in the last foot or so of the rollout. (I should have seen that coming. My usual rule is wheels no further back than the leading edge of the wing.)

What fun! A hybrid sport scale floatplane/landplane, for some relaxing S.M.A.L.L flying out at the field. Now I can't wait to hit the lake this summer!

During my time hunkering down due to the Coronavirus pandemic I have returned a Carl Goldberg Super Chipmunk to flying condition.

I picked up the airplane at the Westminster Maryland RC Swap Meet in 2017 or 2018, until recently I haven't had time to get it ready.

This airplane has been built immaculately, it is covered in monokote in the traditional Art Scholl scheme.

The airplane is fitted with an OS 91 Surpass II 4 Stroke Engine; stock muffler; Zinger 14 x 6 propeller; Futaba servos; Futaba S3008SB receiver and Futaba 10J transmitter.

During set up of the airplane I discovered the prior owner left behind a nice microswitch activated glow driver. I just had to trim the throttle servo arm slightly to ensure that it only comes on at or below 1/4 throttle. It is activated by an on off switch on the outside of the fuselage. When the airplane is not in use I make sure to leave the throttle servo at 1/3 throttle or higher to avoid engaging the microswitch in case the external on - off switch should get bumped. The sub C cell that lights up the glow plug was still OK, I was able to charge it and it does hold a charge.

I did make some modifications to the throttle linkage, it is the type that goes out past the carb throttle linkage and then hooks back to it. As it was it went out a little too far allowing the piano wire to flex some so it did not open the throttle correctly. I cut some of the wire off and shortened up the linkage back at the servo arm to account for

About six months ago I bought my first kit: the GWS AT-6 (EPS version). They're still relatively abundant and inexpensive, so why not?

I've chipped away at it for all this time, often waiting for parts, usually waiting for corrections to my mistakes to dry/set/whatever. Throughout all of this I've messed around with other planes in order to figure out many of the skills I'll need to actually fly this thing. Now that I have all the pieces, to include Tx/Rx/battery/motor/ESC/etc., I've turned a corner inits completion and am nearing the maiden, which should be this month.

Why I insisted on flaps and retracts on my first build...well, it's probably because good planes with them are so relatively expensive and I wanted those features too bad to fly this thing without them. This has cost me time and money, and has led to several mistakes that have caused significant delays. Namely, using the wrong epoxy at one point, despite reading the threads on this plane that warned against it. I thought I was careful, but I wasn't. This led me to learn about Foam-Tac, which is a great product, but not as easy to use as others make it seem.

Other challenges come from my fear of the wings splitting apart, brown outs, bad soldering, or just bad flying. Alleviating these fears cause more delays.

Then the retracts themselves. I just couldn't get a set small enough to not protrude beyond the wing surface, so my solution is inelegantly permanent. A failure will be a problem to say the least.

So after no further ado, here are a few pics of the progress so far . I'm yet to paint the beige parts or any part of the wing, but I have primed everything and installed all the servos, most control fittings, and protective shields for underwing components.

During my time hunkering down due to the Coronavirus pandemic I have returned a vintage Joe Bridi Dirty Birdy 60 pattern airplane to flying condition.

I picked up the airplane at the Lebanon PA RC Swap Meet in early March - that was one of the last normal things I was able to do before the onset of the pandemic.

This is a kit built verion of the airplane - it has been very nicely painted by it's prior owner.

The airplane is fitted with an OS 61 SF Engine; stock muffler; Master Airscrew 12 x 8 propeller; Tru Turn spinner; JR Servos; Futaba S3008SB receiver and Futaba 10J transmitter.

The prior owner said he did fly the airplane with an OS 61 size engine - that is true because the 61 SF dropped right into the airplane and the Tru Turn spinner with it's flush backplate fit right up to the nose with about 1mm or less clearance. That is as close as I would ever want the spinner to be to the airframe.

The prior owner did add some weight to the rear of the fuselage - after fitting my gear to the airplane I did find that it was a little on the nose heavy side but not unacceptably so. The battery pack is mounted behind the servos in the fuselage as far back as I could get it without having to do surgery (it sits in the main fuselage area toward where the wing bolts are - its securely mounted out of the way to the top side of the inner fuselage).

I fly off a grass field so I ditched the small wheels that were on the airplane in favor of 2.75" wheels. There's a

Yep Les Amis,
Mon BETA préféré pour l'instant ! Ok, je n'ai pas choisi le bon jour pour tester ce nouveau Tiny de chez BETAFPV ... 60km/h de vent c'est environs 40km/h de trop pour ce petit BETA65X ! Bien sur, je ferai d'autres images (avec plaisir ! lol ) par temps calme, pour que vous vous rendiez compte de ses possibilités. En attendant, croyez moi sur parole, il est très performant en extérieur et surtout, très résistant.
