Latest in Scale Helicopters

Perfect example of why detailed inspections are required.

From the Kraft and Logictrol beginnings in the '60's and '70's, I always dreamt of getting one but I could not afford it then. I bought my first one in 1987, it was a Century 7. Futaba was in the hay with theirs with poor ergonomics but JR's was perfect. Over the years I upgraded to PCM 9 and then custom made PC10sX. It's so natural for flying helis but not at all for 3D and they vanished. For me it's enjoying rc or no rc. So with the help of Roger Forgues, in 2014 I created my first FrSky single stick. And built one for each FrSky update and now use an X20RS my latest conversion. I also designed a conversion for my TX16S II which works perfectly. The MKIII will be done next winter. Flying scale with single stick is heaven and the reason I keep flying at 75. But I do fly mode II when I teach others.

I do not remember when the last time that bolt was replaced. This bolt, P/N 053, is the bolt that is supplied with rotor head P/N 705/30 and is also used on the tail grips to hold the tail blades. The description has G-12 so would guess its a pretty strong bolt. The shank is not threaded so is the correct bolt to use in this application.

I wonder if the slop in the follower was the root cause over time. The follower have been replaced with P/N 68/20 which is ball raced opposed to the pins installed on the original driver. The bolt will be inspected and or replaced on a regular basis moving forward.

UIH,

That is a classic look!!

Thanks.

Great job Danny

It will be fun to watch…hope to meet you out should our schedules align.

Wow!! That is incredible! I had no idea that it was even possible to customize like that. Thank you for that insight and detailed explanation.

Fene's are tough cookies to get right. Tight tolerances and rotational speed limitations make for interesting adventures, especially at my altitude (6,000 feet). This is a great topic to cover.

The best of the best!!!

Thank you!

It is. I’ve bought stuff from them pretty often if I can’t find it elsewhere. No issues so far.

All gears are Vario stock products.

I added pictures to this, but they are not there and there is no edit button. I’m not very good with computers.

That pretty cool. I like it.

Any update on this?

I think that's part of the instrumentation package from test/eval. Other images don't have it. I have gotten the FLIR platform worked out, just need to figure out the FLIR itself. The challenge is that this is only a .30/550 size heli. The nose datalink antenna is only about 25mm tall.

Hello Cletus, the flying weight is 18.7lbs (8.5kg) with the 3 batteries, 2x5000 6S, that i use for everything (motor, servos, received, etc), and 1x1,500 3S that is use for the lights system.
Head speed 1,250rpm, i tried to lower it to the 1,100 suggested but at 1,250 it feel more comfortable, for me, in the way the heli respond. Fly time 8min but the batteries still have 55-60% charge after landing. I hope this help you with your project.

Awesome!

Luckily I was able to place the lipo's next to the mechanics instead of in the cockpit, CG point is just fine now. Lipo's tray's supported directly by the metal frame, so no load on the fuselage.
