1st Solo 8-10-19
Did my first solo on Aug 10th thanks to Dave and Bob, two out of town flyers who happened to be at my field and where nice enough to give me some pointers. Dave co piloted with me for a few flights after Ben, our local "trainer" let me take the club trainer up the previous weekend.

After I had Dan take up the plane and trim it out, I landed it after I few it under his supervision. The first sideways bounce began to tear apart the undercarriage. Did modifications using 1/8 music wire to replace front strut utilizing the front float mount slot and a coat hanger to provide back support attached to the rear float mount. Used wire and solder to attach front of coat hanger to front struts and then used nitro fuel tubing to act as shock absorber between front struts.

My first task is to practice touch and go's so I can get over being so paranoid of landing, particularly in the wind. Most of my flying has been in 10 mph with a Timber 1.5m foamy ARF.

4-5th flight
Crash 1
- Cartwheel (Minor slow speed) - disoriented as to where the end of the runway was making a N. bound approach, plane does a cartwheel before the end of the runway due to stalling about 3-4' off the ground.
Repairs - Landing gear had to be straightened.
Analysis - better to land smoothly in the grass off the field than to push getting onto the runway, better for the plane and my nerves. New gear holding up well.

8th flight
Crash #2
- Nose Plant (unknown - likely moderate...Continue Reading

Based on a glider airframe, the Messerschmitt Me 163 Komet was a German rocket-powered interceptor aircraft. Designed by Alexander Lippisch, it is the only rocket-powered fighter aircraft ever to have been operational and the first piloted aircraft of any type to exceed 1000 km/h (621 mph) in level flight.

Over 300 Komets were built, but the aircraft proved lacklustre as an interceptor it only destroyed between 9 and 18 Allied aircraft against 10 losses. Aside from combat losses many pilots were killed during testing and training (Wikipedia).

To reduce weight, a pair of front wheels were attached to a dolly that would be ejected after takeoff. Once the Komet had run out of rocket fuel after the attack, it would glide back to base at high speed and land on a skid.

Flaps were introduced on the production model (B) in an attempt to reduce speed prior to touchdown.

The Phoenix version is based on a SketchUp model that seems no longer available.

The model an be downloaded here.

Hi all,
I am having difficulty getting this build blog going. It seems like I have a lot of views, but absolutely no responses from any of you. It defeats the purpose of a blog for me as I am looking forward to interaction. There seems to be a problem at RC Groups as it appears as if nobody is able to respond. I need help from someone to contact RC Groups and let them know.

Check out my build progress below...

I suggest reading a small review about the SWR meter and spectrum analyzer with generator, interesting and not expensive "Arinst" devices, for working in FPV. Here, the forum engine did not allow placing open pictures inside the text, so I made a publication on another fpv-community forum.

JJRC H31 Quad MOD Part2 - Beecore BetaFlight Setup!

Here is a link to the Video:

I have wanted to perform this MOD for quite a while on my JJRC H31 Quad but higher priorities pushed it back.
I wanted to a have a Toy-Grade Quad to fly around the property when time doesn't allow for packing everything up and heading to my Flying Area.
Tiny Whoops are a blast indoors but not that great outdoors.
I chose this Quad because it can handle light wind outdoors and it's very durable.
Those of you that have watched my videos Piloting RC Aircraft know that durability is a must for me ;-)

In this video I will show you the changes I've made in the BetaFlight Configuration and a composite of two Test Flights I performed with this setup.
This should give you a good starting point in BetaFlight and then Tune to your flying style.

Part 3 will show an FPV Flight once the FPV Camera is installed.

Here are links to the Components used in this MOD:

JJRC H31 Waterproof Headless Mode One Key Return 2.4G 4CH 6Axis RC Drone Quadcopter RTF

JJRC H31 RC Quadcopter Spare Parts Battery 3.7V 400mah

Eachine Beecore Upgrade V2.0 Brushed F3+OSD Flight Controller For Inductrix Tiny Whoop E010 E010S - DSM2/DSMX Receiver

Turbowing 5.8G 48CH 25mw 700TVL 1/4 CMOS Wide Angle FPV Camera Support OSD NTSC/PAL Switchable

See you in the Air!

Hi! I'm Qwenther.
I'm mildly new to rcgroups but not new to the hobby, and I'm so excited to share my RC experiences. To start with, I just did a major overhaul on most of my aircraft. Some have been in the shop for awhile and some have only needed repair for a week. Either way they needed some TLC. As soon as the weather calms down, I'm looking forward to putting some of these birds in the air.
