I'm a virgin on here so be gentle. My question is, At 5000 ft in Denver Colorado pulling 5800 rpm on a Vess 24B prop, with a brand new DLE 61 & Brison wrap around muffler, will I have enough Static thrust to comfortably fly beginning 3D? My plane is a 31% Pilot Edge 540 V3. Tops out At 18 3/4 pounds.

Hands-On with Skydio R1 Autonomous Drone! (22 min 3 sec)







Really impressive demos from Skydio in Redwood City. Quad copter startups have been hit or miss & it looks like the same pile of plastic scrap that every startup besides Apple produces, but what they showed here was exactly what I wanted to do for years, with ground vehicles. It looks like it could really navigate most of the mobs I have had to navigate manually. They showed it briefly flying in front of the athlete, despite not having prior information about where the athlete was going. The flight time is undoubtedly very short & the $2500 is almost 1 month of rent.  As a $2500 consumer quad copter, it has no chance, but it would have a chance as a kit allowing developers to add autonomy to ground vehicles.


They're the 1st to consolidate a lot of the bits of research that were done in the vicon rooms for the last 10 years, into a complete product. They emphasized the demo of the fixed wing flying in a parking garage.  It's the 1st time anyone has shown the NVidia TX1 doing anything besides raising its stock price.


Not sure how well it would translate to a ground vehicle, because a ground vehicle needs to stay on a certain path. Prior knowledge of roughly where the athlete was going & where the path was might allow it to do the job. Suspect GPS has not improved enough to stay on a path without some other input.


It wouldn't translate well to a Casey Neistat application. His interest is...Continue Reading

After watching some Youtube tutorials I realized that 1/ those people are completely amazing model builders and 2/ I lack the patience and motivation to try to reach that level.

I picked up some tricks and then embarked on my typical impressionist spree, using paint, brush, toothbrushes, Brillo pad, knife blades, tiny screwdrivers. various marker pens and makeup powder.

Various stickers finished the job, the part numbers and Japanese text from the CC01 ended up on the co-drivers pad!

So far I was ”done” twice but could not resist another go so this is the result as of now. It became more fun the further I got so I can understand the appeal of painting figures and dioramas!

Greetings my friends. I’m going to take a short deviation from the electrical system and go over the propulsion system that I introduced in Electrical Systems, Part 1 and expanded in Part 2 and 2A.

By propulsion system, I mean the propeller, shaft, and interconnect mechanism between the electric motor and propeller shaft. Because the propeller I have chosen (Raboesch 157-14) has a limitation of 5,800 rpm, I knew that I would not be able to do a direct hook-up, but would need some gear reduction to convert motor rpm into propeller rpm. To use a gear-tohas multiple -gear reduction system requires high tolerances and is potentially noisy since I would have to use spur gears (straight teeth – only one tooth engaged at a time) rather than quieter hypoid gears (2 or more teeth engaged at a time). I found www.SDP-SI.com which has belt drive components (as well as other types of drive components).

I used HTD profile belts and pulleys for the testing I did with a gear ratio of 2.27:1, which actually oversped the propeller by about 122% at 31 volts (limit of the power supply). I did some additional design review as I was getting ready to order the pulleys and belts including reading technical data provided by SDP-SI, (I won’t reproduce it here, you can go on line and look under Technical Resources). I chose to change the belt profile to the 3mm GX2 because if can handle to horsepower and it is a thinner profile. This allows for smaller drive pulley (on the motor) and a...Continue Reading

The Kadet has a place in the workshop and I've resumed building the Slow Poke. My first task was to build the servo box in my completed wing panel. The plywood servo tray is far to large for the small servos I'm using and I was able to cut off a good amount of it to reduce weight. After that I started work on the other wing panel. With luck I'll have both completed by the end of week.

Obsolescence has been a big problem for reusability. They haven't been able to recover any more Falcon 9's lately, because of the plan to switch to block 5. If a product evolves too fast, there's no need to ever reuse it. They'll retire the 1st reusable Falcon 9 after only 26 launch attempts.


In 4 more years, they want to have the BFR doing all the satellite launches, but after Falcon Heavy launched, Elon sounded eager to continue improving the old Falcon 9. So maybe in another year, it'll be a Falcon 9 with longer 2nd stage that replaces block 5 & makes recovering block 5 worthless because of obsolescence.

In this video I do my outdoor Maiden Flight Review of the JJRC H23 Flying Car Drone Quadcopter. I drive it, fly it, and go over its pros and cons.

JJRC H23 Flying Car Drone Quadcopter Outdoor Maiden Flight Review & Test Drive (6 min 11 sec)

Here are the review notes for this RC Drone Flying Car:

Pros:

- It looks really good
- It flies very well
- The lights are bright enough to fly in the dark
- The battery type is readily available
- It has good speed in car mode compared to the Syma X9
- The flight times are very impressive! I got 9 minutes after doing tons of battery draining flips!

Cons:
- The flight mode switching is quirky after the initial bind

I am building a nerf turret and I need good servos that can limit how far the turret moves. I saw some on Youtube and Online that use the MG996R but I bought four of them and they did center or limit their travel. I need 3 servos for the best quality and price. Thanks in advance.

No Limit R/C Monster Truck Racing - Newport News, VA Hobbytown Feb. 10, 2018 (4 min 9 sec)


This video has taken a week to complete because I had a memory card failure and lost all the footage. I spent 2 days and more money then I wanted to trying to recover it. No Limit R/C of VA puts on a good event and the racing was fun to watch and be a part of. Thanks to my buddy Al who was visiting and willing to come to the race...and also help film.

The corrupted files that were restored aren’t perfect and were hard to work with, so I did my best to show something for the day. I also couldn’t restore all the files because some were completely corrupted and it was too expensive to get every file.

Sixty-six people are feared to have been killed in a passenger plane crash in the Zagros mountains in Iran. The Aseman Airlines plane, en route from Tehran to the south-western city of Yasuj, came down near the city of Semirom in Isfahan province. The Red Crescent deployed search and rescue teams to the site. The airline has retracted a statement saying definitively that all aboard were dead. Flight EP3704 left Tehran at 04:30 GMT, and crashed about an hour later.

It has been a long time between blogs! As time rolls on I have discovered life gets in the way of a number of my leisure time activities. When we sold our property at the RV resort and our last RV I find more time to devote to activities unrelated to my RC hobbies. While still involved I am just not getting out to go sail as in the past. A lot has to do with not having lakes in my backyard anymore!

Now I am like most RC sailors that have to load up my vehicle with all my equipment and boats I am planning on sailing that day. In a word it has become work to go sailing. Never thought I’d ever say that! I like to take at least two boats with me so that limits which size boats I can get in our small SUV. That translate to being one 1 meter sized boat and another like my Micro Magic or DF 65. I have been able to get my V32 or my Nirvana in there but that’s about it. I recently sold my Motor Life Boat which was very a very difficult decision. I loved that boat. It had served me well as my go to rescue boat when one my wind powered crafts ran into trouble on a lake. I still have my Classic Chris Craft as an alternate. They came with only a forward ESC from Pro-Boat but I swapped out the ESC with a forward and reserve model. This makes the boat capable as a rescue boat. So all is not lost and it fits nicely on the floor of the car.

I have begun to sell some of my treasures realizing that I am not going to be using them as in years past. It is a challenge to let them...Continue Reading
