I had the same experience with my first FunCub. As designed the power wires are quite close to the edge of the motor casing and eventually did short out.

Funny you should mention that! I got a Fun Cub from my boy. He had replaced the motor. On the original motor, the wires were practically in contact with the motor housing. These wires were only insulated by their coating at that point, no additional plastic sleeve. Nasty! I may again use that motor ( cheap,  cheap) but will always be wary of how it gets installed in something.

Did someone pick up a Pulse 3s 2200 mah battery from the clubhouse this morning? Please let me know if you did, it’s mine.

Buy, Sell, Trade or Give Away / Hobby King Order?
« Last post by Deerslayer on December 16, 2018, 08:44:56 AM »
Any of you folks planning to place a Hobby King order?

If so, I would appreciate adding in a dozen or so servo repair kits.

I repair any HXT900, HXT500 servos, as well as various HiTec, etc., which suffer broken gears.

Why? Because I am a cheapskate, it is a 5 minute effort which I enjoy and the result is a better than new (little trade secret there) servo.
A gearset costs about $1 - still cheaper than spending a whole $3 or $4 for a new servo.

Meanwhile, don't throw out your broken servos, I will take them off your hands. In fact, if it is just stripped gear(s) and you supply or pay for the required gearset, I will rebuild it for you and apply my world famous "tail light warrantee" coverage.

General Discussion / Warning - electrical issue!
« Last post by Deerslayer on December 16, 2018, 08:17:17 AM »
Recently, I "repackaged" my Optera (reminder to self, when you take your eyes off a white wing at high altitude, even for a couple of seconds, you may not be able to re-acquire said flying object!).

When I was removing the hardware, guess what I noticed at the spinning end! (Photo attached)

This particular situation could exist on any installation but may be difficult to detect. In the case of my Optera, which was 2 or 3 years old and well used, the leads from the motor must have been jammed into place at the time of assembly. One of the three was rubbing against the rotor, resulting in the wearing away of the blue anodizing and, more importantly, the insulation and underlying wire, being worn down.

Now, this poor installation could just as well have worn down more than one of the three wires. Had that been the case, something bad would have happened. In the worst case, fire! In the not so bad case, the ESC and structure itself would have been demolished. LiPo fire, anyone?

Although this was a factory installation, buried well within the aircraft's structure and impossible to see without major disassembly, it could happen with other setups.

One lesson that I have learned is to carefully inspect any initial installation prior to first flight - if at all possible. You are usually dealing with a very high energy density system.

General Discussion / Apace - the final frontier

It's getting closer, at least for those who have some serious coin. Here is the latest development, where SpaceShip 1 officially reached space (non- orbital ,of course, but pretty good anyway!). The accompanying video is excellent, you get to see inside the hangar, in flight, etc. Enjoy!

Wouldn't it be a nice group project to build a model of the mother ship and the space plane? We could pretend that "outer space" starts just a half dozen trees high, right? Awhile back, Andy Kunz of Spektrum fame, built an r/c replica of one of the NASA lifting bodies. Although not all that great in flight, it was a really cool project.

General Discussion / Flying the big jets - from a test pilot's viewpoint
« Last post by Deerslayer on December 07, 2018, 09:13:15 AM »
For anyone who is interested in big aviation, test and certification flying as seen through the eyes of the best, here is something to enjoy. The podcasts are long but certainly not boring! I download them onto a thumb drive, phone, tablet, etc., to enjoy while waiting for an appointment or while puttering in the shop.

“The test pilots’ test pilot”, former CAA Chief Test Pilot D. P. Davies talks about his early career first training and then serving in the wartime Fleet Air Arm, including reminiscences of the naval test pilots course, the Empire Central Flying School at Hullavington and the Handling Squadron. He recounts flying the Fairey Swordfish, Fairey Barracuda, Blackburn Firebrand, Grumman Avenger, Hawker Sea Fury and Supermarine Seafire. During the post-war era, he was "the man" whose word was the ultimate in accepting new aircraft into British service.

I bought his book
Handling the Big Jets:
An Explanation of the Significant Difference in Flying Qualities Between Jet Transport Aeroplanes and Piston Engined Transports

way back in 1973, as a byproduct of interviewing for a job at the NRC's National Aeronautical Establishment.

Although directed toward air transport pilots, it is quite readable for others and remains an extremely popular book amongst the originally intended audience. It is still available through Amazon. I could never have imagined that, 6 years later I would have a future air transport pilot and production Dantest pilot in my family. He found this book to be very useful in his flying career. The down side is that some of his cohorts have also found MY copy to be useful and I am having a difficult time reeling it back into my collection!
