Hi Luke, Stall speed is about 15 mph. The usual routine for the HPAs is to have wing walkers on foot for the launch and then another pair on bicycles chase the aircraft along the runway to assist with the landing. The designer, John Edgley of Optica fame, has been keeping this fairly quiet...

Hello everyone, I haven't been on ES for a while. Sorry about that but I just got snowed under with projects. But even though I really did have too many projects on the go, along came one that I couldn't say no to. I was recruited onto one of the teams for this...

I would refer you to the words of my nine year old daughter. Back in the summer, I took her to see an air race. We don't have proper air races over here any more; we only have handicap races aimed at making the sport more inclusive and accessible. I was half way through explaining the system...

Thanks Luke, I was about to wade into the thread, but you've done it for me. Yes, weight is the key. I'm not so sure about this percentage of the rider's weight though. I try to look after myself and I want my reward for being 150 lbs instead of 200. Surely you would also have to have naked...

I thought we already had a first to file system, at least over here. If there is no public disclosure then it's the date of filing that's important. When I was employed, many years ago, employers would pick up the tab for a patent application. But working for myself, I soon realised the expense...

Thank you, Luke, and no offence taken, Kim. I turn my back for a week to do other things* and I missed all the fun. I had no idea about the fun. I'm still reading the threads to catch up. Sorry for being off the ball. Nick *family member having a domestic crisis. Nothing to do with riots or...

Hi Everyone, I just got a text message from my son. He's touring the USA with a friend and he says it cost more to hire two bicycles than one car. Maybe that's just his way of explaining why they are driving round in a 4WD SUV. Actually, I suppose it could be the same over here. Car hire (auto...

Contactless power transfer has been around for many years. I first saw it in an application where they had to connect and disconnect power cables underwater, so they used a magnetic coupler instead of contact pins inside the connector. There is also the familiar electric toothbrush, with a...

Good luck, Luke. Go for it. Keep the good news coming. Nick

This is what I do with my LVC. Something that just cuts out is a disaster; you want an "analogue" rather than "digital" control. Then you can carry on at whatever throttle setting the system can cope with. Nick

:D Or you could get your manservant to do it. After all, he can't be spending all the time polishing. Seriously though, we do have some peeps using motorised tugs on fairly small planes. It doesn't take much of a ramp into the hangar to make it worthwhile. Of course, what makes a plane really...

We have an annual tug race at our airfield. The rules are pretty loose. Last year the air ambulance crew made a good showing with something loosely based on their helicopter towbar. The winner rode a motorised armchair. I entered a hovercraft. Nothing electric has entered yet, but I'm thinking...

Hey Luke, amazing work well done. So let me get this right. There were two professional superfast motorbikes, a number of other electric motorbikes, and your bicycle. And only the two superfast guys beat you? Nick

That's true if we're talking about the short term peak. For continuous running, the limit is usually set by the heat dissipation. It's a moot point which condition we should be looking at for racing. Is 10 minutes a short term peak, or long enough to melt a motor? +1 for a racing section...

All sounding good so far. If the date works out, then I will come and race. Nick
