Pity about the engine people messing you around especially with so much money involved.
As for people disagreeing - don't let them get to you, they are just jealous that they don't have the skills to get anywhere near that fast!
Well done for all you have achieved and I hope the engine comes back working soon.

Bad luck about the engine - I seem to remember you being in this position before?

I wouldn't get too down about the naysayers - you know what they say about Tall Poppy Syndrome ... you stick your head up and everyone tries to drag you back down to their level. As long as you know the truth and can demonstrate it to the best of your abilities with the hardware you have, I would say it's on them to prove you wrong. Simply arguing "that can't be because we can't do it" is nonsense ... if it makes them feel better then I guess there's not a lot you can do. Haters gonna hate!

Keep it up Rupes, a lot of us have followed what you do for years - your integrity isn't in doubt here.

Hey chaps! Quick update.. still waiting on the return of my jet engine. Martin at Lambert turbines told me it would take 1-2 weeks to repair and do the service, and made me pay for the repairs in advance.. that was over 4 months ago. I have called many times, emailed etc.. and been given multiple broken promises. Really, really shocking service with so much money involved. It has totally stalled that project. The latest promise is that it will be shipped tomorrow, so we will see. There are forums and Facebook pages full of other customers with the same hateful customer service. I am regretting choosing that engine now, the total bill so far for just the engine is £3,350, and it only flew once, and I don't even have the engine anymore. Just got to keep my chin up and hope for the best.

Have found another possible site to fly the 14s plane when the weather gets better, it should allow a nice low pass over some timing cameras. I am not going to start any other projects until the jet has either made another run, or been sold without an engine.

Will update if the engine does indeed get shipped tomorrow.

With regards to the front prop, I asked an expert about this, and from wind tunnel testing, a front prop should work better, as the flow speed into the blades is more constant across the span of the blade, so the prop will run more efficiently.

However I believe that there are some other considerations such as the thrust of the prop in a front configuration being forced into the drag across the airframe, causing separation and turbulence, this has to lose a fair chunk of thrust speed.

I also think that whilst the air entering the prop is more turbulent in a pusher, it is eating some of the wake drag caused by the fueslage and giving the prop a narrower column of air that it is outputting (which will be moving faster) rather than it being more dispersed having encountered separation over the airframe.

500kmh has made some people in the speed community pretty upset and has led to me being insulted a few times, as they do not believe it is correct, as their previous testing of delta pushers showed poor results. However they were not 14s and 9kw!

With LOS speed flying it is necessary to make sharp turns, which with a delta will bleed off a LOT of speed, but with FPV, I do not have that problem. But my explanations have fallen on deaf ears, they have their way, I have mine. So I need to verify the results better so I can call them out. I am convinced of my speed as I have got there incrementally and my GPS readings flying in a straight vector like I do, have always been very consistent. The same setup in the same plane will always read within a few KMH every run. It is not possible for me to take my plane to Germany and do a 4km run legally, otherwise I definitely would!!

Hi Friends,
Am new to this forum and also to autopilots. I am looking for some pointers on how to integrate a camera with autopilot. I searched this forum threads and made sure am not duplicating. I couldnt find the answers I need. I appreciate if some one can help me.
1. How do I control my camera shutter (remote shutter) from my tyranus with my autopilot. I have 2 autopilots (MFD & Pixhawk). I would like to take still images every 2 secs or 4 secs whatever the interval I set.
2. This is independent of the first one. How do I control zoom of my video camera from my tyranus and autopilot? What configurations needs to be done.

Thanks in advance!

I keep loosing the bind and have to rebind every time I power it on.

Cheers Steve,

Since all that with the CAA and registration, a lot of us decided to stop what we were doing.
Now that Joe-Public are starting to see the other side of certain authorities, they are slowly starting to get back into the hobby.
I still got all my gear, plus all the new gear and have decided to restart what I love.

Hope there are a few out there that will join us!

There's a good tutorial by Painless360 about DIYing a headtracker and it seems to work nicely.



(Welcome back Anthony!)

Reminds me of an experiment I did with my old TBS Discovery and two old 2200mAh lipos that were past their best...

Using each battery individually, if I throttled up the quad the voltage dipped dramatically and the flight time was next to nothing.

If I put them in parallel and used both at the same time, the voltage drop was minimised because they shared the current demand between the batteries (so in effect the drain was halved). I was able to use said batteries together for a while instead of binning them.

I made a wireless one that fit inside the goggles case and a tiny receiver inside your radio, worked fairly well, had some tweeking to do but never got back around too it. I might look into doing that again.

Yeah do that, would be interesting to see if it works.
Tom over here made one that fits on top of your gogggles with a wire down to the radio, ch 6 and 7 I think but for some reason there was alot of drift.

Ordered the Fatshark head tracker, I want to try that again.
