Thread: New Drone Laws from 30/5/2018

Posted by Andy Meade on 11/06/2018 14:12:07:

I did see on their forum that someone suggested the 400ft rule should apply to anything powered - I quite like that one, but I know not of what the BMFA's plans are for us.

I don't follow the logic of that point of view though. Presumably the issues of model aircraft flying at altitudes greater than 400 ft are concerned with safety and the possibility of collision with another airspace user? If so, then how does a 4m span glider pose any less threat than a 2m span powered model? Sounds like the glider fraternity wanting to be looked on as a special case!

Thread: Servo extension leads
04/06/2018 16:10:47

I did a little "how-to" article on making your own servo extensions in the mag a while ago. Once you've got the crimp tool and a little practice behind you it really is very simple. The big advantage is you make custom extensions to suit YOU, instead of making do with what's available.

My main car is currently just shy of 206,000 miles! Doesn't burn any oil, driven gently it can manage 40 mpg (though 35 is more usual), can blow off a Porsche Boxster and any BMW short of an M series and carry five people in comfort - though not all at the same time ! wink

Old cars! Don't ya love them! laugh

What car is it Pete - I'm intrigued!

My club purchased one in the last few months. Thankfully we've not had to use it yet!

Thanks Percy, yes, I'd thought about a folding prop. Julian, I think I must just be unlucky, as I land on a mown airstrip and have braking disabled on the ES2's speed controller. The first prop break was, I must admit, on a slightly harder than usual landing. The second though (yesterday) was a perfectly good, fairly slow (as it was quite breezy) landing.

I've put a new prop on so I'll give it one more shot and see what happens! I'm using APC props by the way and they do seem quite brittle.

Has anyone flying the ES2 (without landing gear) has a problem with the prop breaking? My first three flights were absolutely fine. The last two landings have broken the prop. I don't use braking on the ESC and the throttle is idle by the time the plane lands.

Oh Dear God....Here we go again.

Well said Mr. Miller! These "electric vs IC" threads are tedious in the extreme. You might as well start comparing religions as you'll find the same entrenched ideas and unshakeable beliefs spouted with the same fervour. I prefer the motto "live and let live"!

Thread: E-Flite Convergence anyone?
28/01/2018 09:12:03

Thanks for that Jason. I totally agree with your comments and my use of trim while in acro mode was purely to get an idea of how much was required. Back on the ground I was going to reset trim to zero and apply the correction mechanically to the elevons.

I've ploughed through some of the RCGroups thread and there are a few gems of information, particularly around increasing the servo travel on the elevator channel to overcome the Convergence's reluctance to travel backwards in the hover. I also picked up that the LVC programmed into the FC is an issue if your batteries aren't in tip-top shape. As you say though, there is also a lot of "noise" in that thread!

Yes Dave, it is the BNF and I see what you mean about the two aerials - how silly! I'll make the same mod you suggest. Thank you for that.

Tim.

Thanks for the reply Denis. I must admit I hadn't considered that. However, I removed the bottom cover from the fuselage and checked and the flight controller is rock solid, screwed down to a ply plate firmly fixed in the fuz body.

Well worth checking though.

Cheers,

Tim.

Does anyone on the forum have any experience with E-flite's Convergence? I bought one this week and took it up for its first flight today.

It hovers OK and the transition to normal, fixed-wing flight is also drama-free. In "safe" mode normal flight is fine, but..... boring! So, I soon put it into so-called "Acro" mode, where self-leveling is turned off. Here, there was a gentle roll to the right. So I put in some left aileron trim. But, strangely, it seemed to have no effect. I added more, again without much effect. I added yet more and the model suddenly started to climb steeply! I quickly put it back into safe mode and regained control and landed.

I'm puzzled now as to what's going on. On the bench, the elevon movement seems normal.

I should add that there was little or no wind when I was flying.

Any theories anyone?

Nice one Ron!

I have to agree with you on a couple of points - I too found the low rates mentioned in the manual quite exciting enough for me! Secondly, I aborted a flight on Thursday as I just kept "losing" the model against a featureless, dull grey sky. I can't wait for the next good flying day to get it up there again! Lovely model.

Thanks for making me buy it David!!

Cheers,

Well I saw a gap in the clouds this afternoon, so took the ES2 up to the field and gave it its first flight. No dramas - it needed a bit of right aileron trim and a little up elevator. Once that was dialled in it flew absolutely beautifully. On 4S there's bags of power of course and it will go vertical as long as you like. I'll have to add some tape reinforcement to the bottom of the fuse though as I'm not planning to add any U/C. Anyway, I flew three batteries and had great fun! Now I've just got to clean the mud off it....

Tim.

10/01/2018 12:36:24

That's a very ingenious and neat workaround Ron!

Tim.

08/01/2018 18:21:16

I certainly am Bob! Indeed, I've nearly fallen foul of it in the past. Just cos you've got a lot of Watts doesn't mean you have to use 'em all the time!

Tim.

08/01/2018 17:21:49

Yes, I was surprised! I don't think I'll be using full throttle very often Martin!

I ran a full power test on the ES2 this afternoon. Battery was a 4S, 2450 mAh, peak power was 766 Watts, and peak current 49.4A. The final AUW I measured at 2.94lb, so we're looking at 260 W/lb. I don't think it will hang around!

Tim.

06/01/2018 18:21:04

Put the completed model on the scales this afternoon. Without LiPo it's 1055g (2.32lb). I'll be using 4S 2350 mAh batteries which will come in around 270g I think. So the AUW will be about 1325g (2.92lb).

Lucky indeed Ron!

I've ended up relieving a very small amount of material off each lower fuselage corner and now the cowl goes back far enough without undue pressure. The one remaining niggle I now have is that I can't tighten the prop because the spinner backplate is slipping on the motor! This last 1% of the assembly is causing 90% of the problems!
