Plane (apparently not) hit by drone at Heathrow.
Daves42 replied to Tony F's topic in All Things Model Flying
This all started on the 17th April. Looks like a Whittindale "dead cat" to me. -
I have a DJI 450 which I built and have flown very successfully. I found the DJI site and the videos on there extremely helpful in setting it up. It explains how to calibrate your sticks and how to set up the switches for GPS, Failsafe etc. You will have to adjust endpoints to ensure that the switches do what you want. But it's all explained in the videos. Just go to DJI.com and look for the right videos. David

BMFA rules regarding starting electric planes
Daves42 replied to Vinegar Dave's topic in All Things Model Flying
I have a Futaba 8FG and fly only electrics. I was concerned about safety right from the start so used the TX programming to set up a kill switch for the motor, which worked just fine. Then taking it one stage further, I was concerned that I might accidentally flick the switch while transporting to the flight line (and back) so, I changed the assignment from the switch, to one of the rotary knobs, which is almost impossible to move by accident. I have a routine now built into my procedure to ensure that the assigned rotary knob (it is always the same for all of my planes) is in the safe (fully anticlockwise direction) before plugging in the lipo. The rotary knob has to be rotated beyond its midway position before the motor becomes active. I assume that most computer radios would be able to be programmed in the same way. In the pits, the rule is that all props should point outwards away from any people. All take-offs are made from the pilots box except for exceptional circumstances. -
Spring is here!!! Who has been out flying??
Daves42 replied to cymaz's topic in Flying Field Reports and Chat
Hi BD, I saw your tracks in the grass when I got there later. The wind was light and actually got lighter as the morning went on. A good mornings flying. -
I don't like making negative comments but, unlike other people here, my past experience with this company has not been good and I will never buy anything from them again.

What model did you use ?
Daves42 replied to john stones 1 - Moderator's topic in All Things Model Flying
Flair Cub, back in September 1992 with OS 48FS Surpass up front. After a gap of 20 years, now all electric and enjoying it just as much. Don't have the Cub anymore though. -
Here's one I had for a short while in 1993. No I didn't crash it, I gave it away with all the rest of my gear. Waited 20 years then started again. Really loving it now.

Perfect flying conditions here in Hertfordshire after many days of high winds and/or rain. Flew the Acromaster till I ran out of batteries. Weekday mornings as usual a bit lonely but, great flying. David

Hi Stevo, I have a second hand OS 48-FS-Surpass if you are interested. Any reasonable offer would be acceptable. I'm all electric now so, have no further use for it. PM me if you have any interest.

Spring is here - what is stopping you from flying?
Daves42 replied to Martyn K's topic in Flying Field Reports and Chat
Having finally retired from work, I am able to spend as much time as I like on my flying. Today, I went to the field at 9.30am and despite an unfavourable forecast, found conditions to be really pretty good. The wind was light but from an Easterly direction, which is not the best on this field but eminently flyable. Flew the Acromaster non-stop (apart from the occasional landing), running through my limited repertoire of aerobatics, until I ran out of batteries (6) and was back home by midday. The only problem with retired flying is that, during working hours there are few people to share the enjoyment with. I have to wait for the weekends for that. Finally, a question. I really love the Acromaster but, I would like something just as good to fly and still electric but bigger. Maybe around 1.5 metres wingspan. Any suggestions? -
Everywhere I look, they are all sold out. I don't think Hangar 9 make them anymore. Anybody know where I can get one?
-
Thank you for pointing me in the right direction. It does definitely look like a Dave Smith creation but I am now almost certain it is a Saphir. My fading memory tells also pushes me that way. Many thanks.

Today was perfect, though rather cold. In fact there was still frozen water and frost on the site. But, the air was still and perfect for flying. Flew the AcroMaster over and over again. In these conditions it is just perfect. It just goes exactly where you point it. Even my knife edges looked good although, only to me, as I was the only one there. Ran out of batteries after a couple of hours. With a bit of company, it would have been a wonderful morning.

I built and flew this one over 20 years ago but, I just can't remember what is was called. If anyone can enlighten me I would be extremely grateful.

I have 6 x 2200 mAh 3s and 2 x 3300 mAh 4s. All but 2 purchased in July/August this year and used a lot. I am delighted with all of them. I have no empiric measurements to back this up but they appear to perform as well (if not better) than the nano-techs that I was using before. Unlike the nano-techs, after many charge cycles there is no evidence of any swelling and they remain in the same shape as when purchased. At the price, they are great value for money.
-
I have been using the 3S 2200's for the past 3 months. Whilst I don't have any metered measurements, they perform really well in my AcroMaster. Vertical climbs that test my eyesight and up to 10 minute flight times depending on how hard I fly. No sign of any swelling and only come down slightly warm even after quite vigorous use. At £10.50 each, they are really good value for money.

I too have had problems with instructions from HobyKing. Like you, I followed it up and was directed to the files symbol on the model page. All I got was the manual for a similar model but manufactured by Pilot. Like you, I believe that HobbyKing can supply some great bargains but a model kit without at least some instructions, i.e. C of G is just not acceptable.

Following up from your suggestion on aluminium tubing. If you want to save a little money, thick walled aluminium tube is available in various sizes at B&Q. I have recently bought a 1 meter length of 1/4" OD tube (6.2mm) - bore diameter 4mm, for less than £2.50. Cuts to length really easily and seems very strong. Works really well as standoffs for my WOT4 ARTF.
-
Many thanks for all your useful suggestions. I now have a number of alternatives if my original choice proves too difficult to employ.

My Hangar 9 Saratoga came complete with purpose built stand offs to mount the outrunner motor. They are hexagonal section aluminium with a bore of approx 4.5 mm and seem good and strong. I am currently assembling a WOT4 ARTF converted to electric and would like to find something similar to use for a motor mount. I have ordered some Hangar 9 stand offs from Wheelspin Models, which I will cut down to fit my WOT4. Just wondered if anybody had found an alternative to do the same job?
-
I bought , assembled and flew a Wot4 ARTF modified to electric until quite recently, when it suffered a pilot error and is no longer. All the internals were still in good shape and as I was pleased with its performance I decided on a direct replacement. I bought the replacement today, and was surprised to find that the motor mount captive nuts were spaced diferently form last yaers model and that the motor was mounted about 10mm lower than before. This was confirmed by the fact that the cowl from the previous model was totally out of place on the new one. Has anyone else noticed this or can anyone suggest an explanation.
