|Thread: Chris williams ASK-11|
Hi Frank, can I ask what's the weight of your ASK-11 & what's the power train ?
|Thread: Cutting steel wire|
Ron, if I had the same interest in bikes & motorbikes as yourself I'm sure I'd have bought the same or similar cutters. But since I haven't I'm happy using a dremel to cut steel wire & cable.
|Thread: Hangar 9 P47 repair|
No doubt Geoff will wear a suitably soulful expression as he carries out the electric power conversion.
|Thread: Cutting steel wire|
Ron, I don't think many of us need to cut steel bowden cable often enough to justify the cost of specialised cutters particularly when the ends of the cable are going to be soldered anyway.
Side cutters are only good for "soft" metal they will be damaged first time they're used to cut piano wire & won't last long on steel bowden inner wire either.
I would silver solder a Z bent piece of bike spoke wire to one end of the cable before cutting it. Then tin the area of the intended cut with a small piece of silver solder & cut with a dremel disc. The silver solder can be neatly filed flush with the steel strands in order to be able to slide the cable through the bowden outer. A threaded clevis connector socket is then soft soldered to the cable. To avoid damaging the plastic outer it's best to use a crocodile clip on the inner to act as a heat shunt whilst soldering the connector in place.
|Thread: Voltage sensor|
I bought these FBVS-01 sensors from RCLife. Used with D series Rx's for a couple for pre lipo ESCs on with 3s lipos. One thing to watch is that you only connect to the ESC +ve wire. Don't connect the -ve iwire as it's provided via the Rx A2 plug socket.
|Thread: What can I fly on a 2S battery?|
The max power possible from a motor using 2s is doubled when using 4s but the prop size has to be reduced as the max current the motor can take is still the same.
For sports aerobatic models I usually aim for around a motor of 1000kv when using 3s, for gliders I aim at around 850kv in order to use a bigger dia prop. If I want to use 4s it's simply 3/4 x the 3s kv.
Sports models I go for a battery capacity that will give about 6 mins of full throttle power which normaly equates to 10 - 15 mins normal mixed aerobatic/cruise flying.
I normaly use prop sizes that run at about 80% kv x battery voltage rpm (or less). This is usualy well within the motors current limit.
|Thread: The 2018 Transmitter Survey!|
Bob, perhaps it would be best if you started a new thread with the pertinent points from your previous posts & including the details given above.
Personally I think you may have less but different instructional needs from what most of us have assumed. I also think that you may be typical of a new trend of "beginners" who have multi rotor experience but who now either want to switch to fixed wing models or want to fly both types of models.
I think you're right, Martin.

My advice was based on the information that Bob, the person asking for advice, isn't a rank beginner. He has been flying multi rotor for 4 years and a 2 lb AUW foamy for an undisclosed period. He doesn't say which foamy or what the 6lb model he wishes to progress to.
I'm not saying using a buddy box isn't desirable or even the best option, only that it isn't a necessity, especially given Bob's experience with the probability that he won't need extensive instruction.
Perhaps Bob can fill in the blanks re what the foamy is & what the 6lb model is.
Don, I don't see how it's any more of a gamble than with the instructor on a buddied Tx.
In the event that your choice of Tx can't be buddied, why not ask the instructor to check the model over & perform the maiden flight. Then, if & when he's satisfied that it's OK, you fly subsequent flights with him standing by as per pre buddy lead days.
|Thread: circlips on servo linkages|
I've use them for years on several models, always with either piano wire inner, or metal bowden cable inner, or bike spoke end of pushrods. Never used threadlock & never had any problem.
|Thread: Wing bag material|
During & just before the winter sports season it's worth checking on Lidl & Aldi for snowboard bags.
The ones I have are about 66" long, 13" each end, 17" across centre, strong, zipped end to end, with back/belly straps, shoulder strap & a zipped accessories pouch. They were only around £6 or £7 but I can't remember which store I got mine from.
General arrangement, accessories pouch over centre.
Back & belly strap.
Belly strap moved to shoulder position.
|Thread: Is it possible to create a tiled print out from a pdf file?|
Nigel, in the printer properties options have you selected "borderless" ?
There seems to be an echo in this thread.
|Thread: How to fill a TE / aileron gap ?|
How large ?
|Thread: Do you weigh your lipos (I think you should!)|
Should have gone to Specsavers
|Thread: Taranis limiting servo travel|
Stephen, here are a couple of principles I apply when setting up spoilerons that you might find helpful.
To get the most combined aileron+spoiler travel as well as the most applied torque over any part of this travel it would be best if the servos are moved over their full available end to end limits.
