Unfortunately, despite having entered several competitions I have won one. As a magazine subscriber I think we should get a free one! Shaunie.

Excellent! Do you know the production date as it didn't seem to be in the credits. Just to show there is nothing new under the sun as they say, a flying lawnmower, on control line! Shaunie.

I use one for priming my glow engines (ones that aren't cowled anyway). Can't be having with crank it until it draws the fuel through malarkey. Shaunie.

Make a push-pull linkage with say a brass tube outer and support at each end is acceptable. But a snake is by definition flexible and under a push loading the outer will try to bend if it is anything other than absolutely straight. Put another way, if the snake is curved between supporting points when the inner is under compression it will try to belly out, pushes against the inside of the outer which, as it is flexible also stretches outwards, end result is lost movement and excessive friction. Ideally all control runs should be absolutely straight whatever type they are. Shaunie.

Just a point about crimping closed loops wires (or any wire for that matter). "Squished with pliers" is not a synonym for "crimped". Sorry to bang on about it but you wouldn't believe how many think that's true. Use appropriate pliers and failure is much less likely. Shaunie. -
Coil up tightly, place in a hot open fire, observe closely until completely melted, fit a closed loop system, only have to trim the aircraft the once 😎. As you may imagine I don't like snakes as I find every time you fly the trim changes. However it's a plus one for sliding the outer down a close fitting piano wire and warming it up. The only snakes I use now is a piano wire up a snake outer or the snakes with a piano wire up the inner. I also agree that the outer should be fully supported or it will "belly out" under compression. Shaunie. Edited By Shaunie on 03/07/2016 22:40:49

I would suggest you replace the lead with more Lipo and maybe more motor. Rather than add lead why not spacer the motor further forward. Shaunie

Surely, if I the hub is excessively crushed before the bolt reaches the correct torque then there is insufficient load spreading under the head of the bolt. Either you need bigger washers or a boss plate the size of the prop boss with the same bolt pattern as the prop is drilled. This should be of sufficiently thick material not to deform as the bolts are tightened. Shaunie.

Help with problem re newly purchased ESCs and motors

Mannyroad, you read that quick, I reread my post, edited and saved, took me all of thirty seconds! Shaunie. -
Help with problem re newly purchased ESCs and motors
Shaunie replied to Mannyroad's topic in General Electric Flight Chat
I had loads of problems teaching the throttle settings on an Overlander XP2 Esc recently using DSM2. The time to establish a link was longer than the Esc was prepared to wait and it timed out. This how I got around it. I put an extension lead between the throttle channel and the Esc with the positive pin removed. I powered the Rx from a separate battery and got the link established with the throttle set to high. I then powered the Esc and got the tones, then I selected throttle low and the Esc armed. Bit of a palaver but that was the only way I could get control established before the Esc timed out. I needed the break in the lead to stop the Esc powering up from the Rx battery Shaunie.

I very much doubt if the charging current would exceed a couple of amps. The voltage drop in the cars wiring will be significant and the cable length from the socket to the battery will add additional resistance. The problem is that there are so many unknowns without a meter in series you will have no idea what the current will be. What car is it btw? Shaunie.
-
**LINK** Batteries vary but this may give you some info. Max charging current is 1.75A in this case. Cyclic charging voltage is given as up to 15V (bit much in my book) most cars typically charge at around 14.5V (unless it has a Calcium battery, in which case it is higher). The problem is controlling the charge current which causes excessive gassing if it is too high. Shaunie.
-
Yes it will charge, a bit. It also depends how flat it is and how long it has been flat for. The longer a lead acid battery has been flat the more stable the lead sulphate on the plates has become. If that battery has been flat for some weeks it could take 48 hours (or more) to charge. Always recharge immediately after use as they detest being left flat. Shaunie.

Unfortunately putting in down elevator when the ground is rapidly getting bigger is counter-intuitive to many but that of course is what needs to be done to get the wing flying again. With practice it does become a natural response though. Shaunie.

As its a four stroke, I remember reading somewhere that these can have a plastic camshaft! **LINK** There you go! Don't know if it's relevant but worth checking. Shaunie

Fail safe as far as I am aware is merely to prevent a fly away. Closing the throttle will bring the model down close to the pilot and at minimum speed. I fly Spektrum with no problems, I have had one hold in six years of flying with my gear but flying a friends plane on a DX7S I had problems, the Tx was returned and after a new RF board was fine. However the last three radio problems my club has had to my knowledge were; repeated control loss with FrSky, the pilot lost and regained control several times resulting in a head-on with the Tarmac; Control loss as a result of a flat Rx battery, good job it wasn't Spektrum or you know where the blame would have placed; finally a friend had repeated loss of model memories, Spektrum? No, Futaba. I don't believe Spektrum is perfect and it seems to have had more than its fair share of RF board problems, but and its a big but, other brands have problems too. Btw, I'm not a Spektrum user of choice but I was given a brand new DX7 and it would have been rude not to use it. Shaunie Edited By Shaunie on 13/06/2016 23:21:22

John P, as I said "dramatic over-simplification" The big difference as I see it is that with 35MHz interference causes glitching before complete control loss in most cases. With 2.4GHz the systems error checking tends to give near normal performance until total control loss, compounded by the delay before control is re-established. A few years ago I flew a camera equipped plane on 35MHz. When I revised the footage I was amazed at how many twitches and glitches there were. None of these were noticed from my viewpoint on the ground. Shaunie.

Hi john, welcome to the 2.4GHz club. Waaay back in the olden days a 35MHz receiver would respond to any transmitter signal it saw on it's frequency. With a 2.4GHz system each transmitter has a GUID (globally unique identity). This code is used to define the frequency hopping sequence for the transmitter. In the process of binding this is passed to the receiver so it also knows where to to hop to continue receiving the signal. In this way your bound receiver responds to your transmitter and no other despite the fact that loads of similar transmitters are right next to you. This is a dramatic over-simplification but is sufficient to understand the basic principles involved. Shaunie.

Sorry James, our posts crossed otherwise I would have seen your position re clubs. Yes, finding a good club can be difficult and a bit daunting, after all nobody likes to be the newbie! Of course costs are significant too. Nevertheless get some insurance, enjoy your flying and if the bug bites then take another look at the club scene, membership of a good club is something to be cherished. I speak from a position of some experience as I have spent more of my flying career out of a club than in one. I'm lucky in that I have two different fields with flying permission, one is twenty yards from my workshop where I keep my planes yet I still like to get up to the club field on a Saturday afternoon.
