Let me guess. After unloading this lot, he realised he'd left his tranny at home.
|Thread: Phoenix - trim for beginner planes|
Happy building and flying.
Speaking from bitter experience I would not worry too much at this stage about landings. The real advantage of flying using a sim is to get the feel of the model in the air, and to begin to get the brain to think for itself when you are flying, just like you do with a car when changing gear. It takes time for the brain to learn this automatic control.
Pheonix has one major difference from flying a real model, and that is seeing your model from a distance as it approaches the landing zone. On the sim your approach has to be a lot closer because the model shimmers on the display (I'm using a high quality 22" display with a fast computer). You have much more time in reality, and can slow the plane down gently allowing it to drop slowly, and at the same time adding a little up elevator to compensate as it slows.
If you are joining a club, then they will no doubt be able to use a buddy lead system, and this will mean for the first few flights you do not have to worry about take-offs or landings. Once your experience develops (and this brain/hand co-ordination) you will be able to make your own take-offs and landings with someone there to quickly take over should things go wrong.
|Thread: Proxxon TG 250/E Disc Sander any good|
Are there any comparable sanders? Most available are full size jobbies which would demolish a sheet of 1/4 ply in the blink of an eye.

|Thread: Phoenix - trim for beginner planes|
I needed a lot of up elevator on the high wing trainer on the Phoenix to get it to fly level at half throttle, I don't think its your setup at fault. Even on full throttle it still needed some up elevator trim. If you go into the model setup and change the thrust to weight ratio from 0.8 to 1.2 you will find it will fly on about 2/3 throttle with no trim. Also it will then better match the flying characteristics of the E-Pioneer with a 4 cell (4S) battery. You will also get an appreciation of the difference between flying the E-Pioneer on a 3S battery and a 4S battery.
Incidentally, the actual E-Pioneer with a 4 cell battery should not need any elevator trim at half throttle when running on a 4S battery.

|Thread: New site appearance|
People said that computers would ruin your eyes when I first started using them regularly 35 years ago. My eyesight is fine now, and I don't believe the 10" tablet I'm using now will do them any harm now.
On my Android tablet, if I touch an area where the tablet cannot recognise which part I am touching, a small window enlarges that part of the page so I don't need baby sized fingers to operate it.

I don't understand why you do a failsafe check after attaching the propellor. This can be quite happily done before. The few seconds a motor might run at full speed with no prop on should not damage the motor.
|Thread: Cutting big holes in balsa|
Just how much weight do you save this way, and are there any better weight saving options. Eg, smaller more powerful servos, shorter servo leads, lighter wheels etc.
|Thread: Nasty incident|
Its obvious really, you just simply remove the safety plug.
Hmmm. Not sure about that. Drove a car not long ago where the steering wheel was at the passenger side, there was no clutch pedal, and the handbrake was operated with the left foot.
... and another test for quadcopters.
I have a DX8, and no I did not reverse the throttle. Yes I always check the failsafe as one of the final setting up checks.
Peter, I'm pretty sure I've had the same problem when setting up too, though I cannot remember how. My Spektrum has the throttle set the right way round for the ESC, but there is a fairly complicated sequence for setting up, and I ended up with the failsafe set on full motor. However, as there was no prop on and I was actually checking to see if the failsafe was set correctly, it was easily corrected.
I do notice how few flyers really understand electric, and certainly never set up their ESC correctly for the model. Most clubs seem to have a wealth of experience about ic gained by many years of usage. However, in depth knowledge or understanding of electric is far less. In Erfolg's all electric club, I suspect things are different, with a far better general understanding of electric.
A few months ago there was a storm of protest when I said that electric could be made safer (note the "could be" than ic, though obviously as you point out it can never be totally safe. One irate respondant, a long term instructor said he found electric less than satisfactory, and had a bad experience of a trainer cutting out completely in the air. I asked him if the ESC had been set correctly.The response was all to typical. He did not know about programming the ESC, and had not checked that the learner has set anything up. I bet that same instructor would have gone over an ic installation with a fine-tooth comb before flying the model.
There's a fairly comprehensive sequence for setting up an electric plane in July's RCME, which covers setting up and checking the failsafe.
I will repeat again, if you fit a safety plug correctly wired in to electric models then the model simply cannot start without warning even with a battery connected. I take my plane onto the flying field, switch on the transmitter, stand astride the model behind the wings, insert the safety plug with the transmitter on the ground, stand back and then go through the pre-flight checks.
On landing, I remove the safety plug in the same manner and carry the model, now completely safe off the flying field.
All my models have a safety plug, and once that is inserted, it sends a clear mental message that the plane is armed.
Not if you fit a safety plug.
The other thing I would do is fit a safety plug to your model. This provides an extra level of safety protection. I always stand astride the fuselage to bend down to insert and remove the safety plug.

Electric or i.c.?
|Thread: My Jitterbug flies superbly|
My desktop has crunched, so the piccies will have to wait until I can repair it. Think I will need a new motherboard for it.

|Thread: Giant Shark are Back|
I'm not happy with my last order from GS. Bought another lipo charger and asked of 1st class delivery, but not signed for. The charger arrived last Friday and had clearly been opened previously. There was an opened empty plastic bag in the box under the charger, and the lead to connect the charger to a battery was missing. I emailed GS on Friday night, and got a response on Tuesday, basically saying this could not have happened. New lead was sent but sent first class signed for. As always happens I was out and had a 12 mile round trip to collect it.
Annoyed firstly at getting an opened package with bits taken out, presumably hoping I wouldn't complain, and secondly why sent a small inexpensive lead by signed for delivery? I could have made a lead up for less than the petrol cost to collect it.
