Fuse wire as used in the old type fuse boxes is an old favourite. Still available from lots of ebay sellers.

Put a smile on my face!

Many years ago I helped run a folk club in Twickenham. One evening Rick Wakeman turned up as an ordinary punter,he was very unassuming and made no attempt to draw attention to himself. That impressed me, seemed like a nice bloke.

The thin plastic bags that jackets/suits etc come back from the dry cleaners in

I had exactly the same thing happen to a Waypoint 2 series motor a few years ago. I ran a few tests on it then put it away pending a suitable project. It was stored indoors in a warm dry location but when I got it out some time later it was stiff and the magnets looked just like your motor. In my case I just binned it. I also have a 3 series Waypoint motor from the same era and that is still fine.

You are no more than 30 mins drive from the Surrey Radio Control Club near Faygate. Nice flying site at a very pleasant location.

Thanks for the link

I agree with Keith, a fully charged cell is around 4.2V so a three cell pack will be around 12,6V immediately after charging but this will quickly drop back to the sort of level you are seeing. I would check what the individual cells read on your tester to make sure they are reasonably well balanced.

I've got a Riot on 2.4GHz but I can't see any reason why 35MHz would be a problem, especially bearing in mind it uses a brushless motor. Obviously do an aerial down range check with the motor running.

I have been using UHU Por on my indoor models for several years and am now beginning to see a problem. Over a period of years it starts to turn brown and become brittle.

Might be worth contacting Ripmax

My standard size Riot had similar characteristics, fixed by adding some downthrust.

I'm with Gary's analysis 100%. The higher the capacity of a LiPo the longer it will take the charger to get a pack back in balance and periodic re-balancing on a stand alone balancer is good practice. One other thought, with the Imax B6 type chargers the default mode when selecting LiPo is not balance mode. If I remember correctly you have to press the + key once to get to the balance charge mode so it is just possible the original poster was not actually in balance mode.

The Imax B6 and most other balance chargers work by applying a resistive load across any cells which are higher than the lowest one. The effect of this is to reduce the charging current in the high cells by around 200mA. Depending on the degree of out of balance the pack may or may not end up fully balanced by the end of charge. For badly out of balance packs connecting them to a stand alone balancer is good practice. To say balance chargers do not balance the pack is simply incorrect.

I have seen this on several occasions, it only seems to happen on older packs and I am fairly sure it is the charger having difficulty in accurately balancing the pack. When this happens I manually stop the charger then check the cell voltages, provided the balance is reasonable I use them as normal and without any problems.

Take a look at PicaSim, although biased towards gliders there are quite a few power models and the flight dynamics are very good in my opinion. Available on PC and mobile platforms the best bit is that it is free with optional donation (which I did).

I'm still using the original bolts that came with the kit, I wanted some spares just in case of loss or breakage.
