namustang1a replied to namustang1a's topic in General Electric Flight Chat
John f.... I am aware of the veried uses of Lithium-ion cells,Lithium-ion being the type of cell not the chemical make up,lipo being one of them LiFe being another(see Lithium-ion on wiki). As for lipos if treated/cared for correctly there is no reason why they should be dangerous,i think a lot of the fires etc where possably down to lack of user info in the way to handle them when first introduced , education is a good thing but accidents happen unfortunately. Allan Bennett... LiFepo4 poly packs have been around a few years now, yes they are heavier then a lipo but then again how offten do you add nose weight to an airframe. Grant webb... LiFepo4 packs are used a lot as rx/tx power which to me is odd if you realise that the power drop off is very quick much more like a fuel tank then batteries. Thanks for the link I have seen it before, its the only one I have come a cross wilst looking into LiFepo4 safety. Ian -

Allan Bennett.. I am referring to the lifepo4 poly flight packs(looks like a lipo ),A123's are the can cells like nimh packs.**LINK** Ernie.. Swimbo is also involved in building and flying so no deception and I do like the quiet life. Ian -
I have been puzzeled to why lifepo4 flight packs are not used more and the lack of availability. I live in a smallish flat with no garden/shed and am banned(by swimbo its her flat)) from owning lipos just incase of misshaps . I do have powered gliders using a123 hard cells but thay are limited to low amh . The poly flight packs have good amh ,fast charging and can be run down to next to no volts, more life/charges and as far as I know don't self combust if a misshap happens,just brought a 4s pack from HK that ill be trying soon in a veron Cessna. Any views/comments on the subject good or bad are most welcome. Ian

From what I can recall from building a DB moth 40(cirrus moth) and modding it to look like a gypsy moth is the main difference is the cowling and front fuz up to the cockpit and the under carriage, straight axel on the cirrus and the X type on the gypsy. I built mine when I was 15 or 16 as my first scale aircraft fitted with an early os 48 surpass it even had closed loop for rudder and ele.

i was also thinking it was a inwood improver , had one years ago as my first low winger perchased as a pre built from inwoods stand at west maling show. -
sounds to me that you havent keyed up the base silver befor applying your top trim paint.use some 1200 wet and dry(maybe on a test panel first) or even a gray scotch bright pad,use both wet with a bit of soap on the paper/pad(stops clogging). Ian(ex car painter)
