Just re read the article and the guy,s name is peterangus (sign in name) not fish. Also just would like to clarify what i am trying to find out which is. If you load a brushless motor at full throttle to say the max amps for the  20 -30 secs rate which often quoted by the manufacturer this may be a max power situation for that motor but it would be a low efficiency.Now  Peterangus says( I hope I am quoting him correctly) that the low efficiency would remain at lower throttle settings? To further quote him he says Propping to 50% of no load rpm is overpropped max power but low efficiency and 80% no load rpm is underpropped gives max efficiency but low power.He calls this speed ratio. Does anyone know if the full throttle efficiency level set by the motor prop combination at fuull throttle remains at lower throttle settings?

Hi all, can someone help me clear up this question about motor efficiency which is.Recently I read a thread on Giant Cod site Placed by a chap who signs in as Fish. The thread was called dont overprop dont under prop. In his write he talks about loading a motor to around 70%of its kv x volts theoretical rpm.The main thing was that it sounds as though the loading and resulting efficiency will remain even at lower throttle settings{perhaps due to the chop current priciple of the esc. ie current remains the sameall be it in short pulses} My method has always been to prop the motor {at full throttle}to the max efficiency current or more important to this topic the max current for short burst like 20 secs.If the foregoing is correct doing this you will not get a good power efficiency compromise. Hope I have explained this correctly and that one of you kind people out there can put me right on this matter. cheers Ian.

I have found this site to be by far the best. Its abit like being in a club atmosphere with product review on all items.There is no sign of sales pressure at all. and as though Rob tends to let you make up your own mind.And then there is his prices and service which is nothing less than excellent every time.

first time i have used this site and it will be the last.Infact I didnt use  them i cancelled the order. got a phone call from them and  out of the three orders i wanted they didnt have any of them.Two items were ordered as packs of ten they only had in packs of two by some other supplier at a greatly increased price. The other item was some other make which may or may not have been ok.The last item was only added because they will not accept online payments by card under £10.Also the site is not secure and you have to trust them to how they want to charge for post and packing as its not shown when you leave your card details and click on pay. In all for a model site of this size I think its a very poor show and I will get by very well without them.
