IanR Posted June 23, 2012 Share Posted June 23, 2012 Hello All Could I just add my two pennarth in regards to keeping things simple. As a newbie, I too am very confused by the often (to me anyway) meaningless jumble of numbers connected to a manufacturer's motors. I'm sure they mean something to each manufacturer but I'm beggared if I'm going to bother learning each one's specific code. I get frustrated when, on the forum, someone recommends ABC company's 1234/56 motor. It means nothing to me and, when I google the manufacturer and get a spec. breakdown, it often continues to mean nothing. Enter E-Flite, closely followed by 4Max. E-Flite have the common sense to name their motors with numbers corresponding to their 2-stroke equivelants and their website lists model weights recommended props and batteries etc. 4Max's website shows a whole list of manufacturer's motors and the Purple Power (4Max's motors) equivelants, including E-Flite. (4Max's website goes on to include a whole host of useful information and not just product specs and prices.) Bless them both for a common sense approach to a confusing aspect of our hobby.

Geoff Bradley Posted June 23, 2012 Author Share Posted June 23, 2012 I agree Ian but I'm never completely happy when the people giving the information are trying to sell to me. That's one of the reasons this forum is so good - you can ask people for their knowledge and experience which gives me more confidence in purchasing the best equipment for the task in hand.

Cyclicscooby Posted June 23, 2012 Share Posted June 23, 2012 I ignore the 2628/08 bit, and just look at Kv and watts.. Watts from weighing the plane... X per Lb... Kv depends on model size.. Most of mine, on 32"-38" models, running 8x4 - 12x6, are 1000Kv-1400Kv.. Smaller models (props) = higher Kv... and vica-versa THEN pick Esc / Lipo from motor requirements.. Simples...

IanR Posted June 23, 2012 Share Posted June 23, 2012 Not simples ! Chrisie, are you saying watts for weight and Kv for wingspan? Don't the two usually go up together, hand in hand? I say "usually" because, of course, this isn't always the case. Don't watts and kv on motors go up and down, together, also? Ian Quote Link to comment Share on other sites More sharing options...
Geoff Bradley Posted June 27, 2012 Author Share Posted June 27, 2012 I've now started a build blog and have a question for Mr Miller - I'm having trouble obtaining 'rock hard' 1/4 X 1/4 balsa for the wings from my local suppliers - will spruce be too heavy ? Also can you advise me where I can purchase a pilots head and what scale pilot did you use? thanking you in anticipation Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted June 27, 2012 Share Posted June 27, 2012 You can use spruce, it will not be very much heavier than rock hard balsa. I used about a 1/6th scale Pilot head. MD products do some quite good ones if you don't mind joining the molding and painting it. Same with Radio Active pilots. Otherwise there are a big range distributed by J.Perkins. Also you can find good ones on Ebay. Quote Link to comment Share on other sites More sharing options...
Geoff Bradley Posted June 27, 2012 Author Share Posted June 27, 2012 Spruce it is i'll have a nosey on the internet for pilots - I like the idea of moulding and painting - not done that for ages !! Thanks for the prompt reply Quote Link to comment Share on other sites More sharing options...
