Hunter

Shaun, yes I think a 2 cell will be used, I shall go take a look at this motor you have suggested, much appreciated for your help

Hi Shaun thanks for getting back to me. The finished model weight is approx 6.25 ozs, 175 grams, and the recommended prop is a GWS 7”* 5”, the original battery was a 350 mah lipo hope that helps with your recommendation cheers Mark

Hi, I was wondering if someone could suggest a brushless motor to replace a gws ips dx2 motor with 4:14:1 gearbox The model is a Peter Rake design, Plafz E1, 30” span originally powered by a IPS would appreciate your recommendations Many thanks Marl

Hi Kc, Thanks for the suggestion regarding battery location, yes I agree, placing battery in cowl on F1 below motor would be a good idea plenty of room in keep cg up front, and also agree on having battery connection behind F1 via hatch. I will get a battery either s2 or maybe s3, or both! although s2 seems ok, eithet In front of F1 or maybe behind. See how it goes! Still would like to swing a wood prop, around 9*5 in that region, and s2 seems ok, but please correct me if I’m wrong, of course I will check current draw, if a no go I will revert to electric prop. Been on balsa cabin site, and I did notice you can select grade of wood which is handy many thanks again mark

Thanks Tim, I will try balsa cabin, if they can select the right grade that be good. I built and tested Peters eindecker many years ago, and was a joy to fly, was in FSM, alas the aircraft was damaged when a ceiling collapsed! And think that put a stop to my flying until now! Just having to start from scratch! New tranny ect ect it goes on n on! cheers

Thanks Tim, I’ve noted down what you said regarding weight as far forward, obviously I will need to redesign firewall which shouldn’t be to difficult to fit motor and incorporate thrust lines ect. Will make a start on construction once I locate a good supply of balsa, found some but to soft for my needs. cheers

Thanks Kc, would it swing a wood prop?

Hi Outrunner Thanks for reply, much appreciated with your suggestions, I shall take a look at the motor you suggest and read up on there site cheers mark

Thanks PatMc, that seems a good combination, and good explanation, makes a lot of sense, just need to sort 2s battery out, let alone charger ect! Mark

Hi, Thanks for all your very interesting remarks, I shall digest all! And take note, and thanks outrunner your suggestion of motor seems just about right, Not having a computer, I can’t download motocalc or any others to test setups, so your suggestions will be on what I go on. Many thanks mark

Thanks, as I said brushless systems baffle me, so please bring on suggestions thanks mark

Hi All, It’s many many years since I built and flew ect electric powered aircraft, and with time on my side, I thought I would get back into it. But as expected, things change! Electronic and power system improved, and now I’m scratching my head trying to fathom out how to convert a speed 400 model into a brushless setup. I have a Peter rake plan from twenty years ago, of a 36” span, speed 400 motor via a graupner 2.33.1 gearbox, having built her, in her original design, which proved very successful, I would like to build her again, but convert to a brushless system. I’ve researched as best I can, asked many questions, and have been recommended the power train below Tornado Thumper V3 3536/08 1050KV SKU2979 Overlander XP2 30A Brushless ESC - RTF - SKU 2724 SKU2724 Supersport 2200mAh 3s 11.1v 35C with Deans SKU2567 APC 10x5 Thin Electric Propeller (E-LP10050E) APCLP10050E I would appreciate it, if someone could confirm that the suggested equipment would be suitable, or maybe some other combination. I look forward to your comments and input many thanks Mark
