Many thanks Shaun. I'm starting to appreciate the differences and requirements for electric motors compared to my old nitro engines.

Hi Following some very useful advice previously from this forum, I have now completed the building of a Gentle Lady sail plane as my first entrance into electric powered model planes. I have searched the many forums on suggestions for the right motor/ battery/ESC combos and have to confess am more confused particularly with some of the USA suggestions. So this is where I am today. I am looking at the 4Max PO-2826-1046 motor with its 1040 Kv with a 30A ESC using either a 9x7 or 10x6 folding prop but not sure about battery. Would a 3S-1500mAh suffice or do I need something bigger? I can see cooling may be a problem as everything is enclosed in a small space. Any help or suggestions appreciated. Plane has come in at 22ozs with its 6ft wing span as spec'd.

Many thanks gents for all your comments. I believe I need to have a rethink on the conversion judging from your comments and just finish it as a free flight model with existing nitro engines if necessary. But I also bought as a job lot a few kits that hadn't been built as yet. They include: 1.Goldberg Models Gentle Lady 2 ch sailplane 2. Ben Buckle Taylorcraft 0.57 Would either be suitable as an entry level in electric powered R/C? .

Hello I have recently returned to model making and flying after 30-40 years absence. I am now attempting to convert a Guillow’s Cessna 172 to R/C control using an electric motor. I have a Futaba 4ch 4YF and some old servos but have invested in some Ripmax micro SD200’s. The 4.8V 700mAh battery pack looks a bit heavy. So I looking for recommendations of a good brushless motor and I read a lot about LiPo batteries. Does anyone have some suggestions? Also If the motor was to be more powerful than needed that’s OK as I am moving onto to some bigger kits next!
