Erfolg Posted March 20 Share Posted March 20 I have an electric motor a Tornado A3615, unfortunately some of the whole important data I would like, I do not have. What I am seeking is the max amps/watts, ideally related to 3s Lipo, will it run on 4s. Useful information relating to propeller information/selection? I am pretty certain that this was a Overlander, stocked item in the distant oast. Quote Link to comment Share on other sites More sharing options...
Dickw Posted March 20 Share Posted March 20 Is it this one? Any other information you can give? e.g. can dimensions, weight, any text printed on it? Dick Quote Link to comment Share on other sites More sharing options...
Erfolg Posted March 20 Author Share Posted March 20 Yep, Dickw, just lacking the info I seek. Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted March 20 Share Posted March 20 If it's an Overlander motor then they should be able to provide all the necessary details, even for their discontinued products. https://www.overlander.co.uk/contact/ 1 Quote Link to comment Share on other sites More sharing options...
Dickw Posted March 20 Share Posted March 20 As leccyflyer says, contacting Overlander would be a good idea. Failing that, a set of scales would give you the weight and then you could safely operate it at the good old rule of thumb of 3 watts per gm of weight. Looking at similar types of motor my guess is that it would weigh a bit over 100gms so you could run it at 300 to 400 watts. It appears to be 1600kv so would want to run at about 13,000 to 14,000 rpm on 3s - say an 8x6 or 9x6 prop. No guarantees of course, but that is where I would start in the absence of anything available from Overlander. Dick 1 Quote Link to comment Share on other sites More sharing options...

PatMc Posted March 20 Share Posted March 20 (edited) I have a pair of them, I believe they are actually re-badged Himax 3615/1600 Link gives some useful data but I think pre-dates general lipo usage. Used one of mine in an old Protech Unlimited (hot liner with plastic fuselage) on 3s with an Graupner 8x4.5 prop which gave about the same power as an Olly Tiger diesel. Great little model 🖕 Edited March 20 by PatMc Quote Link to comment Share on other sites More sharing options...
