Phone George at 4-Max

He will give you the best possible combination of motor, ESC and prop.

You won't want much power for this model! My Sig Seniorita was fitted with an Enya 30 two stroke ( a very powerful 30 ) and it was a real handful on takeoff at full throttle on it's first flight - far too much power. Flew OK on about quarter throttle though.

So for electric maybe 50 watt per pound may be about right - same as a vintage model. I must re-engine this model sometime after 25 years of storage - and i will probably use a 250 watt electric motor as it's very lightly built so the weight is around 4 to 5 pound I think.

You might not need to phone 4Max ......

if you look at this list and scroll down far enough you will find Graupner Elektro Kadett and a suggested motor for this model which I reckon is the same. or very similar. There appears to be a slight misprint on prop size -should be 10x 7 for a 3S lipo I think.

My own Sig Seniorita is 3.75 pounds according to my notes so 250 watts will be my choice. However my model is built very lightly with a very light covering material. The wing is huge and could end up very heavy if the covering is heavy, same for tailplane & fin. Could easily end up 5 pounds or more if covered with Solartex & paint etc. Also the Lipo would need to go well forward to avoid further weight of lead to balance. Although the Seniorita is a relaxing model to fly it is not very challenging for an experienced pilot. Good as a first model and easy to see in the air but it won't help progress. It may also be good for getting back into flying though. Many people would say the Super 60 is a better plane for progressing with flying and as a general hack if built as 4 channel. The kit is cheaper than the Seniorita and anyway a plan can be downloaded free from Outerzone.
