Martin Westquay's Piper Cub ;-)

Hi Martin, thought you might have gone electric with the Cub. I recently made a repro of my 1975 48" Graupner PA18 Super Cub, and used a 28mm 1200kv brushless motor with a 3s 2200Mah LiPo. It has more power than you need by a country mile and is very quiet. Takes off with around 1/4 throttle. This TGY motor is one of the most powerful I have found for its' size, and I had one of the HK Cosmic Wind crappy 900mm glass models up to 91 mph with 2 x 2s 1800Mah 20c batteries strapped together (these motors take a 3s-4s)- 40c batts would have had it over the ton. Problem was, being yellow (the worst colour I've found for visibility on a sunny day) and being so small and fast, I actually lost it for a few secs while going vertical at high speed (sort of blended into the sky)! You don't need a huge electric to pull a model, roughly need one which will handle the same sized prop as the model would normally use with an IC motor, and pull the same max revs. The beauty of electrics is the lack of mess, damaged fingers, starting frustration, expensive and noise, plus your plane will last longer not having oil all over it constantly (and because it has no smell your missus might let you bring it in the house!)😂. Depending on your finished weight, a motor of this nature might be all you need ( or a lower power 35 Diam motor). Just a thought. John B
