Hello Everyone,
Thinking of building a Vic Smeed Tom Thumb that calls for about Cox 0.10 . However want to make use of PKZ 3616 the E-20 standard motor with a  single cell . So would these be equivalent ?

My Tom Thumb flew well on that motor a few years back. Build it light though.

Thanks Bill. Appreciate the confirmation. What Prop did you use on the PKZ 3616? Will try and stay around an ounce or so. The PKZ motor handles my E20 at an ounce very well.

My Tom Thumb flies well on a David Banks Bambi. It should be quite lively on a Cox .010. Beware they become very small vey quickly and small motors run a long time on very small amounts of fuel.

Hi Ricky, thanks for sharing your experience with the Thumb. I am trying to go electric with the now famous E20 motor with the E20 prop. As Bill has already confirmed his experience with the PKZ motor, I am looking forward to this winter build.

My question now is : What is the max prop the PKZ motor can handle onn 1S lipo without getting fried.

Are you flying it on a gear box or direct drive? Bear in mind that the E20's fly DD which gives less over all thrust.

The geared PKZ will give you about 30g of thrust which should be about right if you build to the target weight of 2 oz (57g)

Micron RC have useful figures and prop suggestions here:

I'm flew mine with the gearbox and the P-51 prop.

A guy here in NM flies a One Nite 28 on the same setup! Not a screaming climb but it flies.

PS: Also flew it with the old Air Hogs compressed air setup. Didn't do as well as you might expect.

There are upgrades for the PKZ motor if you want a bit more power.
The Micron site shows the CL-0820-15-9T and CL-0820-17-9T which fit the same gearbox. These should be fairly easy to source because they are used in micro quadcopters.

Thank you all. I am still building it. But am planning ahead for the electric power. Will go with the geared drive to get the 30 gram thrust. Trying my best to stay at or below 60 gram weight (2 Oz?). Planning to use Lemon Rx for power and Servo DT. Small servo (1.8 grams)
Thanks again.
