Hobby King Waco SRE


I just purchased this 1/8th scale model, and wanted to start a thread on it. Has anyone else got one of these? If so, please put up any helpful hints, motor suggestions, etc here. ------Metalguy

Went and looked myself. That thing's gorgeous! 51" wingspan, it's nearly as big as my 56" Sterling.



I'm gonna need one of those.

I just hope she flies as good as she looks. It is a looker, for sure. -------Metalguy

Make sure you have a ball driver. The cowl mounts through a ring epoxied to the back of the cowl. As such, there are no exposed fasteners. Kind of a pain to get to, but worth it with the cleaner look.

I've flown with the interplane strut mounts un-glued, which means you can break the model down in about a minute. The wing panels are held in with rubber bands internally. (Hooks at the wing roots)

I used 4S 2600mah Lipos, but it has the space to take a 3000 no problem, and the extra weight will be no problem as she comes in plenty slowly as it is.

3648 850 kv is what I used....they have a typo on the website. The motor I used was same as the Avios Yak 52, just the higher KV motor. I know this, as it was the motor I was originally using on the Yak 52 prototypes, but the current was higher than I wanted on the scale prop. (Hence why the Y52 now includes the 680kv)

Since that was a random sample..... I would probably use something like this: https://www.hobbyking.com/hobbyking/s...ner_Motor.html

Could probably use this one too:
https://www.hobbyking.com/hobbyking/s...ner_Motor.html

I've got one more of these I haven't built yet, I'll start building it shortly and post up some of the tips I found. (And the CG I used, since I'm not sure what they did for a manual after I left HK)

I'll look tonight. I keep forgetting to check the measurement. For some reason, 65mm back from the top wing leading edge is sticking in my head, but wait until I confirm.

Thanks for the info Paul, let us know when you start the build of your second Waco. I'm working on a materials list in order to complete mine, and get her in the air.
