Slow Stick - My First Build -- Insights Please

Hello Everyone

I just joined the forum...and am returning to model aeronautics since flying control line planes (and building balsa wood models) back in the 60s. Having to learn a lot (electronics, etc.), but love the idea of scratch building my first plane. While wondering what to build, I came across Flite Test...then came across Rahul Satur's build of the Slow Stick (May 26, 2014).
Decided to go for it; love the little plane since it's quick to build, inexpensive, and I just want to do it.

Here's where I need some insight.

He list's the following for a power system:

1) 2826 1900 KV brushless motor
2) 8 x 3.8 Slow flyer prop
3) 20 amps ESC
4) 9 gram servos x 3
5) 2S 1000 Mah Lipo

So, I ran over to Hobby King and looked these parts to order:

1. Turnigy Aerodrive SK3 2826-980 KV brushless motor
2. TGY Slow Fly Prop 8*3.8SF w/shaft adapters
3. HobbyKing 20A Blue Series Brushless Speed Controller
4. Turnigy TG9e 9g/1.5kg/0.10sec servos (3 of them)
5. Turnigy 1000mAh 2S 20C Lipo battery

Question 1. Is what I want to order, correct for what is suggested?

Question 2. If they are, do you have any suggestions for other vendors that would have these items, or comparable? (Hobby King notes that several of these items are backordered; I have no idea when they'll be received by be since I would have to get them from their International warehouse).

I haven't pulled the trigger on the Hobby King order yet; their site has been real hinky lately and I thought to ask around.

Would love your insights.

Thanks so much. Glad I found this forum.

Welcome to the forum Reggie!

Not sure how to put this, but the recommended motor has a kv rating of 1900, the motor you have in mind has a 980kv rating. With the recommended 1900kv motor you will get 14,060 revolutions per minute, with the motor you have listed you will get 7,252rpm. You will get around half the thrust you need for good performance with the motor you have in mind.

Hey Reggie, Welcome to the forum!

um . . . almost.

The motor you've selected is 900kv, not 1900kv. That ends up having less than 1/2 the RPM on the same voltage -- not so good for that prop. You could either get a longer prop or a faster motor. This guy is a bit faster, but should handle the 8x3.8 prop on 2S.

Otherwise, the rest seems just fine.

Try Headsup rc located in Florida.

I use their stuff all the time!
I copied you requirements and compiled a list of their in stock componets and they have it all! Their shipping is just $2.00
Yes the componets might be a couple a bucks more but when you compare HK's shipping and out of stock it is a wash!
AND the ESC comes pre wired and so does the motor no extra parts need to get up and running!

Well....Missed that little detail about the motor :eek:

Thanks everyone for your replies; makes me glad I found this forum. I think this will be a great place for shortening my learning curve.

Vipertech...thanks especially for the links. I was born in Ocala; know exactly where Ocklawaha (Headsuprc's headquarters) is! I think a field trip is in order (I live in Ana Maria Island, Fla)!!!!

Thanks everyone; will keep you posted on my build.
