First run of my motor with little problems, I think:

Sounds like misfire, which gasoline do you use? 
Jajaja. I was thinking the same.
It would be nice to check first with another remote , just in case it is not just the throttle signal

Is that the Yamaha clone propeller, 7.5 X 7 or 8 pitch?
Yes. 7 1/2 x 7 - BA propeller
Thanks. Think that one is one of the better of “standard propellers”. By the way nice project and nice hand crafting!

Hey Pablo,
nice build!
Did you just wet layup the board with CF or have you vacuumed it?
Can you describe the process of putting the CF on the board you’ve used?
How many layers and which weight of CF?
Thanks
I used vacuum very ligth 30-40% because you dont want to crush your foam (make test with your pump). This is just to guarantee layers stick well in the foam.
I used 1 layer of 3k 2x2 Twill Carbon Fiber 200gsm and 1 layer of fiber glass 160gsm (2x2 twill). I made the arrangment of both layers along the top surface and then applied epoxy resin with roller. Then I covered with peel ply, release film and breather and finally applied vacuum. The same process to the bottom surface. So one day the top surface, other day the bottom surface. Dont forget use masking tape to limit the extension of layers. Need a lot of patience.

Did you put glass on top of CF or on the bottom - on the foam?
How did you manage not to get folds on fabric when vacuuming?
After taking the peel ply off what did you use to get shiny surface?
I put fiber glass at top of the carbon fiber. This way you protect Carbon fiber from sanding. When sanding also try to not scratch the glass fiber.
Actually I have some fold. I try to put peel ply in position (as an additional layer with resin). vacuum must be light at beginning in order to accommodate the bag.
After taking the peel ply, I apply thick resin, Then I sand. Then again thick resin and sand. Again resin and sand…Until you see a uniform surface. Always take care dont scratch or minimum scratch the fiber glass. Finally apply a clear epoxy top coat (dont need to be thick or the minimum recommended for provider).

This is also a good/simple option for inserts.

Sounds like an ESC problem. Which one are you using? I’m building with Maytech 65162 motor also.
I use ESC Kedean 200A. Peak 560A
Problem was solved. Was the transmitter. I tried with another and here the result:

I’m really curious about the performance of your built. I bought the same propeller, but I’m also planning to print and test a whole bunch of other propellers.

What did you put as an intermediate layer on your engine and carbon fiber to avoid galvanic corrosion over time?
Mmmm. Interesting I didnt consider that! Putting a layer of fiber glass with resin in internal diameter of cover as insulation could solve this problem. I understand now why fiber glass is located as final coat on board. Nice
Minute 6:00 you could see the answer.

Hi.
I don’t have any experience with those. But, I have experienced the frustration of when a threaded insert fails and spins in place.
The type of insert I linked has a large flange that is laminated in the resin and more resistant to breaking loose.
My fear with these inserts is that they will spin if the bolt is over tightened, or with corrosion. They don’t look reverse threaded, so they might break loose and screw out along with a stuck bolt.
Let me know if you guys have any first hand experience with them. They look good for a easily replaceable part, but maybe not for lamination in a board.
Horses for courses I guess, depends on what route you take with your build. I’m not sure how you would adapt them into a piece of Aluminium or CF.
I see your point with them possibly threading out, however with how much I had to swing on a 13mm spanner to get them set in place I would be very surprised if they were to thread them selves out, could alway put some epoxy down the hole before inserting also.
