Wasp With Pjs300

Heres a photo of my Wasp so far.
Plan to use that 300 laying next to it.
4th of July is coming up so I got a little patriotic.
Plan on using clear covering. Hope the paint did not add to much weight but with the 300 I should have plenty of power. If not I plan to use a dual IPS.
Will keep you posted

Love the patriotisim! Your wasp will not be under powered with the PJS 300! It's far and above more power then a Dual IPS. I upgraded to the D-IPS on my Wasp and it helped but it flew very well with the IPS DXA. My avitar is of my Wasp flying inverted with the original IPS. Yours will be more like Tres' with the geared 010!
Have fun and don't forget to post more photos and videos if you can.

Yes, it will require a prop to fly. There are a couple of options. One is to use a prop adapter. Can't give you any details on this since I didn't go this way.

The second option is to attach something to the drive shaft to act as a prop saver, then rubber-band the prop to the prop saver. This is what I did. Most people going this option use a popsicle stick to make the prop saver, but I modified one of the GWS prop savers and think it is the best way to go.

What prop and batter will you use?

Hey 10Thumbs

I have a prop adapter that will fit the 4mm shaft.
The only problem is finding a prop that will fit the adapter.

As far as batteries goes. Good question. I will start with a 9x6 prop and a 2 cell or 3 cell 1200 lipoly

I will take any advice

Well I ran the 3s 1200 pack with a 9x6 prop.
Started with 8 amps or so at WOT.

Held it in front a big fan and ran it at about 1/2 throttle for about a minute. It was getting hot. I used nylon tubing for my motor mount and it started to soften it up some.

Less prop/Less batteries.

Thinking about just putting a Geared Astro 10 or a Dual IPS that I have laying around and save the 300 for another project.

Three Lipos are too much for the PJS300. Can you try only 2 cells in series? That might impress you

What Mike said,try two 1200s and a 10x6 GWS HD prop.If you don't have the 2 cell packs,you could try a 9x5 HD prop with 3 cells.

Yeah, I concur, you'll probably be pleased with the performance of a 2-cell pack and that motor to start.

Larry, the GWS 10x6 Hyper Drive prop has a 4mm shaft hole. Some people have said it's the best performing prop they've tried on a PJS-300. Unfortunately, the 9x5 and 8x4 HD props inexplicably have 5mm shaft holes instead of 4mm.

As other have noted, those running the 10x6 HD were only using a pair of LiPos, not a 3-cell pack. Also, I don't think that the PJS-300 is designed to be run at >6A, so you should be very careful with that 8A setup.
