have you decided what prop you are putting on that setup?

the way i calculate pitch spees is: (volts X motorkv) / 60 then x prop pitch then / 12 = feet per second, (which is also within 10% of kph. )

so in this case 4s= 14.4v x 1900kv =27360rpm, / 60 = 456 turns per second, x pitch of prop, say 5inch = 2280 inches per second / 12 = 190 feet per second = 129mph. this is pitch speed though so you might not get 100% efficiency and only see, i dunno maybe 120mph?

so if you are keen on getting airspeed of 130mph+ you might need another cell. not sure though. ck might be able to tell you exactly what speed you can expect though

hope the build is going well!

It's come to a halt waiting on the CF rods but I have them now and will start to build tonight.

I believe CK wants me to start off with a 6x4 just to get used to flying it and then work up to a 7x5 / 7x6. Only time will tell =)

Just my thoughts.
I should have enough room to PU the bottom up good and sink my lipos in close to the bottom without actually hitting the glass. I hope to resume building tonight and get another video done this week.

I picked up a new 36" Lightning from Chris last week. I cut the bays all the way through and then countersunk coro in the bottom of the bays as I described. It makes a really nice finish as opposed to the ragged looking bottoms of my previous builds. Also, even if I go to a bigger battery I know I'm getting the maximum depth (minus 2mm) in the bays.

Sweet, I can't wait to see it!

Progress is slow lately but moving a head.

I also have a sweet finishing technique that I'm working on to get a smooth surface for painting. Should be pretty light but I'll share that once I confirm that it works well.

Sorry about the absence lately but I've been tied up at work and still moving into a new home so things have come to a halt.

I should be finished moving this weekend and resume my build later on next week.

Pnot you have the microdan 2510 2700 right? do you think it would be a good choice on a lite demon? have you got any data from personal use on a demon?

I think the Demon is too big for that motor. I have one on a 36 lightning and running 3s and 4s 2600's. I messed up the motor though. It ran great for about 8 battery cycles and then just quit. It does the stuttering thing but no go. The good thing is Dan can probably fix it. I'd look for something in the 2000-2400Kv range. Those are my thoughts from my experience.

I just moved again and am setting up the hobby room with all of my equipment. It's turned out to be quite an undertaking LOL.

Why not stick with what works for the Demons like a mega or rocket? Is there something about those combos that your worried about or just wanting to try something new?
