These are my favorite design.
Every one pictured below is the exact same design, sharpened and epoxied.

Are there any ~$50 motors that will get my upgraded Stryker to 130+ flat & level on 4s? I'm using a MEGA 16x15x3 i think now and its just under 100 level flight.

Hi Tippy,
You wouldnt happen to have a no load data graph or file from your ICE esc for your 22-35-1.5se would you ?

How close is it to 1535kv ?

Then I will answer your prop question ............. also what "C" rating are the 3300 ??
Also, what are your elevons made of and how are they attached ??
What kind of strengthening did you do to the fuse ?
Any glass or resin ?
What are your verticals made of and how are they attached ?
Are you throwing it or bungee ?

OK, answer those and I will answer your prop question.

Haven't got to do any data logging yet. The 3300 6s is 30c-70c, going to use elevon wood stock, and going to attach them using the rite wing style with tape and adhesive, the fuse has carbon rods through it in numerous spots using gorilla glue and then covered with a bondo substance called icing, the verticals are 4mm wide wood paneling, going to use a bungee launcher, i work with brolley who is also building a stryker

Tippy and Brolley,
Both your builds are looking great!
Different construction techniques are evident in each build, and each has great elements.

Tippy,
You have an awesome motor. Look forward to hearing how it makes your bird scoot.
There'll be a lot of power going to that motor mount area. I didn't see any carbon reinforcement under that spot. I think you'd get a lot of security and performance benefit from some reinforcement in that area.
You might be able to extend the nose-to-tail carbon if it's a hollow tube by inserting a smaller tube into the current one, and making a splice joint that goes all the way to the trailing edge of the motor mount area.
Any fiberglass planned for this build? The carbon sparring you have in there now should make the bird good to 130mph. Add Mopar's epoxy coating method and I'd say good to 160mph. Above that and any bird I'd fly would have full 3/4-1oz. glass on it.
Medium-hard balsa for the trailing edge will beef up the hinge line for no worries there.
Your motor should be capable of 175mph+ level, no-wind.

Brolley,
I have to say flat out brilliant on your carbon layout!!
The steep short sections near the wingtips will help fight any twisting motion in the wing. Like it.

How fast/fun are ya shooting for?
Can you share the intended power system?
