With any wheel it's the legs that count. The units just move them! Axle sizes and type, but being Metric you would expect them to be compatable if they both use the industry standard 6mm

Airtech offer electric brakes.

Just put my order in for 2 sets of the 85mm wheels only
Strange web site - order was placed and email confirmation sent but they didn't ask for any c-card details ? maybe that comes later when they are ready

OK folks, fix'n to embark on my Ultra Flash build, plane arrives at end of March. Black/Yellow Eagle scheme, JetCat P140rxi, JR8411 all around, Pro-Link electric gear combo-pro, adding a wing tank, no smoke. I'm looking for tips/tricks, ideas, and nuggets of knowledge to make the build progress smoothly. This is my 2nd Flash, had the classic, didn't build that one, fried motor, sold plane, wanted an Ultra all along. What size RX battery fits in those little side slots next to nose gear?
I'm sure it's all been posted before, I've read about 50 pages of posts, that's testament to this plane's popularity. Thank you all in advance.

Fuse.
Check the rear face opening .it generally needs making larger, it needs to come within 3/16" of the fuse top.

Clean off the tailplane seat area of all seems before you start.

Nose opening will need opening to match nose door-there are thin scribed lines on the door approx 2" apart. Wheel rectangle will probably need lengthening.

When you do the tailpipe-carbon bellmouth joint, the steel tube can only go into the carbon around 3/8" (just enough to get the fixing screws/rivets in)

Don't use the supplied Tillitson clunks with the 140Rxi unless you open up the central hole-but do use a felt clunk 100% in the fuse tank-I do in the wing tank too, but you could use a weighted clunk with conical rear edge.

Wings are straight forward just your gear choice fitting.

Tailplane the same, the aluminium brackets may have you scratch your head a little, but they work out fine.

Enjoy the best sports jet yet...

thank you for the battery ideas! In the Classic, I had 2 Lipos taped together, and secured in nose compartment with velcro, major PITA to take out and put in, many slices into my hand!

Mr. Dave!

Thank you for you time and input. Yup, wings and tailplane easy/peasy. Just want to make the misc goodies installed into fuselage as tiday as possible. The Classic flew great! I'm sure when I get my hands into the build, I'll have more ???'s

The type I use is not available in the US. If you know someone with a lathe the stock inner supplied drill out with a 0.11" (2.8mm) works great

This is what I do except drilling the main inner. Helps keep the suction vacuum lower.

Yes, they can, but we supply a felt from a different source.
