Here are some remaining pics from the test flight day. I like the landing pic but I'm sure it would haved looked ten times better had Jon Barnes been there. Maybe next time...

Sounds like you might have to give kudos to the missus if you have all that play time...

I'm working on fitting the tail controls at the moment. A little tricky with anhedral elevators. I have it sorted and epoxied the first one(control rod) on last night. Bent the other control rod before I ran out of time for the evening. I got the servo to lie flat under the tail pipe (by cutting it into the bottom of the center piece) and arms to the side so it's all hidden inside. I'll post a photo when the other rod is epoxied on.

The closer this thing gets to finishing - the more it feels like a 40mm jet.... Hope the RPG comes through and scoots this thing along.

Nice photo's pdawg.

Thats good to know! CN's 40mm powered Electrolyte had significantly improved acceleration on launch compared to the original 30mm powered prototype. My next one will definitely have a 40mm fan in it cause I'm having a hard time saving a significant amount of weight in the airframe. Tres made a nice chart comparing different 12mm inrunners. The 5800 kv inrunner and a 40mm GWS fan looks like a good starting point. It will use the same lipos as the 30mm fans so no additional weight but hopefully more thrust. That should make the launch easier!!!

If trying to save weight, try a carbon disser pattern and light glass or aramid lay-up on the wing instead of the balss sheeting. It's light and strong enough for DLG's; it should work for this, too.

Also, Neu has a "upgraded" version of the Medusa 12mm motors available now. 2mm shaft, bigger bearings, etc.

i got my rhino 30C 1050 2s packs in....they arnt much bigger than the 750's i had before....and i got the turnigy 18A esc. just barely fits......both these improvements(and the ability to run full timing without fear of blowing the esc(only using a 10A before...on 4s.....with 3 servos.... had one blow when i tried full timing....) ill have that soldered and test ran tonight........i think with these changes, i should be able to atleast get to 95mph. smoother passes will really help too....you cant see it in the vids, but i was fighting the ailerons back and forth, resulting in sloppy speed runs. the servos dont like to center well....

I test fitted a HK Nanotech 1000mah 4S lipo last night. It fits.

The decision has been made to go 40mm EDF after discussions with pdawg. I'm going to mount the 8 blader I have here.

Great decision I'm sure since the testing so far showed the 40mm to really shine!

Things I did today with the Electrolyte build

I cut the inlet ring away from the 40mm case which unfortunately let the case warp just enough to cause rubbing on one spot, so a patient sanding to the rotor tips to get it clear was done. Once that was sorted, I tidied up the rim of burs.


I made a quick and dirty plug for the duct tube using an old plastic hair products bottle, some 1mm balsa, some masking tape and a bit of plaster of paris.

I filled the bottle with plaster to hold it's cylindrical shape. Once I had the balsa shaped the way I needed it (the 1mm sheet brings the diameter to the same as the case and the next 1mm ring supplies the lip to slide over the intake ducts and fan case), glued around the bottle but not to it, I put a 'funny balloon' over it to act as the release and glassed it up. When it dries, I can remove the bottle, collapse the balsa and I'll be left with the tube ready for trimming. It took a very short time to make it.
