Had some trouble with the ducts – I couldn’t get them to follow the holes properly and then I had the plastic crack. To that end I took the ducts back out for take 2. Back ducts are looking Ok (not glued yet). Had to cut a bit different to allow for my outrunner power […]
After completing the dynamic balancing on both fans using an old iPhone 3G with Vibration and following a very handy guide on RCGroups I’ve done a test run using the new packs (65C 2250mah – 146.2 amps continuous) with both motors running a mix of full throttle and half throttle: [yt]http://www.youtube.com/watch?v=rxu8RF7eAfs[/yt] Before dynamic balancing (on […]
Two sessions with the second fan yielded slightly better results than the first, locktite now in place holding everything together ready to install!
Long time no post! Been busy with other stuff. I’ve now balanced one of the two fans. Good use of an old iPhone 3G:
I meant to post these when I got them, had them for ages now – Austrian air force decals.
I performed a full throttle long run test on the twin 50mm EDF system for the Saab. Hooked up to a 2200mAh 45C pack. It lasted just under 1min 50 seconds before performance drop/empty battery at full throttle. Pulled around 65amps continuous out the pack peaking at 70 amps. Sat around 650watts most of the […]

There are 3 runs recorded, didn’t have the camera on for the very first run as I was checking for clearances. It pulls […]
Motors, esc’s and new Spektrum AR7610 assembled in the test stand while waiting for the batteries to charge before a test run. Adjusted the second throttle to run on AUX2 or channel 7. This will allow fine tuning / balancing between left and right throttle.
Test fit 50mm wemotec in the motor mount with the dons rc motors mounted. The two wemotec housings are not 100% anymore after trying to get the het motors working in them so I’m going to get some new ones before proceeding with the build.
A quick test run – got some resonance and rubbing on one housing that needs to be sorted – this is just under halfway up on the throttle: [yt]http://www.youtube.com/watch?v=T162FT90oHU[/yt]
