"@Jacobson. the servo out of the bay is a common issue with EPO wings. reason is EPO foam has very low adhesion with most glues including epoxy. the most effective glue to mount servos with EPO is to use HOT MELT GLUE."

Very eager aeromodeller. I find UAV is the ultimate fruit of all the hard work you do while making those miniature r/c planes and the heartbreak you get when they crash.

counter rotating motor and prop set

Posted on October 24, 2011 at 10:08pm 13 Comments

this is a wonderful counter rotating BLDC motor and prop set ideally suited for planes between easystar and skywalker because of small footprint for the power equivalent 30xx size motors. it delivers 270 watts with 3S Lipo. the mounting would be bit tricky though. never tried but would order soon. very useful because prop diameter has to be restricted on pusher prop aircrafts with tail boom below the prop. once i get mine would put the performance parameters on the same blog. available at…


rotary engines for UAV

Posted on October 15, 2011 at 7:24pm 5 Comments

hi friends, on 14 October 2011 there was an exhibition organized by some 20 UAV manufactruing companies in New Delhi, India. It was wonderful to have something like this in India. The technology dispalyed was amazing. there were fixed wings and rotary winged UAV's. The show was won by this twin cylinder rotary engine designed for UAV's. The manufacturer claims to having nil vibrations in the engine. a very important issue for IMU's in the autopilot.  beautiful engine with circular cross…


Aluminum Housing for APM

Posted on September 30, 2011 at 5:30am 8 Comments

hi friends, whenever we fly in automode using APM there is always some chance of a bad crash. we do lose some expensive equipment. APM is quite expensive for almost $400 and not counting the mid night hours that go in debugging. so i have worked on a aluminum APM housing which is quite strong with 1.5mm thickness and is…

Hi Ravi. I do not know the Thomas Scherrer UHF system, but if the PWM sum is a standard 8 channel signal it should work. Just remove the propeller for safety and try and see if it works. It's not like anything will explode or anything if they aren't compatible. :)
