|Thread: WHAT size prop for a Hacker B20|
I have a Hacker B20 - 18L. 3000 rpm/V + 4.1, which I have not used for many years.
I shall be installing this in a glider. I would like to have some idea of what size prop i need using a 3S Lipo.
I have a Spektrum DX9 TX. I wish to add another servo to work from the elevator stick. I have followed this using the transmitter manual, but without success.
Any advice please.
|Thread: MDS N/V|
I purchsed an MDS 18 r/c some years ago. I recently built a Mini Super for this and it flies well.
The motor is powerfuland nicely balanced. Problem is it does not run consistently .Yesterday I noticed after starting up, fuel flowing around the N/V O ring.
Question...Is this a general problem, and is it possible to obtain a replacement?

I had a School Master powered by an OS Pet R/C. A nice looking model for its day. Flew really well too.
|Thread: gyro behaving oddly!|
Exactly my own thoughts Frank. if the worst came to the worst. Den could install an expensive servo reverser on one of the Y leads
|Thread: Radio, servo malfunction|
Doc Martin, that scenario sounds quite feasible. Friday, I ordered four new servos, different brand, different outlet.
Thanks to everybody for the feedback.
I also purchased my 5 Tower Pro servos from Bangood, I would say around one year ago. Most of these stuff is rubbish so I now longer use them
Thank you for all your help. Firstly, I hard solder all my extension leads myself using heavy duty servo wire. Also the leads are not that long. Second, the radio is 2.4 Spektrum, six years of faultless service. Thirdly the esc rating is only 2.0 amps. I checked the Individual servos which for a 13gram unit have a very high current draw of 400 mah rising to nearly an amp. It would appear as suggested this was causing the problem.
So now I know the way forward, and thank you all for you input.
I have a new small scale electric areobatic model. All set up and ready to fly about a month ago. Thursday, took it down to the patch to maiden. Switched everything on. Cheched ailerons, next thing full port rudder, and ele moving around. Unoluged te Lipo., reattchedthe lipo, and again, same responce. Put that model aside and flew another.
Back home, same thing again. Tried another rx, no good. Same with a third.
So, next thing, wrote out a second model on the Tranny. Same response.t resort. tried another tx. same problem.
Left it alone to try the following day. Same thing, as expected. Then I disconnected the two aileron servos. Normal service resumed. Next, I connected two..different brand...servos to the aileron leads....NO problem.
The servos were unused,Tower Pro, which I thing I bought from Bangood.
What i do not understand is how when operating the aileron stick, is how these poor servos can affect the other controls.
Anone have any ideas.
Am presently holidaying in Malta. Talking of Rabat, I strongly recommend that on a sunny day you lunch on the large terrace of I'l Vedura, good polite friendly service, good food, lovely pizzas for example and reasonable prices. The view from the terrace is stunning.

Laser 80. Beautiful motor.. 1st flick starts, runs beautifully, and so quiet. And looks gorgeous.
As a fellow club member remarked, a beautiful motor.
|Thread: hobbyking prices|
Me too Ken.
The low was 1.17
Dollar Sterling rate is not 1.45, and has not been at that level since the announcement of the Brexit poll. Current level is 1.31.
|Thread: DX9 problems|
I purchased my DX9 when they first hit the market.
I have never had an issue with range even wheb flying gliders at a great distance, nor have I experienced any other problems.
in short, I have been delighted with this transmitter and its many features.
|Thread: HobbyKing Why did I order from HobbyKing?????|
I must have been using Hobbyking for at least eight years. Many many dozens of orders dring that period, with faultless service.
With the exception of the new website, which is very clunky to say the least, I have nothing but praise for HobbyKing.
|Thread: DX9 Owners thread|
Just checked the alarm setting on my DX9, and it is set at 7.0 volts. Purchased mine when new on the market, so cannot remember wether or not that is the factory setting.
Have to say that with a nominal voltage of 7.4 volts, 6.6 volts seems way to low.
|Thread: Carbon spar|
Hello again dennis,
Using my dremel is what I shall do, thank you. With regard to wearing a face mask, that is something that had not crossed my mind, and shall most vertainly follow your advice.
Thank you again.
I have a 12mm carbon rod to be used as a main spar,which I need to cut this to suit. Which type of blade should I use?
