Thread: New EDF Mini Jets- Jet Provost & Folland Gnat
04/12/2019 13:03:44

I initially only glued the motor in with a few blobs of hot glue and it broke loose after a hard landing. I have now glued it in more comprehensively.

Also finished mine, nice build, but first flight was hairy (tail heavy). Have added 70g in nose, and waiting for right conditions for second flight.

Went Saturday, weather fine apart from showers lunchtime. Thought it was it was a great show. with good variety of models, plus full size Spitfire; glider; Pitts; and tow plane.

Thread: DX8i problems - no electric motor
14/05/2019 09:20:19

Sorry guys, I really appreciate your help, but I'm struggling to understand how to carry out the steps you're suggesting.

The throttle channel is currently reversed (otherwise it gives full power with the stick closed i.e. towards me). On the monitor screen it shows the little block moving from left to right. Although on the throttle curve screen it shows the vertical line tracking down the curve from right to left. This arrangement has worked fine for six different planes for the past year, but has just recently started to play up without me making any changes to anything.

I don't understand the concept of trimming the throttle, obviously I do this for the control surfaces with the trim switches and sub trim adjustment on the servo screen.

How do I trim the throttle ?

Sorry if I'm being a little thick here, it's obviously one of those things which would be easy to explain if we were stood in the same room, but difficult to convey via the written word.

I don't ever trim the throttle because all my models are electric or gliders.

One odd thing is that I have to reverse the throttle on all powered models. This has worked fine for the past year, but now I'm having this problem.

Looking at the monitor screen it's showing -85% at closed, and 100% fully open.

Throttle curve is Inh, and is showing 93 at closed, and 0 fully open !

I have tried creating a new model, but the Funfighter will still not work. Also tried changing receiver.

In the meanwhile I have set up on DX6i and it works normally.

Have rebound to DX8i, no beeps, but monitor is showing normal throttle movement.

Yesterday was flying electric Tucano and motor stopped midflight, brought it in OK but motor working OK on ground.

Then tried to set up electric funfighter but wasn't getting the beeps from the motor. Control surfaces all working, but no throttle.

Tried again this morning, same problem. Spectrum receiver, light on.

Rebound receiver to my spare DX6i and it fired up in the sequence with four beeps and the musical tone, and everything working fine.

I had the same problem with a different plane last week, but after numerous attempts at plugging in it was OK.

So the problem appears to be the transmitter, but I haven't found anyone else who's had the same problem, any takers ?

Thread: Undercarriage wires on Tiger Moth

Many thanks for your responses, have noted all pertinent points and will using soldering method.

Thanks Dennis, but much heavier guage than this, it's the undercarriage legs. (note I haven't bent wires yet)

Am currently reaching final stages of building 58" DB Sport & Scale Tiger Moth and now need to construct undercarriage. I have fixed forward and rearward wires to wooden block but don't have any soldering skills. Would it be an option to wrap joints with wire (as per soldering method), but then use epoxy rather than solder ?

Hi Geoff,

Look forward to watching your build. I'm nearing completion of my DBSC 58" Tiger Moth. I've found it to be an interesting build, with good quality parts. Currently a little stuck with undercarriage build (haven't done any soldering), but everything else has been quite straight forward. I've done a series of build videos on YouTube, which will be a good record.

cheers, Alan
