Seagull Boomerang Trainer Experiences.

[David Davis]

I have no objection to people powering their Boomerangs with electric motors. I just prefer glow engines myself, especially four-strokes but I'm not going to fit one of my beloved four-strokes into the club's trainer for some ham fisted beginner to wreck if I don't take back control quickly enough! 😉

 

PS. The last two Boomerangs which I assembled had all the parts to fit either an i/c engine or an electric motor.

I fly a EP Boomerang it has a 13x6 prop and 70amp Esc, I think it’s some where around 1000kv motor and now fly it on 60C 4cell LIPO because my old 4cell  20c Lipo’s  where getting tired. This model flys in all weathers and I don’t fly it like a trainer, loops, rolls, and goes vertical etc. Struggles with knife edge and prop hanging.

 I got it because I had an extended layoff during the pandemic and didn’t want to practise on my hanger queens and I can’t fault it, I had all the bits in stock and the model cost just over £100 a couple of years ago.

My Boomerang had the bits to fit IC or Electric and the LIPO goes in the front where the tank would have been, never been an issue swapping a battery out

Im pretty sure the purists will have a fit. This is my Boomerang. It flies easily and is a cracker. The prop is a 13 x 8.

 

Just had my maiden flight with this exact same combination and it flys a treat on an old club hack Boomer converted from IC

I took the Boomerang to the flying field last week with my trainee Frans. I had replaced my beloved Enya 50 with an OS 46 AX which I had bought at a car boot sale for just a few Euros. It didn't have a silencer but I found one that fitted from among my souvenirs. I test flew the model and landed it. Then we bound the transmitters together and attempted to fly it but we  had no response to control inputs. Back in my workshop we discovered that the switch had failed.

 

It's a good job that it failed on the ground and not in mid air.

Ha........I had a switch fail in mid air yesterday thankfully with very little damage I didn't hit anything just a gentle roll in very long grass in the next field.- I suppose its always good to practice Dead Stick situations.

I can only assume that the switch failed whilst turning it on.

The interesting thing about the switch that failed in the Boomerang was that it was not a conventional switch. It took the form of a mini jack plug and socket. You removed the plug from the socket just before flight and reconnected it after the flight. I bought two of them from a model shop in Waterloo of all places but I've thrown the second one away and replaced it with an expensive electronic switch. The problem with the electronic switch is that there's no charging lead or socket so you have to disconnect the battery from the switch to charge it up!
