aidan mcatamney Posted March 24, 2022 Share Posted March 24, 2022 At long last I finally got to maiden flight my new Boomerang today at the field and I wasn't disappointed. It flew as a steady as a rock and came in for a nice smooth landing. The Saito fourstroke just added to the pleasure. I'm glad I bought the Boomerang, it handled the light winds very nicely. I would recommend this trainer to anyone looking for a nice relaxing flight. 3 Quote Link to comment Share on other sites More sharing options...

Did you just use an ordinary switch? While convenient, i would always charge batterys outside of the model, should the worse happen, you would lose your battery pack, not your whole model! I've seen it happen a few times!! Quote Link to comment Share on other sites More sharing options...
jrman Posted August 13, 2022 Share Posted August 13, 2022 I have stopped using switches with built in charging jacks as the volt drop across the switch can be excessive. Not sure why this is but I have measured over 1volt drop even with expensive branded switches. Quote Link to comment Share on other sites More sharing options...

I've had one explode when it was outside the model and it set fire to two other models which were hanging on the wall, one of which took me fourteen months to build. I've never had a problems with Nicads or NiMhs exploding. I'd fit a receiver switch with a charging jack without a care Aidan provided you are not powering your receiver with a LiPo.

Hi David, I always use Nimh battery's to power my receiver and I also use good quality receiver switches with charging Jack's and never had a problem. I'm flying 36 years.

kc Posted August 13, 2022 Share Posted August 13, 2022 I think Tizdaz was thinking about charging Lipo for electric flight! Nobody takes the Rx 'nicad' out for charging with glow models as far as I am aware. Quote Link to comment Share on other sites More sharing options...

Brian Dorricott 1 Posted August 14, 2022 Share Posted August 14, 2022 I think the Saito 62 and Boomerang is the perfect partnership , plenty of power but not screaming 2 stroke power and a relaxed fly . The only time a Boomerang does something out of the ordinary is if youve caused it . I would also say that having had Saito and 4S brushless versions the Saito was a better flier than the electric one , maybe a weight thing .

Ruddy marvellous Hi, This is an old post but if you are still reading - did this set up work well got an old boomerang which owes me nothing and was thinking of this motor in an elec/4s conversion - can you remember prop size and esc size by any chance.

toto Posted May 6 Share Posted May 6 Anyone any experience of the boomerang EP version ? What I would like to know is do you have to remove the wing to replace the battery or is the front screen a hatch. Again preferably with reference to the specific EP version.

toto Posted May 6 Share Posted May 6 Thanks Ron, I kept coming up with the other version for the IC / EP convertible and just wasn't sure if they were the exact same design. Much appreciated. Inotethat the speed controller and the battery are virtually on top of one another ..... is this wise or would the preference not be to have them spaced out a bit ? No particular reason for asking other than curiosity. Toto Quote Link to comment Share on other sites More sharing options...
David Davis Posted May 6 Author Share Posted May 6 I now have an OS 46AX in the club's Boomerang. I picked the engine up for a song at a car boot sale, minus the silencer but I found one amongst my souvenirs. I didn't want to risk my beloved Enya 50 in the clumsy hands of incompetent beginners. I recovered my Boomerang's fuselage and tailplane last year as it was starting to look very scruffy. 1 Quote Link to comment Share on other sites More sharing options...

Toto Personally I wouldn’t have them arranged that way but then again I wouldn’t leave the engine mounting bolts protruding back into the vicinity of the battery either! 2 Quote Link to comment Share on other sites More sharing options...
aidan mcatamney Posted May 6 Share Posted May 6 The Boomerang is a great trainer Toto and one you wouldn't be disappointed with. The EP version would be very handy for you. Quote Link to comment Share on other sites More sharing options...
toto Posted May 6 Share Posted May 6 The seed has been planted for some time but the Supercub is doing such a good job. Not just that but I have the Domino to resurrect again whatever is causing those ESC failures. If I do sign up for another trainer though it will probably be the Boomerang. The benefit of having another of these type of kits is it forces you to get the install of the servos etc correct rather than the pre-installed ready to run from the box type. ( in my mind anyway ). I did notice that the EP version was about 150mm narrower in terms of wingspan than the ( red ) IC / EP version. That puts me off slightly but on the plus side, the EP version has the front nose cowl which I feel tidies it up a bit. Hmmm .... horses for courses .......

David Davis Posted May 6 Author Share Posted May 6 Toto, the Boomerang kit comes complete with all of the parts for mounting either an electric motor or a proper engine. Don't you have a 46 two-stroke somewhere? It could be a challenge for you once you have learned to fly. Quote Link to comment Share on other sites More sharing options...
toto Posted May 6 Share Posted May 6 Yes David .... I have two force .46's but going on my experience with the Arising Star ...... it will be once I have learned to fly and gained enough experience on electric. My last attempt at IC was nothing short of a disaster. I'm in no hurry to repeat it, at least not at this stage of my journey as I am only starting to see real progress and want to keep it at that. The force .46's will have their day ..... 😄 cheers toto 1 Quote Link to comment Share on other sites More sharing options...
David Davis Posted May 6 Author Share Posted May 6 1 hour ago, toto said: The force .46's will have their day ..... 😄 I'm glad to hear it but then I'm an engine man and appreciate the challenge of setting up a well-tuned engine. I understand why novices prefer electric motors because they are eminently reliable, smooth, quiet and clean. For those of us who don't mind getting outr hands dirty, i/c engines are our preferred power source if only because on a pretty standard tank you can fly for twenty minutes if yiou want to, ideal for training beginners. That said, beginners get tired quickly having to concentrate for long periods. Us Greybeards had to get to grips with i/c engines in the old days because electric propulsion was in its infancy. I/c engines are not difficult to master. On a two stroke glow, there are only two needles to adjust. I look forward to hearing of your experience of learning to use i/c engines, meanwhile, keep up with learning to fly on electric models. 3 Quote Link to comment Share on other sites More sharing options...
Zflyer Posted May 7 Share Posted May 7 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. Quote Link to comment Share on other sites More sharing options...
