fly boy3 Posted April 24, 2023 Share Posted April 24, 2023 Hi all, at last have joined 21st century and bought 2.4 gear and a used electric plane , my first. Considering that both are new to me, I am thinking of putting my trusty 35 mhz receiver in to the model and using my Futaba tranny for maiden flight. Would the voltage from the esc be suitable for Fut. receiver, or should I use a separate receiver battery. Thanks Quote Link to comment Share on other sites More sharing options...
Peter Jenkins Posted April 24, 2023 Share Posted April 24, 2023 Welcome Alfred. I would not use your Futaba 35 mHz gear as there might be issues with glitching from the electric motor operation. 2.4 gHz is "immune" to electrical noise generated by electric motors. Many motors will not, therefore, have any electrical noise suppressing capacitors fitted. IMHO most 2.4 GHz equipment is bullet proof. It is also immune to being shot down. You will not be worried by setting up the 2.4 stuff other than the need to turn down the Tx power for the range check. Depending on what make your 2,4 kit is, and if you have any manuals for the Tx, it is usually quite easy to do if you know the procedure. Post what make of 2.4 you are using and if you need to help in how to do the range check. Other than that, it's exactly the same as with 35 mHz kit but may have a few more bells and whistles in what it can do. Quote Link to comment Share on other sites More sharing options...
J D 8 Posted April 24, 2023 Share Posted April 24, 2023 I still use 35 for some aircraft, just can not be bothered to change them and I like using my Futaba FF7 transmitter. Two aircraft are electric and neither have ever had any glitching issues and have been in use many years. Both are however powered by brushless motors which do not have the arcing/sparking electric noise issues on brushed motors. 2 Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted April 24, 2023 Author Share Posted April 24, 2023 Nice looking model JD. Am I correct in assuming this model is fed by lipo which also feeds esc and you 35mhz receiver ? Thank you. Quote Link to comment Share on other sites More sharing options...
J D 8 Posted April 24, 2023 Share Posted April 24, 2023 Its a Ripmax Coyote with Corona 35 band RX and motor fed from a Wasp 33amp esc powered by a 1300 3s lipo. Cant give details of motor as it is glued in and details are printed on the bottom. Cheers, John. Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted April 24, 2023 Author Share Posted April 24, 2023 Thanks Peter for really interesting information I was unaware of. Due to m y age and budget I purchased a FlySkyi6 after some internet research. It has no system for range check , other than 2 people with mobile phones at a distance from each other lol. I could have a bit of practice with my new radio gear before deciding which to use. Thank you. Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted April 24, 2023 Author Share Posted April 24, 2023 Hi John, the model I was going to maiden is very similar to your photo. It is an E flite/ cherub glider, even has same colour scheme.lol. Thanks 1 Quote Link to comment Share on other sites More sharing options...
PatMc Posted April 24, 2023 Share Posted April 24, 2023 Hi Alfred, I'm with JD 8 regarding 35 Meg V 2.4 Gig, though since you now have 2.4 gear why not use it ? I would, even if only to obviate the chance ( albeit small chance) of a frequency clash. Had a quick google for the Eflite Cherub details - AFAICS it hasn't been on sale for quite some time but when it was it had a brushed motor installed. It would be worth checking if yours still has or has been upgraded. In case you are not aware - the quick way would be to check if the motor/esc connection is 2 wire (brushed 👎) or 3 wire (brushless 👍) 1 Quote Link to comment Share on other sites More sharing options...
fly boy3 Posted April 24, 2023 Author Share Posted April 24, 2023 Cheers PatMc, will do. Cheers Due to some ongoing problems logging in to the forum, my user name was OldFlier. And for years before that I was FlyBoy3 lol. Hoping admin can sort it soon. Quote Link to comment Share on other sites More sharing options...

fly boy3 Posted April 24, 2023 Author Share Posted April 24, 2023 Hi PatMc. You were correct. My model has a brushed motor installed. Seems to have answered my conundrum too. Will have a little practice with my 2.4Tx first. Thanks all for your help. Quote Link to comment Share on other sites More sharing options...

Simon Chaddock Posted April 24, 2023 Share Posted April 24, 2023 Alfred A brushed motor is much more likely to give interference problems particularly in the condenser fitted across the +/- motor terminals is old. As stated 2.4 gear is almost immune to brushed motor interference. My first foam plane had a brushed motor and to be fair it gave no problem even on 35 Meg however driven from a 3 cell 11.1V LiPo rather than its original 9.6 volt NiMh battery the motor brushes didn't last very long. Replaced by a brushless motor with its appropriate speed controller. It gave more power, was electrically more efficient and only 50% of the weight. That brushless motor is still going strong 12 years on as apart from the shaft ball bearings there is nothing else to wear out and it is still on 35 Meg.
