bunnie Posted February 2, 2022 Share Posted February 2, 2022 Hi all, I'm on the hunt for booster for my transmitter. Can anyone tell me if any of these 2 are any good please. If not can you recommend one that I can use P.s my transmitter is a sanwa mt-44 if that makes a difference Any info much appreciated Thanks Links - https://banggood.onelink.me/zMT7/f55b97b4 & https://banggood.onelink.me/zMT7/2bfe8218 Quote Link to comment Share on other sites More sharing options...
lorrylemming Posted February 3, 2022 Share Posted February 3, 2022 What these do is put out a higher power signal by using an external battery for the antenna. If you're happy opening your transmitter and doing some soldering you should be able to make it work. Doesn't look easy though. Quote Link to comment Share on other sites More sharing options...

Hi, I know what they do but just unsure which if any is better than the other As for opening my transmitter that's light work I love a challenge 👍 Quote Link to comment Share on other sites More sharing options...
lorrylemming Posted February 4, 2022 Share Posted February 4, 2022 Ah, cool. You'll probably get more feedback in a long range FPV forum. Sorry I can't be more help. Quote Link to comment Share on other sites More sharing options...

I bought mine from eBay but it's the same. Link: https://www.ebay.co.uk/itm/252693450693 So that I didn't have to do any soldering I used this SMA male plug so it was very simple to fit on/in my radio. Link: https://www.ebay.co.uk/itm/294528826070 For powering mine I am using a Turnigy 3S lipo (as below). I was warned these boosters are power hungry so a minimum of 3S was recommended to me and nothing below 2500mAh.

Link: https://hobbyking.com/en_us/turnigy-2650mah-3s-1c-lipoly-tx-pack-futaba-jr-1.html That's the one I keep looking as it seems to be the one that is most tried and tested. Only seen 1 person document using the smaller one and that was on the arrma forum. Shame i cant get it sooner unlike the smaller one but not a problem as cant do anything with the weather at the moment. Most lipos I've seen people use were smaller ones but tbf I was gonna a use a similar one like you have listed only because I already have them. I'm seen somewhere make sure u dont turn on one with out the other as you can fry the tx. Is there a specific order? Cheers for your info Quote Link to comment Share on other sites More sharing options...

Next time I speak to some of the ROSSA guys I'll ask if any of them have heard that before. @pieman5 @Redback you two heard anything like that before?

I haven't heard such and have connected the booster up and powered it before the remote, there isnt power going back into the remote as its direct powered and only the antenna is connected. I also havent used lipo as its only rated to 5v mine got hot on AA batteries so id assume 7.4v would fry the booster. Quote Link to comment Share on other sites More sharing options...

I did think the same but thought I'd ask the question as guessed a few on here would know better Also what booster you using? Quote Link to comment Share on other sites More sharing options...

I'm using this one you linked. Just made a case for it as didnt like it being bare. I prefer to not use the booster it as it adds quite a bit of delay, making the car hard to control at 500m+.

That was the 2nd one I linked that I wasnt sure on as not seen much about them unlike the other one. Looks nice what you have done with the case.

pieman5 Posted February 6, 2022 Share Posted February 6, 2022 I'm using what i assume is a re-brand or copy of the first one you linked. If you are powering the booster from a separate lipo theres no danger of frying anything (assuming the lipo is the correct voltage) but i always turn on the transmitter first anyway and then plug the booster in. I'm only using a small 700mah 3s on mine, could probably do with something a bit bigger but its enough to last me for one days worth of ROSSA speed runs. 1 Quote Link to comment Share on other sites More sharing options...

bunnie Posted February 15, 2022 Author Share Posted February 15, 2022 These landed today so hopefully get them fitted on the weekend and tested whenever we get some decent weather 1 Quote Link to comment Share on other sites More sharing options...
GMballistic Posted February 16, 2022 Share Posted February 16, 2022 It's a really simple job to fit but just take your time and be gentle with unplugging the old aerial wire and fitting the new one. Those circuit boards aren't always the strongest. Hope all goes well. Quote Link to comment Share on other sites More sharing options...
bunnie Posted February 26, 2022 Author Share Posted February 26, 2022 (edited) All fitted was really easy and didnt take too long. I wish there was a bit more room inside the battery tray to fit the 3s but no chance and I had to take off most of the carbon skin off. Either way I'm well happy with it. Just need to test it out now Edited February 26, 2022 by bunnie 2 Quote Link to comment Share on other sites More sharing options...
GMballistic Posted February 27, 2022 Share Posted February 27, 2022 Looks good. Hope it works out well for you. 😉 Quote Link to comment Share on other sites More sharing options...
