- This AeroFoam MB-339 from @Banana Hobby is a model I recently received and I'm quite impressed with it! It's a really good size and is available as an EDF or turbine powered model. This is the EDF version which comes with a 105mm EDF pre-installed which flies the model really well. The finish is really nice and the camouflage scheme looks great on the airframe! Full review coming soon! :) #MB339 #MaidenFlight #RCJet

Awesome video. Looks great in the air , and on the ground . 👍
Thank you! 😊
This is pretty cool
Great video Chris. I purchased this model just last week. Going to hold off on the build until your "build" video comes out. Thanks man! 👍
Awesome! You’ll like it, but does take a little work in assembly. My full review should post in a couple weeks. 😊
Nice flying 👌 👍
Thanks!
AWESOME AS USUAL !
Thanks man!
Great video and flying as always. Always enjoy your clips. That thing looks like a real beast. Bet it is fun to fly.
Same!
Thank you! She is a fun one. I especially like the size of it.
Hi Chris like your new jet enjoy it
*Let the Sunshine In .*
Nice looking bird ,& great review
Thanks! 😊
@@Thercgeek you're welcome
hay Chris nice review, thanks
Thanks!
Nice Chris!
Thanks!
Very good and informative vid again Chris, thanks for your time. The model looks stunning, but I think that the fan needs some balancing. Greetings from Belgium 🍻
Thanks! The balance isnt bad on this one, but some static balancing wouldn’t hurt for sure.
Great flight Chris, she really a good looking bird. 👍🏻
Thanks man!
@@Thercgeek I forgot to ask Chris, this bird comes in Balsa as well?
No balsa, just the foam version that I’m aware of.
Chris. Banana Hobby has some nice large EDFs. 12s power does put a hurtin on lipos. Ahh maybe one day battery tech will catch up in the RC hobby so you don’t have to think about landing right after takeoff. lol. Again. Welcome to the south and all the luck for you and your family. 😉
Thanks man I’m excited for the future! On the flight times, fan tech is a big part of it too. I wonder how a jetfan might do in there and how that may improve the flight times.
I just saw the new announcement on your webpage, Chris. Congratulations! Wishing you the best of luck on your move and on your business ventures!
Thanks man!! I have an announcement video posting next week along with a giveaway contest. 😊. Be sure to enter once it opens!
@@Thercgeek That’s excellent! Thanks! I definitely will. 😎👍
Good tip with the gaffer tape … I’ll have to try it as my nose gear doesn’t go up properly, but only when in flight i.e. when the fan is running 👍🙏🏼⭐️
Thanks for reviewing the MB-339. I hope you review some more of these 105mm foamies, T-45 and L-39. Would be great to see someone do a custom extra-light 6s version too, with something like a Jetfan 110 pro or Midi Evo 100.
Thanks! We’ll see where it goes, These larger birds are quite nice. I am curious how this would do with a JetFan100. I’m hoping to try that at some point.
Cool beans Chris
That is a cool plane
I like it! 😊
Pretty sick model. Wouldnt mind a turbine version. Liking the new vid format :)
Thanks dude! 😊 Turbine version would be rad. Nice like flight times and vertical for days I’d imagine!
Now Thatsa Nice a Plana!
Unreal an El dente landingsa to a Youa.
Haha, thanks! Funny that there was a “translate” option under this, haha! Google tried, but couldn’t translate it. 🤣🤣
I have been eyeing this one for quite awhile and never seem to pull the trigger. I have always liked the MB-339. I almost purchased the kit version years back from FlyFly.
It’s a really nice flyer.
How many amps is your system pulling. Mine with the JP Hobby setup on the v2 PNP only pulls 99-103 amps when it should be closer to 130 amps. Not sure if changing to a JP 150amp esc over the Hobbywing Flyfun ESC will make a difference.
Great video! Curious about the two cameras you use. What are they? It looked like you had one from above and below. I believe you said you used frog tape to hold them. Is that correct?
Thanks! I’m using runcam2’s for those shots and yes, used frog tape to hold them in place. The hope was to minimize any paint lifting under the tape.
Very nice Chris!! What receiver are you using and how many channels?? And recommendation for the Banana hobby L-39, thanks👊🏼
Thanks man! I’m using the AR10360T and using 9 out of the 10 channels. I put the steering and rudder on separate channels. Without that, you can get away with an 8 channel pretty easily.
@@Thercgeek thanks so much for the reply, I was thinking of going with the spectrum 10 channel myself for the aero foam L-39, thanks again 👊🏼
gawd that thing is humongous...
Love your videos! What kind of camera are you using to get those wing shots?
Thank you! I’m using runcams for those.
Would putting the camera under the canopy, in the front seat area give a nice view of what the pilot might see during the flight? I would like to see a short video of that, if possible, thanks, T
It would and I can look at doing that. The thickness of the canopy may distort the view though. I guess we’ll see! 😊
Shame that the squadron badge on the tail is not applied correctly. It's such a shame that they didn't look at photos before they applied the decal.
Hi Chris , did you have to modify or upgrade anything or is it 100% stock? Thanks Will
Excellent video
This is stock with the JPHobby brakes that banana hobby provides with the kit. There are some plywood plates that I removed to open up the battery area and I also drilled holes through the nose area to feed servo wires forward to where I placed the receiver but that was mostly it that I recall. It’ll all be covered in the full review. 😊
@@Thercgeek awesome looking forward to it, thank you Chris😎💪🏼
make a great little turbine jet
Yep! They actually have a turbine version of this model available.
Where did you get the huey model from I love it I want t make it!
The info is in the video description. I’m not sure where the fuselage can be had though. I’m not sure if they are still made.
Super :) / 35 C Akkus hast du damit schon mal Probleme gehabt? Da der ja schon ziehmlich an den Akkus saugt
No issues with the 35c at all. They are my go to for batteries. 😊
@@Thercgeek OK thanks . was only the question because 50C - 70C would be optimal. But if the batteries go along with that, I don't need to get any new ones either ;)
I'm lost; what is the 3s lipo for again? The UBEC?
Yes, it powers a ubec for receiver power.
Vn, I thought when you check cg on a low wing plane it has to be inverted?
It honestly doesn’t matter, You can check cg upright or inverted. On a low wing airplane, it can be a little easier to handle and place your fingers when it’s inverted vs upright which I think is where that probably originated.
@@Thercgeek thx
How was the static balance of your edf?
You know, I didn’t check it specifically, but running it balance seems good!
What mini camera do you use ?
I’m using runcams for the onboard stuff.
Is this Hall field? I fly there all the time! I live like 5 mins from there
This was the Temecula valley flyers field. Not sure if that’s called Hall field or not.
@@Thercgeek ok yes this is hall field I fly here a lot! How often do you fly here? We should meet sometime
I’ve only been there the one time and it was a great spot. Sounds fun, but I’ve actually since moved across the country though (as of a month ago).
@@Thercgeek oh dang ok
🇺🇸🇺🇸👍🏼😀
Im really thinking of getting this exact same jet but sum say the 105 isnt enough power is this true
Honestly, I find the stock 105mm fan provides nice scale like power. It’s not the most efficient though. Runs through a charge pretty quickly.
@@Thercgeek thanks
Whats your favorite size EDF? mine is 80mm for sure..
I think I’m partial to the 90mm size. You can get some pretty great flight times with them and also fly a good sized model with 90mm too.
Paint job looks far superior quality to Eflite 90mm Viper from afar, how is it up close?
The paint and finish on it is quite nice! They’re using a much higher density epo foam since these are also packaged with turbines and that provides a nice smooth finish.
@@Thercgeek thanks for info. I’m going to repaint my Viper in F1 racing colour scheme.
Oh, that should look sweet!
:)
Can E-Flight make a 6s version...
12 is too many
A smaller eflite one would be pretty cool
Which one easy AF L39 or AF Mb339
I haven’t flown the AF L39, but based on the longer wing and tail of the mb339, I’d expect it to be a little more forgiving.
8:30
Chris, where U moving to?
We’re moving to Tennessee. 😊
@@Thercgeek Sweet! I was thinking it would be cool if you were coming to Florida:) lots of folks are flocking here.
@@Thercgeek The welcome mat is out and we will reserve a parking spot at the field for you ! - Larry
Thanks so much Larry, we’re super excited for the move! I look forward to flying with everyone at Cane Ridge. 😁
Wow is everybody ok with 3 or 400 or more for foam? Hmm
I hear you. This is a pretty large model though and with the costs of everything the way they are, 300-400 doesn’t but as much as it used to unfortunately.
Don't get me wrong it's awesome looking. I worked in the hobby trade for 20+ years in 2014 I moved on and HD been out of the hobby for a while I have 5 or 6 micros I fly in My yard so recently I wanted to get a bigger plane and was just shocked at the prices. I know what the distributors and hobby shop paid for them so I guess inflation? Maybe the foam got more expensive ha I don't know but I guess the days of a larger foam plane under 200.00 is gone
Good review and Looks nice but I just can’t bring myself to buy anything from Banana Hobby. Their reputation going back a long way is awful.
I understand. Bare in mind that they are not the company they used to be (in a good way) and these new airframes they are making are nothing like those old days at all.
Man, priced out batteries, plane, over 1200! And that is without some of the upgrades! Easy 1600 if u do it right! Sort of over priced imho. Whatever. I guess if u dont have family or make shut ton of bucks... lol. Enjoy! Looks awesome.
I understand, It adds up. For what it’s worth, I didn’t find that the airplane needed any aftermarket mods. The jphobby brakes are included with it. Otherwise, just needed some time to get it together.
@@Thercgeek That's good to know! It's on my wish list, but might be some time before I can work my way to spend that much on a foam electric ;). Being old school in the hobby (started in 85), I still have a very hard time coming around to the prices of these foam models. Gas motors, ARF balsa is still cheaper than some of the Foam set ups! Great videos BTW. You have a lot of inspiring stuff going on! Keep up great work.
Flight time?
3-3.5 minutes is about it unfortunately with the 6250mah packs.
@@Thercgeek that’s great, love the sound of it, so cool
This chap flew a 6s BH Viper 120 (on Li-ions). It would be great to see more 6s setups on these types of large jets, especially by an experienced pilot like yourself.
czcams.com/video/z8JusoNRYmY/video.html
Wemotec has a stock 6s setup for Midi Fan Pro 100, HET 700-75-1750
There must be a similarly good 6s setup for JetFan Pro 110 which doesn't draw too many amps.
These setups could work great in these 105mm foamies, and possibly in some balsa and composite models too.
In all honesty, the higher the voltage, the better electrical efficiency you can get for a given power draw (I.e. lower current). And while 6s sounds interesting, at this size my preference really is to run higher voltage to get the current draw down for longer flight times. I do think with a more efficient fan in this, flight times and performance could be notably improved (my opinion).
Ah but you reduce the power on 6s so current stays the same as on 12s. 3kW instead of 6kW. But its about how you prefer to fly. I prefer to fly very light with low wing loading. 6s at same current as 12s allows shedding of a lot of weight. If you look at MidiEvo100 1750 6s setup it has one of the highest efficiencies 0.63 compared to their higher voltage setups.
Understood, that will work when the airframe is kept light. Because this one is based on a turbine airframe, the weight is a bit heavier than it could be. I could see this working well with a nice light airframe.
@@Thercgeek If you get round to it please give it a try. Its nice and controversial you will shock many people by showing it flying great on 6s. On rcgroups no one will believe it :)
I am going to try 6s on a HSD F-16, but with non-scale landing gear to achieve a low weight.
MB-339 EDF version all-up is 7.2 kg. I estimate by going to 6s and losing some bits (non-braked wheels for example) all up could be 5.4 kg with MidiEvo100 1750 a single SMC 5300mah 6s graphene. Or a Jetfan 110 on 6s may be even better (but I don't know which motor would work). This should fly nice and scale on 6s. In Wojtek's video above he flew the much bigger BH Viper 120 on only 2.6kW 6s at a all up weight of 6.1kg, it flew beautifully. Do check it out when you have time.
Get the $40 pilots
Or, I could print my own. 😊 I started that process, just haven’t finished that yet.
Not sure why that nose gear is retracting the wrong way, i don't get it especially for that kind of money. A shame for that kind of high end foam edf jet.
I get it. Honestly, it takes the right person overseeing the development to ensure details like this are correct.
Guess no actualy builds a plane anymore
Well, for what it’s worth I will be transitioning to more build content going forward. 😊 while building is more scarce these days, I’m hopeful it’ll be helpful for folks.
Those Model building COMPANIES, NEED TO MOLD THEIR JETS AND OTHERS OUT OF ALUMINUM. TO MAKE IT WORTH BUYING. Foamies break up and your out of luck fixing it. Wasted cash.
While I appreciate the sentiment, honestly aluminum is not the way to go. You’ll end up with an extremely expensive model. Composites are where it’s at for the pinnacle models out there. Hard to beat in terms of construction time and weight.
@@Thercgeek Sorry if my comment was rash. I have a tendency to seem rash, or other. Lol.
I really said that, mainly pertaining to the Really fast planes, especially JETS. Because the Stress on Wings due to speed, causes structural damage, even loss of whole plane sometimes. Also, mounting areas of Retractable landing gear Tare's apart, causing damage, or also loss of plane too.
No worries at all, I didn’t take it that way. I still stand by the composites statement though even for jets. For weight and strength at sub scale sizes, it’s very hard to beat and aluminum will be heavier and more time consuming to build.
information. the use of cheaters does NOT make-up for defective internal edf air flow design.!!!
for any edf thrust system, the MINIMUM Optimal Intake and optimal exit areas are the SAME.!!!
that value equals, the Effective Swept Areal of the impeller.!!! that value is determined when, the area of the cone/spinner is subtracted from the impeller area. divide that value by pi, to get the diameter of a circle.
an edf does NOT draw like an engine does.
consequently, scale air intakes are almost Never large enough (for an edf), and cheaters do NOT work.!
in order to be effective, edf intake area Needs to be oriented perpendicular to the air flow; and it should not be located where laminar flow is dominant.!
when the intake/exit areas of an edf-powered model are nominal, energy efficiency is also Nominal; the edf will be quieter and its motor will be stressed less; flight time duration should be increased, a bit. googletranslate
