Six months of full-contact Baby Blender combat

Two Baby Blenders & six months of full-contact arial combat 


The Baby Blender was my first real scratch build. Around the same time my piloting friend and instructor, Chad, also built one. We were proud of our shiny new planes and treated them with care. 

However, one day we were admiring how tightly they could turn, and how swiftly they could climb, and a dark thought crept into our minds - what would ribbon cutting be like with the Baby Blender? 

So began the slippery slope. Soon two planes in the air meant only one thing - combat. Soon the ribbon was nothing more than a guide to help us track our enemy with the sole  ambition to smash them out of the sky. And soon our planes began to look more like monsters than babies: chopped, smushed, ripped, punctured, battered, and sometimes even smoking. It was the best six months of flying ever, and honed my skills to a keen edge. 

Watch the video below to see a compilation of our progress into the dark world of to-the-death arial combat. It is mostly on board footage, and we only captured a small fraction of the catastrophic collisions we survived (because 808 cameras just turn off by themselves). And read on for more details of how the planes fared. 

 

 

The set up:

The two planes were stock Swappable Baby Blenders, with tape covering. Initially we used small motors and 11X3.7 props, but quickly moved up to NTM 2826 1350 KV motors. The competition was fierce for who had the power to climb and roll sharply, and this eventually led to 11X5 props. This was GREAT in the colder weather, but soon we started killing motors. I had more trouble with this, and killed at least 3 motors and one ESC. This led to going up to 36mm motors, but that is really hard to fly on a Blender as the balance is way off. They don’t land, they fall out of the sky like a rock. 

 

The rules:

There were no rules. We ran crepe paper tape behind our planes, which was originally the target. When I say originally, I mean for about a minute, then the planes were the target. But the ribbon is really useful because it allows you to keep track of the other plane and which direction it is moving in from the corner of your eye. It was essential for lining up the enemy for a lethal strike. Ribbon cutting did happen, but by mistake, and usually led to the winner crashing with ribbon wound around the motor. It was a poor substitute for a real victory, which was knocking the other plane out of the sky, while staying airborn yourself. 


In a fit of obnoxiousness, I took a picture of Chad’s plane and began taping “kills” on my fuselage whenever I took him down and stayed in the air (see below). This became an unofficial but not very well recorded idea of “victory”. 

 

The outcome:

So how does a Blender hold up? The short answer is GREAT! It is hard to image a plane taking the beating these two planes too and still flying. They were crashed every imaginable way. They took 8-10 full speed head-on collisions, some so violent that they ripped 3/4 of the motor mount points off. They ripped into each others wings, bellies, tails, and everything else. Chads plane had the top wing “removed” and he kept fighting. He also had half his elevator ripped off and kept in the air. My plane got so loose that it would not take off and I had to discus launch it, but risked the fuselage falling off sideways if I held it down too long. And still they flew, and flew well in fact.

Amazingly this did not result in a hit


Most of out repairs were in the field, since we would have more than one big crash every session. Tape was all we used, and lots of it. Hot glue when you get home, and NO new parts. They flew with big holes in the wings (mine acquired a big hole that made it easy to carry around, like a handle), smashed control surfaces, and thrust angles all over the place.

Typically the Victor would be humble. Here I am doing a victory dance over Chad's broken plane

The Blender might be the perfect plane for full-contact combat. It flies fast or slow, it can turn on a dime and you can keep it in a VERY tight space (important for safety). And because it is kind of a floppy plane to begin with, it takes catastrophic crashes very well. We think it flexes so much it does not break. 

I should end by pointing out, in case it is not obvious, that Chad gave out at least as good as he got. I had some fun at his expense in this post (and since I had the camera the movie makes it seem that I am always chasing him), but he is a way better pilot than I am and just as often as not he flew away while I did not. I am actually amazed I ever managed to take him down at all. 

Before and after

Very entertaining article and video. Great editing! Besides being a credit to your (and Chad's) flying skills it is also a great credit to Flite Test for their fantastic designs and interest in the RC hobby. I myself did not have as much luck with my BB (it was my first and I was inexperienced) but every one of their designs I have built has flown "phenomenal"!

Chad here... Great article Patrick! Brings back some awesome memories and makes me thirst for more blood! I love the before and after photos... Combat really improved your flight skills - you have become a great pilot because of this crazy fun! I live that we could have a battle contained within a baseball diamond - the BB is an awesome plane, and I will be making a new one very soon for the coming combat season!

PERFECT I mean completely perfect timing.

This spring my son wants to start flying.
We looked over all the "beginner" planes and he decided he liked the BB.
I have a micro tiger moth so he related to it.

But once he saw your video it settled it for him.
Son "Once I get good, we could do follow the leader and so on?"
Me "Of courseā€¦"
Son "What if I crash?"
Me "Don't worry about it, parts are cheap and it is just $ store foam."

I've even convinced my 3 other friends to start building their BB's.

What I do like is the wing span is a touch smaller so we can put 2 in the trunk of the car.

Again thanks. Can't wait for summer. It has been a long one here in Ottawa.

Hi Andre,
Excellent - the BB is an awesome plane but note it does respond quickly... Rolls etc can be quick if you pull hard on the stick (this is what we like about it!). But just give him some expo and it will be a great plane for him as there is a lot of lift and it is so easy to repair.
We have had a lot of rain here in Vancouver, so Patrick and I are chomping at the bit too. We have 3-4 other pilots interested in building a BB as well so that we can have a swarm of them in battle - that will be awesome! We even have one guy flying an FPV quad that has volunteered to film from within the mix - now that should make for a cool video update!

I second Chad's comments. I actually flew mine pretty early on and had lots of expo and rates dialed down, and it was an easy flier. I also have another, still pretty one (in my post on the micro blender I made) that has a 11X3.7 SF prop, and that is really docile, but flies beautifully. I would suggest that set up since it has lots of power but not much speed. One suggestion is to sling the wheels REALLY far forward, because otherwise it is hard to take off - it goes nose forward. I put mine about 2" forward of the bottom wing leading edge. Big wheels helps too.

This was great! Seems like you've had a blast, which in turn makes me even more inspired for the hobby in general. Really liked the music too, it made me happy listening to it.

Simply AWESOME!! Flying is fun, but combat is CRAZY fun!!!

The few times I have had a chance to do combat I have never laughed so hard in my life!!! I think Zagi's are a better choice for combat, especially if you have a slope site. One time when I was doing combat we had 13 wings in the air at the same time... it was INSANE!!! but unforgettable!!

Thanks for sharing and bring back some awesome memories!!

Great on all the tips and suggestions.

I agree on the landing gear. My Dad's trainer did that cost me a few props. My cub trainer had the gear forward and would just jump into the sky.

I'll start working on the plans tonight. I will make a few changes. Mainly to enclose the battery.
I want to protect them ;)

Thanks for the inspiration.

This is going to be a great summer.

Hey, I totally agree about the battery and have a suggestion. If you look at the pictures of the red plane, you can see there is a little foam/tape box around the battery. Also, I put a two-sided velcro strap inside the fuselage when I make these planes (check one of my build videos to see this during construction, but you can also add it after with a bit more effort). Then you place the battery as normal, put the foam box under it, then use the velcro to attach it. You can see it hanging off the bottom of the picture above called "starting to show some wear".

It works really well to keep the battery in place, stops major impacts, and also keeps it from sliding forward into the prop.

Great to see the Baby Blender's standing up to so much abuse!!! :) Having thrown the planes about so much you probably have more experience of their strengths and weaknesses than most other BB flyers. I'm asking this because my BB died - the bottom wing was the main problem - it just collapsed along the wing cut that insets the wing into the fuselage (which I felt was predictable considering a lot of the strength of the wing had been compromised). When I built my TRIBEWT monoplane I reused a lot of the BB build detail, but kept the wing intact and cut the recess into the fuselage instead (I've repeated this on every subsequent low wing build and also my AVRO 539B biplane. I feel 'my' solution keeps the wing strong, and if/when I build another BB I'd use the same detail and keep the wing intact and cut away the fuselage. What's your experience of the resilience of the lower wing? Have you had any failures? Thanks, alibopo.

That was certainly one weak point. I strengthened mine by gluing something hard with the same profile cut out onto the inside of the fuse where it meets the wing. That mostly fixed it. As for the wings themselves, after some bad crashes I just shoved a piece of broken tent pole into the wing beside the spar. That solved that.

I thought about making one with an integrated bottom wing (like the spitfire). Ultimately however being stiff and solid might work against you in a crash. Sometimes being flexible is better, as long as you bounce back into shape. My theory with the blender is that it is so floppy it can take a lot of crashing without actually breaking anything.
