Baby Blender - Scratch Build

My favorite also rally2. I was thinking the same thing today about warbirds after watching wwII dogfights on the history channel. I wonder how id go about building a gullwing f4u? haha. Would be a cool challenge. As for the the thrustline. I have 2 blenders. 1 swappable. the swappable has 5 dgrees right and 3 down and the other is straight motor mount. Neither one has any torque roll problems.

HI,
New to this forum, Josh I would like to know if you used any down and right thrust angle on the motor,
Regards Craig

Hello Craig

No need for any thrust angle adjustments. Just slap it on the firewall! Thanks brother and happy building!

this is my first foam board build. i had trouble with kmart foamboad delaminating, it is a pitty because at 5$ p/s its the cheapes place i have found here in aus,

i used a Turnigy Park480 1320kv 1500mah zippy compact, habbyking servos and esc, and my oldscool jr 36 mhz rx/tx

i maidend it in verry gusty wind (im not patient), and being a r/c noob it was pritty tricky, but few good so its still in one piece,

i made a few mods, i changed the servo location to a "bonet" in the nose

i changed the undercarriage after the maden it was to flimsy, this version is good and solid but still takes bumps well

I'd like some tips on how you paint these as well. I've never been good at painting and I had a nice Fogey built last week that I destroyed when I painted the thing. I've remade it and used king size Sharpies. As asked before, you can use markers on the $Tree board with moderate success. See here...

I am experimenting with various methods to add color to the planes. The nutball was first with masking tape which ragged the paper on the plane something awful on removal. Used the same tape to add lines to the Fogey rather than paint. I used the same idea for the Wonder using black duct tape instead. The Flyer has 7 coats of orange sprayed very lightly from a distance; one pass per coat. The blue on it is masking tape. The Delta is an example of the light coat I put on it now that I am trying out paint again. I thought it looked good with the one coat (even though I slipped on the left elevon. I read where someone will wear the tape down sticking it to their shirt before applying which may work well when I do my second attempt at the blender. I have used rustoleum, yellow. Krylon, purple. off brand, orange and with a light coat no damage to the foam edges.

I got a little more daring this time with the paint, although with no surface prep it looks pretty weird up close. But as to masking I used lo tach blue masking tape and before putting it on the plane I put it on the shirt I was wearing and pulled it off twice. This left even less tach on the tape and only snagged a couple little places. I figured the starburst would just turn into a mess and it did fine.

I used Rustoleum and misted it on in several layers. We'll see if I did it gentle enough if the paper doesn't delam from the foam.

The fuse looks like I rolled it in fuzz first, don't know why but it's rougher then the wings were. Oh well, looks good from 10 feet.

Finished my Blender in anticipation of the new motor arriving from HK. I got some delamination bubbles from painting on the top wing, I think all my planes from here on out will be white with tape pinstripes. Besides, it took a full can of paint (the ground cloth got more than the plane) that doubles the cost of the plane. Like Bixler says, I'm cheap.

A nose over on the slow test flight with the suppo 1450 will have me gluing skewers to the inside of the struts as they bend very easily if the top wing takes a hit. I would have done it prior to building the plane had I realized this weak point.

This plane takes by far the most effort of any of the swappable series but really tests your building skills, that is if this series is your introduction to scratchbuilding as it has been with me.

I have a new biplane so naturally todays Frozen Finger Fun Fly had SNOW! First time in several years. A couple of nose overs and then a hand launch. I'm a tad tail heavy, I think the CG is 2.25 to 2.5 by looking at the video, never did find it on the plans, and mine hits there if I have my rather light battery packs all the way up front. Still, there is a tad of down elevator and a general wanderlust in my airplane that says it's too far aft. That just takes a little fun out of an otherwise fine flying airplane. I'll fix it by buying a bigger battery as it sucks the little 850 three cell down pretty quick. The aft CG is my fault. I goofed and cut ailerons on both wings and decided to just go the 2 servo conected 'rons route. All those connections and the extra servo are aft of the CG so that isn't good. Does have a pretty good roll rate from what I can tell and I didn't have full throw on the ailerons yet. I laid the servos on their sides on the bottom of the lower wings then put hinge points at the trailing edges of the upper and lower ailerons to bind the two together. If I didn't have such a clumsy looking connecting rod it would be a pretty sweet setup.

Can't wait to get my bigger packs in so I can do some barnstorming. I wowed and shared my Lazy Bee ripoff of the Old Fogey with guys today. If you fly a circuit of the field you get added to the award roster and receive a certificate worthy of framing, but as of yet not framed and a handshake. Everyone gets the pot luck chili, potato soup and deserts OH the deserts. 17 degrees out when I flew but 60 inside the closed up shelter house and 20 pilots in all.

Happy New Year guys and thanks for another plane.

Here is my version of the Baby Blender. More aptly named Big Brother Blender. I increased the size by 5%. It has a NTM Prop Drive Series 35-36A 1400Kv / 550W, 40A ESC, 2200mAh 3s LiPo, and Turnigy 9x at the controls. 10-7 prop mounted in pics. But, I will be flying with a 8.75-8.75 APC. I can't seem to totally get away from my roots as a Quickie 500 pylon racer.....

well then, you're just gonna need a couple of yellow pizza cutter wheels on that and your racing number back on the turtle deck. Don't forget a little Amzoil sticker or equivalent on the cowling.

It looks pretty sweet.

Tape is heavy

Tried taping for the first time. Is Okay, but added weight at the tail. Now I have to carry some lead in the cowl

Finally got the "Purple Falcon" (nod to the bad '80s after school specials) in the air. She flies very nice but I need to dabble around and find a more suitable motor, as this set up is not very efficient. Came back in happy regardless. It's a bit chopped up because most of the flight occurred out of frame. I am interviewing for a decent cameraman BTW.
