Default Elmers Foam Board SloFly 28 (Scratch)

Hi all,

Ive been having lots of fun with the Nutball I recently built, but I feel like building something new with the same guts. So Im gonna try the Slofly28 . I dont have any EPP, just Elmers Foam Board (FFF basically), but it shouldnt be a tough "conversion". I know it will be a lot less durable and the charm of flying worry free wont be there but I feel like building something.

Electronics will be Blue Wonder motor, 10 amp esc, 2s 800mah batt, 2 9g servos, one HS-55, 9050 prop.

Comments appreciated.
Pics up soon...

I built my last Slofly out of Depron...I bet you'll love it. Less flex than the EPP but not near as tough.

Great to hear.
I think Elmers is a bit less brittle than depron, but heavier and less stiff (both good and bad). Just finishing getting the paper off...

I will have to make the elevator and wing slots a bit smaller because of the 6mm Elmers vs 9mm EPP correct?

Yep, just make your slots the size you need. Other than that I built mine just like I made the EPP planes. I have knocked my motor mount loose a couple of times but no foam breaks so it is an easy fix. I'm afraid if I tried to beef it up things would start to break.

Yep better to break the foam than the motor.

I don't think there is enough momentum or weight to break the motor...trust me, I've tried .

I have been using hot glue for the mount stick and there is just not enough foam there to hold it. Here is a pic of it loose right now. This has happened a couple of times but like I said, as long as nothing is breaking I think I will just keep gluing it back in place.

I guess I could always try to not hit the ground so hard but where is the fun in that .

Lol. Im planning on doing a firewall mount because I dont have a stick (or mount) and I dont really want to wait for an order... Besides, I like the RCPowers break away motor mount idea, works well for me.

I had to Google the RCPowers breakaway mount. I like it, I bet it does work good.

Worked OK on my Nutball, probably is better with slightly larger motors. But it did absorb a lot if impact in my crashes.

Almost done, should finish tonight. Nothing too out of the ordinary in building it, except for a few minor mistakes. Packing tape hinges, Elmer's Glue for major joints hot glue for the servos and small stuff. Btw, this will be my first 3D plane

Dial in plenty of expo and set a low rate of 60% and you'll do fine. Don't forget your rudder! The plane actually flies better if you use the rudder to turn. They don't bank and yank like most planes you are probably used to.

Finished it up a while ago, ive just been kind of busy. First flight was pretty bad, I added some more strengthening skewers and second flight was bad, just didnt feel like enough power or something. I crashed it real hard one more time, nothing broke but after that the motor started giving more power, like its supposed to. I also played with the throttle trim, works great now. So 3 flights so far...

Stick with it, it will get easier. I know it helps me a lot to get some one better than me to fly my plane. The set up advice really helps.

Remember when the winds are up you can still fly...in a way it's even easier. Just point it in the wind with the nose up high (harrier) and try to keep it in one spot. With enough practice and using lots of rudder and throttle you can get pretty good at it. It will help your hover on the days that the winds not blowing.

PaperAirplane,

I started flying with Sloper Steve's Slofly 28. A wonderful airplane!

I had trouble flying the plane and added a shock spar to mine. I was 63 years old at the time and arthritis was a problem with my hands...anyway, I've included a picture of my latest SuperSlo 30"...the Slofly 28 has long been sent to that big hanger in the sky.

The Superslo is made of 6mm 1.9lb EPP. Disregard the airbrakes, they aren't really necessary but come in handy for hovering practice. The key to flying these planes is to fly them slowly. I started out trying to go to fast and caused a lot of needless damage. When I finally got it into my head to slow it down, thanks to a friend of mine, I started to really make some progress.

Regards,

Hankg

Good advise, Ill keep that in mind! My motor BW does not seem to have enough power when I fly in 5 mph wind, I think I may have to use a lighter battery.

I use a 1700kv BW with a 2S 450mah and a GWS DD9x5 prop.

i kinda like the 8x4.3 slowfly prop (vs the 9*5) with 2s 800 and 1700kv blue wonder.

i'm using it on a blu foam Tim hart ult-bipe


it's been 10-15 mph here lately and the motor will keep up with the heavy gusts

A lot of guys also like to use a 3S outside in the wind. I've never ran a 3S so I'm not sure on battery and prop size.

Paper,

I've always used a 460 milliamp 3s Rhino with a 8x4.3 prop. I've always flown outside, never inside, and over the last year, as I've tried to increase my flying skills, I always try to keep the speed to a minimum. Any wind over 7mph adds a lot of angst to the flying because the plane is so light.

My friend has gone to a 9x4 prop this year with a 460 milliamp 3s and swears he gets better control doing acrobatics. He doesn't push the speed either and flys successfully in a much smaller area than I do...he's also twenty years younger than I am.

Physics plays a giant part in flying this plane successfully. Momentum (energy) equals Mass (7-8oz) times velocity times velocity. The lower the velocity you fly at, the less momentum (energy) the plane exerts on itself when it hits the ground thus the less damage to the airplane. When I began, I actually hit the ground so hard that I snapped the 3mm motor shaft in the Blue Wonder. Finesse is good with this plane...it's designed for it.

Regards,

hankg
