Hey all, im new to the edf stuff, (usually turbines)just needed an airplane when i go tdy to flight school. Picked up the a-10 from eflightline, with the himax 2015-5400, edf55, and tanic pack 2s2500. Just wantd to see what you guys thought of this setup, and what should i expect. I just got done fiberglassing it, and am sanding the excess off now. I put a cf wing, stab, and nacell spar in for strength. Not much heavier than stock, even with the excess epoxy on their, im talking like 1.8 ounces is it. Think it should be a fun one? I plan on making a lauch rail. nick

I fly my A10 with the EDF55/300H (brushed) motors, a 3Sx2150 LiPo and an AUW of 23.5 oz. This particular A10 has an all balsa fuse as the stock fuse tends to break easily (your addition of FG should go a long way to help that situation). Mine is very easy to hand launch, very stable flyer, 8.5 minute flights, balanced per plan at 57mm aft of the LE. An aerobat it isn't but she will manage the usually rolls (sloppy) and loops (tight).

I wouldn't bother with a bungee launch with the A10. With more power you might want to consider additional reinforcement in the wings. Perhaps replace the bamboo rod with CF.

I would pay attention to how you mount the fan nacelles. Mine are mounted low, the nacelle bottom being a mere 3/8" above the wing. The thrust line of the fan multiplied by the moment arm between the thrust line and the CoG will generate a pitching moment. This pitch moment tends to drive the A10 into the dirt on launch so "up" elevator is required. I believe this is the source of most bad experiences with the A10. The original A10 had very wimpy motors that generated just enough thrust to push around a 13 oz plane.

I have'nt heard anything, one way or the other, about the eflightline set-up as described.

Thanks larry. go to their website and check the first a-10 video. With the 5400 motors. The video is amazing. They didnt fg theirs, but its a rocket without. I cant see the extra weight i put on being more than 1-2 ounces. Later, nick

PIX as of tonight. I found this new spraypaint from krylon, its water based, latex. Went on nice too.

Panther,

E-Flightline has a very good reputation and the combo A-10 you bought is an awesome flier! You will be very happy with it. I was going to suggest you stiffen up the wing with CF, but it looks like you already did so by glassing. I would be curious to your final weight and will agree with Larry...handlaunching is probably going to work fine.keep us up to date on your progress and maiden flight.

Carl

thanks carl, i do have a carbon spar in the wing and horizontal stab as well as carbon rods in the nacelle mounts. should be a good one i think. ttyl

how do you put CF on the plane

I'm going to GWS EXpert.com. The price is better for a complete combo of the A-10. EDF55 + EP2030-4400KV will deliver 16.6 oz of thrust. It includes the brushless esc + a 11.1v/2000mah lipo battery. How does that compare to the eflightline offer? How does performance compare with the 2015-4100kv?

Thier prices are good!! A10 glider is 34bucks and tha sell many engines and parts.

I think you will find you get what you pay for in this instance. The 2030 4400Kv motor looks suspiciously like a Yama Electrics motor, they are very cheap and are 150 size motors, they fit tight in the EDF55-150 black housings, in the 300H housings you will need to pack them out a bit.

This motor on 3s LiPo will pull around 31 amps together, dropping to 29 amps as your battery sags and stabilises. Expect to pull 320 watts initially dropping to 290 or so, and expect the motors to last a couple of flights! (ask me how I know ) I use the 3400Kv version of this motor in a 25oz A10 and if you set it up properly with the right ESC's and get all the settings such as timing etc correct it will run very efficiently. My 3400Kv motors are 43 grams each, same as the stock 300H, they draw 14 amps combined and voltage sits at 11.15 due to the high quality of my battery pack (Hyperion 3sCLX1800 20c) This setup produces 400g thrust and flies the 700g plane well, I fly flat out the entire time and nothing gets hot. Reality is the plane should be lighter. I am aiming for 600g AUW in the next one and have a motor setup in testing stage at the moment that promises 700+ grams of thrust at 32 amps.

I agree, my setup from GWSExpert proves a bit sluggish and not up to the expected peformance of a brushless. The motors seem to strain at full power and the battery gets hotter than I care for. Throttle management is imperative and flying in a stiff wind is not recommended. I will provide additional passive cooling and see how that helps. The next size up from GWSE provides twice the thrust at 16oz. We'll see how that stands up. OR I'll pay a visit to eflightline.com.
