Highly scaled, large size EPO ARF aerobatic fighter jet with a big 90mm EDF system. The Alpha EDF jet comes mostly pre-built and includes a 90mm EDF fan unit.
This well detailed and strikingly painted EPO foam jet uses a 90mm ducted fan unit to provide fast throttle response and a high top speed.
This ARF model has many special features, such as being retract ready, carbon reinforced wings and flaps for great slow-speed handling. The canopy uses a spring loaded latch system that ensures a secure fit, and is easily removable to change batteries.
This is an ARF model, so you will need to add your own electronics such as motor, ESC, servos, retract system and radio gear. The Alpha includes landing struts w/wheels that can be fit to which ever retract system you choose for this model. It will accept mechanical or electronic retracts with ease. It also includes all required hardware such as screws, control rods w/clevis and control horns.
This is an exciting looking big size EDF model that will impress everyone at your next club meeting! Specification: Wingspan: 1020mm Length: 1380mm Flying Weight: 2500g Channel: 6ch Motor: 1600~2000kv Brushless Inrunner (required) ESC: 80~100A (required) Servo: 8 x 9g (required) EDF: 90mm
Required: Your own 6ch Radio System 1600~2000kv Brushless Inrunner 80~100A ESC 8 x 9g Servo Retract Units x 3 (electronic or mechanical retracts - will need 3 x mini servos for mechanical) 3500~4500mah 22.2V 6S Lipoly
P.L.E.A.S.E HK, give us an estimate when this bird will
be stocked in the European warehouse. It's already available since the beginning of this year, so it could have been stocked in Germany by now....?
TIA and cheers, JeffBr.
I've read other comments on CG that its from the leading edge of the air inlets and it looks like it in the manual but hard to see. Mine is ready and should fly this week. Has anyone used the 185mm from intakes as a CG mark?
Anyone can recommand wich battery is best to be used according to cg, weight, balance ans size of battery compartment. Just to check if hobby spec are accurate for this plane. Cos we know it's not everytime the case
I flew mine and the CG location is correct. I use Lander 90mm 1750 KV metal fan sold here, 80A Hobbywing ESC. I use both 4000mAH 6S 45C Turnigy Nanotech and 4500mAH 6S 65C Genesis Lipo to fly it. Just slide further to the back as you are using heavier battery. I plan to use 5000mAH 6S 65C Nanotech this weekend and slide the battery all the way to the back. You need to add a 2 inch long and 1/2 an inch thick foam on the rear of the battery compartment so the battery can sit properly. Man, this thing flies awesome and extremely fast with this setup. Make sure you use good electronics as once you glue on the wing, you can no longer access the ESC and the wire extension to servos and servoless retract without cutting. Check everything and make sure everything is working before glue on the wing
What a great and complete answer EDF Freak!! I use 5000 mah Nano Tech 25-50C, because of the weight you can safe with this battery... And Yes, it makes the plane take off at very high speed because of the cg... And I think that sliding the battery all the way back in maybe not suffisiant...
My combo is a 200A ESC (security) with included 5A bec, and I use the 5 blades High Torque EDF to have A ratio Thrust/Weight around one.
Nice combo for great plane
Just go to the page where this plane is displayed and scroll a bit down to see the recommended items to be bought with this plane and you will find the recommended retract. The retract cost USD 7.19 each if you buy it separately
fg fuse and paint would weigh be heavy for this already portly looking jet :) you'll find you have to dump some good power just to keep up from being embarassingly slow. but even as a foamy it has striking looks and nice/light wing loading. I put a coat of clear on my 70mm version and it looks just as good 1yr later. very stable edf
Thanks for pointing that out. Good to know. But yes, I did "read" the entire description and the material was not to be found in the worded description. This is a departure from the typical HK description. I'll look at the icons more closely in the future.
I have the PNP version, and it flies very nicely, even on the cheap-and-cheerful Chinese electronics. Radar says 150 kph on the 6S system. The main gear swings ou at 45 degrees from the fuse, so you'd need to fit a good strong set. I filled in the voids, fitted ply skids and bungee launch mine. Flaps don't seem to do a lot. Stiffen the elevators if you're going above 6S.
