Just a couple more observations:

It looks like it will be closer to balanced with the 2100 mAH battery. It is tail heavy with the 1500.

The gear struts are not very good. I was installing the battery and I put a little pressure on one and it just snapped off. It just glued right back on. I had actually considered leaving them off. The wings struts are fine, as they are screwed in.

Great job on the build photos (especially this one!).

Can't wait to hear about the maiden. Any chance for video?

Sorry, no video. My buddy who usually brings the video camera decided not to show!

I will post pics and give a review in a little while.

Default Maiden Flight Report

Realizing I have flown very little this year, since I have been focusing on getting the business up and running, I let my friend takeoff and trim it out for me before handing me the controls. We only needed a little down trim to keep it flying level at the desired cruising speed, but probably did not even need to trim the plane.

This is a very stable flyer! While Cubs are not typically considered good trainers, this was extremely stable, with good self correcting tendancies and would not be bad at all as a trainer. Very smooth and very easy to fly. It also had good stall charateristics. The Cub taxied over the (very short) grass runway without a problem. It has the same size wheels as the Hyperion P-51, which also flies great off of this runway, but had troubles at a runway with longer grass. So I would recommend short grass or smooth surface.

The Hyperion 16C 2100mAh battery was perfect for balancing the plane, but was almost as far forward as we could get it. The 1500 would be lighter, but you might have to add a little balast to the nose to balance get the right CG. I did not time it, but I believe we flew for 8-10 minutes and still had 11.5v left on the battery, so you will get excellent flight times with the 2100 under normal flying. I don't think we flew it much at more than half throttle.

This is nice, easy flying plane and looks great. I would highly recommend this kit (and not just because I sell them). I don't think you would be dissapointed. I don't know that it would be a great first plane, but maybe a second plane and/or aileron trainer, it would be perfect.

Sorry, I meant to get the AUW, but my buddy forgot his scale. I really need to get a new one! I will either borrow or buy one early next week and report back.

Super report Chris, Now I'm really looking forward to getting mine airborne.
Is it possible to use slightly bigger wheels to be able to take off not only from "greens", it irritates the local golfers when I do

Yes, you could easily use bigger wheels.

With the recommended Hyperion 11.1V 1500mAh 20C Lipo: 26.3 oz
Plane without battery: 22.0 oz

Note: Both batteries had Deans Ultra connectors.

I think I mentioed this earlier, but the 2100mAh battery got was the closest to the proper CG. With the recommended 1500 and a Tanic 1550, the model was tail heavy.

Thanks Chris, then I'll order some so I can use the same grass field I use for helis. Great that it balances well with the 2100 pack as I have 4 from my TRex that I then can use.

Started building yesterday. Got the ailerons in place as well as aileron servos.

Looks like it's gonna be a great littel machine

Hi guys Just thought I'd pop in on this thread. Really great. I'm just finishing up my build of the Cub,should maiden it this weekend(weather permitting). The bottom line is the overall appearance and of course the flying characteristics of the Cub. Should be, by all accounts, a gentle flyer and a lot of fun. It will be a welcome change for me as I'm now flying the Ultrafly Ultimate bipe and the Katana Mini( you really have to stay on the sticks with thiese birds).I bought the Hyperion Cub because I've always loved the classic lines of a cub and this one just fit the bill. I've been following this thread and can say how much it has incurrouged me to first buy and build this guy. Looking forward to a "change of pace" flying. Will try to post some pictures (just sold my digital camera and am in the processes of ordering another ) as soon as possible. Once again ,thanks for a great build thread.

Good luck with your maiden. I think you will like the change of pace, as it is a really gently flyer.

I just know if he does that, I'll pitch it into the ground and have to do the "repair thread". Its one of those Murphy's Law things!:o

Hi guys Well I was able to get in a few flights this morning at the local school I fly at. Maiden flight was hairy,she rolled severly to the left on lift off.I was able to gain control with a lot of right rudder and got her up to where I trimmed it out. Nice and steady,a pleasure to fly. I noticed she still rolled to the left when power was applied,and it accured to me that there was'nt any right or down thrust built in to the motor mount. I'm using the Ultrafly FRIO 10 which is rated at about 150 watts,so it's diffinitely torgue causing the problem. I'll try shimming the motor to get some right and down thrust dialed in. I'll see if I can get back out tomorrow and see how it goes.I figured I'd just mention the "thrust problem" for what it's worth. Maybe anyone who's still in the building stage may want to look at this.

I maidened my cub today with no alteration to the motor mount. ROG fairly straight and only needed couple of cliks of down to trim straight and level at half throttle.

This is the first "wooden" ARF I have built and was quite dissapointed given Hyperion's excellent reputation. In particular-

1) Poor covering - many wrinkles and loose covering.
2) Contol wire too small in diameter compared to the hole diameter of the supplied horns - creates control slack. I used proper sized snap links the and cyanoed the supplied wire to the links after cutting off the z bends and bending on itself.
3) The rudder and elevator screws are too long and no safety back plate is supplied. I discarded them and used horns with bolts and backplates for security reasons.
4) Only 2, not 4 wheel collets supplied.
5) One servo mounting back support piece fell off whilst light trimming to size.
6) Wing mounting holes out by about 2-3 mm.
7) No mention of dihedral brace to be fitted one way only. May cause beginner to glue up wing incorrectly. Also obsure that epoxy is needed on brace as well as ribs.
8) No mention of air cooling entry and exit holes.
9) Battery hatch too long to fit nicely.
10) I will think of no 10 later!!!!

But it did fly straigth and true with no vices obvious on first flight.
