Hi Pete

Well, I've only flown mine once with a standard mix. So, I can't really comment about acrobatics yet. But, I am building a mix with flaperons just for fun. And, since there are two servos for the elevators I've thought about mixing in some elevons as well. But, I'm not sure the plane really needs them. The control throws are pretty large as is, and she rolls pretty sharply stock.

Hi Todd,
thank you for your reply.

I was thinking of adding elevator to help the rolls but she rolls pretty well stock as you say. That's why I came and ask, to see if anyone noticed any improvement by mixing up anything.
I was also thinking of putting ailerons helping elevators to help on loops but I really don't know if there would be any improvement with that kind of mix.
Has anyone tried any of these mixes?

Thank you.

Hmmm.... that is an interesting idea. Not sure how that would turn out. Could be an interesting experiment.

Weather here sucked all weekend, so I didn't get a chance to try anything new. Gonna be crappy weather all week too. ARGH!!!

Finally got another flight on this baby today. Weather was beautiful this morning. This bird is a lot of fun to fly. Just goes right where you point it. I like that.

Mine has flown once since last post but it was so windy that after landing a gust of crosswind flipped it upside down while taxiing!
What batteries are you using? I have a 2600mah 30c GensAce and a 2450 30C Turnigy, and keeping on the safe side, can fly roughly for 4m20s each. How about you?
I'm thinking of getting a "bigger" battery (3.0 or 3.3) so I can get more fun time out of it but don't know how the plane will behave with the extra weight since it's already nose heavy. Some input on this is greatly appreciated.

Dang, that's pretty windy. I hope not much damage was done.

I'm flying on a 2650mAh 30C Blue Lipo. I can get about five minutes out of it with a mix of full throttle and cruising at 50%. It comes down with about 40% remaining. I have a 3300mAh, but I can't get it to balance at all with that in there. The intake ducts don't allow me to push it back far enough. I've thought about adding some weight in the tail under the vertical stab. I'm sure the plane can handle a little extra weight.

Sunday was a black day for my AJ. Due to a fragile way of securing the Lipo in place my plane crashed to the ground uncontrolled.

I was actually recording the flight with a HK wing cam and you can see the video of the full flight and recovery here ->

AlphaJet Crash (4 min 8 sec)


I picked up every piece of it and it lays currently on my dining room table waiting further repairs.

That sucks Pete! Sadly mine suffered a similar fate just two weeks ago. However, in my case it was my own stupidity that dumb thumbed it straight into the ground at full throttle. Everything smashed right up to the intakes. Lots of tiny, mangled bits. And, there don't seem to be any replacement parts anywhere. I may have to buy a whole new plane. I really liked how if flew.

I hope you get yours back together soon.

Hey Todd!

Tough luck on that one... :/

Mine is in pieces also right up to the intakes and the parts where all shrunk and twisted.
But if you put each peace of the foam in boiling water for a few seconds they'll get back to its original form and it makes recovery so much easier!

I haven't searched in the US for spares but I managed to find a few stores in the UK and Germany where they sell all spares for our planes. And I do mean all! Decals, nose cone, fuse, wings, stabilizers... the full monty!
Try to search the US for FMS FS-FA101 which is the part number for the fuselage and FS-FA304 which is the nose cone (or cowl).
In the UK they're not cheap, around 50 + shipment for the fuse only, which is about half the price of the full plane with electronics, but if you can't repair the one you crashed and you're trying to keep repair expenses to a minimum it can be a fairly decent option.

I'll keep you informed on the progress of my repair.

Here is a pic of the puzzle I made for myself

Hi Pete,

OUCH!! That looks terrible. Mine is about the same, except for the chunk you have on the right side. It's all gone on mine. I've tried to resurrect the twisted pieces, but it isn't looking good. I'll look into the off-shore supplier options. Thanks. And, good luck getting your's back together. I look forward to your reports.

O.k., good news for me!

The repair is going very well and I'm almost ready to fly my baby again!
After I re-expanded all the foam in boiling water I started gluing all the pieces together with very good results I believe. It's not going to be as beautiful as it was since all the joints will be very visible, but,most importantly, it will fly!

Since I was already repairing th model I took the time to add a place for an extra servo for a rudder that I'll be installing. You can see it being tested for fitting in the photo.

This is the status quo of the repairing process.
I think it will be over this weekend.

How is yours Todd?

That looks pretty darn good Pete! Looks pretty straight in the photo. Good luck with the re-maiden.

I haven't had the opportunity in the last week to get anything done in the shop. It's been one of those homelife weeks.

Hi Todd,

almost done with it. Here are some pics for you to get inspired.
I'm in a hurry so I can't write much.
Enjoy...

Looks pretty good for having been smashed to little bits. I like the carbon fiber frames you've got in there as well.

How did you hinge the rudder?

Hi Pete and Todd

Did exactly the same thing to my 90mm Alpha Jet last year - complete re-kit.

It's amazing what a little epoxy, microballoons and plywood can do. Mine has now had well over a hunderd flights since the re-build, and it still flies like it's on rails. I took the damaged retracts out and filled the voids instead of replacing them - saved weight. I now bungee launch from ground and belly land on plywood skids that I fitted.

I may even get around to repainting it one day, but I'm too busy flying it for now
