Default Anyone have the SAB Havok or Drake?

I have the kraken helicopter, and if the jets are half the quality of the heli kit, it will be outstanding. Anyone building one? Huge fuel tank, curious if there is room for smoke? the machining and anodizing on the heli is the best I've seen. And SAB has been doing carbon blades for 20+ years... they know composite. Looks are up for debate, I'm interested due to perceived/hopeful quality of kit....

There are a couple being built in eastern Canada. I have been skimming the build thread on rccanada. They look good outside of crappy screws which both builders are talking about the screw heads shearing off while attaching servo covers. Easy to deal with I guess, just personally i always feel uneasy when quality hardware can't even be supplied.

I understand the early ones were moulded in the Far East, the Havok I flew flies OK, but wing loading means the landing needs to be relatively fast and there is a critical AOA, if you increase it to flare hard the lift goes. If it was lighter it would be better. Not sure of the weight but for the size it feels weighty when you lift it. When the nose door is open it acts like a turning vane, so you have to turn finals using the rudders.

I am curious, are the later versions lighter and fly better? I have seen video of the Boissan brothers and the jets come in very slow for landing, I am interested on buying one from a fellow flier but I am not sure if this is a jet to have fun and relax or a jet that wants to constantly bite you, I have to make a decision soon on the Havoc.

I built the havok and Drake, amazing quality, true ARF's. I flew the drake ten times. Just never got a good groove with it. It felt heavy. Flew more like a scale jet than a sport jet. I had a 210 in it and the smoke tank pod. I think a smaller turbine and less gas on board could make a difference. It could really use a speed brake as well... lands hot. I experimented with deflection gate canards ala rookie.... didn't work. Just a gorgeous kit and great quality! Just didn't fit with my flying style...

There is a later kit in my local club, it is lighter than the original but still has to land relatively fast. If you can get the AOA at the perfect angle it touches down quite nicely. But few degrees nose up the speed bleeds fast and it pancakes. A degree nose down and it descends quickly. The nose unit has broken out of this aeroplane every flying session. The owner has decided to sell it as he wants a short strip model and this isn’t. He concluded you need tarmac. I’m sure after lots of flights you can get dialled in to it’s characteristics like the brothers.

I wanted to get one the day I saw it......for 2 reasons, The model has quite an orignal design that appeal to me, and I have own many SAB Heli and they were all great so...I taught the Plane would be great as well....got one of the first In North America.....put all the best in it....with a K210.

At first I was like geez this nose section is so heavy with the unknown amount of lead the factory put in it.....build it like the instruction said and place as much forward as possible....did the CG and had to put even more lead into the nose....??

The fuse is now broken just half of the split.......not sure if I will ever fix it, or get another fuselage......it was flying fine...but I think the jet is just too heavy, because of god knows how much lead there’s in that nose...I added 336gr....to the big chunk...also run 4 batteries (needed the weight anyway)

I have the Drake that Dr. Scoles built.

Balanced it as per the manual and have to agree with everyone that it flew as if it was VERY nose heavy.

I had placed two(2) 3,200 mAh Venom hardcase LiPo receiver batteries ahead of the nose gear wheel well, the ECU battery and an 1,800 mAh battery for the gear just behind the nose gear wheel well.

The Powerpack for the JC Cheetah was installed under the rear equipment tray and the UAT was placed under the forward equipment tray.

I used a Xicoy LGC-15 controller for the gear and brakes to have more control over the braking.

The Drake balanced exactly where the manual showed.

As you can see in the photos I have switched to smaller (lighter) batteries, except for the ECU battery and moved all the batteries as far back as possible. I have also placed 6 oz of weight near the motor.

The Drake now balances 2 inches further back than what the manual shows and is just slightly nose heavy. The thrust vectoring now has more authority than the first flights even though I only have a 36 lb thrust motor.

It flies well, is very stable and when I slow it until it stalls the plane starts to mush and then the nose gently falls with the wings remaining level.

I use both rudders as airbrakes and it slows the plane up a bit but also keeps the nose up in a good attitude for landing.

I flies a lot like my C-ARF Rookie and am really pleased with it.

We recently had a giant Warbird event at my club and after I explained that the Drake was a Warbird from the future, they were gracious enough to let me fly.

Great to hear Lee. I bet my landing woes were that it was too nose heavy. I honestly never messed with the CG. And I agree, very much like the Rookie, I had two of them... But, with the rookie, you could mix the canards to go 80 degrees and land it like a foamie...... I tried mixing with the canards on the drake, and it did not go well LOL

Glad you are happy with it!

Where did you get the wing bags for the Canards?
Thanks,

They were canard covers that I had left from a Rookie.
I cut them down to fit the Drake canards and added the strap to hold them in place.

Sorry it took so long to respond but I don't check this forum much.
