Hey all, just finished buliding up my Hanger 9 Alpha 40 ARF. What a sweet looking plane!
The parts list is as follows:

OS .46AX engine
11x4 prop
4 hitec standard servos
Hitec Electron 6 rx
Optic 6 radio w/synthisized module
and a 5 cell 1050mah rx pack
I cant wait to hear the engine run. I'm going to Break it in today and off to the club tomorrow for some lessons[8D]

P.S. What kind of prop should I use normally? I have a G/F 3 Series Master Airscrew 11x6 prop that the guy at the hobby shop said to put it on after I have broken in my engine. would this be OK or would a 12x4 or a 12x6 be better?

heres some pictures...

Happy flying

To me, the 11x6 is the best all around prop for a .46 BB engine. The 12 X 4 would be ok, and would slow your plane down some--which may be desireable while learning. I'm fairly sure the 12 X 6 would be way too much prop for the .46. The 12 X 4 is pushing it, but some of the stronger .46's (i.e. the AX) can handle it ok. Just may sure you tach it and aren't loading the engine too much.

I have the .46 AX as well on my LT-40. It turned an 11x5 at around 13k. The instructor said that it'd be better to run around 10k at full throttle so maybe look at a 12x5 or even a 12x6. For the mean time I put on my 11x6.

Good luck!

Congrats Adr ian64. You'll like the Alpha.

I'd go with the 11x6 as a good combination and also just a tad more ground clearance than the 12 especially if on grass.

Otherwise a good looking trainer combo. I've trained several on Alpha's and they fly well.

Good luck.

I actually found that a 11-5 works better for trainers. It allows the engine to rev up quicker and gives you extra pull when you need it. For training I would stick with Master Airscrew props. They handle grass bumps pretty well with out breaking (most of the time).

I'd recommend an 11x5 also, but an 11x6 will work.

You'll love the Alpha, it's a great little airplane!

I have the Alpha 40 RTF with the evolution engine and am running a 11X7 prop. Gives it a huge boost in power, I think it performs better than the 11X6. I have tried the 11X6,7,9 and so far 7 gives me the best performance. My opinion only of course.
Welcome to the ranks of the Alphas!

Ya have to remember mazer, we're talking about a beginner here. Speed and performance is not the issue. He needs to be able to accelerate up and out of the grass quickly and PUTT about the sky learning how to fly and then slow the plane down to land.

LATER he can perk up the performance a bit.

Hi all, I went to the field on Sunday and all I can say is wow. Broke her in on the ground for one tank then let my instructor take her up. She needed some down Elevator trim and a few clicks of rudder but flew very straight. Since I couldn't fly yet (still waiting for a confirmation from MAAC) my instructor tested everything out. He stalled it acouple of times, told me to move the battery forward by the tank. Then he let her rip! before hand he told me to get rid of the 11x4 and put on the 11x6 that i had, he was pulling loops at 1/2 throttle.[X(] He tested out the roll rate said it was fine. stall turns were good, inverted was a little weak(but what do you expect for a flat bottom wing) flat spins[X(] wow what a rush. After that he kind of walked me threw a rectangle type landing, little flar at the end and a very cool 3 point landing just as it ran out of gas. What a cool airplane, and to think I was almost going to buy a 1/2a to learn on. The field experience and the bigger plane make for way more fun.
I'm also very happy with my OS .46AX. Once broken in, it only took one flip to start it up and wow, what a sound at full throttle.

My MAAC should be confirmed next weekend so I can finally get a chance to fly!!


Thanks all

Great news. Your plane is a much better choice than a 1/2A for training, so much easier to see and a lot more stable in flight. Add in the great engine sound instead of the whine of the 1/2A and what could be better?

Congrats on the planes great performance. You should be able to fly any way. If I read the MAAC rules right, when training, the instructor is the one that is responsible for the plane and he's the one that needs insurance.

According to tower, max HP is gained at 16,000 RPM on the .46 AX. If you prop it so that the max RPM is 10,000--you are severly overworking that engine, and you are going to have heat issues and loss of useable life on that engine. Prop it so that you can get at least close to 15,000 RPM, if not the full 16,000. I'd imagine that engine could turn an 11x6 at close to 15,000 RPM once tuned properly. Then, if you only want to run it at 10,000 RPM, use throttle management. This will make life much easier on you engine, and your investment will last much longer.

I got this trainer for my 2 sons. I just got the ARF version and put a TT Pro 46 and Hitec radio equipment in it. It lfys great! I like to fly it because it flys so well. It beats the heck out of the Nexstar trainer. All the trainers at our field agree on that!

Good Luck
