Yeah, I can fly...

Well, my first maiden attempt resulted in a long run off the end of the runway even though I cut the power early. Tore the stock gear nose and one main gear out

I think it was still too nose heavy and thus collapsed the nose gear so much it stuck to the ground despite full up at full power after a few second.

So... I am making the following changes:

E-flite 15-25 retracts all the way around. I had a double wheel nose from an F/A-18 using stock tires. Mains will also get bigger tires. This should cover and takeoff/landing issues.

Switching to a 5s 4200 45c setup for power. Running a 2s 4200 45c and a 3s 4200 45c(Hyperion) in series. 3s pack under the hump and 2s laying flat under canopy area. Should put my balance further back.

Remember, I'm not running the stock motors, I have 3000kv 5s capable motors.

Rain has been a factor for the event I finished for so I may make an attempt to fly it tomorrow

You may want to check your AOA while on the ground as well and ensure you have a slight nose up attitude. Also ensure tail is set up right. If I remember correctly they were set with a bit of up in the neutral position. Not sure of your power setup but one thing to remember is that going to a 5s setup will noticeably dercrease power/thrust output. Here is one pic of elevator neutral position

The new nose gear is set for a little more up than before. I have a little up already on the elevator, it was real close the last time so I think I will be good.

This was built from the ground up- i.e. NOT using the 2100kv motors that it usually comes with. I opted for Dynam 3000kv's that usually come with the Meteor. We have run these as 5s in other 70mm airframes with great success and I thought two would be enough for this.

Same happened with my F-16 until I raised the front LG 1.5cm.

I will try and come back here and do that again later this week. Thank you for the compliment.

For now, there are pictures of them on my blog page you can study to see how I did it, plus several modifications

I finally got mine up on the 3rd attempt. Needed a significant amount of up trim. One of the fan covers came off in flight but was recovered. Luckily the fan did not come out! I was amazed how much she wanted to float on landing, I had to go around and greased the landing. She flew quite well, didn't get to try the flaps/slats or drag chute yet. I started a new job so I've been rather busy so have not flown it again yet. I plan to add the gear doors but will probably fly it again soon. Glad to be part of the club flying this awesome bird.

Starting my replacement mig build. Had the green version stock before and liked the flights so went with the gray version this time and the cs12 blade fan system that I am starting to put in most of my planes.

Thank you


It's a fun edf and I see it (in the air) better than my f-18, something about the tail fins. I've only got a 7 channel radio, what are you vectored thrust guys using for radios on this plane?
