Mine got Hammered and Hog'd out from some Gravel Strip Operations. Always had to mess with them. The Struts are rather Long and with the aircraft weight, I find keeping all the Landing Gear Parts together and Tight a real challenge on this one. I've purchased 'Spares' for the NoseGear stuff but honestly, the Mains could use a different Strut assembly (More Robust). One of these days I'll get around to it. GL

Originally posted by apmech1 View PostDid my maiden and second flight. All I have to say is wow. This plane flies so well! Stock 6s setup. It seems to have gobs of power. As everyone else has pointed out the roll rate is crazy. I got video with my soloshot 3. No aerobatics, just bomber patterns so far.

Good stuff! Which packs were you using and what are your settings?
Cg was where the manual called for 180. All controlls were low rate, 75% of manual full deflection. I was using 50 % expo. . I am going to move ailerons down to 60% throw and decrease all expo to 35%.

Hi Guys,
This winter I built many of my MRC airplanes and the A4 was one of the first projects. So much fun to build and the waterslide decals (lots of them) were easy to work with. Actually I have not applied waterslide decals in a long time. nice plane to build and went together easily.
So today, I did the maiden flight using my Thunder power 5000 6S packs which are about 60 to 90grams heavier than the MRC new Admiral batteries. I put the pack back 1/4" behind the front edge of the plywood that gave me the CG slightly aft of the normal call out.
The plane flew beautifully on low rates with lots of power. very agile and quick to turn. Rolls were fast and predictable. Full flap landings were spot on with high Alpha flares. So much fun and reminds me of my old Byron Originals A4 just slightly smaller scale. Great plane and good job by MRC and Alpha to bring this plane to us with great scale fidelity. One of the club members shot some videos of my flights but I did not get them yet. Hopefully I will post them once I see them for myself :)
I highly recommend this jet to anyone with some EDF flying time

I agree this jet will be one of my favorites..... I flew my L39 first after reading all of the hype and watching the videos. Yes the L39 flies great too, but the A4 is sweet and agile
All the best

(With the original throws, mine was sensitive as hell and rolled so fast it was like a freaking drill bit - and after about 3 or 4 revs it actually induced a snap roll! Or that may have been because I touched the elevator :Cool:)Marc flies FW & FL: AL37, MiG-29, T45,F4, A4, A10, F104 70 and 90, P38, Dauntless SBD, Corsair, B17, B24, B26 & P61, Lipp.P19, ME262, Komets, Vampire, SeaVixen, FMS Tigercat, FOX Glider & Radian XL.
