Looks like a soft cutoff as you still had idle. When I flew my Heli with A123s I just removed the cutoff voltage and timed my flight. A123s are good , will you be able to incorporate 10s2p on the LA7?

can't go 10S2P since that will go over the 50v ESC limit but I could do 14S. I will see what kind of performance I get before moving to four more cells. I don't think I ''over-amp'd'' the ESC as the watt meter shows 45 amps at full throttle...this is an 85HV ESC. I am not sure why it cut out at the field but on two sunsequent runs when I got home, I had no issues at all. Now, I need to get a spinner from Tomas. I sent him an email but no answer

You can go 10s 2p but run then in pararellel. Not in series. It will give you the same voltage but twice the run time. That is what I did on my Wellington.
If you would just up your cells by 2 you would see a hugh difference in your power...

RE: ESM LA-7 From VQ Warbirds
I just messed up the right wing wheel well liner trimmed it too close to the opening. I can probably repair the gaps with ply or flightskin, but would really like to have a second shot with a new liner. Does anyone have a liner that they aren't going to use? Please email me at [email protected] maybe we can make a deal. Thanks...

RE: ESM LA-7 From VQ Warbirds
Thanks Ty,
I was able to make my mistake work. It will take a little bit of hole filling with a couple little pieces of Flightskin, but will work and look fine. Good thing it is on the bottom of the wing so I don't have to look at it all the time. The retracts drop into this thing like nothing. Has anyone had any issues with the rails not holding well. I did have to put a couple of spacers in the leading edge side of the rail to level it up but it doesn't seem like there is much that the mounting screws are going into. Which is fine because I plan to grease the landing every single time.

If anyone is interested, I bought the ESM retract set for the LA-7. Since then, Bruce at CJM made me a set for my ESM LA-7. I intend to keep the wheels and I would like to sell just the retracts and air kit if someone would like to have a set or an extra set. Contact me if interested.

Having more cell count (higher voltage) would require less amp for the same needed result you had with 10s. The 80HV will run cooler than before.

I am no expert but have gone through it with my 3D helis. Higher voltage can mean higher efficiency while extending the life of your batteries. How many minutes of flight time are you getting on the A123? I ran a 10sA123 on a heli and I get around 4 min max at full power, drawing 2200 from the packs. A123s are great but Lipo is still king when it comes to power and weight. I rebuilt all my A123s to RX packs and they are working great on my warbirds.

I understand about the Lipo's. I didn't want to worry about the over-charge, discharge, volatility and generally slow recharge times. Plus, I would have to design an easy-to-access hatch for removal of Lipo packs and I would have to haul around several packs to get several flights in at the field without burning up the entire day. The A123's allow me to re-charge the packs in the plane over the course of about 35 minutes so I can get a couple of flights every hour. I usually don't fly more than a couple of hours anyway so four flights works just fine for me.

My LA-7 has arrived today. I plan on fitting Ty's spinner and cockpit along with a gas engine. The engine hasn't been chosen yet (plenty of time to save for that) but I would appreciate any suggestions from those running gasser engines.

I too look forward to a report from someone flying a gasser in this plane. My experience (when doing a wing repair) is that the structure is extremely light and easy to break the glue bonds. I wonder what the vibration would do??

Last night a friend suggested that I should use the 1.80 four stroke I have sitting in a box. It makes sense to use what I have (save some dollars) and the kit does specify a 1.80. Has anyone tried this engine combo before?

RE: ESM LA-7 From VQ Warbirds
My other (off the shelf) engine choice is a YS120NC. While it may not be quite the thumper a 1.80 should be, do you think it'll be enough?
