I don't have one but the results of a quick search suggests the HiTec H4 supports Li-Fe charging so you should be good to go.

Yup, I looked too, and the manual is saying you can. Here's a link to the charger I looked at, and there's a link to download the manual on that same page. Start reading at page 15 or so there....

I love my Hitec X4 charger. I even charged a large car battery with mine a while back. (A full size "real" car battery!)

I have one of the H4 and its the ducks guts . Although Im not a serious electric flier so it may have some limitations for those with big packs to charge . The above link is the same as mine but they have an updated one with some pretty red trim and improved specs and features I think but not %100 sure .

Got it figured out. I have the older version of the H4 and was able to find the manual.

Thanks Guys

I have the same one and use it on LiFe batts all the time . I like this charger .

Mine has a DLE 40-twin, Smart-Fly power expander, three 2100 mah LiFe batteries, Savox 1258's all around (except for throttle). Smart-Fly Power-Expander, pin/flag fail-safe switch. Elevator servos in the tail with an all-up weight of 14lbs 8 oz. Flies like a dream.

Anyone setup this plane on a Futaba 8fg?

Red Beers

Update...about 3/4 finished, should have it done this weekend.

Question, the kit came with a metal push rod for the throttle. Should I change it out to a plastic one or will the 2.4 frequency be OK with metal?

Having a metal pushrod will cause no problems wether you are on 72 or 2.4. The important thing is to ensure that there are no metal to metal connections to the throttle as that could cause a radio interference problem.

rightflyer

Always use a nylon clevis or a ball link to isolate the metal rod. no problems experiecned with interference.

Red Beers

Thanks guys. Ball link it is.

One thing I have found after about a half-dozen flights, there is little prop-clearance, even when flying with a 19X8 prop. Came across a slight bump in my field (on a very smooth landing) and it caused enough of a bounce (the tires did not even leave the ground) and it destroyed the propeller. Also, be sure to double-check and add some epoxy to the aileron/flap servo mounts in the wing (as the instructions tell you). After a prop-strike, I had a flap servo mount break loose from its cover plate. Going to go over each one and add a little epoxy to strengthen all of them.

Red Beers

Thanks Planejaw, will do.

rightflyer

Thanks for the heads up. Were you using the stock wheels? What size wheels are you looking at now?

I heard about the servo mounts and put some epoxy on the servo mount surface, but the mounts seemed very tight. I wasn't about to try to remove them and re-glue. I would have preferred if they left the modeler glue them in.

I finished the airplane yesterday. It balanced perfectly with no additional weight (not at first of course, but after hours of modifications). What I did was open up the area for the fuel tank so it would sit on the bottom of the fuselage. I reinforced the balsa on the bottom with popsicle sticks. Then I built a shelf above the fuel tank to hold the ignition (front) then two A123 2500 mah batteries just behind the ignition. All 3 fit under the magnetic hatch.

I used the Hitech D645MW servos, Aero-Tech bec, and two Rexcel switches. All of these parts were suggested in this thread.

Thanks to all the guys who helped advise me of the latest and greatest parts and ideas. I'll report in after the Maiden...hopefully sometime this week.

Yes, using stock tires and wheel pants. I think I'll leave them as is because using larger tires will not allow you to use the stock wheel pants. I'll just have to make sure I'm landing on a very smooth part of the runway.

With mounting the two elevator servos in the tail (due to having the DLE-40 twin in the nose), I am using three 2100 mah LiFe batts mounted right under the leading edge of the wing, then mounted the Electronic Ignition Box on the underside of the hatch over the fuel compartment. Works very well, balance is perfect. I'm also using a Smart-Fly Sport Plus with ignition, which is one reason the weight, without fuel, is around 14 lbs, 7 oz.

You can always rebend / recamber the gear a bit and gain quite a bit of additional clearance.

Red Beers

Well the maiden went good!!!!!!!! Need to tweak a few things, as always. New question, I'm using LiFe batteries and voltage is 6.6 to 7.2. My throttle servo is one that I had on hand, a JR Sport ST47 I also have JR sport 125MG, do I need a voltage regulator for those or should I upgrade the servo?

Red

the pope

should be fine . anything rated for 6v will handle a LiFe battery

Planejaw

My Feedback: (53)

Agree on not needing a regulator for LiFe batteries. I've been using JR, Savox and Align servos for years without a regulator and they work fine with no ill effects.

Red Beers

Thanks gents. Back to the field...

Red Beers

OK after the second day of flying (the first doesn't count because of nerves LOL) it seems I'm might be flying quite nose heavy. Yes it balanced at 4 1/2 on the wing but when I cut the power for landing the nose drops to a 45 degree angle after the speed bleeds off. This actually sets me up perfect because I'm always high on my approach (depth perception issue) and when I'm 6 feet or so off the ground I level out. The speed bleeds off quickly and I can grease it on. So far I'm landing without flaps. There's no float to this plane. Is this just the characteristics of this plane or are there adjustments to be made?

The more I think about it this might not be a bad deal. I have been flying electrics for so long...chop the power and land. Maybe I now have and airplane that you need to fly it onto the deck. Hum!
