Status: offline 		While I don't have a Diamonte, I do have a Vanquish. For batteries, I'm using Hexatronic 2200 4S packs. They are 20-30C and claim that they are good for 35C. I got them from United Hobbies in China for $38.95! They are well made packs with a balancer tap that fits the Hyperion Balancer. The shipping was $11.55 for 2 packs. I have since ordered 2 more. The down side is that they take a month to get them if they are in stock. Suggest the courier service if you need them faster.

Wow, hello Dick Hanson! I sure did enjoy your columns in Model Builder! In fact, I have a set of plans for the "Runaround" that I believe would make an excellent electric pattern airplane. Your preaching about building light sure has come to pass, hasn't it?

make absolute sense to me!

Any pics or how-to instructions? I'd be interested to modify it.

Status: offline 		Frank -- I have not looked into those cells - yet -let me know how they pan out.
The wire gear -- this is an old art form and likely someone you know has a wire bender ( ask a granpa)
The best setup simply duplicates the setup on old trainer mains such as the Sig kits used. across the bottom of the fuselage --then up the inside . in a channel made from two ply wood or spruce sticks .
the screws on the bottom now simply attach nylon straps - to hold wire in position----all available in any hobby store.
two pieces of wire are used -- 1/8" dia is right for this model and even smaller if you have a really smooth field
also FOX made some wire gear wheel pant attachment devices which slide on and align as you like by tightening a set screw clamp .
It isn't hard to do and it all is faaaaaar more forgiving than rigid al or carbon fibre gear .
oh yeh -light too but don' tell --

Status: offline 		Thanks lthibault for your reply. I was inquiring out of curiousity but now out of necessity. I took the plane up on my first windless day for a couple of flights. The first landing from a
shallow dive went well even though it was faster than normal due to no headwind. - No problem. On the second landing I decided to make my approach flat and from further out. Problem was that from that range out I could not easily judge my speed and ended up stalling the plane from about 15 feet above the ground. I recovered and set the plane down on the right gear first. I rolled along for less than a couple seconds before the gear tore free followed by the left gear a few feet later... No a particulary hard landing, just not balanced. No other damage was suffered outside of ripping the gear support out of the paper thin balsa buttom.

Question, did you construct a top and bottom in addition to the four sides that you mentioned above? I have already begun construction / repair on my plane.

After only six flights and two LG failures, I can say this... The plane is fun to "fly" and frightining to land while worrying about the egg shell bottom.

I let the techs know at e-Flight, the tech said that this was the first he as heard of the problem with this plane... I told him to check around on the fourms.

Second, have you noticed any wired medium to slow speed handeling characteristics with his plane? With only six short flights to date, I can't put my finger on it but the plane (while balanced to specs at 5.5", it seems a bit nose heavy). Ofcourse, balance will soon change anyway.

Thanks again for your time!

Status: offline 		Concerning the new bottom I didn't put anything on top, just four 1/2'' by 1'' pieces on each side of the plywood used to replace the bottom.

Unfortunately the weather is been a little hectic here (very windy + snow ) so I'll need to make more flights before I can comment. From what I can remember I have the same observations: the plane is fun to fly, it won't slow down very easily but I think it's a matter of getting use to it and practice stalls at high altitude.

Status: offline 		Now that I've solved the landing gear issue I was able to make a few flights today.

All I can say is thumbs up, the plane flies very well, crisp and responsive. I had to use a lot of exponential to reduce the throws, they were too much for me.

I'm currently studying her flying patterns, just practicing take-off and landings, basic acrobatics.

At this point I would only make one recommendation: don't cut power and let her float while landing, keep some throttle and be ready to increase power if necessary as she might fall very quickly depending on the altitude and the wind.

Status: offline 		Thanks again lthibault for your suggestions. I have completed my modifications and now have several days of flying and landing under my belt.



The plane flies great even with the additional 47 grams that were added to the nose. I was able to rebalance the plane by moving the the 5000mhA battery to the backmost position.

For the fun of it and extra cooling for the speed control while flying on hot Arizona days, I cut and screened in a NACA duct in the lower cowl.


Because of the short approach and short LZ at my favorite grass field, I still wanted to slow the plane's landing speed so I replaced the aleron Y cable with two direct aleron cables (plugged into Ch2 and Ch6 on the Rx) and programmed my JR9303 TX to drop both alerons (now flaperons) about a 1/4 in. while automatically adding about 1/8 in. of down elevator at the same time. I have timmed the deployment to take two seconds once the flap switch is hit...

Flaperons on this plane work great slowing the plane on final 5~7mph while still tracking straight and level. I do need to "fly" it to the ground because in really wants to float once it enters ground effects. Also, I deploy falperons at a medium speed... I tried it at a high speed and the plane wanted to climb.

For any interested parties, the Power 32 with CC60 Esc, 13x6.5 APC prop and fully charged 4S 5000mhA battery bench test on Eagle Systems Micro Logger at the following rates...
Instant Max Throttle: 62 amp burst (lasting less than a second)
1/4 Throttle: 1.74 amps sustained
1/2 Throttle: 6.36 amps sustained
3/4 Throttle: 21.84 amps sustained
95% Throttle: 46 amps sustained
100% Throttle 56 amps sustained



The Diamante is now as fun to land as it is to fly!

Status: offline 		Unfortunately I don't have the necessary equipment to capture and edit videos on my pc.

Performed a few flights yesterday, weather was absolutely wonderful, very stable air and just a little bit of wind (the right kind, parallel with the runway!).

I'm starting to really enjoy the Diamante, I didn't need the flaps however as I'm beginning to feel the stalling point and slow the plane before the runway so I just perform a 3 points kind of touch down with enough power to keep her light.

Status: offline 		I'm putting together one- my son has taken an acute interest.

Three minute wheel pant mounting. See pictures for detail.

Three steps in three minutes. Push the blind nut up against the top of the cutout, use pliers to push it in, and then put 3 or 4 drops of thick CA to secure it in place. The blind nut matches perfectly with the landing gear 4/40 screw hole and wheels have ample clearance around the wheels wells when mounted.

Status: offline 		Nice! There's not much stress on the pants so it should be OK. Let us know after a few landings if they hold well.

Just a personal choice but I would have use Epoxy instead of CA.
