Went back and found the post. Sonic tronic makes sprung hinges that could be used to hold the door open.

Did not know that fact! Thanks! Well, if I have issues, may go and modify it to the side. But, remember, this is a sports jet, and I don't see any benifit for it to be on the side, verses the front. At least on the front, it does act as a small speed brake with the gear down.

Reminds me of the BD5j nose door.

Everyone at the field thought it looked like a BD5, because of the fat fuselage in the front and skinny exhaust tube. I remember the Budwiser one and 007. One thing that did concern me though, is that the strut springs seem soft, but according to CARF, they have been designed for this model. Has anyone else used the gear and had a firm landing to test them out?

Hi
Great looking jet
I also did not make door in front wheel
I try to keep it simple
What a beutiful air field

Thank you on the compliment! You should see the other two jet fields that I belong. They are even nicer fields, with 600+ paved runway, verses the one in the video of 450 ft, with that hill to the West that you see the jet taxi down too. I flew my Flash out of the field in the video, and once comfortable with the jet, plan to fly it at SPARKS too. Ocala is the most beautiful jet field for scenery and ammenities, but Cape Coral, has a better flying area with less trees and flatter ground.

You will not need to test the gear , the plane is the sweetest landing machine you will ever fly, I have many flights on mine and many others , yes gear is strong and problem free, just don't push down on the fin when pushing out full of fuel! This makes gear bottom.

LOL>>>>>Now you know why I asked about the gear!! I was pushing down on the rudder to push it into place, and sure enough, it bottomed out. Now I know! Thanks! I am truly looking forward to flying it.

Mark! Your S.W.A.G was exactly what I was doing wrong! Of course on landing, it is also about 7# lighter too.

Hey Guys!!

Had a GREAT Day today!! At a last minute invitiation by Andy Kane, Mr USA CARF Rep, who I have bought my last 3 CARF's from over the years. He happened to be in Cape Coral on vacation and getting ready for the SeaHawks Gathering of the Giants, on March 16-17th, I think. It is EXTREMELY jet friendly field, and I do belong to the Club, despite it is a 120 miles away from my home. I was fortunate enough to have Andy Kane present for the maiden of my Viper and to go over last minute details to see if I had anything out of the unusual on my jet, or more importantly, missed something extremely important. It was nice to have Andy K. as my spotter and coach through out the flight. Andy told me exactly what to look for in the maiden and the trimming of the jet, which was minimal. The maiden went uneventful, other then a little weather vaining, due to the crosswind, on landing, so that is more pilot technique. I have attached a couple pictures of the day!! If you can make Cape Coral Gathering of the Giants, please come!! Mac Hodges will be there with his B-29, just a lot of fun!

RCFD, congratulations, told you it was nice, the Viper as a plane never appealed to me until I flew the comp arf model, it is so user friendly and easy to put together and operate, also the quality of the plane ,components, fuel tank gear fixings and fittings are so above the rest, so glad you are loving it. Looks great in the pictures, by the way it was not a scientific wild a##s guess, I had done the same thing and tried to push mine by the fin when it was full:-))))

Congrats Dan. on your maiden. I remember when i first saw this model fly at Florida jets . The designer Stephan Voelker had everyones attention. With its superb flying.

Thank you! I have only had the one flight on it, but it is very light on the controls and very easy jet to fly. Not sure why they aren't selling that much here in the USA. Great jet! Also, on an earlier statement of mine, saying that I wished CARF would fix the seams a little better. Andy K. told me they do, and I just have to custom order the jet and they will do any paint scheme or fix the seams or whatever the customer wants on his jet. But, it does take some time from 4-6 months order time. I have always bought them when the kits were already here in the US. So, my earlier statement is kind of wrong. Again, I appreciate all of Andy's help! He is a great guy to deal with both from a customer stand point and as a pilot to respect. Last year, Andy even help me solve some trimming issues that I was having with my F-18, and not the brand they carry. Buy from Andy here in the US!

Hi guys.
Do you know if there is a light system for this jet and a metal nozzle also?
Thanks.

Achilles.

Hi Dan
I had to put 400 gram of lead to balance it
Did you need tadd also weight to balance your viper
Please advice

Fellow Viper Pilots!! I wrote the following to my gas and turbine students for a learning lesson. Maybe some of he new guys can learn too.

Hey Guys!

I thought I would share my learning experience with you on the trouble shooting of a new jet or complex plane. On the battery system, I am using 2- 7.4 V Lipo 2200 mah batteries. These batteries then go to the Fromco Wolverine switch. I love this switch, because it regulates the battery drawl at an even rate, and each battery, when recharged, always end up with in 50 ma. If they don't, then you have an issue.
Well, since this is a new jet, new Fromco Wolverine, new batteries, new regulators, and I am wiring it all, ***** can happen. I now have only three different charges on the jet from a 3 days of different flying. Prior to the maiden, both batteries charged within 50 mah. So, to me the system was perfect. For the second flight, charging the batteries, #1 was taking less charge in ma, then #2. I thought initially, that it was just the difference in the two new batteries from storage charge. The charge prior to the 2 & 3 flight. The #1 battery only took 6 ma and the #2 took #362 ma. I thought that maybe I didn't have the regulators adjusted correctly, so I adjusted them to 5.9 volts each. By the way, they arrive at 5V. So, you want to increase them to the 6V, to get maximum return from each servo. This is why you paid the $$ for them.......the torque!!
Flew 3 flights last week, and went to charge them today, to hopefully fly tomorrow. #1 took 40 ma, and #2 took 810 ma.......I thought, OK, something is wrong, because this switch always balances the batteries. Regulators have now been equaled and drawling the same V. The switch is assumed to be correct from the factory, and since I have had several of these switches, they all work flawless.
So, started to investigate the battery connections. Sure enough, #1 battery Dean's plug, even though the first charge was close to #2, something happen to the cold solder joints during the battery charges and drains during the flights and charges, and the plug failed on both wires. Bad solder job on my part. So, essentially, I have been flying the Viper on one battery, even though, during the initial power up, blue lights show the #1 system to be working, and it ground test OK. This is why a single battery operator often looks confused after the lock out and loss of a plane, thinking, "What happened, everything tested normal on the ground!!"
Guys, this is why I have learned it is important on the more expensive jets/planes to keep flight and battery logs. Didn't think much of it in the smaller glow stuff. But, right here, my jet was talking to me, if I had forgotten the previous charge or wasn't smart enough to read the signs it was telling me, I could have lost the jet, and thankful that I didn't loose it. Pay attention to your planes and jets. Don't assume, that just because the ding, beep or bell went off on the charger, all is good at home! They do normally tell and "talk" to you prior to failure. Full scale jets always talked to you before the system failed. You just have to be observant and look for the signs of change. This is also the other reason of a dual battery system. IF, I had only had the one battery system on the jet, and a bad battery connection on that main battery, that tested normal and good on the ground, I would probably no longer have this jet. I am now charging #1 battery with the new plug and hopefully proper solder joints, and it took: 728 ma!!! Lesson learned, pass it on! Dan

PS- Nose gear door works flawless!! Easy set up, easy usage!

Good Morning Zeev!

I didn't install a full cockpit, and have sence installed two H9 35% helmet head pilots, that weigh nothing. On the initial balance, by the way, I don't have the balance jig, and just hanging it from the wing tube. With the UAT full, and it is located near the air intakes, main tank empty, gear down(balance goes tail heavy with nose wheel retracts), I initially installed 20 oz (567grams) of lead in the empty nose section in front of the gear. Of course, all 3 Lipos are mounted in the nose section, two 2S on the shelf, and engines 3S-3600ma, but didn't weight them. I have 6 flights on it now, and for todays flight, I have reduced the nose weight by an 1.5oz. I asked Andy Kane if this was normal, since he was at CC for my maiden. He told me that the cockpit kit with pilots weights about a pound, so it was ok and normal. The last 3 flights, I started to see what the jet can do. After a couple minutes out of the main tank, inverted flight, I was still holding considerable down elevator to hold level flight, and on the knife edge, the jet is pulling to the canopy. This is the reason that I am reducing the lead weight in the nose. Zeev, after todays flights, I still may take even more out of it. But, the airspace that I am flying at today, doesn't have the space to make the jet perform aerobatics for the up winds and down winds. This field is tight and it is basically a yank and bank field, and a go vertical field. Will keep you posted! Dan

Hey Guys, what are you using for pilots in the Viper ? I can't fine any at the right scale ?

RCFlyerDan

My Feedback: (54)

I am using the 35% H9 Helmet heads. Will have a better picture later. I bought them in white, then painted them to match the jet's scheme.

NP....maybe this company in Germany would have some or a place to get them, since they carry the cockpit? The cockpit is the last one on the page.
