Well, electric fans attached are pics of the Pwr. Maverick that I’ve been building with Jim Jennings assistance on the pwr. set-up. The plane is an enlarged Maverick to about 410 sq. in. This is made from a laser cut kit that Jim and I have been working on since about christmas. Some of you may have seen these fly at a couple of Muncie contests this spring. The pwr. system on this model produces 370 watts of pwr. swinging an 8 x 4 APC prop 😯 . The motor is an AXI 2212-12, Jeti 18 amp controller, Starlink timer, and a Li-Po 3 cell 1200mah 30c battery (11.1v). The plane with battery ways in at 17 ozs. Initial glide tests are very promising. My test field this year is now in 6 feet tall corn so my test flying is very limited 🙁 Hope to have it ready for Muncie “B” electric. See you’all there.

Very nice job done! Now the fun begins…good luck and long flights!07/21/2008 at 11:32 pm #46044
Very nice, Scott.
The color scheme seems vaguely familiar, as if I’ve seen a similar pattern somewhere before.
The battery looks pretty vulnerable. Any thoughts of moving it to the side?07/22/2008 at 1:53 am #46045Jim JenningsParticipant
The battery is protected by the landing skid. I have been flying this configuration for some time without issue. In theory the weight low on the model should help the transition. It is also the best position to eject from in the event of a harder than anticipated landing. It will be interesting to have both of your models in the air at the same time. More confusing than 3 generations of Jennings with the same name on the flight line.07/24/2008 at 1:51 pm #46046
Sorry Dan, I didn’t try to copy your color scheme and wasn’t aware I was doing it until I got the two inner panels complete, and than it was an AH S”” 😳 . Went to all white wing tips and a full color stab with white wing tips. Hopefully this will help in the differentiating (sp) in the air!!! 😉
Scott07/24/2008 at 10:16 pm #46047
Ah, right, NOW I remember where I’ve seen the scheme. Some towline guy Europe had a glider like that in ’01 at Vegas, after the WC in Lost Hills. He was a nice fellow.08/05/2008 at 3:57 pm #46048
Well the Nats for B electric is over and due to pilot error the Pwr. Maverick was reduced to scrap! 👿 👿 😥 Jim and I trimmed our models Sunday afternoon and the pwr. Mav. was flying excellent and on a ten second motor run was very very high. Monday morning dawned just fine, did my first test flight with no issues. On first timed flight stupid pilot launched plane flat and the Pwr Mav. dove in under full pwr. 👿 Needless to say I had alot of pieces to pick up. I had to dig the motor out of the ground! Well that ended my B electric for the day so I turned my attention to assisting Jim Jennings Jr. set a new “B” Electric record of 24 maxes. Jim’s plane was the Same Maverick that I was flying and It was a site to see floating in the sky!!! Well, back to build another Pwr. Maverick!

Sorry to hear about your Maverick, the next one will be even better(at least thats how I consol myself).
Congrats to Jim Jr on the record of 24 maxes that must have been a marathon.
Do any of you guys foresee rules changes coming as technology advances? Ie. Ruduce motor runs and extended maxes were field permitt.08/06/2008 at 12:25 pm #46050
Mike, Yes! I for see changes in the next rule change sequence and with the performance that Jim and I achieved with these two ships I think we’ll see alot more participation in Electric and some great development in the near future. As this was my first foray into electric and being as successfull(except for pilot error) as I was I’ve already cleared my board of a tow liner and layed out the plans for another Pwr. Mav. You’ve gota get you’a one or two!!!

I’m working on it. I tore the nose off the Shocker and extended it and I’m now laminating up a new firewall and side pods. May look a little goffy but it is intend to be a learning project. I have a Maverick 500 kit from the guy who was making that high zoot kit a few years ago. Sorry can’t remeber his name. That is the one I have my eye one as the future project.08/06/2008 at 6:09 pm #46052AnonymousInactive
Have you modified the Jeti ESC for free flight, or is there some conversion or add-on.I have plenty of brushless motors for RC but would like to make a FF model.We have a class in England called E30.We also have F1Q of course.What sort of timer do you use?08/08/2008 at 8:26 pm #46053AnonymousInactive
I’ll take a stab at this as all the knowledgeable ones are probably at the nationals.
No mods are necessary to the controller it is just a matter of programming, made much easier if you have the programming card. There is a thread on the forum how to do that, it is very simple.
There are several different timers out there. Just depends on how much you want to spend and what features you need. Also a thread on the forum for that as well. I took the advice of everyone here and bought the Starlink. Looks simple enough just a matter pushing a button (all be it many times) to enter the required parameters.
I too have a ton of motors from my R/C stuff but the trend here is much higher KV motors that I use in R/C.
I hope that will hold you until some can give you better and more complete information.08/10/2008 at 12:45 am #46054
I am back from Muncie. Tuesday notwithstanding, it was a good week. Heat wasn’t a real issue.
B Electric on Monday witnessed a terrific performance by Jim. I knocked out 12 maxes with no ‘squeekers’. That left me in 2nd place, 12 maxes behind. Rich ivers had 11 maxes and just stopped. We were tied at 11 for a while. I didn’t want do a 50 yard dash to break a tie, so I flew one more. Dick Ivers dropped one around 9 or 10. Lots of guys marvelled at my planes performance, which is plenty good. Jim got 50% higher in 10 seconds. There is no substitute for altitude.
Regarding performance and the current rules:
2 minutes on 10 seconds no challenge for these planes. 5 seconds fpr 2 minutes won’t be a challenge for long. I spoke with a lot of guys this week and we exchanged thoughts and ideas. There is a general consensus that B Electric needs attention. We are 2 years away from the next rules cycle. I don’t think we can wait 2 years. I think the event needs an emergency rules proposal to limit some performance. The marathons that will ensue with the current rules will limit participation. I can say that I will not fly it again at 10 seconds for 2 minutes. I don’t want devote a whole day to it.
For Roseberry– Starlink can make chip to do whatever you want. That can elimnate some button pushing. He made me 2. I used both at the Nats. F1Q was 3 minute maxes. Each has 5 motor run choices and a fixed DT time. One is 2 min and the other 3 min. I just push for motor run and its ready to launch. Pretyy sweet setup, I thought.
I think Scott’s thread was hijacked. Many apologies Scott. I think Atlanta bunch collected your trophies. It was good seeing you.08/11/2008 at 5:58 pm #46055
Doc, sorry I haven’t gotten back to you sooner but I was out of town all weekend. As far as the controller goes, no special mods. other than the proper programing. Takes 10 seconds with a programming card. Like the rest of the respondents the Starlink is my choice for the timer. Very simple to operate and changing flight parameters takes less than a couple of minutes to change out the chip of choice. I’ve already got my next “B” electric Maverick on the board. It will be ready for Lawerenceville in early October. One thing of note to the readers. Jim’s ship was running an F1Q legal battery. In other words Jim could have flown the same plan in F1Q with no changes! I think we have to give Jim alot of credit for developing a Maverick type ship but with a little different air foil. As those of you at the Nats can attest to the glide on this plane is absolutely great! I am going to build one for “A” gas with on O.S. 10 on it! Look out “A” classic gas!!!

I am afraid I am completely ignorant of the basics, as all the programming instructions with my ESCs were for RC. If there is no Rx then what do you do with the receiver lead? My programming has all been with the Tx throttle stick
