MacGregor have still been buying some stuff from relaunched JR. Its like the old days before everyone expected to surf their phone on the toilet and find everything listed...its not. Try contacting them, even use the phone option on your gizmo, lots of information is available from old fashioned speaking. Sure the days of them stocking things went with the original company, the discounts went with that too, for years the UK was the cheapest place to buy JR, I'd sell it into Europe at full rrp and get asked how I sold it so cheap!!

There are a lot of pilots now using gyros in slow scale models, some notable ones at the Nats in scale! The Powerbox igyro3e has a 4 x setting exactly for this. So effectively 400% gain, Std gyros would not be sensitive for roll, and slow on pitch. The iGyro works on the slowest models and I've seen it flown in a President Stamp with 30 year old (slow) servos. Many display pilots use gyros...even in slow flying models, it make the model look amazingly stable. Also some set the model tail heavy (neutral) and use the gyro to stabilise the craft in pitch. All in one Rx/gyros are a world away from what the Powerbox gyros offer. Anyone wants to discus a requirement 01923 270405 office hours.

From my shelves! I've been a main Graupner agent for over 20 years. Graupner did/do a 2.4m wood Extra 330 based on Gernot Bruckmann design, they recommend this motor and I built one for a customer and test flew it for him. It worked great, so when I got the Hybrid Extra from CARF I skipped the DLE 61 first thought and went electric since I have plenty of 6s packs from 90 size heli's and the motors were on a super cheap offer. I'll do a better test once the temperature allows the cells an easier time. But I was finishing at 3.82ish after the 6.5 minute flights, with electric its a case of flying a schedule-high power stuff at the beginning of the flight and flat controline inverted circuits and alike at the end, like this the cells won't be 'stressed' as the voltage drops and you can eek out another 30secs on the end. I have 6-9KW EDF models and you get used to coasting once you are 3/4 through the flight. Dave

I have a set of Overlander 5800 35c packs, flying 6 1/2 mins on two sets of 45c 5000 and one on the 5800 35c gave me a very similar end voltage on each cell. It was not that warm and the packs were not warmed to 30 degrees for optimum discharge. I have a Graupner 8028-190 motor since they had it on special and i'm running a Graupner Electric 22 x 10 at the moment. I have a 24 x 10 to experiment with when its warm again. On the 22 x 10 it prop hangs just above mid stick and punches out well. Dave

No, there was no camera the day I test flew it (3 weeks back) and I've not flown it since. Did you ever post your final weight? I was happy with mine, with 12s Overlander 45c 5000's its 8.42kg ready to fly. Flies light too! Might not fly it again until its warm, I started the build back in May and finished it in Nov with other commitments! Dave

I have a CARF Hybrid Extra with four MacGregor 5921HV and 1 x 6928HV on rudder, I'm using a Powerbox Sensor Switch HV (so output 7.4v) with two 1000mAh Overlander Rx Li-Pos and I get three flights inc some 3-D. DW

I still have lots of ST parts, less of the commonly wanted Carb and exhaust parts. Any 10-11% oil fuel with 0-10% nitro works fine, best with an OS F four stroke plug to protect the plug element in the huge head bowl. Electric starter is not needed, prime it well (big cylinder volume) plug on you can feel it kick. Bounce back technique works well.

Our club operates an A cert minimum to fly a turbine-with a spotter/helper who is B cert and Jet approved. Even a B cert (C cert) is not enough to have you signed off to fly turbine models-you still must have a spotter, but once you are signed off the spotter does not have to be a B+or jet approved. The logic is someone who has a cert and jet experience still might struggle to fly in our safe airspace. People come from huge open spaces or airfield operation and they need to prove they are spatially aware enough to operate a turbine model at our site. The JMA do operate a B only rule, mainly because we operate more than one model in the air and the meetings are too busy to allow for people who might not have the required skill or safety knowledge.

The nosing over is generally because the wheels are not in line or toe in. The ones I have seen tend to be set with slight toe out for wheel and door fit in the wing. Check they are (ideally) fractionally toe in.

You don;t give a size, but Graupner and Macgregor sell ready made horns of a larger size

If its the BNF version the factory are daft enough to have the two aerials fore and aft...so flying away or towards the Tx you have little range. I pushed a hole up into the wing at 90 degrees, angled up and slid one aerial up that.

Sean and Dave Woods are members of our club (PMFC) both enjoy flying electric models on the flat. Sean built my 6th Birthday present...one of his glider designs, dad crashed it (into me) knocking me unconscious on Ivinghoe shortly after...must tell my mother some time, we kept that a secret from her She knew when dad broke my arm at Croxley Moor...he did a lot of injuring, me, himself and I'm sure others )

I've been flying one since the first batch-the second one only arrives the end of this month. I use a 5000 6s 50c Overlander pack in mine, I have also used the 35c 4250 6s pack from the same company. With the 5000 all the way back its still a tiny bit nose heavy, but it still climbs in knife edge! Flown mainly from grass the gear copes with the weight just fine. Take off flap is always used and take off roll on grass is 30m. Full flap passes are lock solid. Full gear doors and lights add to the look. Nose probe unscrews and I 'plug' it into the cockpit area to store. Its a really well sorted package, I fly 5 minutes mixed aeros, near 6 minutes with out any long verticals.

There are several being built! Perfect timing with so many indoor groups operating through the winter.

Nothing changes for us over what happened in August 2016. The factory continues making stuff and new products are being worked on...with long time JR employees involved. JR Propo were effectively as design house and a legal agreement continues. New servos are being developed (top range) and the new Rx's are due 1st qtr 2018.
