    Most of my take off's have been from a hard surface but on the odd occasion that I fly off grass then I find that a small push to get the aircraft moving is all that is needed. The outriggers seem to be the issue so one day I will bend some skids into them to reduce the drag. Peter the retract looks very good when I do a low fly past and cycle the wheel up and down. As for the flying I cannot tell any difference with the wheel up or down. John

    Top picture showing my electric conversion and the other two showing the retract. F1 moved forward to accomodate the short electric motor, aalso the retracted wheel. John

    For your info, I bought one of those cheap electric retract units via ebay and have mounted mine onto a plate just behind behind the main former 1 with a cutout under the front fuselage and wing. The retract then works forwards. A cutout in the front of the wing is also needed to get the gear in the correct position. I tend now to buy Overlander 3548 motors and fit them into whichever aircraft that I am making so there is one in my harlequin as well. The fournier flies for 12 minutes on a 3cell 2200 and on recharge I find that there is about 30% of the charge still remaining. Mine flies like all Peter Millers planes, very well.

    Trevor, has your RV4 flown yet? For your info my RV3 has now had 150 flights using a Thumper 4250, 600 kv motor ( it was spare at the time of installation). It flies both on 3 & 4 cells, on 3 the prop is 14x10 and on 4 cells it is 14x7. Flight times are 10 minutes on 2300 x 4cell but I like to fly low and slow.

    OK that one went through so here is a pic of the front end in build. A new F1 has been made 3" forward of the plan version, the 1/8 ply cut former is where F1 was on plan. Motor just mounts at the front.

    Martyn Thanks for the advice however I am better at building and flying than I am with the computer. I tried to copy the picture but could not paste it into "my photos". Copy and paste works ok in my own files but not here. Any suggestions? It is now past midday and the sun is coming out so as I am retired I am off flying.

    Details are as follows but remember that I used a spare motor which flew my Fougray well. Motor- Tornado 4250. 3-7 lipo capable. 600kv. 720 watt max 60 amp esc as that was what I had in my stock. First flights were using 11.1v, 2200ma battery with a ground wattage of 350. Approx 6 minutes I will obtain a 4s battery with 3600ma to give me more watts and a longer flight time If I could work out how to add an image then I would send one with the modified front end.
